POSSIBLE CAUSES OF ROOT RESORPTION IN ORTHODONTIC TREATMENT

In this study, the presence and possible causes of external root resorption were investigated by comparing pre- and post-treatment panoramic radiographs. Also, degrees of root resorption were investigated. In this study, external root resorption and its degree were examined in panoramic radiographs of patients who had fixed orthodontic treatment between January 2015 and March 2020. Root resorption was determined in only post treatment panoramic radiographs by comparing pretreatment panoramic radiograph. Anterior and posterior region resorption score of both jaws was calculated for each individual. The relationship between root resorption, age, gender, duration of treatment, types of treatment and malocclusion has been investigated. 560 patients (358 females and 202 males) were included in the study and the average age was 14.2. Root resorption scores of mandibular teeth were higher in males (p<0.01). A positive correlation was found between the treatment duration and root resorption scores of maxillary anterior teeth (p<0.01). Root resorption scores of all regions were higher in orthodontic treatment with extraction (p<0.01). There was no significant relationship between age and root resorption score (p>0.05). Long-term orthodontic treatment and orthodontic treatment with extraction increase the prevalence of root resorption. Panoramic radiograph is an important diagnostic tool in the detection of root resorption due to orthodontic treatment.
