“…The presence of calcium and phosphate ensures that the material has remineralizing properties [33], resulting in the formation of an intimate bond between the resin and dentin [8]. Resin tag development demonstrates the flow of adhesive resin in the tubules [32], ensuring optimal mechanical interlocking and the development of a firm hybrid layer [34]. In our study, resin tags of varying depth were observed for the EA and HA-10% group when the dentin was conditioned with H 3 PO 4 and PDT.…”

The study aimed to analyze the effect of the addition of nano-hydroxyapatite (nano-HA) particles on the mechanical properties of experimental adhesive (EA). Furthermore, dentin interaction of EA (without nano-HA) and EA with nano-HA (hereon referred to as HA-10%) were also investigated and equated. Methods consisting of scanning electron microscopy (SEM)–energy-dispersive X-ray spectroscopy (EDX), micro-Raman spectroscopy, micro-tensile bond strength (µTBS) test, and Fourier transform infrared (FTIR) spectroscopy were employed to study nano-HA particles shape, dentin bond strength, degree of conversion (DC), and adhesive–dentin interaction. Ninety teeth (N = 90) were collected, and pre-bonding, conditioning of dentin was performed utilizing phosphoric acid (H3PO4) etching, photodynamic therapy (PDT), and ER-CR-YSGG (ECY) laser. The teeth were set to form bonded specimens using two adhesives. Nano-HA particles were spherical-shaped, and EDX confirmed the presence of oxygen, calcium, and phosphorus. Micro-Raman spectroscopy revealed distinct phosphate and carbonate peaks for nano-HA. The µTBS test demonstrated highest values for HA-10% group on the H3PO4 conditioned dentin. The greatest DC was observed for the EA group. The addition of nano-HA-10 wt.% particles in dentin adhesive resulted in improved bond strength. The incorporation also demonstrated acceptable DC (although lower than EA group), suitable dentin interaction, and resin tag formation.

“…Adhesive resin extensions directed/flowing into open dentin tubules are called "resin tags" (6). The structure of these tags varies according to the application technique of acid, the thickness of the remaining dentin, the surface moisture and structure of the dentin.…”

“…The clinical success of composite restorations depends greatly on the adhesive system [1,2]. The bonding mechanism of adhesive systems essentially involves the replacement of minerals removed from hard dental tissues by resin monomers; therefore, the polymer is micromechanically trapped in the dental substrate [13]. The universal bonding is the newest type of bonding that can be used in the total-and selfetching modes.…”

Objectives: This study aimed to determine the microtensile bond strength (μTBS) of a bulk-fill composite to permanent and primary coronal dentin using a universal adhesive in self-etch and total-etch modes. Materials and Methods: This in-vitro study was performed on 52 occlusal dentinal surfaces of human primary and permanent teeth. The crowns were cut to the gingival level. The 48 prepared dentin sections were randomly assigned to the following groups (n=13): A: Primary/Total-etch, B: Primary/Self-etch, C: Permanent/Total-etch, and D: Permanent/Self-etch. In groups A and C, after etching for 15 seconds, two layers of a universal bonding (Futurabond U) were applied and cured for 10 seconds. All samples were filled with a bulk-fill composite (x-trafil; VOCO) and cured for 40 seconds. The samples were cut to a bar-shaped dentin block with the dimensions of 1×1×1 mm3, and after 10,000 thermocycles, the μTBS test was accomplished at a crosshead speed of 1 mm/minute. The mean and standard deviation (SD) of μTBS were calculated, and the data were analyzed using two-way analysis of variance (ANOVA) and Fisher's exact test. Results: The mean μTBS was as follows: A: 15.03±2.0279, B: 11.11±2.4423, C: 23.50±4.8165, and D: 16.26±6.3200 MPa. Futurabond U showed a higher μTBS in the total-etch mode (P<0.001). The permanent teeth had greater μTBS than the primary teeth (P<0.001). Similar percentages of failure modes were observed in the total-etch groups but in the self-etch groups, most failures were in the form of adhesive and mixed. Conclusion: Greater μTBS was observed in the permanent teeth with the total-etch technique.

Scanning electron microscopy analysis of microstructure of the adhesive interface between resin and dentin treated with papain gel

Abstract: When Papacarie® was used prior to the application of a bonding agent it could interfere with the formation of the hybrid layer without changing the length of the tag. Moreover, the morphology in the experimental group was found to be more uniform and regular.
