O objetivo deste caso clínico foi relatar a importância da ortodontia interceptativa associada ao acompanhamento otorrinolaringológico e fonoaudiológico em uma criança com diagnóstico de atresia dos maxilares. Paciente leucoderma, 5 anos de idade, sexo feminino, procurou atendimento odontológico com queixa de apinhamento dentário. A avaliação clínica e a documentação ortodôntica evidenciaram relação molar Classe I, relação canina Classe III, perfil convexo, retrusão do incisivo inferior, profundidade facial com retrusão mandibular, profundidade da maxila com retrusão maxilar e comprimento craniano anterior pequeno. A criança foi avaliada por um médico otorrinolaringologista que diagnosticou hipertrofia de adenoides, com saída de ar limítrofe, sem indicação de adenoidectomia. O tratamento proposto foi a disjunção da maxila com aparelho palatino de Haas associada à expansão lenta da mandíbula com um aparelho expansor removível. No mesmo período, a criança iniciou tratamento fonoaudiológico para restabelecimento das funções orofaciais, pois apresentava baixa tonicidade das bochechas e do lábio inferior com eversão discreta, lábio superior encurtado e hipertrofia do mento. Quanto à evolução clínica da criança, notou-se aumento do tônus orofacial de lábios e bochechas e diminuição do tônus do mentual, melhor padrão mastigatório alternado com fechamento labial mais frequente e melhor produção dos bilabiais durante a fala espontânea. Pôde-se concluir que a expansão rápida da maxila associada à expansão lenta da mandíbula foram efetivas no tratamento da criança, proporcionando bons resultados na deficiência da dimensão transversal. Além disso, a abordagem multiprofissional com Odontopediatria, Otorrinolaringologia e Fonoaudiologia contribuiu para o sucesso do processo terapêutico da criança.
The aim was to report the use low-level laser therapy (LLLT) in the management of hypersensitivity in an adolescent with molar incisor hypomineralization (MIH) and the impact of LLLT on his oral health-related quality of life (OHRQoL). Clinical examination revealed severe MIH with hypersensitivity, in all first permanent molars and incisors. The treatment proposed was desensitization with fluoride and esthetic rehabilitation of the affected teeth. Then, LLLT was applied perpendicularly in a continuous mode (wavelength of 808 nm, power of 100 mW, dose of 1 J, and fluence of 35 J/cm2). The visual analogue scale was applied each session of LLLT. The child perceptions questionnaire (CPQ11–14) was administered at the beginning and the end of the treatment. It was concluded that LLLT can be indicated in the management of hypersensitivity in an adolescent with severe MIH to control pain and to improve his OHRQoL.
Objective: To investigate the association between oral health problems and being ashamed of smiling or speaking among Brazilian adolescents. Material and Methods: This was a population-based cross-sectional study carried out with secondary data from 7,328 12-year-old Brazilian adolescents from the latest Brazilian national oral health survey (SB Brasil 2010). The question "In the previous 6 months, have you been ashamed of smiling or speaking due to your teeth?" was the outcome variable. Calibrated examiners performed clinical examinations on adolescents for the diagnosis of dental caries (DMF-T), dental trauma, dental fluorosis and occlusal alterations. Data were analyzed descriptively and by Poisson unadjusted and adjusted Poisson regression analysis (p<0.05). The final model was controlled by family income. Results:The prevalence of being ashamed of smiling or speaking was 13.6%. The following variables were associated with the outcome: female sex (PR=1.33; 95% CI: 1.17-1.53), cavitated dental caries on upper incisors (PR=1.81; 95% CI: 1.51-2.15), dental trauma (PR=1.36; 95% CI:1.16-1.60), increased maxillary overjet (PR=1.36; 95% CI:1.18-1.57), dental crowding (PR=1.60; 95% CI:1.40-1.83), midline diastema (PR=1.30; 95% CI:1.11-1.44), tooth loss (PR=1.45; 95% CI:1.16-1.80), mild/questionable dental fluorosis (PR=1.23; 95% CI:1.06-1.44) and moderate/severe dental fluorosis (PR=1.67; 95% CI:1.15-2.44). Conclusion: Oral health problems that impact dental aesthetics were predisposing factors for being ashamed of smiling or speaking in Brazilian adolescents.
O objetivo deste estudo foi avaliar o efeito do flúor e do xilitol na atividade antimicrobiana de dentifrícios infantis contra Streptococcus mutans por difusão em ágar. Seis dentifrícios foram testados de acordo com a presença/concentração de flúor e xilitol: 1-Condor Bambinos; 2-Bitufo Cocoricó; 3-Colgate Smiles; 4-Bitufo Penélope; 5-Tandy e 6-Aquafresh Kids. Após a solidificação do meio ágar em placas, 200µL do inóculo (S. mutans UA 159) foram dispensados sobre o meio e cinco poços foram confeccionados em cada placa para preenchimento com os dentifrícios, totalizando dez poços para cada dentifrício. As placas foram incubadas a 37ºC por 48h. Os valores de halos de inibição foram analisados por ANOVA one-way e Tukey (α=0,05%). Houve diferença significante entre os dentifrícios fluoretados, de modo que o dentifrício Aquafresh apresentou o maior halo de inibição contra S. mutans. A concentração de flúor influenciou a atividade antimicrobiana dos dentifrícios infantis, entretanto, o xilitol não exerceu influência. Descritores: Flúor; Xilitol; Streptococcus mutans; Dentifrícios.The aim of this study was to evaluate the antimicrobial effect toothpastes for infants containing fluoride and xylitol presented against Streptococcus mutans, through an agar diffusion test. Six toothpastes were categorized according to the presence/concentration of fluoride and xylitol: 1-Condor Bambinos; 2-Bitufo Cocoricó; 3-Colgate Smiles; 4-Bitufo Penelope; 5-Tandy and 6-Aquafresh Kids. After the solidification of an agar medium in the dishes, 200 µL of the inoculum (S. mutans UA 159) were dispensed on the medium and five holes were made in it for the application of the dentifrices, totalizing 10 wells for each one. The plates were incubated at 37ºC for 48h. The inhibition zones were analyzed through the ANOVA one-way and Tukey (α=0.05) tests. There was a significant difference between fluoridated dentifrices, as the Aquafresh showed the biggest inhibition halos against S. mutans. The concentration of fluoride influenced the antimicrobial activity of child toothpastes; xylitol, however, had no influence. Descriptors: Fluorine; Xylitol; Streptococcus mutans; Dentifrices.El objetivo de este estudio fue evaluar el efecto del flúor y xilitol sobre la actividad antimicrobiana en dentífricos para niños contra Streptococcus mutans por difusión en agar.

Existió diferencia significativa entre los dentífricos fluorados, por lo que el dentífrico Aqua...
