Abstract

Background: This study aimed to assess the effects of Calcium hydroxide, Dentine/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">BioDentine, calcium-enriched mixture (CEM) cement, and Mineral trioxide aggregate (MTA) on root Dentin Flexural strength after a 30-day exposure period. Methods: This in vitro experimental study evaluated 25 freshly extracted sound human incisors with no caries or restorations. The apical 5 mm and the coronal two-thirds of the crowns were cut such that all samples had 10 mm length. Dentin samples (n=20 in each group) were then exposed to 2 mm thickness of Calcium hydroxide, Dentine/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">BioDentine, CEM cement, MTA, or saline (control) in petri dishes for 30 days. Finally, Dentin samples were subjected to a three-point bending test after the intervention, and the Flexural strength data were analyzed using one-way ANOVA, Tukey’ s test, and t test. Results: Thirty-day exposure to all four biomaterials decreased the Flexural strength of root Dentin (P < 0. 05). The four groups were significantly different in terms of the Flexural strength of root Dentin (P = 0. 001). The Flexural strength of root Dentin was significantly lower following exposure to Calcium hydroxide (P = 0. 003), Dentine/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">BioDentine (P = 0. 011), CEM cement (P = 0. 001), and MTA (P = 0. 007) compared to saline. The reduction in strength following exposure to Calcium hydroxide was higher than that in Dentine/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">BioDentine, CEM cement, and MTA groups (P < 0. 05) while the latter three were not significantly different in this respect (P > 0. 05). Conclusions: In general, all four tested biomaterials decrease the Dentin strength although this reduction is more prominent by Calcium hydroxide.
