Aim: The purpose of this study is to Clinically assess the impact of 5.25% sodium hypochlorite enamel deproteinization on the orthodontic bracket survival rate during the initial phase of fixed appliance therapy.
Materials and Methods: Twenty individuals in the 15–30 age range with full permanent dentition were split into two groups. Group B (Left upper and Left lower quadrant): the enamel surface is prepared with 5.25% sodium hypochlorite before bonding (Total number of brackets – 190); Group A (Right upper and Right lower quadrant): brackets were bonded without enamel deproteinization. Up until the point of leveling and alignment, the bond failure rate of the brackets was monitored and evaluated every few months. The bracket failure rate is evaluated using Pearson's Chi-square test. The preset P value was set at < 0>
Results: Among the 18 (4.7%) bracket failures that occurred throughout the study period, 4 (2.1%) were debonded in the experimental group, while 14 (7.4%) occurred in the statistically significant control group (p=0.016). There were 8 debonded brackets in the maxillary arches (4.2% failure rate) and 10 debonded brackets in the mandibular arches (5.3% failure rate) (p = 0.629). Bracket failure rates were higher for posterior (premolar) brackets (7.8%) than anterior brackets (2.9%) (p=0.334).
Conclusion: The use of 5.25% sodium hypochlorite prior to attaching orthodontic brackets using Transbond XT might be considered a favorable method for enhancing the bond survival rate.
