초록

This study analyzes through the review of literature and laws the exposure time, clinical frequency,
and radiation exposure of intraoral and extraoral radiography as well as of panoramic radiography
performed by dental hygienists in dental clinics, compares the dental radiology curriculums of
radiological science and dental hygiene departments, and proposes the expansion of dental hygienists'
radiography operations.
The radiology curriculums were compared between the radiological science and dental hygiene
departments of colleges. For new analysis by radiography for dental diagnosis, the exposure time,
radiation absorbed dose, effective dose, and number of days of natural radiation were compared by
the type of oral radiation films and radiographical techniques proposed by domestic and international
studies.
The exposure time of panoramic radiography is 15 seconds and it takes about two minutes for completion,
whereas the exposure time of the standard radiography is 0.2 ~ 0.8 seconds and it takes 10
times longer for completion of the radiography of full mouth than the panoramic radiography. The
standard radiography can cause distortions of radiation at severely curved parts of dental arch and
palatopharyngeal reflex. However, panoramic radiography can be performed even for lock jaw patients, causes less inconvenience to patients and is much simpler than the standard radiography.
The percentage of dental clinics where radiography is performed by dental hygienists was 92.0%, and
the percentage of standard film radiography by dental hygienists was 98% whereas the percentage of
panoramic radiography by dental hygienists was 92%. For the absorbed dose which is an indicator of
radiation exposure, the When the effective dose which is an indicator of the danger of radiation
exposure was converted to the number of days of natural radiation, it was 3.3 days for panoramic
radiography, but 13.9 days for the full mouth standard radiography by bisecting angle technique
which was 4.2 times longer than the panoramic radiography. There were two colleges that had a dental
radiology course with two credits in the departments of radiological science. The credits for dental
radiology courses in the department of dental hygiene ranged varied by college, ranging from 3 to 8;
on average, the theory course was 2.2 credits and the practice course was 2.02 credits.
To summarize the above results, the percentage of dental clinics where panoramic radiography is
performed by dental hygienists under the guidance of dentists is high. Panoramic radiography has
become an essential facility for dental clinics. It is faster than standard film radiography and less
dangerous due to low radiation exposure. Panoramic radiography is a simple mechanical job that
does not require training of oral radiography by radiotechnologist. Because panoramic radiography
is one of major operations which must be performed at all times in dental clinics, it must be designated
as intraoral technique rather than extraoral technique, or legalized for inclusion in the scope of
operations of dental hygienists.
