Abstract

Root resorption is a side effect which cannot be prevented in orthodontic treatment. External apical root resorption (EARR) causes root shortening. The purpose of this study is to assess the prevalence of the degree of EARR in the incisors between maxillary and mandible before and after orthodontic treatment in patients with non-extraction cases. This research is an analysis of a cross-sectional study conducted on samples namely panoramic radiographs of patients before and after orthodontic by using the modification of Lavender and Malmgren index and Linge and Linge method. Wilcoxson test and Chi-square test was used for statistical analysis. Samples amounted to a total of 400 incisor teeth which have received orthodontic treatment. Results shows that of the 400 incisor teeth studied, the results found were 5 incisors (1.25%) with mild EARR (score 1), 368 incisors (92%) had moderate EARR (score 2) and as many as 27 incisors (6.75%) had severe EARR (score 3). The incisors with extreme EARR (score 4) is 0%. Conclusion, the EARR experienced by incisors is on score 2 as much as 92% and there are no incisors (0%) experienced extreme EARR (score 4).
