METHODS The original group comprised 135 randomly selected 15-year-old subjects who were examined clinically and by means of a(More)
The aim of this summary of a longitudinal investigation on temporomandibular disorders (TMD) was to present the prevalence figures of signs and symptoms of TMD and certain other examined variables, and the correlations between these variables, over a 20-year period.

A clinical examination was(More)
Longitudinal studies on tooth mortality are rare but the reasons for tooth mortality have been studied by several authors. The aims of this investigation were to study the reasons for and incidence of tooth mortality in an earlier described Swedish population of 200 patients on two occasions with an interval of 5-7 years, and to see if the reasons for(More)
AIMS These were to 1) estimate the prevalence of subjective symptoms and clinical signs of temporomandibular disorders (TMD) in children and adolescents in the city of Jönköping, Sweden, 2) follow possible variations in TMD signs and symptoms over a 20-year period, and 3) study possible associations between TMD symptoms and signs and factors of interest.

Longitudinal studies of endodontic treatment are rare. The purpose of this investigation was to study changes in frequency, technical standard and treatment need in a Swedish population with an interval of 5-7 years. The number of endodontically treated teeth in the population increased while the number of periradicular radiolucencies was at about the same(More)
AIM To re-examine a population after 20 years and evaluate changes in prevalence of endodontic treatment and apical periodontitis, as well as the technical quality of root fillings. METHODOLOGY One hundred and fifteen out of an original 200 patients living in the northern part of Sweden were re-examined with a full mouth radiographic survey after 20(More)
An epidemiologic sample of 84 subjects was followed longitudinally from the age of 15 to 25 years concerning clinical signs of craniomandibular dysfunction. There was an obvious fluctuation of the clinical signs of craniomandibular disorders over the 10-year period. No statistically significant change of any of the separate clinical signs or the clinical(More)
