Objective: To compare two cementing techniques in uniradicular teeth with root weakened walls.Methods: An in vitro experimental study was done with sixty collected teeth which were divided into three groups at random (A, B and C). The conventional technique with resin cement was done in 20 teeth with narrow canals 20 other teeth with weakened root walls (groups A and B). The technique of root reinforcement and flowable resin cement was used in the remaining 20 teeth (group C) which had weakened root walls. The dislodging force in the three groups was tested using an universal testing machine. The Mann Whitney and one-way ANOVA tests were used with a p value < 0.05 as statistically significant.Results: It was not found a statistically significant difference when comparing the dislodging force in the three groups (p = 0.064) but, it was found a difference when comparing traction forces (p = 0.005). In addition, it was observed that there was less adhesion between dentin - restorative interface materials in the three groups. The behavior exhibited between said post - cement poles showed higher adhesion with the resin cement.Conclusion: Group C showed greater resistance to the tensile force perhaps because the resistance of the tooth structure was increased when the root canal was reinforced with composite resine. The conventional technique was effective in the case of restoring teeth with narrow root canals. |
