“…Adhesive strength after this so called immediate dentin sealing (IDS) was compared with the conventional adhesive cementation, delayed dentin sealing (DDS), which is a common procedure for cementation of fixed dental prosthesis. In these studies, bond strength results employing DDS varied between 2 to 12 MPa, whereas application of IDS resulted in significantly higher mean bond strength results between 15 and 58 MPa depending on the test method [12,[14][15][16]. Apparently, application of the adhesive resin on freshly cut dentin and further polymerization of the adhesive resin over time improved adhesion of bonded restorative materials [17,18].…”

OBJECTIVES Adhesion on dentin is less reliable than on enamel, which could affect the durability of laminate veneers (LV). Immediate dentin sealing (IDS) is suggested instead of delayed dentin sealing (DDS) to overcome hypersensitivity and prevent debonding from dentin. This study evaluated the effect of IDS and DDS on the durability of Li2Si2O5 laminate veneers in vitro. METHODS Window preparations were made on the labial surfaces of sound maxillary central incisors (N=50). They were randomly divided into five groups: Group 1: Enamel only+H3PO4+Adhesive (control); Group 2: <1/4 dentin+H3PO4+DDS (2 weeks later); Group 3: Complete dentin+H3PO4+DDS (2 weeks later); Group 4: <1/4 dentin+H3PO4+IDS; Group 5: Complete dentin+H3PO4+IDS. Li2Si2O5 laminate veneers (e.max Press) were bonded to the labial surfaces of the teeth with adhesive resin cement (Variolink Veneer). IDS layers were silicacoated (CoJet System) and silanized (ESPE-Sil). The teeth with their bonded laminates were thermocycled (10.000× cycles) and then subjected to static loading (1mm/min). Failure type and location after debonding were classified. Data were analyzed using ANOVA and Tukey's post hoc test ( =0.05). Two-parameter Weibull distribution values including the Weibull modulus, scale (m) and shape (0), values were calculated. RESULTS Mean fracture strength (N) per group in descending order was as follows: Group 5 (576±254), Group 4 (478±216), Group 1 (473±159), Group 2 (465±186), and Group 3 (314±137). The presence of complete dentin exposure sealed with DDS after 2 weeks on the bonded surface (Group 3) resulted in significantly lower fracture strength results than those in group 5 with IDS (p=0.034). Weibull distribution presented higher shape (0) for Group 1 (3.67), than those of other groups (2.51-2.89). Failure types were predominantly adhesive failure between the cement and the laminate veneer in Groups 1, 2, 4 whereas Group 3 presented more often complete adhesive failures between the cement and dentin. In Group 5, failures showed some IDS and cement with or without ceramic fracture attached on the tooth. SIGNIFICANCE When laminate veneers are bonded to a large dentin substrate, application of immediate dentin sealing improves adhesion and thereby, the fracture strength of Li2Si2O5 laminate veneers.

This study assessed the bond strength of a resin cement when Immediate Sealed Dentin (ISD) was contaminated by different temporary cements applying a microshear test. Forty-eight fragments of third molar crowns were mounted in acrylic resin and worn until the dentin was exposed. The substrates were sealed with a 3-step conventional adhesive system and divided into four groups (n=12): Control (without temporary cement) and three groups that used different temporary cements -Provy, RelyX Temp NE, and Provitemp. The temporary cements were removed after 7 days of storage. Resin cement RelyX ARC was applied to the contaminated substrates. Microshear bond strength was evaluated using a universal testing machine (0.5 mm/min). Data was analyzed with ANOVA and a Dunnett post-hoc test (p<0.05). Additionally, three samples from each group were prepared for scanning electron microscope analysis. Means and standard deviations of microshear bond strength (MPa) were 17.96±1.65, 16.70±1.43, 20.43±1.30 and 33.75±4.72 for Control, Provy, RelyX Temp, and Provitemp, respectively. Statistically significant difference was observed between the Control and Provitemp samples (p=0.0002). Adhesive failures were dominant (50%), followed by cohesive failures with cement (26%), and cohesive failures with dentin (24%). Residues of Provy and Provitemp were observed on the sealed dentin. Provitemp temporary cement sealing increased the microshear bond strength of the resin cement on dentin treated with IDS.

“…Immediate dentin sealing (IDS) or dual bonding technique has been suggested as an alternative to delayed dentin sealing in order to overcome hypersensitivity and avoid contamination of dentin from impression material and provisional cement [14][15][16][17] and at the same time reduce marginal leakage [18][19][20][21][22][23][24][25].…”

Originally published at: Özcan, Mutlu; Lamperti, Sofia (2015). Effect of mechanical and air-particle cleansing protocols of provisional cement on immediate dentin sealing layer and subsequent adhesion of resin composite cement. Journal of Adhesion Science and Technology, 29(24) Zürich, 2 Abstract: Immediate dentin sealing (IDS) could avoid contamination of dentin from impression material and provisional cement but prior to final cementation of indirect restorations, removal of the provisional cement may damage the IDS. The objectives of this study were to investigate the effect of mechanical and air-particle cleansing protocols of provisional cement on IDS layer and subsequent adhesion of resin composite cement. The cuspal dentin surfaces of human third molars (N=18, n quadrant =72) were exposed by a low speed diamond saw under water cooling and conditioned with an adhesive system based on 3-step etch and rinse technique (OptiBond FL). Provisional cement (Freegenol) was applied on each specimen.They were then randomly divided into 6 subgroups where the provisional cement was removed either by 1)Air-borne particle abrasion with 50 µm Al 2 O 3 particles at 2 bar (AL2), 2) Air-borne particle abrasion with 50µm Al 2 O 3 particles at 3.5 bar (AL3.5), 3) Air-borne particle abrasion with 30 µm SiO 2 particles at 2 bar (SL2), 4) Air-borne particle abrasion with 30 µm SiO 2 particles at 3.5 bar (SL3.5), 5) Prophylaxy paste (Cleanic) (PP) or 6) Pumice-water slurry (PW) at 1500 rpm for 15 s. The dentin surface on each tooth was assigned to 4 quadrants and each quadrant received the cleansing methods in a clockwise sequence. The non-contaminated and non-cleansed teeth acted as the control (N=3, n quadrant =12) (C). Two separate teeth, contaminated and cleansed according to 6 cleansing protocols, were allocated for Scanning Electron Microscopy (SEM) analysis (x2000). The dentin surfaces in each quadrant received resin composite luting cement (Variolink II, Ivoclar Vivadent) incrementally in a polyethylene mould (diameter: 1 mm 2 ; height: 4 mm) and photo-polymerized. The specimens were stored in distilled water for 24 hours at 37ºC until the testing procedures and then shear force was applied to the adhesive interface until failure occurred in a Universal Testing Machine (0.5 mm/min). Microshear bond (µSBS) was calculated by dividing the maximum load (N) by the bonding surface area of the resin cement. Failure types were analyzed using optical microscope and SEM. Data (MPa) were analyzed using one-way ANOVA (α=0.05). Two-parameterWeibull distribution values including the Weibull modulus, scale (m) and shape ( 0 ), values were calculated.Mean µSBS results (MPa) showed significant difference between the experimental groups (P=0.011) and were in descending order as follows: C (8±2. dentin and the adhesive resin, which is a combination of adhesive and cohesive failure in the adhesive resin. Cohesive failure in the dentin was not observed in any of the groups. Weibull distribution presented lower shape ( 0 ) for C (3.9), AL2 (3...
