Materials And Methods: The study group consisted of 139 children with CL(P) (80 subjects aged 5 years and 59 aged 10 years) and 313 age-matched non-cleft controls. All children were examined by one of two calibrated examiners.

Idiopathic resorption of impacted mesiodentes: a radiographic study.

Background: Although a large number of mesiodentes are left in situ, only a few are found in radiographs from epidemiological studies of adult populations. This leads to the development of a hypothesis that mesiodentes may be resorbed and disappear over time. The aim of this study was to radiographically investigate the frequency of resorptions and pathologies in relation to mesiodentes left in situ.

Evaluation of preventive programs in high caries active preschool children.

Although caries prevalence in preschool children has dramatically decreased during the last decades it is still a large problem for a minor group of these children. Great efforts have been invested in finding effective preventive programs for the high caries active preschool children. However, few studies have evaluated and discussed which approach will give the best effect.

Aetiology of severe demarcated enamel opacities--an evaluation based on prospective medical and social data from 17,000 children.

During the 1970s dentists reported an increasing prevalence of a "new" type of enamel disturbance.The disturbance was very specific, with areas of demarcated hypomineralised enamel, and was mostly found in permanent first molars and incisors. Several studies have tried to reveal the aetiology behind the enamel disturbance but sofar no clear factors correlated have been found.
