Objective: It is hypothesized that the way nano- and micro-hybrid polymer-based composites are structured and cured impacts the way they respond to aging.
Material And Methods: A polymer-ceramic interpenetrating network composite (Vita Enamic/VE), an industrially polymerized (Brillinat CriosST/BC), and an in situ light-cured composite with discrete inorganic fillers (Admira Fusion5/AF5) were selected. Specimens (308) were either cut from CAD/CAM blocks (VE/BC) or condensed and cured in white polyoxymethylene molds (AF5) and subjected to four different aging conditions ( = 22): (a) 24 h storage in distilled water at 37 °C; (b) 24 h storage in distilled water at 37 °C followed by thermal cycling for 10,000 cycles 5/55 °C (TC); (c) TC followed by storage in a 75% ethanol-water solution; and (d) TC followed by a 3-week demineralization/remineralization cycling.

Body piercing has become popular among people of all ages, inspired by religious convictions, personal aesthetics, and cultural influences. Piercings in the oral cavity frequently involve the lip, buccal mucosa, frenulum, and tongue with needles, hooks, and rings. However, these piercings might cause long-term problems to both the hard and soft tissues of the mouth.

Periodontitis, a widespread inflammatory disease, is the major cause of tooth loss in adults. While mechanical periodontal therapy benefits the periodontal disease treatment, adjunctive periodontal therapy is also necessary. Topically applied anti-inflammatory agents have gained considerable attention in periodontitis therapy.

Chronic hard-to-heal wounds pose a significant threat to patients' health and quality of life, and their clinical management remains a challenge. Adipose-derived stem cell exosomes (ADSC-exos) have shown promising results in promoting diabetic wound healing. However, effectively enhancing the retention of exosomes in wounds for treatment remains a key issue that needs to be addressed.

Inherited prion diseases (IPD) secondary to mutations of the prion protein gene, exhibit diverse clinical phenotypes, capable of mimicking numerous primary neurodegenerative conditions. We describe the clinical phenotype and neuropathological findings in a family from County Limerick in Ireland presenting with Alzheimer's disease-like cognitive decline and motor symptoms caused by a novel missense mutation of This mutation occurs in the central lysine cluster (CLC; codon 101-110), resulting in substitution of threonine with isoleucine at codon 107 (T107I). This case series highlights that IPD can be hard to distinguish from overlapping clinical syndromes seen in other neurodegenerative diseases.
