摘要

Aim: To evaluate Shear bond strength (SBS) of resin modified glass ionomer cement (RMGIC) on caries affected dentin after using different cavity disinfectants i.e., chlorhexidine gluconate (CHX), Er,Cr:YSGG laser (ECYL) and photodynamic therapy (PDT).Material and methods: Total 50 freshly extracted mandibular molars were obtained through non-traumatic extraction. All the samples were rooted vertically within self-cure acrylic resin blocks up to cervical level so that only corona' portion remain visible. Silicon carbide grinding discs 1200 and 600 grits was used to prepare the teeth. However affected dentin remains untouched. All samples were randomly distributed in to five groups (n = 10). Group 1: 2 % CHX, Group 2: 2 % solution of methylene blue (MB) and Diode laser, Group 3: Indocyanine green (ICGP) solution and Diode laser, Group 4: curcumin (CP) and LED curing unit, Group 5: ECYL. The specimens were then stored at a temperature of 37 degrees C for 24 h and 100 % humidity before specimens were placed in to universal testing machine for the SBS measurements. Failure mode examination was performed by a stereomicroscope. ANOVA test analyze inter group comparison. Tukey HSD test was used to analyze multiple group comparison. The level of significance was set at p 0.05 value.Results: Among all the groups, group 1 (control, CHX treated) demonstrated highest SBS value (18.31 +/- 1.06 MPa). Whereas lowest SBS was displayed by group 2 (PDT, MB) (12.31 +/- 0.57 MPa). Dentin disinfected with group 4 (PDT, CP) (16.86 +/- 0.97 MPa) and group 5 (ECYL) (17.39 +/- 2.26) showed comparable result to that of CHX (p 0.05).Conclusions: Bond strength of RMGIC bonded to CHX disinfected caries affected dentin was highest among study groups. Use of MB showed lowest shear bond strength outcomes. Moreover, application of ECYL and curcumin with LED showed bond strengths comparable to CHX control.
