BACKGROUND: Suture is the surgical final act in most of oral surgery’s procedures. Quality of advisable healing after the operation depends on its efficiency. Suture must not be cause of inflammation, both in direct way and indirect. The objective of this study is to compare the bacterial colonization on different suture’s materials after a third molar’s extraction.
METHODS: 30 patients were randomly selected among people going under third molar extraction; they were divided into 3 groups and one suture type was used on each group. After 7 days distal stitches were removed by a single operator, placed in physiologic solution and analyzed after 2 or 3 hours. Patients followed the same post surgical protocols; materials used were: Silk 4/0 ETHICON, Dafilon©️ BIBRAUN 4/0, Safil©️ BIBRAUN 4/0.
RESULTS: The amount of cocci and bacilli on the sutures analyzed shows that silk (Silk by ETHICON®) is the higher level of retention material where monofilament (Dafilon by BIBraun®) is the lower. There is a difference between monofilament and poliglicolic material (Safil by BIBraun®): the first one is less retentive but not statistically significant.
CONCLUSIONS: A less plaque retention, and consequently a fewer bacterial presence, is crucial to minimize the inflammatory process and allow a better tissue healing. Since the capability of brushing and, of course, the final personal hygiene is dependent from different variables, we must use surgical protocols able to minimize the effect of improper cleaning on the healing process: this statement implies the use of low plaque retention materials. Suture is the final surgical act and deliver a suture with monofilament or poliglicolic threads can help reducing bacterial concentration and therefore allow a faster and better healing.
