Aim:
The aim of this study is to assess the coronal marginal leakage of three temporary restorative materials used for root canal sealing after endodontic treatment.
Materials And Methods:
A total of 88 single-rooted teeth were submitted to biomechanical preparation and filled by lateral condensation technique. After obturation process, the teeth were randomly separated into four groups, being two teeth of each group used as positive and negative control. Temporary sealing was performed as follows: GI - Clip F (VOCO); GII - Bioplic (Biodinβmica); GIII - Vitremer (3M ESPE) and GIV - Ketak N100 (3M ESPE). Next, the specimens were immersed into Indian ink for 30 and 60- days, being 10 specimens for each time interval and then submitted to diaphanization to verify the amount of coronal leakage using a measuring microscope.
Results:
Leakage mean values within the 30-day period were as follows: Vitremer (0.3 mm), Ketak N100 and Clip F (0.6 mm) and Bioplic (1.7 mm). Within the 60-day period, leakage means were 1.1 mm, 1.5 mm, 2.2 mm and 2.6 mm, respectively.
Conclusions:
None of the materials was capable of preventing marginal leakage within the 30- and 60-day period. In both time intervals, Bioplic presented the highest mean of leakage and Vitremer the lowest.
