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.

Molecular, Cellular and Genetic Aspects of Peri-Implantitis
Peri-implantitis is a multi-factorial disease with an inflammatory background that occurs in both soft and hard tissues surrounding implants. A wide array of cells stands behind peri-implantitis, as well as cytokines and their genetic variations that take part in the process. Recently, growing interest in this topic has led to the introduction of specific new diagnostic tools to enable a better understanding of patients’ responses to treatment and, in turn, to even enable prediction of the risk of developing peri-implant disease.

The Local Neuropeptide System of Keratinocytes
The synthesis and activity of neuropeptides and their receptors in epithelial cells of the skin and mucous membranes. Note that the term "neuropeptide" was originally coined to indicate small protein molecules that are contained in neurons, however it is now known that the synthesis of this class of peptides is not restricted to neurons.

Tactile Sensibility Thresholds in Implant Prosthesis/Complete Dentures/Natural Dentition
The periodontium has important proprioceptive receptors that prevent teeth from using excessive occlusal forces during chewing. There are other receptors from adjacent tissues that replace periodontal ones when teeth are extracted and rehabilitated with prosthesis, although they seem to be less effective. Psychophysical studies investigate tactile sensibility thresholds, which are useful to measure this masticatory efficiency in different prosthetic rehabilitations. There are two types of sensibility depending on the receptors that are activated during these studies: active and passive tactile sensibility. The mean values of active tactile sensibility thresholds in complete dentures, implant prosthesis and natural dentition are 64 µ, 23.3 µ and 16.1 µ, respectively. The mean values of passive tactile sensibility thresholds in implant prosthesis and natural dentition are 6.7 N and 0.8 N, respectively. Implant prosthesis have lower thresholds, that are very close to those present in natural dentition, than complete dentures due to an increased tactile sensibility. Active tactile sensibility thresholds present fewer differences between values than passive tactile ones; as these are only influenced by receptors from periodontal or periimplant tissues.

AI Applications in Dental Diagnostics and Cephalometric Analysis
Artificial intelligence (AI) describes the ability of machines to perform tasks that are classified as intelligent. AI can be classified into two main categories: symbolic AI and machine learning (ML). Symbolic AI involves structuring an algorithm in a way that is easily understandable to humans. Machine learning (ML) is the predominant paradigm in the field of AI. The advent of artificial intelligence (AI) in medicine has transformed various medical specialties, including orthodontics. AI has shown promising results in enhancing the accuracy of diagnoses, treatment planning, and predicting treatment outcomes. Its usage in orthodontic practices worldwide has increased with the availability of various AI applications and tools.

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.

Photobiomodulation with Laser Technology in Fixed Orthodontic Treatment
Despite the growing demand for improving smile aesthetics and occlusal functionality, a significant percentage of patients still refuse or discontinue orthodontic treatment because of pain and discomfort related to this therapy. As consequence, controlling the pain experienced by patients during the same therapy represents a primary concern for both patients and clinicians. Pieces of evidence have suggested that photobiomodulation can reduce pain experienced by patients during the decrowding stage or during specific protocols, for example, rapid maxillary expansion. PBM can be performed with lasers and also with a light-emitting diode (LED) device.

Melatonin and Periodontitis-Related Systemic Diseases
Periodontitis has become the main reason for tooth loss/edentulism in adults worldwide. It is also linked closely with other systemic diseases such as cardiovascular disease, Alzheimer’s disease, diabetes, and cancer, thus profoundly impairing people’s quality of life. As the most common chronic inflammatory disease of humans, periodontitis has brought about huge socioeconomic impacts and healthcare costs. Periodontitis as a highly prevalent chronic infection/inflammatory disease can eventually lead to tooth loss and masticatory dysfunction. It also has a negative impact on general health and largely impairs quality of life. The tissue destruction during periodontitis is mainly caused by the excessive immune–inflammatory response; hence, how to modulate the host’s reaction is of profound importance for effective periodontal treatment and tissue protection. Melatonin, as an endogenous hormone exhibiting multiple biological functions such as circadian rhythm regulation, antioxidant, and anti-inflammation, has been widely used in general healthcare. The application of melatonin as an adjunctive approach in the treatment of periodontitis and periodontitis-related systemic comorbidities is witnessed.

Currently Existing Pathogenesis of Oral Lichen Planus
Lichen ruber planus (LP) is a chronic, autoimmune, inflammatory mucocutaneus disease that influences the hair, skin, and nails, as well as the genital, oesophageal, laryngeal, conjunctival, and oral mucosa. Mostly, it is isolated only in the oral cavity without involving the skin or other mucous membranes. Oral lichen planus (OLP) is considered a T cell-mediated chronic inflammatory process activated by an unknown antigen, making basal keratinocytes vulnerable to a cytotoxic cell mediated immune response.

Systemic Impact of Periodontitis
Periodontitis is a microbially driven host-mediated disease that leads to loss of periodontal attachment and bone. It is associated with elevation of systemic inflammatory markers and with the presence of systemic co-morbidities. Furthermore, periodontal treatment leads to a 24–48 h-long acute local and systemic inflammatory response.

Secretome Derived from SHED in Tissue Regeneration
Stem cells from human exfoliated deciduous teeth (SHED) have emerged as an alternative stem cell source for cell therapy and regenerative medicine because they are readily available, pose fewer ethical concerns, and have low immunogenicity and tumourigenicity. SHED offer a number of advantages over other dental stem cells, including a high proliferation rate with the potential to differentiate into multiple developmental lineages. The therapeutic effects of SHED are mediated by multiple mechanisms, including immunomodulation, angiogenesis, neurogenesis, osteogenesis, and adipogenesis. Since SHED are more potentially useful source of stem cells than BM-MSCs and DPSCs in cell therapy, therefore it could be suggested that the secretome derived from SHED could enhance tissue regeneration and repair and hence, considered as a suitable candidate for a cell-free approach in regenerative medicine and dentistry.

Lasers in Orthodontics
The orthodontics field is constantly looking for innovations to improve mechanical efficiency of tooth movement and patient's quality of life during treatment. New scientific reports on phototherapy and how it can optimize different stages of corrective treatment (before, during and after treatment) are discussed. Recurrent conditions that can be treated with lasers include removal of carious tissue, dentine hypersensitivity, and temporomandibular disorders. There is evidence that laser treatment optimize recovery, enabling the individual to start orthodontic treatment sooner. Along orthodontic interventions, photobiomodulation therapy is indicated for post-activation analgesia, repairing traumatic ulcers, and accelerating tooth movement. In addition, antimicrobial photodynamic therapy is also suitable for effective decontamination of oral infections such as herpes lesions and peri-implantitis. Finally, high-intensity lasers are a powerful ally in removing brackets and restoring the red aesthetics. The use of light sources in orthodontic routines has many advantages, including simplicity of technique, ease of handling of the appliance, minimal invasiveness, and patient comfort during the procedure. It is crucial that professionals develop a critical view of technological advances to provide safe, evidence-based treatments. Laser treatment improves the patient's experience during orthodontic treatment and minimizes side effects of clinical procedures.
