AIM This study evaluated the behavior of oral epithelial cells in contact with orthodontic appliances. METHODS Oral epithelial cells of clinically normal buccal mucosa were obtained by liquid-based exfoliative cytology from 22 orthodontic patients. The following regions were evaluated: a) oral mucosa exposed to friction from orthodontic brackets; b) oral mucosa exposed to friction from the tu...

INTRODUCTION The choice of brackets, bands and wires is a very important aspect of orthodontic treatment. Stainless steel prevailed for a long time, but new alloys and resources have emerged to diversify the orthodontic wire mechanics. OBJECTIVE This study aimed to investigate the profile and materials used by orthodontists practicing in the State of São Paulo, Brazil. METHODS A questionnai...

statement of problem: although different types of aesthetic brackets are introduced to orthodontic profession to reduce the complaints about the metallic braces, little studies have been done to assess patient's views regarding the attractiveness and acceptance of such brackets.   objectives: the goal of this study was to evaluate the perceived acceptability, beauty and value of different ortho...

It is a commonly held misconception among Irish dentists that only minor malocclusions can be treated with lingual appliances. This article demonstrates the use of contemporary completely customised lingual orthodontic appliances to treat a diverse range of malocclusions, to a satisfactory level, and thereby may disabuse clinicians of the belief that only minor malocclusions can be treated with...

The aim of this paper is to familiarize the readers with some of the clinical considerations necessary to ensure successful use of mid-palatal implants. Both surgical and technical aspects will be discussed along with a description of impression techniques used.

OBJECTIVE Increased number of adult patients requesting orthodontic treatment result in bonding bracket to ceramic restorations more than before. The aim of this study was to evaluate and compare the shear bond strength of orthodontic brackets bonded to two types of ceramic bases with conventional orthodontic bonding resin and a new nano-filled composite resin. MATERIALS AND METHODS Twenty fo...

INTRODUCTION Therapy with fixed orthodontic appliances starts with bracket bonding and ends with debonding of brackets, leaving enamel surface varied. Objective The aim of this pilot study was to examine enamel surface before and after debonding of orthodontic brackets by the use of scanning electron microscopy (SEM). METHODS Epoxy replicas of four patients' premolars indicated for therapy wi...

BACKGROUND Magnetic resonance imaging (MRI) has been used to study configurations of speech organs in the resting state. However, MRI is sensitive to metals, and numerous types of metallic appliances, most of which have a large magnetic susceptibility, are used in orthodontic treatment and may cause severe artifacts on MRI. We have developed techniques for obtaining MRI movies of the oral regio...

objective: orthodontic wires should have high resistance against corrosion in the oral environment. since the effect of ph on corrosion has been well recognized, this study sought to assess and compare the electrochemical corrosion of orthodontic brackets and wires of different brands in acidic artificial saliva.   methods: this in vitro experimental study was conducted on 24 mandibular central...

Background: New materials that are introduced in operative dentistry can potentially have orthodontic applications. One of the most important advances in the dental material field is the application of nanotechnology to resin composites. Recently, new fillers with size ranging from approximately 5-100 nm have been developed. These materials could thus be considered as precursors of nanocomposit...
