Fixed Orthodontic Appliances
Fixed orthodontic appliances consist of archwires, brackets, and ligatures. During treatment, the archwires are ligated into the slot of the bracket. The most commonly used materials from which parts of fixed appliances are manufactured are alloys of stainless steel (SS) and nickel-nitanium (NiTi) because of their advantageous mechanical properties.

Hypothetical Model of Clinical Remount Benefits Existing Dentures
The clinical remount procedure, which involves remounting the dentures on an articulator with interocclusal records, can effectively reduce occlusal discrepancies. This procedure can be applied not only to new dentures but also to those already in service. Performing a clinical remount on these existing dentures would enhance the oral function of the denture wearer and would enable effective and accurate correction of the accumulated errors in the jaw relationship in a stable working environment. The clinical remount procedure should be performed if a patient has poor masticatory function or occlusion-related complaints. This procedure remains an essential skill both for fabricating quality dentures and maintaining those already in service.

Resveratrol against Oral Squamous Cell Carcinoma
Oral squamous cell carcinoma (OSCC) is one of the most prevailing and aggressive head and neck cancers, featuring high morbidity and mortality. The available conventional treatments suffer from several adverse effects and are often inefficient in terms of their survival rates. Thus, seeking novel therapeutic agents and adjuvants is of the utmost importance for modern society. Natural polyphenolic compounds have recently emerged as promising chemopreventive and anticancer agents. Specifically, the natural compound resveratrol (RSV) has recently gained momentum for this purpose. RSV is useful for treating OSCC due to its antiproliferative, antimetastatic, and proapoptotic effects. Additionally, RSV acts against tumor cells while synergically cooperating with chemotherapeutics, overcoming drug resistance phenomena.

The Making of Surgical Guide for TADs
A temporary anchorage devices (TADs)  surgical guide is a guide that allows a dental surgeon to place TAD in a precise, pre-planned location to give the ideal depth, angulation, and screw size to fit the area for anchorage purposes. The purpose of anchorage in orthodontics is to move a tooth or teeth for dental and alveolar orthopedic purposes. The TAD number of the screw that can be placed using the surgical guide may range from one to multiple, depending on the purpose of the anchorage needed. The surgical guide is made from hard materials like acrylic or metal. The TAD surgical guide is positioned over the adjacent teeth to maintain stability during the maneuver. The surgical guide is created using CAD/CAM technology and a 3D printer.

Ozone Form of Application in Pediatric Dentistry
Ozone is a great oxidizing agent found in nature as a trivalent oxygen (O3). It is a colorless gas with a strong smell. It exists at the ground level as an air pollutant and a constituent of metropolitan smog, as well as in the Earth’s upper atmosphere, in the stratosphere, as a naturally defensive layer from ultraviolet rays. Ozone therapy is suggested in the management of deep dental caries, Early Childhood Caries (ECC), molar incisor hypo-mineralization (MIH), root canal therapy, remineralization, dental hygiene, and dental prophylaxis, in young children and uncooperative pediatric patient. The main forms of application are gaseous ozone, ozonated water and ozonated oil.

Laser-Assisted Non-Surgical Treatments of Periodontitis
This entry explores the innovative use of lasers in the non-surgical treatment of periodontitis, shedding light on the advantages, effectiveness, and limitations of this approach. There has been a massive eruption of innovations and technologies to assist in the treatment of periodontal diseases over the past 30 years. The use of lasers has opened new horizons and possibilities that can enhance periodontal treatments. However, their use is not always based on validated concepts and evidence-based protocols. Hence, this entry aims to describe, summarize, and assess the available evidence on the current laser-assisted protocols in the non-surgical treatment of periodontitis. Four distinct laser-assisted approaches are addressed: (1) the use of lasers for the removal of subgingival calculus, (2) the use of lasers in photodynamic therapy/photoactivated disinfection, (3) the use of lasers in photobiomodulation therapy, and (4) the use of high-power lasers. Based on the available studies and on the current guidelines and recommendations, the use of lasers exhibits several advantages, such as the increased disinfection of periodontal pockets and the junctional epithelium and connective tissue, the removal of calculus and biofilm, and the bactericidal effect on periodontal pathogens. Moreover, photobiomodulation therapy seems to play a positive role in the management of the inflammatory process of periodontitis. Although promising, the use of lasers in the non-surgical treatment of periodontitis needs to be further investigated.

Dec1 and Dec2
Periodontal inflammation is a common inflammatory disease associated with chronic inflammation that can ultimately lead to alveolar attachment loss and bone destruction. Understanding autophagy and pyroptosis has suggested their significant roles in inflammation. In recent years, studies of differentiated embryo-chondrocyte expressed genes 1 and 2 (Dec1 and Dec2) have shown that they play important functions in autophagy and in pyroptosis, which contribute to the onset of periodontal inflammation.

Overview of COVID-19-Associated Mucormycosis
Immune-compromised diseases lead to a majority of opportunistic conditions such as oral fungal infections, also known as oral mycosis. Often, the impairment of host resistance leads to the initiation of pathogenic conditions in the oral cavity, and progression through local colonization. The use of immunosuppressive drugs and immunodeficiency upon viral infection, especially in COVID-19 patients, has led to a significant increase in the frequency of oral mycosis globally.

Nrf2 and NLRP3 in the Field of Dentistry
The functional implications of the nuclear factor E2-related factor or nuclear factor (erythroid-derived 2)-like 2 (Nrf2), with special attention to the NACHT (nucleotide-binding oligomerization), LRR (leucine-rich repeat), and PYD (pyrin domain) domains-containing protein 3 (NLRP3) inflammasome in the field of dentistry were summarized. NLRP3 plays a crucial role in the progression of inflammatory and adaptive immune responses throughout the body. It is already known that this inflammasome is a key regulator of several systemic diseases. The initiation and activation of NLRP3 starts with the oral microbiome and its association with the pathogenesis and progression of several oral diseases, including periodontitis, periapical periodontitis, and oral squamous cell carcinoma (OSCC). Understanding the cellular and molecular biology of the NLRP3 inflammasome and its relationship to Nrf2 is necessary for the rationale when suggesting it as a potential therapeutic target for treatment and prevention of oral inflammatory and immunological disorders.

Prevalence and Features of Oral Lesions in COVID-19
Regardless of rapidly emerging findings on oral lesions described in adult SARS-CoV-2-positive subjects, the evidence level remains quite low and rather contrasting. It is well known that multiple viral pathogens, first of all, Herpes and human Papilloma viruses, are directly responsible for the genesis of benign, potentially malignant and malignant lesions of the oral mucosa, underlining the necessity to examine the potential causative role of SARS-CoV-2 in oral lesions.

Oral Papillomatosis
Oral papilloma lesions may appear as a result of HPV infection, or not, and only special molecular methods could differentiate them. Low-risk and high-risk HPV types could induce oral HPV papillomatosis with different natural evolution, clearance and persistence mechanisms. The pathogenic mechanisms are based on the crosstalk between the oral epithelial and immune cells and this very efficient virus. According to the degree of malignity, three types of papillomatous lesions can be described in the oral cavity: benign lesions, potential malign disorders and malignant lesions. The precise molecular diagnostic is important to identify the presence of various virus types and also the virus products responsible for its oncogenicity. An accurate diagnostic of oral papilloma can be established through a good knowledge of etiological and epidemiological factors, clinical examination and laboratory tests.
