Abstract
Occlusal force has the main role in determining the teeth health in general and determining the chewing, muscle and TMJ function. The objective of this study was to find if there was any relation between the preferred chewing side and the force, measured by T-scan III system. The total number of 90 (46 female and 44 male) dental students was included in this study. They were asked whether their preferred chewing side was right, left or both. Afterwards, the occlusal forces in habitual occlusion, using T-Scan III Electronic device (IP-CO position mode, MA-mode, MA sensitivity setting) were measured. The data were presented as Mean ± SD. Spearman correlation was used to find the correlation between the occlusal force and chewing side. Differences in P 0.05) and the right side (r = 0.143, P > 0.05) according to the preferred chewing side. In this study, the relation between the preferred chewing side and occlusal force was found.
Highlights
Maximum bite force is one of the indicators of the functional state of the masticator system [1]-[3]
Masticator function is predicted by a number of parameters, including bite force [6] and occlusal contact area [7], which suggests that the higher the bite force is and the larger the occlusal contact area is, the more efficient the mastication is
There was no statistical significance of occlusal force according to the quadrants: anterior left, anterior right, posterior left and posterior right (P > 0.05) (Table 1)
Summary
Maximum bite force is one of the indicators of the functional state of the masticator system [1]-[3]. The force results from the action of the jaw elevator muscles (in turn, determined by the central nervous system and feedback from muscle spindles, mechanoreceptors, and nociceptors) modified by the craniomandibular biomechanics [4]. It is considered that the bite force is the key determinant of the masticator function [5]. Reduced masticator function is related to smaller occlusal contact area [7]. Lower activity of the cervical muscles has been associated with a smaller occlusal contact area [8]. Maximum bite force is a useful indicator of the functional state of the masticator system and the loading of the teeth, and its recordings can be performed in a relatively simple way in the clinic
