Pulp reactions in human teeth to tooth colored filling materials.

Abstract

In each of 49 intact premolars from children between 9 and 15 years of age, one buccal and one lingual cavity were prepared. The 98 cavities were filled with either Silicap, Sevriton Simplified or Adddent XV. After 2 weeks 19, and after 6 months 30 of the teeth were extracted. The histologic investigation included remaining dentin, reduction in the number of odontoblasts, inflammatory cells, necrosis, tertiary dentin and bacteria. After 2 weeks a loss of odontoblasts and inflammation was seen beneath two-thirds of the cavities, and small necrotic areas in 11 of the 38 instances. After 6 months the loss of odontoblasts was a little more pronounced, the inflammation a little less, and necrosis could not be observed. Tertiary dentin was registered beneath most of the cavities after 6 months. The reactions to the three filling materials were quite similar in quality and quantity. The amount of remaining dentin influenced the degree of inflammation and amount of tertiary dentin after 6 months beneath cavities filled with Silicap, and inflammation after 2 weeks and 6 months beneath Addent. Bacteria were observed in nearly all cavities 6 months after the treatment.
