In recent years an increasing incidence of malocclusion and temporomandibular joint disorders in younger age groups has developed into a problem. It is therefore important for growth and normal deelopment to evaluate occlusal force to keep normal function of occlusion. In the present study, we investigated the fundamental requirements of an occlusal diagnostic system which consisted of pressure sensitive sheets (DENTAL PRESCALE®) and an analyzing computer (OCCLUZER FPD 703®before we use this system on infants.
The results were as follows:
1. The optimun custody was in a refrigerator, and next was packing in light resistant material at normal temperature.
2. Storage in a refrigerator diminished influences on artifact values for prolonged periods.
3. Storage under fluorescent light or in direct sunlight over time tended to decrease the coloring area and pressure values. DENTAL PRESCALE 50 R was affected by light more than 30 R. It necessary Thus to shield the DENTAL PRESCALE from light immediately after sampling.
4. Measurements after storage in a refrigerator should be performed for 30 R between 3 hours and 1week, and for 50 R between 3 hours and up to 3 days after sampling.
5. The average values for the measurements of coloring areas and pressure values showed a larger tendency than theoretical values. The increasing rates of the coloring area were larger as the load increased, while one of the maximum pressure values conversely tended to become smaller both 50R and 30 R.
