Objective:
The aim of this study was to compare the periapical status of different teeth by using the Periapical (Pa) and the cone beam computed tomography (CBCT) radiographs.
Patients And Methods:
Pa and CBCT radiographs were obtained from the patients who required Endodontic treatment. The absence and presence of periapical lesions were investigated using both Pa and CBCT radiographs. Periodontal conditions other than periapical lesions were also observed by using both radiographs and recorded. Cohen's Kappa analysis was performed to observe the inter-rater and intra-rater reliability. Descriptive statistics including frequency and percentages of presence and absence of periapical lesions were analyzed. Independent t-test was conducted to compare the Pa and CBCT for the detection of periapical lesions. Chi-square test was used to investigate the distribution of gender and periapical lesions by both radiographs.
Results:
A total of 204 teeth from 72 patients (29 female and 43 male) were assessed via CBCT and Pa radiographs. Inter-observer and intra-observer reliability showed the absolute level of agreement. T-test showed there is significant difference between Pa and CBCT radiographs regarding detecting periapical lesions. Chi-square test showed no significant differences between the gender and apical pathosis.
Conclusions:
CBCT is more reliable to detect periapical lesions compared to the Pa radiographs.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
