Periodontal disease affects a large percentage of the human population. Resorption of the alveolar bone of the jaw is a pivotal sequela of periodontal disease, because this bone is the attachment site for the periodontal ligaments that anchor the teeth. Using a murine model in which alveolar bone loss is induced by oral infection with Porphyromonas gingivalis, a gram-negative bacterium associat...
Bio-hybrid artificial organs are an attractive concept to restore organ function through precise biological cooperation with surrounding tissues in vivo. However, in bio-hybrid artificial organs, an artificial organ with fibrous connective tissues, including muscles, tendons and ligaments, has not been developed. Here, we have enveloped with embryonic dental follicle tissue around a HA-coated d...
statement of the problem : fixed retainers were developed to maintain incisor alignments after orthodontic treatments. although the effects of fixed retainers on periodontal health are clinically studied, no studies have still evaluated the histological changes in the periodontium after the placement of thefixed retainers. purpose: the aim of this study was to evaluate the effects of customised...
The aim of this study is to investigate substance P (SP) expression in rat periodontal alveolar bone after inferior alveolar nerve transection. 60 male Wistar rats were divided into six groups randomly. Mandibular alveolar bones were removed from the denervated rats according to sacrifice time points (0, 3, 7, 14, 21, and 28 days after operation). Immunohistochemical staining was applied to tra...
Introduction: During the last decade, advances in tissue engineering and stem cell-based tooth regeneration have provided realistic and attractive means of replacing lost or damaged teeth. The first adult stem cells isolated from dental tissues were dental pulp stem cells (DPSCs). When transplanted with hydroxyl apatite/tri calcium phosphate (HA/TCP) powder, they formed a dentin-like structure...
Periodontitis is one of the most common conditions affecting oral health among adults, posing a great challenge for both patients and also dentists aiming to treat this disease. In severe stages such deterioration supporting tissues, namely periodontal ligaments bone, can occur, which will affect biomechanical behavior therefore longevity survival affected teeth. order be able plan subsequent r...
Brain-derived neurotrophic factor (BDNF) is a member of the neurotrophic factor family. Outside the nervous system, BDNF has been shown to be expressed in various nonneural tissues, such as periodontal ligament, dental pulp, and odontoblasts. Although a role for BDNF in periodontal regeneration has been suggested, a function for BDNF in periodontal disease has not yet been studied. The aim of t...
REZUMAT STUDIES ON THE EFFECT OF ENAMEL MATRIX DERIVATIVES ON EARLY WOUND HEALING. WHICH APPLICATIONS ARE EVIDENCE-BASED? Stefan-Ioan Stratul1, Darian Rusu1, Anton Sculean2 The goal of regenerative periodontal therapy is the reconstitution of the lost periodontal structures (i.e. the new formation of root cementum, periodontal ligament and alveolar bone). Results from basic research have pointe...
