Abstract

Abstract. A new composite restorative material, Enamelite, has recently been introduced for the conservative treatment of cervical erosion and hypoplastic enamel surfaces. The pulpal response elided by the restorative material was investigated in teeth of the vervet monkey and compared to a modified zinc oxide‐eugenol cement.Buccal or labial Class V cavities were prepared in 128 teeth in six vervet monkeys. The teeth in contralateral segments were restored with the restorative and control materials, respectively. The experimental animals were killed at 4, 14 and 42 days.The restorative and control materials exhibited about the same minimal degree of cellular displacement and inflammatory response at each of the three postoperative time intervals.The percentage of specimens with reparative dentin increased progressively with time. At all three intervals the restorative material elicited a greater response than the control zinc oxide‐eugenol cement.The results suggest that the clinical application of the restorative material on cervical eroded or hypoplastic enamel surfaces without a protective lining is a safe procedure.
