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.

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.

The formation of a hybrid layer is the main bonding mechanism of current dentin-bonding systems. This study evaluated the morphology and thickness of the resin-infiltrated dentinal layer after the application of adhesive systems. The dentin-bonding agents were evaluated on flat dentinal preparations confected on the occlusal surfaces of human teeth. The test specimens were prepared and inspected under scanning electron microscopy at a magnification of X 2,000. The adhesive systems were responsible for different hybrid layer thicknesses (p < 0.05), and the mean values were: for Scotchbond MP Plus (SM), 7.41 ± 1.24mum; for Single Bond (SB), 5.55 ± 0.82mum; for Etch & Prime 3.0 (EP), 3.86 ± 1.17mum; and for Clearfil SE Bond (CB), 1.22 ± 0.45mum. The results suggest that the conventional three-step adhesive system (SM) was responsible for the thickest hybrid layer, followed by the one-bottle adhesive (SB). The self-etching adhesives, EP and CB, produced the formation of the thinnest hybrid layers.

Dogs were utilized in a study to compare the bond strengths of dentin bonding agents made to dentin in vivo and then again in vitro in the same teeth 30 min, one day, one week, and one month post-extraction. No statistically significant differences were observed between bonds made in vivo and those made in vitro at any time period. Contamination of the dentin surfaces with blood or saliva lowered the bond strengths, but these could be restored to control values by re-surfacing of the dentin with a bur.

Composite resin is a widely used aesthetic restoration. The restoration can fail due to secondary caries. Chlorhexidinegluconate 2% is used as a cavity disinfectant to eliminate microorganisms on the prepared cavity and to prevent thesecondary caries. The purpose of this study was to analyze the effect of chlorhexidine gluconate 2% to the bondstrength of composite resin with self etch system adhesive on dentine. Sixteen specimens of buccal dentine of premolarscrown are divided into 2 different groups. Group I: Clearfil SE Bond self-etch primer was applied for 20 seconds,Clearfil SE Bond bonding was applied for 5 seconds and polymerized for 10 seconds. Composite resin was constructedincrementally and polymerized for 20 seconds. Group II: prior to self etch primer application as in group I,chlorhexidine gluconate 2% was applied for 15 seconds. Shear bond strength was tested using Testing machine andanalyzed with unpaired T test. The highest shear bond strength was obtained by applying chlorhexidine gluconate 2%.The study concludes that chlorhexidine gluconate 2% application to dentine did not affect significantly to the bondstrength composite resin using self etch adhesive systems.

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.
