ABSTRACT
A configuração de canais em formato de C em molares é uma variação anatômica que dificulta o diagnóstico e tratamento. O objetivo deste estudo foi relatar um caso de configuração de canal em C no segundo molar inferior. O exame radiográfico do paciente revelou uma cárie extensa na porção mesial do segundo molar inferior, sem a presença de lesão periapical e foi clinicamente observada a configuração em C do canal radicular, que se estendeu desde o canal mesiovestibular até o canal distal. A terapia endodôntica foi realizada e após a obturação dos canais, o dente foi restaurado. Concluiu-se que após 12 meses de acompanhamento clínico e radiográfico, verificou-se que a terapia teve um resultado satisfatório.
C-shape configuration in molars is an anatomical variation that difficults diagnosis and treatment. The aim of this study was to report a case of C-shape endodontic configuration in a mandibular second molar. The radiographic examination of one patient revealed the extent of caries in the mesial aspect of mandibular second molar, without the presence of periapical lesion and was clinically noted the C-shape configuration of the root canal, extending from the mesiobuccal to the distal canal. Endodontic therapy was performed and after the root canal filling, the tooth was restored. We conclude that after 12 months of clinical and radiographic follow-up, satisfactory outcome of the treatment was observed

AIM: evaluate the color changes in acrylic resins immersed in two pigmented beverages in different time periods, proportional to the frequency and volume of consume by the population with and without the use of artificial saliva. MATERIAL AND METHODS: Thirty thermo-polymerizable resin disks were confectioned with 3.0 +- 0.1 mm thickness, initially immersed in distilled water for 24 hours and randomly divided into 2 groups (n=15): GC with artificial saliva and GS without artificial saliva. They were, then, subdivided into 3 subgroups (n=5): G1 distilled water (control); G2 red wine; G3 black tea. These groups were daily immersed inside beverages for 15 days, with daily immersion frequency equal to the beverage ingestion and the period of each immersion equal to 1 minute/10 ml of beverage per capita. Between each immersion the disks were stored inside distilled water. The color of resins was measured according to the CIE-Lab scale before and after the immersion periods, and the color variation was calculated (ΔE). The values ΔL*, Δa* e Δb* were also evaluated. RESULTS: Analysis of variance was performed, and have shown significant difference (p<0.05) among G1 and the other solutions, without significant difference between G2 and G3 for ΔE, ΔL, Δa and the module Δb. There was no difference between GC and GS. CONCLUSION: It was concluded that the use of artificial saliva did not change pigmentation degree and that wine presents similar changes to the tea, considering the parameters used.
