    This study establishes normal lip parameters in 500 individuals, detailing measurements for lip size, tissue elasticity, and muscle strength. Findings provide a baseline for understanding typical lip function across diverse demographics.

    Area of Science:

    • Anatomy
    • Physiology
    • Biometrics

    Background:

    • Understanding normal lip parameters is crucial for various medical and research applications.
    • Previous studies may lack comprehensive data across diverse age groups and sexes.
    • Establishing normative data is essential for comparative analyses.

    Purpose of the Study:

    • To define normal anthropometric and functional lip parameters in a large, diverse cohort.
    • To investigate age and sex-related variations in lip characteristics.
    • To provide a normative dataset for clinical and research use.

    Main Methods:

    • Studied 500 individuals across all age groups and sexes.
    • Measured intercommissural distance, soft-tissue gape, oral access, and lip elasticity.

  • Assessed lip curtain height via sulcus depths and orbicularis oris muscle strength using a pommeter.
  • Evaluated lip sensation using two-point discrimination tests.

    • Main Results:

    • Detailed normative values for all measured lip parameters were established.
    • Significant differences were observed in certain parameters across age and sex groups (p<0.01).
    • Orbicularis oris strength and lip sensation showed distinct patterns.

    Conclusions:

    • This study provides a comprehensive normative dataset for key lip parameters.
    • The findings offer valuable reference data for clinical assessments and research.
    • Understanding these normal variations is vital for diagnosing and treating lip-related conditions.
