It worked beautifully, and I used the sample consistently, and successfully, for pulp capping and maintaining vitality in similar cases. Then I ran out. Although the material wasn't on the market yet, I was able to obtain more from Septodont until BIODENTINE was officially launched about a year later.
I have had a perfect track record when using BIODENTINE for asymptomatic cases "no history of pain, normal percussion, and no sensitivity to cold" with carious pulpal exposure.
For endodontic applications, mineral trioxide aggregate (MTA) has been available since 1992. MTA and BIODENTINE have similar chemical formulations: tricalcium silicate with high pH. BIODENTINE could be described as "engineered" MTA. BIODENTINE is easier to use, faster setting, less expensive, and more versatile. MTA does not have the physical properties to be used as a base (only a liner). And with BIODENTINE, I can fill the entire preparation and cover the area without the added difficulty of placing it in a specific location.
I am currently using BIODENTINE differently than I did initially. My basic sandwich technique involves filling half of a preparation with BIODENTINE, then filling the rest with glass ionomer. The 2 materials bond together exceptionally well. With more than 3 years and 200 cases under my belt, I now confidently place crowns on treated teeth within a month, knowing that vitality will be maintained with BIODENTINE. With that first case, I waited 8 months, because I didn't believe it worked. I have never had to go back in after crown placement. My only failures have been caused by lack of patient compliance by not returning for a final restoration.
BIODENTINE helps preserve pulp, and prevent postoperative sensitivity and clinical failures. I couldn't imagine practicing the dentistry I do without BIODENTINE and would recommend it unquestioningly to my colleagues.
