  2. 1. Influence of a dental ceramic and a calcium aluminate cement on dental biofilm formation and gingival inflammatory response

    Author : Katarina Konradsson; Jan van Dijken; Rolf Claesson; Lars Gahnberg; Umeå universitet; []
    Keywords : cements; ceramics; cytotoxicity; dental biofilm; gingivitis; interleukin-1; oral hygiene; resin composite;

    Abstract : Dental restorative materials interact with their surrounding oral environment. Interaction factors can be release of toxic components and/or effects on biofilm formation and gingiva. In the end of the nineties, a calcium aluminate cement (CAC) was manufactured as a “bioceramic” alternative to resin composite. READ MORE

  4. 2. Effect of ozone on dental caries and on cariogenic microorganisms

    Author : Elisabeth Johansson; Jan van Dijken; Rolf Claesson; Ingrid Andersson Wenckert; Lena Karlsson; Ivar Espelid; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental caries; Ozone; Cariogenic microorganisms; odontologi; Odontology;

    Abstract : There are a number of unanswered questions regarding new caries preventive methods such as ozone treatment as well as novel caries detection methods that monitor and evaluate these preventive methods. This thesis seeks answers to some of these questions. READ MORE

  5. 3. Calcium aluminate cement as dental restorative : Mechanical properties and clinical durability

    Author : Karin Sunnegårdh-Grönberg; Jan van Dijken; Preben Hørsted Bindslev; Umeå universitet; []
    Keywords : mechanical properties; clinical; restorations; ceramic; cement; resin composite; adaptation; SEM; odontologi; Odontology;

    Abstract : In 1995, the Swedish government recommended the discontinuation of amalgam as restorative in paediatric dentistry. Because the mercury content in amalgam constitutes an environmental hazard, its use has declined. READ MORE

  6. 4. In vivo evaluations of the neutralizing effect of a hydroxyl ion-releasing resin composite and a prophylactic gel on plaque acidogenicity : measured by the microtouch method

    Author : Anitha Persson; Jan van Dijken; Peter Lingström; Anette Oliveby; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caries; clinical; buffering; elderly; plaque pH; resin composite; restorations; microorganisms; ODONTOLOGY; ODONTOLOGI;

    Abstract : The prevalence of dental caries has decreased dramatically in most developed countries since the sixties and the number of remaining teeth in adults has increased during the last decades. Elderly as a group will during aging become an increasing risk group for caries. READ MORE

  7. 5. Dealing With Reservoir Effects in Human and Faunal Skeletal Remains : Understanding the radiocarbon dating of aquatic samples

    Author : Jack Dury; Gunilla Eriksson; Kerstin Lidén; Peter Jordan; Johannes van der Plicht; Philippa Ascough; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Radiocarbon Dating; Reservoir Effects; Bayesian; Modelling; Palaeodiet; Stable Isotopes; Skeletal Remains; Collagen; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

    Abstract : Archaeology relies on the ordering of past events to study cultural developments. This has traditionally been achieved by looking at the stratigraphic depths of materials relative to one another. In this way, chronologies of past technological progressions and stylistic changes can be built. READ MORE
