Interim report of the ad hoc committee for the consideration of statistical concerns related to the use of intra-oral models in submissions for product claims approval to the American Dental Association.
Subsequent to the American Dental Association Symposium on Intra-oral Studies, held in Chicago in September, 1990, the Council on Dental Therapeutics decided that further consideration should be given to statistical issues relating to intra-oral models. The authors accepted the request of Council staff to assist in the development of Guidelines concerning the validity, reliability, and combinability of data obtained from these models. The ensuing work in this area, which began in the fall of 1990 and has continued to date, has thus far focused on the tissue of validity. The purpose of the present paper is to provide the interested community at large with an update on the progress made thus far, and to provide some perspective as to where all of the work in this area may eventually be leading. It is anticipated that a more comprehensive and definitive report will be produced at the completion of this process.
