Functions of Astrocytes after a Brain Disease
Neurons and glia (astrocytes, radial glia, oligodendroglia, and microglia) are the neural cells of the central nervous system (CNS). Glial cells have different functions; microglia are the resident macrophages in the CNS, oligodendrocytes are responsible for myelin production, NG2-positive glia is consistent with an oligodendrocyte progenitor function, and astrocytes play an important role both in homeostasis and in diseases.

Oral Manifestations of COVID-19 in Hospitalized Patients
The oral cavity represents a target of SARS-CoV-2, and oral lesions are observed in both non-hospitalized and hospitalized patients. Oral ulcers, cheilitis, and tongue lesions were more common in patients before hospitalization, while perioral pressure ulcers, macroglossia, blisters, and oral candidiasis were more recurrent in patients during hospitalization.  An accurate oral examination during the hospital admission of all confirmed COVID-19 cases is encouraged to recognize oral early manifestations and to apply appropriate treatments.

Vitamin D in Oral Diseases Development
Vitamin D is a fat-soluble secosteroid that plays a significant role in the whole body, including the maxillofacial region. The discovery of its receptors in many cells and organs made it possible to reveal the participation of vitamin D not only in the regulation of calcium phosphate metabolism, but also in immune processes, in providing anti-inflammatory and antimicrobial effects, slowing down cell proliferation and stimulating differentiation. In this literature review, we demonstrate the association between low vitamin D levels and the development of recurrent aphthous stomatitis, the course and response to treatment of squamous cell carcinoma of the oral cavity, the severity of periodontal diseases, and the processes of osseointegration and bone remodeling during dental implantation and guided tissue regeneration.

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.

Sedatives in Dental Implant Surgery
Implant surgery is a lengthy dental procedure, and sedation is often used to reduce discomfort. The effectiveness of sedation has traditionally been evaluated in terms of patient and surgeon satisfaction, but the most important goal is not to induce a deep sleep in the patient, but rather to ensure that the surgery is performed safely and as planned. Additionally, adequate pain control is a necessary requirement for patient and surgeon satisfaction. Most patients undergoing implant surgery are middle-aged or older, and a relatively large number of them have cardiovascular disease. Infiltration anesthesia using articaine or lidocaine in combination with adrenaline is widely used, but its use in patients with cardiovascular disease is limited because of adrenaline’s effects on the cardiovascular system. The use of long-acting local anesthetics and the potential efficacy of ultrasound-guided jaw nerve block have been investigated to enhance analgesia without resorting to adrenaline. Midazolam and propofol are usually used for sedation, but dexmedetomidine, which causes less respiratory depression, and the ultrashort-acting benzodiazepine remimazolam are emerging as potential alternatives. Monitoring of anesthetic depth using electroencephalography is effective in maintaining a constant level of sedation. In addition, sedation promotes the stabilization of heart rate and blood pressure, reducing the risks associated with adrenaline and allowing for safer management.

Technologies for Dentin Caries Detection
To enable conservative caries management, it is imperative that caries are detected at a non-cavitated stage. Non-cavitated caries lesions (NCCLs) have the surface of enamel still intact but in depth they can reach the enamel or dentin level. The shortcomings of traditional visual and radiographic methods to detect NCCLs highlight the need for further investigation of alternative methods for caries detection.

CAD/CAM Denture Base Materials
The data about bond strength between digitally produced denture base resins and artificial teeth are scarce. No statistical differences between heat-polymerized and CAD/CAM (milled) denture base materials when attached with different types of artificial teeth, while one study showed higher values of CAD/CAM (milled) denture base materials. Bonding agents ensure bonding strength at least similar to the conventional methods. In order to improve the quality of future studies, it would be advantageous to use a larger number of specimens with standardized dimensions and a blinded testing machine operator to decrease the risk of bias.

MMPs and MMP-8 in Periodontal Diseases
Matrix metalloproteinases (MMPs) are a large family of Ca2+ and Zn2+ dependent proteolytic enzymes, able to cleave the various components of the extracellular matrix (ECM), as well as a range of other regulatory molecules. It has proven the important role of both MMPs and their endogenous inhibitors, tissue inhibitors of metalloproteinases (TIMPs), in oral health, the initial development of the tooth, and during enamel maturation.

CAD/CAM Abutments versus Stock Abutments
CAD/CAM abutments allow individualization of abutment parameters with respect to soft tissue, allow increased fracture toughness, predict the failure mode, show no change in the fracture toughness over time, reduce the prosthetic steps, and reduce the functional implant prosthesis score and pain perceived by patients in the early stages. The advantages associated with the use of stock abutments mainly concern the risk of corrosion, time spent, cost, and fit, evaluated in vitro, in the implant–abutment connection. Equal conditions are present regarding the mechanical characteristics during dynamic cycles, screw loss, radiographic fit, and degree of micromotion.

Oral Candidosis
Oral candidosis is the most common fungal infection that frequently occurs in patients debilitated by other diseases or conditions. No candidosis happens without a cause; hence oral candidosis has been branded as a disease of the diseased. Prior research has identified oral candidosis as a mark of systemic diseases, such as hematinic deficiency, diabetes mellitus, leukopenia, HIV/AIDS, malignancies, and carbohydrate-rich diet, drugs, or immunosuppressive conditions. An array of interaction between Candida and the host is dynamic and complex. Candida exhibits multifaceted strategies for growth, proliferation, evasion of host defenses, and survival within the host to induce fungal infection.

Regenerative Materials in Furcations of Patients with Periodontitis
Periodontitis is a chronic, multi-factorial inflammatory disease, caused by an inflammatory reaction by the host to a dysbiotic subgingival microflora, which can be modified by genetic and lifestyle factors, and it results in the loss of tooth-supporting apparatus, the connective tissue attachment and alveolar bone. Worldwide, periodontitis affects about 20–50% of the global population. Regeneration of lost tissues around the teeth remains a clinical challenge, especially in furcation defects of molar teeth. This research will give an overview of the outcomes of the use of different regenerative materials in the treatment of class II furcation defects in patients with periodontitis.

Photobiomodulation in Management of Temporomandibular Joint Pain
Temporomandibular joint (TMJ) pain is the third most prevalent chronic pain condition worldwide after tension headache and backbone. The TMJ’s position and structure make it an intersection of information and influences that expand throughout the body. Therefore, joint injury generally affects systemic health and leads to serious symptoms and disorders known as temporomandibular disorders (TMDs). Photobiomodulation (PBM) is an effective tool in alleviating TMDs’ pain and increasing the range of movement in patients with Axis 1 of TMDs. However, TMDs’ pain related to underlying pathology cannot be solely treated by PBM. The causative factors must be treated first.

Gastrodin for Osteoporosis Treatment
Gastrodin, a traditional Chinese medicine ingredient, is widely used to treat vascular and neurological diseases. However, recently, an increasing number of studies have shown that gastrodin has anti-osteoporosis effects, and its mechanisms of action include its antioxidant effect, anti-inflammatory effect, and anti-apoptotic effect. In addition, gastrodin has many unique advantages in promoting bone healing in tissue engineering, such as inducing high hydrophilicity in the material surface, its anti-inflammatory effect, and pro-vascular regeneration.  Gastrodin promotes the viability and osteogenic differentiation of osteoprogenitor cells, preosteoblasts, and periodontal stem cells, and inhibits osteoclast differentiation, thereby improving bone formation and reducing bone loss.

Candida in Oral Malignancy
Candida albicans is a commensal fungal species that commonly colonizes the human body, but it is also a pervasive opportunistic pathogen in patients with malignant diseases. A growing body of evidence suggests that this fungus is not only coincidental in oncology patients, but may also play an active role in the development of cancer. More specifically, several studies have investigated the potential association between C. albicans and various types of cancer, including oral, esophageal, and colorectal cancer, with a possible role of this species in skin cancer as well. The proposed mechanisms include the production of carcinogenic metabolites, modulation of the immune response, changes in cell morphology, microbiome alterations, biofilm production, the activation of oncogenic signaling pathways, and the induction of chronic inflammation. These mechanisms may act together or independently to promote cancer development.
