ABSTRACT
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.

Estudou-se o potencial irritativo de um cimento à base de antibiótico quando em contato com o tecido conjuntivo subcutâneo de rato comparando-o com o cimento de óxido de zinco e eugenol (ZOE-Grupo Controle). Para isso, foram implantados no tecido subcutâneo dorsal de 25 ratos tubos de polietileno preenchidos com os materiais em teste. Decorridos os períodos de 3, 7, 15, 30 e 60 dias, foram feitas as biópsias dos implantes, cujos cortes histológicos revelaram a presença de reaçäo inflamatória com predomínio de células mononucleares sempre inferior em relaçäo ao cimento de antibióticos, sendo que essa reaçäo descreveu com o decorrer dos períodos, chegando aos 60 dias a formar uma cápsula fibrosa densa que apresentava continuidade com aquela formada junto à superfície lateral do tubo. Concluiu-se, através de análise subjetiva dos cortes histológicos, que o cimento de antibióticos foi menos irritante ao tecido conjutivo do que o cimento de ZOE
