Abstract
Introduction: Bioceramic materials have a come long way in terms of their potential role in critical tooth saving procedures, especially during endodontic management. The process of developing new materials with MTA like properties is still in progress in order to make materials which are clinically efficient but at the same time cost effective. One of the essential pre-requisites of these bioceramic materials is their ability to attain a highly alkaline pH after setting so that they can exhibit the osteogenic potential. The current study was carried out in these lines in order to evaluate the alkalinity of the newly introduced MTA in the Indian market in order to explore its osteogenic potential as the biological properties of MTA are attributed to its alkalinity.
Aim: To investigate the pH of a novel Bioceramic material, MTA (Maarc Dental, India) in order to validate its osteogenic potential.
Methodology: MTA Powder was mixed with its special liquid as per the manufacturer’s instructions, ensuring the complete dissolution of the powder particles. 20 polyethylene tubes measuring 3 mm in diameter and 2 mm in height were filled with freshly prepared material. The samples were sealed in tubes containing 10 ml of distilled water and stored at 37 degree celsius. The pH was measured after 3 hours, 24 hours and 48 hours using a calibrated pH meter.
Observations and Results: The maximum pH was observed to be 10.59 after 24 hours with a mean of 10.52. After 24 hours, a gradual fall in pH was observed in the samples.
Conclusion: Within the parameters set in this study, it was concluded that new MTA seems to be promising enough as it obtained a high alkaline pH after 24 hours of mixing. However, long term clinical evaluation in patients is required to support the laboratory findings.
