Background The duration of orthodontic treatment is often a significant deterrent for patients when considering conventional mechanics, which can be time-consuming. Photobiomodulation (PBM) utilizes visible red to near-infrared wavelengths of light frequencies to expedite orthodontic treatment time. Objective To investigate the effect of three Lig...

Aim To determine stresses generated in the posterior teeth region by two different self-ligating systems, 3M Unitek SmartClip and Damon Q Self-ligating brackets, using the finite element method (FEM). Methodology Computed tomography (CT) scan of maxilla was taken using Mimics software, and the Dicom data were imported into Hypermesh 13.0 software...

Background and Aim One of the main reasons that patients seek orthodontic treatment is aesthetics. Unfortunately, treatment with fixed orthodontic appliances can at times increase the chances of developing white spot lesions on the surfaces of teeth, thus creating a new aesthetic issue for the patient. The prevalence of white spot lesions (WSL) rep...

Introduction: In adult patients seeking orthodontic treatment, some common reasons include unesthetic appearance and functional impairment such as difficulty in speaking or breathing. Thus, malocclusion and orthodontic care have become a Quality of Life (QoL) issue. Aim: To investigate the oral health-related quality of life in adults before and af...

Aim and objective: The aim of this finite element method (FEM) study was to assess the safety of 125-150 Hz vibrational frequency electric toothbrush on teeth and associated structures. Materials and methods: A three-dimensional (3D) geometric model of entire skull having maxilla, mandible, and their dentitions was created using a computed tomog...

Introduction Fluoride agents to prevent white spot lesions are used often during orthodontic treatment. The beneficial effects of fluoride, when consumed within permissible limits on dental structures, are well known. Their implications on underlying biological tissues, however, are unknown. Mouthwashes and dentifrices with fluorides are associated...

Aim To analyze the degree of corrosion of nickel titanium arch wires in patients with and without exposure to fluorides. Material and methods This was an ex vivo study comprising of 60 subjects undergoing fixed orthodontic treatment. Group 1(controls) comprised of 30 sets of new unused NiTi wires and unused 11, 15 brackets, Group 2(patients) compr...

Objective: The aim of the study was to analyze the displacement and stress pattern in periodontal ligament (PDL) of palatally impacted canines (PIC) lateral incisors (LI) and first premolars (FP) adjacent to the impacted teeth when different magnitudes of orthodontic extrusion forces were applied along with variation in the inclination of the impa...

Objective To investigate levels of nickel and chromium in gingival crevicular fluid from subjects undergoing orthodontic treatment with and without using fluoridated toothpaste and mouthwash over a 6-month period. Materials and methods Sixty subjects divided into two groups of 30 each served as the experimental group with and without using fluorid...

Objective Orthodontic treatment aims at improving the perceived aesthetics; hence knowing which characteristics play a significant role in determining aesthetics is an important orthodontic objective. The aim of this study was to evaluate among laypersons, general dentists and orthodontists the importance of dental versus facial aesthetics. Materi...

Résumé Objectif Le traitement orthodontique tend à améliorer l’apparence esthétique ; par conséquent, connaître quelles en sont les caractéristiques significatives est un objectif important en orthodontie. Cette étude visait à évaluer dans trois catégories, profanes, dentistes et orthodontistes, la part de l’esthétique dentaire versus celle de la...

Objectives: This study aimed to establish cephalometric norms for an Omani population of Arab descent and to compare these with established cephalometric values for Caucasians. Methods: This cross-sectional study was conducted at the Military Dental Centre and Oman Dental College in Muscat, Oman, between May 2014 and October 2016. A total of 150...

Introduction: Application of orthodontic forces to a tooth is characterised by extensive macroscopic and microscopic changes during remodelling which occurs in the Periodontal Ligament (PDL), alveolar bone and gingiva. This occurs mainly due to the local stresses and strains subjected on the supporting tissues. As direct measurement of these parame...

Introduction: Class III malocclusion exists when the mandibular molar occludes mesial to the maxillary molar as a result of a skeletal discrepancy i.e., normal maxilla and protruded mandible, retruded maxilla and a normal mandible or a retruded maxilla and a protruded mandible, concomitant with or without a dental discrepancy, or due to the functio...

Aim: The aim of the study was to analyze the stress distribution and displacement of palatally impacted maxillary canine and its adjacent teeth (lateral incisor and first premolar) when orthodontic extrusion forces were applied on the impacted canine. Materials and methods: A three-dimensional finite element model of a maxilla containing a palatall...

Aim To determine the actual position of point A by performing incisor inclination correction in class II division 2 and class III. Also, to determine the relation between the degree of incisor inclination correction and anteroposterior movement of point A by studying pre- and postalignment lateral cephalograms. Materials and methods The pre- and p...

Dentistry is an ever changing field and there has always been a quest to find procedures and techniques that are fast more effective, convenient and patient friendly. The introduction of light amplification and stimulated emission of radiation technique in both medicine and dentistry has brought a sea change in these fields. Lasers have numerous ap...

Aim The purpose of this investigation was to (1) compare the credibility of four recently introduced cephalometric measurements in assessing the antero-posterior jaw relationship; (2) To assess the correlation between various measurements used for assessment of antero-posterior discrepancy, including Yen linear, Yen angle, W angle and Pi angle. Ma...
