    Summary
    This summary is machine-generated.

    Maximal bite force and grip strength were measured in Skolt Lapps. Males exhibited higher values than females, and bite force decreased with age and tooth loss.

    Area of Science:

    • Anthropology
    • Physiology
    • Biomechanics

    Background:

    • Investigating maximal bite force and finger-thumb grip strength provides insights into human physical capabilities.
    • Understanding variations in these parameters across demographics and age groups is crucial for physiological and anthropological studies.

    Purpose of the Study:

    • To measure and compare maximal bite force and finger-thumb grip strength in Skolt Lapps.
    • To analyze the influence of sex, age, and dentition status on these physical parameters.

    Main Methods:

    • A specially devised apparatus was used to measure maximal bite force at the molar and incisor regions.
    • Finger-thumb grip strength was assessed by measuring the force exerted between the thumb and forefinger.
    • Data were collected from 125 Skolt Lapps aged 15 to 65.

    Main Results:

    • Males demonstrated significantly higher mean bite force and grip strength than females.
    • Bite force showed a notable decrease with increasing age, particularly in females, likely due to dentition deterioration.
    • Individuals with natural teeth exhibited greater bite force compared to denture wearers, with a positive correlation between the number of natural teeth and bite force.

    Conclusions:

    • Sex is a significant factor influencing maximal bite force and grip strength in the studied population.
    • Age-related decline in dentition substantially impacts bite force, highlighting the importance of oral health.
    • The findings underscore the relationship between natural dentition and masticatory/grip strength.
