Location of External Root Resorption of Upper Permanent Incisors Adjacent To Impacted Maxillary Canines: Assessment By Cone Beam Computed Tomography
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 1
Abstract
Impacted maxillary canines are common in orthodontic practice. Untreated impacted maxillary canines interfere with the alignment of adjacent teeth and can cause irreversible damage of external root resorption of adjacent teeth especially incisors. The purpose of the study was to investigate the location of root resorption associated with ectopic eruption of maxillary canines. CBCT scans were taken using NewTom GiANO cone beam computed tomography machine (CBCT). Location of the root resorption was taken in relation to the long axis of the involved tooth. In this study, a total of 53 impacted canines were investigated and it was found that 18 incisors were resorbed, which included 16 lateral incisors and 2 central incisors. Root resorption on permanent lateral incisors was located primarily in the middle third of the root (50.0 per cent), followed by the apical third of the root (25 per cent), cervical third of the root (18.7 per cent) and apical tip (6.3 per cent). In central incisor resorptions, it was found in the middle third (50 per cent) and apical third (50 per cent). The main location of root resorption on lateral incisors was primarily on lingual side (62.5 per cent) followed by buccal (25 per cent), distal (6.25 per cent) and apical (6.25 per cent). In case of central incisors, the main location was lingual (50 per cent) and distal (50 per cent).Thus CBCT provides accurate information regarding location of root resorption on incisors associated with impacted canines which is very beneficial and important before treatment plan
