Title : A Comparative study to evaluate marginal adaptation of Bioceramic, MTA in vital pulpotomy on primary teeth (an in vitro study)
Author(s) : Rama Awad, Abdul Wahab Nourallah
Abstract :
Aim: The main goal of this study was to compare the microleakage of MTA and Bioceramic, using Scanning Electron
Microscopy in pulpotomized primary molars.
Materials and Methods: Study design: 10 extracted primary molars (caries-free or not) were used and randomally
distributed among two groups of study (n=5). Pulpotomy was conducted using either MTA or Bioceramic, the teeth
were then restored with composite resin. The crowns were resected longitudinally (bucco-lingual direction) into two
halfes. The teeth were thermocycled to 200 rounds between 5° and 55°C in distilled water, with 30s dwell time in
each bath, The samples were mounted on an aluminum stub and marginal gaps were examined and recorded in
micrometer using Scanning Electric Microscopy (SEM)
Results: Variable gaps were observed between the materials and dentinal walls. MTA had the largest mean gaps
(mean 6.716), whereas BC had the smallest mean gaps (1.428).
Statistic: The study results were analysed using an independent sample t-test.
Conclusion: This study showed that Bioceramic was comparable to MTA in marginal adaptation. there has been a
superior behavior of Bioceramic than white MTA and it adapts better with the adjacent dentin. It is worth saying that
this study differs from other studies measured the marginal adaptation with dentin by using SEM on filled primary
teeth.
