Background: Shade matching is a significant treatment step and a challenge for the clinical team with potentially high costs for color correction. Currently, in the United States, the majority of private dental practitioners use visual color matching, but a recent study has reported a high rate of mistakes of subjective color determination among graduate dentists. Objective: The aim of this retrospective study is to analyze whether a change in the oral background due to dental occlusion can influence tooth color determination.

Background: Internal hernia is a rare but a potentially fatal complication of laparoscopic Roux-En-Y gastric bypass (LRYGB). The aims of this study are to determine the impact of mesenteric defects closure on the incidence of internal hernia after LRYGB and to determine the symptoms, characteristics, and management of internal hernias after LRYGB. Methods: A retrospective study for a total of 2093 LRYGB was carried out from 1998 to December 2013. Four hundred twenty-one patients were operated without closure of the mesenteric defects (group A).
