“…7,8 Few studies that have assessed treatment of sound dentin with CPP-ACP followed by adhesive procedures, noted that the CPP-ACP pastes do not decrease the bond strength. 9,10,11 Alternatives aiming at improving the quality of the adhesive interface have been considered by some authors. Of these, the use of Nd:YAG (neodymium-doped: yttrium aluminium garnet) laser is gaining popularity.…”

The purpose of this study was to investigate the effect of CPP-ACP treatment and Nd:YAG laser on microtensile bond strength (µTBS) of softened dentin. Sixty samples were obtained from thirty sound third molars. All samples were submitted to dentin softening procedure, by the immersion of the specimens in 30 mL of Sprite Zero for 30min. Afterwards, the samples were randomly divided according to the CPP-ACP treatment: CG-Control group; MP-treated with CPP-ACP paste (MI Paste); MPP-treated with CPP-ACP+900 ppm NaF paste (MI Paste Plus). Each group was further divided according to bonding procedure: NL-No laser; L-Laser irradiation after adhesive application and before polymerization. The laser parameters used were 1.4 W, 10 Hz, 140 mJ/pulse, with an optic fiber of 320 µm, generating energy of 174 J/cm 2 per pulse. All samples were restored with Clearfil SE Bond/Filtek Z350 XT. After 24 h, the restored samples were cut into beams (± 1 mm 2 adhesive interface area) and subjected to a µTBS test. Data were analyzed by two-way ANOVA test and Holm-Sidak post-hoc method (α = 0.05). The treatment with CPP-ACP pastes did not significantly affect softened dentin µTBS (p = 0.070). Statistic revealed significant reduction on µTBS values for CG/L, leading to the rejection of the second null hypothesis (p < 0.001). Both CPP-ACP based pastes did not affect µTBS of softened dentin for the adhesive system utilized. The Nd:YAG laser irradiation after application of adhesive system did affect µTBS values of softened dentin samples untreated with CPP-ACP based pastes.

“…Adebayo et al reported that dentin pretreatment with a CPP‐ACP paste did not affect the resin–dentin interfacial morphology and dentin bond strength of a 2‐step self‐etch adhesive system . Borges et al also revealed that CPP‐ACP application had no effect on the bond strength of Clearfil SE Bond and Filtek P90 self‐etch systems but improved the bond strength of Adper SE Plus adhesive . Sattabanasuk et al reported that the bond strength of 3‐step etch‐and‐rinse adhesive system (OptiBond FL; Kerr Dental, Orange, CA) was compromised after CPP‐ACP pretreatment because of the presence of residual precipitates on the dentin surface that remained even after phosphoric acid treatment .…”

“…This thin membrane‐like coating detected on the dentin surfaces after CPP‐ACP treatment might prevent the subsequent acid attack and impair the resin cement‒dentin bond strength . Several studies have evaluated the effect of CPP‐ACP paste pretreatment on the bond strength of adhesive systems . Most applied CPP‐ACP paste just before the etching process of etch‐and‐rinse adhesives because it was assumed that the application order of etching, priming, and bonding is essential in the bonding procedure of etch‐and‐rinse adhesive systems for ideal bond strength .…”

Purpose To evaluate the effect of the application sequence of casein phosphopeptide‐amorphous calcium phosphate (CPP‐ACP) paste (MI paste) on shear bond strength (SBS) of 2 etch‐and‐rinse resin cements to dentin. Materials and Methods Sixty extracted human maxillary premolars were cut to expose the mid‐coronal dentin surfaces. The teeth were randomly divided into 6 groups (n = 10), based on the resin cement used and CPP‐ACP application. In groups 1‐3, Excite DSC/Variolink II and in groups 2‐4, One‐Step Plus/Duolink was bonded to dentin. There were 3 groups for each cement as follows: with no treatment as a control; 3‐minute application of CPP‐ACP before acid etching (CPP‐ACP/Etching); 3‐minute application of CPP‐ACP after acid etching (Etching/CPP‐ACP). After storage in distilled water at 37°C for 24 hours, SBS test was performed. Data were analyzed with 2‐way ANOVA and post‐hoc Tukey test (α = 0.05). Results CPP‐ACP application on the dentin before and after acid etching significantly decreased the SBS of OS/Duolink (13.60 and 14.71 MPa, respectively vs. control; 21.21 MPa, p < 0.001); however, it did not influence the SBS of Excite DSC/Variolink II (25.14 MPa) before acid etching (27.37 MPa) or after acid etching (26.41 MPa, p > 0.388). The application sequence of CPP‐ACP did not influence the SBS of etch‐and‐rinse resin cements evaluated. Conclusion CPP‐ACP applications may lower the SBS in some etch‐and‐rinse resin cements, and timing of applications makes no difference.

Objective: The aim of the present study was to compare the effect of pre-treating dentin with chlorhexidine, at concentrations of 0.2% and 2%, and remineralizing paste containing CPP-ACP (MI Paste – GC) on the bond strength of adhesive systems. Material and methods: In total, 80 slides of dentin were used. These slides were 2 mm thick and were obtained from bovine incisors. Standard cavities were created using diamond bur number 3131. In the control groups, a Scotchbond Universal Adhesive (SUA) self-etching adhesive system of 3M ESPE and a Clearfil SE Bond (CSE) adhesive system of Kuraray were applied, following the manufacturer’s instructions. In the other groups, dentin was pretreated with chlorhexidine (0.2% and 2%) for 1 min and with MI Paste for 3 min. The cavities were restored with Z350 XT resin (3M ESPE). After 24 h of storage, the push-out test was applied at a speed of 0.5 mm/min. Results: The different dentin pretreatment techniques did not affect the intra-adhesive bond strength. There was a difference between treatment with MI Paste and chlorhexidine 0.2% in favor of the SUA, with values of 15.22 and 20.25 Mpa, respectively. Conclusions: The different pretreatment methods did not alter the immediate bond strength to dentin. Differences were only recorded when comparing the adhesives.
