Introduction. Estimation of frequency and quality of root canal fillings is
the way to evaluate endodontic treatment needs and success/failure rates of
performed endodontic procedures. Objective. The aim of this study was to
determine the frequency and quality of root canal fillings and the frequency
of apical periodontitis on endodontically treated teeth in a group of adult
patients from Serbia. Methods. In order to analyze the presence and quality
of root canal fillings and the frequency of periapical radiolucencies on
endodontically treated teeth, 3526 teeth were examined on orthopantomograms
of 153 adult patients. Results. Overall, 12.5% of examined teeth were root
filled, and 51.8% of them had radiographic signs of apical periodontitis.
The analysis of root fillings quality revealed the presence of more
inadequate ones (55.9%). The frequency of apical periodontitis was
significantly higher in teeth with inadequate than in those having adequate
root canal obturation (72.2% and 25.9%, respectively). Conclusion. The
frequency of apical periodontitis on root-filled teeth in this group of
patients was high, indicating a low success rate of performed endodotic
procedures and high endodontic retreatment needs.
