Evaluation of the tissue reaction of five different suture materials in rabbit palatal mucosa

Abstract

The objective of this study was to evaluate local tissue reactions at silk, chromic gut, polypropylene, polyester, and polyglactin 910 suture materials for intraoral applications. One hundred eighteen sutures were placed into the palatal mucosa of 26 male New Zealand rabbits so that each animal included all five biomaterials. The animals were fed a soft diet and decapitated 2, 4, or 8 days after suture placement. Soft tissue specimens including suture materials were prepared for light microscopy to determine the inflammatory zones including eosinophil infiltration on the suture tract. No significant differences were observed in the sutural zone diameter (Z1) between the suture materials at the 2nd day. At the 4th day, polypropylene and catgut had a lesser Z1 diameter compared to polyglactin 910. Dacron presented the widest mean Z1 diameter compared to polyglactin 910 (p<0.01), catgut (p<0.01), polypropylene (p<0.05) and silk (p<0.05) at the 8th day. On the day 8, the largest mean Z2 diameter was observed in dacron group compared to the mean Z2 values of catgut (p<0.05) and polyglactin 910 (p<0.01). Also the mean Z2 values of silk were significantly wider compared to polyglactin 910 (p<0.05). There was no difference between the eosinophil scores of the suture materials (p>0.05). Within the limitations of the present study, it may be said that silk and dakron sutures apparently induced more severe inflammatory reactions. When selecting a suture material for intraoral use the surgeons should take into consideration the tissue reaction caused by materials. Keywords

Is tissue glue an alternative to sutures in impacted third molar surgeries?

“…They tend to accumulate debris and cause irritation often necessitating manual removal. 10,11 This has led to the introduction of easier way of wound closure by using tissue adhesives. 12 Cyanoacrylates are bio adhesives (plastic adhesives) that were discovered by Ardis (a German chemist) in 1949 and rst used for surgery by Coover et al in 1959.…”

“…Tiga parameter yaitu kemerahan, kebengkakkan, dan keropeng untuk menunjukkan angka kesembuhan dari 16 ekor kelinci harus menurun (0) atau sama sekali tidak ada ketiga parameter tersebut sampai hari ke-14, sedangkan pertumbuhan rambut hari ke-1-14 menunjukkan terjadi pertumbuhan pada 16 ekor kelinci maka dinyatakan sembuh.
