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.
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
Scanning electron microscopic observations of the periodontal ligament fibers
and cells in rat molar teeth.
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.
The slides were studied for general ar- chitecture of the periodontal ligament fibers (regular or distorted) and erosion of alveolar bone with detached pieces of bone among the fibers.
The junction of periodontal ligament fibers with the bone in most of specimens was irregular with distort- ed arrangement of fibers at the ends.
The junction of periodontal ligament fibers with the bone in almost all of specimens was regular with well-organized arrangement of fibers at the edges.
