Force level of small diameter nickel-titanium orthodontic wires ligated with different methods.

Background: The aim of this study was to compare the deflection force in conventional and thermally activated nickel-titanium (NiTi) wires in passive (Damon Q) and active (Bioquick) self-ligating brackets (SLB) and in conventional brackets (CB) tied by two different methods: elastomeric ligature (EL) and metal ligature (ML).

Methods: Two wire diameters (0.014 and 0.

Low-Level Laser Action on Orthodontically Induced Root Resorption: Histological and Histomorphometric Evaluation.

Studies have been conducted to develop a means of preventing, controlling or reducing orthodontically induced root resorption. Phototherapy has demonstrated effectiveness as an anti-inflammatory and, considering the inflammatory origin of this pathology, this study evaluated the effects of laser on root resorption. The research was conducted among 54 80-day-old male Wistar rats, with weights of 280 ± 40 g.
