Abstract
AIM: To evaluate the radiographic technical quality of root fillings performed by undergraduate students at a dentistry faculty in Turkey. METHODOLOGY: A random sample of 2000 records of patients who received dental treatment at the Faculty of Dentistry, University of Gazi between 2000 and 2003 was investigated. The final sample consisted of 1,893 root-filled teeth with 3,692 root canals in 1,654 dental patients. For each root-filled tooth, at least three periapical radiographs were examined: preoperative, working length determination and postoperative. The length, density and taper of root fillings were recorded. The length of root fillings was recorded as adequate, short or overfilled. Density of root fillings was recorded as adequate or inadequate. Taper of root fillings was recorded as adequate or inadequate. Results were evaluated statistically using one-way analysis of variance (anova) and chi-square analysis. RESULTS: Sixty-nine per cent, 53.2% and 68.3% of root fillings had adequate length, density and taper, respectively; only 33% of teeth fulfilled these three criteria at the same time. The relationship between the length, density and taper of the root filling and the presence of canal curvature was statistically significant (P < 0.001). There was no significant difference between maxillary and mandibular teeth according to the adequacy of the root fillings. The highest percentage of adequate root fillings was found in maxillary canines (51.5%). CONCLUSIONS: The percentage of adequate root fillings performed by undergraduate students was only 33%.
