BACKGROUND AND OBJECTIVE: Producing a new sealer using local technology helps to produce dental materials with ideal properties in the country and at a lower cost. The present study was performed to investigate the physical properties of a calcium silicate- and hydroxyapatite-based endodontic sealer in three different mass compositions.
METHODS: In this laboratory study, a new sealer was made in Mashhad Dentistry School. Three different weight ratios in the experimental groups S1= Cs Si Sr, S2= Cs Si2 Sr and S3= Cs Si Sr2 were evaluated in terms of setting time, working time, film thickness, solubility, and flow. Experiments were performed according to ISO/FDIS6876:2012 standard. To determine the crystal structure of the sealer in three different formulas, the samples were examined by X-ray and Energy-dispersive X-ray Spectroscopy.
FINDINGS: The highest amount of flow was related to S1 (17.08 mm) and the lowest amount was related to S2 (16.2 mm). The lowest solubility was related to the formula S1 (1.83%) and the highest was related to S2 (3.6%). Experiments also showed that the amount of film thickness in the formula S2 and S1 have the highest and lowest levels, respectively. Setting time in the samples was 330 minutes in S1, 428.33 minutes in S3 and 1030 minutes in S2. S1 had the longest working time, followed by S3 and S2, respectively.
CONCLUSION: Based on the results of this study, sealers S1 and S3 showed good results in accordance with the standards in setting time, working time, film thickness, solubility, and flow tests, but sealer S2 showed results close to the standard.
Keywords: Sealer, Hydroxyapatite, Root Canal Treatment.
