    Chewing efficiency in Skolt Lapps is strongly linked to dental status. Fewer natural teeth and denture use significantly impact the ability to effectively break down food, affecting chewing performance.

    Area of Science:

    • Oral health
    • Dental science
    • Human biology

    Background:

    • Chewing efficiency is crucial for nutrient absorption and overall health.
    • Dental status, including natural teeth and denture use, can influence masticatory performance.
    • Understanding these relationships is vital for assessing oral health in diverse populations.

    Purpose of the Study:

    • To evaluate chewing efficiency in a Skolt Lapp population.
    • To determine the association between dental status and chewing efficiency.
    • To compare chewing performance between individuals with natural teeth and denture wearers.

    Main Methods:

    • Assessed chewing efficiency using almonds as a test food in 139 Skolt Lapps (ages 14-65).
    • Recorded number of chewing strokes, swallowings, and chewing time.

  • Classified chewing efficiency on a scale of 1 (very good) to 5 (very poor).
  • Correlated chewing efficiency with the number of occluding pairs of teeth and denture status.

    • Main Results:

    • A clear association was found between chewing efficiency and dental state.
    • Individuals with fewer than 20 teeth exhibited poorer chewing efficiency.
    • Denture wearers showed statistically significantly better chewing efficiency scores compared to those with natural teeth.
    • Denture wearers required more chewing time before swallowing.

    Conclusions:

    • Dental status is a significant determinant of chewing efficiency.
    • The number of natural teeth and the use of dentures are key factors influencing masticatory performance.
    • Findings highlight the importance of maintaining adequate dentition for effective chewing.
