    Notes: Abstract 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.

    Effect of cutting speeds and a cavity liner on the pulpal response to Nobetec® (1981)

    Notes: Abstract The investigation was undertaken to determine the response to Nobetec®, a modified zinc oxide-eugenol cement, widely used as a negative control material in pulpal studies, under conditions of high- and low-speed cavity preparation, with and without a cavity liner Dycal®. The pulpal responses were evaluated at intervals of 2 days, 2 weeks and 8 weeks in the permanent maxillary and mandibular incisors in 26 vervet monkeys using labial Class V cavities prepared in 208 teeth. Nobetec® was found to be more irritant to the dental pulp than Dycal® although this difference was not statistically significant and the degree of irritation was low. The pulpal irritation caused by high- and low-speed cavity preparation was similar and choice of speed should be a matter of personal preference.
