OBJECTIVE To investigate the influence of caries infiltrant preconditioning on the shear bond strength of orthodontic resin cements on sound and demineralized enamel. MATERIALS AND METHODS  Stainless-steel brackets were bonded to sound or artificially demineralized (14 d, acidic buffer, pH 5.0) bovine enamel specimens using a resin cement or a combination of caries infiltrant preconditioning ...

introduction: the current study investigated the pulp response to electric pulp testing (ept), before, upon initiation and one month after the start of orthodontic tooth movement. methods and materials: a total of 402 anterior teeth from 39 patients (mean age of 16.8±2.7 years) were examined in this non-controlled prospective study. the aligning forces were administered using initial niti archw...

OBJECTIVE To evaluate the effect of chlorhexidine-thymol varnish alone, its combination with chlorhexidine-fluoride containing dentifrice and fluoride varnish on oral hygiene and caries prevention in orthodontic patients. STUDY DESIGN Sixty patients, aged 12-18, with orthodontic fixed appliances were randomly assigned into three groups as follows: Group 1 (n=20): 1% chlorhexidine and 1% thymo...

BACKGROUND Different in-vitro studies have reported various results regarding shear bond strength (SBS) of orthodontic brackets when SEP technique is compared to conventional system. This in-vivo study was designed to compare the effect of conventional acid-etching and self-etching primer adhesive (SEP) systems on SBS and debonding characteristics of metal and ceramic orthodontic brackets. MA...

The diagnosis of Amelogenesis Imperfecta (AI) in a young patient can present many complex restorative and orth odontic challenges for the pediatric dentist. These patients have traditionally been treated with a combination of extractions, composite bonding, stainless steel crowns, adhesive castings, over-dentures, and porcelain veneers. They often have anterior open bites or vertical deep bites...

There is an increase in the number of dentists using orthodontic treatment for anterior tooth alignment. This is either combined with additive bonding or interproximal reduction; knowing "when to" and "how much" requires an understanding of the anterior ratio. This case report explains how to use the anterior ratio to help provide optimal aesthetics and function for the ortho-restorative patien...

Orthodontic appliances often provide good retention sites for oral microorganisms. This leads to a high cariogenic challenge in saliva. The purpose of this study was to evaluate saliva Streptococcus Mutans and Lactobacilli levels in different 5 phase on 24 patients need to both removable and fixed orthodontic application. So we had a possibility to determinate of the S. Mutans and Lactobacilli ...

Objectives: To review the failure rates of molar tubes and effect tube base design, adhesive type, bonding technique on tubes. Data: The revolution greatly impacted fixed orthodontic appliance treatment by reducing chair-side time improving patient comfort. Even with many advantages bonding, clinicians sometimes hesitate to use due their rates. Sources: Internet sources, such as Pubmed Google S...

The fabrication of electroplated planar copper microcoils for telemetric orthodontic applications is presented. A set of microcoils with overall dimensions of 2 × 2.5 × 0.5 mm3, track widths down to 5 μm and turn numbers up to 35 were fabricated on glass substrates. The coils were electrically characterized and assembled via flip-chip bonding onto a stress-mapping CMOS chip for smart orthodonti...

Braces as foreign bodies in the mouth carry a risk of side effects and toxicity to the human body. This article presents the results indicating the possible toxic effects of tools used for cleaning the enamel after the completion of orthodontic treatment. The studies were carried out in vitro. The procedure of enamel etching, bonding orthodontic metal brackets, and enamel cleaning after their r...
