    Area of Science:

    • Dentistry
    • Pediatric Health
    • Epidemiology

    Background:

    • Mandibular dysfunction is a prevalent condition affecting children.
    • Longitudinal data on its progression in pediatric populations are crucial for understanding development.
    • Previous cross-sectional studies suggest age-related differences in prevalence.

    Purpose of the Study:

    • To longitudinally assess clinical signs and subjective symptoms of mandibular dysfunction in children.
    • To compare the prevalence and frequency of symptoms between 11- and 15-year-old age groups.
    • To track changes in signs and symptoms over a four-year interval.

    Main Methods:

    • A cohort of 119 children was studied at ages 11 and 15.
    • Clinical examinations identified signs of mandibular dysfunction.

  • Subjective questionnaires captured self-reported symptoms related to the masticatory system.

    • Main Results:

    • 66% of children exhibited clinical signs of mandibular dysfunction at both ages.
    • Subjective symptoms were reported by 62% (11-year-olds) and 66% (15-year-olds).
    • Moderate to severe signs increased with age (11% to 17%), as did frequent symptoms (3% to 11%).
    • Both clinical signs and frequent subjective symptoms showed an increase over the four-year period.

    Conclusions:

    • Mandibular dysfunction is common and can progress during childhood and adolescence.
    • Longitudinal findings align with previous cross-sectional studies on age-related prevalence.
    • Early identification and monitoring of pediatric mandibular dysfunction are warranted.
