[Acute caries model in albino rats].

Abstract

The author used high-saccharose fine-powdered diet of Stephan 580 for the reproduction of acute caries model as well as 6-week experimental period for 50 "Wistar" 21-days old rats, distributed into two groups--experimental and control. The carious lesions were established by a modified index, guaranteeing a complex evaluation of the lesions developing upon the fissurae, approximal and smooth tubercular surfaces. A high caries index was established. The involvement of the main transversal fissurase and of the contact approximal surfaces of rat molars in the upper and lower jaws was separately established.
