Aims: The aim of the present study was to compare diagnostic assessments of anterior tooth and bone status in a randomised cohort of pre-orthodontic patients using panoramic and periapical radiographs.

Method: Four hundred and forty-four cases with matched periapical and panoramic radiographs were examined by three observers. Two were final-year postgraduate endodontic students and the other, a final-year Honours degree dental student. Multirater Kappa values were used to assess the reliability of the observers, with a value of 1 equating to complete agreement.

Results: With the exception of endodontic Class 1 and 2 palatal invaginations, reliability exceeded 0.95 for all three observers. An assessment of the graduate endodontic students revealed only a marginal increase in the kappa values. Statistical analysis (p < 0.05) determined that developmental anomalies or tooth/bone pathoses were more reliably detected by observers using periapical radiographs compared with panoramic films. This finding has relevance given the likelihood of anterior dental trauma among young children.

Conclusion: While there have been considerable improvements in the quality of dental panoramic radiography, the present study indicated that a reliable pre-orthodontic or post-trauma diagnostic assessment should include both panoramic and intra-oral radiographs.
