Abstract
BACKGROUND: Mineral Trioxide Aggregate (MTA) is widely used in endodontics due to its biocompatibility and sealing properties. The gel form of MTA has been introduced to enhance handling and adaptation characteristics. OBJECTIVE: This study aims to compare the sealing ability and adaptation of the gel form of MTA to dentinal walls using an in-vitro model. MATERIALS AND METHODS: The study involved 25 extracted human premolar teeth, divided into three groups: MTA gel form, conventional MTA, and control (no MTA). Sealing ability was assessed through dye penetration analysis, and adaptation was evaluated using scanning electron microscopy (SEM). RESULTS: The gel form of MTA exhibited superior sealing ability and adaptation compared to conventional MTA and control groups. Statistical analysis (ANOVA, P < 0.05) confirmed significant differences between the groups. CONCLUSION: MTA in gel form demonstrated improved sealing ability and adaptation to dentinal walls, suggesting its potential as an effective endodontic material.
