ABSTRACT
Objective:
To study the effect of different wetness degrees in the root canal on the canal sealing.Methods:
160 root canal prepared single rooted teeth were divided into 4 groups (n = 40) by the root canal wetness degree (water content, V) (1) 0. 250 ~0. 299, (2) 0. 300 ~ 0. 599, (3) 0. 600 ~ 0. 899 and (4) 0. 900 ~ 1. 199 respectively. 80 teeth were divided into 4 groups (n = 20) for dye leakage test and another 80 for bacterial microleakage test. Zinc oxide paste (ZOP) and AH-Plus (AH-P) with vertical condensation of warm gutta-percha were respectively used to seal the canals in each group of the samples (n = 10) . The length of in vitro tooth dye penetration was measured by stereomicroscope; the time (days) of turbidity in the bacterial leakage model observed and compared.Results:
Of all the canals sealed by ZOP or AH-P with the increase of the wetness the dye infiltration length increased significantly (P <0. 05) and the days in which the faecal intestine ball infiltrated into the lower chamber of the model was gradually decreased (P <0. 05) .Conclusion:
The increase of root canal moisture may reduce the sealing of the root canal.
