Aim To compare digital images of conventional radiographs with the original radiographs for perceived clarity of periapical lesions and the quality of root canal treatment. Materials and Methods One hundred and four intraoral periapical radiographs of patients with endodontically treated teeth were randomly selected. The radiographs were digitized using an MD300 USB X-ray Reader. The digital images were transferred to an HP laptop. Three evaluators compared each conventional radiograph with the matching digital image. The images were ranked for clarity and assessed for diagnostic quality; data were analyzed using the Reliability Calculation “ReCal.” Results. Both the digital images and conventional films had comparable clarity and diagnostic quality. Results indicated a moderate agreement between the evaluators. Conclusions Conventional radiographs digitized using an MD300 USB X-ray Reader have similar clarity and diagnostic quality in comparison to the original radiographs.

Due to their destructive impact on the tooth structure and the supporting periapical tissues, endodonticperiodontal lesions provide a significant challenge for the dentist in their care (i.e., bone and periodontal membrane). A thorough history is crucial to identifying the root of the problem and accurately diagnosing the patient's condition. This is a cross-sectional study conducted among 500 dentists in Riyadh using an online survey using convenient sampling. An online questionnaire was used consisting of questions related to demographic data followed by questions including knowledge, attitude, and confidence toward handling perio-endo lesions in clinics. 66% of the participants preferred referring EPL patients to specialists. 71% reported that using intra-canal medications can be useful in treating EPL. 58% revealed they did not have adequate knowledge regarding the successful management of EPL patients. The attitude of dental practitioners toward the treatment of Endo-Perio lesions is positive. But it does not correlate with their knowledge and practice.
