The effect of experimental tooth movement on nerve fibers immunoreactive to calcitonin gene-related peptide (CGRP) and to protein gene product (PGP) 9.5 were studied, as well as the coincidence of these responses with changes in blood vessel density and distribution in the periodontal ligament (PDL) and pulp of young Wistar rats. The first right maxillary molar was moved mesially by an orthodon...

Aim To evaluate the effect of red wine consumption or its polyphenols on inflammation/resorption processes associated with apical periodontitis in rats. Methodology Thirty-two three-month-old Wistar rats had induced four first molars and were then arranged into groups: control (C)—rats periodontitis; (W)—rats receiving 4.28 ml/kg wine; resveratrol+quercetin (R+Q)—rats a solution containing 1.00...

BACKGROUND To test the null hypothesis that there is no difference in the apical root resorption seen after orthodontic treatment with the conventional brackets and the self-ligating brackets. METHODS Pre-treatment and post-treatment periapical radio-graphs of 70 patients, (35 treated with the Damon3 0.022" bracket and 35 with the 0.022" 3 M bracket) were studied. The long cone paralleling te...
