A prospective long-term study of signs and symptoms of temporomandibular disorders in patients who received orthodontic treatment in childhood.

This investigation analyzed the influence of orthodontic treatment performed in childhood on the long-term development of signs and symptoms of temporomandibular disorders (TMDs). The original sample consisted of 50 consecutive patients (27 girls and 23 boys) with different morphological malocclusions, who were to receive orthodontic treatment. Their mean age at start of treatment was 12.

Predictors of bruxism, other oral parafunctions, and tooth wear over a 20-year follow-up period.

Aims: To analyze predictors of bruxism, other oral parafunctions, and tooth wear in a group of subjects who had been examined 20 years earlier.

Methods: Originally, 402 randomly selected 7-, 11-, and 15-year-old subjects were examined clinically and by means of a questionnaire. Twenty years after the first examination, 94% of the original group could be traced, and 320 (85%) completed and returned the questionnaire.

A 20-year follow-up of signs and symptoms of temporomandibular disorders and malocclusions in subjects with and without orthodontic treatment in childhood.

This investigation analyzes the influence of orthodontic treatment on signs and symptoms of temporomandibular disorders (TMDs) and different malocclusions during a 20-year period. Originally, 402 randomly selected 7-, 11-, and 15-year-old subjects were examined clinically and by means of a questionnaire for signs and symptoms of TMDs. The examination was repeated after five and ten years.

Predictors of signs and symptoms of temporomandibular disorders: a 20-year follow-up study from childhood to adulthood.

The aim of this study was to find possible predictors of signs and symptoms of temporomandibular disorders (TMD) in a long-term perspective. Baseline questionnaire and clinical examinations focusing on function and dysfunction of the masticatory system were performed in a sample of 402 subjects 7, 11, and 15 years old. After 20 years, 320 subjects (80% of the original sample) completed a similar questionnaire as at baseline.

Treatment received, treatment demand, and treatment need for temporomandibular disorders in 35-year-old subjects.

An epidemiological sample of 114 subjects was followed longitudinally from the age of 15 to 35 years with regard to treatment received, treatment demand, and treatment need for temporomandibular disorders (TMD). Some kind of TMD treatment had been provided to 18% of the subjects during the 20-year follow-up period. Eighty-five percent of those who had received previous TMD treatment reported that the treatment had had a positive effect on their symptoms.
