effect of mechanical load cycling on microtensile bond strength of self-etch systems to dentin
objective: optimal dentin bonding is not always obtained in clinical practice due to func-tional forces. these forces may provide stresses throughout the tooth and restorative sys-tem, which in turn may affect the adhesive bond. this experimental study evaluated the effect of load cycling on bond strength of self-etch systems. materials and methods: one third of the coronal portions of 48 intac...
متن کاملEffect of resin coat technique on bond strength of indirect restorations after thermal and load cycling.
OBJECTIVE To evaluate the ability of the resin-coat technique used in cavity preparation to protect dentin before impression taking and final cementation and its effect on the tensile bond strength of indirect restorations after thermal and load cycling. METHODS Occlusal enamel was removed from 25 third molars to expose flat dentin. Teeth were divided into 5 groups (n=5): G1, receiving no den...
متن کاملEffect of Three Light Curing Protocols and Load Cycling on Microleakage of Class V Composite Restorations
Objective: Different methods have been suggested to overcome the polymerization shrinkage of composite restorations. Changing the light curing protocol to improve polymerization by using new light curing units is among these methods. The new devices are more efficient, portable and durable and produce less heat. This study aimed to assess the marginal microleakage of class V composite restora...
متن کاملEffect of betaine on cycling sprint power
Methods Sixteen untrained subjects (7 females and 9 males) completed three sprint tests, each consisting of four 12 sec efforts against 5.5% of body weight as resistance; efforts were separated by 2.5 min of cycling at zero resistance. Test one established baseline; test two and three were preceded by daily consumption of 591 ml of a carbohydrate-electrolyte beverage as a placebo or a carbohydr...
متن کاملeffect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
