Variability between credit units dedicated to dental and clinical sciences in dental schools across the USA.

PURPOSE: The Commission of Dental Accreditation (CODA) does not set minimum standards for clock hours of training in Dental and Clinical sciences. The purpose of this evaluation was to compare United States (US) dental schools for variability in clock hours. The current paper utilizes the American Dental Association's survey of clock hours of all US dental schools which is publicly available data. Clock hours survey from 2010 to 2011 was utilized and the analysis tool, JMP, was utilized to visualize and report variability.

PERSPECTIVE: The current paper highlights the large variation in clock hours of training among core clinical subjects in accredited dental schools around the United States. For example, teaching Physical Evaluations; Oral and Maxillofacial; and Oral Diagnosis and Treatment Planning were 97.0; 126.6; and 74.4 h. Moreover, upper limit for hours of Operative Dentistry teaching was 1410 h and lower limit was 129 h. Various other fields of education do enforce strict requirements on educational clock hours. For instance, Massachusetts' General Law states that both private and public schools must have 900 and 990 h in a school year for elementary and secondary schools, respectively. However, no such stipulation exists in the field of Dental Education. CODA's mission is "to serve the oral health care needs of the public" and CODA must consider if the average dental patient would consider a dentist who attended the school delivering 1410 h of Operative Dentistry to be the same standard as a graduate of the school delivering 129 h.
