Bite force of the first permanent molar in relation to growth indices / Монголын Анагаах Ухаан

ABSTRACT

Background: Bite force is one indicator of the functional state of the masticator system that results from the action of jaw elevator muscles modified by the craniomandibular biomechanics [Bakke.M 2006]. Determination of individual bite force level has been widely used in dentistry. The correlations of maximum bite force are studied in terms of gender, age, weight, height, body type, previous history of orthodontic treatment have shown in earlier studies.Aim: The aim of this study is to determine relationship between of bite force of the first permanent molar and some growth indices of children.Materials and Method: A total of 276 children, aged 12–16 years, were randomly chosen from the secondary schools No.33, 57, 67. A dental examination was done by using a mouth mirror and probe under natural light. Bite force of the first permanent molar was measured by an occlusal force meter GM10. Body height and body weight were determined by RGZ–120–RT scale. The results were considered to be significant at p-values below 0.05; the SPSS 16.0 for Windows wasused.Result: The average of the first permanent molar’s bite force was 572.9±8.24N and it was more in male than in female. The bite of the first permanent molar had a significant positive correlation to the body height, body weight (p<0.05).Conclusion: The bite force of the first permanent molar increases throughout growth of children.
