ASSESSMENT OF ROOT CANAL MORPHOLOGY IN UPPER SECOND PREMOLAR
Objective was to evaluate the root canal morphology for maxillary second premolar using two periapical radiographs.
This cross sectional descriptive study was conducted on 80 teeth at Rawal dental college, Islamabad. The inclusion criteria were both genders, age range 20 to 60 years, having irreversible pulpitis, pulp necrosis, and periapical pathosis in upper second premolars. The cases allergic to local anesthesia, upper second premolars with prognosis, fracture and internal resorption were excluded from study. Two periapical radiographs were used to determine the number and configuration of canals. Chisquare test was applied for comparison of canal morphology among genders and age groups.
The males were 44(55%) and females were 36(45%). The mean age was 34.93±9.03 years. The most common type of canal configuration was type II (n=31, 38.75%) followed by type IV (n=27, 33.75%). In 44(55%) participants there was single canal, in 35(43.75%) were two canals and in 1(1.25%) were three canals. Type II canal was more in males (n=25, 56.82%) than females (n=6, 16.67%). Type I canal configuration was more in females (n=9, 25%) than males (n=4, 9.09%). These differences were statistically significant (P=0.003).
For maxillary second premolars in upto half cases in our population have two canals and common types of canal configuration are type II and IV.
