Summary
Polyglycolic acid sutures caused less gingival inflammation than black silk sutures in oral surgery patients. Chlorhexidine mouthwash did not significantly alter microbial presence on either suture type.
Area of Science:
- Oral Surgery
- Biomaterials Science
- Inflammation Research
Background:
- Suture material selection impacts post-operative inflammation and wound healing.
- Understanding the inflammatory potential of commonly used oral sutures is crucial for patient outcomes.
Purpose of the Study:
- To compare the inflammatory reaction elicited by black silk and polyglycolic acid sutures in the oral environment.
- To assess the effect of chlorhexidine solution on microbial presence on sutures.
Main Methods:
- A randomized clinical study involving 55 oral surgery patients (aged 9-76).
- Suture samples (black silk and polyglycolic acid) were collected 8 days post-application.
- Bacterial counts and light microscopy (x100) were used to evaluate inflammatory response.
- Patients used 0.2% chlorhexidine solution for wound disinfection.
Main Results:
- Polyglycolic acid sutures demonstrated a lower inflammatory reaction in gingival tissues compared to black silk sutures.
- Wound conditions were deemed acceptable at 8 days post-surgery for both suture types.
- Chlorhexidine solution usage did not significantly influence the presence or types of microorganisms on either suture material.
Conclusions:
- Polyglycolic acid may be a preferable suture material for reducing oral inflammatory responses.
- Both suture types, when used with chlorhexidine, resulted in acceptable wound healing.
- Chlorhexidine's impact on suture-associated microbial colonization in this context was minimal.
