RESUMO
Genetic polymorphisms could explain the inter-individual differences in the oral health-related quality of life (OHRQoL) of children with anterior open bite (AOB). OBJECTIVE: To assess the impact of AOB on OHRQoL in children and to evaluate whether MTR (rs1805087), MTRR (rs1801394), TGFß1 (rs1800469) and TNF-α (rs1799964, rs1799724 and rs1800629) genes are potential biomarkers for OHRQoL in children with AOB. STUDY DESIGN: A cross-sectional study was performed with 173 children aged between 2-6 years. The Brazilian version of Early Childhood Oral Health Impact Scale (ECOHIS) was applied. Genetic polymorphisms were analyzed using real-time PCR. Mann-Whitney U-test and Chi-square were used. RESULTS: The overall mean ECOHIS scores were 5.49 (SD= 5.72) and 3.45 (SD = 4.49) (p < 0.01) in the AOB and control groups, respectively. Children with the CC genotype of TNF-α (rs1799724) had a significantly higher psychological QoL level. The MTRR AA genotype group showed a lower QoL level in the child subscale (p = 0.006), function (p = 0.017), and psychological (p = 0.006) domains. There was no significant difference between OHRQoL and the genetic polymorphisms in MTR and TGFß1. CONCLUSIONS: Genetic polymorphisms in TNF-α and MTRR are associated with the impact on the OHRQoL in children with AOB.

How patients perceive impact of diseases is an essential component when characterising different disease impacts, and effects of dental treatments should be perceived by the patients. This study aimed to assess the impact of conservative treatment of deep caries lesions using the selective caries removal (SCR) associated to a low laser therapy (antimicrobial photodynamic therapy-aPDT) on oral health-related quality of life (OHRQoL). STUDY DESIGN: A non-randomized clinical before-and-after study was conducted on children aged 4 to 8 years. The data was obtained applying the Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS) to the caretakers in an interview before and after treatment. The paired T-student test considering p<0.05 and the treatment responsiveness detecting the effect size by means of standardized response mean (SRM) was evaluated. RESULTS: The mean impact on OHRQoL on the total scale was 5.46 ± 4.54 for before and 2.42 ± 3.54 for after treatment (p<0.01). The ECOHIS demonstrated satisfatory longitudinal responsiveness except for psychological, self-image/social interaction and Family function domain (SRM<0.5). CONCLUSION: This study demonstrated that the association of a low laser therapy (aPDT) with SCR did not influence negatively on OHRQoL. In the practice of pediatric dentistry, this conservative dental treatment improved the OHRQoL after 3 months of follow up.

BACKGROUND: Dental caries is a dysbiotic polymicrobial disease that can cause damage to an individual's successful, elite sporting performance. AIMS: This study aimed to realize a meta-analysis to calculate a worldwide, pooled estimated prevalence of dental caries in athletes. METHODS AND MATERIALS: This systematic review and meta-analysis was registered in PROSPERO (n° CRD42017068127). A systematic search was conducted in the electronic databases Pubmed, Scopus, Web of Science, Virtual Health Library (Lilacs) and Grey literature from inception up to April 2017. The MeSH terms "Sports," Athletes," and "Dental Caries" were used. The inclusion criteria used in this review were observational cross-sectional studies, longitudinal retrospective, and prospective studies that presented the prevalence of dental caries in athletes without intellectual disabilities. From selected articles, the risk of bias tools were assessed. After considering the qualitative heterogeneity among studies, a meta-analysis was conducted. RESULTS: A total of 1,376 abstracts were initially retrieved, with only five meeting the inclusion criteria. Of these, one was considered to have a low risk of bias and four were considered to have a moderate risk of bias. The overall estimated prevalence of dental caries in athletes was 46.25% (95%CI 28.73-64.27). CONCLUSION: The estimated prevalence of dental caries in athletes, and particularly in athletes from developing countries is considered to be high. The pooled prevalence estimates have important implications in regard to preventive measures and research planning around the world.

This review summarizes the reported molecular mechanisms underlying the antileukemic property of Sesquiterpene Lactones (SLs). This systematic review was registered in the PROSPERO database and conducted following the PRISMA Statements. The MeSH terms, Sesquiterpenes, Lactones and Leukemia were used in four databases (Pubmed, Web of Science, Scopus and Bireme). There were 281 studies selected, but after exclusions, due to replication (n = 172) or not following PECOS criteria (n = 24), 148 studies remained. Of the 148 articles, only 22 were submitted to quality assessment and were scored in high level if more than two techniques, to elucidate antileukemic properties, were described, and then data were extracted. The studies mostly used human leukemia cell lines including primary and established cells, with or without chemotherapy resistance. The SLs used were obtained principally from plants. The antileukemic properties of SLs were extracted from 22 high level studies. They included cell death induction, mainly by apoptosis, as well as cell differentiation, cell cycle disruption, leukemia cancer stem cell growth inhibition and NF-κB pathway inhibition; the latter is a promising therapeutic target for lymphoid malignancies. We concluded that, in spite of the necessity of better toxicological profile characterization of SLs, the antileukemic properties of these compounds support the proposal that the SLs are promising candidates for the treatment of leukemia.
