Comparison of biting forces in different age and sex groups: a study of biting efficiency with mobile and non‐mobile teeth

Abstract

This study aimed (1) to investigate the influences of sex, age and number of teeth on biting ability through a descriptive survey, and (2) to compare the biting ability between the subjects with and without mobile teeth in a case-control study. A total of 687 subjects cooperated in the descriptive survey. Each subject bit on a pressure detecting sheet with their maximum biting force. Three indices of biting ability: biting pressure (MPa), biting force (N) and occlusal contact area (mm2) were calculated from the impressed marks on the sheet using a high vision video processor system. These indices were correlated well with the number of teeth according to the multiple regression analysis. In the case-control study, matching procedures with sex, age and number of teeth were performed between the subjects with and without mobile teeth. No differences in the three indices were observed between the two well-balanced groups. The results showed that the number of teeth is most important to maintain biting ability, and that the presence of mobile teeth does not always reduce biting ability.

Association of bite force with ageing and occlusal support in older adults

“…14, 23 We found the bite force stronger in men (512 N) than in women (443 N), echoing the findings from previous studies. 23,24 This might be a result of difference in muscle strength.…”

“…The biting force correlates with the number of teeth and functional pairs of teeth 14 . Thirteen of our 17 patients were fully dentulous or showed only one missing tooth.…”

Muscle Fiber Type Composition, Fiber Diameter, Capillary Density in Temporalis and Masseter Muscles and Correlation with Bite Force

“…Several previous studies have reported bite force as a clinical indicator of masticatory performance. This parameter is correlated with craniofacial morphology (Tsunori et al), gender (Tate et al, 1994) age (Klitgaard et al, 1990) temporomandibular disorders (TMD) (Pizolato & Gaviao, 2007), and also with status, number and tooth mobility (Miyaura et al, 1999).…”
