CLINICAL AND EXPERIMENTAL STUDIES OF SURGICAL SUTURE MATERIALS IN THE ORAL TISSUE

5 different suture materials were tested in the oral cavity of 27 patients and 24 rabbits to determine the degree of handling characteristics and the tissue reactions. Tissue reactions were graded clinically at 1, 3, 5 and 7days after : suturing in patients and histologically 1, 3, 5, 7, 14 and 21days after suturing in rabbits. The results were as follows; 1. On the pliability and the knot security, the polyfilament suture materials (Silk, Nylon II, P.G.A.) were better than the monofilament suture materials (Catgut, Nylon I), but in case of P.G.A., a loose first knot couldn t be tightened by pulling hard on the second, and occasionally came untied. 2. The monofilament suture materials evaluted (Catgut, Nylon I) resulted in a milder tissue response than the polyfilament suture materials, otherwise, the polyfilament P.G.A. suture showed the finding of favorable mild reaction. 3. In the polyfilament suture materials (Silk, Nylon II, P.G.A.), the Wicking Action was observed which could result in the transmission of a various number of oral flora to the depth of the wounds. 4. Oral epithelium proliferated along the course of the suture tracts, tending to isolate and exteriorize the source of inflammation, and to create a fistulous tract, this was observed at 5days 5. Chromic Catgut and P.G.A. sutures are absorbable, but remains longer than desired in the oral cavity, so they can be used in the same manner as nonabsorbable suture materials.
