    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Preterm infants; adolescent; oral hygiene; gingivitis; dental caries; dental enamel; malocclussion; dental arch; tooth size; enamel hypomineralization; dentine; polarized light microscopy; X-ray microanalysis;

    Sammanfattning : ABSTRACT Preterm birth is associated with medical complications and treatments postnatally and disturbances in growth and development. Primary and permanent teeth develop during this postnatal period. LÄS MER

  3. 2. Clinical aspects of restorative treatment in the primary dentition

    Författare :Mirja Varpio; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Child; Child; Preschool; Cohort Studies; Composite Resins; chemistry; DMF Index; Dental Caries; epidemiology; microbiology; pathology; therapy; Dental Cavity Preparation; classification; Dental Enamel; pathology; Dental Restoration; Permanent; statistics numerical data; Follow-Up Studies; Glass Ionomer Cements; chemistry; Humans; Molar; Prevalence; Prosthesis Failure; Recurrence; Sweden; epidemiology; Tooth; Deciduous;

    Sammanfattning : The failure rate of restorative treatment in primary teeth was studied in a cohort of children born in 1981 and related to caries diagnosis, prevalence and distribution on different tooth surfaces, and compared with a cohort of children born in 1971. Concurrently, the longevity of composite resin in modified Class 2 cavities in primary molars was followed up and the resistance of deciduous and permanent enamel to acid adjacent to composite resin and glass polyalkeonate cement (GPA) was tested in vitro.

  4. 3. Enamel hypomineralization in permanent first molars. A clinical, histo-morphological and biochemical study

    Författare :Birgitta Jälevik; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescent; Calcium Metabolism Disorders; complications; Child; Child; Preschool; Dental Enamel; chemistry; Dental Enamel Hypoplasia; epidemiology; etiology; metabolism; pathology; Female; Humans; Male; Molar; pathology; Prevalence; Respiratory Insufficiency; complications; Spectrometry; Mass; Secondary Ion; Sweden; epidemiology;

    Sammanfattning : Hypomineralization in the permanent first molars was common in a group of 516 Swedish 8-year-old children. Ninety-five children (18.4%) had at least one molar with demarcated opacity. The incisors frequently displayed opacities concomitantly. LÄS MER

  5. 4. Dentofacial morphology in Turner Syndrome karyotypes

    Författare :Sara Rizell; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthodontics; Turner syndrome; genetics; karyotype; geno-phanotype correlation; anthropometrics; craniofacial morphology; dental arch; dental crown width; enamel; primary teeth; elemental composition;

    Sammanfattning : The overall aim of this thesis was to study dentofacial morphology in Turner syndrome (TS) versus controls and the influence hereupon from karyotype. One hundred thirty two TS females (5-66 years of age), from Göteborg, Uppsala and Umeå were participating. LÄS MER

  7. 5. Smoking, snuffing and oral health with special reference to dental caries

    Författare :Lena Hellqvist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carbohydrates; dental care habits; dental caries; nicotine-containing snus; nicotine-free snus; plaque pH; salivary factors; smokeless tobacco; smoking; snuff; socioeconomic factors; tobacco; Dental Hygiene; Oral hälsa; carbohydrates; dental care habits; dental caries; nicotine-containing snus; nicotine-free snus; plaque pH; salivary factors; smokeless tobacco; smoking; snuff; socioeconomic factors; tobacco;

    Sammanfattning : Background and aims: This thesis describes oral health and the use of tobacco with the emphasis on dental caries and Swedish snuff (snus). There appears to be a general opinion in Sweden that snus protects against caries, but there are no scientific studies that support these speculations. LÄS MER
