Dental Tissue Small Extracellular Vesicles
Extracellular vesicles (EVs) are membrane-bound bilayered lipid particles that are secreted from both prokaryotic and eukaryotic cells, carrying a cargo of biological molecules (i.e., protein, nucleic acid, lipids and metabolites) from their parent cells. Dental tissue-derived (or stem) cells have remarkable characteristics for therapeutic application, being easily accessible and a rich source of stem cells with a well-known regenerative capacity. A great variety of multipotent adult or postnatal stem cells can be retrieved from dental tissues, especially from periodontal tissue and dental pulp from extracted permanent teeth (dental pulp stem cells—DPSCs) and exfoliated deciduous teeth (SHED). Stem cells can be obtained from dental apical papilla tissues (SCAP) and dental follicles (DFSCs, or DFCs) of the developing tooth. Importantly, EV that is derived from these cells can be detected within periodontal tissues and biofluid (i.e., gingival crevicular fluid).

Additively Manufactured Polylactic Acid in Dentistry
Additive manufacturing (AM), which is also called rapid prototyping/3D printing/layered manufacturing, can be considered as a rapid conversion between digital and physical models. One of the most used materials in AM is polylactic acid (PLA), which has advantageous material properties such as biocompatibility, biodegradability, and nontoxicity. For many medical applications, it is considered as a leading biomaterial. In dentistry, in addition to its uses in dental models (education, teaching, simulation needs), it can be used for therapeutic objectives and tissue engineering.

Amelioration Strategies for Silver Diamine Fluoride
Topical cariostatic agents have become a reasonable alternative for managing dental caries in young children. Silver diamine fluoride (SDF) is a practical topical approach to arrest caries and avoid extensive and risky dental treatment. The rapid oxidation of ionic silver darkens demineralised tooth structure permanently. In this regard, nano-metallic antimicrobials could augment or substitute for silver, and thereby enhance SDF aesthetic performance.

Biomimetic 3D Scaffolds to Reproduce Periodontal Ligament Microenvironment
The periodontium is a complex system composed of gingiva, periodontal ligament (PDL), cementum, and alveolar bone, featuring a hierarchically compartmentalized architecture. The homeostasis of this system is maintained by the PDL, a specialized connective tissue, which is located between the cementum and alveolar bone and articulates (gomphosis) the teeth to the jaws. Embryologically, PDL derives from the dental follicle cells under the guidance of Hertwig’s epithelial root sheath (HERS), which secrete numerous epithelium-derived factors before obliterating almost completely.

Biomimetic Implant Surfaces
The increased use of dental implants in oral rehabilitation has been followed by the development of new biomaterials as well as improvements in the performance of biomaterials already in use inspired by the properties of the tissues to be replaced. An implant is considered osseointegrated when there is no relative movement between the implant and the bone and no symptoms under a loading force. It is now known that surface topography is one of the key biomimetic factors that can directly affect the proliferation, structure, and alignment of human cells and their function and is also considered to be a critical determinant of cell adhesion.

Effects of Prosthetic Restorative Biomaterials on the Periodontium
The success of a prosthetic treatment is closely related to the periodontal health of the individual. The periodontium constitutes the tissues that support the teeth. It is made up of two soft tissues (which are the gingiva and periodontal ligament) and two hard tissues (which are the root cementum and alveolar bone).

Outcomes of Titanium and Zirconia Implant Abutments
The characteristics of the implant prosthetic abutment are an influential factor which may impact early bone remodeling and soft tissue integration. The abutment material influences the response of both the soft and hard tissues surrounding an implant, making the choice of the prosthetic abutment a crucial phase for the success of implant-supported rehabilitations.

Periodontal Diseases
Periodontal diseases, in the light of the new classification, have been divided into three general categories: gum disease, periodontitis, and other conditions affecting the periodontium.

Endotoxin-Secreting Bacteria in Periodontal Disease
The LPS is recognized by the complex TLR4/MD2, mediated by CD14 and accessory protein LBP, which induces the activation of several transcriptional regulators like factor nuclear kB (NF-kB), activator protein 1 (AP-1) and interferon (IFN) regulatory factors, leading to the expression of genes involved in the host immune response.

Implant Fracture
Implants fracture is a rare but possible complication that leads to implants failure after prostheses delivery. Fracture involves the forced separation of the implant neck into two or more parts. Mechanical properties play a key role in the failure of dental implant systems.
