Improving Consistency of Photobiomodulation Therapy
One of the molecular mechanisms for this treatment implicates the mitochondrial enzyme, cytochrome C oxidase. However, the efficacy and consistency of clinical outcomes with photobiomodulation treatments has been fiercely debated. This work was motivated by this need to improve photobiomodulation devices and delivery approaches.

Prevention and Treatment of Oral Complications
Phase I, before initiation of cancer treatment (review of medical record and oral history, planning of preventive strategies and dental treatments); phase II, from initiation of chemo-radiotherapy to 30–45 days post-therapy (maintenance of oral hygiene, reinforcement of parent/patient education in oral care, prevention and treatment of complications derived from cancer treatment); phase III, from 1 year to lifetime (periodic check-ups, maintenance, and reinforcement of oral hygiene, dental treatments, symptomatic care of the effects of long-term cancer treatment). The use of standardised protocols can avoid or minimise oral cancer complications and the side effects of cancer therapies.

Magnesium Modified β-Tricalcium Phosphate
Researchers already improved the properties of β-TCP by achieving optimum surface and bulk β-TCP chemical/physical properties through the hydrothermal addition of magnesium (Mg) and to later establish the biocompatibility of β-TCP/Mg for bone grafting and tissue engineering treatments. The present results indicate that the hydrothermal addition of 1.4 wt% MgO to the particle surface of β- TCP particle significantly increased cell proliferation and osteoblastic differentiation in vitro and resulted in more new bone regeneration from histologic and micro-CT evaluation in vivo compared to the β-TCP control particles; altogether, Mg was advantageous to commercial β-TCP bone regeneration.

Topical Agents for Nonrestorative Management of Dental Erosion
A nonrestorative approach to the management of dental erosion is the foremost option: controlling dental erosion. Nonrestorative approaches to dental erosion commonly include dietary analysis and counselling, oral health education and topical use of anti-erosive agents. Topical anti-erosive agents can be broadly categorised as fluorides, calcium phosphate-based agents, organic compounds and other anti-erosive agents. In the presence of saliva, fluorides promote the formation of fluorapatite on teeth through remineralisation.

Bisphosphonates and Their Influence on the Implant Failure
The use of bisphosphonate (BP) may impair the osseointegration. It is a class of drugs that are frequently selected when there is an alteration in the bone metabolism, which are utilized to prevent bone loss. It can be administered orally (e.g., daily, weekly, or monthly) for treatment of osteoporosis and Paget’s disease, or intravenously (every 3 months or annually) to treat malignant skeletal oncological diseases.

Non-Coding RNA Transcriptome
Non-coding RNAs (ncRNAs) represent a research hotspot by playing a key role in epigenetic and transcriptional regulation of diverse biological functions. Due to their involvement in DNA translational control, their regulation of mRNA and protein expression levels and their ability to reprogram cellular signaling pathways in oral inflammatory diseases, ncRNA could be used to diagnose and predict disease and to improve patient-tailored treatments, as integral part of precision medicine for oral inflammatory diseases.

Oral Health Status in Inflammatory Bowel Diseases Patients
Inflammatory bowel diseases (IBD) are chronic disorders that affect the gastrointestinal tract, including the oral cavity. Both Crohn’s disease (CD) and ulcerative colitis (UC) patients have an increased odds of periodontitis coincidence compared to the controls. Moreover, in most studies, patients with IBD are characterized by higher values of caries indices. In conclusion, the risk of oral diseases in IBD patients cannot be clearly established due to the possible association of other factors, e.g., sociodemographic or environmental factors.

Antisclerostin Effect on Osseointegration and Bone
Sclerostin is a glycoprotein encoded in humans by the SOST gene. It is located on chromosome 17q12-q21, with a C-terminal cysteine knot-like (CTCK) domain. It has a similar sequence also to DAN (Differential screening-selected gene Aberrative in Neuroblastoma), an antagonist’s family of the bone morphogenetic protein (BMP). Sclerostin is primarily produced and secreted by osteocytes. Moreover, it is a negative key regulator of osteoblastic functions. It inhibits osteoblast differentiation and bone formation by inhibiting the Wnt signaling pathway after binding with LRP5 and 6 (Wnt-coreceptor). This canonical Wnt signaling (Wnt/β-catenin pathway) is essential in bone healing. It promotes pre-osteoblast proliferation and osteo-induction, enhances survival of all cells of the osteoblast lineage, inhibits differentiation of mesenchymal stem cells (MSCs) into chondrocytes and adipocytes and controls osteoclast maturation by regulating RANKL levels in osteoblast receptors.

Peri-Implant Diseases
Dental implant-supported prostheses are a well-established rehabilitation treatment for partially or completely edentulous patients that restore function and esthetics while having long-term survival rates. The tissues surrounding osseointegrated dental implants are referred to as peri-implant tissues, consisting of soft and hard tissue parts. The soft tissue part forms following the placement of implant/abutment during the wound healing and is known as “peri-implant mucosa,” while the hard tissue part makes contact with the implant surface to ensure implant stability.

Oral Microbiota in Patients with Peri-Implant Disease
Peri-implant infections are the most common complications related to the placement of dental implants. There are many microbial similarities between peri-implantitis and periodontitis but due to current laboratory techniques there are just as many differences. The peri-implant microbiota presents a lower microbial quality than the periodontal microbiota, becoming increasingly complex as it progresses from peri-implant mucositis to peri-implantitis. The microbial difference detected between the peri-implant and periodontal microbiota is primarily related to whole bacterial populations, rather than specific bacterial taxa. The use of probiotics could support the reduction of peri-implant pockets, in association with mechanical debridement, due to their mechanism of action of competitive inhibition for adhesion sites. The peri-implant microbiota represents a qualitatively inferior but quantitatively superior bacterial ecosystem for some bacterial genera compared to the periodontal microbiota, showing that a progression from healthy state to peri-implantitis causes changes in microbiota composition in the absence of specific disease-causing bacteria.

Factors That Influence the Accuracy of Intraoral Scanners
Intraoral scanners (IOSs) have become increasingly popular in the field of dentistry for capturing accurate digital impressions of patients’ teeth and oral structures. The accuracy of intraoral scanning is influenced by various factors such as scanner selection, operator skill, calibration, patient’s oral anatomy, ambient conditions, and scanning aids. Maintaining updated software and understanding factors beyond scanner resolution are crucial for optimal accuracy. Conversely, smaller IOS tips, fast scanning speeds, and specific scanning patterns compromise the accuracy and precision. By understanding these factors, dental professionals can make more informed decisions and enhance the accuracy of IOSs, leading to improved final dental restorations.

Endodontic Regenerative Procedures in Necrotic Adult Teeth
Regenerative endodontic procedures (from now on REPs) have been defined as ‘biologically based procedures that intend to physiologically replace damaged tooth structures, including dentine and root, as well as cells of the pulp–dentin complex’. REPs were first exclusively developed for the treatment of immature teeth, with the purpose of achieving a complete root development. Nevertheless, these procedures can also restore tooth vitality and pulp functions thanks to the pulp tissue regeneration. Thus, sensibility, immunity, healing, and restorative properties of dental pulp would also be recovered, in turn reducing the chances of reinfection. For that reason, the feasibility of this treatment in mature teeth should be further studied, as until now, conservative treatment for irreversible necrosis or pulpitis has been limited to conventional endodontic therapy.

Mandibular Flexion on Implant-Supported Full-Arch Rehabilitations
Mandibular flexion (MF) is a complex biomechanical phenomenon, which involves a deformation of the mandible, due mainly to the contraction of the masticatory muscles, and it can have numerous clinical effects. The deformation of the lower jaw caused by mandibular flexion is generally very small, and it is often overlooked and considered irrelevant from a clinical point of view by many authors; however, it should be important to remember that median mandibular flexure (MMF) has a multifactorial aetiology.

Strength Parameters of Composite Cements and Storage Temperature
Fixed restorations are now among the most common restorations in modern dental prosthodontics. The view in prosthodontics of maximum preparation economy is causing an increased interest in the mechanical properties of cements. Among the most important properties of materials used for indirect cementation are mechanical properties, i.e., hardness and compressive strength. These properties can change as a result of changes in physical factors. Some studies indicated that mechanical properties, such as flexural strength, polymerization shrinkage, and conversion factor, did not change after heating the composite material. According to some researchers, preheating the composite material increased its conversion degree, which consequently led to an increase in hardness and fracture toughness, an increase in flexural strength and an increase in elastic modulus, and an increase in abrasion resistance.
