Abstract

Background: Impacted mandibular third molars harm periodontal health of second molars' distal aspect. Primary wound healing is crucial for prognosis, with horizontal mattress sutures being more effective than simple sutures. Objectives: To evaluate the primary wound healing and distal periodontal status of second molars after impacted mandibular third molar surgery between mattress and simple suture groups at 1 and 3 months. Material and methods: A study on 36 patients with bilaterally impacted mandibular third molars. Each side was sutured with either horizontal mattress or simple sutures. Healing (CSR scores at 7/14 days) and periodontal health (PlI, GI, PD, alveolar crest height) were evaluated pre-surgery, 1, and 3 months post-surgery. Results: In the mattress suture group, CSR scores were 2.67 ± 0.16 on day 7 and 4.50 ± 0.25 on day 14; In the simple group, they were 1.33 ± 0.25 and 1.83 ± 0.30. At 3 months postoperatively, Plaque Index (PlI) decreased from 2.39 ± 0.11 to 1.83 ± 0.06 in the simple group and from 2.39 ± 0.12 to 1.44 ± 0.08 in the mattress group; Gingival Index (GI) reduced from 1.83 ± 0.15 to 1.39 ± 0.11 in the simple group and from 1.83 ± 0.13 to 1.17 ± 0.12 in the mattress group; Probing Depth (PD) decreased from 5.56 ± 0.21mm to 5.17 ± 0.17mm in the simple group and from 5.50 ± 0.14mm to 4.56 ± 0.10mm in the mattress group; The distance from the cementoenamel junction to the alveolar crest declined from 4.42 ± 0.17mm to 4.31 ± 0.17mm in the simple group and from 4.29 ± 0.16mm to 4.02 ± 0.15mm in the mattress group. Conclusion: Mattress sutures are more effective than simple sutures in promoting healing and improving periodontal outcomes distal to the second mandibular molar after third molar surgery.
