Association between gastric reflux, obesity and erosive tooth wear among psychiatric patients.

The prevalence of erosive tooth wear and obesity are high in psychiatric patients and soft drink consumption is a common risk factor associated with both diseases. This study aimed to assess the association between soft drink consumption, gastric reflux, erosive tooth wear, and obesity among resident patients at the Psychiatric Hospital, Taif, Saudi Arabia.This descriptive, cross-sectional study included 223 adult psychiatric inpatients (126 male, 97 female) with a mean age of 42.

Effect of Multilayering Incremental Technique on the Microleakage of High-viscosity Bulk-fill Composite Restorations in Endodontically Treated Teeth.

Aim: The aim of this study is to evaluate the effect of multilayering incremental technique on the microleakage of high-viscosity bulk-fill composite restorations in endodontically treated teeth.

Materials And Methods: A total of 60 human mandibular premolar teeth were divided into four groups after standardized access preparation with a protaper technique followed by single-cone obturation to receive the following restorations for the access preparations. Group I ( = 20): bulk-fill composite (Filtek™ Bulk fill) using a bulk technique, group II ( = 20): bulk-fill composite (Filtek™ Bulk fill) using an incremental layering technique, group III (negative control) ( = 10): gutta-percha was kept intact at the access orifice and covered with a nail polish, and group IV (positive control) ( = 10): gutta-percha was kept intact at the orifice.
