Resumo
Os efeitos provocados pela retirada cirúrgica das glândulas salivares maiores sobre a placa bacteriana e doença periodontal foram estudados em ratos albinos Wistar. Após a sialoadenectomia houve diminuição da placa bacteriana nos dentes incisivos, o que não ocorreu nos molares. Não se observaram alterações na evolução da doença periodontal provocada pela colocação de irritante gengival na cervical dos primeiros molares inferiores nos animais sialoadenectomizados.

Abstract
The effects of the surgical removal of the major salivary glands on the dental plaque and periodontal disease were studied in Wistar rats. The provoked xerostomia decreased the amount dental plaque on the incisors, but plaque was unchanged on the molar teeth. Periodontal disease and bone loss provoked by a cotton ligature placed around the cervical area of the first lower molar were similar in normal and sialoadenectomized rats.
