Prognosis of non-vital incisors after apexification using bioceramics: a retrospective study.

Purpose: To evaluate the outcome of apexification using bioceramics in immature permanent teeth, and to study the factors influencing treatment outcome and frequency of spontaneous cervical root fractures.

Methods: Forty-six children with 51 non-vital permanent incisors treated with a bioceramic apical plug were included. Mean age at pulp necrosis was 9.

Molar-Incisor Hypomineralisation: Severity, caries and hypersensitivity.

Objectives: To investigate distribution of affected teeth and severity of molar-incisor hypomineralisation (MIH) in 8-9-year-old children. A second aim was to study association between severity of MIH and hypersensitivity, caries, and affection of incisors and second primary molars (SPM).

Methods: A total of 3013 children in one age cohort participated in a cross-sectional study, of which 851 children were diagnosed with MIH.

Prolonged breastfeeding and dental caries in preschool children.

Purpose: To explore breastfeeding from 6 to 18 months of age and to study the association between breastfeeding and caries prevalence at 5 years of age.

Methods: The study included 1088 children from one Norwegian county and was based on the Norwegian Mother, Father and Child Cohort Study (MoBa). The children had clinical dental examination at 5 years of age, and parents answered a questionnaire, which included information on breastfeeding, oral health behaviour and child characteristic.

Molar-incisor hypomineralisation in Norwegian children: Prevalence and associated factors.

This study investigated the prevalence and associations of molar-incisor hypomineralisation (MIH) in 8-9 year-old children in Oslo. A total of 3013 children in one age cohort participated in the study during their regular dental examination at the Public Dental Service. Hypomineralised enamel defects were recorded according to the European Academy of Paediatric Dentistry criteria for MIH.

Fissure sealing and caries development in Norwegian children.

Purpose: To explore the use of fissure sealing as a caries preventive method by describing characteristics of children who had received sealants and to study associations between sealing and caries prevalence at 12 years of age.

Methods: The study included 3075 children examined at 5 and 12 years of age. Data were collected by clinical examination and questionnaire to parents.
