A study has been made of the efficacy of several commercial mouthwashes representing as many classes of chemical agents. T h e method employed tends to represent, as closely as possible, the conditions of use. The selective antibacterial activity of the washes was measured in terms of "before" and "after" total bacterial counts, and the incidence of streptococci, staphylococci, fusoform bacteria, and lactobacilli. There is included a study of the length of time that elapses after the use of the mouthwashes before the number of bacteria in the oral cavity reaches the number resent before washing. Data obtained from these studies indicate that each of $e compounds significantly reduces the total bacterial count i n the mouth, and that some deal selectively with microorganisms. Each mouthwash, however, leaves residues of active bacteria among those removed from the oral cavity by a rinse technique. It appears also that the effect of the compounds is of short duration.
HIS COMMUNICATION continues the report of Tthe investigation that has been in progress for the purpose of developing specific in wi wo bacteriological methods for the evaluation of mouthwashes (1,2).
