Analysing inflammatory responses after mandibular third molar extraction: a comparison of suture-less and multiple suture techniques.

purposeThis study aims to compare the outcomes of suture-less and multiple suture closure methods on postoperative pain, swelling, and trismus, and associated complications. MATERIALS AND

methodsThis prospective, randomized clinical trial was conducted at the Department of Oral & Maxillofacial Surgery, Goa Dental College & Hospital. Inclusion criteria encompassed subjects aged between 17 and 55 years, classified as American Society of Anaesthesiologists (ASA) I, with asymptomatic impacted third molars falling within the moderately difficult impaction range (Pederson's difficulty index: 5-7). Study excluded individuals classified as ASA II, III, or IV, those with known or suspected allergies to the anaesthetic solution, immunocompromised patients, and individuals taking medications that could affect healing. Pregnant or lactating females and those with a history of bleeding disorders were also excluded. Wound closure methods were compared: Group A underwent primary closure with silk sutures, while Group B had suture-less closure. Subjects were allocated to the specific groups using a simple randomization method. This involved using a lottery-based random sequence to assign each participant to either Group A or Group B. Pain intensity, facial swelling, and trismus were key outcomes. Secondary outcomes included lingual nerve sensation and postoperative complications. Demographics factors, surgical details, radiographic and perioperative data, and physiological parameters were considered. Non-parametric tests and parametric test (repeated measure ANOVA) were employed. Statistical significance was set at P < 0.05.

resultsAmong 101 participants, both closure techniques exhibited similar outcomes in pain, swelling, and lingual nerve function. However, suture-less closure resulted in significantly less trismus and fewer cases of delayed wound healing.

conclusionsSuture-less method after surgical removal of third molar may reduce trismus compared to multiple sutures. While pain, swelling, and lingual nerve function management were comparable.
