Effect of Chromates on the Teeth

Author and Disclosure Information

Abstract

A DENTAL survey was made on 100 men employed in the chromate division of Diamond Alkali Company and the observations were compared with a similar number of Cleveland Clinic patients. The age range was comparable, the largest number of chromate workers falling in the 26 to 40 year old bracket, while the clinic group had the largest number in the 41 to 60 age group. The chromate group had no general complaints, while the patients in the clinic group had some systemic or oral disorder for which the dental inspection was requested.

In the chromate group, 79 reported or displayed evidence of irregular dental care. Such care had consisted primarily of extractions, as noted in the large number of missing teeth. Irregular professional care was noted in 55 of the 100 clinic patients.

In evaluating dental sepsis, x-ray evidence was a prime consideration. Teeth which showed periapical tissue change or excessive alveolar resorption extending beyond the middle half of the root of the tooth were classed as septic, and beyond conservative care.

In the chromate group a total of 30 (30 per cent) showed chronic dental sepsis, 17 per cent of which were diagnosed as chronic alveolar abscess; 10 per cent had severe periodontoclasia and 3 per cent displayed evidence of both conditions. Seventy per cent showed no definite chronic sepsis.

In the clinic group 58 per cent manifested conclusive indications of chronic dental focal infection. This might again be subdivided into 20 per cent with chronic alveolar abscess, 21. . .
