Association between oral health-related quality of life and symptoms of temporomandibular disorder among older adults: A cross-sectional study.

OBJECTIVE: Evaluate the association between oral health-related quality of life (OHRQoL) and self-reported symptoms of TMD. METHODS: Representative samples of older adults (≥60 years) were included (n = 569). Both TMD symptoms and OHRQoL were assessed by Fonseca Anamnestic Index (FAI) and Oral Health Impact Profile-14 (OHIP-14), respectively. Prevalence (those answering "frequently" or "always" in at least one question), severity (total means scores), and extent (number of questions answered as "frequently" or "always") of OHRQoL were estimated. RESULTS: Overall, 33.4% and 9.5% had mild or moderate/severe TMD symptoms. Those with any symptom of TMD had a prevalence ratio (PR) 38% higher for the worst OHRQoL (95% confidence interval [95%CI]:1.04-1.82) compared to those without TMD symptoms. Worst OHRQoL were observed for those with mild (PR:1.35; 95%CI:1.01-1.81) and moderate/severe TMD (PR:1.53; 95%CI:1.04-2.26). Similar results were detected in the severity and extent of OHRQoL. CONCLUSION: Severity TMD was associated with worse ORHQoL.

Influence of angiotensin receptor and converting enzyme blockers therapy in the respiratory outcome of COVID-19 hospitalized patients / Influencia de la terapia con bloqueadores del receptor de angiotensina y de la enzima convertidora en el resultado respiratorio de pacientes hospitalizados por COVID-19

Objectives: COVID-19, caused by SARS-CoV-2, has spread around the world since 2019. In severe cases, COVID-19 can lead to hospitalization and death. Systemic arterial hypertension and other comorbidities are associated with serious COVID-19 infection. Literature is unclear whether antihypertensive therapy with angiotensin receptor blockers (ARBs) and angiotensin converting enzyme (ACE) inhibitors affect COVID-19 outcomes. We aim to assess whether ACEI/ARB therapy is a risk factor for worse respiratory outcomes related to COVID-19 in hospitalized patients. Methods: Retrospective study enrolling admitted COVID-19-diagnosed patients by RT-PCR at the Hospital Geral de Fortaleza, Brazil, during 2021. Patient medical records, sociodemographic, and clinical data were analyzed. Chest CT images were analyzed using CAD4COVID-CT/Thirona™ software. Results: A total of 294 patients took part in the study. A cut-off point of 66% of pulmonary involvement was found by ROC curve, with patients having higher risk of death and intubation and lower 60-day survival. Advanced age (RR 1.025, P=0.001) and intubation (RR 16.747, P<0.001) were significantly associated with a higher risk of death. Advanced age (RR 1.023, P=0.001) and the use of noninvasive ventilation (RR 1.548, P=0.037) were associated with a higher risk of intubation. Lung involvement (>66%) increased the risk of death by almost 2.5-fold (RR 2.439, P<0.001) and by more than 2.3-fold the risk of intubation (RR 2.317, P<0.001). Conclusions: Altogether, our findings suggest that ACEI or ARB therapy does not affect the risk of death and disease course during hospitalization.(AU)

Objetivos: La COVID-19, causada por el SARS-CoV-2, se ha extendido por todo el mundo desde 2019. En casos graves, la COVID-19 puede provocar hospitalización y muerte. La hipertensión arterial sistémica y otras comorbilidades se asocian con una infección grave por COVID-19. La literatura no está clara si la terapia antihipertensiva con bloqueadores de los receptores de angiotensina (BRA) e inhibidores de la enzima convertidora de angiotensina (ECA) afecta los resultados de la COVID-19. Nuestro objetivo fue evaluar si la terapia BRA/ECA es un factor de riesgo de peores resultados respiratorios relacionados con COVID-19 en pacientes hospitalizados. Métodos: Estudio retrospectivo que incluyó pacientes ingresados con diagnóstico de COVID-19 mediante RT-PCR en el Hospital General de Fortaleza, Brasil, durante 2021. Se analizaron las historias clínicas de los pacientes, datos sociodemográficos y clínicos. Las imágenes de TC de tórax se analizaron utilizando el software CAD4COVID-CT/ThironaTM. Resultados: Participaron en el estudio un total de 294 pacientes. Mediante curva ROC se encontró un punto de corte del 66% de afectación pulmonar, teniendo los pacientes mayor riesgo de muerte e intubación y menor supervivencia a 60 días. La edad avanzada (RR 1,025; P=0,001) y la intubación (RR 16,747; P<0,001) se asociaron significativamente con un mayor riesgo de muerte. La edad avanzada (RR 1,023; P=0,001) y el uso de ventilación no invasiva (RR 1,548; P=0,037) se asociaron con un mayor riesgo de intubación. La afectación pulmonar (>66%) aumentó el riesgo de muerte casi 2,5 veces (RR 2,439; P<0,001) y más de 2,3 veces el riesgo de intubación (RR 2,317, P<0,001). Conclusiones: Se concluyó que el tratamiento con BRA o ECA no afecta el riesgo de muerte y el curso de la enfermedad durante la hospitalización.(AU)

Association between salivary flow and dental caries in institutionalized adolescents: Cross-sectional study.

Background: Brazil has a larger number of adolescent offenders, but studies evaluating their oral health are still limited. Objective: Assess the association between salivary flow and caries experience in youngsters deprived of liberty. Methodology: Sixty-eight male adolescents in conflict with the law, aged between 15 and 19 years, from a Socio-Educational Assistance Center in Brazil participated in the present study. They answered a structured questionnaire, and oral examination was performed by the Decayed, Missing, and Filled Teeth (DMFT) index. The salivary flow rate was obtained using the mechanically stimulated total saliva method. Adjusted Poisson regression was used for the association with total DMFT and its decayed component, using the salivary flow (continuous fashion) or the hyposalivation (≤1 ml/min) as independent variables. Results: Participants were divided into two groups, those who did not have any decayed teeth at the moment of the examination (n = 39) and those who had at least one decayed tooth (n = 29). Moreover, two groups were formed based on the DMFT: those who had DMFT = 0 (n = 20) and those who had DMFT≥1 (n = 48). In the multivariate analysis, hyposalivation was associated with DMFT≥1 (p = 0.048), but when the salivary flow was included, no significant association with DMFT index was identified (p = 0.178). Conversely, the presence of at least one decayed tooth was significantly associated with the salivary flow (p = 0.004), but not with hyposalivation (p = 0.091). Conclusions: Institutionalized adolescents who present hyposalivation or low salivary flow are associated with DMFT≥1 index or presence of at least one decayed tooth, respectively.

CONCLUSIONS: Altogether, our findings suggest that ACEI or ARB therapy does not affect the risk of death and disease course during hospitalization.

Association between sequelae of COVID-19 with periodontal disease and obesity: A cross-sectional study.

BACKGROUND: To assess the sequelae of coronavirus disease 2019 (COVID-19) and associated factors, such as obesity and periodontitis in adults. METHODS: The study included 128 individuals aged ≥35 years with a history of a diagnosis of COVID-19 through real-time polymerase chain reaction (RT-PCR), from Pelotas, Brazil. Self-report sequelae from COVID-19 were defined as the primary outcome. A questionnaire containing sociodemographic, medical, behavioral and self-report of sequelae of COVID-19 was applied. A complete periodontal clinical examination was performed. Weight and height were assessed. Uni-, bi- and multivariate analyses were performed using Poisson regression with robust variance. Additional analyses were performed considering obesity as a subgroup. RESULTS: When considering the whole sample, no statistically significant associations between sequelae of COVID-19 with periodontitis (prevalence ratio [PR]:1.14;95% confidence interval [95%CI]: 0.80-1.61) and obesity (0.93 [0.68-1.26]) were identified. In the subgroup analysis, considering only individuals with obesity, those diagnosed with generalized periodontitis had 86% higher probability to have sequelae of COVID-19 when compared to individuals with periodontal health or localized periodontitis. However, when only those without obesity were considered, no significant association with periodontal status was detected (0.82 [0.55-1.23). No significant association with periodontal status were observed when the severity of sequelae (no sequelae, 1 sequela, and >1 sequela) were considered (p > 0.05). CONCLUSIONS: Individuals diagnosed with obesity and periodontitis have a higher PR of reporting sequelae from COVID-19 compared to individuals with only obesity.

Association between dental environment stress and sense of coherence in dental students: a cross-sectional study.

The aim of this study was to explore associated variables with sense of coherence (SOC), and dental environment stress (DES) in a sample of dental students. All undergraduate (n = 474) and graduate (n = 105) dental students enrolled in the first semester of 2020 at a public university in southern Brazil were invited to participate. Data collection was performed by an online questionnaire, which included information related to sociodemographic and educational characteristics, biopsychosocial factors, aspects related to feelings experienced in the COVID-19 pandemic, and the SOC scale. The study outcome (DES) was measured by a validated tool. Linear regression analyses were performed to identify the associations between the outcome and all independent variables. A total of 408 students were included (response rate: 70.5%). The overall mean score of the DES scale was 73.95 (SD: 24.13). Students with higher SOC scores were observed to have significantly lower DES scores (ßGRADUATE: -0.376; 95%: -0.482 to -0.271; ßUNDERGRADUATE: -0.478; 95%:-0.658 to -0.297). Female undergraduate students (ß: 11.788; 95%CI: 7.161-16.415) had higher DES scores compared with undergraduate male students. In addition, the presence of anxiety symptoms when providing dental care to patients with symptoms or suspected COVID-19 infection was associated with higher DES scores (ß: 10.460; 95%CI: 5.644-15.277) among undergraduate dental students. The level of stress was higher in non-white undergraduate students than white (ß: 8.912; 95%CI: 3.581-14.244). Among both undergraduate and graduate dental students, higher SOC scores were associated with lower DES.

Xenogeneic collagen matrix vs. connective tissue graft for the treatment of multiple gingival recession: a systematic review and meta-analysis.

The aim of this systematic review (SR) compared the effect of xenogeneic collagen matrix (XCM) vs. connective tissue graft (CTG) for the treatment of multiple gingival recession (MGR) Miller Class I and II or Cairo type I. Five databases were searched up to August 2022 for randomized clinical trials (RCTs) comparing the clinical effects of XCM vs. CTG in the treatment of MGR. The random effects model of mean differences was used to determine reduction of gingival recession (GR), gain in keratinized tissue width (KTW), gain in gingival thickness (GT) and gain in clinical attachment level (CAL). The risk ratio was used to complete root coverage (CRC) at 6 and 12 months. 10 RCTs, representing 1095 and 649 GR at 6 and 12 months, respectively, were included in this SR. The meta-analysis showed no statistically significant difference in GR reduction, KTW gain GT gain or CAL gain between groups at 6 months. However, at 12 months of follow-up, differences favoring the control group were observed (p < 0.05). CRC was significantly higher in the CTG group at 6 and 12 months. Regarding dentine hypersensitivity (DH), no statistically significant differences were found between groups at 6 and 12 months of follow-up (p < 0.05). At 12 months, CTG showed significantly superior clinical results in the treatment of MGR: however, this difference was not observed in the decrease of DH.

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)

Tratamento de periodontite estágio III localizado grau C em um indivíduo fumante: um relato de caso / Treatment of periodontitis stage III localized grade C in smoker individual: a case report

Objetivo: A periodontite é uma doença infecto-inflamatória que acomete os tecidos de inserção periodontal, e ser fumante representa um risco modificável significativo para todos os graus da doença. Ainda, indivíduos fumantes apresentam uma resposta inflamatória alterada quando comparados a não fumantes. Nesse contexto, o objetivo deste estudo foi reportar um relato de caso de tratamento periodontal de paciente fumante pesado. Relato de caso: O paciente DRS, sexo masculino, 22 anos, foi encaminhado à Faculdade de Odontologia da Universidade Federal de Pelotas (UFPel) com a queixa principal de necessidade de "realização de uma limpeza dentária". Na anamnese, relatou fumar 20 cigarros ao dia, há 7 anos (7 maços-ano). Na consulta inicial, foi encontrado índice de placa visível (IPV) de 100% e índice de sangramento gengival (ISG) de 66,67%. Foi encontrado cálculo supragengival como fator retentivo de placa (FRP) em 46,30% dos sítios. Estabeleceu-se o diagnóstico de periodontite estágio III localizado grau C. Os exames periodontais foram realizados por um único pesquisador calibrado e optou-se pelo tratamento periodontal não cirúrgico. Ao exame de 12 meses, o paciente apresentou IPV de 23,45% e ISG de 22,83%. Houve ausência de FRP. De uma forma geral, foi possível constatar a diminuição significativa das bolsas periodontais, bem como o ganho significativo de inserção clínica periodontal. Considerações finais: Dessa forma, é possível concluir a efetividade da terapia periodontal não cirúrgica, aliada à manutenção periodontal e instruções de higiene para o tratamento de periodontite estágio III, grau C, em paciente fumante.(AU)

Objective: Periodontitis is an infect-inflammatory diseases that affects the periodontal attachment tissues, and being smoker represents a significant modifiable risk for all degrees of the disease. Moreover, smokers have an altered inflammatory response when compared to non-smokers. Therefore, the aim of this study was to report a case report of periodontal treatment of a heavy smoker. Case report: A patient DRS, male, 22 years old, was referred to the School of Dentistry of the Federal University of Pelotas (UFPel) with the main complaint of the need to "perform a dental cleaning". During the anamnesis, he reported smoking 20 cigarettes a day for 7 years (7 pack-years). In the initial appointment, a visible plaque index (VPI) of 100% and a gingival bleeding index (GBI) of 66.67% were found. Supragingival calculus was found as a plaque retentive factor (PRF) in 46.30% of the sites. The diagnosis of periodontitis stage III localized grade C was established. Periodontal examinations were performed by a single calibrated researcher and non-surgical periodontal treatment was chosen. At the 12-month appointment, the patient had an VPI of 23.45% and an GBI of 22.83%. There was absence of PRF. In general, it was possible to observe a significant decrease in periodontal pockets, as well as a significant gain in periodontal clinical attachment. Final considerations: Thus, it is possible to conclude the effectiveness of non-surgical periodontal therapy, combined with periodontal maintenance and hygiene instructions for the treatment of periodontitis stage III localized grade C in a smoker.(AU)

Association between history of academic failure during dental school and self-reported depression, anxiety, and stress: A retrospective cohort.

OBJECTIVE: To investigate the association between history of academic failure (HAF) and self-reported depression, anxiety, and stress among undergraduate dental students. METHODS: This study involved 244 dental students from one university. An online questionnaire collected information on the following variables: socioeconomic status, behavior, use of licit/illicit drugs, and the choice of dentistry as an undergraduate field of study. The 21-item Depression Anxiety Stress Scale (DASS-21) was applied. HAF in at least one subject during a participant's undergraduate tenure was defined as the main outcome. Bivariate and multivariate analyses were performed using Poisson regression with robust variance. In addition, a subgroup analysis was performed for the variable "dentistry as the first choice for undergraduate studies." RESULTS: The prevalence of HAF was 25.00% (n = 61). Among those students, the mean number of academic failures was 5.41 ± 6.38 (range: 1-33). Higher rates of HAF were observed among older and non-white dental students. Moreover, those who self-reported at least severe depression presented a 79% higher HAF prevalence ratio (PR) (95% confidence interval [95% CI]: 1.15-2.80). Similar findings were detected among those who reported (PR: 1.79; 95% CI: 1.06-4.46) or did not report (PR: 2.21; 95% CI: 1.10-4.46) interest in dentistry as a first undergraduate option. Conversely, among women and students who did not choose dentistry as their first option, HAF was significantly lower (PR: 0.41; 95% CI: 0.21-0.80). CONCLUSION: Higher HAF rates are observed in students who are older, non-white, and self-report at least severe depression. However, dentistry as a first option for undergraduate studies was not associated with HAF.

Is there an association between dental caries and genetics? Systematic review and meta-analysis of studies with twins.

OBJECTIVE: This review aimed to assess the agreement of dental caries experience between monozygotic (MZ) and dizygotic (DZ) twins. DATA RESOURCES: This systematic review was performed by reviewers in the databases Embase, MEDLINE-PubMed, Scopus, Web of Science and manual searches and gray literature Google Scholar® and Opengray. Observational studies that evaluated dental caries in twins were included. The risk of bias was analyzed using the Joanna Briggs checklist. Meta-analyses were performed to assess the pooled Odds Ratio to estimate the agreement values of dental caries experience and DMF index between pairs of twins (p < 0.05). To assess the certainty of evidence, the GRADE scale was used. STUDY SELECTION: 2533 studies were identified, of which 19 were included in the qualitative analysis, six in the quantitative synthesis, with two meta-analyses being carried out. Association between genetics and the development of the disease was observed in most studies. In the risk of bias analysis, 47.4% had moderate risk. Higher agreement of dental caries experience was observed in MZ twins than DZ in both dentitions (OR: 5.94; 95% CI: 2.00-17.57). However, there was no difference between the MZ and DZ twin groups in the analysis comparing DMF index agreement (OR: 2.86; 95%CI: 0.25-32.79). The certainty of evidence was considered low and very low for all studies included in meta-analyses. CONCLUSION: With very low certainty of the evidence, the genetic factor seems to influence the agreement of the caries experience. CLINICAL RELEVANCE: Understanding the genetic influence on the disease has the potential to contribute to the development of studies that may use biotechnologies for prevention and treatment as well as guide future research involving gene therapies aiming to prevent the occurrence of dental caries.

Effect of collagen sponge and flowable resin composite on pain management after free gingival graft harvesting: A randomized controlled clinical trial.

The aim of this study was to compare the effect of the application of a flowable resin composite coating, over a collagen sponge stabilized with suture, on postoperative pain after free gingival graft harvesting. Thirty-two free gingival grafts were harvested from the palate in 32 patients, who were subsequently randomized to have only a collagen sponge stabilized with sutures applied to the palatal wound (control), or to have the collagen sponge coated with a flowable resin composite (test). Patients were observed for 14 days, and the pain level was evaluated by using a numerical rating scale. The consumption of analgesics during the postoperative period and the characteristic of the graft were also analyzed. The patients in the test group reported having experienced significantly less pain statistically than the patients in the control group throughout the study. The consumption of analgesics was lower in the test group. The dimensions of harvested grafts in the control and test groups showed no significant differences in height, width, and thickness. In conclusion, the addition of flowable resin composite coating to the hemostatic collagen sponge on the palatal wound following free gingival graft harvesting helped to minimize postoperative pain.

Effect of mouthwashes on gingival healing after surgical procedures: A systematic review.

The aim of the present study was to perform a systematic review of the literature regarding the effect of different mouthwashes on gingival healing after oral surgery in adults. Searches were conducted in seven databases (PubMed/MEDLINE, Cochrane Library, Clinical Trials Registry, Embase, LILACS, Web of Science, and Google Scholar) for relevant randomized controlled trials (RCTs) published up to April 2022. The selection of studies, data extraction, and risk of bias appraisal were performed independently by two reviewers, and a third researcher was consulted to resolve disagreements. Data syntheses were presented narratively for the different criteria of gingival wound healing. Among 4502 articles retrieved from the databases, 13 studies met the eligibility criteria and were included in the present review. Chlorhexidine was the most frequent mouthwash studied (eight studies) and was used in different concentrations and combinations. Cetylpyridinium chloride, H2 Ocean Sea Salt, Commiphora molmol 0.5%, chlorhexidine 0.12%, and essential oils reported better healing than a negative control. However, the uncertain risk of bias in most RCTs included in this review precludes definitive conclusions. Well-designed RCTs are therefore still needed in this area.

Associação do desempenho acadêmico com estresse, ansiedade e depressão em estudantes de graduação em Odontologia: estudo transversal / Asociación del rendimiento académico con el estrés, la ansiedad y la depresión en estudiantes de pregrado en odontología: estudio transversal / Association between academic performance with stress, anxiety and depression among undergraduate dental students: across-sectional study

O estudo objetivou analisar a associação entre o desempenho acadêmico e a prevalência autorrelatada de ansiedade, depressão e estresse em alunos de graduação em Odontologia de uma universidade pública brasileira.Os estudantes participaram da pesquisa por meio de um questionário disponibilizado no Google Forms,contemplando variáveis exploratórias, como idade, sexo, cor da pele, uso de ansiolíticos ou antidepressivos e atividades remuneradas. A escala traduzida e adaptada "Depression, Anxiety and Stress Scale-21" (DASS-21) foi utilizada para aferir os sintomas de ansiedade, estresse e depressão. O desempenho acadêmico foi quantificado como baixo para notas <7 pontos e bom para≥7 pontos, considerando a média geral do estudante. Regressões logísticas foram realizadas para verificar a razão de chance entre desempenho acadêmico e os domínios da escala DASS-21. Foram feitas, também análises de subgrupo comparando o sexo dos estudantes (p<0,05).A amostra final avaliou 244 estudantes. Foi observado que os estudantes com depressão moderada apresentaram maior chance de terem baixo rendimento acadêmico, quando comparados com aqueles com depressão normal ou leve (RC:2,41; IC95%:1,10-5,29). Na análise de subgrupo foi demonstrado que, somente ao se considerar o sexo masculino, aqueles com depressão pelo menos moderada apresentaram maior chance de baixo rendimento acadêmico (RC:4,10; IC95%:1,19-14,19).O baixo rendimento acadêmico esteve significativamente associado aos estudantes comdepressão pelo menos moderada. Além disso, indivíduos do sexo masculino com depressão pelo menos moderada apresentaram maior ocorrência de baixo desempenho acadêmico (AU).

El estudio tuvo como objetivo analizar la asociación entre el rendimiento académico y la prevalencia autorreportada de la ansiedad, la depresión y el estrés en estudiantes de pregrado en odontología de una universidad pública brasileña. Los estudiantes participaron en la investigación a través de un cuestionario disponible en Google Forms, que contemplaba variables exploratorias como la edad, sexo, color de piel, uso de ansiolíticos o antidepresivos y actividades remuneradas. Para medir los síntomasde ansiedad, estrés y depresión se utilizó la escala traducida y adaptada "Depression, Anxiety and Stress Scale-21" (DASS-21). El rendimiento académico se cuantificó como bajo para calificaciones <7 puntos y bueno para ≥7 puntos, considerando el promedio general del estudiante. Se realizaron regresiones logísticas para verificar la razón de posibilidades entre el rendimiento académico y los dominios de la escala DASS-21. También se realizaron análisis de subgrupos comparando el sexo de los estudiantes (p<0,05). La muestra final evaluó a 244 estudiantes. Se observó que los estudiantes con depresión moderada tenían mayor probabilidad de tener bajo rendimiento académico, en comparación con aquellos con depresión normal o leve (OR:2,41; IC95%:1,10-5,29). En el análisis de subgrupos se demostró que, considerando solo el sexo masculino, aquellos con depresión al menos moderada tenían mayor probabilidad de bajo rendimiento académico (OR:4.10; IC95%:1.19-14.19). El bajo rendimiento académico se asoció significativamente con estudiantes con depresión al menos moderada. Además, los individuos del sexo masculino con depresión al menos moderada tuvieron una mayor incidencia de bajo rendimiento académico (AU).

This study analyzed the association between academic performance and self-reported anxiety, depression and stress among undergraduate dental students at a Brazilian public university. Students participated via a questionnaire, available on Google Forms, which involved exploratory variables such as age, sex, ethnicity/skin color, use of anxiolytics or antidepressants and remunerated activities. The translated and adapted Depression, Anxiety and Stress Scale-21 (DASS-21) was used to measure participants' symptoms of anxiety, stress and depression. Academic performance was quantified as "poor" for grades <7 points or "good" for ≥7 points, referring to the student's overall average. Logistic regressions were performed to verify the odds ratio (OR) between academic performance and the domains of the DASS-21. Subgroup analyses were also performed to compare the sex of the participants (p<0.05). The final sample evaluated 244 students. It was observed that students with moderate depression were more likely to exhibit poor academic performance when compared to those with normal or mild depression (OR:2.41; 95%CI:1.10­5.29). The subgroup analysis demonstrated that male participants with at least moderate depression had a greater chance of poor academic performance (OR:4.10;95%CI:1.19­14.19). Poor academic performance was significantly associated with students with at least moderate depression. In addition, male individuals with at least moderate depression had a higher occurrence of poor academic performance (AU).

Influence of graft thickness on tunnel technique procedures for root coverage: a pilot split-mouth randomized controlled trial.

OBJECTIVE: To compare the clinical outcomes of the tunnel technique (TUN) combined with either thin connective tissue graft (CTG) (TUN + thin CTG) (1 mm) or thick CTG (TUN + thick CTG) (2 mm) for the treatment of localized gingival recession (GR). MATERIAL AND METHODS: Twelve patients, with 24 maxillary localized type RT1 GR were randomly assigned into two groups. Clinical, esthetic, and patient-reported outcomes were evaluated at baseline and at 6-month follow-up. RESULTS: The TUN + thin CTG group showed a higher mean GR reduction (1.53 ± 0.66) (primary outcome variable) than the TUN + thick CTG group (1.44 ± 0.89), but no statistically significant difference was detected at the 6-month follow-up (p = 0.77). No statistically significant differences were found between TUN + thin CTG and TUN + thick CTG concerning complete root coverage (CRC) (58.3% versus 41.7%, respectively), gingival ticknness (GT) or Root-coverage Esthetic Score (RES) at 6 months. Regarding patient-reported outcomes, both groups reported having experienced similar pain at 7 days (p > 0.05). No statistically significant differences were found between the groups in the analysis of the aesthetic score. CONCLUSION: Both treatments showed a similar reduction in GR. In addition, similar CRC, GT, RES, pain and self-reported esthetics were achieved in both groups. CLINICAL RELEVANCE: Application of thin CTG provided a similar result than thick CTG for the treatment of RT1 localized GR.

Periodontal Ehlers-Danlos syndrome in early childhood: A case report of loss of deciduous teeth.

The aim of the present study is to report a case of periodontal Ehlers-Danlos syndrome (pEDS) in early childhood. A 3-year-old child, complaining of severe tooth mobility, gingival bleeding, and early loss of deciduous teeth sought the dental clinics. The patient was diagnosed with pEDS, and no other systematic health impairments were diagnosed. It was implemented a strict supragingival biofilm control, using mechanical and chemical strategies. However, during the treatment, the patient had to receive multiple dental extractions. Scaling and root planing were performed in the remaining teeth, and the patient is included in the periodontal maintenance program to prevent recurrence of the disease. It was concluded that, although rare, severe cases of periodontitis may occur in deciduous teeth. Strict supragingival biofilm control and periodontal maintenance are strongly recommended in those patients, along with familial monitoring.

Clinical efficacy of hyaluronic acid in the treatment of periodontal intrabony defect: a systematic review and meta-analysis.

OBJECTIVE: This systematic review aimed to evaluate the effects of hyaluronic acid (HA) alone or in combination with any bone substitute for the treatment of intrabony defects (IBDs). MATERIAL AND METHODS: Six databases were searched up to April 2022 to find randomized clinical trials comparing the clinical effects of open flap debridement (OFD) + HA versus OFD alone (first group) or OFD + HA + bone substitutes versus OFD + bone substitutes (second group) in the treatment of IBDs with a follow-up of at least 3 months. Random effects models of mean differences were used to determine the clinical attachment level (CAL) gain, probing depth (PD) reduction, and radiographic bone fill (RBF). RESULTS: Of the 276 studies identified, 6 were included in the qualitative synthesis, and 5 in the meta-analyses. The meta-analyses in the first group showed a statistically significant differences for CAL gain (mean difference [MD]:1.00; 95% confidence interval [CI]:0.65 - 1.35; n = 2) and PD reduction (MD: 0.76; 95%CI: 0.34 - 1.17; n = 2) favoring HA + OFD at 6 months. However, in the second group, the meta-analyses did no show additional effect of HA in association with bone substitute was demonstrated for either CAL gain (MD: 0.57; 95%CI: - 0.30 - 1.43; n = 2) or PD reduction (MD: 1.05; 95%CI: - 0.38 - 2.47; n = 2) but did show significant differences for RBF (MD: 0.57; 95%CI: 0.15 - 0.99; n = 2) at 12 months. CONCLUSION: Compared with OFD alone, local application of HA in the treatment of IBDs provided a significant CAL gain and PD reduction at 6 months. However, its combination with bone substitutes showed no statistically significant differences at 12 months. CLINICAL RELEVANCE: The use of OFD + HA improves the CAL and PD in the treatment of IBDs compared to OFD only after 6 months of follow-up. These results are not maintained after 12 months.

Poor Quality of Sleep is Associated with Lower Academic Performance in Undergraduate Dental Students: A Cross-Sectional Study.

Purpose: This study aimed to assess the quality of sleep and associated factors among dental students. Methods: All dental students regularly enrolled at the Federal University of Pelotas, Brazil, were invited to participate. A structured online questionnaire was applied to collect the independent variables, including academic performance. Quality of sleep was assessed by the validated version of the Pittsburgh Sleep Quality Index. Sample was dichotomized as good sleep quality (total score: ≤ 4) and at least poor quality (total score: ≥ 5). Adjusted analyses were performed using Poisson regression with robust variance to detect the association between sleep quality and independent variables. Independent adjusted models were performed to the whole-sample, only undergraduate and only graduate dental students. Results: Poor quality of sleep was detected in 266 (65.2%) dental students, of which 228 (68.9%) and 38 (49.4%) were undergraduate and graduate dental students, respectively. Female students presented a prevalence ratio (PR) 19% higher compared to males (95% confidence interval [CI] 1.01-1.41). When only graduate students were considering, those that reported not being the head of the family presented a PR 4.39 higher for poor quality of sleep (95% CI 1.91-10.09). Poor quality of sleep was associated with lower academic performance among undergraduate students (PR: 0.94; 95% CI 0.89-0.99), but not significantly associated when graduate students are considered (PR: 0.99; 95% CI 0.96-1.03). Conclusion: It was concluded that dental students, mainly female ones, have high prevalence of poor quality of sleep, which is associated with undergraduate student's worst academic performance.

Prevalence and associated factors of self-reported halitosis among institutionalized adolescents: Cross-sectional study.

OBJECTIVE: To assess the prevalence and associated factors of self-reported halitosis in institutionalized adolescents in a city in southern Brazil. METHODS: This cross-sectional study involved male institutionalized adolescents, aged 15-19 years old, at the Socio-Educational Assistance Center in the city of Passo Fundo, Brazil. Data collection was performed by a research team composed of two interviewers, two clinical examiners of oral health and two examiners of salivary flow. A structured questionnaire was applied, which included demographical, socioeconomical, general health behaviour, presence of health problems and oral health self-perception variables. Decayed, Missing, Filled Index was used for the clinical examination. The salivary flow collection was performed using the mechanically stimulated total saliva method, in which only the liquid component was measured. RESULTS: The prevalence of self-reported halitosis in this sample was 51.5% (n = 35). In the final multivariate analysis, halitosis was significantly associated with the non-white racial group (prevalence ratio [RP]:1.703; 95% confidence interval [95%CI]:1.101-2.634), use of crack (RP:1.857; 95%CI:1.270-2.714) and number of decayed teeth (PR: 1.123; 95%CI:1.008-1.252). The use of alcohol and access to dental care in the last 12 months were not significantly associated with self-reported halitosis. CONCLUSION: It was concluded that non-white and crack-user youngsters had a high occurrence of self-reported halitosis. Higher rates of dental caries are also associated with halitosis.

Use of dental implants among older adults of two southern Brazilian cities: A population-based cross-sectional study.

AIM: To assess the prevalence and associated factors with use of dental implants among older adults. METHODS: This cross-sectional study was performed with home dwelling older adults from the cities Cruz Alta and Veranópolis, Brazil. The main outcome was obtained by a clinical oral examination, considering those with at least one dental implant. Independent variables were collected by a structured questionnaire. Crude and adjusted analysis was performed by Poisson regression with robust variance estimation; results are presented in prevalence ratio (PR) and 95% confidence interval. RESULTS: It was included 569 participants. The overall prevalence of using at least one dental implant was 16.7%. Higher PR for the use of dental implants was observed in white individuals (PR:5.147; 95% CI:2.033-3.034), in those with at least medium income (PR:3.202; 95% CI:1.196-5.572) and in those with access to dental care in the last 12 months (RP:1.595; 95% CI:1.087-2.340). Older adults with a medium level of education (RP:0.484; 95% CI:0.240-0.978) and those that did not use dental floss (RP:0.627; 95% CI:0.240-0.978) demonstrated a significantly lower PR for use of dental implants. CONCLUSION: A substantial prevalence of use of dental implants was observed among older adults. In addition, white ones, those with a better financial situation and users of dental floss presented higher use of dental implants.
