Abstract
Aim To determine the prevalence of apical periodontitis
and assess the quality of endodontic fillings in the population
of the city of Zagreb, Croatia.
Methods A total of 1462 orthopantomograms from new
patients at 6 different dental practices was analyzed during
2006 and 2007. The presence of periapical lesions was
determined by using the periapical index score (PAI). The
quality of endodontic fillings was assessed according to
the filling length and homogeinicity. Data were analyzed
using t test and ANOVA with Scheffe post-hoc test.
Results There were 75.9% of participants with endodontically
treated teeth and 8.5% of all teeth were endodontically
treated. Only 34.2% of endodontically treated roots
had adequate root canal filling length, while 36.2% of root
canal fillings had homogenous appearance. From the total
number of teeth with intracanal post, 17.5% had no visible
root canal filling. Using PAI 3 as a threshold value for apical
periodontitis, periapical lesions were detected in 8.5%
of teeth. Adequate quality of root canal fillings was associated
with a lower prevalence of periapical lesions.
Conclusion We found a large proportion of endodontically
treated teeth with apical periodontitis and a correlation
between the quality of endodontic filling and the
prevalence of periapical lesions. This all suggests that it is
necessary to improve the quality of endodontic treatment
in order to reduce the incidence and prevalence of apical
periodontitis.
