Dental care in patients with periodontal disease and hearing impairment: a scoping review / Atención odontológica en pacientes con enfermedad periodontal y deficiencia auditiva: scoping review

Introduction: Literature shows that individuals with disabilities, including hearing impairment, often suffer from untreated dental caries, poor oral hygiene, and compromised periodontal health, leading to adverse effects on oral health. Objetive: This study aims to analyze current evidence concerning dental care strategies for controlling, managing, and preventing biofilm accumulation in patients with hearing impairment. Materials and Methods: A systematic search was conducted in the databases Scopus, Web of Science, SciELO and PubMed between April and May 2022 to identify articles establishing a relationship between periodontal disease and hearing disability. Full-text articles published in English or Spanish between 2012 and 2022 were included. Results: Seventeen articles met the inclusion criteria and were analyzed. These included cross-sectional studies, cohort studies, clinical trials, case reports, and case-control studies. Most studies reported fair to poor oral health status among individuals. Nine different interventions or management approaches for treating periodontal disease in patients with hearing impairment were identified. Conclusions: The current global evidence on the association between periodontal disease and hearing impairment is very limited. Dentists may need to employ various strategies to address communication barriers, as outlined in this study.

Periodontal status and mandibular biomechanics in rats subjected to hyposalivation and periodontitis / Estudio del estado periodontal y la biomecánica mandibular en ratas sometidas a hiposalivación y periodontitis

ABSTRACT Xerostomia emerges as a consequence of salivary gland hypofunction, and seriously compromises the integrity of hard and soft oral tissues, whileperiodontitis is an infectious disease characterized by biofilm accumulation, inflammation and alveolar bone resorption. Aim The aim this study was to compare the deleterious effects caused by experimental hyposalivation, periodontitis, and the combination of both on periodontal tissues and mandibular biomechanics in rats. Materials and Method Hyposalivation (group H) was induced through bilateral submandibulectomy. Periodontitis (group EP) was induced by injecting LPS (1 mg/ml) into the gingiva of the first lower molars. A third group was subjected to both conditions (group H+EP). Alveolar bone loss was evaluated by micro-computed tomography and histomorphometric analysis, and gingival inflammatory mediators were assessed by specific techniques. Biomechanical properties were evaluated in mandible. Results Alveolar bone loss increased similarly in groups H, EP and H+EP compared to control. Metalloproteinase (MMP2 and MMP9) activity was similar in H and control, but higher in groups EP and H+EP (MMP2: C 9644+2214, EP 34441+3336, H 5818+1532, H+EP 42673+3184; MMP9: C 5792+961, EP 14807+861, H 9295+520, H+EP 4838+1531). The rest of the inflammatory mediators evaluated increased in groups H, EP and H+EP to a greater or lesser extent with respect to the control, although in most cases, they were higher in groups EP and H+EP than in group H. The biomechanical properties of the mandible increased in group H compared to the other three groups. Conclusions Both hyposalivation and periodontitis cause periodontal damage, but hyposalivation also produces biomechanical alterations, causing more extensive deleterious effects than periodontitis.

RESUMEN La xerostomía surge como consecuencia de la hipofunción de las glándulas salivales y compromete seriamente la integridad de los tejidos orales duros y blandos, mientras que la periodontitis es una enfermedad infecciosa caracterizada por la acumulación de biofilm, inflamación y reabsorción ósea alveolar. Objetivo El objetivo del presente estudio fue comparar los efectos deletéreos causados por la hiposalivación y la periodontitis experimental, y la combinación de ambas sobre los tejidos periodontales y la biomecánica mandibular en ratas. Materiales y Método La hiposalivación (H) se indujo mediante una submandibulectomía bilateral. Por otra parte, la periodontitis (PE) se indujo mediante la inyección de LPS (1 mg/ml) en la encía de los primeros molares inferiores. Otro grupo se sometió a ambas condiciones (H+PE). La pérdida ósea alveolar se evaluó mediante tomografia microcomputarizada y análisis histomorfométrico, mientras que los mediadores inflamatorios gingivales fueron determinados mediante técnicas específicas. Se evaluaron las propiedades biomecánicas en la mandíbula. Resultados La hiposalivación aumentó la pérdida ósea alveolar en comparación con el control de forma similar a la PE y H+PE. La actividad de las metaloproteinasas (MMP2 y MMP9) fue similar en los grupos H y control, pero resultó mayor en los grupos PE y H+PE (MMP2: C 9644+2214, PE 34441+3336, H 5818+1532, H+PE 42673+3184; MMP9: C 5792+961, PE 14807+861, H 9295+520, H+PE 24838+1531). El resto de los mediadores inflamatorios evaluados aumentaron en mayor o menor medida en los grupos H, PE y H+PE respecto al control, aunque en la mayoría de los casos fueron superiores en los grupos PE y H+PE respecto al grupo H. Sin embargo, las propiedades biomecánicas de la mandíbula aumentaron en el grupo H con respecto a los otros grupos. Conclusiones Tanto la hiposalivación como la periodontitis causan daño periodontal, pero la hiposalivación también produce alteraciones biomecánicas, provocando efectos deletéreos más extensos que la periodontitis.

Changes of parameters associated with anemia of inflammation in patients with stage Ⅲ periodontitis before and after periodontal initial therapy / 北京大学学报(医学版)

Objective:To investigate the differences and similarities of parameters associated with ane-mia of inflammation between patients with stage Ⅲ periodontitis and periodontally healthy volunteers,and to explore the influence of periodontal initial therapy on those indicators.Methods:Patients with stageⅢ periodontitis and periodontally healthy volunteers seeking periodontal treatment or prophylaxis at De-partment of Periodontology,Peking University School and Hospital of Stomatology from February 2020 to February 2023 were enrolled.Their demographic characteristics,periodontal parameters(including pro-bing depth,clinical attachment loss,bleeding index),and fasting blood were gathered before periodontal initial therapy.Three months after periodontal initial therapy,the periodontal parameters of the patients with stage Ⅲ periodontitis were re-evaluated and their fasting blood was collected again.Blood routine examinations(including white blood cells,red blood cells,hemoglobin,packed cell volume,mean cor-puscular volume of erythrocytes,and mean corpuscular hemoglobin concentration)were performed.And ferritin,hepcidin,erythropoietin(EPO)were detected with enzyme-linked immunosorbent assay(ELISA).All data analysis was done with SPSS 21.0,independent sample t test,paired t test,and analysis of co-variance were used for comparison between the groups.Results:A total of 25 patients with stage Ⅲperiodontitis and 25 periodontally healthy volunteers were included in this study.The patients with stageⅢ periodontitis were significantly older than those in periodontally healthy status[(36.72±7.64)years vs.(31.44±7.52)years,P=0.017].The patients with stage Ⅲ periodontitis showed lower serum he-moglobin[(134.92±12.71)g/L vs.(146.52±12.51)g/L,P=0.002]and higher serum ferritin[(225.08±103.36)μg/L vs.(155.19±115.38)μg/L,P=0.029],EPO[(41.28±12.58)IU/L vs.(28.38±10.52)IU/L,P＜0.001],and hepcidin[(48.03±34.44)μg/L vs.(27.42±15.00)μg/L,P=0.009]compared with periodontally healthy volunteers.After adjusting the age with the co-variance analysis,these parameters(hemoglobin,ferritin,EPO,and hepcidin)showed the same trends as independent-sample t test with statistical significance.Three months after periodontal initial therapy,all the periodontal parameters showed statistically significant improvement.The serum hemoglobin raised[(146.05±15.48)g/L vs.(133.77±13.15)g/L,P＜0.001],while the serum ferritin[(128.52± 90.95)μg/Lvs.(221.22±102.15)μg/L,P＜0.001],EPO[(27.66±19.67)IU/L vs.(39.63± 12.48)IU/L,P=0.004],and hepcidin[(32.54±18.67)μg/L vs.(48.18±36.74)μg/L,P=0.033]decreased compared with baseline.Conclusion:Tendency of iron metabolism disorder and ane-mia of inflammation was observed in patients with stage Ⅲ periodontitis,which can be attenuated by periodontal initial therapy.

Evaluation of characteristics of periodontal probes

Aim: This study aimed to evaluate the millimeter distances and active tip diameters of different periodontal probes. Methods: Two types of periodontal probes were analyzed (North Carolina (15-UNC) and PCP-12). Two manufacturers were selected for each probe type. Digital images of the probes were obtained and the distances were measured using a software program. The diameter of the active tip was measured using a digital caliper. Both variables were measured by two trained and calibrated examiners. The data were analyzed using the Bland-Altman method and two-way ANOVA with Tukey's post-hoc test. Statistical significance was set at p<0.05. Results: A comparison of measurements between the 15UNC and PCP-12 probes showed a significant difference in all millimeter markings. The 15-UNC probe showed differences between the 3 and 12 mm markings. The PCP-12 probe only showed differences between the marks at the 12 mm mark. The 15-UNC probe had a similar active tip diameter between the two manufacturers. The PCP-12 probe showed a significant difference between the two manufacturers. Both types of probes had similar active tip diameters when compared by the two manufacturers. Conclusion: There was no standardization in relation to millimeter marks and tip diameters of the two types of periodontal probes produced by the two different manufacturers. The probe types exhibited little variability

Systemic benefits of periodontal therapy in patients with obesity and periodontitis: a systematic review

Abstract This systematic review aimed to answer the focused question: "What are the benefits of subgingival periodontal therapy on blood hematological and biochemical index, biomarkers of inflammation and oxidative stress, quality of life, and periodontal pathogen counts in patients with obesity and periodontitis?". A systematic literature search was performed in six databases: PubMed, Embase, LILACS, Web of Science, Cochrane and SCOPUS and other sources, and a manual search was conducted as well. Inclusion criteria were randomized and non-randomized clinical trials, and before-and-after studies on patients with obesity subjected to periodontal therapy. The results were synthesized qualitatively. Risk of bias within studies was assessed using RoB 2 and ROBINS-I tools. The certainty of evidence was evaluated following the GRADE approach. Three randomized controlled trials and 15 before-and-after studies were included. Randomized controlled trials were considered to have a low risk of bias, as compared to before-and-after studies assessed as having low, serious, and critical risks of bias. Non-surgical periodontal therapy plus azithromycin, chlorhexidine, and cetylpyridinium chloride reduced blood pressure and decreased serum levels of HbA1c, hsCRP, IL-1β, and TNF-α. Salivary resistin level also decreased in patients with obesity and periodontitis after therapy and chlorhexidine mouth rinse. Before-and-after data suggest an improvement in total cholesterol, LDL, triglycerides, insulin resistance, C3, GCF levels of TNF-α, chemerin, vaspin, omentin-1, visfatin, 8-OHdG, and periodontal pathogen counts after therapy.

Assessment of the nursing staff's knowledge on periodontal disease and its associations with systemic changes / Avaliação do conhecimento da equipe de enfermagem sobre doença periodontal e suas associações com alterações sistêmicas

Abstract Introduction The maintenance of oral health in inpatients is essential, particularly to avoid complications arising from periodontal disease, which not only affect oral health but can also exacerbate systemic issues during hospitalization. Objective: This study aimed to assess nursing staff's knowledge regarding the management of periodontal disease and its association with systemic diseases. Material and method This cross-sectional observational study was conducted in a general referral hospital of the Brazilian National Health System (SUS). A total of 504 nursing professionals completed a self-administered 24-item questionnaire on relating to oral care procedures and the importance of oral health in hospitalized patients. Data were analyzed using descriptive analysis and the chi-squared test (α = 0.05). Result Most respondents (97.8%) believed that oral infections can affect a patient's general health and that oral hygiene is important during hospitalization. However, knowledge deficits were identified. The oral effect of periodontal disease was considered moderate by 49.3% of the participants, and 74.6% believed that sugar was the most common cause of periodontal disease. Conclusion Nursing professionals are aware of the importance of maintaining oral hygiene and the relationship between periodontal and systemic diseases. However, their dental hygiene practice knowledge is limited. A training program on oral healthcare for inpatients and the inclusion of oral hygiene topics in the curricula of nursing professionals are recommended.

Is there a difference in the oxidative stress levels between type 2 diabetic individuals with and without periodontitis? Systematic review / Existe diferença nos níveis de estresse oxidativo entre indivíduos com diabetes tipo 2 com e sem periodontite? Revisão Sistemática

Objective: The authors' aim in this systematic review was to verify the scientific evidence for difference of oxidative stress biomarkers in individuals with type 2 diabetes mellitus with and without periodontitis. Material and Methods: Observational studies, baseline data of prospective and interventional studies were searched on the following databases: Virtual Health Library, Web of Science, PubMed, Embase, Scopus, Cochrane Library, Opengrey and Google Scholar. The electronic search was performed in June 01, 2020 until May 17, 2024 with alerts until June 01, 2024. The quality assessment and the certainty of the evidence of the included studies were evaluated through Fowkes and Fulton's checklist and GRADEpro Guideline Development Tool. Results: Of 988 relevant articles, the authors included 9 studies for the final analysis. Among those studies, 4 cross-sectional, 3 case-control, and 2 interventional studies were included. The analysis of non-randomized clinical trials properly reported most of the criteria analyzed in Summary questions (Bias, Confounding and Chance) as present in 3 studies. In six studies confounding factors were no detected. Due to the variation in the study results and clinical/methodological heterogeneity, a meta-analysis was not appropriate. The studies reported high concentrations of oxidizing agents and low antioxidants levels in individuals with type 2 diabetes mellitus and periodontitis when compared to with no periodontitis. Conclusion: Considering the few studies found, the methodological flaws, few markers studied and absence homogeneity in the evaluation of redox balance markers, as well as, the very low certainty of the evidence among included studies, it was not possible to determine whether there are or not differences in the oxidative stress levels in individuals with type 2 diabetes with and without periodontitis, and therefore, further prospective observational and interventional studies are recommended. (AU)

Objetivo: O objetivo dos autores nesta revisão sistemática foi verificar a evidência científica para a diferença de biomarcadores de estresse oxidativo em indivíduos com diabetes mellitus tipo 2 com e sem periodontite. Material e Métodos: estudos observacionais, dados de base de estudos prospectivos e intervencionistas foram pesquisados nas seguintes bases de dados: Biblioteca Virtual em Saúde, Web of Science, PubMed, Embase, Scopus, Cochrane Library, Opengrey e Google Scholar. A busca eletrônica foi realizada no período de 01 de junho de 2020 até 17 de maio de 2024, com alertas até 01 de junho de 2024. A avaliação da qualidade e a certeza da evidência dos estudos incluídos foi realizada através da lista de checagem Fowkes and Fulton's e da Ferramenta de desenvolvimento de diretrizes GRADEpro. Resultados: Dos 988 artigos relevantes, os autores incluíram 9 estudos para a análise final. Entre esses estudos, foram incluídos 4 estudos transversais, 3 de caso-controle e 2 de intervenção. A análise dos ensaios clínicos não randomizados relatou adequadamente a maioria dos critérios analisados nas questões resumo (Viés, Confundimento e Resultados ao caso) presentes em 3 estudos. Fatores de confusão não foram detectados em seis estudos. Devido à variação nos resultados do estudo e à heterogeneidade clínica/metodológica, não foi possível realizar uma meta-análise. Os estudos relataram altas concentrações de agentes oxidantes e baixos níveis de antioxidantes em indivíduos com diabetes mellitus tipo 2 e periodontite quando comparados a indivíduos sem periodontite. Conclusão: Considerando os poucos estudos encontrados, as falhas metodológicas, poucos marcadores estudados e ausência de homogeneidade na avaliação dos marcadores do balanço redox, bem como a baixíssima certeza da evidência entre os estudos incluídos, não foi possível determinar se há diferenças nos níveis de estresse oxidativo em indivíduos com diabetes tipo 2 associado e não à periodontite e, portanto, outras observações prospectivas e estudos de intervenção são recomendados (AU)

Prevalence of species of yellow, purple and green microbial complexes in endo-perio lesions: a systematic review

Abstract This review aimed to determine the prevalence of species of yellow, purple and green microbial complexes in root canals (RC) and periodontal pockets (PP) of teeth with endodontic-periodontal lesions. For this purpose, two reviewers searched the literature up to January 2022. Studies reporting the prevalence of species of the yellow, purple and green microbial complexes in teeth diagnosed with endodontic-periodontal lesions were included. The risk of bias of the included studies was assessed using the 14 criteria from the NIH Quality Assessment Tool. Of 1,611 references identified in the initial search, only four studies were eligible and included in the qualitative analysis. The profile and prevalence rates of bacterial species in RC and PP varied among the included studies: levels of Agregatibacter actinomycetemcomitans (12% RC, 58% PP), Capnocytophaga granulosa (10% RC, 35% PP), Capnocytophaga sputigena (15-70% RC, 0-30% PP), Streptococcus mitis (30% RC, 35% PP), Streptococcus sanguinis (30% RC, 35% PP), and Veillonella parvula (70% RC, 50% PP) were identified. The high methodological heterogeneity prevented grouping and quantitative analysis of data. The risk of bias was considered 'moderate' for all studies. The included studies identified the presence of seven bacterial species belonging to the yellow, purple, and green microbial complexes in RC and PP, but with different prevalence rates. Future clinical studies are encouraged to investigate the presence and role of these species in the occurrence and development of endodontic-periodontal lesions.

Diabetes tipo II. A terapia periodontal não cirúrgica pode favorecer o controle glicêmico do paciente? / Type II Diabetes. Does nonsurgical periodontal therapy improve glycemic control in patientes? / Diabetes tipo II. ¿Puede la terapia periodontal no quirúrgica mejorar el control glicémico del paciente?

Introdução:A doença periodontal corresponde àcondição que acomete os tecidos de proteção e/ou suporte do dente através de uma inflamação crônica causadapor patógenos.Estacondição pode ser modificada ou associada às doenças sistêmicas, como por exemplo, o diabetes mellitus tipo II (DM2).Objetivo:Avaliar quais os efeitos da terapia periodontal não cirúrgica sobre o controle glicêmico de pacientes diagnosticados com DM2.Metodologia:Revisão integrativa elaborada a partir de pesquisas clínicas randomizadas indexadas nas bases de dados Pubmed, Embase, Cochrane, Web of Science e BVS, na qual foram utilizados os descritores "periodontal diseases treatment", "glycemic control" e "metabolic control".Resultados:Dos trabalhos avaliados, seis foram selecionados para compor a revisão, tendo em vista os critérios de inclusão e exclusão estabelecidos. Logo, é notório que a terapia periodontal básica indica melhora no controle glicêmico dos pacientes com DM2, de acordo comanálise da HbA1c e PCR,portanto, com base nos resultados dessa pesquisa, o tratamento periodontal não cirúrgico parece contribuir para o controle metabólico. Apesar disso, alguns estudos se opõem aoresultadodo controle glicêmicodesses pacientes, reforçando a existência de variáveis que interferem nos resultados da pesquisa, como os níveis de hemoglobina, estágio da doença periodontal, amostra, dietae atividade física dos pacientes.Conclusões:O resultado deverá ser avaliado com maior cautela, tendo em vista as possibilidades de variáveis presentes nesse tipo de pesquisa. Por fim, ensaios controlados devem ser realizados para alcançar um maior esclarecimento a respeito dos efeitos da terapia periodontal não cirúrgica no controle glicêmico de pacientes com DM2 (AU).

Introduction:Periodontal disease is a condition in which protective or supportive tissues of the tooth are affected by chronic inflammation caused by pathogens. This condition may be modified or associated with systemic diseases such as type 2 diabetes mellitus (T2DM).Objective:To evaluate the effects of nonsurgical periodontal therapy on glycemic control in patients diagnosed with T2DM. Methodology:An integrative review was performed using randomized clinical trials indexed in PubMed, Embase, Cochrane, Web of Science, and BVS databases. The descriptors "periodontal disease treatment," "glycemic control," and "metabolic control" were used. Results:From the reviewed studies, six were selected for the review considering the established inclusion and exclusion criteria.Basic periodontal therapy improves glycemic control in patients with T2DM, as evidenced by analysis of glycated hemoglobin (HbA1c) and polymerase chain reaction (PCR). Therefore, based on the results of this research, nonsurgical periodontal treatment contributes to metabolic control. However, some studies contradict the effect of glycemic control in these patients, reinforcing the presence of variables that interfere with research results, such as hemoglobin levels, stage of periodontal disease, sample, dietand physical activity of patients. Conclusions:The results should be evaluated with more caution considering the potential variables present in this type of research. Finally, controlled trials should be conducted to understand better the effects of nonsurgical periodontal therapy on glycemic control in patients with T2DM (AU).

Introducción: La enfermedad periodontal es una condición en la cual los tejidos protectores o de soportedel diente se ven afectados por una inflamación crónica causada por patógenos. Esta condición puede modificarse o asociarse a enfermedades sistémicas como la diabetes mellitus tipo 2 (DM2). Objetivo: Evaluar los efectos de la terapia periodontal no quirúrgica en el control glucémico en pacientes diagnosticados con DM2. Metodología: Se realizó una revisión integradora utilizando ensayos clínicos aleatorizados indexados en las bases de datos de PubMed, Embase, Cochrane, Web of Science y BVS. Se utilizaron los descriptores "tratamiento de enfermedades periodontales", "control glucémico" y "control metabólico". Resultados: De los estudios revisados, se seleccionaron seis para la revisión, considerando los criterios de inclusión y exclusión establecidos. La terapia periodontal básica mejora el control glucémico en pacientes con DM2, como se evidencia en el análisis de la hemoglobina glicosilada (HbA1c) y la reacción en cadena de la polimerasa (PCR). Por lo tanto, basándose en los resultados de esta investigación, el tratamiento periodontal no quirúrgico contribuye al control metabólico. Sin embargo, algunos estudios contradicen el efecto del control glucémico en estos pacientes, lo que refuerza la presencia de variables que interfieren en los resultados de la investigación, como los niveles de hemoglobina, el estadio de la enfermedad periodontal, la muestra, la dieta y la actividad física de los pacientes. Conclusiones: Los resultados deben evaluarse con mayor precaución, considerando las posibles variables presentes en este tipo de investigación. Por último, se deben realizar ensayos controlados para comprender mejor los efectos de la terapia periodontal no quirúrgica en el control glucémico en pacientes con DM2 (AU).

Un estudio de la obesidad y la enfermedad periodontal: una revisión de la literatura / A study of obesity and periodontal disease: a review of the literature

Las enfermedades periodontales son enfermedades inflamatorias causadas por bacterias patógenas en el biofilm subgingival, que afectan los tejidos circundantes y de soporte de los dientes, el periodonto. Estas conexiones inexplicables pasan a primer plano a medida que las enfermedades orales, como la enfermedad periodontal, echan raíces. El desafío bacteriano exacerba la producción de citoquinas por el epitelio gingival, lo que resulta en una inflamación incontrolada que conduce a la pérdida de dientes en adultos de diferentes poblaciones. La prevalencia de estas enfermedades aumenta con el envejecimiento, la retención más prolongada de los dientes y el aumento de la incidencia entre la población. Se realiza una búsqueda en los motores bibliográficos de Medline, PubMed y Cochrane encontrándose 33 artículos de valiosa necesidad, de los últimos cinco años. Esta revisión presenta los puntos que resaltan el poder desarrollar nuevos métodos capaces de detectar a las enfermedades periodontales en las primeras etapas (AU)

Periodontal diseases are inflammatory diseases, caused by pathogenic bacteria in the subgingival biofilm, which affect the surrounding and supporting tissues of the teeth, the periodontium. These inexplicable connections come to the fore as oral diseases, such as periodontal disease, take root. Bacterial challenge exacerbates cytokine production by the gingival epithelium, resulting in uncontrolled inflammation leading to tooth loss in adults from different populations. The prevalence of these diseases increases with aging, longer retention of teeth, and increasing incidence among the population. A search was carried out in the bibliographic engines of Medline, PubMed and Cochrane, finding 33 articles of valuable need, 5 years old. This review of the article presents the points that stand out to be able to develop new methods capable of detecting these diseases in the early stages (AU)

Quality of life related to periodontal disease in diabetic patients under the health subsidized regime in Manizales / Calidad de vida relacionada con enfermedad periodontal en pacientes diabéticos del régimen subsidiado de Manizales

Introducción: la calidad de vida relacionada con la salud bucal es un tema relevante que involucra la relación de la odontología con las enfermedades crónicas no transmisibles como la diabetes, dada su relación bidireccional. En este trabajo se resalta la importancia de revisar el impacto que generan las alteraciones periodontales en la calidad de vida de pacientes diabéticos. El objetivo de este estudio fue establecer la calidad de vida relacionada con el estado periodontal en pacientes diabéticos pertenecientes al régimen subsidiado de Manizales. Métodos: se observaron 90 adultos diabéticos pertenecientes al programa de diabetes del régimen subsidiado mediante entrevista estructurada, aplicación del instrumento OHIP-14 (Perfil de Impacto de la Salud Oral en la Calidad de Vida) y observación directa del estado periodontal, con el fin establecer el índice de extensión y severidad periodontal, descripción del índice OHIP-14, establecer su relación con variables sociodemográficas y con el estado de salud periodontal. Resultados: se encontró una prevalencia de impacto según el OHIP-14 del 44,4%, extensión del impacto con un promedio de 1,58 (IC: 1,0-2,1) y una severidad del impacto de 6,7 (IC: 6,2-7,8). Al consolidar los resultados del OHIP-14 por dimensión, se observó que el mayor impacto correspondió a la dimensión de dolor físico, con un porcentaje del 81,1%. El menor porcentaje se presentó en las dimensiones de Incapacidad Social y Discapacidad o Minusvalía con un 34,4%. Conclusiones: aunque en la población estudiada, la presencia de enfermedad periodontal ejerció pobre impacto en calidad de vida, éste fue mayor en las dimensiones de impacto de dolor físico y malestar psicológico.

Introduction: quality of life related to oral health is a relevant topic that involves the relationship of dentistry with chronic noncommunicable diseases such as diabetes, given its bidirectional relationship. This study emphasizes the importance of reviewing the impact of periodontal alterations on the quality of life of diabetic patients. The objective of this study was to establish the quality of life related to periodontal status in diabetic patients belonging to the subsidized regime of Manizales. Methods: 90 diabetic adults belonging to the diabetes program of the subsidized regime were observed by means of a structured interview, application of the OHIP-14 instrument (Oral Health Impact Profile on Quality of Life) and direct observation of periodontal status, to establish the index of periodontal extension and severity, description of the OHIP-14 index, establish its relationship with sociodemographic variables and with periodontal health status. Results: we found a prevalence of impaction according to OHIP-14 of 44.4%, extent of impaction with an average of 1.58 (CI: 1.0-2.1) and severity of impaction of 6.7 (CI: 6.2-7.8). When consolidating the OHIP-14 results by dimension, it was observed that the greatest impact corresponded to the physical pain dimension, with a percentage of 81.1%. The lowest percentage was presented in the dimensions of Social Incapacity and Disability or Handicap with 34.4%. Conclusions: although in the population studied, the presence of periodontal disease had a poor impact on quality of life, this was greater in the dimensions of physical pain and psychological discomfort.

Relación de la enfermedad periodontal inflamatoria crónica con enfermedades sistémicas / Relationship of chronic inflammatory periodontal disease with systemic diseases

Introducción: La enfermedad periodontal es una infección inmunoinflamatoria crónica de origen multifactorial. Puede avanzar a nivel sistémico por el paso de bacterias y sus productos al torrente sanguíneo, lo cual constituye un factor de riesgo para alteraciones sistémicas. La revisión bibliográfica se realizó de julio 2022 hasta febrero 2023. Se utilizaron las bases de datos PubMed, SciELO y Elsevier y el motor de búsqueda Google Académico. Objetivos: Describir la relación de la enfermedad periodontal inflamatoria crónica con enfermedades sistémicas. Desarrollo: La medicina periodontal estudia la relación que existe entre las periodontopatías y enfermedades sistémicas, como las cardiovasculares, cerebrovasculares, pulmonares, la renal crónica, la artritis reumatoide y el Alzheimer. Las bacterias provenientes de las bolsas periodontales pasan hacia la circulación sanguínea, producen infección metastásica y daño metastásico, mediante la producción de endotoxinas, lipopolisacáridos e inflamación metastásica. Conclusiones: La enfermedad periodontal crónica constituye un factor de riesgo para el desarrollo de enfermedades cardiovasculares, pulmonares, renales, trastornos cerebrovasculares, artritis reumatoide y el Alzheimer debido a reacciones inflamatorias producidas por microorganismos patogénicos; se establece una relación bidireccional entre estas enfermedades y las periodontopatías(AU)

Introduction: Periodontal disease is a chronic immunoinflammatory infection of multifactorial origin. It can advance at a systemic level due to the passage of bacteria and their products into the bloodstream, which constitutes a risk factor for systemic alterations. The bibliographic review was carried out from July 2022 to February 2023. The PubMed, SciELO and Elsevier databases and the Google Scholar search engine were used. Objectives: Describe the relationship of chronic inflammatory periodontal disease with systemic diseases. Development: Periodontal medicine studies the relationship between periodontopathies and systemic diseases, such as cardiovascular, cerebrovascular, pulmonary, chronic kidney disease, rheumatoid arthritis and Alzheimer's. Bacteria from periodontal pockets pass into the blood circulation, producing metastatic infection and metastatic damage, through the production of endotoxins, lipopolysaccharides and metastatic inflammation. Conclusions: Chronic periodontal disease constitutes a risk factor for the development of cardiovascular, pulmonary, renal diseases, cerebrovascular disorders, rheumatoid arthritis and Alzheimer's due to inflammatory reactions produced by pathogenic microorganisms; A bidirectional relationship is established between these diseases and periodontopathies. The analysis of this relationship and the mechanisms by which it occurs guarantees the development of a more integrative care practice(AU)

Unvaccinated periodontal patients with a history of COVID-19: clinical findings in a Dental School setting

Abstract This study analyzed the periodontal clinical data of individuals with a history of COVID-19 treated in a dental school during the pandemic in 2021 before vaccination. Methods: This analysis included individuals older than 18 years with no history of systemic disorders other than systemic arterial hypertension. Individuals who had COVID-19 were classified according to the World Health Organization as asymptomatic, with mild, moderate, severe, or critical symptoms. Results: A total of 95 individuals were evaluated, which included 24 with a history of COVID-19. Seventeen percent had been asymptomatic, 21% had mild, 25% moderate, 21% severe, and 17% critical symptoms, including intubation. Individuals with no history of COVID-19 presented significantly lower measurements of probing depth (p=0.003; Mann-Whitney test) and clinical attachment level (p=0.002) compared to individuals with a history of COVID-19. A significant negative association was found between bleeding on probing and the severity of characteristics of COVID-19 (rho= -0.233; p=0.023). Conversely, positive associations between the values of probing depth (rho= 0.292; p=0.004) and mean clinical attachment level (rho= 0.300; p=0.003) and the characteristics of COVID-19 were found. Conclusions: The periodontal data shows that patients who had COVID-19 before vaccination may present a worse periodontal status when compared to patients in the same clinical setting with no history of COVID-19. However, a more extensive study should confirm it with more participants.

Resumo Este estudo analisou os dados clínicos periodontais de indivíduos com histórico de COVID-19 tratados em uma escola de odontologia durante a pandemia em 2021, antes da vacinação. Métodos: Essa análise incluiu indivíduos maiores de 18 anos sem histórico de distúrbios sistêmicos, exceto hipertensão arterial sistêmica. Os indivíduos que tiveram COVID-19 foram classificados de acordo com a Organização Mundial da Saúde como assintomáticos, com sintomas leves, moderados, graves ou críticos. Resultados: 95 indivíduos foram avaliados, incluindo 24 com histórico de COVID-19. 17% eram assintomáticos, 21% tinham sintomas leves, 25% moderados, 21% graves e 17% críticos, incluindo intubação. Os indivíduos sem histórico de COVID-19 apresentaram medidas significativamente mais baixas de profundidade de sondagem (p=0,003; teste de Mann-Whitney) e nível de fixação clínica (p=0,002) em comparação com indivíduos com histórico de COVID-19. Foi encontrada uma associação negativa significativa entre o sangramento à sondagem e a gravidade das características da COVID-19 (rho= -0,233; p=0,023). Por outro lado, foram encontradas associações positivas entre os valores de profundidade de sondagem (rho = 0,292; p = 0,004) e o nível médio de apego clínico (rho = 0,300; p = 0,003) e as características da COVID-19. Conclusão: Os dados periodontais mostraram que os pacientes que tiveram COVID-19 antes da vacinação podem apresentar um pior estado periodontal quando comparados a pacientes no mesmo ambiente clínico sem histórico de COVID-19. No entanto, um estudo mais extenso deve ser realizado para confirmar tal achado com maior número de participantes.

Using the Response Surface Methodology for Periodontitis Diagnosis / Uso da Metodologia de Superfície de Resposta para Diagnóstico de Periodontite

Response surface methodology (RSM) consists of mathematical and statistical techniques to develop models which help to understand the influence of various factors on a dependent variable of interest. The feasibility of RSM use to detect cases of periodontitis and its correlated factors has not yet been evaluated. This study developed mathematical models for periodontitis diagnosis independent of periodontal probing using the RSM. Demographic, socioeconomic, behavioral, systemic, local factors, and periodontitis were assessed in 176 volunteers. Periodontitis case was defined according to three different definitions: 1) ≥3 sites with clinical attachment level (CAL) ≥4 mm; 2) at least one site with CAL ≥4 mm and bleeding on probing; 3) ≥2 proximal sites with CAL ≥3 mm and ≥2 proximal sites with probing depth (PD) ≥4 mm (not on the same tooth) OR 1 site with PD ≥5 mm. 4th-degree polynomial equations showed high coefficients of determination (R²= 1) and were used to represent the mathematical models of periodontitis cases. According to definition 1, the diagnosis of periodontitis was accurate by including in the model: age, sex, education level, plaque index (PI), number of missing teeth, previous hygiene instructions, and body mass index (BMI). According to definition 2, the diagnosis of periodontitis was accurate by including in the model: age, sex, education level, income, PI, previous oral hygiene instructions, frequency of brushing and type of toothbrush, and use of mouthwash in the model. For an accurate diagnosis of periodontitis according to definition 3, the model included: age, education level, IP, number of missing teeth, previous oral hygiene instruction, BMI, and diabetes. The multifactorial mathematical models were able to diagnosis periodontitis according to different periodontitis case definitions using only variables of easy evaluation and non-invasive. (AU)

A metodologia de superfície de resposta (MSR) consiste em técnicas matemáticas e estatísticas para desenvolver modelos que ajudam a entender a influência de vários fatores em uma variável dependente de interesse. A viabilidade do uso da MSR para detectar casos de periodontite e seus fatores correlacionados ainda não foi avaliada. Este estudo desenvolveu modelos matemáticos para diagnóstico de periodontite independente da sondagem periodontal usando a MSR. Fatores demográficos, socioeconômicos, comportamentais, sistêmicos, locais e periodontite foram avaliados em 176 voluntários. O caso de periodontite foi definido de acordo com três definições diferentes: 1) ≥3 locais com nível de inserção clínica (NIC) ≥4 mm; 2) Um local com NIC ≥4 mm e sangramento à sondagem; 3) ≥2 locais proximais com NIC ≥3 mm e ≥2 locais proximais com profundidade de sondagem (PS) ≥4 mm (não no mesmo dente) OU 1 local com PS ≥5 mm. Equações polinomiais de 4º grau apresentaram altos coeficientes de determinação (R²= 1) e foram utilizadas para representar os modelos matemáticos dos casos de periodontite. De acordo com a definição 1, o diagnóstico de periodontite foi preciso ao incluir no modelo: idade, sexo, escolaridade, índice de placa (IP), número de dentes perdidos, instruções de higiene anteriores e índice de massa corporal (IMC). De acordo com a definição 2, o diagnóstico de periodontite foi preciso ao incluir no modelo: idade, sexo, escolaridade, renda, IP, instruções prévias de higiene bucal, frequência de escovação e tipo de escova dental e uso de enxaguatório bucal no modelo. Para um diagnóstico preciso de periodontite de acordo com a definição 3, o modelo incluiu: idade, escolaridade, IP, número de dentes perdidos, instrução prévia de higiene oral, IMC e diabetes. Os modelos matemáticos multifatoriais foram capazes de diagnosticar a periodontite de acordo com diferentes definições de casos de periodontite usando apenas variáveis de fácil avaliação e não invasivas.

Revisão crítica da nova classificação das periodontites / Critical review of periodontitis classification

Para o correto diagnóstico e tratamento da doença periodontal precisamos usar as classificações da doença periodontal. A mais recente foi proposta pela Academia Americana de Periodontia em conjunto com a Federação Europeia de Periodontia. Para a assimilação dos conceitos estabelecidos precisamos avaliar criticamente as informações que foram trazidas pelo consenso realizado há quase 6 anos. O objetivo do presente estudo é revisar o tópico periodontite da classificação, de forma a colaborar para o entendimento dessa doença pelos estudantes de graduação.

The periodontal diseases classifications are important for the correct diagnosis and treatment of periodontal diseases. The most recent classification was proposed by the American Academy of Periodontology in a consensus with the European Federation of Periodontology. For the assimilation of the established concepts, a critical evaluation of the information that was brought by the consensus almost 6 years ago, must be performed. The objective of the present study is to review the periodontitis topic of the new classification, in order to contribute to the understanding of this disease by undergraduate students.

Periodontitis en niños sanos de 3 años: dos casos con seguimiento a 5 años / Periodontitis in healthy 3-year-old children: two cases with 5-year follow-up

Objetivo: La periodontitis en dentición primaria es ex- cepcional en niños sin enfermedades sistémicas. El objetivo de este informe es describir las características clínicas y ra- diográficas de dos casos de niños de 3 años sistémicamente sanos con periodontitis, y su tratamiento con seguimiento a 5 años. Casos clínicos: En ambos casos, a los 3 años de edad los niños fueron derivados al especialista en periodoncia por su odontopediatra debido a la pérdida muy temprana de inci- sivos inferiores. El examen clínico y radiográfico mostró pér- dida de inserción clínica, pérdida ósea y movilidad dental en otros incisivos superiores e inferiores. Se realizó la intercon- sulta médica y se descartó que los niños padecieran enferme- dades relacionadas con el diagnóstico de periodontitis como manifestación de una enfermedad sistémica. El tratamiento consistió en la instrucción de medidas de higiene bucal que debían ser ejecutadas por los padres, ins- trumentación subgingival, antisépticos locales, medicación antibiótica sistémica y mantenimiento periodontal. No se rea- lizaron extracciones como parte del tratamiento. En ambos casos uno de los incisivos presentes al momento de la con- sulta se perdió prematuramente, antes de los 4 años. El resto de los incisivos primarios cumplieron su ciclo normal. Luego de 5 años de seguimiento, a la edad de 8 años, ambos niños presentaban los incisivos y los primeros molares permanentes periodontalmente sanos y el resto de los dientes primarios sin signos de periodontitis (AU)

Aim: Periodontitis in primary dentition is exceptional in children without systemic diseases. The objective of this article is to describe the clinical and radiographic charac- teristics of two cases of systemically healthy 3-year-old chil- dren with periodontitis, and their treatment, with a 5-year follow-up. Clinical cases: In both cases, at 3 years of age, the chil- dren were referred to a periodontic specialist by their pediat- ric dentist, due to the very early loss of lower incisors. Clin- ical and radiographic examination showed loss of clinical attachment, bone loss and dental mobility in other upper and lower incisors. A medical consultation was carried out and diseases related to the diagnosis of periodontitis as a mani- festation of a systemic disease were ruled out. The treatment consisted of instruction on oral hygiene measures that had to be carried out by the parents, subgingival instrumentation, local antiseptics, systemic antibiotic medication, and perio- dontal maintenance. No extractions were performed as part of the treatment. In both cases, one of the incisors present at the time of consultation was lost prematurely, before the age of 4 years. The rest of the primary incisors completed their normal cycle. After 5 years of follow-up, at the age of 8 years, both children showed periodontally healthy incisors and first permanent molars, and the rest of the primary teeth without signs of periodontitis (AU)

Impacto do uso sistêmico de estatinas e de bisfosfonatos nos tecidos periodontais: revisão narrativa / Impact of the systemic use of statins and bisphosphonates in the periodontal tissues: narrative review

Introdução: A literatura tem apontado uma possível relação entre diversas condições sistêmicas e as doenças periodontais. Dentro das doenças sistêmicas que podem gerar o uso crônico de medicamentos, com potencial associação com as doenças periodontais, destacam-se a hipercolesterolemia e o uso de estatinas; e as doenças do metabolismo ósseo e o uso de bisfosfonatos. Objetivo: Dessa maneira, o presente estudo objetivou revisar a literatura sobre o efeito das estatinas e dos bisfosfonatos nos parâmetros clínicos e radiográficos periodontais de indivíduos adultos. Resultados: Apenas estudos observacionais em humanos foram incluídos. Um estudo mostrou que, em pacientes que apresentam doença periodontal e usam estatina, houve 37% menos bolsas periodontais (profundidade de sondagem ≥4mm) quando comparadas aos que não utilizam a medicação, além de apresentarem menor índice de carga inflamatória e menor perda de inserção clínica. Em relação aos bisfosfonatos em indivíduos com doenças que envolvem o metabolismo ósseo, sugere-se que a utilização do fármaco tem obtido resultados positivos nos parâmetros periodontais, como menores sinais clínicos de inflamação gengival, menor profundidade de sondagem, menor perda de inserção clínica e maior nível de osso alveolar, quando comparados aos que nunca realizam essa terapia. Conclusão: Dessa forma, as estatinas e os bisfosfonatos apresentam efeitos promissores, em pacientes sob tratamento para suas respectivas condições sistêmicas, na melhoria dos parâmetros periodontais, porém é importante salientar que são necessários mais estudos sobre o assunto para melhor entender os reais efeitos a longo prazo do uso desses fármacos.(AU)

Introduction: The literature showed a possible relationship between several systemic conditions and periodontal diseases. Within the systemic diseases that can generate the chronic use of these drugs, potentially related with periodontal diseases, it may be cited the hypercholesterolemia and the use of statins; and bone metabolism diseases and the use of bisphosphonates. Objective: In this sense, the present study aimed to review the literature about the effect of statins and bisphosphonates in the periodontal parameters of adults individuals. Results: Only observational studies in humans were included. A study showed that, in patients with periodontal disease and users of statins, there 37% fewer periodontal pockets (probing depth ≥4mm) when compared to those who do not use the medication, as well as having a lower rate of inflammatory burden and less loss of clinical insertion. Regarding the bisphosphonates in individuals diagnosed with diseases involving bone metabolism, it was suggested that the use of the drug has obtained positive results in periodontal parameters, such as a greater absence of plaque, less clinical signs of gingival inflammation, less probing depth, lower level of clinical insertion and higher level of alveolar bone when compared to those who never undergo this therapy. Conclusion: Thus, statins and bisphosphonates have promising effects in patients under treatment for their respective systemic condition in improving periodontal parameters, but it is important to emphasize that further studies on the subject are needed to better understand the long-term effects of the use of these drugs.(AU)
