[Investigations on dentin metabolic processes in the teeth of dogs via tetracycline fluorescence].
The third incisor and canine of the lower jaw of 2 dogs were sterilely pulpectomized in order to study the dental pulp metabolic processes. At the same time, at different intervals, prior to and post pulpectomy of the teeth, tetracycline was injected--30 mg per 1 kg body weight. The results from the investigations established uneven, interrupted fluorescence in part of the dentinal canals and fluorescent strips in the nonpulpectomized teeth, where tetracycline was included in the newly formed dentin. Fluorescent strips were not formed in the pulpectomized teeth, but an interrupted and uneven fluorescence was established in part of the dentinal canals, very likely, due to tetracycline, penetrating from peridentium, via diffusion, through the cement into the dentinal canals.
