The aim of this study was to determine the effects of an acrylic-based resilient liner (ARL) on masticatory ability by verifying the null hypothesis that masticatory performance and mandibular movements do not differ between people who wear mandibular complete dentures with ARL and those who wear complete dentures with conventional acrylic resin (CAR). From April 2004 to July 2006, we conducted a randomized controlled trial study at two centres. After written informed consent was obtained from 74 edentulous patients, they were randomly allocated to either the ARL group or CAR group. Masticatory performance and mandibular movement at the lower incisal point during chewing were measured as the outcomes. We did not observe significant differences in both outcomes between the groups. The chewing cycles were significantly different during the initial, middle, and final phases of mastication. Within the limitations of the current study, the results indicate that the acrylic-based resilient denture liners used have no clinical impact on the masticatory ability of complete denture wearers.
Sugammadex 4 mg/kg was required to reverse a moderate rocuronium-induced neuromuscular block when the corrugator supercilii muscle is used for monitoring.
The efficacy of ADMPC transplantation for periodontal regeneration was evaluated using a beagle dog model. The furcation bone defects were surgically created and autologous transplantation of ADMPCs with fibrin gel was performed. Six weeks after transplantation, periodontal regeneration was analyzed using micro-CT, which showed a significant increase in bone formation at sites where ADMPCs were applied compared with control sites. Histological analysis revealed new cementum formation on the instrumented root surface was significantly increased following ADMPC transplantation and connective tissue fibers were inserted vertically in newly formed bone and cementum. Importantly, no instances of undesirable healing, such as root resorption or ankylosis, were observed at any sites examined. These results indicate that transplantation of ADMPCs with fibrin gel promotes periodontal tissue regeneration. Rec
Low frequency f = 1 5 − 1 3 f ci , (f ci : ion gyro frequency in the external field B w ) waves are excited with an antenna which is compatible with a reactor in a plasma with field reversed configuration (FRC). Near and outside the separatrix r s of the FRC plasma, though the applied wave is mainly in compressional mode, azimuthal and radial components are observed in the magnetic field disturbance of the excited wave, which propagate with the dispersion relation consistent with the shear Alfvén wave. These disturbances penetrate deep into the FRC plasma across the surface where the wave frequency exceeds local ion gyro frequency and propagate along magnetic lines of force with sound velocity, which behaviour is consistent with the shear Alfvén wave with finite temperature correction. Axial magnetic disturbance propagates axially and radially from the antenna across the plasma column.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
