Abstract
The purpose of retrospective study was to radiographically evaluate the apical sealing efficacy of cold-burnished gutta-percha as a root-end filling material. Radiographs of 41 teeth from 37 patients were used, with the recall period ranging from a minimun of 1 yr to amaximum of 6.7 yr. Radiographic findings were classified into one of three groups: 1. complete healing; 2, incomplete healing( scar tissue ); 3, unsatisfactory healing.
The results were as follows:
1. There was no significant difference in frequency of operation between male and female.
2. The teeth most frequently operated on were the maxillary central incisors ( 39% ). The Maxillary lateral incisors were the second largest group in frequency at 34%.
3. Patients between 21 and 40 yr of age formed the single largest group.
4. Complete healing was found in 58.5% of the recall cases, while incomplete and unsatisfactory healing occurred in 34.2% and 7.3% of the cases, respectively.
Based on this retrospective study, We concluded that 38 of 41 cases( 92.7% ) were considered to be successful and 3 cases ( 7.3% ) were determined to be failures.
