Agreement of the clinician's choice of archwire selection on conventional and virtual models.

Objectives: To compare archwire selection on dental casts with archwire selection using a three-dimensional (3D) software program (OrthoAid) and assess agreement between clinicians.

Materials And Methods: The best-fitting archwires were selected for dental casts of 100 patients with malocclusion using two approaches by three orthodontists. The first method was to visually determine the fitness of five preformed nickel titanium archwires to the arch form on a dental cast (subjective method).

Effect of Low-intensity Pulsed Ultrasound on Postorthognathic Surgery Healing Process.

Background: Orthognathic surgery can cause discomforts such as pain, inflammation, and edema. One of the challenges is bone regeneration at surgery area. The aim of this study is to evaluate the effect of low-intensity pulsed ultrasound (LIPUS) therapy on bone regeneration and pain relief after surgery.

Endodontic repair in immature dogs' teeth with apical periodontitis: blood clot vs plasma rich in growth factors scaffold.

Background/aim: Different types of scaffolds have been suggested for endodontic repair procedures. The aim of this study was to compare the outcome of procedures using blood clot vs plasma rich in growth factors (PRGF) scaffold in immature teeth with apical periodontitis in dogs.

Materials And Methods: In this in vivo animal study, 20 teeth (30 canals) with open apices were divided into two groups (n = 12): (1) blood clot and (2) PRGF.
