Dental plaque reduction with an antibacterial mouth rinse. Part I

Abstract Two groups of fifty young male subjects rinsed their mouths once daily for 5 days with 15 ml. of a prescribed liquid mouthwash. Group I received a placebo and Group II received a new antibacterial agent, 0.035 per cent Alexidine with 18 per cent alcohol. Plaque scores were recorded for pretreatment and posttreatment examinations, and their incremental difference was tested for significance. The treatment groups improvement was statistically significant. There was no statistical difference in plaque reductions between those teeth receiving a prophylaxis and those left with preformed plaque. Carry-over effect after cessation of treatment was not significant.

Evaluation of a simplified caries index for use by the US Army Dental Corps.

The evaluation of a simplified caries index was undertaken to determine the validity and reliability of the index when applied to a military population. Although certain internal assumptions of this simplified caries index were not upheld, the index did rank order the populations by severity of caries experience when compared to the DMFS index. High interexaminer and intraexaminer reliability scores were demonstrated.
