    Prolematics of curved root canals
    Sadeghdoost, Amirreza; Juhasz, Alexander; Debreceni Egyetem::Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Suta, Péter; Hidi, Erika; Debreceni Egyetem::Fogorvostudományi Kar
    Root canal therapy is a complex procedure that faces difficulties stemming from intricate canal structures and pronounced bends. Achieving positive outcomes relies on precise measurement of canal dimensions, skilled maneuvering within the canals, and appropriate instrument selection. While manual instruments are useful, they demand careful handling to prevent mistakes. Incorporating rotary Nickel Titanium (NiTi) files following initial preparation with stainless steel hand files is a suggested strategy for effective treatment.

    Microleakage in dentistry
    Akter, Zain; Suta , Péter; Debreceni Egyetem::Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Martos, Renata; Juhász, Alexander; Debreceni Egyetem::Fogorvostudományi Kar
    Microleakage in the terms of dentistry is used to describe and explain the ‘diffusion’ of bacterial, oral fluids, ions and molecules into or between the tooth and the filling, obturating or luting material interface. Also, it can be used to detail the undetected passage of bacteria, fluids and molecules between the tooth surface and the restorative material or luting agent. The cause of such may be for example thermal and occlusal forces acting on a restoration, such leakage may also take place during gap formation at margins that are created during a cavity preparation for example. Due to the concept, ideology and factual representation of microleakage, Clinicians must make this a vital consideration during the operator’s treatment plan and during the diagnostic parameters. The materials that are used throughout each step of a procedure during a restoration therefore must be carefully analysed and put under scrutiny, to ensure that as minimal microleakage occurs. Microleakage being a hugely impactful factor to the longevity of the treatment that has been decided on by the operator. Such longevity if compromised and ultimately leads to failure can therefore have an impact on the operator’s career and reputation themselves. This thesis research will be investigating the mechanism, methods and techniques that are used in modern day dentistry to overcome the challenges that microleakage can present and pose. The aim is to do so by using articles, studies and publishments that have been produced by other scholars from around the globe. Using these publications, this thesis aims to compare the principles and methods that have been described in such studies and try to evaluate the use of techniques and their efficiency, that may and can be used throughout many fields of dentistry in order to minimize the creation and production of microleakage, therefore leading to a more dependable treatment for the patients.

    Bioceramic sealers
    Salah, Mohammed Yasir; Juhász, Alexander; Debreceni Egyetem::Fogorvostudományi Kar::Konzerváló Fogászati nem önálló Tanszék; DE--Fogorvostudományi Kar; Renáta, Martos; Enikő Rita, Tóth; Debreceni Egyetem::Fogorvostudományi Kar::Konzerváló Fogászati nem önálló Tanszék; Debreceni Egyetem::Fogorvostudományi Kar::Konzerváló Fogászati nem önálló Tanszék
    Bioceramic sealers are advanced materials used in dentistry for root canal treatments. These sealers are composed of bioactive ceramics that possess unique properties, making them highly suitable for endodontic applications. Unlike traditional sealers, bioceramic sealers are hydrophilic, allowing them to form a tight bond with the tooth structure and create a hermetic seal within the root canal system. Their bioactive nature promotes the formation of hydroxyapatite, aiding in the repair and regeneration of damaged tooth structures. Biocompatibility and antibacterial properties are other notable features of these sealers, reducing the risk of post-treatment infections. Overall, bioceramic sealers offer an innovative solution for effective root canal therapy while contributing to improved long-term outcomes and patient comfort.

    Complications of periodontal diseases during pregnancy
    Abdalmalak, Meret; Skopkó , Boglárka Emese; Debreceni Egyetem::Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Szepesi, Márta; Lukács, Levente
    Pregnancy causes a number of physiological changes in a woman's body, both general and ones that affect the oral cavity specifically. The body gradually becomes more susceptible to oral infections as a result of changes in host immunity, twisted and dilated microvasculature, increased permeability of oral blood vessels, and altered estrogen and progesterone levels brought on by hormonal swings throughout pregnancy.

    Different methods of recording centric relation
    Beikzadeh, Dayan; Suta, Gábor; DE--Fogorvostudományi Kar
    The thesis emphasizes the importance of establishing an effective and balanced occlusion in treating patients wearing removable total or partial dentures. The various techniques discussed in the paper, including Gothic arch tracing, chin-point guidance, bimanual or bilateral manipulation, leaf gauge, and Lucia jig, can be used to determine the condylar location in CR. The wax rims method is more suitable for both the operator and the patient, while the Gothic arch method is more skill sensitive and requires longer chair-side time for both the dentist and the patient. Dentists should be knowledgeable about the advantages and disadvantages of each technique and combine more than one technique to minimize the limits of each unique method. Ultimately, maintaining an effective and balanced occlusion is critical to avoid unbalanced occlusal loads that might damage the supporting tissues and make the dentures unstable.
