The technical quality of nonsurgical root canal treatment performed by a selected cohort of Australian endodontists

Abstract

Aim: To investigate the technical quality of nonsurgical root canal treatment performed by endodontists in Melbourne, Australia. Methodology: Clinical and radiographic records of 100 sequential nonsurgical patients were obtained from each of six endodontists working in private practice. The following variables were analysed: proximity of root filling to radiographic apex; homogeneity and radiodensity of root filling; lateral adaptation of the root filling to the canal walls; taper; extrusion of material; small, appropriate or excessive apical enlargement; presence of lateral canals; transportation; procedural errors. The radiographs were assessed by three independent evaluators. Exploratory ..
