| case report Gingival depigmentation using diode laser A non-ablative technique with test patch Dr Chayanee Prakongsantikul & Assoc. Prof. Dr Sajee Sattayut, Thailand Gingival hyperpigmentation is a condition affecting aesthetic appearance. There are many techniques for treating gingival hyperpigmentation, but still no tech- nique available for patients to select a satisfactory gin- gival colour. In this case report, we present a technique of gingival depigmentation using a diode laser that pro- vides a test patch for the patient to decide on the gin- gival colour. Introduction Nowadays, people are increasingly concerned about aesthetics. The appearance of the smile is affected by not only the teeth but also the gingivae. Much of gingival hyperpigmentation is due to normal physiological varia- tion rather than being pathological in nature. In this case report, although it did not present any medical problems, Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 1: A melanotic macule of the lower lip. Fig. 2: Pre-op hyperpigmentation of the gingiva of the maxillary anterior teeth. Fig. 3: Test patches as indicated by A and B. The blue arrow is pointed to an incisional biopsy area. Fig. 4: Two weeks after laser dose testing and incisional biopsy, complete healing of the gingiva was observed. The patient was able to detect the difference in colour between the areas treated with Settings A and B. 08 1 2018
