Introduction: The purpose of this study is to evaluate changes in the endodontic treatment protocol of the CTM and determine which obturation- and luting agent application technique brings about the best adaptation of obturation material to the root canal dentine. The research question is “What is the adaptation of endodontic obturation material using different obturation- and luting agent application techniques: Cold lateral condensation and single�cone technique as obturation and gutta-percha cone and Lentulo spiral as luting agent application? Material and Methods: 334 obturated root canals were selected (data 2010-2017). The following groups were used: ‘group 1’: cold lateral condensation + gutta-percha cone(n=183), ‘group 2’: single-cone technique + gutta-percha cone(n=60), ‘group 3’: single-cone technique + Lentulo spiral(n=91). The adaptation was assessed visually using buccolingual x-rays and deemed acceptable or unacceptable. Results: In 65% of the cases, cold lateral condensation showed acceptable adaptation, compared to 78% using the single-cone technique. This difference was statistically significant. In 68,3% of the cases, gutta-percha cone as luting agent applicator showed acceptable adaptation. Using the Lentulo spiral as a luting agent applicator, the result was 76,9% of acceptable adaptation. This was not statistically significant. There were no significant differences between the combinations of obturation- and luting agent application techniques, and for the combination single-cone and gutta-percha cone, 78% led to acceptable adaptation, for single-cone and Lentulo spiral, this was 76,9% and for cold lateral condensation + gutta-percha cone this was 65%. Conclusion: This research shows that changes in obturation technique at the CTM contributed to the adaptation of obturation material of the root canal surface. Usage of the single-cone technique leads to better adaptation to the root canal surface than the cold lateral condensation technique. Luting agent application techniques and combinations of these with obturation techniques were not of significant influence on adaptation. This research shows that introduction of the Lentulo spiral in the endodontic treatment protocol at the CTM did not significantly contribute to better adaptation. Usage of the Lentulo spiral can be discussed, because in the literature other positive effects of it were described. These were not evaluated in this study. Also, single-cone and gutta-percha cone or single-cone and Lentulo spiral do not show significantly better adaptation than cold lateral condensation and gutta-percha cone, this could be caused by the size differences between groups. It was noticed that literature showed many different research methods to compare obturation- and luting agent application techniques, that is why results are not relatable to each other. To determine which combination of the techniques is superior to the others, it is advised to formulate and test a standardized research method.
