Marine Biopolymer Alginate in Endodontics
Alginate is a natural marine biopolymer that has been widely used in biomedical applications, but research on its use as an endodontic material is still sparse in the literature. Alginate or salt of alginic acid is one of the most abundant biopolymeric hydrocolloids derived primarily from seaweeds. In dentistry, hydrocolloid alginate has been commonly employed as a dental impression material to make gypsum casts for various treatment purposes, including provisional crowns and bridges, orthodontic study models, mouth guards, bleaching trays, and removable dental prostheses.

Mandibular Leeway Space of Taiwanese Children
Leeway space, the most crucial space for the alignment of permanent teeth, is the difference between the sum of the mesiodistal crown widths of the primary canines and molars and that of their successors, the permanent canines and premolars. Primary molars have greater mesiodistal crown widths than the permanent premolars that replace them, especially the primary second molar. Leeway space has been preserved and utilized to resolve crowding, particularly by allowing the first molars to drift mesially to establish a Class I molar relationship in the late mixed dentition.

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.

Management of COVID-19-Associated Mucormycosis
The outbreak of coronavirus disease (COVID-19), which comes with several comorbidities, was declared a pandemic in early 2020 by World Health Organization (WHO). Glucocorticoids that are used in severe cases of COVID-19 as therapeutic measures may lead to opportunistic fungal infections in such patients. Mucormycosis is one of these infections and mostly occurs in immune-compromised patients such as those who undergo transplant surgeries.

Magnification of Iris in Ocular Prosthesis
The ocular prostheses, used for the prosthetic rehabilitation of ocular defects, are generally made from acrylic resin. As the thickness of clear acrylic over the iris is increased on the ocular prosthesis, the size of the iris is also increased, due to magnification through the clear resin.

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.

Lymphatic Vessels in the Dental Pulp
It is debatable whether lymphatic vessels exist in the dental pulp. Most researchers confirm their presence; however, the lymphatic system in the dental pulp is much less developed compared to other tissues of the body. Lymphangiogenesis occurs in the dental pulp with inflammatory changes as a response to inflammatory stimuli acting on the tooth. If lymphangiogenesis is defined as the development of lymphatic vessels from already existing ones, such a mechanism is possible only when lymphatic vessels are present in healthy teeth.

Luteolin in Prevention and Treatment of Periodontal Disease
Polyphenols, a class of flavonoids, are secondary metabolites that play a crucial role in plant adaptation to both biotic and abiotic environments, including UV radiation, high light intensity, low/high temperatures, and attacks from pathogens, among others.

Local and Systemic Effects of Porphyromonas gingivalis Infection
Porphyromonas gingivalis, a gram-negative anaerobe, is a leading etiological agent in periodontitis. This infectious pathogen can induce a dysbiotic, proinflammatory state within the oral cavity by disrupting commensal interactions between the host and oral microbiota. It is advantageous for P. gingivalis to avoid complete host immunosuppression, as inflammation-induced tissue damage provides essential nutrients necessary for robust bacterial proliferation. When it gains access to circulation, P. gingivalis is able to infect a variety of cells, further triggering a variety of inflammatory and hemostatic responses. Among these is the activation of platelets and neutrophils. Neutrophil responses to P. gingivalis, particularly in the presence of activated platelets, include the release of strongly thrombogenic extracellular DNA traps (NETs). Consequently, this pathogen has the capacity not only to promote localized tissue destructiion of the gums but may also trigger some thromboinflammatory processes.
