A new visible light‐cured composite resin, Fotofil®, has been developed for the esthetic restoration of anterior teeth. The pulpal responses elicited by this material in unlined cavities and cavities lined with Dycal® were compared with those elicited by a negative control consisting of modified zinc oxide‐eugenol cement Nobetec® and a silicate cement Syntrex®. The pulpal responses were evaluated in the permanent maxillary and mandibular incisors in vervet monkeys using labial Class V cavities prepared in a total of 240 teeth. Two teeth were filled with each material in each monkey. Groups of 10 monkeys were killed at intervals of 2 days, and 2 and 8 weeks after restoration of the teeth. The most severe pulpal responses were elicited by the unlined Fotofil® and Syntrex® restorations at all three time intervals. The Dycal® lined Fotofil® restorations elicited a milder pulp response than the Nobetec ® at 2 days and 2 weeks. No pulpal response was elicited by the latter two materials at 8 weeks. These results clearly showed that Fotofil® and Syntrex® are irritant to the dental pulp up to 8 weeks. The placement of a Dycal® liner beneath Fotofil® restorations reduced the pulpal irritation elicited by this material to levels which were lower than those elicited by the Nobetec® control at 2 days and 2 weeks.
