OBJECTIVES To compare the microleakage among experimental adhesives containing nanoclay fillers after the storages of 24 hours and 6 months. MATERIALS AND METHODS Class V cavities were prepared on extracted human molars with the occlusal margins located in enamel and the cervical margins in cementum. Phosphoric acid was applied to the enamel and dentin margins.Subsequently, the cavities were ...

This study examined the effects of aural and written prompts under two planning conditions (i.e. pre-task planning and no planning) on complexity, accuracy, and fluency of test takers' writing production. Forty learners in an English institute, who had already been classified as intermediate according to the Oxford Placement Test, were assigned to two planning conditions (i.e. no planning and p...

background: the aim of this study was to compare the shear bond strength of four one-step self-etch adhesives with different ph values to enamel and dentin. materials and methods: in this in vitro study, 200 bovine permanent mandibular incisors were used. four one-step self-etch adhesives with different ph values were tested both on enamel and on dentin: adper™ easy bond self-etch adhesive (ph ...

OBJECTIVE To assess the introduction of Practical Obstetric Multi-professional Training (PROMPT) into maternity units and evaluate effects on organisational culture and perinatal outcomes. DESIGN A retrospective cohort study. SETTING Maternity units in eight public hospitals in metropolitan and regional Victoria, Australia. POPULATION Staff in eight maternity units and a total of 43,408 b...

The detection in 10 bursts of an optical counterpart emission (i.e. during the prompt GRB phase) that is 10−104 brighter than the extrapolation of the burst spectrum to optical frequencies suggests a synchrotron self-Compton origin for the GRB emission, synchrotron producing the optical counterpart emission. In this model, the second upscattering of the burst photons yields a prompt GeV–TeV emi...

OBJECTIVE This in vitro study evaluated the effect of Ankaferd Blood Stopper (ABS) contamination on the microleakage of one-step and two-step self-etching adhesives. STUDY DESIGN Class V cavities were prepared at the cemento-enamel junction on both buccal and lingual surfaces of 60 freshly extracted human molars. Teeth were randomly assigned into three groups according to contamination materi...

background and aims. nano-ionomer (ni) interacts with tooth structures superficially, and there is a concern about the enamel bonding ability of mild self-etch ketac primer. this study compared the effect of different adhesive procedures (self-etching and etch-and-rinse approach) on long-term marginal microleakage of nano-filled resin-modified glass-ionomer (ni) cervical restorations. materials...

Self-reference refers to clinician revelations about themselves. Theory and research on self-reference are limited by a lack of uniform conceptualizations. This paper discusses two types of self-reference, self-disclosure, and self-involving responses. Included are definitions of each type of self-reference; description of definitional inconsistencies in the literature; discussion of prevalence...
