RESUMO
OBJECTIVE: To systematically evaluate randomized controlled trials (RCTs), with at least 6 months of follow-up, on whether professional mechanical plaque removal (PMPR) including supragingival scaling should be performed prior and separately from subgingival scaling and root planning (SRP) in nonsurgical periodontal therapy (NSPT), in terms of clinical and patient-reported outcomes (PROs) (CRD42020219759). METHODS: The MEDLINE, EMBASE, CENTRAL, LILACS and Web of Science electronic databases, as well as grey literature sources, were searched by two independent reviewers up to May 2023. The Cochrane Collaboration's Risk of Bias tool (RoB 2.0) was used for quality appraisal and GRADE for assessing the certainty of evidence. Random-effects pairwise meta-analyses compared the changes in probing pocket depth (PPD), clinical attachment loss (CAL), and bleeding on probing (BoP) of a stepwise NSPT approach (PMPR prior and separately from SRP) and conventional one-step NSPT through mean differences (MDs) and associated confidence intervals (95% CI). RESULTS: Two RCTs were included, including data of 77 participants with severe periodontitis. One RCT presents high risk of bias and the other has some concerns. No significant differences were found between the stepwise approach and performing both steps simultaneously for any clinical outcomes, with overall very low certainty on evidence. No adverse effects were detected and there was no data on PROs. CONCLUSIONS: There is very-low certainty evidence of no significant difference on PPD and BoP reductions and CAL gain between supragingival scaling performed prior and separately from SRP and conventional one-step NSPT.

This meta-research aimed to provide an overview of the methodological quality and risk of bias of network meta-analyses (NMA) in dentistry. Searches for NMA of randomized clinical trials with clinical outcomes in dentistry were performed in databases up to January 2022. Two reviewers independently screened titles/abstracts, selected full texts, and extracted the data. The adherence to PRISMA-NMA reporting guideline, the AMSTAR-2 methodological quality tool, and the ROBIS risk of bias tool were assessed in the studies. Correlation between the PRISMA-NMA adherence and the AMSTAR-2 and ROBIS results was also investigated. Sixty-two NMA studies were included and presented varied methodological quality. According to AMSTAR-2, half of the NMA presented moderate quality (n = 32; 51.6%). The adherence to PRISMA-NMA also varied. Only 36 studies (58.1%) prospectively registered the protocol. Other issues lacking of reporting were data related were data related to the NMA geometry and the assessment of results consistency, and the evaluation of risk of bias across the studies. ROBIS assessment showed a high risk of bias mainly for domains 1 (study eligibility criteria) and 2 (identification and selection of studies). Correlation coefficients between the PRISMA-NMA adherence and the AMSTAR-2 and ROBIS results showed moderate correlation (rho < 0.6). Overall, NMA studies in dentistry were of moderate quality and at high risk of bias in several domains, especially study selection. Future reviews should be better planned and conducted and have higher compliance with reporting and quality assessment tools.

RESUMO
Periodontitis and arterial hypertension are two of the pathologies with the highest global prevalence; evidence reported so far has been favorable to an association between them. This cross-sectional study aimed to evaluate and compare the microbiological counts of hypertensive and normotensive patients with periodontitis. Sociodemographic, behavioral, systemic health data and periodontal clinical parameters were assessed. Counts of A. actinomycetemcomitans, P. intermedia, P. gingivalis and F. nucleatum were performed by real-time polymerase chain reaction using subgingival biofilm samples. Thirty-eight patients were included in this preliminary analysis, divided into two groups: Normotensive Group (NG) (n = 14) and Hypertensive Group (HG) (n = 24). Patients diagnosed with periodontitis composed both groups. Data analysis was performed with significance level of 5%. There was no significant difference between groups for clinical periodontitis diagnosis. In addition, hypertensive individuals had higher P. intermedia, P. gingivalis, and F. nucleatum counts when compared to normotensive individuals. The parameters probing pocket depth, bleeding on probing, and A. actinomycetemcomitans count did not presented statistical differences between groups. With these preliminary results, it can be concluded that the presence of arterial hypertension may be associated with a greater quantity of periodontopathogenic bacterial of some species in individuals with periodontitis.

Resumo A periodontite e a hipertensão arterial são duas das patologias com maior prevalência global, as evidências relatadas até o momento têm sido favoráveis a uma associação entre elas. Este estudo transversal teve como objetivo avaliar e comparar contagem microbiológicas de pacientes hipertensos e normotensos com periodontite. Dados sociodemográficos, comportamentais, de saúde sistêmica e parâmetros clínicos periodontais foram avaliados. Contagens de A. actinomycetemcomitans, P. intermedia, P. gingivalis e F. nucleatum foram realizadas por reação em cadeia da polimerase em tempo real utilizando amostras de biofilme subgengival. Trinta e oito pacientes foram incluídos nesta análise preliminar, divididos em dois grupos: Grupo Normotenso (GN) (n = 14) e Grupo Hipertenso (GH) (n = 24). Pacientes diagnosticados com periodontite compuseram os dois grupos. A análise dos dados foi realizada com nível de significância de 5%. Não houve diferença significativa entre os grupos para o diagnóstico clínico de periodontite. Além disso, os hipertensos apresentaram maior contagem de P. intermedia, P. gingivalis e F. nucleatum quando comparados aos normotensos. Os parâmetros profundidade de sondagem, sangramento à sondagem e contagem de A. actinomycetemcomitans não apresentaram diferenças estatísticas entre os grupos. Com esses resultados preliminares, pode-se concluir que a presença de hipertensão arterial pode estar associada a uma maior quantidade de bactérias periodontopatogênicas de algumas espécies em indivíduos com periodontite.
RESUMO
Objective: To assess the caries progression and the need for reintervention on occlusal ICDAS 4 lesions after different treatments. Material and Methods: The sample consisted of records of children treated in a public setting who had at least an occlusal ICDAS 4 lesion in primary and/or permanent molars. The radiographic images of ICDAS 4 lesions at the first and last appointments were classified as absence of radiolucency, radiolucent image at the enameldentin junction, at the outer half or inner of the dentin. The need for retreatment after different treatments (non-invasive - topical fluoride applications, oral hygiene instructions and dietary guidance, micro-invasive - resin-based sealant, or invasive - restoration) was assessed by reviewing clinical and radiographic records. The need for retreatment was defined as any complication requiring mending (e.g., caries progression, total loss of sealant, or restoration failure). The Poisson regression model was used to investigate the association between individual and tooth-related variables and the outcome. Results: Among the 111 lesions in 81 patients, most (73.0%) lesions were in primary molars. Most lesions (52.3%) did not exhibit radiolucency, whereas 29.7% had radiolucency at the outer half of the dentin. The mean follow-up was 18.8 ± 6.5 months. After follow-up, 82.9% of the lesions did not require retreatment. The prevalence of ICDAS 4 lesions that did not need retreatment was higher among lesions with radiolucency at dentin (p=0.01). Conclusion: Most occlusal ICDAS 4 lesions did not require reintervention, especially those exhibiting radiolucency in the outer half of the dentin (AU)
Objetivo: Avaliar a progressão de cárie e a necessidade de reintervenção em lesões oclusais ICDAS 4 após diferentes tratamentos. Material e Métodos: A amostra consistiu de prontuários de crianças atendidas em ambiente público que apresentavam pelo menos uma lesão oclusal ICDAS 4 em molares decíduos e/ou permanentes. As imagens radiográficas de lesões ICDAS 4 na primeira e última consultas foram classificadas como ausência de radiolucidez, imagem radiolúcida na junção esmalte-dentina, em metade externa ou interna da dentina. A necessidade de retratamento após diferentes tratamentos (não invasivo aplicações tópicas de flúor, orientações de higiene e dieta, micro-invasivo selante resinoso ou invasivo restauração) foi avaliada por meio da revisão dos registros clínicos e radiográficos. A necessidade de retratamento foi definida como qualquer complicação que requer intervenção (por exemplo, progressão da lesão, perda total do selante ou falha na restauração). O modelo de regressão de Poisson foi utilizado para investigar a associação entre as variáveis individuais e dentárias e o desfecho. Resultados: Entre as 111 lesões em 81 pacientes, a maioria (73,0%) das lesões eram em molares decíduos. A maioria das lesões (52,3%) não exibiu radiolucidez, enquanto que 29,7% apresentaram radiolucidez em metade externa de dentina. O tempo de acompanhamento médio foi de 18,8 ± 6,5 meses. Após o acompanhamento, 82,9% das lesões não necessitaram de retratamento. A prevalência de lesões ICDAS 4 que não necessitaram de retratamento foi maior entre as lesões com radiolucidez em dentina (p=0,01). Conclusão: A maioria das lesões oclusais ICDAS 4 não requerem reintervenção, especialmente aquelas que exibem radiolucidez em metade externa da dentina.(AU)

Purpose: To evaluate the effect of caries management on the periodontal status of preschool and school-age children.
Methods: Twenty-six four- to eight-year-old children with at least one primary molar with a deep carious lesion were selected to undergo a periodontal evaluation before and six months after dental treatment. Two examiners conducted the periodontal exams using the visible plaque index (VPI) and gingival bleeding index (GBI). Longitudinal changes were compared using paired t-test and Fisher's test. Poisson regression models were used to investigate the variables influencing GBI (α =five percent).
Results: There were no significant differences in the mean percentage of VPI-positive sites (55.8±26.9 percent to 54.5±29.8 percent; P =0.829) and GBI-positive sites (37.2±22.2 percent to 32.1±22.8 percent; P =0.222) before and after treatment. In contrast, the mean number of GBI sites decreased from 8.5±5.03 to 6.3±4.39 (P =0.026), while the percentage of patients presenting GBI of no more than 10 percent increased from 11.5 percent to 26.9 percent over time (P =0.013). Similar analyses for VPI did not show a statistical significance. Boys (P =0.037) and six- to eight-year-old children ( P =0.029) had lower reductions on GBI.
Conclusion: Caries management has a positive impact on the periodontal condition of children, especially on gingival bleeding.

AIMS: SARS-CoV-2 RNA has been recovered from different sites in the human body, including the mouth. The present study aimed to investigate the presence of SARS-CoV-2 RNA in the dental biofilm of symptomatic patients who tested positive in nasopharyngeal and oropharyngeal (NASO/ORO) samples. MATERIALS & METHODS: An observational clinical study of individuals with flu-like symptoms was conducted between July and September 2020. Dental biofilm (BIO) samples were collected and analysed using real-time quantitative polymerase chain reaction (RT-qPCR) to determine the virus's presence. RESULTS: Seventy participants (40 ± 9.8 years of age, 71.4% female) tested positive for SARS-CoV-2 RNA in NASO/ORO samples and were included in the study. Among them, 13 tested positive in BIO samples (18.6%; 95% CI: [9.5, 27.7]). The median and interquartile range of cycle quantification (Cq) for NASO/ORO and BIO samples were 15.9 [6.9] and 35.9 [4.0] (p = .001), respectively. BIO-positive participants showed a higher virus load in NASO/ORO samples (p = .012) than those testing negative (Cq = 20.4 [6.1]). CONCLUSIONS: Dental biofilms from symptomatic COVID-19 patients harbour SARS-CoV-2 RNA and might be a potential reservoir with an essential role in COVID-19 transmission.

AIM: Assessment of Oral Health Impact Profile (OHIP-14) during a randomized controlled trial of supportive periodontal therapy (SPT) consisting of oral prophylaxis with oral hygiene instructions only (test) or in conjunction with subgingival instrumentation (control). METHODS: OHIP-14 was assessed at baseline, 6, 12, 18 and 24 months. Data from 62 participants (50.97 ± 9.26 years, 24 smokers) were analysed by GEE and Logistic regression. OHIP-14 means, effect size, floor and ceiling effect and minimal important difference were calculated. Sum of OHIP-14 (severity), numbers of responses (extent) "fairly often" (FO) or "very often" (VO) and percentage of people (prevalence) reporting FO or VO were computed. RESULTS: At baseline, low scores of OHIP-14 were observed for test (7.67 ± 9.27) and control (6.51 ± 7.47) with a decreasing trend during SPT, without differences between or intra-groups over time. At 6 months, a difference was observed in the OHIP-14 prevalence (p = .03), without differences in severity and extent. Smoking status and plaque >15% (moderate oral hygiene) at 24 months were associated with higher OHIP-14 prevalence scores at that point of time (p = .038 and p = .034, respectively). CONCLUSION: Patients submitted to two different modalities of SPT maintained low OHIP-14 scores over 2 years of care.

BACKGROUND: Acid sphingomyelinase deficiency (ASMD) is a rare group of autosomal recessive disorders. This report provides the first detailed description of the periodontal condition and treatment response in a patient with chronic visceral ASMD. CASE DESCRIPTION: A 49-year-old white woman with ASMD showed elevated visible plaque index (VPI), gingival bleeding index (GBI), and bleeding on probing (BOP) at 100% of sites. Periodontal pocket depths (PPD) were mostly shallow to moderate (at 96% of sites), whereas the loss of clinical attachment (CAL) was moderate to severe (54% and 46% of sites, respectively, at 4-6 mm and ≥7 mm categories). Periapical radiographs revealed the presence of furcation involvement and intra-bony defects. The periodontal diagnosis was periodontitis stage IV, generalized, grade C. Ninety days after the end of the supra and subgingival control (e.g., cause-related therapy), marked reduction was observed for all periodontal indicators: VPI (-83%), GBI (-79%), BOP (-85%), elimination of sites PPD ≥7 mm, 27% increase in sites PPD 1-3 mm (from 64% to 91%), and gain of clinical attachment (gain of 11% CAL 1-3 mm and 25% CAL 4-6 mm; and a reduction of 36% CAL ≥7 mm). PRACTICAL IMPLICATIONS: Despite the severity of the initial periodontal condition, the patient with chronic visceral ASMD responded well to the non-surgical periodontal treatment.
