A COMPARATIVE EVALUATION OF EXTERNAL APICAL ROOT RESORPTION IN PATIENTS TREATED WITH DAMON BRACKET SYSTEM AND CONVENTIONALMBT BRACKET SYSTEM- A RETROSPECTIVE STUDY

Background: Resorption of the external apical root is a common iatrogenic side effect of orthodontic therapy (EARR). The loss of cementum and dentine is caused by root resorption, which can be a normal or pathologic process. A complicated combination of individual biology and mechanical forces is assumed to be the cause. Aims &Objectives: The purpose of this research was to assess the degree of external apical root resorption (EARR) in patients treated with the Damon self-ligating bracket system to those treated with the conventional MBT bracket system. Methods: For the study, twenty patients were divided into two groups. Ten patients were treated with MBT equipment in Group I. Damon self-ligating appliances were used to treat ten patients in Group 2. The Levander and Malmgren scores were used to assess root resorption on periapical radiographs of the maxillary incisors at the completion of orthodontic therapy. The chi-square test was used to compare root resorption between groups. Results: There was no significant difference in the degree of root resorption between the two groups, according to the findings. Conclusion: Non-extraction therapy with Damon self-ligating or standard preadjusted equipment resulted in similar root resorption, according to the findings.
