Summary

This is a triple-blind randomized controlled trial conducted at the Department of Oral and Maxillofacial Surgery, Subbaiah Institute of Dental Sciences, Shimoga. The study enrolls 176 adult patients aged above 18 years belonging to ASA class 1 or 2, requiring intra-alveolar extraction of non-restorable carious teeth with radiographic evidence of periapical abscess of less than 1.5 cm in diameter. Patients are randomly allocated into two equal groups of 88 each. Group A receives postoperative Amoxicillin 500 mg thrice daily for 5 days in addition to standard analgesics. Group B receives only standard analgesics with no antibiotic prescription. The primary outcome measure is wound healing assessed on postoperative day 5 using a modified Landry Wound Healing Index evaluating gingival tissue color, response to palpation, presence of granulation tissue, and suppuration.

Conditions

  • Periapical Abscess

Interventions

DRUG

Amoxicillin 500mg

A single operator performs intra-alveolar extraction under local anaesthesia using 2 per cent Lignocaine with Adrenaline 1 in 200000. The procedure involves detachment of gingival mucoperiosteum without incisions, forceps or elevator extraction without ostectomy, saline irrigation, manual compression of socket and placement of moist gauze pack for pressure. Postoperatively, Amoxicillin 500 mg is administered to patients in Group A, thrice daily after food for 5 days.
