BIOCOMPATIBILITY OF CLEARFIL LINER BOND-2 AND CLEARFIL AP-X SYSTEM ONNONEXPOSED AND EXPOSED PRIMATE TEETH

Objective: Recent studies have demonstrated that acid etching of vital dentin and pulpal tissue does not retard pulpal healing, odontoblasto id cell differentiation, or dentinal bridge formation when the pulp is capped with adhesive resins. The purpose of this study was to evaluat e the pulpal response in nonexposed and exposed monkey pulps to treatm ent with the Clearfil Liner Bond 2 and Clearfil AP-X system. Method an d materials: Class V and Class I cavities in nonexposed and exposed pu lps were observed at 7 or 8, 27, and 97 days. Results: There were no d ifferences in pulpal inflammation between the Clearfil Liner Bond 2/Cl earfil AP-X specimens and calcium hydroxide controls in either Class V or Class I cavities at the various time periods. Conclusion: Clearfil Liner Bond 2 and Clearfil AP-X system is not toxic to either nonexpos ed or exposed pulpal tissues when placed according to manufacturer's d irections.
