1. 1. Mandibular third molar removal : patient preferences, assessments of oral surgeons and patient flows

   Författare :Rolf Liedholm; Malmö högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Patient preferences; Decision making; Molar; third; Tooth extraction; Patient care management; Radiology;

   Sammanfattning : Operativt avlägsnande av visdomständer i underkäken utgör en stor del av verksamheten vidlandstingens specialistkliniker i käkkirurgi i Sverige. Under 1980- och 1990-talen beräknadesårligen 20-25.000 visdomständer ha avlägsnats vilket utgjorde ca 60 % av operationsvolymenvid dessa kliniker. LÄS MER

3. 2. Molar Incisor Hypomineralization

   Författare :Tobias G Fagrell; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Teeth; Molar Insicor Hypomineralisation; hypomineralisation; Enamel; Etiology; ozone; Scanning electron microscopy;

   Sammanfattning : Overall aim: The general objective of this thesis was to enhance the understanding of Molar Incisor Hypomineralization (MIH) in areas of the histological, chemical and mechanical properties of the hypomineralized enamel, objective and subjective clinical symptoms in relation to bacteria findings. Further, to estimate a time for onset of the disturbance and investigate possible etiological factors. LÄS MER

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. 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.

7. 5. Cellulose degradation in pulp fibers studied as changes in molar mass distributions

   Författare :Rickard Berggren; KTH; []
   Nyckelord :cellulose; kraft pulp; birch; spruce; ozonation; acid hydrolysis; degradation; MMD; size-exclusion chromatography; light scattering; molar mass; chain scission;

   Sammanfattning : In this thesis, size-exclusion chromatography (SEC) of woodpolymers dissolved in lithium chloride/N,N-dimethylacetamide(LiCl/DMAc) has been used to characterize the molar massdistributions (MMD) of wood polymers in pulp fibers afterchemical degradation.Characterization of birch kraft pulps subjected to ozonedegradation and acid hydrolysis, respectively, rendereddifferent changes in the MMD.
