Notes
- AIM: To test the hypothesis that an increased utilization of nickel-titanium rotary instrumentation (NTRI) by general dental practitioners will lead to an increased frequency of good quality root fillings. A second aim was to determine whether the educational format would exert influence on the quality. METHODOLOGY: Dentists were assigned at random to three intervention groups: a 4-h lecture (L-group, n = 40); a 4-h lecture plus a full day hands-on course (LH-group, n = 40); or a control group receiving no instruction (n = 68). The control group received education later on in the study. Radiographs of two root filled molar teeth per dentist were selected at random before the start of the education program and after a 6-month clinical learning period. Using length, seal and shape of root-fillings a 5-level variable was created. RESULTS: The rate of good quality root fillings increased after the introduction of NTRI. Calculated over all types of roots the frequency of excellent (score 1) root fillings increased from 31% to 51% (P = 0.006) in the L-group and from 27% to 47% (P = 0.016) in the LH-group. The frequency of low quality root-fillings (score 5) dropped in the L-group from 22% to 16% (P = 0.29) and in the LH-group from 13% to 9% (P = 0.48). No statistically significant difference was seen among the controls. CONCLUSIONS: When NTRI technology replaced manual stainless steel techniques the rate of good quality root fillings increased. A significant drop in the rate of low quality root fillings was not found.
