Dental press j. orthod. (Impr.); 25 (1), 2020
ABSTRACT Objective: This study proposed to investigate the influence of catastrophizing and others factors related to pain during orthodontic treatment. Methods: 27 patients with 0.022 x 0.028-in Straight-wire brackets were evaluated during alignment and leveling phase with nickel-titanium wires. Visua...
Effects of restraint stress and high-fat diet on osseointegration of titanium implants: an experimental study
Braz. oral res. (Online); 34 (), 2020
Abstract This study aimed to investigate the effects of chronic restraint stress (RS) and a high-fat diet (HFD) on the osseointegration of titanium implants in a rat model. After the surgical insertion of titanium implants into the metaphysis of the tibial bone, the rats were randomly divided into four e...
