In order to observe the rate of error to intraoral standard radiographic techniques, this study analyzed 560 films, and conducted a questionnaire with 20 Dong Pusan College students who have used the bisecting angle technique.
Followed are the results of the student.
1. In maxillar, the rate of error was the highest for incorrect film placement and overlap. The most of error rates were identified in cuspid before clinical practice and in premolar after practice.
2. In mandible, the rate of error was the highest for incorrect film placement and elongation. The most of error rates were identified in premolar before clinical practice and in incisor after practice.
3. Clinical practices for standard radiographic techniques improved error rates from 31.5% to 17.9% in maxillar, from 26.0% to 19.3% in mandible.
4. The result of survey with students was that the error of radiography was the most in maxillary cuspid and that vertical angulation was the most difficult.
