  1. 16. Archaeological dental calculus reveals patterns of dietary shifts related to the farming transition in Africa

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Ivany Jocelyne Argueta Mejia; [2023]
    Nyckelord :dental calculus; ancient DNA; oral microbiome; shotgun sequencing; biofilm; metagenomics;

    Sammanfattning : Archaeological dental calculus represents a depositional environment that entraps oral microbes, and debris of dietary, environmental, and cultural material that entered the mouth throughout the host’s life. Hence, they represent valuable archives of information about the host’s lifestyle, health, and environment. LÄS MER

  3. 17. Utmattning av implantat-förankrade bro-konstruktionermed ett frihängande led och två olika fixturdiametrar. En pilotstudie

    Kandidat-uppsats, Malmö universitet/Odontologiska fakulteten (OD)

    Författare :Ahmed Yassin; Mohammed Al-Haideri; [2023]
    Nyckelord :Cantilever; Dental implants; Fixed dental prosthesis; Fatigue; Fracture strength; Implant angulation; Brotthållfasthet; Dentala implantat; Fast protetik; Frihängande led; Implantatvinkling; Utmattning.;

    Sammanfattning : Purpose: The purpose of this study is to evaluate how implant-supported fixed dental prosthesis (FDP) restorations with a cantilever at abutment level resist fatigue by dynamic loading and thermocycling depending on the fixture diameters.   Material and method: The study involved two groups with three specimens in each group, based on the diameter of the fixture, 3.

  4. 18. The effect of calcium silicate-based cements on viability and differentiation of human stem cells from the dental apical papilla. : Future aspects in endodontic regeneration.

    Master-uppsats, Umeå universitet/Wallenberg centrum för molekylär medicin vid Umeå universitet (WCMM); Umeå universitet/Tandläkarutbildning

    Författare :Lahood Abdalla; Bagir Soltani; [2023]
    Nyckelord :MTA; Biodentine; SCAP; Regenerativ endodonti; endodonti; traumatiserade tänder; tänder; unga tänder;

    Sammanfattning : Introduction: Pulp necrosis in immature permanent teeth stops root development and may lead to higher risk of cervical fractures and a challenging treatment. Regenerative endodontic treatment (RET) aims to continue tooth development and implies the use of calcium silicate-based cements, such as Mineral trioxide aggregate (MTA) and Biodentine to seal the root canal.

  5. 19. Kunskap om dental erosion samt konsumtion av sur dryck bland ungdomar : En tvärsnittsstudie

    Kandidat-uppsats, Karlstads universitet/Institutionen för hälsovetenskaper (from 2013)

    Författare :Mikaela Frycklund; Sofia Larsson; [2023]
    Nyckelord :Acidic drink; adolescents; consumption; dental erosion; knowledge; Dental erosion; konsumtion; kunskap; sur dryck; ungdomar;

    Sammanfattning : Introduktion/Bakgrund: Dental erosion är en irreversibel kemisk process som innebär förlust avtandsubstans. Läskförsäljning i Sverige ökar varje år och ungdomars konsumtion av läsk är en bidragandeorsak till dental erosion. LÄS MER

  7. 20. Design of a lightweight toothbrush with low environmental impact

    Master-uppsats, Lunds universitet/Innovation

    Författare :Johan Hammarberg; [2023]
    Nyckelord :Product development; Injection molding; Dental products; Toothbrush handle; Mold flow analysis; Technology and Engineering;

    Sammanfattning : The work presented in this report investigates how a toothbrush can be designed to be lightweight and at the same time fast to manufacture. If a low weight and short manufacturing time can be obtained, several other advantages can be had, such as reduced carbon dioxide footprint, less need of material, and more cost-efficient manufacturing.
