Effects of Chemical Disinfections on Dimensional Stability of Irreversible Hydrocolloid Impression
No full textThis study was carried out to determine the linear dimensional stability of irreversible hydrocolloid impression materials on resulting dental stone casts after being immersed in two market available chemical disinfectants. Thirty impression samples for each of the two different alginates were taken from a maxillary acrylic model and then immersed in 1% alkylbenzyldimethylammonium chloride (ADBAC) for 3 minutes and 0.5% NaOCl for 10 minutes respectively. Selected measurements were made on the stone casts retrieved from each impression materials. The measurements were analyzed by using independent t test; for comparison among groups. Level of significance was set at p<0.05. Linear dimensions of all tested alginate impressions had changed after immersion in each chemical disinfectant. But these changes were clinically acceptable even for the least stable in dimension (maximum deviation 0.39 mm). Therefore, 1% alkylbenzyldimethylammonium chloride (ADBAC) should be considered as chemical disinfectant of choice for immersion disinfection of irreversible hydrocolloid impression material like the recommended chemical disinfectant, 0.5% sodium hypochlorite
In vitro study of Coronal Leakage of Four Temporary Filling Materials Immersed in Alcoholic Methylene Blue Dye
No full textAbstract
Introduction: Temporary restorative materials
are placed in access cavity to provide the coronal
seal of the root canal during multi-visits RCT. This
in vitro study was designed to evaluate the coronal
microleakage of four different temporary restorative
materials commonly used in endodontics in
Myanmar, viz., MD.Temp, Orafil, Caviton, Zinc oxide
eugenol.
Materials and Methods : Forty-four extracted human
premolars were selected, and access cavity was
prepared. Pulp chambers were filled with wet cotton
pellets leaving approximately 4 mm coronally. Forty
teeth were randomly divided into four experimental
groups equally. The remaining four teeth were equally
divided into two control groups. Access cavities in
each group were filled with one of the above tested
materials, and immediately put into the water. Tooth
surfaces except occlusal surface were then coated
with nail varnish. Equal parts of 2% methylene blue
and methylated alcohol were mixed to prepare a dye
solution. Samples were immersed in dye for 10 days
at 32 ± 2°C. Teeth were rinsed, dried, and sectioned
mesiodistally and evaluated under a stereomicroscope
at a magnification of 15X for linear dye penetration
along cavity walls. Data were analyzed using KruskalWallis and Tukey HSD tests.
Results : The lowest microleakage value
was observed in MD.Temp and Orafil, and the
highest in Zinc oxide eugenol (ZOE). Caviton was
not statistically different from Orafil and ZOE, but
significantly higher in microleakage than MD.Temp.
Clinical Significance : ZOE which is dissolvable in
alcohol was the least effective material for preventing
microleakage, while MD.Temp and Orafil provided
the best sealing in content of alcohol in this study
Design, Fabrication and Performance Analysis of Loopwing Horizontal Axis Wind Turbine
No full textThis research presents the design, fabrication and performance analysis of loopwing horizontal axis wind turbine. Among the many types of wind turbine, most of them failed in efficiency because of the higher rotating speed required in other conventionalhorizontal axis wind turbine. Another vertical axis wind turbine suffers unbalance torque between the right and left side whichcauses vibration. Loopwing horizontal axis wind turbine is operated at low rotating speed without reducing energy efficiency.There is no vortex discharge and noise because loopwing horizontal axis wind turbine has strip ribbons as its blade tip portionends in a loop shape. Loopwing horizontal axis wind turbine blade is designed by the using of basic design formula such asangular momentum theory, blade element theory. The NASA SC(2)-0402 is chosen as the loopwing horizontal axis wind turbineblade profile by comparing it with a similar airfoil shape from the results of Profili Software. The model of loopwing horizontalaxis wind turbine is drawn by using Solidworks 2018. Performance testing is carried out on the roof of Main-Building atMandalay Technological University. The wind turbine hub is placed 14.6 m above the ground. The material of loop type bladewind turbine is stainless steel. The performance analysis of loopwing horizontal axis wind turbine is emphasized in this research.This loop type blade wind turbine can be started wind speed at 1.5m/s and cut-out wind speed at 12m/s. Electrical power outputcan be produced by about 100 W by the following horizontal axis wind generator at rated wind speed 6m/s. Rotor diameter is1.5m and the no. of the blade is three and the tip speed ratio is
Study on Accuracy of Digital Scanning and Conventional Methods in Partially Edentulous Dental Impression
No full textIntraoral impression making is a basic technique in dental practice that is used to generate an imprint of the oral situation. Inaccurate impression may result in prosthesis misfit, which may lead to mechanical and/or biological complications. The current gold standard is the physical impression made with an elastomeric impression material. Recently, the advent of digital technology is developing expeditiously. Digital impressions have emerged as alternative to conventional impression technique and materials. The purpose of this in vivo study was to compare the accuracy of digital scanning and conventional techniques in partially edentulous dental impressions. Complete-arch impressions were obtained using two conventional (polyvinyl siloxane, PVS; direct scannable condensational silicone, S-CS) and one digital (3Shape Trios, TRI) techniques. The cast measurements were compared with intraoral measurements. No significant differences in trueness and precision were found between digital impression and conventional silicone impressions (p>0.05). Within the limitations of this
in vivo study, digital intraoral impression systems showed similar accuracy comparable to highly accurate conventional impression techniques. These techniques can also provide excellent clinical results within their indications and can be used as alternative to conventional impression techniques
