| 内容記述 | Various electric contra-angle handpiece apparatuses for root canal filing have been clinically applied to root canal enlargement and preparation. By using Try-auto (TR-ZX, Morita Corp.) with a cordless handpiece incorporating an electric root canal length measurement apparatus, root canal enlargement and preparation can be performed utilizing the properties of nickel titanium files. In this study, 3 clinicians with different clinical experience (2, 8, and 18 years) performed root canal enlargement and preparation of the extracted human lower incisors using TR-ZX, and by manual method, and the time required for the root canal enlargement and preparation, degree of the reach of the instruments in the root canal, and root canal cleaning level, were evaluated by comparing the results by the use of TR-ZX and by the conventional manual method. The results obtained were as follows: 1. The clinician with 8 years' experience required shorter time to perform the root canal enlargement and preparation by manual method than by using TR-ZX, whereas the other clinicians showed no differences between the time required by manual method and that required by the use of TR-ZX. 2. With regard to the degree of the reach of the instruments, root canal enlargement was performed setting the measurements of the length up to the root apex indicated by the root canal length measurement apparatus incorporated in TR-ZX -0.5 mm as the working length, and the degree of the reach of guttapercha points inserted in the root canal was evaluated, setting the position of the anatomical apical foramen -0.5 mm as the reference point. Good results were obtained by both manual method and the use of TR-ZX, except in 1 tooth, in which poor results were obtained by manual method. By comparing the results based on the differences in clinical experience, clinicians with long clinical experience showed better results by manual method than by the use of TR-ZX, and the results were improved according to the increases in the experience period, whereas clinicians with short clinical experience showed better results by the use of TR-ZX. 3. With regard to root canal cleaning level, the root canal was observed classified into tooth crown side 1/3, middle area 1/3, and apical side 1/3, and the cleaning level was almost good in the tooth crown side area and middle area of the root canal, showing no differences in the level between by manual method and using TR-ZX, except in 2 middle areas, in which poor results were obtained by the use of TR-ZX. Concerning the cleaning level in the apical area, clinicians with long clinical experience showed better results by manual method than by the use of TR-ZX, and the results were improved according to the increases in the experience period, whereas clinicians with short clinical experience showed better results by the use of TR-ZX. | |||||||
