Abstract
Background: The removal methods of adhesive resin remain a subject of debate among researchers regarding the most effective approach for reconditioning debonded brackets from the tooth.
Objectives: The aim of this study was to evaluate the micro sandblaster and direct flame technique for removing adhesive remnants from debonded orthodontic metal bracket bases.
Method: The research design was experimental and involved comparing the micro sandblaster and direct flame technique in removing adhesive remnant using purposive sampling. Thirty (30) metal brackets were divided into two groups and soaked for 24 hours in an incubator before applying the two methods of removal. The samples were examined in optical microscopy, and the areas of adhesive remnants were analyzed and measured as a percentage of the digital images using the ImageJ analysis software function. Pixels were converted into millimeters (mm). Statistical analyses, including Shapiro-Wilk Test, Levene’s Test, and T-Test for Independent samples were conducted.
Results: The micro sandblaster group exhibited the lowest mean value at 1.518 mm +1.159 (mean + standard deviation), while the direct flame group showed the highest value at 2.264 mm +1.262. The Levene’s Test result was 0.079, and the T-Test for Independent Samples yielded a p-value of 0.103 which exceeded the predetermined significance level of 0.05.
Conclusion: The results of this study indicate that the micro sandblaster and direct flame techniques for removing adhesive residues from debonded metal brackets showed statistically insignificant differences. Either of these methods may be a viable approach for operators to use when reconditioning dislodged brackets.
