In our study, the periodontal ligament fibers
increased collagen in the diabetic group, the hemorrhage was seen as important in inflammation and vascular changes.
The authors concluded that maintaining the vitality of the cells and periodontal ligament fibers is an important factor that might affect the success, so does not matter how great is the splint technique if periodontal ligament cells became necrotic.
Non-rigid immobilization is the ideal device due to its passive, atraumatic and flexible features, which allows a certain functional movement, and thus a functional arrangement of the periodontal ligament fibers, reducing the risk of external resorption and ankyloses (2, 10, 17, 37, 44, 47-49).
Tensile stimulation of the periodontal ligament fibers
allows bone deposition, and hence, the chances of abutment tooth mobility are lowered [5,8].
The mechanism of action behind these non-pharmacological methods is to loosen the tightly grouped periodontal ligament fibers, restoring the normal blood flow, thus preventing the buildup of metabolites that stimulates pain receptors.
The mechanism of chewing gums is to loosen the tightly packed periodontal ligament fibers, restoring the normal blood flow of periodontium, thus preventing the buildup of pain receptors stimulating metabolites and finally curing the pain.
In management of these injuries, "time is tooth"--or more specifically, survival of the periodontal ligament fibers
for reimplantation decreases with time.
Tissue sections showed that the replanted tooth was surrounded by newly formed, functional periodontal ligament fibers
and new cementum, the essential ingredients of a healthy tooth attachment.
(17) In a chronic inflammatory process such as periodontitis, exaggerated amounts of proinflammatory mediators are released (e.g., TNF-[alpha] and interleukins), causing destruction involving the periodontal ligament fibers
, connective tissue of the gingiva, and ultimately, the supportive alveolar bone.
The roots were scaled with Gracey 7-8 periodontal curettes (Neumar, Sao Paulo, SP, Brazil) in order to remove periodontal ligament fibers
Overall there was significant difference when comparing groups A (normal environment), B (silent group), and C (low frequency noise exposed) regarding arrangement of Periodontal ligament fibers
, thickness of the ligament, thickness of wall of blood vessels and destruction of alveolar bone.
Scanning electron microscopic observations of the periodontal ligament fibers
and cells in rat molar teeth.
