“…This result is in accordance with the finding of Michalakis K et al [3] were dimensional stability of elastomeric materials showed 0.18% dimensional change after 24 hours and significant change in dimensional stability even after 168 hours. The reason might be that polyvinyl siloxane has longer polymerization period resulting in sustained contraction period.…”

“…0.016% and continued to show drastic change over a period of 72 hours 1.017% . The results of this study seem to be in accordance with an experimental study by Michalakis K X, Pissiotis A, Anastasiadou [3] on physical properties of interocclusal recording media. ZOE undergoes continues contraction after 1 hour and continues to show significant dimensional change along with weight loss.…”

“…The ideal requirements of materials to be used for bite registration are[1-3,5-7] 1)It should become rigid and exhibit minimal dimensional change after setting 2) It should have limited resistance before setting to avoid displacement of teeth or mandible during closure 3) It should produce accurate record of incisal and occlusal surface of the teeth 4) It should be easy to manipulate 5) It should not produce adverse effects on the tissues involved in procedure 6) It should allow easy verification.…”

BackgroundThe introduction of different interocclusal recording materials has put clinicians in dilemma that which material should be used in routine clinical practice for precise recording and transferring of accurate existing occlusal records for articulation of patient’s diagnostic or working casts in the fabrication of good satisfactory prosthesis. In the era of developing world of dentistry the different materials are introduced for interocclusal record with different brand names because of this; the utility of the material is confusing for successful delivery of prosthesis with lack of in vitro or in vivo studies which will predict the property of the material with utility recommendations.Purpose of the studyThe aim of this multicenter research is to evaluate the time dependent linear dimensional stability of three types of interocclusal recording materials; which gives very clear idea to clinicians in regard to its usage in routine practice and recommendations for usage of the different materials. Also to find out ideal time for articulation of three types of interocclusal recording materials with accuracy.Materials and methodCommercially available and ADA approved Polyether bite registration paste (Ramitec), Poly vinyl siloxane bite registration paste (Jetbite) and Zinc oxide eugenol (ZOE) bite registration paste (Super bite) were used in the study.A stainless steel die was made according to modified American dental Associations (ADA) specification no. 19. Each one of the tested materials were manipulated according to manufacturers’ instructions. The materials separated from die, 3-mins after their respective setting time, resulted in disks of standard diameter. Two parallel lines and three perpendicular lines reproduced on the surface. The distance between two parallel lines was measured at different time intervals i.e. 1 hour, 24, 48 and 72 hours by using travelling microscope (magnus) and compared with standard die measurements made according to ADA specification no.19 to find out the dimensional stability of these interocclusal recording materials. Total 120 samples were made for observation and results were subjected to statistical analysis. Statistical analysis was performed using analysis of variance (ANOVA) and then Tukey’s Honestly Significant Difference (HSD) test for comparison among groups at the 0.05 level of significance. After statistical analysis of the data, results were obtained and analyzed for interpretation.ResultsThe results shows significant difference between the dimensional stability of all three material at different intervals with p-value <0.05. Comparatively the polyether bite registration material showed less distortion with good dimensional stability compared to Poly vinyl siloxane bite (Jetbite), Zinc oxide eugenol(ZOE) bite (Super bite) at 1 hour, 24, 48, and 72 hours.ConclusionThe dimensional stability decreased with increase in time and is influenced by both material factor and time factor. Polyether was found to be more dimensionally stable interocclusal recording materi...

“…Water of consistency and setting time Cement reacts with water and CaOH is liberated during the Portland cement hydrated. Calcium hydroxide reacts with the colloidal acid hydrates to form hydrated calcium aluminates, silicates and hydrogarnets (15,16) . The reactions of tricalcium aluminates solid-solution phases predominate at the morning hydration.…”

TWO different superplasticizers particularly Cyclohexanone formaldehyde sulfanilate (CFS) and Cyclohexanone glyoxylic sulfanilate (CGS) were prepared; also, their effect on mechanical and physico-chemical properties of oil well cement was assessed. The chemical structures were affirmed by FTIR technique. The designed chemical compounds were predestined as superplasticizers for cement pastes. The pastes made by superplasticizers (CFS or CGS) addition to cement by the ratios of 0, 0.25, 0.50, 0.75, and l.00 as mass % of cement. The consistence water, setting time, chemically combined water content (Wn), the hydration rate and compressive strength of the admixed hardened pastes were predestined at various time periods. The phase composition was intended by DSC and XRD techniques. The results revealed that as the admixture dose rate increases the demand cement paste water of consistency decreases. Also, as the admixture addition rate increases the chemically combined water content decreases, so the rate of hydration decreases; meanwhile compressive strength magnitudes increase in accounts for the low water/cement (initial porosity) of the sample.The factors affecting the cementing process of oil wells are the temperature, pressure, minerals, impurities and the water/cement ratio (1,2) . These factors jointly or individually having a fastening effect on the initial setting time of cement which negatively affects the workability and makes it impossible to pump as a result of the coming down of the cement deep into the ground and this process may take several hours. So begin the use of chemical mixtures (3) , such as superplasticizers, which work to increase fluidity and to facilitate the process of pumping cement slurries to the depths of wells easily with no changing in the cement properties (4) . Strong repulsion happens because the superplasticizer and the cement particle's charge by a similar charge (5) . Given the large molecular weight of superplasticizers, the plasticizers are also working as pore fillers between the particles of cement which reduces the water/cement ratio and therefore gives a high magnitude compressive strength (6)(7)(8)(9) . The synthesis processing parameter of water soluble sulfonated cyclohexanone formaldehyde (SCF) superplasticizer has influence on the inherent viscosity and the dispersing
