“…In addition, a provisional cement containing eugenol disturbs the bonding of the resin cement because eugenol reduces the free radicals and restrains polymerization of the resin 23,24. Kanakuri et al25 asserted that one cause of the problems associated with ill-fitting restorations would be remaining provisional cement on the abutment surface. Therefore, the complete removal of provisional cement before the definitive cementation of the restorations is recommended.…”

PURPOSEThis study evaluated the effectiveness of various methods for removing provisional cement from implant abutments, and what effect these methods have on the retention of prosthesis during the definitive cementation.MATERIALS AND METHODSForty implant fixture analogues and abutments were embedded in resin blocks. Forty cast crowns were fabricated and divided into 4 groups each containing 10 implants. Group A was cemented directly with the definitive cement (Cem-Implant). The remainder were cemented with provisional cement (Temp-Bond NE), and classified according to the method for cleaning the abutments. Group B used a plastic curette and wet gauze, Group C used a rubber cup and pumice, and Group D used an airborne particle abrasion technique. The abutments were observed using a stereomicroscope after removing the provisional cement. The tensile bond strength was measured after the definitive cementation. Statistical analysis was performed using one-way analysis of variance test (α=.05).RESULTSGroup B clearly showed provisional cement remaining, whereas the other groups showed almost no cement. Groups A and B showed a relatively smooth surface. More roughness was observed in Group C, and apparent roughness was noted in Group D. The tensile bond strength tests revealed Group D to have significantly the highest tensile bond strength followed in order by Groups C, A and B.CONCLUSIONA plastic curette and wet gauze alone cannot effectively remove the residual provisional cement on the abutment. The definitive retention increased when the abutments were treated with rubber cup/pumice or airborne particle abraded to remove the provisional cement.

“…These temporary cements must be removed from the dentine surface prior to definitive cementation; however, it is difficult to eliminate all of the materials from the dentine surface. 8 The presence of residual temporary cements and debris on prepared abutment teeth might have a negative effect on the performance of definitive self-adhesive cements by interfering with the penetration of adhesive monomers into the tooth substrate. Previous studies have examined the effects of the application of temporary cements on the bond strength of subsequent tooth-coloured restorations to dentine.…”

“…Mechanical cleansing protocols included the use of pumice aided with rotary instrumentation, air polishing and air-abrasion with abrasive particles, the use of excavator, airscaler and sonic toothbrush [30]. On the other hand, chlorhexidine digluconate, sodium hypochloride, ethanol containing agents, hydrogen peroxide and polyacrylic acid applications have been proposed as chemical cleansing agents.…”

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...
