“…20,22 Therefore, even the hybrid resin composite overlapping uncut enamel adjacent to the cavity margin may easily be fractured by the etiological forces associated with NCCLs, since fracture resistance of resin composites decreases as bond strength decreases. 32,33 This is supported by the results of clinical trials. 11,12,14,30 Another possible explanation is that the evaluation criterion for marginal adaptation is subjective.…”

Objectives: This randomized controlled clinical trial evaluated the 3-year clinical performance of a hybrid (Clearfil AP-X; AP) and a flowable (Clearfil Flow FX; FX) resin composite in 98 non-carious cervical lesions. Methods:Twenty-two patients, 11 male and 11 female (mean age: 61.9 years, range: 29-78 years) regularly visiting the Nagasaki University Hospital, participated in the study. Each patient received both materials randomly. All restorations (48 restorations for AP and 50 restorations for FX) were placed in conjunction with an all-in-one system (Clearfil S 3 Bond) by one dentist. The restorations were blindly evaluated by two examiners at baseline, 6 months, 1, 2 and 3 years using modified USPHS criteria. The data were statistically analyzed using the Cochran's Q test and Fisher's exact test.Results: All the patients were examined at each recall. However, five restorations could not be evaluated at 3-year recall as two teeth had been extracted and three restorations had been lost. The only minor problem was the integrity of the enamel margin. The incidence and extent of marginal staining increased with time, but it was still superficial. Marginal staining occurred adjacent to 11 restorations for AP and 12 restorations for FX after 3 years. Neither lesion size nor depth had influence on marginal staining adjacent to each type of resin composite. There were no significant differences in the clinical performances between AP and FX for each variable. Conclusions:Under the protocol used in this study, both types of resin composite in conjunction with S 3 Bond demonstrated an acceptable clinical performance up to 3 years.

This study sought to evaluate the pH value, film thickness, filler particle percentage, and morphological changes of selfadhesive resin luting cements. Products tested were G-Cem, Maxcem, Smart Cem, and RelyX™ Unicem. Cement pH was measured with pH test paper. Filler particle percentage was calculated after cement samples were incinerated at 750℃. To test film thickness, mixed cements were placed between two glass plates and compressed using a loading device. For morphological changes, specimen surfaces were observed by SEM after treatment with various media. There were significant differences among the cement pH values measured at 20 seconds after light curing, and at 90 seconds and 48 hours after mixing. Filler particle percentage was directly proportional to film thickness. Degradation of cement surfaces was also detected after surface polishing and immersion in water, acetic acid, and acetone. In conclusion, significant differences were found in the surface properties of the materials tested, and these differences might lead to differences in their clinical performance.

“…Moreover, the tensile bond strength of total-etch resin cement was greater than that of self-etch, one-step resin cement, irrespective of whether the cavity was prepared by bur or Er, Cr: YSGG laser. It should be noted that the adhesive bonding of luting cements is closely related to the fracture resistance of restorations 27) . Nevertheless, self-etch resin cements are less technique-sensitive and present less postoperative sensitivity 28) .…”

The purpose of this study was to investigate the tensile bond strength of composite inlays to human dentin with two different cavity preparation tools (bur versus Er, Cr: YSGG laser) and with two different bonding procedures (total-etch: Variolink II versus self-etch: Maxcem). The specimens were divided into four groups: bur-cut/Variolink II, bur-cut/Maxcem, laser-ablated/Variolink II, and laser-ablated/Maxcem. The following characteristics were then investigated: morphological change, dentin-resin cement interface, surface roughness, and tensile bond strength. Results demonstrated that the tensile bond strengths of the four groups were 19.11±5.88 MPa, 8.54±2.38 MPa, 13.72±3.43 MPa, and 12.11±3.71 MPa, respectively. We concluded that Variolink II provided higher tensile bond strength to composite inlays than Maxcem. On the other hand, the bond strength of Variolink II with dentin cavity prepared by Er, Cr: YSGG laser was statistically lower than that prepared by bur.
