Maxillary canine impactions are the second most common impactions following mandibular third molar impaction . There is always a confusion for the the clinician regarding the management of canine impactions, hence they need to be familiar with the differences in the surgical management of the labially and palatally impacted canines, the best method of attachment to the canine for orthodontic force application, the advantages of one-arch versus two-arch treatment, and the implications of canine extraction. The following review focusses on the various factors that influence all these decisions .

Objectives: To determine any possible association between sella turcica bridging and canine impaction.
Subjects and methods: Orthodontic records consisting of standard-quality lateral cephalograms and dental panoramic radiographs were selected. Thirty patients with impacted canines (19 females,11 females; mean age, 16.0 ± 22.3 years) and 30 controls with erupted canines (15 males, 15 females; mean age, 15.1 ± 24.1 years) were included in the study. Sella dimensions between the patients and the controls were compared by using Independent sample t test whereas the relation of sella bridging with impacted canines was analyzed using the chi-square test.
Results: In the results, significant statistical difference was found to be present among male subjects and female subjects in relation to mean sagittal interclinoid distance (p<0.05). On comparison of degree of calcification (Leonardi classification) in cases and control, occurrence of type I sella bridging was found to be 3 (10%) and 19 (86.4 %) in subjects (n=30) and control (n=30) respectively, type II sella bridging was observed in 21 (70%) subjects and 11 (34.4%) control respectively, type III sella bridging was observed in 6 (20%) subjects. Degree of calcification in cases with stratification in regards to gender 
was studied using Leonardi ordinal scale classification. Occurrence of type I sella bridging was found to be 3 (27.3%) and 0 (0%) among male subjects and female subjects, type II sella bridging was seen in 6 (54.5 %) male cases and 15 (78.9 %) female cases and type III sella bridging was seen in 2 (18.2 %) male cases and 4 (21.1%) female cases respectively.
Conclusions: The frequency of sella turcica bridging was increased in patients with canine impactions whereas sella turcica length, depth and diameter were reduced in patients with canine impactions. Sella length was increased in males than females in the impacted canines group. The chances of having partial or complete bridging in subjects with impacted canines were approximately 4 times greater than those with erupted canines.

The aim of the study was to determine the prevalence of maxillary canine impaction in Class II Division 1 malocclusion. Impacted teeth are defined as teeth that remain incompletely or completely embedded in the jaw bone or mucosa. The maxillary canine is one of the most important teeth in terms of aesthetic and function. The maxillary canine impaction is more frequent then mandibular canine impaction. After the third molars the maxillary canine are the second most frequently Impacted teeth.This retrospective study was conducted in a university setting. Data was collected from the patients who visited Saveetha Dental College between June 2019 and March 2020. Among 980 patients who had reported for orthodontic treatment and prevalence of maxillary impaction was calculated. From this data 100 case records of class 1 and 100 case records of class 2 malocclusion cases were selected randomly and variables like age, gender, and frequency of maxillary canine impaction were recorded. The prevalence of maxillary canine impaction was 2.4% according to this study. Gender distribution was 41.6%males and 58.4% females. The results of this study showed that Maxillary canine impaction was more prevalent in females when compared to males ( 6.6% : 5.2%). Maxillary canine impaction was higher in class I malocclusion when compared to class II division I (8% : 4%) and with higher prevalence in females with Class I malocclusion.However prevalence of canine impaction was not significantly associated with gender and type of malocclusion
