OBJECTIVE To find a correlation between the severity of enamel microcracks (EMCs) and their increase during debonding and residual adhesive removal (RAR). MATERIALS AND METHODS Following their examination with scanning electron microscopy (SEM), 90 extracted human premolars were divided into three groups of 30: group 1, teeth having pronounced EMCs (visible with the naked eye under normal roo...

OBJECTIVE The objective of this study was to assess, in vitro, the influence of bleaching gel and the use of desensitizing agent over bond strength of ceramic brackets bonded to bovine enamel. METHODS One hundred bovine incisors were selected and randomly divided into five groups (n = 20): Group 1, control group (without bleaching); Group 2, bleached with 35% hydrogen peroxide; Group 3, bleac...

The aim of this study was to analyse the peel resistance of silver plated wires examined in an intraoral setting. In this study, a 0.016 × 0.016 inch silver plated stainless steel wire and a 0.016 × 0.016 inch Teflon-coated nickel-titanium wire were investigated. The brackets of ceramic and stainless steel were bonded to the first and second bicuspids of two subjects. We investigated peel resis...

The aim of this study was to evaluate the shear bond strength (SBS) of polycrystalline ceramic brackets (PCB) bonded after bleaching treatment using different composite resins and enamel etching times. A total of 144 bovine incisors were randomly divided into two study groups (n = 72, each) as follows: G1, enamel bleached with 35% hydrogen peroxide, and G2 (control group), enamel unbleached. Af...

The purpose of this study was to test the hypothesis that porcelain surface finishing, ie, low- and high-fusing porcelain, has an effect on the amount of force required to debond orthodontic brackets. A total of 20 high-fusing and 20 low-fusing porcelain specimens were prepared, polished, and bonded with standard edgewise brackets using a suggested porcelain bonding protocol. The brackets were ...

ABSTRACT
 Orthodontics, in today’s contemporary world, is focused mainly on aesthetics. Most of the adult patients are reluctant to orthodontic treatment due their un-aesthetic appearance. To answer such problems several options available, ranging from aesthetic brackets, made tooth-coloured plastic or ceramic, another option Invisalign, which restricted only certain kinds simple malocclus...

This study’s aim is to determine the accuracy and precision of bracket slot height in MBT 0.022″ ceramic brackets. Five brackets from 11 different systems (n = 55) were scanned using micro-computed tomography (micro-CT). The was measured at face (external) base (internal) slot. Data analyzed a One-Sample t-Test, Paired t-Test. lowest external seen OrthoCare Purity® 0.02264″ (2.9%), greatest TOC...
