A comparison of the quality of root canal treatment in two Danish subpopulations examined 1974-75 and 1997-98

Aim The aim of this study was to compare the quality of root canal treatment in two Danish subpopulations. Methodology Group 1 (358 patients) was examined 1974–75 and group 2 (244 patients) 1997–98. All patients were more than 20 years old. All had undergone a full‐mouth radiographic survey. In root...

Summary:Aim The aim of this study was to compare the quality of root canal treatment in two Danish subpopulations. Methodology Group 1 (358 patients) was examined 1974–75 and group 2 (244 patients) 1997–98. All patients were more than 20 years old. All had undergone a full‐mouth radiographic survey. In root‐filled teeth the following parameters were assessed: the quality of the coronal restoration or crown, the lateral seal of the root filling, the length of the root filling, and the periapical status. Chi‐squared tests were used for the evaluation of differences between the groups. Results In group 1 there were 975 endodontically treated teeth, in group 2 there were 753. In group 1 the majority of root‐filled teeth were premolars, in group 2 the majority were molars (P
