Krone på tann kontra fylling. Kliniske momenter til grunn for anbefaling
(Master thesis; Mastergradsoppgave, 2021-05-20)Bakgrunn: Målsetningen med denne oppgaven er å finne ut om det finnes gode kliniske retningslinjer for valg av optimal tannrestaurering, da man som kliniker må vurdere dette nærmest daglig. Alternativene kan være en intrakoronal restaurering, benevnt fylling, eller en ekstrakoronal restaurering, benevnt krone. Vi har derfor laget en PICO: Hos en pasient med en tann med indikasjon for restaurering, ... -
Tannhelseinformasjon på norske blogger
(Master thesis; Mastergradsoppgave, 2021-05-20)Det har blitt vanlig å søke etter helseinformasjon på nett, og dermed også tannhelseinformasjon. Blogger er en del av sosiale medier i Norge, og hensikten med oppgaven var å undersøke hva norske bloggere skriver om tannhelserelaterte tema. Vi ønsket også å undersøke om noen av innleggene relatert til tannhelse var reklame for et firma, og i så fall hvor mange. I tillegg ønsket vi å kartlegge hvilke ... -

The use of commercial ELISA kits in measuring CA6 concentration of saliva
(Mastergradsoppgave; Master thesis, 2021-05-20)Introduction: Carbonic anhydrase 6 (CA6) is the only secreted member of the carbonic anhydrase enzyme family. This enzyme catalyzes the reversible hydration of carbon dioxide: CO2 + H2O ⇔ H+ + HCO3-. The dehydration reaction contributes to net acidification in several tissues and biological fluids. Salivary CA6 attaches to the enamel and predisposes to caries probably by acidifying the dental biofilm ... -

Retensjon av sementerte protetiske erstatninger
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-17)Flere faktorer bidrar til å påvirke klinisk holdbarhet på sementerte tannrestaureringer. Fordi preparering av tannvev til en ekstrakoronal restaurering er irreversibel, er det utstrakt forskningsaktivitet for å finne metoder og teknikker for å minimere biologisk skade og utvikle nye biomaterialer som krever mindre avvirkning av tannvev. Derfor blir vi stadig bombardert med nye «bedre» eller «enklere» ... -

Fluoride in the drinking water and dental caries experience by tooth surface susceptibility among adults
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-04)<p>Background: Dental caries is the most prevalent non-communicable health condition globally. The surface-based susceptibility hierarchy indicates that surfaces in the same group have similar susceptibility to caries, where the most susceptible group consists of occlusal surfaces of first molars and buccal surfaces of lower first molars, and the least susceptible surfaces are smooth and proximal ... -
Molar - Incisor Hypomineralization (MIH) and long - term exposure to 25 - hydroxyvitamin D, measured as Bone Mineral Density (BMD) in adolescents from Northern Norway: an epidemiological study based on the Tromsø study: “Fit Futures”
(Master thesis; Mastergradsoppgave, 2020-05-20)Aims: The basis of the study was to evaluate if MIH could be related to low levels of vitamin D. Vitamin D is understood to have a key role in both enamel and dentin formation, and maturation, in addition to skeletal integrity. BMD could give a clue of the participants’ long - term vitamin D exposure, indirectly giving a reflection of a possible vitamin D impact on enamel mineralization. Materials ... -
