Estudio comparativo de la microfiltración apical de tres sistemas de obturación endodóntica: estudio in vitro

The purpose of this study was to compare the microleakage among three systems for sealing of root canals. Fifty five root canals of extracted human teeth were prepared using the K3® VTVT system. The specimens were divided in five groups and then they were filled (15 for AH Plus®, 15 for EndoRez®, 15...

Sumario:The purpose of this study was to compare the microleakage among three systems for sealing of root canals. Fifty five root canals of extracted human teeth were prepared using the K3® VTVT system. The specimens were divided in five groups and then they were filled (15 for AH Plus®, 15 for EndoRez®, 15 for GuttaFlow®, 5 positive controls and 5 negative controls). After 2 weeks, the time when all the materials were completely hard, all the specimens passed through a thermocycling process of 100 cycles, then the roots were covered with 2 layers of nail polish, except on the area around the apical foramen. Subsequently the specimens were immersed on a solution of 2% methylene blue during 7, 15 and 30 days. After each period the microleakage was measured. The percentages of penetration in 7 days were: EndoRez® 1.5 mm + 0.36, GuttaFlow® 1.24 mm + 0.24 and AH Plus® 2.08 mm + 0.37. In 15 days the results were: EndoRez® 2.34 mm + 0.29, GuttaFlow® 1.86 mm + 0.11 and AH Plus® 2.00 + 0.15. In 30 days the results were: EndoRez® 2.52 + 0.28, Gutta- Flow® 2.08 mm + 0.25 and AH Plus® 2.02 mm + 0.22. Significative statistical differences were founded only between AH Plus® and the GuttaFlow® in 7 days (p < 0.05). According to the results obtained in the present study, GuttaFlow® showed the lower microleakage in 7 and 15 days, while in 30 days AH Plus® showed a lower microleakage.
