Tooth loss and remaining occlusion in a Dutch population.
The aim of this study was to gain a better insight into the tooth-loss pattern in terms of frequency, location and impaired occlusion. The sample, stratified according to socio-economic class and age, consisted of 750 subjects. The investigation was done by questionnaire and clinical examination. The non-response was small (15%). With increasing age, more teeth were missing. In the lower socio-economic group more teeth were missing than in the higher socio-economic group. The percentage of totally edentulous persons as well as the percentage of persons with one edentulous jaw increased with age. Also, the percentage of antagonistic tooth contacts declined with increasing age. The following order was found in decreasing contacts: first premolar, second premolar, second molar and first molar. In all strata the percentage of antagonistic contacts in the premolar area was larger than in the molar area.
