Testing therapeutic measures for controlling chronic gingivitis in man: a suggested protocol

C R Cowell et al. J Clin Periodontol. 1975.

Abstract

A protocol is presented for the clinical evaluation of agents used to control chronic gingivtis in man. Assessment is divided into three phases of increasing duration which are the initial screening of products over 1 month, the main gingivitis trial lasting at least 6 months and judging the effect of the product in preventing periodontitis which is extended for at least 3 years. The advances in data processing have made it possible to collect information separately on the three parameters of gingival inflammation.
