ABSTRACTObjectives: First to compare different dentin bonding agents’ shear bond strength to primary and permanent dentin. Secondly to compare the fracture failure modes and making an attempt to develop a statistical model that could be helpful in predicting them.Methods: Extracted human primary and permanent molars were used as substrates (dentin). The shear bond strength of composite to substrate was measured and fracture surfaces were evaluated visually and with stereomicroscope. Using the data obtained, a statistical model was built in order to predict the failure modes.Results: Higher bond strength values were obtained for permanent dentin. Total-etch adhesives displayed higher shear bond strength values than the self-etch adhesive. Adhesive failures were more frequently seen in primary dentin. Self-etch adhesive system displayed more adhesive failures. Prepared model confirmed the negative relationship between shear bond strength and the probability of observing adhesive failure.Conclusions: There should be an application protocol for the usage of dentin bonding agents in primary dentin. Further development of statistical and fuzzy models for failure modes can be supportive alternatives for microscopic evaluations and also be helpful in understanding and eliminating the factors which are responsible for the formation of adhesive failures and for achieving clinically more successful adhesive restorations.

Purpose: The purpose of this study was to evaluate the immediate bond strength of two sixth generation and two seventh generation dentin bonding agents to superficial dentin. Specimens were prepared to exposed superficial dentin and either Clearfil SE, Clearfil S3, Adper Prompt-l-pop of G-bond was applied over the dentin surface and light cured. Then composite resin was applied to the treated surface and light-cured in two increments. Specimens were tested 15 minutes after they were made for shear bond strength at 0.01 cm/min. Clearfil SE had statistically higher bond strength than the other three adhesives evaluated (42.9 MPa). There was no statistical difference among Clearfil S3, Adper Prompt-l-pop and G-Bond. The dentin adhesive with an application of an acidic primer before the application of the adhesive showed better immediate bond strength.

Clinical Relevance Based on in vitro results in extracted teeth, the dual bonding method used was effective in restoring the shear bond strength values that decreased after applying provisional luting agent regardless of the composition of the provisional luting agent (eugenol-based or eugenol-free) used.

ABSTRACT Aim To evaluate the influence of salivary contamination during dentin bonding procedures on shear bond strength and to investigate the effect of contaminant-removing treatments on the recovery of bond strength for two dentin-bonding agents. Materials and methods Seventy-seven human maxillary and mandibular molars were randomly divided into two groups for total-etch adhesive (Single bond-3M ESPE, USA) and self-etch primer (UniFil Bond-GC, Tokyo, Japan) and subjected to contamination with saliva. The data for each group were subjected to one-way analysis of variance (ANOVA) followed by the Student Newman-Keuls test to make comparisons among the groups (p < 0.05). Results Salivary contamination had less adverse effect on the shear bond strength of single bond total-etch adhesive when it was blot dried or washed. UniFil bond was tolerant of salivary contamination, except when contamination occurred after application of the primer. Conclusion In single bond adhesive, when the etched surface is contaminated by saliva, blotting the surface and applying the primer can recover the bond strength. Complete drying of the salivary contaminated surface should be avoided. In the UniFil bond groups, the repriming treatment (UF-V and UF-VI) resulted in the recovery of shear bond strength in the specimens contaminated after priming. Clinical significance The results of this study showed that total- etch adhesive (single bond) was not affected by salivary contamination on the etched surface when the bonding surface was kept moist. Self-etch adhesive (UniFil bond) also tolerated salivary contamination except when the contamination occurred after application of the primer.

Objectives. To examine the effect of immediate dentin sealing (IDS), with dentin bonding agents (DBAs) applied to freshly cut dentin, on the shear bond strength of etched pressed ceramic luted to dentin with RelyX Unicem (RXU) cement.Method. Eighty extracted noncarious third molars were ground flat to expose the occlusal dentin surfaces. The teeth were randomly allocated to five groups (A to E) of sixteen teeth each. Groups A to D were allocated a dentin bonding agent (Optibond FL, One Coat Bond, Single Bond, or Go!) that was applied to the dentin surface to mimic the clinical procedure of IDS. These specimen groups then had etched glass ceramic discs (Authentic) luted to the sealed dentin surface using RXU. Group E (control) had etched glass ceramic discs luted to the dentin surface (without a dentin bonding agent) using RXU following the manufacturer’s instructions. All specimens were stored for one week in distilled water at room temperature and then shear stressed at a constant cross-head speed of 1 mm per minute until failure. Statistical analysis was performed by ANOVA followed by post hoc Tukey HSD method () applied for multiple paired comparisons.Results. The shear bond strength results for group A to E ranged from to  MPa. One-way ANOVA demonstrated a difference () between the groups tested and the Tukey HSD demonstrated a significant () difference between the shear bond strength (SBS) of Optibond FL (Group A) and Go! (Group D). There was no statistical difference () in the SBS between the test groups (A–D) or the control (group E).Conclusion. IDS using the dentin bonding agents tested does not statistically () affect the shear bond strength of etched pressed ceramic luted to dentin with RXU when compared to the control.

ABSTRACT Most modern adhesive systems are superior to their predecessors, especially in terms of retention that is no longer the main cause of premature clinical failure. Recent adhesives also appear less sensitive to substrate and other clinical covariables. Various recent trials have been conducted on various issues like the antibacterial properties of self-ethching dental adhesive system (which are effective against bacteria that invade through microleakage at the resin dentin interphase), shear bond strength of composite resin to dentin, using newer dentin bonding agents, nanoleakege expression in bonded dentin and next generation bonding agents. This paper gives the insight to the various recent trials on dental adhesive systems. How to cite this article Kakar S, Goswami M, Nagar R. Dentin Bonding Agents-II Recent Trials.
