Introduction: The biggest challenge that orthodontist face in the clinical practice is debonding of the brackets. The best way to avoid bond failure is to adhere strictly to the rules of good bonding. Aims and Objectives: Aims and objectives of the study were to measure shear bond strength of orthodontic brackets which were rebonded using different tooth surface reconditioning methods that are ...

OBJECTIVE To compare the conventional etching and primer method (CEP) and the self-etching primer method (SEP) in rebonding brackets. METHODS Forty human maxillary second premolars extracted for orthodontic purpose were randomly divided into 4 equal groups. Group 1 and Group 2 were bonded using the CEP method; Group 3 and Group 4 using the SEP method. All the brackets were debonded and 40 new...

OBJECTIVE The aim of this study was to compare the shear bond strength (SBS) of resin modified glass ionomer (RMGI) and composite resin for bonding metal and ceramic brackets. MATERIALS AND METHODS Eighty-eight human premolars extracted for orthodontic purposes were divided into 4 groups (n=22). In groups 1 and 2, 22 metal and ceramic brackets were bonded using composite resin (Transbond XT),...

A good adhesive is an important factor to consider in orthodontic bonding. Frequent bracket failure prolongs treatment duration and causes inconvenience to patient and operator. This study aimed to compare the effectiveness of two bonding agents, i.e. the self etching primer (SEP) and the conventional etch and bond (CEB) by monitoring the incidence, time and sites of bracket failure. Eighty ort...

With COVID-19 declared as a worldwide pandemic, nationwide lockdown was implemented overnight in India on March 24, 2020. This posed many challenges to the orthodontic practice that requires periodical and regular appointments ensure appropriate results. Since treatment often takes long period of time ranging from 12 18 months or even longer, patients undergoing Orthodontic were affected instit...

The purpose of this research was to investigate the torque capacity of active and passive self-ligating brackets compared with metallic, ceramic, and polycarbonate edgewise brackets. Six types of orthodontic brackets were included in the study: the self-ligating Speed and Damon2, the stainless steel (SS), Ultratrimm and Discovery, the ceramic bracket, Fascination 2, and the polycarbonate bracke...

AIM To evaluate and compare the shear bond strength of metal brackets bonded to ceramic surfaces using different conditioning methods and to assess the site of bond failure after debonding. MATERIALS AND METHODS A total of 70 ceramic surfaces were produced with uniform shape, size and composition. The samples were divided into 7 groups (each of 10 samples). Group 1 was the control group (untr...

OBJECTIVE To determine the shear bond strength of orthodontic brackets using color change adhesives that are supposed to aid in removing excess of bonding material and compare them to a traditional adhesive. METHODS Ninety metallic and ninety ceramic brackets were bonded to bovine incisors using two color change adhesives and a regular one. A tensile stress was applied by a universal testing ...

Previous studies have shown that the size of the foil mesh and surface area of the bracket base correlated to bond strength to tooth enamel. The purpose of this study was to investigate the in vitro shear bond strength (SBS) of orthodontic brackets with 80 and 100 gauge mesh bases as well as mini and standard size bases. Eighty extracted human premolar teeth were randomly allocated into four gr...
