    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.

    Sammanfattning : Amalgam has been used as a dental restorative material for centuries, but its potential health effects and biopersistance has lead to a decreased use especially in the Nordic countries. New materials have been introduced, partly to replace the mercury containing amalgam and partly because of esthetical reasons. LÄS MER

  4. 3. Photocuring of multifunctional monomers initiated by camphorquinone / amine systems for application in dental restorative resins

    Författare :Nie Jun; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Photocuring; Dental restorative resins; Photoinitiator system: Cainphorquinone amines; Monomers: Meth acrylates; Photoinitiated polymerization kinetics;

    Sammanfattning : This thesis deals with the photopolymerization of mono-, di- and trifunctional monomers initiated by carnphorquinone (CQ) alone and/or with different amines (AMH) as coinitiators in air as well in nitrogen. The kinetics of photopolymerization was measured by photoisothermal calorimetry (photo-DSC), which allowed the measurement of the rate of polymerization (Rp), maximum rate of polymerization (Rpmax), time of inhibition (tinh), time at which Rpmax was obtained (tmax), double bond conversion (p) and maximum double bond conversion (pmax).

  5. 4. Effect of light power density variation on dental light-cure resin composites

    Författare :Nazanin Emami; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Sammanfattning : Dental resin based composites are tooth-colored filling materials composed of synthetic resins and particulate ceramic reinforcing filler particles. The resin system also contains molecules that promote and/or modify the polymerisation reaction of the dimethacrylate resin monomers. LÄS MER
