Abstract
Purpose: This preliminary hospital based study was designed to measure the mean maximum
bite force (MMBF) in healthy Indian individuals. An attempt was made to correlate MMBF with
body mass index (BMI) and some of the anthropometric features.
Methodology: A total of 358 healthy subjects in the age range of 18-47 years (mean
age = 26.66 ± 6.83) were selected following the selection criteria. Demographic details along
with general physical and facial parameters such as height, weight, facial form, facial profile,
arch form, and palatal contour were recorded in a predesigned proforma. The maximum
bite force was recorded on both (right and left) sides using a specially designed piezoelectric
transducer based device.
Results: The MMBF in Indian individuals was found to be 372.39 ± 175.93 Newton (N).
Males had significantly higher (P = 0.000) MMBF (448.47 ± 191.82 N) as compared to
females (296.31 ± 116.79 N). Facial form (P = 0.001) and palatal contour (P = 0.000)
showed a significant relationship with MMBF. Subjects having square facial
form (421.34 ± 187.32 N) showed significantly higher MMBF as compared to other facial forms,
that is, square tapered (358.86 ± 143.56 N; P = 0.038), ovoid (338.40 ± 163.02 N; P = 0.000) and
tapered (349.22 ± 184.82 N; P = 0.028). Subjects with flat palatal contour showed significantly
higher MMBF when compared to high (P = 0.002) and medium palatal (P = 0.002) contour.
Though facial profile was not significantly related to MMBF, it was significantly higher in subjects
having concave facial profile when compared to convex (P = 0.045) and straight (P = 0.039)
facial profile. BMI and arch form showed no significant relationship with MMBF.
Conclusion: The MMBF is found to be affected by gender and some of the anthropometric
features like facial form and palatal contour.
