Management of gingival recession with modified coronally advanced tunnel technique: Case report

Introduction: Gingival recession is characterized by apical migration of the gingival margin from the cementoenamel junction (CEJ), with concomitant exposure of the root surface. Teeth with gingival recession often experience pain in response to thermal, chemical, and tactile stimuli to the exposed dentine. This is known as dentin hypersensitivity. Dentin hypersensitivity is characterized by exposed dentinal tubules most often due to gingival recession and loss of cementum through erosion, abrasion, or other factors. Patient’s main concerns: A-20-years-old male patient visited to Periodontics Clinic Dental Hospital Airlangga University with the main complaint of dentin hypersensitivity in the upper right second premolar. The Systemic is good, had no history of allergies and did not smoke. Important clinical findings: The recession measured 1 mm facially on the maxillary right second premolar. Case and Management: Prior to surgery, scaling and root planing was performed to eliminate debris and calculus. Two weeks afterward, modified coronally advanced tunnel technique was done for dentin hypersensitivity treatment. One month evaluation, dentin hypersensitivity disappeared. Conclusion: Modified coronally advanced tunnel technique was the appropriate treatment to treat dentin hypersensitivity. This technique achieved healthy keratinized tissue and coverage of the root surface.
