Abstract
Introduction: This cross-sectional study determined
the prevalence of apical periodontitis in 1086 root
canal–treated teeth from an urban Colombian population and evaluated the association of several factors
with the periradicular status. Methods: Periapical
radiographs were used for analyses, and teeth were
classified as healthy or diseased according to the periradicular status. Other factors were also evaluated for
their association with the periradicular conditions,
including gender, quality of both endodontic treatment
and coronal restoration, apical level of filling, and presence of post restoration. Results: Fifty-one percent of
the treated teeth were classified as healthy. Only 33%
of the teeth had endodontic treatment rated as
adequate. The quality of both endodontic treatment
and coronal restoration significantly influenced the periradicular conditions (P < .001). Combined data revealed
that teeth with both adequate endodontic treatment
and adequate restorations showed significantly better
periradicular status than the other combinations
(P < .01), except for teeth with adequate treatment
and inadequate restoration (P = .08). Canals filled up
to 0–2 mm short of the apex had a significantly higher
number of teeth rated as healthy than overfilled or
underfilled cases (P = .02). Regression analysis showed
that the quality of endodontic treatment was the most
significant factor influencing the periradicular status
(P < .001). Gender and presence of post restoration
had no association with the periradicular conditions.
Conclusions: Data from this Colombian population
showed a relatively high prevalence of apical periodontitis in root canal–treated teeth. This was largely due to
an equally high prevalence of treatments performed
under substandard technical quality. The quality of the
endodontic treatment was the most determinant
factor for healthy periradicular status. (J Endod
