“…As far as the choice of the adhesive strategy is concerned, prior, welldocumented studies assessing the bond strength of a composite to MTA suggested the superiority of the TE technique over the SE systems. [15][16][17] However, reports on similar studies regarding Biodentine are ambiguous.…”

Background. Biodentine ® is a bioactive calcium silicate-based material, with better strength parameters, an easier application method and a shorter setting time than mineral trioxide aggregate (MTA). The bond strength between Biodentine and the composite material is essential for the durability of the layered restoration.Objectives. The objective of this study was to evaluate the bond strength of Biodentine to a resin-based composite at various acid etching times and with different adhesive strategies. Material and methods.In the 1 st part of the experiment, the specimens were divided into 2 groups: the adhesive was applied in the total-etch (TE) and self-etch (SE) techniques. In the TE group, 37% orthophosphoric acid was applied after 30 s (TE 30) and 240 s (TE 240). In the SE group, the SE system was applied for 30 s (SE 30) and 240 s (SE 240). In the 2 nd part, the SE systems Clearfil ® SE Bond and Clearfil S3 Bond Plus were evaluated (the CSE and CS3 groups, respectively). In each group, the adhesive system was applied in 1 (the CSE 1 and CS3 1 subgroups) or 2 layers (the CSE 2 and CS3 2 subgroups). The specimens were subjected to a shear bond strength (SBS) test in a universal testing machine.Results. Shear bond strength was higher after a prolonged etching procedure in the TE (TE 30: 2.51 MPa, TE 240: 9.39 MPa) and SE techniques (SE 30: 5.92 MPa, SE 240: 7.89 MPa). A statistically significant influence was detected in relation to 30 s of surface preparation time for Clearfil S3 Bond Plus (p < 0.001). Greater bond strength was revealed after the application of 1 layer of the Clearfil S3 Bond Plus single-bottle system (CS3 1: 6.42 MPa). Conclusions.The SBS of Biodentine to the composite depends on both the etching time and the mode of application of the adhesive systems. Higher bond strength was obtained for the SE adhesive in a shorter application time.

“…Recent studies suggest that placement of composite used with a two-step etch and rinse adhesive (E&R) over white MTA performed significantly better than an all-in-one system in terms of bond strength [76]. Other studies concluded that the highest bond strength was obtained when the E&R adhesive was used after 24 h resulting in shear bond strength (SBS) of 7.3 ± 1.49 MPa [77,78]. Supplementary surface treatment protocols were investigated to reliably asses SBS after final composite restoration (Table 3).…”

Bio-Inductive Materials in Direct and Indirect Pulp Capping—A Review Article

2020

The article is aimed at analyzing the available research and comparing the properties of bio-inductive materials in direct and indirect pulp capping procedures. The properties and clinical performances of four calcium-silicate cements (ProRoot MTA, MTA Angelus, RetroMTA, Biodentine), a light-cured calcium silicate-based material (TheraCal LC) and an enhanced resin-modified glass-ionomer (ACTIVA BioACTIVE) are widely discussed. A correlation of in vitro and in vivo data revealed that, currently, the most validated material for pulp capping procedures is still MTA. Despite Biodentine's superiority in relatively easier manipulation, competitive pricing and predictable clinical outcome, more long-term clinical studies on Biodentine as a pulp capping agent are needed. According to available research, there is also insufficient evidence to support the use of TheraCal LC or ACTIVA BioACTIVE BASE/LINER in vital pulp therapy.

“…Concerning resin modified glass ionomer, Alqahtani et al (4) had mentioned that when Fuji II LC resin modified glass ionomer was immediately placed on ProRoot MTA it revealed statistically higher shear bond strength than the delayed placement. Several studies (4,(28)(29)(30)(31) had correlated the relatively strong bond of resin modified glass ionomer to the unset MTA based material could be related to the ability of formation of chemical bonding between the carboxylate anions (RCOO−) in the polyacrylic acid and the calcium in the MTA during its setting. On the contrary, those studies had declared that the premixed bio-ceramic (Neoputty) had responded in a contradictory way to either ProRoot MTA or NeoMTA2 concerning the immediately placed resin modified glass ionomer; as Neoputty had revealed lower shear bond strength values on being immediately restored compared to the delayed restoring.…”

“…This was attributed to the need of the premixed bio-ceramic Neoputty for moisture from external sources to start the setting reaction. (4,(28)(29)(30)(31) Thus, when dealing with premixed bio-ceramics it was found not preferable to immediately place the resin modified glass ionomer on top. Consequently, in accordance to the recommendations of the previously conducted researches, the present study went through the delayed restoration technique, and NuSmile-Neoputty specimens were left stored for 7 days before placement of the restorative materials.…”

Objective:The study aimed to assess the shear bond strength of four restorative materials that are widely used in pediatrics to NuSmile-Neoputty material. The restorative materials were two glass ionomers: Fuji II LC and Equia Forte Fil, and two dental resin composites: Cention N and Venus Bulk Fill. Materials and methods:A total of 164 specimens were used in the study. 160 specimens were used for the shear bond strength testing and failure mode analysis. Four specimens were needed for scanning electron microscopic investigation of NuSmile surface with and without application of MDP containing adhesive. Specimens were divided into four groups according to the restorative material bonded to NuSmile: Group I: Fuji II LC. Group II: Equia Forte Fil. Group III: Cention N. Group IV: Venus Bulk Fill. Further subdivision into two subgroups (A & B) was done according to application of the adhesive or not respectively.Results: Subgroups (IA) and (IIIA) revealed significantly higher shear bond strength values than other groups with no significant difference between them, followed by subgroup (IVA). Subgroup (IIA) revealed the least bond strength value. Conclusions:Fuji II LC glass ionomer and Cention N composite would be capable for inducing stronger bond with NuSmile-Neoputty compared to Venus Bulk Fill composite. On the contrary, the bond strength of Equia Forte Fil to NuSmile-Neoputty could not be considered satisfactory. Application of MDP containing adhesive can enhance the bond strength to Nusmile-Neoputty regarding Fuji II LC, Cention N, and Venus Bulk Fill.

Bond strength of a resin composite to MTA at various time intervals and with different adhesive strategies

Abstract: Background. MTA cannot be used as a single restorative material due to poor esthetics and mechanical properties. Resin-based composite is often placed on top of MTA. Optimal time of doing that and the most effective bonding strategy have not been clearly determined.
