CorelationBetween The Masticatory Efficiency And Type Of Mastication
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 10
Abstract
Aim:To evaluate the influence of the type of mastication (temporal and masseteric) on the functional state of the masticatory system. Material and method:The examinations were conducted at the Institute of Medical and Experimental Physiology, Faculty of Medicine in Skopje. The study included 96 respondents (35 males and 63 females). The type of mastication is determined by examining the biopotentials of the masseter and temporal muscles of the subjects. Subsequently, their masticatory efficiency with determined using a specially constructed instrument, ELECTROMASTICIOGRAPH, which graphically processes and records the mandibulemovements and the chewing muscles during the masticatory act. The mechanical efficacy is determined by the number of chewing cycles and the time of mastication. Walnuts with a precise weight of 2.5 grams were used as a test-food. Results:The obtained results from this study showed that subjects with masseteric type of mastication, peformed the mechanical crushing of the food in 3.64 milliseconds and during 2 chewing cycles. Also, these subjects performtheir grinding phase of the food in a period of 2.55 milliseconds and 3 chewable cycles. On the other hand, subjects with temporal type of mastication, perform the mechanical crushing phase in 6.16 milliseconds and during 3 chewing cycles.These subjects performed their grinding phase in a period of 4.06 milliseconds and 2.31 chewing cycles. Their correlation was calculated by linear regression coefficients. Conclusions:The results that were gained in this study showed significant differences in the masticatory efficiency of both examined groups. In fact, the speed of the masticatory act is greater in subjects with masseteric type compared to those with temporal type of mastication.
