RESUMO

La gingivitis se ha definido como una inflamación de la encía caracterizada por edema, eritema, cambio de la morfología normal, exudado acuoso y hemorragia de interés mundial. El objetivo fue evaluar el efecto dos pastas dentales en pacientes jóvenes diagnosticados con gingivitis en la ciudad de Cusco-Perú en el año 2022. La investigación se realizó en alumnos de la Facultad de Economía de la Universidad Nacional San Antonio Abad del Cusco todos ellos diagnosticados con gingivitis en el mismo año. El estudio se desarrolló bajo un diseño experimental pre-test post-test con dos grupos experimentales cada uno con n=15. Evaluados con el índice de placa de Löe & Silness y el índice gingival de Löe & Silness (IG). Los participantes fueron orientados a cepillar los dientes con el dentífrico tres veces al día, por un periodo de 2 semanas. Se utilizó como instrumento de recolección de datos una matriz de registro para la medición antes y después de aplicado el tratamiento en la cual se plasmaron los índices de placa e índice gingival de Löe & Silness. Resultó que los sujetos del estudio en su gran mayoría presentaron gingivitis moderada y un estado de higiene oral regular. Con lo cual concluimos que la pasta dental aplicada en el Grupo I resultó más efectiva en la recuperación de pacientes con gingivitis. El dentífrico con contenido de Ratania fue bien tolerado por los participantes, no existiendo ningún tipo de alteración de tipo alérgica en los tejidos bucales, por lo tanto, no interrumpió el tratamiento.


Gingivitis has been defined as an inflammation of the gum characterized by edema, erythema, change in normal morphology, watery exudate, and bleeding of global interest. The aim was to evaluate the effect of two toothpastes on young patients diagnosed with gingivitis in the city of Cusco, Peru in 2022. The research was conducted on students from the Faculty of Economics at the National University of San Antonio Abad in Cusco, all diagnosed with gingivitis in the same year. The study was carried out under a pre-test post-test experimental design with two experimental groups, each with n=15. Evaluated using the Löe & Silness plaque index and the Löe & Silness gingival index (GI). Participants were instructed to brush their teeth with the toothpaste three times a day for a period of 2 weeks. A data collection instrument was used, a record matrix for measurement before and after treatment application, where the Löe & Silness plaque and gingival indices were recorded. The study subjects mostly presented moderate gingivitis and a regular oral hygiene status. Therefore, we conclude that the toothpaste applied in Group I was more effective in the recovery of patients with gingivitis. The toothpaste containing Ratania was well tolerated by the participants, with no allergic tissue alterations in the oral tissues, thus not interrupting the treatment.

RESUMO

Periodontal disease is a highly prevalent chronic inflammatory disease that affects the tissues that support the teeth, while leukemia is a type of malignous cancer that affects the production of blood cells. Recent studies suggest that immune response and microbial disbiosis related to periodontal disease may be associated with an increased risk of developing leukemia and may affect its prognosis, as well as leukemia type and treatment may also have effects on the periodontium, demanding a interdiscipinary approach of these patients. The aim of this study was to conduct a literature review to assess the association between periodontal disease and leukemia in adult patients. An electronic database serch using the descriptors was performed. Clinical studies with periodontal examination in adult individuals with leukemia were selected. After literature search, 9 studies were reviewed. Gingival bleeding and periodontal pockets were frequent findings. Periodontitis prevalence varied among studies, ranging from 29% to 82,4% in patients diagnosed with leukemia. The relationship between periodontal disease and leukemia is complex and multifaceted and there are few studies available in adults, with heterogeneous exam protocols. Still, the high prevalence of gingivitis and periodontitis found in the studies suggest that periodontal diagnosis and treatment could be a helpful tool to prevent further complications in leukemia treatment.


A doença periodontal é uma doença inflamatória crônica altamente prevalente e que afeta os tecidos que sustentam os dentes, enquanto a leucemia é um tipo de câncer maligno que afeta a produção de células sanguíneas. Estudos recentes sugerem que a resposta imune e a disbiose microbiana relacionada a doença periodontal podem estar associadas a um risco aumentado de desenvolver leucemia e pode afetar o prognóstico da doença, assim como o tipo de leucemia e o tratamento também podem ter efeitos no periodonto, exigindo uma abordagem interdisciplinar desses pacientes. O objetivo deste estudo foi realizar uma revisão de literatura para avaliar a associação entre doença periodontal e leucemia em pacientes adultos. Foi realizada uma busca eletrônica em bancos de dados utilizando os descritores. Foram selecionados estudos clínicos com exame periodontal em indivíduos adultos com leucemia. Após busca na literatura, 9 estudos foram revisados. Sangramento gengival e bolsas periodontais foram achados frequentes. A prevalência da periodontite variou entre os estudos, sendo de 29% a 82,4% em pacientes diagnosticados com leucemia. A relação entre doença periodontal e leucemia é complexa e multifacetada e existem poucos estudos disponíveis em adultos, com protocolos de exames heterogêneos. Ainda assim, a alta prevalência de gengivite e periodontite encontrada nos estudos sugere que o diagnóstico e o tratamento periodontal podem ser uma ferramenta útil para prevenir maiores complicações no tratamento da leucemia.

RESUMO

El objetivo del artículo es reportar el desempeño clínico en el control y disminución de la placa bacteriana en pacientes adolescentes mediante un gel y barniz con partículas S-PRG. Se realizaron tratamientos con materiales bioactivos con tecnología GIOMER en 2 pacientes. En el primer caso se realizó una profilaxis con Pro Care Gel (S-PRG) en un paciente de 15 años con problemas neuromotores para eliminar la placa y posteriormente, se aplicó un barniz con partículas de S-PRG para prevenir la formación de biofilm. En el segundo caso, un adolescente de 15 años normoreactivo con inflamación gingival recibió el tratamiento profilaxis con PRG Pro Care Gel.Se observó una disminución de placa bacteriana tras la profilaxis con el gel Pro Care y la aplicación del barniz en el primer caso. Además, existió una baja incidencia de biofilm incluso después de 11 meses de la aplicación del barniz. En el segundo caso, a las 2 horas de aplicación, se observó una disminución total de la placa. Clínicamente se observó el bueno desempeño clínico de los materiales con partículas de S-PRG, como lo demuestra la literatura científica en cuanto a la reducción de la formación de placa bacteriana en las estructuras dentarias, la desinflamación gingival, proporciona bienestar a los pacientes y restaura la salud bucal de forma menos invasiva.


The objective of the article is to report the clinical performance in the control and reduction of bacterial plaque in adolescent patients using a gel and varnish with S-PRG particles. Treatments with bioactive materials with GIOMER technology were performed in two patients. In the first case, prophylaxis was performed with Pro Care Gel (S-PRG) in a 15-year-old patient with neuromotor problems to eliminate plaque and subsequently, a varnish with S-PRG particles was applied to prevent biofilm formation. In the second case, a normal 15-year-old adolescent with gingival inflammation received prophylaxis treatment with PRG Pro Care Gel. A decrease in bacterial plaque was observed after prophylaxis with the Pro Care gel and the application of the varnish in the first case. Furthermore, there was a low incidence of biofilm even after 11 months of varnish application. In the second case, after 2 hours of application, a total decrease in plaque was observed. The good clinical performance of materials with S-PRG particles was clinically perceived, as demonstrated by the scientific literature in terms of reducing the formation of bacterial plaque in dental structures, gingival disinflammation, providing well-being to patients and restoring oral health in a less invasive way.

RESUMO

OBJECTIVE To investigate the potential mechanism of procyanidin on rats with gingivitis by regulating phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/vascular endothelial growth factor (VEGF) signaling pathway. METHODS The rat model of gingivitis was constructed by sewing the neck of the first maxillary molar with silk thread+applying maltose on the gum+feeding with 20% sucrose solution and soft food. Forth-eight model rats were randomly divided into model group, procyanidin group (160 mg/kg), 740Y-P group (PI3K/Akt signaling pathway activator, 0.02 mg/kg), and procyanidin+ 740Y-P group (procyanidin 160 mg/kg+740Y-P 0.02 mg/kg), with 12 rats in each group; another 12 rats were selected as control group; each medication group was treated with corresponding drugs intragastrically or/and intraperitoneally, once a day, for 7 consecutive days. Twenty-four hours after the last administration, the gingival index of rats was measured; the levels of interleukin- 18 (IL-18), inducible nitric oxide synthase (iNOS) and alkaline phosphatase (ALP) in gingival crevicular fluid, as well as the levels of superoxide dismutase (SOD), catalase (CAT) and reactive oxygen species (ROS) in gingival tissues of rats were detected; the pathological changes in gingival tissues were observed; the expression levels of PI3K/Akt/VEGF signaling pathway- related proteins in gingival tissues of rats were detected. RESULTS Compared with control group, the gingival tissues of rats in the model group had severe pathological damage,which was manifested as local tissue expansion and congestion, new capillaries, degeneration and loss of collagen fibers and disorder of arrangement, and a large number of inflammatory cell infiltration in the gingival sulcus wall. The gingival index, the levels of IL-18, iNOS, ALP in gingival crevicular fluid, the level of ROS in gingival tissues, the phosphorylations of PI3K and Akt, as well as the protein expression of VEGF in gingival tissues were significantly increased; the levels of SOD and CAT in gingival tissues of rats in model group were significantly decreased (P<0.05). Compared with model group, the pathological damage to the gingival tissues of rats in procyanidin group was reduced, and all quantitative indicators were significantly improved (P<0.05); 740Y-P could reverse the improvement effect of procyanidin on various indicators (P<0.05). CONCLUSIONS Procyanidin may alleviate gingival tissue damage, and improve gingival inflammation and oxidative stress in rats with gingivitis by inhibiting PI3K/Akt/VEGF signaling pathway.

RESUMO

Abstract This study aimed to estimate the prevalence and extent of bleeding on probing and calculus in 12-year-old schoolchildren of Quito, Ecuador, and evaluate the associated factors. We conducted an epidemiological survey with a representative sample of 1,100 12-year-old schoolchildren from public schools in the urban area of Quito, Ecuador. We assessed the periodontal health using the Community Periodontal Index (CPI). The prevalence and extent of the periodontal condition was based on the presence of at least one site with bleeding on probing (BOP), and the presence of dental calculus was also evaluated. We used univariate and multiple multilevel Poisson regression analyses to verify the association between the independent variables and the number of sextants with BOP and calculus. The prevalence of BOP and calculus was 92% and 69.9%, respectively. The adjusted mean of the affected sextants was 4.3 and 2.2 for BOP and calculus, respectively. The mother's schooling and malocclusion were associated with the number of sextants with bleeding. The mother's schooling and dental caries experience were associated with calculus. Gingival bleeding and the presence of dental calculus are highly prevalent in 12-year-old schoolchildren from Quito. Gingival bleeding is associated with maternal education and malocclusion, and dental calculus is associated with maternal education and dental caries.

RESUMO

Introducción: Existen datos controversiales y pocas revisiones acerca del efecto de los enjuagues herbales como complemento en la higiene bucal de pacientes con enfermedad periodontal. La reducción en costos y efectos secundarios de estos enjuagues, en comparación con los convencionales, los colocan en una posición prometedora para el cuidado de la salud. Objetivo: Comparar el efecto de los enjuagues bucales convencionales con los enjuagues herbales en la mejora de los siguientes parámetros periodontales: índice gingival, de placa, sangrado al sondaje, profundidad al sondaje y nivel de adherencia clínica en pacientes adultos con gingivitis o periodontitis. Métodos: Se realizó la revisión en las bases de datos MEDLINE/PubMed, Scopus, Web of Science, BVS y EBSCO, para identificar ensayos clínicos donde se comparen enjuagues bucales comerciales vs. herbales, publicados entre 2018 y 2022. Siguiendo las recomendaciones PRISMA, se utilizó el sistema PICO para determinar la pregunta clínica y una ecuación de búsqueda con criterios de elegibilidad. Resultados: De 485 estudios identificados inicialmente se analizaron 25 ensayos clínicos, de los cuales la mayoría se realizaron en la India (11) y en pacientes sin problemas sistémicos (23). Las muestras evaluadas fueron desde 19 hasta 318 sujetos, con edades comprendidas entre 18 y 74 años. El menor tiempo de seguimiento fue de siete días y el mayor de 180 días. Con respecto a los enjuagues evaluados, 20 ensayos usaron clorhexidina y 18 enjuagues a base de plantas herbáceas. Así mismo, seis estudios reportaron efectos adversos y tres reportaron conflictos de interés. Conclusiones: Los aceites esenciales combinados con curcumina redujeron el índice de placa en mayor medida que el enjuague de clorhexidina, que es el estándar dorado. Así mismo, la mayoría de los enjuagues herbales estudiados tuvieron un efecto similar a este último para mejorar los parámetros periodontales.


Introduction: There are controversial data and few reviews about the effect of herbal rinses as an adjunct in oral hygiene in patients with periodontal disease. The reduction in costs and side effects of these rinses, in comparison with conventional rinses, place them in a promising position for health care. Objective: To compare the effect of conventional mouthwashes with herbal rinses in the improvement of the following periodontal parameters: gingival index, plaque index, bleeding on probing, probing depth and level of clinical adherence in adult patients with gingivitis or periodontitis. Methods: A review was performed in MEDLINE/PubMed, Scopus, Web of Science, BVS and EBSCO databases to identify clinical trials comparing commercial vs. herbal mouthrinses, published between 2018 and 2022. Following PRISMA recommendations, the PICO system was used to determine the clinical question and a search equation with eligibility criteria. Results: Out of 485 studies initially identified, 25 clinical trials were analyzed, of which the majority were conducted in India (11) and in patients without systemic problems (23). The samples evaluated ranged from 19 to 318 subjects, aged 18-74 years. The shortest follow-up time was seven days and the longest was 180 days. Regarding the rinses evaluated, 20 trials used chlorhexidine and 18 used herbal rinses. Also, six studies reported adverse effects and three reported conflicts of interest. Conclusions: Essential oils combined with curcumin reduced plaque index to a greater extent than the gold standard chlorhexidine rinse. Most of the herbal rinses studied had a similar effect to the latter in improving periodontal parameters.

RESUMO

Abstract The prevalence of gingivitis is substantial within the general population, necessitating rigorous oral hygiene maintenance. Objective This study assessed a Garcinia indica (GI) fruit extract-based mouthrinse, comparing it to a 0.1% turmeric mouthrinse and a 0.2% Chlorhexidine (CHX) mouthrinse. The evaluation encompassed substantivity, staining potential, antimicrobial efficacy and cytocompatibility. Methodology The study employed 182 tooth sections. For antimicrobial analysis, 64 extracted human teeth coated with a polymicrobial biofilm were divided into four groups, each receiving an experimental mouthrinse or serving as a control group with distilled water. Microbial reduction was assessed through colony forming units (CFU). Substantivity was evaluated on 54 human tooth sections using a UV spectrophotometer, while staining potential was examined on 64 tooth sections. Cytocompatibility was tested using colorimetric assay to determine non-toxic levels of 0.2% GI fruit extract, 0.1% Turmeric, and 0.2% CHX. Results Data were analysed with one-way ANOVA (α=0.05). Cell viability was highly significant (p<0.001) in the 0.2% GI group (64.1±0.29) compared to 0.1% Turmeric (40.2±0.34) and 0.2% CHX (10.95±1.40). For antimicrobial activity, both 0.2% GI (20.18±4.81) and 0.2% CHX (28.22±5.41) exhibited no significant difference (P>0.05) at end of 12 hours. However, 0.1% Turmeric showed minimal CFU reduction (P<0.001). Substantivity results at 360 minutes indicated statistically significant higher mean release rate in 0.1%Turmeric (12.47±5.84 ) when compared to 0.2% GI (5.02±3.04) and 0.2% CHX (4.13±2.25) (p<0.001). The overall discoloration changes (∆E) were more prominent in the 0.2% CHX group (18.65±8.3) compared to 0.2% GI (7.61±2.4) and 0.1% Turmeric (7.32±4.9) (P<0.001). Conclusion This study supports 0.2% GI and 0.1% Turmeric mouth rinses as potential natural alternatives to chemical mouth rinses. These findings highlight viability of these natural supplements in oral healthcare.

RESUMO

Mouthwash is used to support brushing because it is distributed throughout the oral cavity. In this study, we examined the efficacy of a mixture of three hot water extracts (from Hordeum vulgare L, Apocynum venetum L, and Brasenia schreberi J. F. Gmel) for the purpose of developing an effective mouthwash. The mixture suppressed enhanced tumor necrosis factor α and matrix metalloproteinase 3 gene expression by Porphyromonas gingivalis lipopolysaccharide stimulation in human gingival fibroblasts. Furthermore, human studies using a mouthwash containing the plant extracts (MW) improved gingival index and bleeding on probing in the gum, and reduced the concentration of methyl mercaptan, which causes bad breath, in the mouth. These findings suggest that continued use of MW has positive effects on gingival inflammation and halitosis, and is useful for maintaining oral health.

RESUMO

Introdução: As gengivites são condições comuns em todas as populações, independente da faixa-etária. A indicação de agentes químicos como antissépticos bucais mostra-se importante prevenindo a formação de novo biofilme na superfície dental. Extratos vegetais têm sido propostos como possibilidades terapêuticas interessantes devido as características antimicrobianas e imunomoduladoras de diversos fitoterápicos. Objetivo: Realizar um levantamento bibliográfico sobre o uso das plantas medicinais no controle do biofilme dental para tratamento e prevenção da gengivite. Metodologia: foi realizada uma análise de dados secundários, através de uma revisão da literatura sobre a utilização de plantas medicinais na prevenção e tratamento da gengivite. Foram analisados artigos científicos publicados entre 2012 a 2021, obtidos nas bases eletrônicas de dados indexados no PubMed, Google Scholar, Lilacs e Scielo, que apresentaram resultados positivos e que tiveram a clorexidina como controle. Resultados: As informações obtidas foram apresentadas em três tabelas separando enxaguatórios e dentifrícios. Nos estudos que comparam colutórios à base de ervas com enxaguatório bucal com clorexidina 0,12%, em sua maioria, discorrem sobre a igualdade da eficácia na redução do biofilme dental e da gengivite. Nos dois trabalhos que avaliaram dentifrícios, pode-se notar que houve uma boa aceitação por parte dos pesquisados e não mostraram efeitos adversos. Conclusão: Os fitoterápicos são bem indicados como alternativas para manter a saúde gengival. Entretanto, devem ser realizados mais ensaios clínicos longitudinais para fundamentar seus efeitos a longo prazo, testando diferentes protocolos, concentrações e parâmetros clínicos de avaliação para esclarecer a relevância clínica destes produtos naturais no controle e tratamento da gengivite.


Introduction: Gingivitis is a common condition in all populations, regardless of age group. The indication of chemical agents such as mouthwashes prove to be important in preventing the formation of a new biofilm on the dental surface. Plant extracts have been proposed as interesting therapeutic possibilities due to the antimicrobial and immunomodulatory characteristics of several herbal medicines. Objective: To carry out a bibliographic survey on the use of medicinal plants in the control of dental biofilm for the treatment and prevention of gingivitis. Methodology: an analysis of secondary data was performed, through a literature review on the use of medicinal plants in the prevention and treatment of gingivitis. Scientific articles published between 2012 and 2021 were analyzed, from electronic databases indexed in PubMed, Google Scholar, Lilacs and Scielo, which presented positive results and which had chlorhexidine as a control. Results: The information was presented in three tables, two of which are separated between mouthwash and toothpaste. The herbal mouthwashes with 0.12% chlorhexidine found that most of them were equally effective in reducing plaque and gingivitis compared to the 0.12% chlorhexidine mouthwash. In the two studies that evaluated toothpastes, it can be noted that there was a good acceptance by those surveyed and they did not show adverse effects. Conclusion: Phytotherapics are well indicated as alternatives to maintain gingival health. However, further longitudinal clinical trials should be performed to substantiate their long-term effects, testing different protocols, concentrations and clinical evaluation parameters to clarify the clinical relevance of these natural products in the control and treatment of gingivitis.

Se analizaron artículos científicos publicados entre 2012 y 2021, de bases de datos electrónicas indexadas en PubMed, Google Scholar, Lilacs y Scielo, que presentaran resultados positivos y que tuvieran clorhexidina como control. Resultados: La información se presentó en tres tablas, dos de ellas separadas entre colutorio y pasta dentífrica. En los enjuagues bucales a base de plantas con clorhexidina al 0,12% se observó que la mayoría de ellos eran igual de eficaces para reducir la placa y la gingivitis en comparación con el enjuague bucal con clorhexidina al 0,12%. En los dos estudios que evaluaron los dentífricos, puede observarse que hubo una buena aceptación por parte de los encuestados y no mostraron efectos adversos. Conclusiones: Los fitoterápicos están bien indicados como alternativas para mantener la salud gingival. Sin embargo, se deben realizar más ensayos clínicos longitudinales para corroborar sus efectos a largo plazo, probando diferentes protocolos, concentraciones y parámetros de evaluación clínica para aclarar la relevancia clínica de estos productos naturales en el control y tratamiento de la gingivitis.

RESUMO

Abstract Based on a holistic concept of polymicrobial etiology, we have hypothesized that putative and candidate periodontal pathogens are more frequently detected in consortia than alone in advanced forms of periodontal diseases (PD). Objective To correlate specific consortia of periodontal pathogens with clinical periodontal status and severity of periodontitis. Methodology Subgingival biofilm was obtained from individuals with periodontal health (113, PH), gingivitis (91, G), and periodontitis (209, P). Genomic DNA was purified and the species Aggregatibacter actinomycetemcomitans (Aa), Aa JP2-like strain, Porphyromonas gingivalis (Pg), Dialister pneumosintes (Dp), and Filifactor alocis (Fa) were detected by PCR. Configural frequency and logistic regression analyses were performed to correlate microbial consortia and PD. Results Aa + Pg in the presence of Dp (phi=0.240; χ2=11.9, p<0.01), as well as Aa JP2 + Dp + Fa (phi=0.186, χ2=4.6, p<0.05) were significantly more associated in advanced stages of P. The consortium Aa + Fa + Dp was strongly associated with deep pocketing and inflammation (p<0.001). The best predictors of disease severity (80% accuracy) included older age (OR 1.11 [95% CI 1.07 - 1.15], p<0.001), Black/African-American ancestry (OR 1.89 [95% CI 1.19 - 2.99], p=0.007), and high frequency of Aa + Pg + Dp (OR 3.04 [95% CI 1.49 - 6.22], p=0.002). Conclusion Specific microbial consortia of putative and novel periodontal pathogens, associated with demographic parameters, correlate with severe periodontitis, supporting the multifactorial nature of PD.

RESUMO

Objective: to evaluate the impact of the COVID-19 pandemic on children and adolescents with cerebral palsy, comparing the gingival condition and the type of dental treatment before and after the interruption of dental care. Material and Methods: the retrospective longitudinal study consisted of 273 participants undergoing Dental Clinic of the AACD (Disabled Child Assistance Association), divided into three groups according to age: Group 1 (G1: 0 to 5 years and 11 months; n=137), Group 2 (G2: 6 to 11 years and 11 months; n=85) and Group 3 (G3: 12 to 17 years and 11 months; n=51). Sociodemographic, data, clinical pattern of cerebral palsy and use of medication were collected, evaluating the gingival condition by the gingival index and the type of dental treatment before the pandemic and during, nine months after the interruption of dental care. Chi-square, Fisher Exact and Kruskal-Wallis (α=5%) tests were used. Results: the groups were homogeneous in terms of sex (p=0.4581), race (p=0.1725), clinical pattern (p=0.3482) and use of antiepileptic drugs (p=0.3509). Regarding the gingival condition, in the period during the pandemic, there was a reduction in the number of participants with Gingival Index scores 0 and 1 and an increase in participants with scores 2 and 3 (p<0.05). As for the procedures performed, the three groups showed a reduction in preventive procedures (p<0.05) and an increase in surgical, periodontal and restorative procedures (p<0.05). Conclusion: it is concluded that the interruption of dental care for nine months during the COVID-19 pandemic in children and adolescents with cerebral palsy had a negative impact on oral health (AU)

RESUMO

Abstract Although periodontal disease is common during pregnancy, little is known about socioeconomic, behavioral, or biological determinants related to clinically assessed periodontal condition during this period. We assessed the prevalence of periodontal disease and associated factors in pregnant women. This population-based survey used data used from the 2015 Pelotas Birth Cohort Study, Brazil. Pregnant women expected to give birth between December 2014 and May 2016 were interviewed and clinically examined by trained dentist, with periodontal measures collected in all teeth, six sites per tooth. Outcomes were periodontitis (using the 2012 Centers for Disease Control and Prevention and the American Academy of Periodontology criteria) and gingivitis (by the 2018 European Federation of Periodontology/ American Academy of Periodontology classification). Multivariate hierarchical Poisson regression was used to assess the associations between socioeconomic, systemic, and clinical oral factors and periodontal disease. A total of 2,474 pregnant women participated in the study. Prevalence of periodontitis and gingivitis was 14.63% and 21.67%, respectively. Lower educational level and calculus were associated with higher prevalence periodontitis and gingivitis (P<0.05). Smoking was also associated with periodontitis (P=0.05), and lower frequency of toothbrushing (P=0.005) with gingivitis. Periodontal disease, especially gingivitis, was prevalent in pregnant women and their determinants were socioeconomic, environmental, and clinical oral health factors.

RESUMO

Introducción: El embarazo es una época de cambios para las mujeres. Se producen cambios en todo el organismo debido al aumento de los niveles de la hormona progesterona. La encía es un tejido clave para la acción de las hormonas esteroideas, por tal motivo los cambios clínicos en los tejidos periodontales se identifican durante los periodos de fluctuación hormonal. Objetivo: Sistematizar aspectos sobre qué es la gingivitis en el embarazo, cuáles son sus causas y consecuencias, y cómo tratarla de forma segura para la madre y el bebé. Método: Se realizaron revisiones bibliográficas donde se pudo abordar e interpretar las manifestaciones de la enfermedad periodontal durante el embarazo. Fueron examinados 20 artículos científicos de revistas nacionales e internacionales tanto en español y portugués de los últimos 5 años (2018-2022); de los 20 artículos se excluyeron 5, ya que no coincidían con el tema investigado. Resultados: Los efectos de los estrógenos y la progesterona en el periodonto han sido objeto de atención por los investigadores a lo largo de los años. Por esta razón los tejidos periodontales de la mujer son más susceptibles a esta patología durante el embarazo debido al aumento gradual en el nivel plasmático de progesterona y estrógenos, lo cual conlleva a un acúmulo anormal de bacterias, lo que genera esta enfermedad conocida como gingivitis. Dicha entidad presenta una prevalencia que oscila entre el 35 al 100 %. Consideraciones finales: Si la gingivitis no es tratada durante los dos primeros trimestres las bacterias pueden migrar al torrente sanguíneo y fijarse en la placenta. El cuerpo, como mecanismo de defensa para salvar al bebé entra en trabajo de parto, lo que provoca un parto prematuro. Por este hecho es indispensable asistir a los controles odontológicos.


Introduction: Pregnancy is a time of change for women. Changes occur throughout the body due to increased levels of the hormone progesterone. The gingiva is a key tissue for the action of steroid hormones, for this reason clinical changes in periodontal tissues are identified during periods of hormonal fluctuation. Objective: To systematize aspects of what gingivitis in pregnancy is, what its causes and consequences are, and how to treat it safely for the mother and baby. Method: Bibliographic reviews were carried out where the manifestations of periodontal disease during pregnancy could be addressed and interpreted. 20 scientific articles from national and international journals in both Spanish and Portuguese from the last 5 years (2018-2022) were examined; Of the 20 articles, 5 were excluded, since they did not coincide with the topic investigated. Results: The effects of estrogen and progesterone on the periodontium have been the subject of attention by researchers over the years. For this reason, women's periodontal tissues are more susceptible to this pathology during pregnancy due to the gradual increase in the plasma level of progesterone and estrogen, which leads to an abnormal accumulation of bacteria, which generates this disease known as gingivitis. This entity has a prevalence that ranges between 35 to 100%. Final considerations: If gingivitis is not treated during the first two trimesters, bacteria can migrate into the bloodstream and settle in the placenta. The body, as a defense mechanism to save the baby, goes into labor, which causes premature birth. For this reason, it is essential to attend dental check-ups.


Introdução: A gravidez é um momento de mudanças para a mulher. Mudanças ocorrem em todo o corpo devido ao aumento dos níveis do hormônio progesterona. A gengiva é um tecido fundamental para a ação dos hormônios esteróides, por esta razão são identificadas alterações clínicas nos tecidos periodontais durante períodos de flutuação hormonal. Objetivo: Sistematizar aspectos do que é gengivite na gravidez, quais são suas causas e consequências e como tratá-la com segurança para a mãe e o bebê. Método: Foram realizadas revisões bibliográficas onde puderam ser abordadas e interpretadas as manifestações da doença periodontal durante a gravidez. Foram examinados 20 artigos científicos de revistas nacionais e internacionais em espanhol e português dos últimos 5 anos (2018-2022); Dos 20 artigos, 5 foram excluídos, por não coincidirem com o tema investigado. Resultados: Os efeitos do estrogênio e da progesterona sobre o periodonto têm sido objeto de atenção de pesquisadores ao longo dos anos. Por este motivo, os tecidos periodontais das mulheres são mais suscetíveis a esta patologia durante a gravidez devido ao aumento gradual do nível plasmático de progesterona e estrogênio, o que leva a um acúmulo anormal de bactérias, o que gera esta doença conhecida como gengivite. Esta entidade tem uma prevalência que varia entre 35 a 100%. Considerações finais: Se a gengivite não for tratada nos dois primeiros trimestres, as bactérias podem migrar para a corrente sanguínea e se instalar na placenta. O corpo, como mecanismo de defesa para salvar o bebê, entra em trabalho de parto, o que provoca o nascimento prematuro. Por esse motivo, é imprescindível a realização de exames odontológicos.

RESUMO

Introducción: Las enfermedades periodontales inmunoinflamatorias crónicas, están catalogadas entre las afecciones más comunes del género humano, las que pueden estar asociadas a enfermedades sistémicas como la artritis reumatoidea. Objetivo: Identificar las manifestaciones periodontales más comunes en pacientes con artritis reumatoidea. Métodos: Se realizó un estudio observacional descriptivo de corte transversal. El universo estuvo constituido por 107 pacientes con diagnóstico de artritis reumatoidea, la muestra no probabilística de 50 pacientes que acudieron a consulta estomatológica durante el periodo, que cumplieron con los criterios de inclusión y exclusión previstos en el estudio. Las principales variables estudiadas fueron: edad, sexo, tiempo de diagnóstico de artritis reumatoide, presencia de enfermedad periodontal (gingivitis y periodontitis), factores de riesgo. Resultados: Prevaleció las edades entre 49 a 58 años, seguido de 39 a 48 años para un 34 y 26 % respectivamente, predominó el sexo femenino con un 46 % de afectadas por gingivitis y con más de siete años para un 58 %, la higiene bucal deficiente seguido de la dieta cariogénica prevaleció en un 50 % y 54% respectivamente. Conclusiones: Predominó el sexo femenino de pacientes diagnosticadas con artritis reumatoidea afectadas por gingivitis, ambas enfermedades son inflamatorias sistémicas, por lo que se puede explicar la conexión entre las dos.


Introduction: Chronic immunoinflammatory periodontal diseases are classified among the most common affections of the human gender, which may be associated with systemic diseases such as rheumatoid arthritis. Objective: To identify the most common periodontal manifestations in patients with rheumatoid arthritis. Methods: A cross-sectional descriptive observational study was carried out. The universe consisted of 107 patients diagnosed with rheumatoid arthritis, the non-probabilistic sample of 50 patients who attended a dental consultation during the study period, who met the inclusion and exclusion criteria provided for in the study. The main variables studied were: age, sex, time since diagnosis of rheumatoid arthritis, presence of periodontal disease (gingivitis and periodontitis), risk factors. Results: Ages between 49 and 58 years prevailed, followed by 39 to 48 years with 34 and 26% respectively, predominantly female with 46% affected by gingivitis, affected with more than 7 years with 58%, the poor oral hygiene followed by the cariogenic diet prevailed with 54 and 50% respectively. Conclusions: The female sex prevailed in patients diagnosed with rheumatoid arthritis affected by gingivitis, both diseases are systemic inflammatory, so the connection between the two can be explained.

RESUMO

Objective: Chewable toothbrushes (CT) are considered an effective tool for dental plaque removal; however, their effectiveness is still uncertain compared to Manual toothbrushes (MT). Aim: To evaluate the effectiveness of CT compared to MT in dental plaque removal. Methods: Studies comparing the efficiency of CT and MT in dental plaque removal measured by Turesky Modification of Quigley-Hein Plaque Index (TMQHI), Quigley-Hein Plaque Index (QHI), or Silness Loe Plaque Index (SLPI) were identified in PubMed, Medline Web of Science, Google Scholar, and the CENTRAL. Results and effect sizes estimate are presented as mean difference, and subgroup analysis is presented separately for non?randomised interventional studies and randomised intervention studies. Risk of bias was assessed using the Cochrane risk of bias tool (ROBINS?I and ROB2 tool). Results: A total of 10 studies were included in the systematic review, whereas six out of 10 studies were included in the meta?analysis. Both CT and MT were effective in plaque reduction over time when compared individually using the TMQHI and SLPI scores. The overall pooled summary showed no difference in CT and MT’s dental plaque removal ability when measured using the TMQHI score. Similarly, there was no difference in CT and MT’s dental plaque removal ability when measured using the SLPI score. Conclusion: There is no significant difference in CT and MT’s plaque removal ability. Therefore, CT should only be recommended for children and individuals with a disability or manual dexterity.

RESUMO

Resumen En la cavidad oral se pueden presentar lesiones en gíngiva que no están asociadas a placa bacteriana, las cuales requieren de un adecuado diagnóstico y tratamiento. La gingivitis descamativa está usualmente relacionada con desórdenes mucocutáneos, como el pénfigo vulgar (PV), donde las lesiones orales incluyendo las lesiones gingivales, pueden preceder las lesiones cutáneas. El manejo es multidisciplinario y el tratamiento incluye terapia farmacológica tópica y sistémica, se requiere un adecuado control de la placa bacteriana por parte del paciente y una estricta supervisión en el tiempo por parte del profesional para el mantenimiento y estabilidad de los tejidos gingivales. Se presentan dos casos clínicos de pacientes con diagnóstico de PV los cuales fueron manejados de manera oportuna e integral para controlar y estabilizar el factor sistémico y local.


Abstract In the oral cavity, gingiva lesions may occur that are not associated with bacterial plaque, which require adequate diagnosis and treatment. Desquamative gingivitis is usually related to mucocutaneous disorders, such as pemphigus vulgaris (PV), where oral lesions, including gingival lesions, may precede skin lesions. Management is multidisciplinary and treatment includes topical and systemic pharmacological therapy, require adequate control of dental plaque by the patient and strict supervision over time by the professional for the maintenance and stability of the gingival tissues. Two clinical cases of patients with a diagnosis of PV are presented, which were managed in a timely and integral way to control and stabilize the systemic and local factor.

RESUMO

Abstract The objective of this study was to determine the gingival state and presence of red complex bacteria in saliva samples of 12-year-old schoolchildren. A calibrated periodontist evaluated biofilm index (BI) (Silness and Löe, 1964), presence of calculus, and gingival index (GI) (Silness and Löe, 1967) in sixty two 12-year-old students of Carmen Lyra School. Saliva samples were collected from each student. The DNA of each sample was extracted and amplified by the polymerase chain reaction (PCR) technique, using specific primers. The BI was 1.18. Calculus was present in 40.40% of the schoolchildren examined; 19.4% was supragingival calculus and 21% both supragingival and subgingival calculus. The GI was 0.97, which according to Silness and Löe is mild gingivitis. Gingivitis was present in 96.8% of the children examined. Regarding the PCR tests: 18 of the samples (31.58%) did not present any of the bacteria analyzed and the remaining 39 samples (68.42%) were positive for at least the presence of red complex bacteria. Within the limitations of this study, it is concluded that the prevalence of gingivitis and calculus is high in the sample examined, and the gingival state observed in the study population, may be related to the presence of red complex bacteria.


Resumen El objetivo de este estudio era determinar el estado gingival y la presencia de bacterias del complejo rojo en muestras de saliva de niños de 12 años de la Escuela Carmen Lyra. Una periodoncista calibrada evaluó en 62 estudiantes de 12 años de la Escuela Carmen Lyra, el índice de biofilme (IB) (Silness y Löe, 1964), la presencia de cálculo y el índice gingival (IG) (Silness y Löe, 1967). Se recolectaron muestras de saliva de cada estudiante. El ADN de cada muestra fue extraído y amplificado por medio de la prueba PCR, empleando primers específicos, para determinar la presencia de bacterias del complejo rojo. El IB fue de 1.18. El cálculo estuvo presente en el 40.40% de la muestra, se encontró 19.4% de cálculo en supragingival y 21% tanto en supragingival como en subgingival. El IG fue de 0.97, que de acuerdo con Silness y Löe es una gingivitis leve. La gingivitis estuvo presente en el 96.8 % de los niños examinados. Con respecto a las pruebas PCR: 18 de las muestras (31.58 %) no presentaron ninguna de las bacterias analizadas y las 39 muestras restantes (68.42%) fueron positivas por lo menos a la presencia de las bacterias del complejo rojo. Dentro de las limitaciones de este estudio, se concluye que la prevalencia de gingivitis y cálculo es alta en la muestra examinada y el estado gingival observado puede estar relacionado con la presencia de bacterias del complejo rojo.

RESUMO

Resumen La enfermedad periodontal (gingivitis y periodontitis) es un proceso inflamatorio ocasionado por la actividad de bacterias patógenas y sus productos sobre el surco gingival, con la consecuente activación de la respuesta inmunitaria. La saliva y el fluido crevicular contienen una gran variedad de enzimas y factores antimicrobianos que están en contacto con la región supragingival y subgingival; entre ellos, las β-defensinas (hBDs). Las hBDs son péptidos catiónicos no glicosilados ricos en cisteína, producidos por las células epiteliales; tienen efecto antimicrobiano e inmunorregulador; de esta forma, contribuyen al mantenimiento de la homeostasis en los tejidos periodontales. Los cambios en la microbiota y en la respuesta inmunitaria de un periodonto sano a gingivitis y, finalmente, a periodontitis, es compleja. Su severidad depende de un equilibrio dinámico entre las bacterias asociadas a la placa, factores genéticos y ambientales. Los avances recientes han permitido comprender la implicación de las hBDs en la detección, el diagnóstico y la terapéutica de la enfermedad periodontal, así como la relación que hay entre la periodontitis y otras enfermedades inflamatorias. El objetivo de esta revisión es describir el efecto de las hBDs en la respuesta inmunitaria y su utilización como marcadores de la actividad inflamatoria de la enfermedad periodontal.


Abstract Periodontal disease (gingivitis and periodontitis) is an inflammatory process caused by the activity of pathogenic bacteria and their products on the gingival sulcus, with the consequent activation of the immune response. Saliva and crevicular fluid contain a wide variety of enzymes and antimicrobial factors that are in contact with the supragingival and subgingival region, including β-defensins (hBDs). hHBDs are non-glycosylated, cysteine-rich cationic peptides produced by epithelial cells with antimicrobial and immunoregulatory effects, thus contributing to maintaining homeostasis in periodontal tissues. The changes in the microbiota and the immune response from a healthy periodontium to gingivitis and, finally, to periodontitis are complex. Their severity depends on a dynamic balance between bacteria associated with plaque, genetic and environmental factors. Recent advances have made it possible to understand the implication of hBDs in the detection, diagnosis, and therapy of periodontal disease and the relationship between periodontitis and other inflammatory conditions. This review aims to describe the effect of hBDs on the immune response and its use as a possible marker of the inflammatory activity of the periodontal disease.
