Abstract

Aim: The study aimed to evaluate and compare Neoputty MTA and MTA Angelus as perforation repair material regarding marginal adaptation.
Materials and methods: Twenty extracted human permanent mandibular molar teeth were collected and cleaned with sodium hypochlorite. Specimens were amputated 3 mm below the furcation area by using a tapered with round diamond size #12 and wheel stone. The height of the crowns of all samples were adjusted to 8 mm. Endodontic access cavity was made in each specimen by using a high-speed tapered with round diamond stone size #12 with air-water coolant. Impressions were taken for each tooth using condensation silicon to provide negative replicas of the perforation. Intentional perforation in all samples was made between the mesial and distal orifices using tapered with round bur size #12. The teeth were randomly divided into two groups each containing 10 teeth. The perforations were sealed as follows: Group A with MTA Angelus and Group B with Neoputty MTA. The repair materials of both groups were evaluated for marginal adaptation using SEM. Data were statistically analyzed using two sample t-test.
Results: Quantitative SEM observations illustrated that the mean gap at the dentin–furcation repair material interface was as follows: MTA Angelus showed higher mean gap distance (6.90 ±2.24 µm) compared to Neoputty MTA (5.79 ±1.31 µm). Statistically there was no significant difference between MTA Angelus and Neoputty MTA concerning marginal adaptation.
Conclusion: Neoputty MTA could be used instead of MTA Angelus as perforation repair material.
