This</span></span></span></span><span style="line-height:200%"><span new="" roman="" times=""> study aimed to investigate the effect of 0.12% chlorhexidine on the incidence of dry socket and the associated pain in patients undergoing surgery for maxillary and mandibular third molars. </span></span></span></span><br> <span style="line-height:200%"><span calibri=""><b><span style="line-height:200%"><span new="" roman="" times="">Materials and Methods:</span></span></b><span style="line-height:200%"><span new="" roman="" times=""> In this clinical trial, 105 patients with non-impacted or partially impacted wisdom teeth were selected and divided into three groups.</span></span> <span style="line-height:200%"><span new="" roman="" times="">The first group used chlorhexidine mouthwash for seven days prior to surgery, while the second group used it for seven days afterward at 12-hour intervals. The third group (control) used gauze soaked in standard normal saline (0.9% sodium chloride) at the wound site. Cases of dry socket occurrence were recorded. Data were analyzed using chi-square, Fisher&#39;s, and Kruskal-Wallis tests.</span></span></span></span><br> <span style="line-height:200%"><span calibri=""><b><span style="line-height:200%"><span new="" roman="" times="">Results:</span></span></b><span style="line-height:200%"><span new="" roman="" times=""> The incidence of dry socket was 3.4% in the first group, 5.1% in the second group, and 5.4% in the control group, with no statistically significant difference between the groups (p>0.05). Additionally, gender, oral hygiene level, smoking, type of surgery, and surgical site had no significant impact on the occurrence of this complication (p>0.05).</span></span></span></span><br> <span style="line-height:200%"><span calibri=""><b><span style="line-height:200%"><span new="" roman="" times="">Conclusion:</span></span></b><span style="line-height:200%"><span new="" roman="" times=""> The use of chlorhexidine does not have a significant effect on preventing the occurrence of dry socket. However, there are no contraindications for its use.</span></span></span></span></span><br> &nbsp;</div> 22 27 http://cofs.khuisf.ac.ir/browse.php?a_code=A-10-1-51&slc_lang=en&sid=1 Nima Aghaei 1003194753284600826 1003194753284600826 No Faculty of Dentistry, Isf.C, Islamic Azad University, Isfahan, Iran Mehdi Abrishami 1003194753284600827 1003194753284600827 Yes Department of Oral & Maxillofacial Surgery, Faculty of Dentistry, Isf.C, Islamic Azad University, Isfahan, Iran Somayeh Abbasi 1003194753284600828 1003194753284600828 No Department of Mathematics, Isf.C, Islamic Azad University, Isfahan, Iran Behrooz Moradbeig 1003194753284600829 1003194753284600829 No Department of Oral & Maxillofacial Surgery, Faculty of Dentistry, Isf.C, Islamic Azad University, Isfahan, Iran
