“…In contrast to reports from former implantation studies the operative trauma appeared rather marked in the present study (Dixon & Rickert 1933, Mitchell 1959, Hall & Mitchell 1960, Boyd & Mitchell 1961, Torneck 1961, Guttuso 1963, Guglani & Allen 1965. The short term implants did not allow a finer distinction between the test materials.…”

“…About 5 % free eugenol can be found in zine oxide/eugenol in the set stage (Molnar 1967), As the material disintegrated, the free eugetiol could sustain the irritation in the connective tissue. This finding is in contrast to Hall & Mitchell (1960) and Guglani & Allen (1965) who indicated that the reactions at two, seven and 14 days were "mild" for zinc oxide/ eugenol. It may be argued that reactions to long term implants of periodontal dressings are clinically irrelevant because dressings seldom remain in place for more than 10 days.…”

“…The short term implants did not allow a finer distinction between the test materials. In no case could the reaction be characterized as "slight" adjacent to short term implants of periodontal dressings as previously reported (Mitchell 1959, Hall & Mitchell 1960, Guglani & Allen 1965. However, the scoring system seemed well suited to evaluate long term implants Table 3 Tissue reactions to long term implants evaluated according to a pre-selected scoring system.…”

“…The reactions to periodontal dressings have also been tested with implantation techniques. Small disk-shaped pellets of the dressings have been implanted (Hall & Mitchell 1960, Baer & Werthefmer 1961, Guglani & Allen 1965, Frisch & Bhaskar 1967, or the material has been injected into a pocket made in the connective tissue (Boyd & Mitchell 1961). No study of the tissue reaction has been performed following the introductioti of such materials into tubes according to recommended procedures (American Dental Association 1976).…”

Polyethylene tubes filled with various dental materials were placed as subcutaneous implants in rats. A scoring system for no, slight, moderate and severe reaction was established on the basis of the tissue response to a variety of materials for the evaluation of long term implants (30 or 90 days). Short term implants (7 or 14 days) were evaluated by deciding whether or not an effect from the material could be found in addition to the operative trauma. The scoring system was used to evaluate the reactions to three periodontal dressings. Tissue from the short term implantation periods exhibited marked reactions to most implants. Long term implantation revealed that a difference in the tissue response to the three dressings was present, For two of the materials the initial irritation was followed by an innocuous state, but from the third dressing a continuous irritation of the tissue was observed.

“…Kreth et al (1966) have demonstrated the irritant nature of aqueous extracts of dressing materials in current use on cultures of He-La cells. Several animal studies have also shown that the intact dressings themselves can cause cell damage in subdermal connective tissue (Gugliani .& Allen 1965), parietal bone (Baer & Wertheimer 1961), and periodontium (Waerhaug & Loe 1957).…”

Twenty-seven proprietory periodontal dressings were applied to the lower labial segments of 18 subjects showing low levels of gingival inflammation when assessed by the Gingival Index system at the time of application. Specimens of each dressing type were subsequently removed at intervals ranging from 3 h to 5 days. The material adhering to the deep surface of the dressing was examined by light, transmission and scanning electron microscopy and was shown to be a complex heterogeneous structure consisting of large intact epithelial cell sheets and oral bacteria in a proteinaceous matrix. Possible mechanisms which could contribute the epithelial cell and protein components to this structure were discussed. It was concluded that the dressings themselves caused little damage to the normal periodontium but could be associated with increased levels of inflammation at longer time intervals because of bacterial growth. The significance of these findings to current clinical practice is discussed.
