Intended Use

Bright MTA Sealer Plus is used for filling root canals

Device Story

Bright MTA Sealer Plus is a ready-to-use, injectable, calcium silicate-based paste for root canal filling. The material is delivered via a pre-loaded syringe into the root canal space, where it hardens and obturates the canal. It is intended for use by dental professionals in a clinical setting. The device provides a biocompatible seal for root canals, including applications for root-end filling and repair of root resorption. Its low film thickness facilitates penetration into lateral and accessory canals, potentially improving the quality of the root canal obturation and long-term clinical outcomes for the patient.

Clinical Evidence

Bench testing only. No clinical data provided. Performance was validated against EN ISO 6876:2012 standards for flow (27mm), setting time (≤360 min), film thickness (30 μm), radio-opacity (4.6mm), and solubility (0.2%). Biocompatibility was confirmed via ISO 10993 testing, including cytotoxicity, irritation, sensitization, systemic toxicity, genotoxicity, implantation, and carcinogenicity assays.

Technological Characteristics

Calcium silicate-based injectable paste. Composition: CaCO3, Al2O3, SiO2, NaHCO3, ZrO2, Li2CO3, 1,3-Propandiol, Polyethylene glycol, and polar acidic ester of long chain alcohols. Form factor: Pre-loaded syringe. Non-sterile. Shelf-life: 2 years. Permanent contact duration (>30 days).

Indications for Use

Indicated for filling root canals in human teeth.

Regulatory Classification

Identification
