    Nguyen, Quang Bach; Bakó, József; Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Szalóki, Melinda; Suta, Márton; Fogorvostudományi Kar
    The use of polyethylene glycol dimethacrylate (PEG-DMA) is extensive in tissue engineering due to its mechanical properties, lack of immunogenicity, recognized cytocompatibility, and ease of synthesis. In our study, PEG-DMA of 550 and 750 Da number average molecular weight polymer-based 3D printable solutions were prepared in a double photo-initiator system including riboflavin (Rb)/triethanolamine (TEA) and water-soluble diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (wsTPO). The 3D printable ink solutions and their consecutive hydrogels were investigated by rheological parameters, compressive and tensile mechanical properties, water swelling, contact angle measurement, and FTIR analysis. The results demonstrated that both PEG-DMA (Mn: 550 and 750) hydrogel systems were successfully printed using Rb/TEA and wsTPO photo-initiator system with an SLA 3D printer, making it an important form of hydrophilic polymer for biomedical applications, as well as in the field of dentistry such as surface modification, bioconjugation, drug administration, tissue engineering, and periodontal regenerative surgery. These properties of the 3D-printed hydrogels make these promising candidates for these applications in the near future.

    Hosseini, Hossein; Varga, István; Fogorvostudományi Kar::Parodontológiai nem önálló Tanszék; DE--Fogorvostudományi Kar; Hernádi, Katinka; Tóth, Petra Rita; Fogorvostudományi Kar::Parodontológiai nem önálló Tanszék
    This extensive study investigated the characteristics of pediatric periodontal disorders, including their risk factors, etiology, epidemiology, and treatment options. Due to their frequency and potential for long-term effects, such as systemic health problems, periodontal diseases—mainly gingivitis and periodontitis—present serious health risks. Plaque buildup is the main causative component in the complex etiology of periodontal disorders. Genetic predispositions and exogenous variables such as stress, dietary inadequacies, and tobacco smoking affect the severity and course of many disorders. The establishment of lifetime oral health practices is heavily influenced by the beginning and progression of periodontal diseases throughout infancy, especially in the phases of mixed dentition and adolescence.

    Mucosal vaccination against periodontal disease
    Jónsdóttir, Heidrún Huld; Varga, István; Fogorvostudományi Kar::Parodontológiai nem önálló Tanszék; DE--Fogorvostudományi Kar; Hernádi, Katinka; Angyal, János; Fogorvostudományi Kar::Parodontológiai nem önálló Tanszék
    Periodontal disease is the most common disease in the oral cavity, it is a chronic inflammatory disease, involving interaction between host cells and gram-negative anaerobic bacteria. Without proper treatment periodontal disease shows gradual tooth attachment loss and eventually leads to tooth loss. Mucosal vaccination may offer a powerful addition to the current treatment of periodontal disease, since it is able to provide systemic and mucosal immunity in the oral cavity and produce longer-lasting mucosal immune responses. A successful periodontal vaccine needs a potent antigen, a strong adjuvant, optimal route of administration and an effective formulation or delivery carrier. There are currently no periodontal vaccines available to be used in the clinics, however several successful studies with animal models have tested different antigens from P. gingivalis, F. nucleatum and A. actinomycetemcomitans as suitable vaccine targets.

    Yin, Ruohan; Varga, Istvan; Fogorvostudományi Kar::Parodontológiai nem önálló Tanszék; DE--Általános Orvostudományi Kar; Angyal, Janos; Toth, Petra Rita; Fogorvostudományi Kar::Parodontológiai nem önálló Tanszék
    Periodontitis 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.

    Association of probable bruxism with periodontal status
    Saadoon, Khadeeja Ihab Saadoon; Hernádi , Katinka; Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Varga, István; Reznik , György
    The purpose of this Thesis is to evaluate, from a periodontal perspective, the association that exists between bruxism and periodontal health. An in-depth analysis and a review of the pertinent research literature were conducted as part of this Thesis, which has as its primary objective the comprehension of the consequences of bruxism on the periodontium. Bruxism, which is characterized by the involuntary clenching, grinding, or bracing of teeth, has long been the focus of clinical attention and scientific inquiry. Psychosocial causes, genetic predisposition, drugs, occlusal interferences, trauma, and correlations with other medical disorders all contribute to its complex etiology. A thorough literature search revealed the widespread occurrence of bruxism and the damaging effects it has on the teeth, periodontium, and the temporomandibular joint (TMJ).

    Treatment options of multiple gingival recessions
    Moradbakhsh Lomer, Mohammad; Angyal, János; Fogorvostudományi Kar::Parodontológiai nem önálló Tanszék; DE--Fogorvostudományi Kar; Varga, István; Tóth, Petra Rita; Fogorvostudományi Kar::Parodontológiai nem önálló Tanszék; Fogorvostudományi Kar
    Gingival recession, the displacement of the gingival margin below the cemento-enamel junction or dental implant platform, is a pathological state caused by the degeneration of periodontal and peri-implant tissues. This condition, leading to root exposure, can result in hypersensitivity, root caries, and aesthetic issues. Treatment aims include optimal plaque control, complete root coverage, periodontal regeneration, and avoiding probing depths over 3 mm, with an emphasis on achieving ideal tissue bleeding and color. The Modified Coronally Advanced Flap (MCAF) and Modified Coronally Advanced Tunnel (MCAT) techniques, tailored to treat multiple gingival recessions based on gingival thickness, promote wound stability and tension-free flap closure. These approaches differentiate treatment based on thick and thin phenotypes, highlighting the significance of customized surgical techniques for enhanced periodontal regeneration.

    Periodontal aspects of Endodontics
    Smagulova , Diana; Suta , Peter; Fogorvostudományi Kar::Konzerváló Fogászati nem önálló Tanszék; DE--Fogorvostudományi Kar
    The topic “Periodontal aspects of Endodontics” refer to the relationship and interactions between the dental pulp, root canal system, and the surrounding periodontal tissues. The presence of anatomical and functional relationship between these two entities was demonstrated by numerous studies held on this topic. Pathogenic bacteria and other irritants may migrate from the pulp to the periodontium and vice versa through physiological communication pathways such as apical foramen, dentinal tubules and lateral canals. Such exchange of pathogens often contributes into the development of the endo-periodontal lesions. Despite the presence of direct routes permitting the transmission of bacteria, the effect of periodontal lesions on the development of pulpal diseases is still controversial for many clinicians.

    Etiology of Dental Erosion - Intrinsic Factors
    Al Hassani, Farah; Balogh, Bettina; Fogorvostudományi Kar::Konzerváló Fogászati nem önálló Tanszék; DE--Fogorvostudományi Kar; Kelentey, Barna; Nagy, László; Fogorvostudományi Kar::Konzerváló Fogászati nem önálló Tanszék; Fogorvostudományi Kar::Konzerváló Fogászati nem önálló Tanszék
    Dental erosion, influenced by intrinsic factors like saliva composition and tooth characteristics, is a complex oral health issue. The onset and course of dental erosion are significantly influenced by intrinsic factors. Enamel's strong mineralized makeup lacks regeneration, while less calcified dentin is more soluble, making both susceptible to erosion. Behavioral tendencies and systemic illnesses, such as GERD, bulimia, anorexia, diabetes, and hyperemesis gravidarum during pregnancy, accelerate acidic tooth degradation. Both the permanent and deciduous dentitions are vulnerable to erosion, requiring a multidisciplinary team involving medical physicians, dentists, and mental health specialists for accurate diagnosis and effective treatment. A comprehensive understanding of intrinsic factors is extremely crucial for developing preventive measures and tailored treatments to reduce the impact of dental erosion on overall oral health.

    Osteoradionecrosis
    Govias, 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 Tanszék
    Osteoradionecrosis (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.

    Al Bargash, Sarah; Vitalyos, Geza; Fogorvostudományi Kar::Fogszabályozási nem önálló Tanszék; DE--Fogorvostudományi Kar; Torok, Judit; Olah , Barbara; Fogorvostudományi Kar::Fogszabályozási nem önálló Tanszék
    Temporary Anchorage devices (TADs) have revolutionized orthodontics treatment methodologies, offering more precise and efficient approaches to complex malocclusions. These devices, categorized as extra-alveolar and intra-alveolar TADs, provide high stability, reduce undesired dental displacements, and improve management in intricate treatment situations. They are effective in addressing various malocclusions, rectifying skeletal irregularities, and enhancing tooth repositioning predictability. Intra-alveolar TADs, such as mini-implants or micro-implants, demonstrate remarkable adaptability and accuracy, facilitating localized anchorage within the alveolar bone. Their unique characteristics, including biocompatibility and durability, provide customized solutions for precise tooth adjustments, resulting in enhanced precision and decreased treatment duration. The clinical use of TADs spans a broad range of orthodontic complexities, addressing issues like molar distalization, space closure, open bites, deep bites, and skeletal discrepancies.

    Tumors of odontogenic origin
    Mohamadi, Yasin; Adrienn, Szabó; Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Horváth, Dóra; Robert, Boda; Fogorvostudományi Kar
    Odontogenic tumors originate from odontogenic ectomesenchymal and/or epithelial tissues, exhibiting diverse clinical behaviors and histopathologies. They can be classified as benign or malignant, with the World Health Organization (WHO) dividing them into odontogenic epithelial, ectomesenchymal, or mixed cells. Teeth development is responsible for unique lesions in jawbones, which are developed through a complex interaction between primitive ectoderm and ectomesenchymal tissues in the jawbones. The etiology of odontogenic tumors is incompletely understood, but genetic mutations, odontogenic remnants, and dental developmental abnormalities have been identified as potential contributing factors. Accurate classification and prognosis prediction rely on clinical, radiographic, histopathological, immunohistochemical, and molecular analyses. The therapeutic management of odontogenic tumors requires a tailored approach based on tumor type, size, location, and patient-specific factors. Surgical resection remains the primary treatment modality, while adjuvant therapies like radiation therapy and chemotherapy may be employed in select cases. This thesis provides a comprehensive understanding of tumors of odontogenic origin, emphasizing the importance of accurate diagnosis, appropriate classification, and personalized treatment planning to optimize patient outcomes

    Imaging in Orthodontics
    Tsai, Ping-Cheng; Török, Judit; Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Vitalyos, Geza; Hevesi, Judit; Fogorvostudományi Kar
    The thesis discusses the increasing importance of imaging in orthodontics for a comprehensive understanding of a patient's oral and facial structure. Traditional two-dimensional imagery is limited in depicting tooth and bone structure fully, justifying the significance of three-dimensional imaging. Contemporary technologies like cone beam computed tomography (CBCT) and three-dimensional facial scans provide more accurate and comprehensive images, aiding in diagnosis, treatment planning, and follow-up in orthodontic care. Three-dimensional imaging allows for early identification of issues, personalized treatment plans, and enhanced surgical precision.
