I do n o t find th a t credit has been given to the dentist and dental organization for creating such a program 21 years ago. In 1967, Frank M.

As far as I know, th is is th e firs t e x a m p le of r e q u ir e d c o n tin u in g office au d it in the US health p ro fe s sio n s. In 1974, S C SO M S ad d e d the phrase “ self-regulation in the public interest” to its official logo.

Performance time and gloves □ T h e article, “ G loved an d ungloved: perform ance tim e for tw o dental proce dures” by Dr. H ardison an d others (May), in d ic a te d th a t g lo v in g a n d re m o v in g gloves increased tim e for each procedure by a n a v e rag e o f o n ly 28.7 se co n d s. A c c o rd in g to T a b le 1, th e p ro c e d u re percentage tim e, how ever, increased by 30%. If th is h eld tru e th r o u g h o u t th e dental office procedures, then either the provider m ust raise fees 30% or p roduction w ill be 30% less. . . .

TMJ testing □ In recent years, the dental profession in g e n e ra l a n d th e A m e ric a n D e n ta l A sso c ia tio n in p a r tic u la r h av e been d eluged w ith p ro d u cts c la im in g to be “ d ia g n o stic in stru m e n ts ” for te m p o ro m andibular (TM ) disorders. T h e a p p a ll ing lack of adequate scientific research has lead to sk e p tic ism , cy n icism , a n d a large credibility g ap in this field.
. . . In re sp o n s e to th e 1982 ADA president’s conference on T M disorders, I in it ia t e d a n d d ire c te d an o n g o in g re se a rc h p r o g ra m a t P a in R e so u rc e C enter, D u rh am , N C, to learn ho w to d ev elo p an a c c u ra te a n d re lia b le p sy ch o m etric assessm ent to o l for T M d is orders. “ Psychom etric testing” is a phrase th at the dental profession w ill be hearin g m o re in th e n e a r fu tu re . In g e n e ra l, psychom etric testin g refers to the m ea surem ent of m ental traits, abilities, an d processes. In practice, it has evolved in to a scien tific d isc ip lin e often focused on assessment of clinical param eters th ro u g h se lf-re p o rt sy m p to m in v e n to rie s. P sy chom etric testing has a 100-year history in the field of psychology and in recent years has made a significant co n trib u tio n to th e m ed ical p ro fessio n . T h e d e n ta l p ro fessio n has n o t yet felt th e im p a c t of this pow erful form of clinical assess ment. . . . T h e stra te g y w e u sed w as to a d o p t w ell-a cc ep te d th e o rie s a n d te c h n iq u e s of test d ev e lo p m e n t used in th e fields of psychology and behavioral an d social sciences an d rig o ro u s ly ap p ly th em to th e p ro b le m s of T M d iso rd e rs. We u n d e rto o k a m u ltis ta g e a n d m u ltis ite 5-year research program w hich involved the co llaboration of 30 clinicians in 19 states and C anada, studying alm ost 3,000 subjects.

T h is w ill require the establishm ent of technical standards for test dev elo p m en t as well as ethical standards and guidelines for use of such tests. . . . W hen the dentist is confronted w ith e v a lu a tin g an y p sy c h o m etric tests, the follow ing questions should be asked: 1. Was test developm ent accom plished in ap p ro p riate dental p atien t p o p u la tio n s an d tested o n large en o u g h samples? 2. Was test construction based on wellac c e p te d a n d v a lid a te d th e o rie s a n d techniques? 3. H ave ad equate statistical a n d clin ical studies of the various types of validity (accuracy) an d reliability (consistency) been conducted? 4.
