By adopting these advanced technologies, dental practices can save time, enhance patient satisfaction, and reduce costs in the long run. The methodology involved systematic digital assessments, planning, and execution to address cosmetic concerns, resulting in a successful transformation of a patient’s smile using e.max^® CAD/CAM technology and Medit i700 scanner. The case study highlights the importance of patient preference, efficiency, and accuracy in digital dentistry, demonstrating the potential for providing personalized and effective solutions for aesthetic dental concerns. Embracing digital advancements and patient-centered care is crucial for delivering high-quality and innovative solutions in modern aesthetic dentistry.

Postbiotics, representing the newest member of the family of biotics, are metabolites produced as a result of fermentation of lactic acid bacteria (LAB) in the De Man, Rogosa, and Sharpe (MRS) medium which includes proteins, sugars and minerals. The components of postbiotics includes exopolysaccharides (EPS), short-chain fatty acids (SCFAs), bacteriocins, antioxidants, and metabolizing enzymes. Several studies indicate that postbiotics have multiple properties such as antimicrobial, immunomodulatory, antioxidant, anti-inflammatory, anti-obesity, anti-diabetic, and anti-tumoral properties. Natural polysaccharides refer to the polysaccharides obtained from biological organisms including algae, plants, animals, and microorganisms. Polysaccharides are either branched or linear macromolecules and are composed of a few major and some minor monosaccharides, including glucose, fructose, mannose, arabinose, galactose, fucose, galacturonic acid, glucosamine, galactosamine or their derivatives. Similar to postbiotics, polysaccharides also exhibit anti-inflammatory, antibacterial, antitumor, antiviral, immunomodulatory, and antioxidant properties. Although polysaccharides cannot be directly digested by the human body due to the lack of specific enzymes, they can be digested by gut-residing bacteria including but not limited to LAB. Recent studies indicate that large non-starch polysaccharides such as alginate, fucoidan, chitosan, carrageenan, and guar gum can be degraded into low molecular weight oligosaccharides which in turn can provide health benefits to the human health. These new findings inspired us to propose a polysaccharides-based postbiotics, also called glycanbiotics, and their potential applications. We propose that polysaccharides can be fermented by probiotics, and subsequent removal of bacteria will increase the safety of their produced metabolites, including oligosaccharides, disaccharides, monosaccharides and their derivatives. These polysaccharides-based postbiotics may mimic metabolization of polysaccharides in vitro and consequently broaden the applications of postbiotics. Non-probiotics such as Akkermansia muciniphila and other bacteria can also be used for glycanbiotics production, thus providing novel applications for human health.

The emergence and subsequent advancement of nanotechnology in recent years have greatly benefited the healthcare sector, particularly in the treatment of cancer. As per study, major fatalities are related to the lung cancer. For many years, oral tyrosine kinase inhibitors (TKIs) against the epidermal growth factor receptor (EGFR) family of receptors have been used in the clinic to treat human malignancies, although they observed some very serious adverse effects in the treatment of lung cancer, especially in non-small cell lung cancer (NSCLC). Despite EGFR-TKIs’ exceptional qualities as small-molecule targeted medications, their applicability is nevertheless limited by their poor solubility, inconsistent oral bioavailability, high daily dose needs, high plasma albumin binding propensity, and initial/acquired drug resistance. Article’s purpose is to investigate EGFR-TKI’s effects on lung cancer and get around some of its drawbacks, nanotechnology will be an innovative strategy. An effective tool to increase the effectiveness of these pharmaceuticals is nanotechnology by methods other than oral. This article signifies that a range of nanomedicine delivery systems have been developed to effectively distribute EGFR-TKIs with improved drug release kinetics and tissue-targeting capacity. This review article intends to present information regarding lung cancer and EGFR relation, mechanism of recently approved EGFR-TKI’s targeted therapy, an updated landscape of EGFR-TKIs and their clinical status over lung cancer, advantages and disadvantages of nanotechnology, and new breakthroughs in nano-delivery which mentioned as a significantly better over traditional drug chemotherapy and delivery.
