BACKGROUND With the changing demand in dentistry, a wide range of dental materials is present in the market today. Choosing the best material for a given situation becomes confusing for a clinician. Shear bond strength gives an idea of retentiveness of a material partially. The purpose of the study was to determine and compare shear bond strength (SBS) of packable glass ionomer cement (GIC), resin- modified glass ionomer cement (RMGIC), compomer, and giomer to primary and permanent teeth. METHODS An in-vitro, experimental study was done. 60 freshly extracted permanent first premolars, extracted for orthodontic purpose and 60 freshly extracted over-retained deciduous molars were collected and kept in two groups. Specimens in each group were randomly divided into six subgroups depending on the material to be used. Flat dentinal surface on tooth was prepared over which restorative materials were placed. The prepared specimen was subjected to shear test and the value obtained was compared. Descriptive statistical analysis was performed to calculate the mean shear bond strength of each group. Also, analysis of variance (ANOVA) followed by Tukey’s test was performed with the help of critical difference (CD) at 5 % and 1 % level of significance. The debonded specimen were examined to assess the mode of failure. RESULTS Intragroup comparison for primary teeth showed that composite resin had the highest shear bond strength value (16.21 ± 1.12), followed by Giomer (14.25 ± 1.13), compomer (10.27 ± 1.38), RMGIC (6.06 ± 1.04), packable GIC (3.01 ± 0.85) and conventional GIC (2.94 ± 0.91). In permanent teeth, similar order was seen with composite resin showing highest bond strength (17.82 ± 1.50) followed by Giomer (15.26 ± 1.54), compomer (12.54 ± 1.36), RMGIC (7.00 ± 0.89), packable GIC (3.35 ± 0.98) and conventional GIC (3.30 ± 1.03). Intergroup comparison revealed, the values of shear bond strength (SBS) of all the materials tested was lower in primary teeth. However, the difference was statistically insignificant for conventional GIC and packable GIC. The mode of failure for packable GIC specimens was cohesive within the material, which suggests that the values obtained may not be the strength of the bonded interface but the strength of the material. In RMGIC it was predominantly mixed (cohesive within the material), which indicates that the values obtained were not clearly the strength of the bonded interface but due to inherent weakness of the material. The mode of failure in compomer and Giomer was adhesive failure suggesting that the value obtained was of adhesive bond formed at the interface. CONCLUSIONS Giomer and compomer proved to be the materials with high adhesiveness, so these can be recommended as a suitable restorative material for both primary and permanent teeth. Of the four materials tested, Giomer was found to be the best in terms of SBS in both the primary and permanent teeth. KEY WORDS Compomer, Glomer, Packable GIC, RMGIC, Shear Bond Strength

Abstract Introduction The aim of the current study was to evaluate shear bond strength of resin composite bonded to Theracal LC, Biodentine, and resin-modified glass ionomer cement (RMGIC) using universal adhesive and mode of fracture. Materials and Methods A total of 50 caries-free maxillary and mandibular molars extracted were taken; occlusal cavities were prepared, mounted in acrylic blocks, and divided into five groups based on the liner used. Group 1: Biodentine liner placed into the cavity and bonding agent and resin composite applied after 12 minutes. Group 2: Biodentine liner placed into the cavity and bonding agent and resin composite applied after 14 days. Group 3: RMGIC liner placed into the cavity and bonding agent and resin composite applied immediately. Group 4: RMGIC liner placed into the cavity and bonding agent and resin composite applied after 7 days. Group 5: Theracal LC liner placed into the cavity and bonding agent and resin composite applied immediately. Each sample was bonded to resin composite using universal adhesive. Shear bond strength analysis was performed at a cross-head speed of 0.1 mm/min. Statistical Analysis  Statistical analysis was performed with one-way analysis of variance and posthoc Bonferroni test using SPSS version 22.0. Results and Conclusion Biodentine liner when bonded immediately to resin composite showed minimum shear bond strength. RMGIC when bonded to resin composite after 7 days showed maximum shear bond strength. Mode of fracture was predominantly cohesive in groups having Biodentine and Theracal LC as liner.

SUMMARY Objective To evaluate the shear bond strength (SBS) of three self-adhesive resin cements and a resin-modified glass ionomer cement (RMGIC) to different prosthodontic substrates. Materials and Methods The substrates base metal, noble metal, zirconia, ceramic, and resin composite were used for bonding with different cements (n=12). Specimens were placed in a bonding jig, which was filled with one of four cements (RelyX Unicem, Multilink Automix, Maxcem Elite, and FujiCEM Automix). Both light-polymerizing (LP) and self-polymerizing (SP) setting reactions were tested. Shear bond strength was measured at 15 minutes and 24 hours in a testing device at a test speed of 1 mm/min and expressed in MPa. A Student t-test and a one-way analysis of variance (ANOVA) were used to evaluate differences between setting reactions, between testing times, and among cements irrespective of other factors. Generalized linear regression model and Tukey tests were used for multifactorial analysis. Results Significantly higher mean SBS were demonstrated for LP mode relative to SP mode (p<0.001) and for 24 hours relative to 15 minutes (p<0.001). Multifactorial analysis revealed that all factors (cement, substrate, and setting reaction) and all their interactions had a significant effect on the bond strength (p<0.001). Resin showed significantly higher SBS than other substrates when bonded to RelyX Unicem and Multilink Automix in LP mode (p<0.05). Overall, FujiCEM demonstrated significantly lower SBS than the three self-adhesive resin cements (p<0.05). Conclusions Overall, higher bond strengths were demonstrated for LP relative to SP mode, 24 hours relative to 15 minutes and self-adhesive resin cements compared to the RMGICs. Bond strengths also varied depending on the substrate, indicating that selection of luting cement should be partially dictated by the substrate and the setting reaction.

Abstract Patients undergoing radiotherapy treatment present more susceptibility to dental caries and the use of an orthodontic device increases this risk factor due to biofilm accumulation around the brackets. The objective of this study was to evaluate the shear bond strength to irradiated permanent teeth of orthodontic brackets bonded with conventional glass ionomer cement and resin-modified glass ionomer cement due to the fluoride release capacity of these materials. Ninety prepared human premolars were divided into 6 groups (n=15), according to the bonding material and use or not of radiation: CR: Transbond XT composite resin; RMGIC: Fuji Ortho LC conventional glass ionomer cement; GIC: Ketac Cem Easymix resin-modified glass ionomer cement. The groups were irradiated (I) or non-irradiated (NI) prior to bracket bonding. The specimens were subjected to a fractioned radiation dose of 2 Gy over 5 consecutive days for 6 weeks. After the radiotherapy, the brackets were bonded on the specimens with Transbond XT, Fuji Ortho LC and Ketac Cem Easymix. After 24 h, the specimens were subjected to shear bond strength test. The image of enamel surface (classified by Adhesive Remnant Index - ARI) was also evaluated and its frequency was checked among groups/subgroups. The shear bond strength variable was evaluated with ANOVA and Tukey’s post-hoc test. GIC group showed the lowest adhesion values among the groups (p<0.05). There was no statistically significant difference among non-irradiated and irradiated groups (p>0.05). As for the ARI, the CR-I group showed the highest material retention on enamel surface among the irradiated groups. RMGIC group showed the highest values for shear bond strength and presented ARI acceptable for clinical practices.
