2 Comparison between BioDentine and MTA. Odabaş et al evaluated the bond strength of Biodentine with different etching systems. There was no difference found when tested at the same time intervals (12 minutes and 24 hours). On the other hand, different time intervals showed that the etch and rinse adhesive had the lowest bond strength at 12 minutes while the 2-step self-etch had the highest with the 24-hour duration. Another study done in 2013 by Josette Camilleri proved that total etch, and rinse was more effective than self- etch. 4.BioDentine in Direct & Indirect Pulp Capping procedures: 4.1 Direct Pulp Capping Direct pulp capping is a treating procedure of an exposed pulp using dental materials that promotes the formation of tertiary (reparative) dentine and maintenance of pulp. It can also be considered as an alternative way to avoid vital pulp excision. However, vital pulp excision success rate is much higher than the direct pulp capping. Before treatment, the pulp should be asymptomatic as in clear from bacteria or toxins, and bleeding should be controlled by sodium hypochlorite for example. Any remnants might cause treatment failure. A study was done on the maxillary and mandibular sound 3rd molars of twenty-eight patients for 6 weeks, and pulp vitality was examined prior extraction. After teeth cleaning, disinfection, local anesthesia and rubber dam are applied, class 1 cavities were prepared and an exposure around 1.2 mm in diameter was done. The teeth were divided into Biodentine and MTA experimental groups and one control group for comparison. Within a week, patients returned for the application of the final composite restoration. After 6 weeks, teeth were extracted. After extraction teeth were fixed and demineralized, then samples were evaluated under normal and ultraviolet light. The results showed that the pulp-dentin response was the same in both groups, where dentin bridge was formed directly under the capping material in site of exposure. Odontoblast cells near dentinal bridge were discovered with dentinal tubules. In conclusion Biodentine is considered an alternative material to MTA in treating vital pulps. However, furthe>GET ANSWER
