The necessary personal oral hygiene for prevention of caries and periodontoclasia.

Almost all loss of teeth results from either caries or periodontoclasia. These two diseases can be prevented by the necessary personal oral hygiene. They cannot be prevented in any other way now known. The purpose of this paper is to present the oral hygiene procedure every person must follow in order to entirely prevent these diseases and their consequences, and in order to maintain the state of oral cleanliness most people would like to maintain. The personal oral hygiene procedure here presented as essential has evolved from practical application of already well known fundamental information and more recent additional pertinent information that has been published or is in process of publication (1-4). By intensive microscopic study of extracted teeth, employing technical procedures (1,2,5) not usually employed for this purpose, it has been possible to secure more accurate information regarding the conditions at the locations and in the environment where caries and periodontoclasia begin.
