Abstract：In recent years, the use of dental magnifying glass has been spreading for the accurate diagnosis and treatments. In this research, we decided to introduce a dental magnifying glass during a practical training course at a training school and to verify its usefulness.
The subjects were 52 2nd year students enrolled in a prefectural school in 2015 and 51 2nd year students enrolled in fiscal year 2016, totaling 103 people.
In both 2015 and 2016-from April to November, we introduced a magnifying glass for jaw model practice and mutual practice of the dental preventive treatment subjects. The subjects were asked to detect and remove the artificial dental calculus (protrusions) in phantom head, jaw and teeth models with and without the dental magnifying glass as a practical test. The use effect of dental magnifying glass was evaluated by the total numbers of detected and removed protrusions. After the test, a questionnaire was also conducted to the subjects to subjectively evaluate the use effect of dental magnifying glass.
Both detection and removal numbers with the dental magnifying glass were significantly higher than those without the dental magnifying glass. The result of questionnaire showed a positive attitude toward the use of dental magnifying glass.
By using a magnifying glass in a practical training in a training school, it improved the ability to detect protrusions corresponding to dental calculus, you can gain many benefits such as improving motivation for future hygienist work, it was suggested that its introduction is useful for practical training.
