- Evidence-based Ranking: 5
- Purpose/ Objectives: To investigate the reliability of radiographic diagnosis
Methods and Materials: 253 cases selected at random. Six different evaluators looked at final and 6-month recall films and judged the treatment to be successful, failing, or questionable based on the absence, presence, and change in the periradicular area, and the preoperative pulpal diagnosis.
Results: 253 cases: 159 teeth were pulpless, and 94 were vital. The examiners agreed on less than half cases. (47%) When asked just to judge if there was a periapical lesion present, they still disagreed over half of the time. Even when asked for only 5 of 6 to agree, only 67% of the cases were in agreement. Overall, maxillary molars had the greatest percentage of disagreement, although all teeth had great percentages.
Authors Conclusion: No clear conclusions, except future studies should take these findings into account.
Reviewers Comments: The results show radiographic interpretation can be very subjective.
