- Maxillary canine impaction is a frequently found dental anomaly. Orthodontics is important to know the possibility whether or not canine will experience impaction. Among the diagnostic procedures to predict the canine which is potential to experience impaction is a routine panoramic radiography examination of mixed teeth. Many previous methods were used to predict canine impaction. In this study, prediction was conducted based on sector measurement, angulations, antero-posterior position of canine root apex and vertical canine crown hight based on panoramic photo analysis in the patients of 9 – 12 years old. The purpose of this study was to find out the proportion of predicted maxillary canine impaction based on the four variables above, which factor that had the biggest proportion when measuring the four variables, and to find out whether or not there was different proportion of predicted maxillary canine impaction between boys and girls. This is an observational study with cross-sectional approach. The samples were 70 panoramic photographs consisting of 35 photographs belonged to the boy patients and 35 belonged to the girl patients of 9 – 12 years old respectively. Of the 70 samples, 21 samples (30%) were 9 years old, 27 (38.57%) were 10 years old, 14 (20%) were 11 years olds and 8 (11.42%) were 12 years old. cephalometric action was done twice (2 times) and then all of the data were recorded by means of SPSS program. The result of this study showed that most of the canine did not have potential impaction. 109 teeth (87.2%) were located at sector 1, and 16 teeth (12.8%) had potential for impaction. Based on sector measurement, it was found out that 16 teeth were predicted to have impaction which was spread at sector 2 and sector 4. The proportion based on the angulations, only 12 teeth (subjects) (9.6%) which were located at sector 2, and 4 teeth (subjects) (3.2%) were located at sector 4, meaning that there were 16 teeth (12.8%) which were predicted to have impaction based on angulations evaluation. The existence of different proportion of canines which were potential for impaction based on the measurement of antero-posterior position of canine root- apex showed that only 1 tooth (0.8%) which was predicted to have impaction while the position of vertical canine crown hight in proportion which was predicted to have impaction was 26.4%, meaning there were 33 teeth of 125 teeth (subjects) which were predicted to have impaction. Of the total evaluation, it was found out that the proportion of predicted canine impaction was 34.4% or 43 teeth experiencing impaction of 125 teeth (subjects), and there were 82 teeth (65.6%) of the predicted teeth proportion which did not experience impaction. In this study, it was found out that, of the four parameters measured, the position of vertical canine crow nhight in direction had the biggest proportion. Different proportion of canine impaction between the boys and the girls showed that the proportion of canine impaction of the girls was higher (17.6%) compared to that of the boys (16.8%).
