This True Experimental study compared academic performance of students in class VIII in initial tryout in one of the English Medium Schools of Vadodara, India among three methods of teaching arithmetic subject viz. (i) Conventional Method (in control group –C), (ii) Computer Assisted Instruction (CAI) only (in Experimental Group A Exp A) and (iii) Computer Assisted Instruction with simultaneous...

The aim of this study was to evaluate the surface roughness of restorative composite resins after polishing with aluminum oxide discs and applying an adhesive layer The following composite resins were used: Filtek Z250 (hybrid, 3MESPE, A2) and Filtek Supreme XT (nanofilled, 3M ESPE, A2E). Thirty specimens of each composite were made using a condensation silicone mold (5.0 x 2.0 mm) into which t...

BACKGROUND AND OBJECTIVES The purpose of this study was to evaluate and compare in vitro the fuoride release and uptake from 5 different esthetic restorative materials. MATERIALS AND METHODS Materials tested were conventional GIC - Fuji 7, GC (group1), resin modifed GIC - Vitremer, 3M ESPE (group 2), polyacid modifed composite - Dyract, Dentsply (group 3), fuoride releasing composite - Tetric...

PURPOSE This study evaluated the influence of abutment materials on the stability of the implant-abutment joint in internal conical connection type implant systems. MATERIALS AND METHODS Internal conical connection type implants, cement-retained abutments, and tungsten carbide-coated abutment screws were used. The abutments were fabricated with commercially pure grade 3 titanium (group T3), c...

PURPOSE This study investigated the influence of surface conditioning procedures and repeated firings on monoclinic content and strength of zirconia before cementation. MATERIALS AND METHODS Sintered bar-shaped zirconia specimens were subjected to no surface treatment (control), air abrasion, or grinding (n=21). Their roughness was evaluated using a profilometer, and microscope analysis was p...

Estimations of prompt photon production at FAIR (Facility for Antiproton and Ion Research) energies using the extrapolation of existing data are presented. About 10 −4 prompt γ with p t >2 GeV/c per Au+Au central event at 25 AGeV are expected. With the planed beam intensity 10 9 /s, 1% interaction rate and 10% centrality, at CBM (Compressed Baryonic Matter) experiment one can expect prompt γ ra...

Radiopacity is an important property of composite materials for clinical diagnosis. For seven direct composites (Aelite LS Posterior, Aelite All-Purpose Body, Quadrant Universal LC, Clearfil Majesty Posterior, Clearfil Majesty Esthetic, Filtek Ultimate Dentin, IPS Empress Direct Dentin) and six indirect composites (Ceromega, Epricord, Estenia C&B, Tescera, Signum Ceramis, Solidex), diskshaped s...

The aim of this paper is to examine the role of physical education (PE) teacher and classmate support in relation to sex and BMI status in adolescents' physical activity (PA) in Kosovo. A Classmate and Teacher Support Scale (with additional questions) was used on a cross-sectional sample of 608 girls and 620 boys aged 15-18, randomly selected from secondary schools of seven major municipalities...

Introduction: Enamel demineralization is associated with decrease in saliva pH due to fermentation of sugar by oral commensal. Thus, exploring the changing pattern of saliva pH is meaningful in dental caries prevention. The aim of this study was to compare the changing pattern of saliva pH after consuming different types of sweeteners (sucrose and maltitol). Methods: It was a case-control study...

BACKGROUND Responsiveness to changing photoperiods from summer to winter seasons is an important but variable physiological trait in most temperate-zone mammals. Variation may be due to disorders of melatonin secretion or excretion, or to differences in physiological responses to similar patterns of melatonin secretion and excretion. One potential cause of nonphotoresponsiveness is a failure to...
