title: Difference in the periapical status of endodontically treated teeth between the samples of Croatian and Austrian adult patients.
abstract: Aim. To compare the periapical status of endodontically treated teeth between Austrian and Croatian adult patients and determine its relation to age, sex, position of teeth, and length of root canal filling. Methods. The study was conducted from 2007 to 2009 at two university dental clinics and included 163 Croatian (412 teeth) and 101 Austrian (430 teeth) patients. We assessed the periapical status of endodontically treated teeth by using the periapical index system and determined its relation to age, sex, position of teeth, and length of root canal filling. Results. Austrian patients had a greater number of diseased endodontically treated teeth than Croatian patients (P=0.001). In the age group 31-40 years, Austrian patients had apical periodontitis significantly more often (22.1% vs 12.2%, P<0.001) than Croatian patients. In relation to sex and position of teeth, no significant difference was found between the two groups. In Croatian patients, apical periodontitis was significantly more often present in molar than premolar (46.2% vs 29.7%, P=0.022) and front teeth (46.2% vs 24.1%, P<0.001). In Austrian patients, apical periodontitis was significantly more often present in molar and premolar than front teeth (molar-front teeth: 38.2% vs 25.5%, P=0.011; premolar-front teeth: 36.3% vs 25.5%, P=0.029). Croatian and Austrian patients with AP significantly differed in the number of adequately filled and underfilled teeth (both P<0.001). Conclusion. Apical periodontitis was significantly more present in endodontically treated teeth in Austrian patients. The difference in the periapical status between Croatian and Austrian patients was most related to age and length of root canal filling.
