  2. 1. 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

  4. 2. 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

  5. 3. Salivary glands and oral lesions in diabetes mellitus : an experimental and clinical study with special reference to the influence of metabolic control and duration of the disease

    Author : Carl-Olof Reuterving; Erik Hägg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes mellitus; salivation; salivary glucose; saliva; submandibular gland; pilocarpine; root surface caries; periodontal disease; alloxan; feeding behavior; rats; humans;

    Abstract : Diabetes mellitus is associated with several clinically significant abnormalities in the oral cavity and salivary glands, the most common being periodontitis, salivary gland enlargement and a sensation of dry mouth. The pre­valence of dental caries in diabetics is mostly reported to be decreased or unaffected. READ MORE

  6. 4. Optical based technologies for detection of dental caries

    Author : Lena Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: A conservative, non-invasive or minimally invasive approach to clinical management of dental caries requires diagnostic techniques capable of detecting and quantifying lesions at an early stage, when progression can be arrested or reversed. Objective evidence of initiation of the disease can be detected in the form of distinct changes in the optical properties of the affected tooth structure. READ MORE

  7. 5. Cariological and Salivary Studies in 70-Year-Old Cohorts

    Author : Cecilia Johanson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cohort differences; cross-sectional; dental health; elderly; epidemiology; lifestyle; longitudinal; medication; population study; saliva; socioeconomic;

    Abstract : Life expectancy after 65 years of age has increased markedly during the last decades, and is still increasing. The purpose of this thesis was to describe differences in dental health between 70- year-olds born in different years, to describe caries prevalence, incidence over a 6-year period in one cohort, and try to find risk factors for dental caries.
