The purpose of this study was to examine the correlation between crushing energy and absorption in the measurement of masticatory efficiency. The spectrophotometric method using ATPG (Adenosine Triphosphate Granules) developed by Masuda et al.was utilized. A new method of evaluating masticatory performance is proposed.<BR>This study measured absorption of ATP-G at:(1) precrush levels, (2) after the performance of 50 masticatory strokes by 50 adults (30 men and 20 women) with normal occlusion and (3) post crush with known energies by use of a stamp mill. The following results were obtained:<BR>1) Crushing energy was in proportion to absorption.<BR>2) Mean absorption levels were 1.25 Abs in men and 0.98 Abs in women.<BR>3) The absorption level after 50 times falling crush with the stamp mill was similar to these results. The falling weight was 6.0 kg. The falling height was 2.0 cm.<BR>4) Under these conditions, the correlation between the number of falling crush times by use of the stamp mill (x) and the absorption level (y) was indicated as: y=0.022x+0.07 (r = 0.997)<BR>5) Utilizing this equation, the absorption level measurement allowed us to determine the number of falling crush times that correlated to the masticatory performance of the subject. One falling crush produces 1.18 Joules of energy. Therefore, by multipling the number of falling crush times by 1.18 (J), the masticatory performance of the subject can be quantified.<BR>6) Quantitative evaluation of masticatory performance, utilizing absorption level, was also made by comparison to a "Standard masticatory performance" equal to 1 SMP (Stamp Mill Power). This standard value correlated to an absorption level after 50 times of falling crush with the stamp mill.
