[Tooth decay complications incidence].

The aim of the article is to assess the quality of endodontic therapy and estimate further treatment needs. 900 orthopantomograms of 442 men and 458 women (aged 18-70) without any clinical manifestations of endodontic pathology were examined for endodontic treatment. 1,170 patients (41%) had additional intraoral radiographs taken for assessment of their periapical status. 2,852 (13.8%) of the 20,724 teeth examined had periapical lesions and/or root fillings. 2,503 of the 2,853 teeth were endodontically treated, only 1,011 of them (40.4%) having all their root canals obturated. 612 (41.3%) of the 1,492 (59.6%) teeth with inadequate root canal fillings hat a healthy apical periodontium. Of the 1,229 teeth to be endodontically treated 349 teeth required primary treatment, 880 required retreatment.
