Aplicação da técnica de condicionamento total ou de primers autocondicionantes em dentes decíduos após abrasão a ar

Since the use of air abrasion has grown in pediatric dentistry, the aim of this study was to evaluate, by means of shear bond strength testing, the need to use the total etching technique or self-etching primers on dentin of primary teeth after air abrasion. Twenty-five exfoliated primary molars had their occlusal dentin exposed by trimming and polishing. Specimens were treated by: Air abrasion + Scotchbond MultiPurpose adhesive (G1); 37% phosphoric acid + Scotchbond MP adhesive (G2); Clearfil SE (G3); Air abrasion ( 37% phosphoric acid + Scotchbond MP adhesive (G4); Air abrasion + Clearfil SE (G5). On the treated surface, a cylinder of 2 mm by 6 mm was made using a composite resin (Z100). Duncan's test showed that: (G2 = G3 = G5) > (G1 = G4). The use of a selfetching primer on air abraded dentin is recommended to obtain higher bond strengths.

O Papel do cirurgião-dentista nas desordens alimentares: uma revisão de literatura

As desordens alimentares são um grupo de desordens psicopatológicas, nas quais o paciente relaciona os alimentos ingeridos com seu próprio corpo e, podem ameaçar a vida, como a anorexia e bulimia nervosa. Durante a progressão das desordens alimentares, pode ocorrer uma série de manifestações orais, as quais exercem um papel fundamental no diagnóstico, caracterização e prognóstico dessas desordens. O cirurgião dentista é, na maioria das vezes, o primeiro profissional da saúde a observar os sintomas clínicos de uma desordem alimentar. O objetivo deste trabalho foi realizar uma revisão de literatura sobre a etiologia, características, manifestações orais, e tratamento das lesões orais decorrentes das desordens alimentares. A pesquisa foi realizada nas bases de dados PubMed, SciELO, Bireme, durante o período de 1987 a 2013. Verifica-se assim que os primeiros sinais desenvolvidos em pacientes com desordens alimentares aparecem na cavidade oral, cabendo ao cirurgião dentista identificar esses sinais e relacioná-los às desordens.

Retromolar canal associated with age, side, sex, bifid mandibular canal, and accessory mental foramen in panoramic radiographs of Brazilians

Background. The retromolar canal (RMC) is an anatomical variation that can cause complications in dental procedures. Method. The RMC was evaluated according to age, sex, and presence of accessory mandibular canal and accessory mental foramen, on both sides in 500 panoramic radiographs, belonging to individuals at the age of 7 to 20 years. The associations of interest were studied through Fisher's Exact Test and Pearson's Chi-Square Test, and the correlation was studied through Pearson's Correlation Coefficient (r). The significance level used was 5%. Results. The RMC was observed in 44 radiographs (8.8%), and out of those 24 were females. There was no statistically significant association between the RMC and age (p > 0.05; Fisher's Exact Test), sex (p = 0.787; Pearson's Chi-Square Test), amount of mandibular canals and mental foramina, on both sides (p > 0.05; Pearson's Chi-Square Test). There was a significant association between RMC and side, the higher frequency of the canal being on the right side (p < 0.05; Fisher's Exact Test). Conclusions. Despite the low occurrence of the RMC, its identification and the verification of its dimensions and path are relevant, mainly in cases when anesthetic and surgical procedures can present failures or difficulties.
