Comparison of vertical forces generated during root canal filling

Aim: The aim of this study was to examine vertical forces exerted during root canal obturation with three techniques, cold lateral condensation, ProTaper thermoplasticized and ProTaper Single- cone technique. Also to evaluate vertical forces exerted during root canal obturation with the cold lateral condensation technique performed by undergraduate students, dentists on specialty training in endodontology and specialists of endodontology. Methodology: Fourty-five single- rooted permanent teeth were used for the first part of the study. All specimens were instrumented using the ProTaper technique to F2 instrument and were randomly divided into three experimental groups (n=15 per group), obturated using the cold lateral condensation technique, ProTaper thermo- plasticized and ProTaper Single-cone technique. Ten single-rooted permanent teeth were used for the second part of the study. All specimens were instrumented using the step-back technique to master apical file size #25. Three groups of operators: 1) undergraduate students (n=10) ; 2) dentists on specialty training in endodontology (n=10) and 3) specialists of endodontology (n=10) obturated the root canals using the cold lateral condensation technique. Vertical forces were measured using the force measurement device, developed for simulation of endodontic treatment. Results: When cold lateral condensation obturation technique was used, vertical force of 1.21±0.24 kg was measured which was statistically significantly different in comparison to other techniques (p=0.0001). Vertical force recorded during root canal obturation by undergraduate students was 1.54±0.47 kg, 1.65±0.46 kg by dentists on specialty training in endodontology and 1.32±0.41 kg by specialists of endodontology. The results showed no statistically significant difference (p>0.05) between three groups of operators. Conclusions: The cold lateral condensation technique exerted higher vertical forces in comparison to the ProTaper thermo-plasticized and ProTaper Single-cone technique. There was no difference between vertical forces exerted by undergraduate students, dentists on specialty training in endodontology and specialists of endodontology during root canal obturation using cold lateral condensation technique.
