Abstract

The aim of study was to assess the periapical area and the distribution of CBCT-PAI indices in root-filled teeth with chronic periapical lesions. Materials and method. The cross-sectional study included 78 patients (gender: 24 males, 54 females; mean age 49.13 ± 14.596 yrs.) with 181 root-filled teeth diagnosed with apical periodontitis (AP) (mean follow-up of 5.49 ± 1.831 yrs.). Patients were selected from those treated in a private dental clinic. Clinical examination and CBCT assessment of the root and its periapical area were performed to evaluate the severity of apical periodontitis by PAI-CBCT scores. CBCT images were obtained using PaX-Uni3D (TVAPANO04, VATECH). The periapical lesions diameter was measured in coronal-apical, mesial-distal and buccal-oral sections using the Ez3D 2009 Plus software application. CBCT parameters were set for 20 second exposure time, 85 kV, 5mA. CBCT-PAI scores were assessed by statistical analysis within study group in relation to various parameters (sociodemographic, local factors, type and quality of coronal restoration and root-canal fillings). Failure of endodontic treatment was defined by CBCT-PAI scores 3-5. Results. The distribution of CBCT-PAI indices was as follows: 50,8% of teeth with CBCT-PAI 1-2, 19,3% of teeth with CBCT-PAI 3; 29,9% of teeth with CBCT-PAI 4-5. Failure of endodontic treatment (CBCT-PAI 3-5) was detected in 49,2% of the root-filled teeth.  Highly significant statistical differences were found in the distribution of CBCT-PAI indices related to age groups, follow-up, dental-group, quality of coronal restoration, quality of endodontic treatment.  Conclusions. CBCT-PAI scores 3-5 were detected in 49,2% of the root-filled teeth with sign of chronic periapical lesions. Highly significant statistical differences were found in the distribution of CBCT-PAI 3-5 indices related to age groups, follow-up, dental group, quality of coronal restoration and endodontic treatment. The use of CBCT-PAI scores allow accurate, reliable and reproducible evaluation of the success and failure of the endodontic treatment.
