Testing of fine motor skills in dental students.

Manual skills form only a part of the capabilities required of future dentists, but they are a very important component, which should be tested. With regard to the dental specialties, the present study tested specialty-independent fine motor skills. No objective, practical solution has been found up to now. 88 dental students and, as a control group, 23 medical students were examined in the longitudinal study. In the course of the analysis, 4 fine motor tests were carried out at the beginning of the 2nd and 6th semesters. The tests comprised the tremometer test, the tremometer test with a mirror, the 2-hand sinusoid test and archery using the Game Gear by SEGA. The test devices facilitate primarily the testing of components of accuracy of movements, indirect working methods, and eye-hand coordination. In the comparison of performances on test day A, the medical students' performance was noticeably better. As testing progressed, results showed stagnation in the performance of the medical students and a significant improvement in the performance of the dental students. That means that the test system can be used for a test over the course of study, but not as an initial test.

Aptitude Tests↗

[Occupational medical and orthopedic aspects of the dental workplace].

On the basis of traditionally designed dental workplaces recognized occupational diseases of dentists are presented. Clinical examples indicate the focuses of orthopaedic diseases. By means of improved technical health equipments such working conditions can be designed representing an essential precondition for a load-reduced work. Objectifications of posture parameters are brought in to make optimized use of the equipment and materials base.

[Sediments on the inner surfaces of the tube of spray-mist suction devices].

Spray mist suction tubes made of polyvinylchloride were examined. Qualitative and quantitative germ determinations of the tube inner surfaces were carried out. To make reproducible examinations a standardized method of germ determination was introduces. Macroscopical model tests, assessments by scanning electron microscopy and chemical analyses dealt with the genesis of the deposits and bacterial coatings in the inner tube. A method has been found which minimizes coating formation by spraying of a contaminating cleaning agent.

[The spread of the backspray under different working conditions].

The use of high- and highest-speed preparation instruments and the therefore required intensive spray cooling results not only in more efficient working possibilities but also in an increased infection hazard, especially for the dentist and his assistance caused by the spray rebound. Simulated preparations were carried out on different tooth surfaces at different positions of the patient with or without exhaust under clinical conditions to objectify the space spreading of the spray rebound. The arrangement of the equipment has been objectified by photogrammetry so that the measurement data could be clearly classified. The use of the spraying mist exhaust reduces the spray rebound between 50 and 65%.

[The long-term effects of noise on dentists].

On the basis of analyses of the main noise emitting equipment was carried out an audiometric test of dentists. The high frequencies of various equipment are reflected in a reduced high-frequency hearing. Significant differences became evident with increasing years of service, as well as in comparison to age adequate control groups. The high-frequency audiogram used in addition to the normal threshold audiogram is suitable to prove such occupational changes. The measured hearing loss remained without social importance in all cases.

[Hearing protection against noise in the stomatologic clinic].

On the basis of current analyses of the noise situation in the stomatologic practice proposals are made for noise control. An newly developed personal ear protector is especially taken into consideration. Furthermore, the possibility of using wide-band absorbers is presented to reduce the room sound level.

[Investigations of stomatologic lighting equipment].

12 types of stomatologic lighting equipment were investigated with regard to their specific luminous intensity. The examination of the thermal radiation of the lighting equipment included subjective evaluations. Conclusions were drawn in order to improve the lighting.
