Effect of resveratrol on bone formation in the expanded inter-premaxillary suture: early bone changes

TANCAN UYSAL

Objective –The aim of this study was to evaluate the effects of local resveratrol (RSVL) administration on bone formation in response to expansion of the interpremaxillary suture, in rats. Material and Methods – Twenty 50- to 60-day-old male Wistar rats were separated into two equal groups. Both groups were subjected to expansion, and 30 cN of force was applied to the maxillary incisors with helical-spring. Twenty-four hours after appliance placement, single-dose 10 lmol ⁄ kg RSVL in the dimethylsulfoxide (DMSO) was injected to the inter-premaxillary suture in the experimental group. In ...Daha fazlası

Resonance frequency analysis of orthodontic miniscrews subjected to light-emitting diode photobiomodulation therapy

TANCAN UYSAL

The aim of this prospective experimental study was to evaluate the effect of light-emitting diode (LED) photobiomodulation therapy (LPT) on the stability of immediately loaded miniscrews under different force levels, as assessed by resonance frequency analysis (RFA). Sixty titanium orthodontic miniscrews with a length of 8 mm and a diameter of 1.4 mm were implanted into cortical bone by closed flap technique in each proximal tibia of 15 New Zealand white adult male rabbits (n = 30). The animals were randomly divided into irradiated and control groups under different force levels (0, 150, and 3 ...Daha fazlası
