Title Changes in the buccal cavity in workers exposed to cadmium compounds
Original title Otnosno săstojanieto na ustnata kuhina u rabotešti v kontakt s kadmievi săedinenija [in Bulgarian]
Bibliographic information June 1971, Vol.18, p.267-271. 10 ref.
Abstract Symptoms found in certain structures of the buccal cavity are of great importance in the diagnosis of cadmium poisoning, in particular a golden yellow colouring of the teeth due to cadmium sulfide, and the cadmium line at the base of the incisors, which is considered a decisive early symptom. The author examined 47 workers (31 men and 16 women) employed in the cadmium department of a Bulgarian non-ferrous metals plant, aged 18-55 years (with up to 12 years' exposure). In most cases, the pathological processes were not specific either clinically or morphologically. Their great prevalence and their simultaneous appearance with other paraclinical divergencies confirmed the influence exerted by the toxic substance. The yellow cadmium line at the base of the teeth occurs on exposure to even small concentrations of cadmium at the workplace. For specific diagnosis, it is necessary to use hystochemical methods for detecting tissue cadmium.
