“…For gender distribution, the majority of the CBCTs were for females (78%) that were similar to the percentage reported in previous studies [2,15,17,20]. It was also consistent with what has been documented in the literature as a greater prevalence of IMC in females than in males [1,4,21]. Such difference could be attributed to the variations in genetics or overall growth and development of craniofacial structures between the two genders [11].…”

Objectives. The aim of this retrospective study was to determine the position of the impacted maxillary canine (IMC) and then to inspect the frequency, location, and extent of the consequent root resorption (RR) of the adjacent teeth by using CBCT. Materials and Methods. Forty-one patients aged 12-68 who have 56 IMC detected on CBCT images were retrospectively examined in 3D. The canine position was determined by assessing the side of impaction, buccopalatal location, the distance of the canine cusp tip to the midline and to the occlusal plane, and canine angulation to the midline. RR of adjacent teeth was analyzed by investigating the nearest location of ectopic canine to adjacent teeth in horizontal and vertical dimensions in addition to measuring the degree of RR. Results. Twenty-seven (48.2%) impacted canines were on the right side, and 29 (51.8%) were on the left. Most of these teeth 31 (55.4%) were located palatally, while buccal impaction was seen in only 13 (23.2%) canines and 12 (21.4%) were located centrally. The mean distance of the ectopic canine cusp tip to the occlusal plane was significantly higher in males (14.4 mm) than in females (10.7 mm). RR was seen in 9 central incisors (31.03%) and 21 lateral incisors (41.17%) as well as one case in the first and second premolar. This RR was slight for all the adjacent central incisors and premolars. Conclusions. IMC is more frequent in females, palatally and apically. When left untreated, it may cause RR of some of the adjacent teeth with various degrees, however, with no gender preference.

“…Recent studies have compared canines presenting with buccal and palatal impaction against control groups. 10,11,35 However, there are conflicting results. Kim et al reported that impacted maxillary canines in a buccal position caused more resorption in adjacent teeth than those in palatal positions and the relationship was statistically significant.…”

“…There was, however, no noted statistical significance. 11 As these studies were conducted in different geographic regions, the differences in the results could be attributed to demographic variability as it has been previously reported that the variability of a population influences the incidence of resorption in any tooth or individual in relation to displaced maxillary canines. 13 When comparing impacted maxillary canines according to the four sectors of mesiodistal location, it was noted that the lateral incisor resorption rate increased with greater canine proximity to the maxillary midline.…”

“…They can also result in migration of adjacent teeth, cyst formation, pain and infection. 3,8 However, the most common significant problem is root resorption of adjacent teeth, [8][9][10][11] particularly affecting the root of the maxillary lateral incisor. 12,13 Although less common, resorption may also affect the roots of the central incisors and premolars.…”

Objective The spatial position of a canine can affect the level of proximal root resorption and the success of orthodontic treatment. The aim of this study was to examine the mesiodistal and vertical position of impacted maxillary canines and to assess their relationship with the lateral incisor by using cone beam computed tomography (CBCT). Material and method One hundred and sixty-nine CBCT scans of patients presenting with maxillary impacted canines were included in the study. The buccopalatal, mesiodistal (classified as sectors I, II, III, IV from distal to mesial) and vertical (cervical, middle, apical) position of the maxillary impacted canines were determined. The positional effect on the morphology (width, length, and depth) and resorption was assessed on the roots of the maxillary lateral incisors. Obtained data were statistically analysed by using Student t-test, the Mann Whitney U and Chi-Square tests. Results Of the maxillary impacted canines, the 34.72% that had associated resorption on the adjacent lateral incisors were buccally positioned, and 65.28% were palatally positioned. While 45.58% of sector I impacted maxillary canines were buccally positioned, 68.31% of sector IV impacted maxillary canines were palatally positioned. Furthermore, there was a statistical significance between the mesiodistal position and palatal or buccal maxillary canine impaction (p < 0.05). In addition, the vertical position of the impacted maxillary canines was also related to their mesiodistal and buccopalatal positions (p < 0.05). Conclusion While all maxillary impacted canines had the potential to cause lateral incisor resorption, there was no close relationship related to the canine’s buccopalatal, mesiodistal and vertical position. Nevertheless, if an impacted maxillary canine migrated towards the midline, the buccopalatal and vertical position of the tooth changed from buccal to palatal and cervical to apical, respectively.

“…In one study (20) the angulation of the canine was steeper on the labial side than on the palatal side, but root resorption of adjacent laterals was not different. There were no statistically significant differences in the amount of root resorption of the laterals when the canine was evaluated according to localization and angulation .…”

CBCT assessment of impacted canine improves canine localization to adjacent teeth and provides higher level of confidence in the treatment plan compared to 2D images. However, there is conflicting evidence to support using CBCT as a routine first-line imaging method in patients with impacted maxillary canine and incisor root resorption. Consequently, there are doubts regarding difference in diagnostic and treatment planning between the use of conventional 2D and CBCT sets. Therefore, the present review will attempt to summarize the new aspects regarding the benefits of three-dimensional (3D) diagnostic techniques (cone-beam computed tomography, CBCT), including the accuracy of localization of impacted canine and the detection of the degree and location of root resor ption of maxillary incisors.
