Ruffini nerve endings (mechanoreceptors) in the periodontal ligament (PDL) of mouse incisors were examined to elucidate whether experimentally-induced crossbites cause any changes or abnormalities in their morphology and distribution. Anterior guiding planes were attached to the mandibular incisors
OBJECTIVE
To investigate the changes in insulin-like growth factor-1 (IGF-1) expression levels in the degenerative mandibular condylar cartilage.
METHODS
Thirty-six rats were divided into the unilateral anterior crossbite and control groups. The expression levels of IGF-1; IGF-1 receptor (IGF-1R);
Thalassemia poses clear systemic and oral health problems. Clinicians must be aware of various dental treatment needs in these patients. This study was undertaken to assess body mass index (BMI), dental age, salivary alkaline phosphatase levels, malocclusion, and treatment needs in The temporomandibular joint (TMJ) disc plays a role in joint movement and in load absorbance and distribution. An experimental unilateral anterior crossbite (UAC) prosthesis induces mandibular condylar cartilage degeneration in rats. However, the changes in the articular disc are still Maxillary molar distalization is an increasingly popular option for the resolution of Class II malocclusions. This study describes the effects of one particular molar distalizing appliance, the Friction Free Distalize Appliance (2FDA), in a sample of 20 consecutively treated and growing patients to
Purpose. This study is aimed to compare the effects of two different orthodontic forces on crevicular alkaline phosphatase activity, rate of tooth movement, and root resorption. Materials and Methods. Twelve female subjects of class II division 1 malocclusion participated. Maxillary canines with
Craniosynostosis is the premature fusion of cranial bones. The goal of this study was to determine if delivery of recombinant tissue nonspecific alkaline phosphatase (TNAP) could prevent or diminish the severity of craniosynostosis in a C57BL/6 FGFR2C342Y/+ model of neonatal onset craniosynostosis
OBJECTIVE
To investigate the changes in condylar cartilage and subchondral bone of the temporomandibular joint (TMJ) in a mouse model of incisor malocclusion.
METHODS
By bonding a single (single group) or a pair (pair group) of metal tube(s) to the left incisor(s), a crossbite-like relationship was
OBJECTIVE
To investigate whether mechanical stress induces mineral deposits that contribute to matrix degradation at the onset of osteoarthritis (OA) in temporomandibular joint (TMJ) cartilage.
METHODS
Female Spraguee-Dawley rats were subjected to an unilateral anterior crossbite (UAC) procedure.
OBJECTIVE
Dietary loading has been reported to have an effect on temporomandibular joint (TMJ) remodeling via periodontal-muscular reflex. We therefore examined whether reducing dietary loading decreased TMJ degradation induced by the unilateral anterior crossbite prosthesis as we recently
Runt-related transcription factor 2 (Runx2) is an essential transcription factor for osteoblast differentiation, and is activated by mechanical stress to promote osteoblast function. Cleidocranial dysplasia (CCD) is caused by mutations of RUNX2, and CCD patients exhibit malocclusion and often
Increased subchondral trabecular bone turnover due to imbalanced bone-resorbing and bone-forming activities is a hallmark of osteoarthritis (OA). Wnt5a/Ror2 signaling, which can derive from bone marrow stromal cells (BMSCs), takes a role in modulating osteoblast and osteoclast formation. We showed
In order to elucidate the genetic effects on the growth and development of craniofacial regions, HIV-1 transgenic mice (TG mice) which exhibited the phenotype of anterior crossbites were investigated by various methods. Northern hybridization showed that the introduced gene was expressed from 14.5
A 35-year-old white female is presented for case review. According to H. M. Worth, the classification polyostotic fibrous dysplasia, leontiasis ossea type, would be appropriate. Bone lesions are present in the skull, all facial bones, ribs, pelvic girdle and extremities. The patient's
β2-adrenergic signal transduction in mesenchymal stem cells (MSCs) induces subchondral bone loss in osteoarthritis (OA) of temporomandibular joints (TMJs). However, whether conditional deletion of β2-adrenergic receptor (Adrb2) in nestin+ MSCs can alleviate TMJ-OA development remains
