The Comparison of Oral Mucosal Clinical Reactions to PVDF and Silk Sutures in Albino Rabbit

This study was carried out in order to compare the oral mucosal reactions to silk and poly vinylidene fluoride (PVDF) suture materials in albino rabbit. Twenty-one mature male albino rabbits were selected and under general and local anesthesia suture materials were placed randomly at right and left side of vestibular area of maxillary jaw. The animals were divided into three equal groups based on the time of suture removal (۳, ۵ and ۷ days after suturing), and inflammatory reaction of the oral mucosa at sutured area was scored clinically and sutures were removed. The sutured areas in all of the animals were observed ۱۴ days after suturing and the inflammatory reaction was scored again. Wilcoxon and Kruskal-Wallis tests were used for data analysis. Results showed that in all time intervals, inflammatory reactions to PVDF sutures were significantly milder comparing to silk sutures (P<۰.۰۵). Also, later suture removal increased the inflammatory reaction and healing decreased. It can be concluded that in oral surgeries PVDF suture due to creating milder tissue reactions is preferable to silk suture.
