Bilateral bite force was measured in a sample of 457 subjects (231 mal
es and 226 females) from 6 years through 20 years. The mean maximum bi
te force was found to increase from 78 Newtons at 6 to 8 years to 176
Newtons at 18 to 20 years. While earlier studies have shown adult male
s have a greater mean bite force than females, this difference is not
evident during growth and development. Gender-related bite force diffe
rence likely develops during the postpubertal period in association wi
th greater muscle mass development in males.
