ABSTRACT
Aim: The purpose of this study was to evaluate the tensile strength of surgical absorbable sutures over a period of 14 days in different solutions. Methods: A total number of 90 samples were divided into 2 groups [45 (4-0 chromic catgut) and 45 (4-0 monocryl)]. These groups were then further divided into 3 subgroups with 15 samples of each dispensed in 3 different solutions (Artificial Saliva, Chlorhexidine 0.2% and Listerine). From each subgroup 5 samples were examined at 1st day, 7th day and 14th day. Samples were then placed in an incubator at 37°C. Once tied, the sutures will carefully slid off the rubber tubing for testing. The tensile strength of the knot was evaluated by using Universal Testing machine. Results: Tensile strength of chromic catgut (Group A) was highly statistically(p<0.001) lower as compared to monocryl (Group B) and at various time intervals (Day 1, Day 7 and Day 14) respectively in different solutions. On intragroup comparison, it was observed that there was a highly statistical significant decline in tensile strength in all three media as time of immersion increases. Conclusions: Tensile strength of monocryl was statistically higher as compared to chromic catgut. Listerine mouthwash largely reduces the tensile strength of chromic catgut (4-0) & monocryl (4-0) than chrohexidine and artificial saliva.
Keywords: Tensile strength, chromic catgut, monocryl, Artificial saliva, 0.2% chlorhexidine, Listerine.
