“…Suzuki and others 45 stated that pulpal recovery from tooth preparation trauma is possible by preventing bacterial leakage and its byproducts. Although vital teeth are more resistant to bacterial invasion into dentinal tubules than are non-vital teeth (Nagaoka & others), 42 and the outward fluid movement retards the inward diffusion of bacterial toxins (Pashley & others), 41 mechanically-exposed dentin requires provisionalization to reduce sensitivity and bacterial microleakage (Cagidiaco & others).…”

“…Sealing of the dentin tubules also reduces sensitivity (Cagidiaco & others) 5 by preventing hydraulic fluid flow within the dentin tubules, which is associated with post-operative sensitivity (Brännström; Suzuki, Cox & White; Pashley & others). [44][45][46] It has been shown that cements can be forced into dentin tubules before the luting agent sets (Zaimoglu & Aydin) 47 and microorganisms and their by-products can penetrate into the patent dental tubules post-operatively (Lundy & Stanley; Nagaoka & others). 42,48 Therefore, the early sealing of dentin tubules also may prevent occlusion of dental tubules by PLA remnants and prevent eugenol diffusion across dentin, which may later inhibit polymerization of the bonding agents (Bertschinger & others).…”

Clinical RelevanceBased 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 eugenolfree) used. SUMMARYThis study evaluated the effect of two different types of provisional luting agents (RelyX Temp E, eugenol-based; RelyX Temp NE, eugenol-free) on the shear bond strengths between human dentin and two different resin-based luting systems (RelyX ARC-Single Bond and Duo Link-One Step) after cementation with two different techniques (dual bonding and conventional technique). One hundred human molars were trimmed parallel to the original long axis, to expose flat dentin surfaces, and were divided into three groups. After related surface treatments for each specimen, the resin-based luting agent was applied in a silicone cylindrical mold (3.5 x 4 mm), placed on the bonding-agent-treated dentin surfaces and polymerized. In the control group (n=20), the specimens were further divided into two groups (n=10), and two different resin-based luting systems were immediately applied following the manufacturer's protocols: RelyX ARC-Single Bond (Group I C ) and Duo Link-One Step (Group II C). In the provisionalization group (n=40), the specimens were further divided into four subgroups of 10 specimens each (Group I N, I E and Group II N, II E). In Groups I N and II N, eugenolfree (RelyX NE), and in groups I E and II E, eugenol-based (RelyX E) provisional luting Operative Dentistry, 2007, 32-1, 84-93 agents (PLA), were applied on the dentin surface. The dentin surfaces were cleaned with a flourfree pumice, and the resin-based luting systems RelyX ARC (Group I N and E) and Duo Link (Group II N and E) were applied. In the Dual bonding groups (n=40), the specimens were divided into four subgroups of 10 specimens each (Group I ND, ED and Group II ND, ED). The specimens were treated with Single Bond (Groups I ND and ED) or One Step (Groups II ND and ED). After the dentin bonding agent treatment, RelyX Temp NE was applied to Groups I ND and II ND, and RelyX Temp E was applied to Groups I ED and II ED. The dentin surfaces were then cleaned as described in the provisionalization group, and the resin-based luting systems were applied: RelyX ARC-Single Bond (Group I ND and ED) and Duo Link-One Step (Group II ND and ED). After 1,000 thermal cycles between 5°C and 55°C, shear bond testing was conducted at a crosshead speed of 0.5 mm/minutes. One-way ANOVA, followed by a post hoc Tukey test (α α=0.05) was done. The dentin-resin-based luting system interfaces were evaluated under a scanning electron microscope. There was a significant reduction in the mean shear bond strength values of groups subjected to the provisionalization compared to the control and dual bonding technique groups (p<0.05). The composition of provisional luting did not create a significant difference with regard to reducing shear bond strength values (p>0.05). Wi...

Clinical RelevanceThe presence of a provisional restoration containing eugenol for one week or longer does not interfere with the bond strength of self-etching adhesives to dentin. If a eugenol-based provisional restoration remained in place for only 24 hours, a delay of one week re-establishes proper bond strength. halves that were enclosed in resin cylinders. The cavities were prepared over the buccal/lingual faces with diamond burs. Zinc oxide and eugenol (ZOE) provisional material was inserted into cavities and left for 24 hours, 7 days or 14 days. The cavities not restored with ZOE were used as controls. After ZOE removal or over fresh dentin (control), self-etching Adper SE Plus was applied immediately, after a 7-or 14-day delay. The cavity was restored with non-eugenol provisional material during this delay period. Cylinders of resin cement were built-up over the hybridized dentin. A shear load was applied to the cylinders at a crosshead speed of 0.5 mm/minute until failure. The data were statistically analyzed using twoway ANOVA and Tukey's tests (α α=0.05). Results: Using IRM as a provisional restoration for 24 hours followed by its removal and immediate adhesive application resulted in the lowest values of shear bond strength. There was no significant difference between the other experimental conditions. Conclusions: The use of IRM for 24 hours adversely affected the shear bond strength of a self-etching adhesive to dentin. The recovery of the proper bond strength occurred one week after IRM removal.

“…Moreover, IDS method can protect the tooth from the consequences of microleakage by sealing the dentin tubules that are vulnerable to bacteria invasion, immediately after completion of the preparation 16) . Sealing of the dentin tubules also reduces sensitivity by preventing hydraulic fluid flow within the dentin tubules, which is associated with postoperative sensitivity 17) . In this study, 3 step total-etch subgroup in IDS group exhibited the highest bond strength.…”
