Ceramic specimens (n=15) were bonded to dentine surfaces with a resin luting cement (Variolink II) in either LP or DP mode and polymerised according to one of four polymerisation profiles as follows: control group: 600 mW cm(-2) conventional halogen light, 40 s; light emitting diode polymerisation unit group: 1500 mW cm(-2) light emitting diode, 10 s; plasma arc curing (PAC) polymerisation unit 10 s group: 1370 mW cm(-2) PAC, 10 s; and PAC 3 s group: 1370 mW cm(-2) PAC, 3 s. Bond strength (MPa) data were analysed using two-way analysis of variance and Duncan's test (alpha=0.05). Polymerisation mode (p<0.01), type of light unit (p<0.01) and the interactions between the two were statistically significant (p<0.05). No significant differences were found between LP and DP modes except for the PAC 3 s group, in which the LP mode resulted in significantly lower shear bond strength values (10.43 +/- 1.02 MPa) compared with the DP mode (12.88 +/- 1.73 MPa).eninfo:eu-repo/semantics/closedAccessResin luting cementPolymerisationShear bond strengthLeucite reinforced full ceramicArticle152919510.1179/143307511X129982229186602-s2.0-79957452325Q2WOS:000290848000004Q4
