This investigation consisted of 188 mixed dentitoned children (91 boys, 97 girls, mean
age 9.04 years) who visited Department of Pediatric Dentistry of Seoul National
University Hospital. The subjests were interviewed for symptoms and oral parafunction,
and examined clinically for occlusal status, joint sound, muscle & joint tenderness and
mandibular movements to investigate the distribution of signs and symptoms of
temporomandibular disorder, and analyzed with regard to relatinships between etiologic
factors such as multiple loss of teeth, malocclusion, oral parafunction, trauma to the face
and signs and symptoms of temporomandibular disorder.
The following results were obtained.
1. 12.2% and 53.2% of the children reported subjective symptom and objective
symptom and there was no significant differences between the sexes and ages
regarding the prevalence of signs and symptoms of temporomandibular disorder.
2. Clicking and crepitus were found in 9.0% and 2.2% of children, and 40.4% and
28.7% of children reported muscle tenderness and joint tenderness on palpation, and
there was no significant differences between the sexes regarding the prevalence of signs
and symptoms of temporcmandibular disorder
3. The distribution of Angle's classification was found 56.9% in Class 1,19.7% in
Class ¥±, 23.4% in Class ¥±, and correlations were found between malocclusion and
subjective symptom(P<0.05).
4. The prevalence figures of posterior cross bite, anterior cross bite, openbite, deep
and occlusal interference at the terminal hinge movement were 3.2%, 19.1%, 5.3%, 10.1%,
and 9.0% respectively, and there was no significant difference between these factors
regarding the prevalence of signs and symptoms of temporomandibular disorder.
5. Multiple loss of teeth, oral parafunction, trauma to the face were reported in 9.0%,
27.7%, and 19.1% of children respectively, and there was no significant difference
between these factors regarding the prevalence of signs and symptoms of
temporomandibular disorder.
Strong correlations were found between subjective symptom, joint tenderness and
recurrent headache(P<0.01), and lateral joint tenderness was correlated to muscle
tenderness especially masseter muscle (P<0.01), There were also correlations between
recurrent headache and muscle tenderness(P<0.05).
