Patterns of Maxillary Canine Impaction in Iraqi Population

Abstract

To investigate the prevalence of maxillary canine impaction and whether the impacted canine cases have had a potentially good or poor prognosis if interceptive treatment was practiced at earlier ages. Material and Methods: 1755 panoramic radiographs of patients, aged 13 to 60 years, attending the University of Babylon, College of Dentistry for the period from November 2016 to July 2018 were collected and assessed for the presence of impacted maxillary canines. Subsequently, four suggested prognostic factors for each impacted canine were analyzed and recorded. Results: The prevalence of maxillary canine impaction was 119 (6.78%) with 89 unilateral impaction and 30 bilateral impaction resulting in a total of 149 impacted canines. Regarding the gender, impaction was more evident in females 70 than in males 49 with no statistical significant difference. For the side, impaction was more prevalent on the left (77) than on the right (72), also with no statistical difference (p>0.05). Following the analysis of the four prognostic factors, most of the cases, 117 (78.5%) had at least one prognostic factor to be poor. Although 82 (55%) of the cases had at least one prognostic factor to be good, only 4 had all the prognostic factors to be good. Conclusion:Although the cases that had a potentially good prognosis were little (4 cases), interceptive extraction of primary canines would mostly be beneficial for these patients as it will minimize the treatment time, cost and complications.

Determination of the position of impacted maxillary canine – A panoramic radiographic study

“…However, the British Orthodontic Society -Orthodontic Radiographs guidelines have reported that there is no indication for the routine use of CBCT to detect impacted maxillary canines as the CBCT technique is associated with a higher overall effective dose of ionizing radiation than the conventional radiography. 11 In the present study (Table 1), the female to male ratio was 2.57:1, which is in accordance with many studies which showed that these impactions are more common in females, compared to males, with a ratio of 2:1. 1,3 However, a study conducted by Pico et al found the number of male and female patients in a ratio of 1:1 and justified that by their reduced sample size (only 28 impacted canines in 20 patients).…”

Three-dimensional evaluation of maxillary sinus volume, skeletal and dentoalveolar maxillary anterior region, in unilateral palatally impacted maxillary canine (Cross-sectional study)

“…[ 12 ] The prevalence of maxillary canine impaction in (x) population was (6.78%), and in terms of the investigated sample's gender, the number of impacted canines was higher in females than in males and also reported that the impaction occurred more unilaterally than on both sides that agrees with our findings. [ 13 ] The intensity and direction (positive or negative) of a relationship between two variables can be summarized using Spearman's rank correlation coefficient. The answer will always be between 1.0 (a perfect positive correlation) and −1.0 (a perfect negative correlation).…”
