“…Other workers have also demonstrated large numbers of microorganisms at the material/cavity wall interface in cavities filled with silicates (29-34) and composites (34)(35)(36)(37). The possibility that bacterial microleakage may complicate the interpretation of puljial responses observed beneath cavities filled with a variety of experimental materials is now widely recognized (5,33,34,(38)(39)(40)(41)(42)(43).…”

The evidence relating microbial microleakage and pulpal inflammation is reviewed. In vitro experiments show that all current dental materials permit fluid microleakage at the material/cavity wall interface. in vivo, this fluid microleakage is accompanied by bacterial growth, unless the material has lasting antibacterial properties. An association does exist between the presence of bacteria at the material/cavity wall interface and the presence of pulpal inflammation. The role of the smear layer m minimizing the harmful effects of microbial microleakage and of chemical toxicity of restorative material is reviewed. Further research should be aimed at eliminating microleakage by the development of more fully adhesive materials or by improving their antibacterial properties.

“…The suitability of the vervet monkey as an experimental model for the study of pulpal reactions to filling materials has been established (Retief & Austin, 1973). In considering the reults of such a study it is necessary to bear in mind the large number of variables which can affect the results (Baume, Fiore-Donno & Holz, 1971). Tyas &.…”

A recently marketed direct filling resin, Isosite, does not have an inorganic filler. This material is offered as a hand-mixed, two-paste system (Isopast) and is also available in capsulated form and as an ultraviolet activated sytem. Since it is well known that direct filling resins used hitherto are capable of causing pulpal irritation, especially in deep cavities, the pulpal response to Isopast was investigated. The experimental animals were twenty-four vervet monkeys {Cercopithecus aethiops). Under general anaesthesia a labial cavity was cut in each of the eight incisor teeth (maxillary and mandibular) of each animal. In each animal two cavities were filled with unlined Isopast, two with Isopast over a lining of calcium hydroxide cement, two with silicate cement and two with zinc oxide/eugenol cement. The animals were killed at intervals of 2, 28 and 56 days. The teeth recovered were decalcified and stained for histological examination. Of the total of 192 specimens sixty-five were discarded, two because of accidental pulpal exposure, one because of leakage and sixy-three because of technical defects in the preparation of the material, leaving 126 specimens available for assessment. This was done independently by three examiners who did not know which materials had elicited the reactions observed. It was found that after 2 days unlined Isopast caused more pulpal disturbance than other materials. After 28 and 56 day intervals lined Isopast caused less disturbance than the other materials. The maker's recommendation that linings should be used is confirmed.
