Abstract

Sutures are medical devices used in surgery. They serve as tissues stabilizers in contact with or near to the surgical site without compromising the healing process. They must keep their physical properties for the necessary time, in particular tensile strength. In view of the wide variety of references offered by all specialtys combined, which supply sutures with all materials described, whose use is indicated for all surgical procedures. The objective of this work is to evaluate the tensile strength of absorbable and non-absorbable sutures for a period of 10 to 28 days under conditions simulated by the oral route. 5 sutures materials were tested with a metric diameter of 1.5 and 4.The tensile strength test was used according to the protocol of the European Pharmacopoeia (Eur.Ph.9.5). 5 fragments of each material were measured before and after their immersion in Artificial Saliva (AS). In AS, the Polypropylene suture significantly maintained (p = 5%) its tensile strength compared to that of Polyamide. For absorbable sutures, a loss of more than 70% of their initial strength was marked on the 7th day of immersion. In view of the results obtained, during oral surgical operations, the material of choice is in favor of Propylene.

Highlights

Surgery has continued to progress in recent years
Various factors make suturing a different phenomenon in the oral environment compared to other parts of the body, due to the type of tissues, the constant presence of saliva, high tissue vascularity, as well as the functions related to speech, chewing, and swallowing
5 suture biomaterials were chosen according to their use in dental surgery and whose characteristics are shown in Table 2, 3, and 4

Summary

Introduction

Whether for therapeutic, aesthetic or tissue management purposes, post-surgical healing remains a key point common to all types intervention. Various factors make suturing a different phenomenon in the oral environment compared to other parts of the body, due to the type of tissues, the constant presence of saliva, high tissue vascularity, as well as the functions related to speech, chewing, and swallowing. The suture should generate a tissue reaction and a minimum tensile force. It must ensure non-capillarity, security of the knot and easy handling. The choice of the suture must be based on the optimum tensile strength, handling, penetration and glide, offering the practitioner ease of placement and realization of stitches while guaranteeing the preservation of the sutured tissues
