BACKGROUND The European Academy of Paediatric Dentistry (EAPD) has long recognised the necessity of promoting further research and knowledge regarding the dental defect described as molar-incisor-hypomineralisation (MIH). Following the establishment by EAPD of the defect diagnostic criteria in 2003, the publication of various papers and a whole issue(More)
OBJECTIVES Immigrant children make up a large proportion of the school populations in many western cities. It is likely that their parents have different attitudes and knowledge of dental health than resident populations, and thus provide a challenge to public dental services. This study sought to map existing disparities in oral health among immigrant and(More)
Tooth-coloured restorative materials are being used increasingly more often in Class II preparations in permanent teeth. Using a practice-based study design, we aimed to assess the survival time of Class II restorations and to identify factors relevant to their longevity. Class II restorations (n = 4,030), consisting of resin composites (81.5%), compomers(More)
The study aimed to investigate caries prevalence in children using a severity grading diagnostic system, and to evaluate the influence of different diagnostic thresholds on the caries data. A group of 513 children, aged 5, 12 and 18 years, were examined clinically, and with available bitewing radiographs, by four calibrated examiners. The inter- and(More)
The aim was to measure variations in threshold for operative treatment of approximal caries in permanent teeth and the use of restorative materials, compared with results from studies conducted in Norway in 1983 and 1995. In 2009, a precoded questionnaire was sent electronically to 3,654 dentists with E-mail addresses in the member register of the Norwegian(More)
OBJECTIVE Long-term aim is to determine optimum interventions to reduce dental caries in children in disadvantaged communities and minimise the effects of exclusion from health care systems, of ethnic diversity, and health inequalities. DESIGN Generation of initial explanatory models, study protocol and development of two standardised measures. First, to(More)
OBJECTIVES To explore a possible relationship between the caries experience and pattern in the primary dentition at 5 years of age and the permanent dentition at 10 years of age. Further, to examine the possibility of predicting children in a caries-risk group at 5 years verified at 10 years of age. MATERIALS AND METHODS A sample of 186 children (90(More)
OBJECTIVE To assess the ability of multivariate models and single factors to correctly identify future caries development in pre-school children and schoolchildren/adolescents. STUDY DESIGN A systematic literature search for relevant papers was conducted with pre-determined inclusion criteria. Abstracts and full-text articles were assessed independently(More)
The aim was to study any variability in approximal and occlusal caries diagnoses and restorative treatment decisions among Swedish dentists. The material consisted of a pre-coded questionnaire sent to a random sample of 923 dentists with 4 items concerning approximal and occlusal caries diagnosis and restorative treatment decisions. Responses were received(More)
Tunnel restorations (n = 161) performed by 4 dentists were evaluated after a mean of 35 months in situ. Demineralized enamel was to be spared during preparation. The preparations were filled with a cermet glass ionomer (polyalkenoate) cement. Evaluation was carried out using clinical and radiographical criteria. During the observation period, approximately(More)
