Introduction For language, the major imperative behavioral irregularity is hand- edness because of its close relationship with the brain specializa- tion. Handedness can be seen in 3 levels, i-e., right handedness, left handedness and both right and left handedness (mixed). The primary minority group categorized around the globe is the group of Left-handers and at several times they face disadvantaged situ- ations due to left handedness paralleled to right handers. Numer- ous studies demonstrated association between left-handedness and different health problems ranging from learning disorders to breast cancer and decreased longevity. This paper is based on the concept that there might be some difference between the handed- ness and bite force. Dissemination of handedness in a populace possess structures of directional irregularity in which non-racemic combination of two kinds of laterality is present [1]. In human around the globe, there is a Harmonious inclination for preferring the right hand as the prevalence of left handed people is around 10% of population in most of the cultures [1-4]. It is suggested from this fact that the change to the right has been determined on general preconcep- tion towards right hand as compared to unintentional inclination- towards left hand [1, 2]. Numerous authors proposed that the evolution of right-handedness is based on convenience of using right hand for various activities as carrying and soothing of a baby or for eating food [5, 6]. Occlusal Bite force is the interocclusal force that is produced when the jaw is closed under the effect of jaw muscles as a re- sult of the coordination between different components of the Abstract Introduction: The aim of the study was to explore the difference between handedness and bite force among general population. Method: Bite force was recorded with an Occlusal Bite force meter (GM-10 Nagano Keiki Japan). A mean of three left sided and a mean of three right sided maximum voluntary bite forces were calculated and a fnal mean of the two were taken to fnd out the Mean Maximum Voluntary Bite force. The data was entered and analyzed in SPSS version 25.0. As descriptive statistics, percentage of gender distribution was calculated. Later on, Paired sample t test and independent sample t test was used to explore the bite force difference among right and left handed participants. Results: Paired sample t test used to calculate between group difference of Bite Force which was found to be signifcant (t= 2.895, P=.005). The results of independent sample t test revealed a signifcant difference between the handedness and the average force bite from left side of mouth (t (2, 68) = -3.08, P=.003). The results for the comparison of average bite force from right side of mouth and handedness was also found signifcant (t (2, 68) = 2.36, P=.02). Conclusion: The study explored the difference of handedness with the bite force which was found to be signifcant. The results explained that right handed people have higher bite force at right side of mouth on chewing whereas left handed people apply more force while biting with left side of mouth as compared to right side. This was the new fnding explored by performing this study.
