• Clinical Evaluation of The Bite Force Measuring System Utilizing “Dental Prescale”

抄録

Previous studies have shown that the bite force of children can be measured using a pressure-sensitive sheet known as “Dental Prescale” (Fuji Photo Film Co. ). A common method for measuring the bite force using “Dental Prescale” has however not yet been established.<BR>The first aim of this study was to compare the accuracy of two types of pressure-sensitive sheets, “Dental Prescale 30 H” and “Dental Prescale 50 H” (Fuji Photo Film Co. ). Twelve children with normal occlusions; 8 boys and 4 girls (avg.8.4 years) were selected. The maximum bite force was recorded by using “Dental Prescale 30 H, type R (pressure measurement range,3-13 MPa)” and “Dental Prescale 50 H, type R (5-120 MPa)”. The proportion of bite tests from the subjects which fell within the pressure measurement range of the two types of “Dental Prescale” was 82.4% for 30 H, and 98.1% for 50 H. “Dental Prescale 50 H” should therefore be used for measuring the bite force of children because 30 H could not measure the 17.6% of the bite force test results which were greater than its maximum pressure measurement level.<BR>The second aim of this study was to determine the best length of time that clenching should be maintained when measuring maximum clenching in children using “Dental Prescale”. Sixteen children with normal occlusions; 8 boys and 8 girls (avg.9.3 years) were selected. The maximum bite force which was exerted 0 sec.,1 sec.,2 sec. and 3 sec. after maximum clenching was achieved was recorded using “Dental Prescale 50 H”.<BR>The results showed that the longer that clenching was maintained, the larger the maximum bite force tended to be. The maximum bite force, however, was nearly the same for 2 sec. and 3 sec. furthermore, the variation coefficient at 0 sec. was larger than for 1 sec.,2 sec. and 3 sec.. It is therefore reasonable to suggest that the length of time for which maximum clenching should be measured is 2sec. or 3 sec.
