Abstract
AIM: To determine the prevalence of apical periodontitis and the quality of root fillings in an adult Irish population using a retrospective analysis of orthopantomograms (OPGs). METHODOLOGY: A systematic sample of clinical records and OPGs of 302 adult patients attending the Dublin Dental Hospital, Ireland, were screened by two examiners to determine the quality of root canal treatment and the prevalence of apical periodontitis. The operators who carried out the treatment were unknown. Two examiners inspected OPGs after inter-examiner correlation. European Society of Endodontology (ESE) guidelines were used to determine adequacy of root treatment. RESULTS: Of the 7427 teeth examined 2% had root fillings. Apical periodontitis was evident in 1.6% of all nonroot filled teeth whilst 33.1% of the subjects had at least one tooth with apical periodontitis. Of the root filled teeth, 25% had apical periodontitis and 52.6% were considered technically inadequate by ESE guidelines. There was a statistically significant (P < 0.05) negative correlation between the quality of the root fillings and the prevalence of apical periodontitis. Posterior root filled teeth (premolars and molars) had a greater prevalence of apical periodontitis than anterior root filled teeth. CONCLUSIONS: The technical quality of root fillings in an adult Irish population was poor and was consistent with a high prevalence of apical periodontitis.
