“…It has been reported that the adhesives of the one-bottle systems create thinner adhesive layer than those of the self-etching primer systems. 17,18 Clearly, a thin adhesive layer favors fluoride release from the coated material. Hence, the adhesives of the one-bottle systems which contain solvents may produce thinner layers of adhesive, promoting greater fluoride release from the restorative material.…”

“…In the case of the filled adhesive, the increased viscosity and the role of the oxygen inhibition layer is a major cause of thick bonding layers 6) . Opdam et al 16) reported that thick adhesive layer seems to prevent the formation of interfacial gaps between tooth and restoration and act as a superior elastic buffer compared to thinner layers, whereas Hilton and Schwartz 17) suggested that thick adhesive layer adversely affects bond strengths, increases crack propagation, elevates the thermal co-efficient of expansion mismatch with the tooth and decreases the load bearing and wear component of the restoration.…”

The purposes of this study were to examine the variability of adhesive thickness on the different site of the cavity wall when used total-etch system without filler and simplified self-etch system with filler and to evaluate the relationship between variable adhesive thickness and microtensile bond strength to the cavity wall.A classⅠcavity in six human molars was prepared to expose all dentinal walls. Three teeth were bonded with a filled adhesive, Clearfil TM SE bond and the other three teeth were bonded with unfilled adhesives, Scotchbond TM Multi Purpose. Morphology and thickness of adhesive layer were examined using fluorescence microscope. Bonding agent thickness was measured at three points along the axial cavity wall, edge of cavity margin ( (r ri im m) ), halfway down each cavity wall ( (h hl lf f) ), internal angle of the cavity ( (a an ng g) ). After reproducing the adhesive thickness at r ri im m, , h hl lf f and a an ng g, , micro-tensile bond strength were evaluated.For both bonding agents, adhesive thickness of a an ng g was significantly thicker than that of r ri im m and h hl lf f (P < 0.05). As reproduced the adhesive thickness, microtensile bond strength was increased as adhesive thickness was increased in two bonding agents.Adhesive thickness of internal angle of the cavity was significantly thicker than that of the cavity margin and the halfway cavity wall for both bonding agents. Microtensile bond strength of the thick adhesive layer at the internal angle of the cavity was higher than that of the thin adhesive layer at the cavity margin and the halfway cavity in the two bonding systems.

“…During mastication, saliva and other liquids may enter the gaps under pressure, resulting in detachment of the adhesive interface, or deformation of restoration margins. 2 This in turn may allow further penetration of saliva and microorganisms into the tooth-composite interface, bringing discoloration, hypersensitivity, plaque accumulation, and may potentially lead to the development of a caries lesion, which is the main reason for composite restorations to be replaced. 3 However, this costly procedure can be delayed as long as possible with early detection and monitoring of gap or defect progression adjacent to restorations.…”

Assessment of interfacial defects at composite restorations by swept source optical coherence tomography

Abstract. In clinical dental practice, it is often difficult or even impossible to detect and assess interfacial adhesive defects at adhesive restorations by means of visual inspection or other established diagnostic methods. However, nondestructive optical coherence tomography (OCT) may provide a better picture in this diagnostic scenario. The aim of this study was to evaluate the suitability of swept source OCT (SS-OCT) for the nondestructive assessment of interfacial deficiencies at composite restorations and the evaluation of cohesive defects within composite material. Ten class V composite restorations that were not adhesively luted were taken as validation objects and examined for frequency of interfacial gaps, air entrapments, and defects between composite layers using SS-OCT with a 1325-nm center wavelength. Light microscopy was used to inspect for inherent structures. SS-OCT detected 79.5% AE 1.8% of the total gap lengths at the enamel interface and 70.9% AE 0.4% at the dentin interface. Additionally, defective structures in composite restorations were displayed. It was shown that OCT imaging has the potential to nondestructively assess the interfacial adaptation of composite restorations and to detect internal defects in the layered composite material.
