DETERMINATION OF WORKING LENGTH VARIATION IN MAXILLARY CANINE: AN ANALYTICAL STUDY
Accomplishment of a successful root canal treatment is the primary aim of any dental surgeon. There are variable reports that working length of maxillary canines has great impact on the treatment outcome. A descriptive study was conducted with the aim of measuring the average working length of maxillary canine in patients presenting to the Operative Dentistry Department of Rawal Institute of Health and Sciences, Islamabad. During the study the materials and equipment comprised of 5.25% sodium hypochloride, k file (mani), periapical radiograghs and an apex locator. The collected data was analyzed in SPSS software using descriptive statistics to measure mean and standard deviation for numerical variables and frequency and percentages for categorical variables. The sample size was comprised of 30 human maxillary canines, only one teeth was observed per patient. There were 16 males and 14 females. The average working length was 25.1 mm in this study. The results of this study showed that the average canine working length was larger in males than females, however, this difference was not statistically significant. After evaluation of present study findings it can be suggested that knowledge of different canine root lengths have an impact on the obturation methods and also on the accomplishment of successful root canal treatment procedures.
