Body
Objectives: The aim of this study was to evaluate radiographically the periapical status and
technical standard of root canal treatments performed by undergraduate dental students after
2 years following the treatment.
Methods: A random sample of 264 patients who received root canal treatment by undergraduate
students at the Faculty of Dentistry in 2009 was recalled after 2 years. The study sample
consisted of 319 root-filled teeth in 158 dental patients who presented (female=97, male=61).
For each root-filled tooth, two periapical radiographs were examined to identify the periapical
status, one showing pretreatment and the other showing posttreatment status. The quality of
endodontic treatment was examined according to the distance between the end of root filling
and radiographic apex and the density of the obturation according to presence of voids.
Results: 54.2% of roots had fillings of acceptable length, while 37.3% were short and 7.8%
were overfilled and 0.6% were left unfilled. 2.5% teeth were observed with broken endodontic
instruments. After 2 years, PAI scores of teeth with acceptable length of root canal filling
(0-2 mm from the radiographic apex) were found take lower than those of the over filling and
short filling cases (>2mm) (p
