“…In the present study, extreme care was taken in the selection of the tooth dimensions, their distribution within the experimental groups, and their standardized preparation, thus minimizing the effect of human tooth variation, as was recently discussed by Tanalp and others. 34 Artificial crowns could alter the distribution and transmission of stresses into a post-root complex, 35 masking the reinforcing effect of tested approaches. Therefore, in this study as well as in other studies, 25,29 no crown restorations were made for teeth to allow evaluation of these approaches.…”

“…To improve such properties of MTA, researchers have mixed it with different additives including propylene glycol (PG) and calcium chloride (CaCl 2) [8][9][10] . Although the immediate apexification can be provided by MTA, still there is a necessity of obturating the remaining canal space for sealing purposes and providing a reinforcement of the weak structure 11) .…”

The aims were to evaluate the effects of different additives on the adaptation of mineral trioxide aggregate (MTA) plugs before and after different backfilling techniques and analyze the interference of filling procedures on the fracture resistance of simulated immature teeth. The apical parts of 60 teeth were filled with MTA mixed with distilled water (DW), propylene glycol (PG) or calcium chloride (CaCl2) and backfilled with cold lateral condensation (CLC) or warm vertical compaction (WVC). The specimens were subjected to adaptation analysis and fracture testing. CaCl2 addition resulted in poor marginal adaptation, while PG addition significantly decreased the fracture values (p<0.05). WVC technique negatively affected the marginal adaptation of MTA-CaCl2 plugs and decreased the fracture values of teeth with MTA-PG plugs (p<0.05). Mixing MTA with DW can be recommended as apical plug when the remaining root canal space is going to be filled with either CLC or WVC techniques.

Aim:The aim of this study was to evaluate the efficiencies of different conventional solvents on the removal of root fillings performed with MTA Fillapex root canal sealer and gutta-percha. Material and Method: Forty-five maxillary central incisors human teeth were included. Sample lengths were adjusted to 16 mm and root canal preparations were performed with K3 instruments up to 30/.04 size. MTA Fillapex® root canal sealer and gutta percha were used to obturate the canals with cold lateral condensation technique. The teeth were stored for 1 week at 37 ºC in 100% relative humidity. Specimens were randomly assigned into three groups (n:15): G1: Resosolv, G2: Endosolv E and G3: Guttasolv. 35/.04 K3 instruments were used as the final retreatment instruments. Final irrigation was performed and root canals were dried. The teeth were split along their long axis and operating microscope at 10x magnification was used to evaluate the amount of remaining root filling material. Samples were then scored. SEM and EDS analysis were used to enhance the accuracy of evaluations. Data were subjected to statistical interpretation using Kruskal-Wallis test at a 95% confidence level (p<0.05). Results: There were no statistically significant differences among the three experimental groups in the apical, middle and coronal thirds of the root canals (p>0.05). Intra group comparisons showed that apical, middle and coronal thirds of each group showed no significant differences among themselves (p>0.05). Conclusion: Root fillings performed with MTA Fillapex® and gutta percha could be retreated with the solvents used in the study.
