Abstract Objective: To analyze if the oral health conditions in children and adolescents are associated with hemophilia (PROSPERO-42020168192). Material and Methods: The search strategy was performed in PubMed, Scopus, Lilacs/BBO, Web of Science, Cochrane, and Grey literature databases. Two independent researchers assessed the risk of bias in these studies by the Newcastle-Ottawa Scale. For the meta-analysis, the clinical conditions data were extracted as numerical variables according to their indexes, such as dental caries experience (dmft/DMFT), gingival condition (Modified Gingival Index - IGM), and oral hygiene (Plaque Index - PI). The quality of the evidence of the meta-analysis was evaluated by the GRADE tool (GRADEproGDT). Results: From a total of 431 studies, 27 were included, and 10 were included in the meta-analysis. The studies presented a moderate risk of bias, ranging from 2 to 7 points. The dental caries experience in primary (-0.62; CI95%: -1.68–0.43) and permanent dentitions (-0.05; CI95%: -0.69–0.59), gingival condition (-0.12; CI95%: -0.27–0.03), and oral hygiene (0.36; CI95%: -0.06–0.77) did not differ between the groups. Conclusion: Based on studies with very weak evidence, there were no differences in the oral health conditions of children and adolescents with and without hemophilia.

ABSTRACT Introduction: This systematic review was conducted to assess whether the use of a platelet aggregate injection with or without associated facial rejuvenation techniques favors facial rejuvenation in adult patients. Methods: Randomized clinical trials that compared the use of techniques for facial rejuvenation alone with the same techniques coupled with the injection of platelet aggregates were searched. The search was performed in indexed databases and in the gray literature. The Cochrane Collaboration bias risk tool was applied to assess the quality of the studies. Results: In total, 7137 articles were identified. Only four studies remained in the qualitative synthesis, and the others were considered as having undefined bias risk in the key domains. Conclusion: There are few studies in the literature that compare the use of platelet aggregates in facial rejuvenation and those that are available have a risk of “undefined” or “high” bias. There is a need for more well-designed clinical studies comparing the use of platelet aggregate injection with or without associated facial rejuvenation techniques.

RESUMO Introdução: Essa revisão sistemática foi conduzida para avaliar se a associação da aplicação da injeção de agregados plaquetários quando comparada a outras terapias faciais favorece no rejuvenescimento facial em pacientes adultos. Métodos: A pesquisa buscou ensaios clínicos randomizados que compararam uso de técnicas de rejuvenescimento facial isoladas com as mesmas técnicas aliadas à injeção de agregados plaquetários. A busca foi realizada em bases de dados indexadas e literatura cinzenta. A ferramenta de risco de viés da “Cochrane Collaboration” foi aplicada para a avaliação da qualidade dos estudos. Resultados: Foram identificados 7137 artigos. Apenas quatro estudos permaneceram na síntese qualitativa, e os demais foram considerados com risco indefinido de viés nos domínios chaves. Conclusão: Existem poucos estudos na literatura que comparam o uso de agregados plaquetários em rejuvenescimento facial e os que estão disponíveis têm risco de viés “indefinido” ou “alto”. Há necessidade de realizar mais estudos clínicos bem delineados que comparem o uso de injeção de agregados plaquetários associados ou não às técnicas de rejuvenescimento facial.

Abstract The objective of this systematic review was to compare the conical internal connection (IC) with the external hexagonal connection (EH) on the occurrence of marginal bone loss (ΔMBL). Different databases were used to carry out the selection of the elected studies. The studies were judged according to the risk of bias as “high”, “low” and “unclear” risk. For the meta-analysis we included only studies that could extract the data of ΔMBL, survival rate (SR) and probing depth (PD). No statistically significant differences were found for ΔMBL data at one, three- and five-year survival rates between implant connections (p <0.05), however statistically significant differences were found for PD between EH and IC implants (1-year follow-up) -0.53 [95%CI -0.82 to -0.24, p = 0.0004]. This present systematic review demonstrated that there are no significant differences between IC and EH implants for both ΔMBL and SR at 1, 3 e 5 years after functional loading, although better PD values were observed for implants pertaining to the IC connections. Considering the high heterogeneity, more well-delineated, randomized clinical trials should be conducted.

OBJETIVO: Avaliar a efetividade da supervisão de escovação em uma ou mais sessões na remoção de placa dental e desgaste de escovas. MATERIAL E MÉTODO: Crianças de 3 a 5 anos de idade receberam escovas dentais novas e participaram de um teatro de fantoches sobre saúde bucal. Foram selecionadas 49 e distribuídas aleatoriamente em três grupos (GI=20; GII=14 e GIII=14). A técnica de Fones foi demonstrada aos grupos GI e GII para avaliar:a supervisão profissional direta e o treinamento de escovação em cinco sessões (GI), a supervisão profissional direta e o treinamento em uma única sessão (GII) e a influência do teatro de fantoches (GIII-grupo controle). Os índices de placa dental (IPL) foram registrados no início do estudo (T0), após 24 dias (T1) e 46 dias (T2) e os índices de desgaste das escovas dentais (ID) no T1 e T2. Os testes de Kruskal-Wallis e Friedman (IPL); ANOVA de um critério e o teste t de Student (ID) (p<0,05) foram empregados na análise dos dados. RESULTADO: O GI diferiu de forma significativa dos outros grupos no T1 e T2 (p<0,01). O índice de desgaste das escovas aumentou (p<0,0001) dos 24 dias (0,52±0,35mm) para os 46 dias (0,90±0,48mm) e não houve associação significativa entre desgaste de escova e índice de placa, tanto em T1 (r=0,230-p= 0,116), quanto em T2 (r=0.226-p=0,121). CONCLUSÃO: A supervisão profissional em sessões múltiplas foi efetiva para reduzir os índices de placa, os quais não foram influenciados pelo desgaste das escovas, mostrando a necessidade de contínua motivação em higiene bucal.

OBJECTIVE: To evaluate the effectiveness of tooth brushing supervision in one or more sessions on dental plaque removal and toothbrush wear. MATERIAL AND METHOD: 3- to 5-year-old children received new toothbrushes and attended a puppet theater about oral health. Forty-nine children were randomly selected and divided into 3 groups (GI=20; GII=14; GIII=14). Fones' brushing method was demonstrated to the GI and GII groups to evaluate the following: the professional direct supervision and tooth brushing training in five sessions (GI), the professional direct supervision and a one-training session (GII) and the puppet theater influence only (GIII-control group). The dental plaque index (IPL) was recorded at baseline (T0), after 24 days (T1) and after 46 days (T2) and toothbrush wear (ID) was recorded on T1 and T2. The Kruskal-Wallis test and the Friedman test (IPL), as well as the one-way ANOVA and the paired Student's t-test (ID) (p<0.05) were employed to analyze the data. RESULT: GI showed a significant difference from the others groups in T1 and T2 (p<0.01).The index of toothbrush wear increased (p<0.0001) from 24 days (0.52±0.35mm) to 46 days (0.90±0.48mm), but there was no significant association between toothbrush wear and plaque index for T1 (r=0.230-p= 0.116) as well as for T2 (r=0.226-p=0.121). CONCLUSION: The multiple sessions of professional supervision were effective to reduce the dental plaque index, which was not influenced by toothbrush wear, showing continuous oral hygiene motivation needs.
