Medication-Induced Dry Mouth
Dry mouth is common among older people, affecting between 20% and 30% of those over 65. There are two aspects to the condition. Salivary gland hypofunction (SGH) is the state of having low salivary flow, while xerostomia refers to the subjective sensation of dry mouth.

Periodontitis in Systemic Sclerosis
Systemic sclerosis (SSc) is a chronic, autoimmune, multisystemic disease characterized by aberrant extracellular matrix protein deposition and extreme progressive microvasculopathy. These processes lead to damage within the skin, lungs, or gastrointestinal tract, but also to facial changes with physiognomic and functional alterations, and dental and periodontal lesions. Orofacial manifestations are common in SSc but are frequently overshadowed by systemic complications. In clinical practice, oral manifestations of SSc are suboptimally addressed, while their management is not included in the general treatment recommendations. Periodontitis is associated with autoimmune-mediated systemic diseases, including systemic sclerosis. In periodontitis, the microbial subgingival biofilm induces host-mediated inflammation with subsequent tissue damage, periodontal attachment, and bone loss. When these diseases coexist, patients experience additive damage, increasing malnutrition, and morbidity.

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.

Role of Oral Microbiome on Oral Cancer
Oral cancer (OC) is the most common neoplasm in the head and neck region. OCs are defined as cancers of the tongue, the floor of the oral cavity, the lining of the cheeks, the roof of the oral cavity, the gums, and the lips but do not include laryngeal and pharyngeal cancers. The majority of OCs comprise oral squamous cell carcinomas (OSCCs). The oral microbiome hosts more than 750 common oral species. A healthy microbiome usually consists of Streptococci, Staphylococci, Neisseria species, and about 50 other aerobes. The consensus is that a normal mouth microbiome consists mainly of aerobes, while the percentage of anaerobes increases with OC (and other pathological oral conditions). The connection that exists between microbes and carcinoma is complex and influenced by a number of factors, such as the vulnerability and genetic makeup of the host, as well as environmental conditions, including the host’s dietary regime, oral hygiene, and tobacco and alcohol use.

Primary Care for Oral Health
The International Dental Federation (IDF) defines oral health as “multi-faceted and included the ability to speak, smile, smell, taste, touch, chew, swallow and convey a range of emotions through facial expressions with confidence and without pain, discomfort, and craniofacial complex diseases”. The IDF definition integrates oral health with general health, demonstrating that it affects overall health and well-being. Therefore, increasing awareness about the different dimensions of oral health and how they change over time empowers people by recognizing that values, perceptions, and expectations influence its outcomes.

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.

Stem Cell Transplantation/Cell-Free Treatment for Periodontal Regeneration
Many in vivo and in vitro studies have demonstrated the efficacy of stem cell transplantation for the regeneration of periodontal tissues over the past 20 years. Although positive evidence has accumulated regarding periodontal regeneration using stem cells, the exact mechanism of tissue regeneration is still largely unknown.

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.

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.

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.

Dental Implants in AUBB and ALBBs
The Implant survival rates were negatively affected in sub-entities linked to more extensive augmentation procedures such as bone donor site and dentition status. The inclusion and pooling of literature with a low level of evidence, the absence of randomized controlled clinical trials (RCTs) comparing AUBB and ALBB and the limited count of comparative studies with short follow-ups increases the risk of bias and complicates data interpretation.

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.
