Background: Prevalence data about tooth erosion has attracted increasing attention in the dental community; however, no study has addressed the impact of this condition on child oral health-related quality of life (COHRQoL). This study assessed the impact of tooth erosion on COHRQoL. Methods: This study followed a cross-sectional design, with a multistage random sample of 944 11- to 14-year-old children representative of Santa Maria, a southern city in Brazil. They were examined for recording the prevalence and severity of tooth erosion by 2 examiners. Children completed the Brazilian version of Child Perceptions Questionnaire (CPQ_11–14) and data about socioeconomic variables of the target population were collected by means of a structured questionnaire. The Poisson regression model using robust variance was performed to assess the association between the predictor variables and the outcomes. Results: Prevalence of tooth erosion (7.2%) and severity were low. Poisson regression models showed a distinct gradient in mean CPQ_11–14 scores by socioeconomic indicators. Children with tooth erosion with low levels of severity did not report higher means in the total scores or domains of CPQ_11–14. Conclusion: The presence of tooth erosion of low severity did not have a significant negative impact on the children’s perception of oral health or on their daily performance.

All groups showed some level of toxicity. Amongst the main solutions, chlorhexidine presented less cytotoxic potential. EDTA was the least cytotoxic of the auxiliary irrigant solutions, and the association of these two solutions showed the lowest toxicity potential amongst all groups.

A interligação morfofuncional da cavidade oral com a face determina uma relação nos processos de crescimento e de desenvolvimento dessas áreas, responsabilizando as funções faciais (respiração, sucção, deglutição, mastigação e fala) pelos estímulos paratípicos adequados para o crescimento determinado geneticamente. Por isso, as alterações funcionais poderão gerar um comprometimento do desenvolvimento facial, assim como das estruturas as quais a face está relacionada. A amamentação exige um trabalho muscular intenso do recém-nascido, promovendo a sucção, a deglutição e a respiração (funções vitais e inatas) estimulando o crescimento e desenvolvimento da face e seus anexos. Neste trabalho, objetivou-se contextualizar a influência do aleitamento (natural e artificial) no desenvolvimento do sistema estomatognático, fornecendo subsídios para que o cirurgião-dentista clínico geral tenha condições de diagnosticar alterações nos padrões fisiológicos neuromusculares faciais, bem como orientar e encaminhar o paciente para um tratamento com atenção multidisciplinar, promovendo a saúde em uma faixa etária bem precoce.

The pastes varied in their ability to induce cytotoxicity, genotoxicity and oxidative stress. In general, Guedes-Pinto, Maxitrol and neomycin sulphate + bacitracin pastes exhibited better biocompatibility in vitro.

Guedes-Pinto paste is the filling material most employed in Brazil for endodontic treatment of deciduous teeth; however, the Rifocort ® ointment has been removed. Thus, the aim of this study was to investigate the antimicrobial potential of filling pastes, by proposing three new pharmacological associations to replace Rifocort ® ointment with drugs of already established antimicrobial power: Nebacetin ® ointment, 2% Chlorhexidine Gluconate gel, and Maxitrol ® ointment. A paste composed of Iodoform, Rifocort ® ointment and Camphorated Paramonochlorophenol (CPC) was employed as the gold standard (G1). The other associations were: Iodoform, Nebacetin ® ointment and CPC (G2); Iodoform, 2% Chlorhexidine Digluconate gel and CPC (G3); Iodoform, Maxitrol ® ointment and CPC (G4). The associations were tested for Staphylococcus aureus (S. aureus), Streptococcus mutans (S. mutans), Streptococcus oralis (S. oralis), Enterococcus faecalis (E. faecalis), Escherichia coli (E. coli), and Bacillus subtilis (B. subtilis),using the methods of dilution on solid medium -orifice agar -and broth dilution. The results were tested using statistical analysis ANOVA and Kruskal-Wallis. They showed that all the pastes had a bacteriostatic effect on all the microorganisms, without any statistically significant difference, compared with G1. S. aureus was statistically significant (multiple comparison test of Tukey), insofar as G2 and G3 presented the worst and the best performance, respectively. All associations were bactericidal for E. coli, S. aureus, S. mutans and S. oralis. Only G3 and G4 were bactericidal for E. faecalis, whereas no product was bactericidal for B. subtilis. Thus, the tested pastes have antimicrobial potential and have proved acceptable for endodontic treatment of primary teeth.
