Abstract
Acrylic resins are widely used in dentistry, especially in orthodontics and prosthetics. Patients: this article reports the case of a leukodermic 33-year-old male who reported discomfort and pain due to an erythematous lesion in the first left premolar after the placement of an acrylic resin temporary restoration. Discussion: The signs and symptoms presented by the patient and his report of visiting the rural countryside generated concern regarding the possible diagnosis, which led to a more invasive biopsy to differentiate allergic inflammation from a paracococcidioid mycosisIncisional. Biopsy revealed a chronic inflammatory process. Conclusion: the pathology was caused by contact with methyl methacrylate-based provisional acrylic resin.

Summary
I n recent decades, many substitutes have been developed for methyl methacrylate acrylic resins in response to many reports of allergic reactions, chemical irritation, and a burning sensation in the mouth. We report a case of an allergic reaction to methyl methacrylate-based resin after the fabrication of a temporary crown. The patient reported that he had sought treatment two months previously because he broke a tooth and that the dentist had prepared the tooth and installed a provisional acrylic crown. He had not yet returned for delivery of a permanent crown, and two months ago, he experienced discomfort and erythematous, bleeding gingiva. The patient was referred to a dentist who continued treatment, and after cementation of the final crown, the inflammatory signs and symptoms disappeared. (figure 3)
