Abstract:

This study compared the CBCT and RVG in the measurement of endodontically treated teeth. A total of 26 (10 mandibular molars, 6 maxillary molars, 5 mandibular premolars and 5 maxillary premolars) teeth were selected, and the presence of missed canal, periapical radiolucency, length of obturation and voids were observed by CBCT and RVG. The differences between the findings by CBCT and RVG were compared by Z two-sample proportion test and a value of p< 0.05 was considered statistically significant. The results showed that RVG did not detect any missed canals from 26 teeth, whereas CBCT recognized missed canals in 4 mandibular molars and one in a maxillary molar tooth. The presence of periapical radiolucency was observed in two mandibular molars by RVG where, where CBCT detected periapical radiolucency in 4 mandibular molars, one maxillary molar, and one maxillary premolar. Regarding the length of obturation, CBCT did not detect overextension in any tooth but was detected in two mandibular molars and two mandibular premolar teeth by RVG. However, RVG did not detect any void in obturation. In contrast, CBCT detected obturation voids in 9 mandibular molars, 5 maxillary molars, one mandibular premolar, and two maxillary premolar teeth. Statistically significant differences between the CBCT and RVG were found in all variables. Therefore, it can be concluded that CBCT is more dependable in detecting canal obturation voids, missed canals, obturation extension and periapical radiolucency than the RVG.

Keywords:
