This study examined the growth of 52 new dental practices established between 1985 and 1990 in the North West of England and North Wales. Growth was measured from the number of estimates (equivalent to a course of treatment) submitted by the practice to the Dental Practice Board since the practice first opened. Values ranged from less than 1000 estimates up to 12,000 estimates during the first 24 months; the modal value was between 2000 and 2999. The number of estimates was not associated with the resident population to dentist ratio for the surrounding locality.

Bone tissue engineering is a promising field that aims to rebuild the bone tissue using biomaterials, cells, and signaling molecules. Materials like natural and synthetic polymers, inorganic materials, and composite materials are used to create scaffolds that mimic the hierarchical microstructure of bone. Stem cells, particularly mesenchymal stem cells (MSCs), play a crucial role in bone tissue engineering by promoting tissue regeneration and modulating the immune response.

This study aimed to evaluate a new modified fixed appliance for rehabilitation of premature loss of anterior teeth in preschool children versus a modified Nance appliance on maxillary arch growth with parental satisfaction. The study was conducted as a clinical trial and it was carried out at Pediatric Dentistry Department, Faculty of Dentistry, Tanta University. Forty preschool children from both genders aged from 3-5 years were included in the study.

Background: Newer generation platelet concentrates, such as advanced platelet-rich fibrin plus (A-PRF+) obtained following low-speed centrifugation concept and horizontal platelet-rich fibrin (H-PRF) obtained from swing out and bucket system, showed increased platelet entrapment and growth factor release in the in-vitro studies. This prospective study aimed to evaluate and compare the clinical outcomes of A-PRF+ and H-PRF membranes in the treatment of gingival recession defects. The objectives of this study were to compare the changes in the recession height (RH) and the mean root coverage percentage (MRC%) between and within the research groups.

The upstream mechanobiological pathways that regulate the downstream mineralization rates in periodontal tissues are limitedly understood. Herein, we spatially colocalized and correlated compression and tension strain profiles with the expressions of mechanosensory ion channels (MS-ion) TRPV4 and PIEZO1, biometal zinc, mitochondrial function marker (), cell senescence indicator (), and oxygen status marker hypoxia-inducible factor-1α () in rats fed hard and soft foods. The observed zinc and related cellular homeostasis in vivo were ascertained by TRPV4 and PIEZO1 agonists and antagonists on human periodontal ligament fibroblasts ex vivo.

Background: The aging of bone marrow mesenchymal stem cells (BMSCs) impairs bone tissue regeneration, contributing to skeletal disorders. LncRNA NEAT1 is considered as a proliferative inhibitory role during cellular senescence, but the relevant mechanisms remain insufficient. This study aims to elucidate how NEAT1 regulates mitotic proteins during BMSCs aging.
