INTRODUCTION: Bonding failure during orthodontic treatment is always a great threat and challenge for the orthodontist since frequent bond failure can prolong the treatment duration and affect the compliance of the patient. Variables that influence the success of bonding include the procedure, the adhesive, sealants, brackets, light that induces polymerization. Major challenge during bonding procedure is to prevent moisture contamination since conventional adhesives are hydrophobic which fail to adhere to the moist surface. To overcome this issue, many techniques have been developed, among which introduction of hydrophilic primers for moisture contamination is the commonest one. PURPOSE: The purpose of the study was to comparatively assess the clinical bond failure rates with two moisture insensitive primers, Bracepaste MTP and Transbond MIP. MATERIALS AND METHODS: 22 patients, 440 teeth were included in the study, out of which 220 teeth were bonded with Bracepaste MTP and 220 teeth were bonded with Transbond MIP. This study was conducted in a split mouth fashion in which the quadrants and arches are equally distributed among patients. Various comparisons have been assessed with the materials like between the arches, between teeth, between anterior and posterior region and adhesive remnant index. RESULTS: In general there was no statistical significant difference in the failure rate of two moisture insensitive primers (p-0.160). On inter ach comparison Bracepaste MTP showed high failure rate in both the arches which was statistically insignificant, while Transbond MIP showed significant failure rate in mandibular arch with P value of 0.018. Both the groups showed increased failure rate in mandibular 2nd premolar which was clinically significant. CONCLUSIONS: Even though Bracepaste MTP showed increased failure rate than Transbond MIP, it can be effectively used in day to day practice since the difference is not statistically significant.
