Experimental palatal candidosis and saliva flow in monkeys.

Abstract

Maxillary acrylic plates, inoculated with Candida albicans, were inserted for 3 weeks in 10 monkeys (Cercopithecus aethiops) (Series I), and reinserted in five of the animals 8 weeks after removal (Series II). To suppress saliva flow oxyphencyclimine was injected intramuscularly (0.125 mg/kg) thrice daily for 3 weeks in six monkeys of Series I, while four controls received no drug. In Series II the oxyphencyclimine dose was doubled in three animals, and two controls were sham-treated with sodium chloride. Mean saliva flow was reduced to 58% after 1 week and to 63% after 3 weeks with the low dose of oxyphencyclimine. The values with the high dose were 56% and 64%, respectively. After 1 week thrush had developed beneath the plates of all monkeys. The patches were more extensive and regressed slower with oxyphencyclimine. Enlarged lesions were seen with the double dose. In Series I intraepithelial invasion by hyphae was detected more frequently and longer after inoculation in the oxyphencyclimine group. Such invasion was not found in biopsies from Series II. It is likely that saliva offers some protection against yeasts colonizing the fitting size of a denture.
