Clinical training of dental interns will be required by law, starting in 2006. In view of this Matsumoto Dental University set up the Department of Interdisciplinary Dentistry in 2001. In this department, one-year training of clinical interns is given, and as a curriculum for clinical interns in intra-oral radiography, the interns' mutual practice is performed, so that interns can reconfirm the techniques and prepare themselves for performing this radiography in patients. We recently conduted a technical evaluation of the intra-oral radiography performed by clinical interns in 2001 and 2002, the results of which were as follows: 1. In intra-oral radiography, individual interns' degree of success was 89% at the highest and 29% at the lowest, with an average of 58%. 2. The degree of success by region in the upper jaw was in the order of the anterior teeth region, the canine site, bicuspid site, and the molar region. In the lower jaw, the degree of success was in the order of the anterior teeth region, the canine site, the bicuspid site, and the molar region. 3. Failure by region in radiography was due to poor vertical angle, poor positioning of X-ray film, corncut, and poor horizontal angle. 4. In the analysis of causes of failure in radiography at the molar region in the upper and lower jaws, many cases of poor positioning of film and poor vertical angle were observed in the upper jaw. In the molar region of the lower jaw, many cases of poor positioning of film and corncut were noted. From the above, it is considered necessary hereafter to train interns, before they perform radiography, regarding the correct techniques of radiography, using such aids as phantoms, models of the jaw, and videos ofintra oral-radiography actually being performed. |
