Objective: The aim of this study was to use cone beam computed tomography scans from a database to assess the prevalence of periapical radiolucency found in root canal treated teeth. Additionally, evaluate the quality of coronal restoration and root canal treatment, as well as their impact on the periapical tissue.

Material and Method: 301 root canal treated teeth were randomly selected and examined from 143 cone beam computed tomographic scans, and teeth were categorized as healthy or diseased based on the periapical status. Other variables such as tooth type, endodontic treatment quality, presence of fixed coronal restorations and posts, type and quality of coronal restorations were investigated for their relationship with periapical status. The chi-square test is a statistical method for determining the relationship between sets of data.

Results: The overall prevalence of periapical radiolucency was (64.1%), whereas the maxillary molars and mandibular molars were more affected than other teeth types (75.7%), (65.9%), respectively. The length and homogeneity of the root canal filling were significantly associated with periapical status. While the teeth had both inadequate root canal treatment and coronal restoration be revealed with diseased periapical status were (91.8%).

Conclusion: This study shows that the prevalence of periapical radiolucency is relatively high. Molar teeth were most likely to be associated with periapical radiolucency. Poor homogeneity of root canal filing was the most frequent type of technical error associated with periapical radiolucency. Moreover, the results showed that inadequate root canal filling and coronal restoration were associated with an increased incidence of periapical radiolucency.
