Pulp response to Enamelite restorations in teeth of rhesus monkeys

The average magnitudes of cellular displacements, superficial responses, and deep responses were less for specimens restored with ZOE than for Enamelite specimens at the 1 week postoperative period. Of 20 teeth treated, three abscesses were found in the 1 week Enamelite postoperative period when the remaining dentin was 0.3 mm. or less. This indicates the presence of ingredients that are toxic to the pulp when there is little remaining dentin or when the material is placed directly over an exposure. Teeth restored with Enamelite in the 6 week group had values comparable to the ZOE teeth for the same time period.
