ABSTRACT
To highlight the effect of 1,1,1,2 tetrafluoroethane (TFE), a new material for cryosurgery of gingival melanin pigmentation (GMP). Five patients were treated using a TFE-cooled swab and the pre- and post-treatment photographs were compared. Complete keratinization took place in 3-4 weeks after application without any trace of pigmentation. During the follow-up period, no side effects were observed and the improved esthetics were maintained upto 1 year.

Figure 8: Pre and post-operative photographs of Case 2

Mentions: Before application of TFE, the pigmented area was isolated and air dried Immediately after spraying, the temperature of the cotton applicator ranged from −46.7°C to −48°C.[4] Topical anesthesia with 2% lignocaine spray (lignocaine hydrochloride and adrenaline bitartarate injection, 2% with adrenaline 1 in 80,000, ICPA Health Products Ltd, 233A, Adarsh Indl. Estate, Sahar Road, Chakala, Andheri (East), Mumbai - 400 099, Maharashtra, India) was used to minimize discomfort [Figures 1 and 2]. TFE (134a, refrigerant for AC systems, contains 1.1.1.2-Tetrafluoroethane, DUPONT SUVA, DUPONT Fluorochemicals, Louisville Packaging Site, 7745, National Turnpike, Suite 190, Louisville, KY, USA 40214) was sprayed on a cotton swab and immediately rolled gently over the pigmented area and a freezing zone was continuously maintained in each area for about 30-40 s [Figures 3 and 4]. After the cryosurgical procedure, patients were examined at 1, 2, and 4 weeks [Figures 5 and 6] and subsequently after 1 year [Figure 7]. Digital photographs of the pigmented area were taken preoperatively and at each subsequent postoperative visit. [Figures 7 and 8]
