Abstract

Aim: The aim of the study was to evaluate the tensile strength of surgical Absorbable and Non-absorbable suture materials.

Materials and Methods: A total of 360 samples of absorbable and non absorbable suture materials were tested for tensile strength in a simulated oral environment using INSTRON machine on 1st, 7th and 14th day. Absorbable suture materials Trugut (Catgut), Truglyde (Polyglycolic Acid), PD Synth (Polydioxanone), and non-absorbable sutures Trusilk(Silk), Trubond (Polyester),Trulene (Polyproplene) of three different dimensions (3-0,4-0,5-0 respectively) were used.

Statistical analysis: Mean and standard deviations were obtained by using Descriptive statistical method. Repeated measure by ANOVA and Man Whiney U test were used to compare the degradation of tensile strength.

Results: Among absorbable sutures, Catgut 5-0 showed maximum deterioration of tensile strength with a P value of 0.043 and Polyglycolic acid 3-0 showed minimum deterioration with a P value of 0.050 whereas among non-absorbable sutures Silk 4-0 showed maximum deterioration of tensile strength with a P value of 0.005 and Polypropylene 3-0 showed minimum deterioration with a P value of 0.041.

Conclusions: In this study, Truglyde 3-0(absorbable sutures) and Trulene (non-absorbable suture) 3-0 will be the preferred material for the periodontal surgeries where sutures need to be retained for longer periods. Trugut 5-0 (absorbable sutures) and Trusilk 4-0 (non-absorbable sutures) can be used in minor surgical procedures since there is significant deterioration in tensile strength in 7 days.

Key-words: Suture materials, absorbable suture materials, non-absorbable suture materials, tensile strength.
