Purpose: The aim of this in vitro study was to evaluate the microtensile bond strength (microTBS) and hybrid layer morphology of different adhesive systems, either followed by treatment with Nd:YAG laser irradiation or not. Previous studies have shown the effects of Nd:YAG laser irradiation on the dentin surface at restoration margins, but there are few reports about the significance of the irradiation on the hybrid layer.
Materials And Methods: The flattened coronal and root dentin samples of 24 bovine teeth were randomly divided into 8 groups, according to the adhesive system used -- Scotchbond Multi Purpose (SBMP) or Clearfil SE Bond (CSEB) -- and were either irradiated with Nd:YAG or not, with different parameters: 0.
Purpose: The purpose of this study was to evaluate microleakage of cavity preparation in primary teeth made with an Er, Cr:YSGG laser (L) or high-speed drill (HD) and conventional (CGIC) and resin-modified glass ionomer cement (RMGIC).
Methods: One hundred primary teeth were divided into 10 groups (N=10): (a) groups 1 and 2 represented cavities prepared by a no. 1012 diamond bur with HD; (b) groups 3 through 10 represented cavities prepared with an Er, Cr:YSGG laser (with a repetition rate of 20 Hz power settings varying for enamel=2.
