    Polyacrylatecement "Bondal" showed good pulp tolerance in rhesus monkeys. Dental composites "Estic" and "Compocap" caused mild to moderate pulp reactions, which were mitigated by using "Bondal" cement bases.

    Area of Science:

    • Dental Materials Science
    • Biocompatibility Testing
    • Restorative Dentistry

    Context:

    • Assessing the biocompatibility of dental restorative materials is crucial for clinical success.
    • Cervical cavities present unique challenges for material placement and pulp protection.
    • Previous studies have indicated varying degrees of pulp response to different dental materials.

    Purpose:

    • To evaluate the pulp tolerance of two dental composites, "Estic" and "Compocap", and a polyacrylatecement, "Bondal".
    • To determine if a cement base can mitigate adverse pulp reactions to composite restorations.
    • To compare the biocompatibility of "Bondal" versus direct composite application in simulated clinical scenarios.

    Summary:

    • Ninety-seven cervical cavities in rhesus monkeys were restored with "Estic" composite, "Compocap" composite, or "Bondal" polyacrylatecement.

  • "Bondal" demonstrated excellent pulp tolerance.
  • Both "Estic" and "Compocap" elicited slight to moderate pulp reactions when used directly, but these reactions were significantly reduced when "Bondal" cement bases were employed prior to composite placement.

    • Impact:

    • "Bondal" polyacrylatecement is a well-tolerated material for direct pulp capping or as a protective base layer.
    • Utilizing a "Bondal" cement base is recommended to improve the pulp compatibility of "Estic" and "Compocap" composites in cervical restorations.
    • Findings guide material selection for cervical restorations to minimize pulpal inflammation and enhance long-term restoration success.
