RESUMO
Myiasis, a term first introduced by Hope (1840), refers to the invasion of tissues and organs of animals and human wounds and certain body cavities by the dipteran larvae which manifests as subcutaneous furunculoid or boillike lesions. Oral myiasis is a rare pathology and a risk to the patient's life. Higher incidence is seen in rural areas affecting the tropical and sub-tropical zones of Africa and America. Myiasis affecting the oro-dental complex is rare. Here is a case report of oral myiasis in an 18-year-old male patient who is mentally challenged with anterior open bite, incompetent lips, and periodontal disease. The lesion was treated with turpentine oil, which forced larvae out and irrigated with normal saline solution. Follow-up examination revealed complete remission and healing of the lesion.

Human myiasis is characterized by larval infestation of body tissues or cavities of live individuals. Although most frequently observed in underdeveloped and tropical countries, reports of human myiasis have been encountered throughout the world. Conventional treatment is the mechanical removal of the larvae, one by one, which is painful and embarrassing and repugnant to both health professional and patient. Even though human myiasis is not considered rare, most dental professionals have very little knowledge of the diagnosis and treatment of this pathology. The purpose of this article, therefore, is to report a case of advanced-stage oral myiasis in a 9-year-old patient treated at a health and dentistry clinic. Diagnosis was based on visual observation of Cochliomyia hominivorax larvae, a dipterous fly of the Calliphoridae family, which were between the second and third stages of development. Predisposition factors include lack of information, malnutrition, poor oral hygiene, preexistence of oral lesions, and severe halitosis, which decisively influence the appearance and development of oral myiasis. A brief review of the literature is also included, in which the importance of early clinical diagnosis, myiasis etiology, and possible associations with other pathologies and different types of treatment are discussed.
