Abstract
Objective: To report a clinical case of necrotizing gingivitis in a child, with a clinical diagnosis of Chikungunya. Case details: 8-year-old male patient who visited the Dental School Clinic at the Federal University of Campina Grande reporting “gum pain”. Clinically, the presence of necrosis limited to the buccal gingival margin and the tips of the interdental papillae in the upper antero region was observed. Characteristic signs of the disease were identified, such as: pain, difficulty in cleaning and feeding, gingival necrosis, fetid odor and candidiasis. A conservative treatment was performed with scraping and coronary smoothing, cleaning with hydrogen peroxide at 10 volumes and prescription of mouthwashes with 0.12% chlorhexidine twice daily for 15 days, without the need for antibiotics. Final considerations: Low immunity due to the systemic involvement generated by Chikungunya was essential for the appearance of necrotizing gingivitis. Follow-up was carried out for almost a month, where the patient's periodontal health was reestablished.
