Direct pulpcapping with a new material biodentine: a case report.
A new bioactive cement, Biodentine[TM] n (Septodont, St. Maur-des-Fosses, France), was recently launched on the dental market as a dentin substitute. It shares both its indications and mode of action with calcium hydroxide, but does not have its drawbacks. Biodentine[TM] consists of a powder in a capsule and liquid in a pipette. The powder mainly contains tricalcium and dicalcium silicate, the principal component of Portland cement, as well as calcium carbonate. Zirconium dioxide serves as contrast medium. The liquid consists of calcium chloride in aqueous solution with an admixture of polycarboxylate. The powder is mixed with the liquid in a capsule in the triturator for 30 seconds. Once mixed, Biodentine[TM] sets in about 12 minutes. During the setting of the cement calcium hydroxide is formed. The consistency of Biodentine TM reminds of that of phosphate cement. (3)
In summary, Biodentine[TM] is both a dentin substitute base and a cement for maintaining pulp vitality and stimulating hard tissue formation, i.e. the formation of reactive or reparative (tertiary) dentin. The case report illustrates the use of Biodentine[TM] for direct pulp capping. (4)
CASE REPORT: A 22 Year old male patient reported to the Department of Conservative Dentistry and Endodontics, Rajarajeshwari Dental College and Hospital, Bangalore, Karnataka, India. With the chief complaint of decay in the lower left back tooth region. In the initial examination revealed a deep carious lesion. The teeth were tested positive on pulp vitality and negative on percussion. Radiographic evaluation showed a deep carious lesion involving enamel, dentin and approximating the pulp. After thorough information to the patient about the treatment consent was obtained block with lignocaine (2%) was given followed by rubber dam application. Following cavity preparation the carious dentin was completely excavated with slow speed hand piece and spoon excavator. In the process the pulp cavity was exposed iatrogenically. Clinically the pulp tissue was vital without any major bleeding, so that maintenance of tooth vitality by direct pulp capping was decided upon. NaOCl (2.5%) was applied for hemostasis, clearing and disinfecting the cavity. Biodentine[TM] was chosen for direct pulp capping. Mixed as recommended by the manufacturer, and was applied on the exposed pulp tissue as direct capping. About twelve minutes after mixing, when the material had set the cavity was restored with composite. The outcome of the performed treatment was evaluated by pulp vitality tests and Radiographic evaluation for any periapical changes at 1month, 3month and 6 months interval. At the end of 6-month follow up: Clinically teeth were asymptomatic. The teeth responded positive for pulp vitality and negative for percussion tests. The radiographic evaluation showed no periapical changes.
DISCUSSION: The primary aim of pulp capping material is to induce a specific hard tissue formation by pulp cells that seal the exposure site and ultimately contribute to continued pulp vitality. It is known that calcium silicate cements have the ability to release calcium and hydroxyl ions and to form hydroxyapitite crystals on the surface after contact with phosphate containing liquids like body fluids. It can be assumed that Biodentine exhibits the same effects as calcium hydroxide, Due to the release of calcium and hydroxyl ions, when in contact with water. (5) Hence, Biodentine is biocompatible it does not damage pulpal cells, and is capable of stimulating tertiary dentin formation. Compared to other materials such as Mineral Trioxide Aggregate, Biodentine is less technique sensitive (5). Setting time of biodentine is 12-15 mins, compared to MTA which has a setting time > 24 hrs. Unlike other Portland cement-based products, it is sufficiently stable to be used for pulp protection. Used for pulp capping, the material offers some benefits versus calcium hydroxide: It is mechanically stronger, less soluble and produces tighter seal. This qualifies it for avoiding three major drawbacks of calcium hydroxide, Material resorption, Mechanical instability and failure of preventing microleakage. Replacement of the dentin layer and enamel layer with a composite restoration was performed during the same appointment. As it is important to seal the cavity against bacterial invasion in a one-stage procedure (6). There is extensive evidence documenting that composite fillings are leak proof, few pertinent data are available for biodentin yet.
CONCLUSION: Biodentine[TM] is an interesting product, with the potential of making a major contribution to maintaining pulp vitality in patients judiciously selected for direct pulp capping.
