Many studies suggest that mutans streptococci (MS), Lactobacillus (LB), and salivary buffering capacity are important risk factors for dental caries. However, target populations most were children. In adult patients, the same affect number of fillings or prostheses secondary It is therefore to investigate these as predictors caries in adults. present study, we evaluated oral conditions subjects at private offices using bite-wing radiographs. Detection LB level Dentocult had a statistically...
Titanium and stainless steel wires used for retainers in orthodontic procedures were coated with Ag ions the effects of coating on common oral pathogens their pathogenicity investigated. Two species cariogenic three periodontopathic bacteria assessed. Biofilms Streptococcus sobrinus two VSC gases produced by P. gingivalis also examined. ioncoated showed marked antibacterial activities compared uncoated wires; most cases, differences statistically significant (p<0.05). All ion-coated (Ti+ SS+...
This case report describes the orthodontic treatment performed for open bite caused by internal derangement (ID) and osteoarthritis (OA) of temporomandibular joint (TMJ). A Japanese woman, aged 31 years 11 months, referred to our department an oral surgeon had with clockwise rotation mandible degeneration condyle. The overbite was corrected through intrusion maxillary mandibular molars using mini-screw implants induce counterclockwise mandible. Then, second premolars were extracted...
Orthodontic appliances often cause oral diseases such as dental caries and gingivitis due to the attachment of an biofilm. However, there are few reliable methods remove biofilm from orthodontic appliances. The aim this study was investigate effects microbubbled water on removal biofilms made with Streptococcus mutans or Candida albicans were immersed remaining detected measured using a micro-plate reader absorbance meter. had sufficient effect significantly higher than those tap (S. mutans:...
Background and Objective During orthodontic tooth movement (OTM), periodontal ligament (PDL) is remodeled dynamically, which requires sufficient blood supply for the regeneration of PDL. However, little known about remodeling vessels during OTM. In this study, we hypothesized that tensile strain upregulates matrix metalloproteinase‐12 (MMP‐12) expression in tension zone induces angiogenesis via degradation type IV collagen (Col‐IV) vascular endothelial basement membrane early stage Material...
Photocatalysts have multiple applications in air purifiers, paints, and self-cleaning coatings for medical devices such as catheters, well the elimination of xenobiotics. In this study, a coating UV-responsive photocatalyst, titanium dioxide (TiO2), was applied to an orthodontic resin. The antibacterial activity on oral bacteria hydrophilic properties mechanical TiO2-coated resin were investigated. ultraviolet A (UVA) (352 nm) light used source. Antibacterial examined with or without...
The aim of the present study was to evaluate albumin adsorption stainless steel (SUS), diamond-like carbon (DLC) and fluorinedoped DLC (F-DLC) films using quartz crystal microbalance (QCM) method. Each sensor characterized atomic force microscopy, surface roughness wettability measurements free energy calculations. Adsorbed amounts bovine serum on F-DLC were significantly lower than that SUS (p<0.05). apparent first-order reaction rate, kobs, larger those Moreover, total energies influenced...
The mechanism of active eruption molars was examined in 36 male adolescent Wistar rats. Histological, histochemical [tetracycline (TC) labelling and alkaline phosphatase (ALP) activity], immunohistochemical [transforming growth factor (TGF)-β1, -β2, -β3] investigations were conducted the rat molar areas. Real-time reverse transcription-polymerase chain reaction (RT-PCR) for mRNA TGF-β performed on periodontal ligament (PDL) dissected out by laser capture microdissection. TC lines showed that...
ABSTRACT Objective: To clarify whether the concept of main occluding area, where hard food is initially crushed, exists in patients who have a jaw deformity. Materials and Methods: Nineteen subjects with normal occlusion, 18 mandibular prognathism, 11 prognathism had undergone orthognathic surgery participated this study. The area was identified by clenching Temporary Stopping. coincidence, location distance from first molars to were examined. Results: High coincidence obtained all groups,...
ABSTRACT Little is known about the molecular mechanisms of enthesis formation in mature animals. Here, we report that annexin A5 (Anxa5) plays a critical role regulation bone ridge outgrowth at entheses. We found Anxa5 highly expressed entheses postnatal and adult mice. In Anxa5-deficient (Anxa5–/–) mice, sizes outgrowths tibias femur were increased after age 7 weeks. Bone overgrowth was not observed fibrous where fibrocartilage layer does exist. More ALP-expressing cells Anxa5–/– mice than...
During orthodontic treatment, plaque tends to form around fixed appliances, which increases the risk of dental caries. It has been reported that ultarafine bubble with a diameter <1 μm water (UFBW) effectively removes organic matter. In addition, UFBW is harmless and stable for at least one month refrigeration. The aim this study was examine plaque-removal effect ultrafine establish new method prevent caries in patients during treatment procedures. vitro examined different concentrations...
