Abstract

Aim. The aim of study was to assess the root-filled teeth with periapical lesions by using Periapical and Endodontic Status Scale (PEES) index. Materials and method. The study group included 166 filled root canals (70 molars and premolars) in 42 patients (gender: 12 males, 32 females; mean age 35.90 ± 10.571 yrs.) treated in Clinical Base of Faculty of Dental Medicine, U.M.F. “Grigore T.Popa” Iasi. The evaluation of root canals and periapical areas was performed by using the two components of Periapical and Endodontic Status Scale (PEES) index, COPI and ETTI. Results. Distribution of COPI components in the study group was as follows:  COPI D: 30,7% D1, 69,3% D3; COPI R: 27,1% R1, 70,5% R2, 2,4% R3; COPI S: S1 16,3%, S2 21,7%, S3 62%. Distribution of ETTI components in the study group was as follows: ETTI L: 42,2% L1, 43,4% L2, 5,4% L3, 5,4% L4, 3,6% L5; ETTI H: 36,7% H1, 63,3% H2; ETTI CS: 10,8% CS1, 89,2% CS2; ETTI CF: 3,6% CF1, 9% CF2, 5,4% CF3, 81,9% CF5. Conclusions. In endodontically treated teeth with apical periodontitis, PEES indices allowed to detect 62% of root canals with periapical lesions with diameter over 5 mm, while more than two thirds of teeth roots had periapical lesions extended in cortical bone (69,3%) affecting more than one root (70,2%). All teeth roots with apical radiolucency and non-treated root canals as well as roots with perforations or resorptions had apical lesions with diameter over 5 mm extended in cortical bone. The presence of apical radiolucency more than one root was associated to overfilling or root resorption.
