BIOCOMPATIBILITY OF OPTIBOND AND XR-BOND ADHESIVE SYSTEMS IN NONHUMANPRIMATE TEETH

This study evaluated the histologic responses of two different adhesiv e systems on the teeth of seven healthy adult monkeys. Class V cavitie s in 128 teeth were observed at 7, 21 to 27, and 90 to 97 days. Statis tical data showed no significant differences in pulp inflammation betw een the Optibond (Kerr), XR-Bond (Kerr), and IRM (Caulk) groups in pul ps at the three time intervals, Some odontoblastic disruption and infl ammation was seen in pulps restored with XR-Primer at the three time i ntervals. Pulp healing was similar in teeth treated with both direct-c apped Optibond and calcium hydroxide, and there was no significant inc rease in pulpal inflammation with time. No abscesses or necrotic pulps were seen in any teeth. Optibond and XR-Bond adhesive systems are bio logically acceptable in nonhuman primate pulp tissues.
