COMPARISON OF FAILURE RATE OF TEMPORARY ANCHORAGE DEVICES PLACED WITH PLATELET RICH PLASMA AND PLACEBO OVER SIX MONTHS: A SPLIT MOUTH RANDOMIZED CLINICAL TRIAL.

Background: The aim of this in vitro research was to compare and evaluate the stability of TADs coated with PRP over 6 months. TAD stability is essential for the long-term success of orthodontic treatment. PRP has become a valuable adjunct to promote healing in many procedures of oral surgery.

Comparative bond failure rate of orthodontic brackets when bracket base is treated with micro-abrasive blasting . acid etching: eighteen month randomized control trial and scanning electron microscope study.

Background: The aim of this study was threefold. Firstly, it aimed to introduce and detail a novel method for chemically etching the bases of stainless-steel orthodontic brackets. Secondly, the study sought to investigate the structural alterations within the brackets' microstructure following chemical etching compared to those with sandblasted bases, using electron microscopy analysis.

Comparison of in vivo failure of precipitation-coated hydroxyapatite temporary anchorage devices with that of uncoated temporary anchorage devices over 18 months.

Introduction: The objective was to compare the stability of hydroxyapatite-coated (HA) temporary anchorage devices (TADs) with uncoated TADs.

Methods: Maxillary arches of 92 patients with Class II Division 1 malocclusion requiring premolar extractions were randomly distributed to receive both types of Ti-6Al-4V alloy TADs by a single operator. TADs were replicas of each other except for the HA precipitation surface coating of the threaded part.

Using otolith and body shape to discriminate between stocks of European anchovy (Engraulidae: Engraulis encrasicolus) from the Aegean, Marmara and Black Seas.

European anchovy, a small pelagic fish, plays a significant role in the blue economy, with remarkable commercial, ecological and culinary values. In this study, the variability in the shapes of the body and sagitta otoliths was examined to identify the different anchovy stocks in the Black Sea (26.5°E-39.
