    Mandibular dysfunction signs increase with age, while mobility decreases. Headache prevalence varies by age and sex, correlating with stress, parafunctions, and dental factors.

    Area of Science:

    • Dental Science
    • Public Health

    Background:

    • Mandibular dysfunction (MD) encompasses temporomandibular joint (TMJ) disorders, affecting masticatory function and quality of life.
    • Understanding the epidemiological characteristics of MD signs and symptoms is crucial for targeted public health interventions.

    Purpose of the Study:

    • To investigate the age and sex-specific prevalence of various signs and symptoms associated with mandibular dysfunction.
    • To explore correlations between demographic factors, parafunctions, stress, and the occurrence of mandibular dysfunction.

    Main Methods:

    • A cross-sectional study involving 600 randomly selected urban individuals.
    • Assessment of mandibular mobility, TMJ sounds, and other objective dysfunction signs (Di-I, Di-II, Di-III).
    • Data collection on headache occurrence, parafunctions, stress levels, and dental-occlusal factors.

    Main Results:

    • Significant sex-based differences in mandibular mobility were observed, with a general decrease in mobility correlating with increasing age.
    • Objective signs of dysfunction, including impaired mobility and TMJ sounds, showed an increased prevalence with advancing age.
    • Headache occurrence peaked in distinct age brackets for males and females, indicating age- and sex-specific patterns.

    Conclusions:

    • Age and sex are significant factors influencing the presentation and prevalence of mandibular dysfunction signs and symptoms.
    • Mandibular dysfunction is multifactorial, with strong associations found between headache, parafunctions, stress, age, and specific dental-occlusal conditions.
    • Further research into the complex interplay of these factors is warranted for effective management strategies.
