Abstract
Objective To compare maximum incisor (MBFinc) and molar (MBFmol) bite forces regarding the type of dentition and sex and to establish a relationship between them.Methods One hundred-five individuals were divided into 3 groups: G1 – 22 females/13 males (4–5 years); G2 – 15 females/20 males (11–12 years); and G3 – 16 females/19 males (17– 18 years). The maximum bite force was recorded with an extraoral measuring device. Three measurements were recorded: right and left molar level (MBFmol) and incisor level (MBFinc). The ratio %MBFinc/MBFmol was determined.Results MBFmol and MBFinc values increased with age (p < 0.05). MBFmol showed statistically higher values than MBFinc (p < 0.05), when compared within the same group.Conclusion MBFinc and MBFmol increased with age. For all groups, MBFmol showed higher values than MBFinc, and %MBFinc/MBFmol ratio was 1:2. No differences were found in maximum bite force between sexes.
