The aim of this study was to compare the bacterial colonization  counts of chromic and Polyglycolic Acid (PGA) sutures in the context of oral surgery. Materials & Methods: This randomized split-mouth clinical study with laboratory microbiological analysis included 56 patients aged 17–20 years who underwent bilateral surgical extraction of fully impacted mandibular third molars. Each patient received chromic catgut sutures at one surgical site and PGA sutures at the contralateral site, with the allocation of suture materials to the right and left sides determined using a computer-generated randomization sequence. Sutures were removed 1 week after surgery and subjected to aerobic and anaerobic bacterial culture. Mean colony counts were compared between the two suture materials using repeated-measures analysis of variance. (α=0.05) Results: PGA sutures showed significantly lower bacterial colonization. Mean aerobic colony counts were 3.93 × 10^5 for PGA versus 6.54 × 10^5 for chromic sutures (P = 0.00002). Anaerobic colony counts were 1.98 × 10^5 for PGA versus 3.35 × 10^5 for chromic sutures (P = 0.003). Combined aerobic-anaerobic counts were 5.91 × 10^5 for PGA versus 9.90 × 10^5 for chromic sutures (P =0.0001). <h1>Conclusion: In this study, PGA sutures showed significantly lower levels of aerobic, anaerobic, and total bacterial colony counts compared to chromic catgut sutures. However, further research is needed to confirm the results clinically. </h1>  </div> </div> </div> 0 0 http://cofs.khuisf.ac.ir/browse.php?a_code=A-10-1-89&slc_lang=en&sid=1 Mohammadreza Amin 10031947532846001619 10031947532846001619 No Faculty of Dentistry, Isf.C, Islamic Azad University, Isfahan, Iran Mehdi Abrishami 10031947532846001620 10031947532846001620 Yes Department of Oral & Maxillofacial Surgery, Faculty of Dentistry, Isf.C, Islamic Azad University, Isfahan, Iran Arezou Tahmourespour 10031947532846001621 10031947532846001621 No Departments of Basic Medical Sciences and Medical Biotechnology, Faculty of Dentistry,Isf.C, Islamic Azad University, Isfahan, Iran Asghar Nazer 10031947532846001622 10031947532846001622 No Department of Oral & Maxillofacial Surgery, Faculty of Dentistry, Isf.C, Islamic Azad University, Isfahan, Iran
