Tétel Korlátozottan hozzáférhető Modern resin-based esthetic filling materialsIngvarsdóttir, Fanndís; Bukovinszky, Katalin; Department of biomaterials and prosthetic dentistry; DE--Fogorvostudományi Kar; Szalóki, Melinda; Bakó, József; Debreceni Egyetem::Fogorvostudományi Kar::Fogpótlástani TanszékDental resin-based composites have been the most commonly used material for dental restorations with a remarkable evolution since their inception. However, with most current composites, polymerization shrinkage and the following bacterial micro-leakage are mechanical properties that need to be improved. Therefore, filler composition has been in focus; with reductions in size that allows higher volume and provides better clinical performance and improved wear resistance. Yet this comes at a possibly harmful cost to both the dental practitioner and the patient. The polishing of the composites is done without the aid of water-cooling, leading to nanoparticles traveling unabated into the respiratory systems and through the olfactory epithelium into the brain. However, resin composite materials are considered less toxic and provide advanced esthetics, though their longevity is considered less than amalgam fillings because of recurrent caries. Looking to the future, we can expect composite materials that exhibit an antibacterial promoting layer that can help with re-mineralization of demineralized dentin, inhibit bacterial microleakage and inhibit recurrent caries with release of calcium and phosphate.Tétel Korlátozottan hozzáférhető Surgical treatment of furcation involved teethRezaei, Ali; Hernádi, Katinka; Debreceni Egyetem::Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Varga, István; Tar, Fábián; Debreceni Egyetem::Fogorvostudományi KarWhen bone resorption as a result of periodontal disease has been extended into the bi- or trifurcation of a multi-rooted tooth, it's clinically called as furcation involvement. This thesis is aimed to introduce furcation involvement including it's terminology, classifications, and diagnostic methods as well as different surgical and regenerative treatment modalities for furcation involved teeth.Tétel Korlátozottan hozzáférhető Treatment possibilities of retained caninesDarabiboroujeni, Shiva; Lukács, Levente; Debreceni Egyetem::Fogorvostudományi Kar::Dentoalveoláris Sebészeti nem önálló Tanszék; DE--Fogorvostudományi Kar; Kalas, Nándor; Hegedűs, Nándor; Debreceni Egyetem::Fogorvostudományi Kar::Dentoalveoláris Sebészeti nem önálló TanszékTo expose impacted canines associated with its situation, a variety of surgical and orthodontics procedures may be performed. The main aspects of the effective therapy of impacted canines include precise assessment, conservative handling of the soft tissues, choosing the most suitable surgical intervention, a firm fixation system, and the alignment of the orthodontic traction. Dentists can prevent the occurrence of ectopic eruption and the resulting retention of the canine by correctly evaluating and treating patients. The straightforward interceptive approach for preventing the impaction of permanent canines is the early removal of primary canines.Tétel Korlátozottan hozzáférhető Oral lichen planus: etiology, pathogenesis, diagnosis and managementHosseini, Seyed Ehsan; Tar, Ildikó; Debreceni Egyetem::Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Kulcsár, Tímea; Gebri, Enikő Zsuzsa; Debreceni Egyetem::Fogorvostudományi KarThis review aims to describe the characteristics of Oral Lichen Planus and factors that are involved in the initiation and progression of disease. Pathologic mechanisms behind this disease are discussed and available methods of diagnosis are suggested. Finally, complication of OLP and treatment options are explained. Lichen planus (LP) is a well known chronic inflammatory disease, affecting adults in 1-2% all over the world. There are six clinical forms of OLP: papular, plaque, reticular, bullous, atrophic and erosive. Apoptosis of epithelium cells is greatly elevated in OLP.Tétel Korlátozottan hozzáférhető Dietary Cancer PreventionLendrum, Astrid Candice; Nemes, Judit; Debreceni Egyetem::Fogorvostudományi Kar::Gyermekfogászati és Fogszabályozási Tanszék; DE--Fogorvostudományi Kar; Horvath, Dora; Torok, Judit; Debreceni Egyetem::Fogorvostudományi Kar::Arc- Állcsont- és Szájsebészeti Tanszék; Debreceni Egyetem::Fogorvostudományi Kar::Gyermekfogászati és Fogszabályozási TanszékGlobal statistics and risk factors for oral cancers.

The anatomy is complex, and the curvatures can be severe, so there could possibly be complex forms of curvature. The objectives of this thesis are to discuss in detail, the various steps in the therapy of curved root canals, the materials used in each step, and the techniques that can be used to achieve the goals of the steps being discussed. This thesis aims to educate both readers and dentists on the best way to manage the challenging clinical scenarios of curved root canals whilst carrying out root canal treatment.Tétel Korlátozottan hozzáférhető Minor Oral Surgeries In ChildhoodLeonidou, Georgios; Kovalecz, Gabriella; Debreceni Egyetem::Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Baksa, Brigitta; Bakos, Rudolf; Debreceni Egyetem::Fogorvostudományi Kar; Debreceni Egyetem::Fogorvostudományi KarMinor oral surgeries in children are procedures that performed routinely by dental health workers almost every day. A lot of kind of procedures can be done for different reasons and to treat different diseases and traumas. Such as are surgeries to soft and hard tissues, incisional and excisional biopsies. they can also be done in for the treatment of some acute orofacial infections and injuries.Tétel Korlátozottan hozzáférhető The potential impact and importance of salivary peptides in periodontitisYin, Ruohan; Varga, Istvan; Fogorvostudományi Kar::Parodontológiai nem önálló Tanszék; DE--Általános Orvostudományi Kar; Angyal, Janos; Toth, Petra Rita; Fogorvostudományi Kar::Parodontológiai nem önálló TanszékPeriodontitis is a worldwide disease that is caused by bacterial infection and inflammation, which damage both soft and hard tissue. Previously, diagnosis was given after the periodontal examination plus radiological examination, but recent research has found the importance of fluid peptides in the diagnosis, prognosis and management of the disease. There are some new techniques applied to this principle, such as POC, personalized medicine, and proteomic analysis. But there are still some challenges that should be overcame.Tétel Korlátozottan hozzáférhető Minimal invasive tissue preparation in periodontal surgeryJi, Yitong; Angyal, János; Debreceni Egyetem::Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Hernádi, Katinka; Tóth, Petra Rita; Debreceni Egyetem::Fogorvostudományi Kar; Debreceni Egyetem::Fogorvostudományi KarMinimally invasive surgery has been popular in medicine and dentistry, because of improvements in visualization technology. Due to the anatomical configuration of loss of bone and root structure, it is necessary to do surgical intervention to debridement root. Minimally invasive surgery with the improvement videoscope, even with relatively small incisions, nearly all areas of the root surfaces can be seen and reached, furthermore areas of calculus can be seen that are normally impossible to see with other methods of visualization. The modern minimally invasive surgical methods are highly suited to many regeneration approaches: the biologic agent such as EMD are easily placed through small access opening.periodontal surgical methods will advance to become more effective and minimally invasive.Tétel Korlátozottan hozzáférhető The effect of chemo/radiotherapy on oral health and dental development in childhoodLuay Bassam Ammari, Tala; Nemes, Judit Ágnes; Debreceni Egyetem::Fogorvostudományi Kar::Gyermekfogászati és Prevenciós nem önálló Tanszék; DE--Fogorvostudományi KarThe present thesis aimed to investigate the effects of chemotherapy and radiotherapy on oral health and dental development in children. A systematic review of the literature was conducted to identify relevant studies that met the criteria. The results of the review indicated that chemotherapy and radiotherapy have significant negative effects on oral health and dental development in childhood. Dental developmental disturbances were found in the form of tooth agenesis, morphological disturbances and enamel hypoplasia. Oral mucositis was a common complication of chemotherapy, which can result in pain and ulceration in the mouth, leading to difficulty eating and drinking. Furthermore, cancer patients who receive radiotherapy to the head and neck region are at an increased risk of developing caries and periodontal disease. Dentists and oncologists should work together to develop comprehensive oral care plans to minimize the negative effects of cancer treatments. Early identification and treatment of dental developmental disturbances, as well as preventative measures for caries, should be incorporated into the overall cancer treatment plan to improve the quality of life for pediatric cancer patients.Tétel Korlátozottan hozzáférhető Soft tissue complications of tooth removalAbdelwahab, Mai; Kalas , Nándor; Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Kunka, árpád; Taskó, Mate Sk.; Fogorvostudományi KarInjuries to the soft tissues within the oral cavity commonly involve damage to the oral mucosa or occur at the transition points between the external and internal oral regions, such as the lips. In oral surgery, ensuring the prevention and proper management of soft tissue injuries during tooth extraction is pivotal. This requires careful attention and proficiency from dental professionals. These injuries can occur due to various factors including the extraction technique, anatomical factors, and individual patient or operator-related variables. Therefore, it's essential to effectively address and avoid these injuries to optimize patient outcomes and minimize post-surgery complications.Tétel Korlátozottan hozzáférhető OsteoradionecrosisGovias, Lynelle Celia Eva; Hegedüs, Nándor; Fogorvostudományi Kar::Dentoalveoláris Sebészeti nem önálló Tanszék; DE--Fogorvostudományi Kar; Szepesi, Márta; Taskó, Máté; Fogorvostudományi Kar::Dentoalveoláris Sebészeti nem önálló TanszékOsteoradionecrosis (ORN) is a relatively rare but serious and chronic complication of radiation therapy that is used in the treatment of cancer. It manifests as irradiated bone becoming necrotic, forming a chronic unhealing wound. ORN can have dire consequences on the quality of the life of the person who suffers from it. ORN can theoretically occur in irradiated bone throughout the body, but the most reported and researched area is in the mandible. Once ORN is recognized, it is irreversible and difficult to treat, hence preventive measures should be implemented strictly, especially since its risk factors are well known. Dentists together with other multidisciplinary health care professionals play a critical role in the diagnosis, treatment and prevention of ORN in the jaws.Tétel Korlátozottan hozzáférhető Fotopolimerizálható hialuronsav hidrogél/ béta-trikálcium foszfáttal módosított aerogél kompozitok szintézise és jellemzéseAdel, Seyes Amir Reza; Rente, Tünde; Biomaterials and Prosthetic Dentistry; DE--Fogorvostudományi Kar; Debreceni Egyetem::Fogorvostudományi KarThe biomaterial scaffold is one of the most significant element in the subject of tissue engineering. This study may be providing an exhaustive synopsis of the main aspects of HA-AEMA-aerogel plus β-TCP. The characterizations of composites were performing with the analysis of mechanical properties, namely compressive strain, Young's modulus, swelling ability, structure and elemental analysis with a help of SEM and EDS.

Furthermore, the bond between dentin and DBA slowly matures, and dentin bond strength increases.Application of IDS comforts patients during the provisional phase and limits local anesthesia use during permanent restoration placement and Reduces postoperative sensitivity.Tétel Korlátozottan hozzáférhető A szájüregi daganatok és a diabetes mellitus kapcsolataStercel, Otilia; Horváth, Dóra; Arc- Állcsont- és Szájsebészet; DE--Fogorvostudományi Kar; Szabó, AdriennJelenleg a cukorbetegség globális problémának mondható, hiszen körülbelül 422 millió embert érint a Földön [40]. Közülük kevesen vannak tisztában a betegség hosszútávú következményeivel vagy a vele összefüggő egyéb betegségekkel. Ezek közé tartoznak egyes kardiovaszkuláris megbetegedések, a diabeteses nephropathia és neuropathia, a látás romlása és az egyes fertőzésekre való megnövekedett hajlam. Újabb kutatások összefüggésbe hozták rosszindulatú daganatos állapotokkal is. Számos tanulmány áll a rendelkezésünkre, amely bizonyítja az összefüggést a diabétes mellitus és a malignus elváltozások között.Tétel Korlátozottan hozzáférhető Access cavity in the 21th centuryHadieh, Ghamari; Suta, Péter; Debreceni Egyetem::Fogorvostudományi Kar::Konzerváló Fogászati Tanszék; DE--Fogorvostudományi Kar; Nagy, László; Bohács, JuditIn this study we understand what is the access cavity preparations and the error that might occur during this procedure. We also review the uptodate access cavity preparation methods. Inadequate access preparation can lead to a host of subsequent treatment issues and cause failure in the worst-case situation. Therefore, the implementation of minimally invasive dentistry is significant. Because it assists in the maximum preservation of the healthy dental issues of the patients and can prevent the common dental issues with the traditional dental access cavity preparations.Tétel Korlátozottan hozzáférhető Dental Implant FailureJassim, Ahmed; D. Tóth, Etelka; Debreceni Egyetem::Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Farkas, Georgina; Lukács, Levente; Debreceni Egyetem::Fogorvostudományi Kar::Arc- Állcsont- és Szájsebészeti TanszékDental implant therapy has swiftly become one of the most reliable and desired solutions to various kinds of edentulism. However, implants have the potential to fail for a plethora of reasons. Exploring and evaluating the risk factors of failure can assist clinicians in performing this work to a greater degree of success.Tétel Korlátozottan hozzáférhető COVID-19 Infection Prevention and Control in Dental PracticeCheruvu, Lalitha; Antal, Zsuzsa; Department of Operative Dentistry and Endodontics; DE--Fogorvostudományi Kar; Sipos, Kitti; Marincsák, Rita; Debreceni Egyetem::Fogorvostudományi KarMy thesis aims to highlight and critically analyse the current literature on COVID-19 infection prevention in dental clinics. Dentistry is a high-risk medical specialisation in which coronavirus could easily spread because we are in close contact with patients, dental teams and use procedures that generate aerosol, and there’s the nosocomial spread of the virus. COVID-19 will continue to influence and affect how dentists will practice for the foreseeable future, therefore it is important to understand the gravity of the ever-changing situation and adapt necessarily.Tétel Korlátozottan hozzáférhető Restoration of endodontically treated teethTadayyon Tahmasbi, Taraneh; Martos, Renáta; Debreceni Egyetem::Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Vilmos, Zolnai; Marincsák, Rita; Debreceni Egyetem::Fogorvostudományi Karrestoration of endodontically treated teeth is very important in prognosis of the treatment. in this thesis I described the special features of endodontically treated teeth and the options to restore them. additional retentive elements and crown coverage options were also mentioned. different materials for building up the core were described in details. and a short predict of the future of these field was also mentioned in chapter summary.
