Prevalence and patterns of impacted maxillary canine in a Peshawar sample

Maxillary canines are important aesthetically and functionally, but impacted canines are more difficult and time consuming to treat. Permanent maxillary canine impaction has been reported in about 1% to 5% of the population. The objective of this study was to determine the prevalence of impacted maxillary canine in patients visiting to Khyber college of dentistry, Peshawar. A total of 500 patients of 15 years and above were examined clinically. Those having maxillary canine impaction were advised Anterior Occlusal View and panoramic radiograph to determine the patterns of impaction by vertical parallaxing technique. Data were processed in SPSS version 16.0. The chi-squared test was used to reveal any differences in the distribution of impacted maxillary canines when stratified by gender and location [left or right]. A p-value of <0.05 was accepted as statistically significant. Out of 500 patients examined 20[4%] had maxillary canine impaction. The mean age was 19.05 +/- 3.15 years. Age was ranged from 15 to 25 years. Female to male ratio was1.85:1. Females had more impaction of maxillary canine than males[p=0.000]. Palatal were the most common in males while buccal were in females. Left side was commonly involved in impaction in both genders

relation of vertical facial pattern with sagittal craniofacial dimensions: a study

The aims of this study were to assess the relation of sagittal and vertical facial dimensions in lateral cephalometric analysis and occurrence of hyperdivergeney in various facial profiles. This study was conducted on 200 patients in the Department of Orthodontics Khyber College of Dentistry Sagittal analysis was done by measuring ANB angle, and vertical relation was determined by MMA angle and Lower Face height ratio. Ninety eight patients were skeletal class I [49%] followed by 92 patients [46%] in skeletal class II. Forty eight percent patients were normodivergent followed by 37% hyper divergens facial profile. Fifty one patients [52.04%] of skeletal class I patients were normo divergent and 43 patients [46.73%] of skeletal class II patients were hyperdivergent. Most of normodivergent patients were skeletal class I and hyperdivergent were class II
