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...

OBJECTIVES This study examined the effects of additional acid etching on the dentin bond strength of one-step self-etch adhesives with different compositions and pH. The effect of ethanol wetting on etched dentin bond strength of self-etch adhesives was also evaluated. MATERIALS AND METHODS Forty-two human permanent molars were classified into 21 groups according to the adhesive types (Clearf...

 Gereç ve Yöntemler: Yetmiş iki adet çekilmiş çürüksüz insan üçüncü büyük azı dişi rastgele 18 gruba ayrıldı (n=4). Dentin yüzeyleri #600-grit silikon-karbit kağıt ile cilalandı. Kontrol grubunu Clearfil SE Bond [SE] ...

BACKGROUND Bleaching the discoloured teeth may affect the tooth/composite interface. The aim of this in vitro experimental study was to evaluate the effect of vital tooth bleaching on microleakage of existent class V composite resin restorations bonded with three dental bonding agents. METHODS Class V cavities were prepared on buccal surfaces of 72 intact, extracted human anterior teeth with ...

Objective: The current study aimed to evaluate the effect of diode laser irradiation (980 nm) and warm air drying(50°C) on shear bond strength between Lithium di-silicate (IPS e.max; Ivoclar) human dentin using both(Etch & Rinse) adhesive, Adper™ Single Bond 2 (3M ESPE) (Self-etch) UniversalTM(3M before adhesive polymerization. Material Methods: 54 sound lower molars were sectioned toobtain...

The research is set to examine Academic Staff Union of Universities (ASUU) strikes and academic performance of students in Ekiti State University (EKSU) Ado-Ekiti. The research employed multistage sampling technique to select the faculties and the departments from where six hundred and four (604) respondents were selected, questionnaires and interviews were employed to draw information from res...

The principal paradigm for gamma-ray bursts (GRBs) suggests that the prompt transient gamma-ray signal arises from multiple shocks internal to the relativistic expansion. This paper explores how GRB prompt emission spectra can constrain electron (or ion) acceleration properties at the relativistic shocks that pertain to GRB models. The array of possible high-energy power-law indices in accelera...
