ABSTRACT
On the basis of a series of dental models from children between five and nine years (twice-yearly examination) with final models being made of 319 of these children at the age of 16, determinations were made of the rotation of the permanent central lower incisors 'shortly after complete eruption of the cutting edge' at the age of 16. The study showed that spontaneous correction amounts to 53% and 60% respectively for an original mesio-lingual rotation (type less than 90 degrees) and for an original disto-lingual rotation (type greater than 90 degrees).

The aim of this study was to measure the relative importance of a number of psychologic and social variables in explaining the severity of symptoms of functional disturbances of the stomatognathic system. 261 non-care seeking patients with respect to pain and dysfunction of the stomatognathic system were examined. The total sample consisted of two subgroups: Group 1 (n = 130) with a complete natural dentition and Group 2 (n = 131) wearing complete maxillary and mandibular dentures. Symptoms of functional disturbances of the stomatognathic system were assessed using two questionnaires. One was derived from the Anamnestic Dysfunction Index and the other was an extended questionnaire which included accessory symptoms frequently mentioned in the literature. The patients also completed the Hopkins Symptom Checklist, the Dutch Personality Inventory, and a Dutch form of the Minnesota Multiphasic Personality Inventory. In both patient subgroups symptoms of functional disturbances of the stomatognathic system were significantly correlated with patient's sex and a complex of highly intercorrelated psychologic variables: psychoneurotic- and somatic symptoms, neuroticism, negativism, and somatization.

The aim of this study was to measure the relative importance of a number of psychologic and social variables in explaining the severity of signs of functional disturbances of the stomatognathic system. A group of 261 non care seeking patients with respect to pain and dysfunction of the stomatognathic system were examined. The total sample consisted of two subgroups: Group one (n = 130) with a complete natural dentition and Group two (n = 131) wearing complete maxillary and mandibular dentures. Signs of functional disturbances of the stomatognathic system were assessed using the Clinical Dysfunction Index and a Palpation Test. The patients also completed the Hopkins Symptoms Checklist, the Dutch Personality Inventory and a Dutch form of the Minnesota Multiphasic Personality Inventory. Patient education, age and sex were also registered. In both patient subgroups signs of functional disturbances of the stomatognathic system were significantly correlated with patient's sex and a complex of highly intercorrelated psychologic variables: psychoneurotic and somatic symptoms, neuroticism and somatization.
