The Ammonia Content of the Mouth

Abstract
The total ammonia of the mouth, and that which can be removed by tooth brushing was detd. The procedures were performed on caries active and caries inactive mouths and the results were compared. The ammonia that could be removed by brushing was detd. by brushing the teeth, using permutit as the dentifrice, after which the brushings were analyzed by the usual Nessler procedure. For the total ammonia, the debris removed by means of a dental prophylaxis was added to the tooth brushings after which the usual analysis was repeated. There was no significant difference between the ammonia content of caries active and caries inactive mouths. The amt. of ammonia that could be removed from any one mouth was quite constant, but varied from individual to individual and averaged 80% of the total.
