Aim: The potential buffering role of probiotic yogurt has not been investigated. The aim of the study was to determine the pH, titratable acidity of a selection of various probiotic yogurts, their buffering effects with an emphasis on the pH range in which the buffer is efficient. Material & Methods: A quantity of 25 ml of each yogurt was titrated with 1 mol/L sodium hydroxide, added gradually by 0.5 ml, until the pH reached 10 to assess the total titratable acidity - a measure of probiotic yogurt's own buffering capacity. Results: The initial pH was the lowest for Activia peach yogurt (4.40± 0.14) and the highest for Danone natural . . . yogurt (5.29± 0.10). The buffering capacities can be listed as follows: Danone natural >Danone peach >Activia plain >Activia strawberry >Activia peach. There were no statistically significant differences observed between yogurts within any of the five groups compared as a whole with one another. (p >0.05). Conclusions: Buffering capacities of probiotic yogurts should be undermined Daha fazlası Daha az

Aim: The purpose of the present study is to evaluate the micro-tensile bond strength to dentin of two all-in-one adhesives and an etch-and-rinse adhesive. Material and Methods: The teeth were randomly divided into three groups for treatment with one of the following adhesives: Adhese One®, Futurabond M® and Adper Singlebond® (control). Roots and the apical floor of pulp chambers were removed with a microtome. The build-ups were vertically sectioned into rectangular (ff1mmx 1mm) compound bars with microtome. The bars were submitted to tensile tests at constant crosshead speed (1mm/min) using a universal testing machine and tested for . . . each adhesive. Fifteen specimens were manufactured and tested for each material for permanent dentin. Fractured surfaces were inspected to determine the mode of fracture. Results: The bond strengths of Adhese One (5,83±3,13 MPa) was significantly lower than Futurabond M (15,76±4,2 MPa) (p:0,0001) and Adper Singlebond (21,14±5,04 MPa) (p:0,0001) while dentin bond strenght of Futurabond M was significantly lower than that of Adper Singlebond (p:0,003). Conclusions: The tested all-in-one adhesives showed lower dentin bond strengths than an etch-and-rinse adhesive Daha fazlası Daha az

Objective of this in vitro study was to evaluate the micro-tensile enamel bond strength of fissure sealants treated by an antibacterial self-etching agent, antibacterial pretreatment prior to application of a self-etching adhesive system and self-etching adhesive system alone using the simplified enamel fissure model. Materials and Methods: Fresh extracted bovine mandibular incisors were randomly divided into four groups: A. 35% phosphoric acid + Clinpro sealant®; B. 35% phosphoric acid + Clearfil protect bond + Clinpro sealant®; C. 35% phosphoric acid + Consepsis Scrub® + Clearfil SE bond® + Clinpro sealant®; D. 35% phosphoric acid . . . + Clearfil SE bond® + Clinpro sealant®. Two pieces (4 ×6 mm) of enamel were secured with wax on a sterile glass slide to a mean distance of 0.6 ± 0.1 mm. Vertically sectioned bars (ff1mmx 1mm) were submitted to tensile tests at constant crosshead speed (1mm/min) using a universal testing machine. Fractured surfaces were inspected to determine the mode of fracture. Regarding statistical analysis, One-way variance, Tukey and Chi-square tests were applied. Results: The micro-tensile bond strengths of group C (34.63±15.59 MPa) was significantly higher than group A (19.86±7.08 MPa) (p:0.0001), group B (24.49±9.38 MPa) (p:0.002) and group D (19.84±9.92 MPa) (p:0.0001). Failures were predominantly adhesive in nature; where there were no statistically significant differences in fracture patterns between groups. (p:0,343). Conclusion: The micro-tensile bond strength of a self-etching adhesive system previously treated with chlorhexidine cavity disinfectant was significantly higher than an antibacterial self-etching adhesive system alone, a self-etching adhesive system and a conventional acid etching system Daha fazlası Daha az
