Resumo

A ulceração aftosa recorrente (UAR) oral é uma condição caracterizada pelo desenvolvimento periódico de úlceras solitárias ou múltiplas e dolorosas na mucosa oral, de etiologia ainda não muito bem esclarecida e bastante incômoda para o paciente. Entre os fatores predisponentes propostos estão estresse, história familiar, trauma, hipersensibilidade alimentar, deficiências nutricionais, alterações hematológicas e, ainda, um possível envolvimento bacteriano. Porém, a etiologia é ainda controversa, sendo mais aceito o mecanismo imunológico, especialmente a citotoxicidade mediada por células. Como numerosos fatores têm sido propostos, torna-se difícil estabelecer um protocolo terapêutico eficaz para todos os casos. Tanto a etiologia quanto o tratamento parecem ser particulares para determinados pacientes. O entendimento dessa condição é importante para o cirurgião-dentista, pois ela dificulta a alimentação em muitos casos, interferindo na qualidade de vida dos pacientes por ela acometidos.

Abstract

Recurrent aphthous ulceration (RAU) is a condition characterized by periodic development of painful, single or multiple ulcerations of the oral mucosa. The principal cause has not been discovered. The main aetiologic factors are stress, heredity, local trauma, food hypersensitivity, immunological mechanisms, alimentary deficiencies, haematological abnormalitys, and bacterial infections. Like various aetilogic factors are possible, it´s difficult to establish a efficient therapeutic protocol for all cases. It seems that the aetiology and the treatment are particular for each case. It´s important for the dentist to understand this condition, because it´s very bothering for the patient, making it difficult its feeding, influencing in its quality of life.
