This study was conducted to assess the five-year clinical performance of composite restorations using a self-etching primer adhesive system, Clearfil Liner Bond II. Restorations were rated using the following scale: A -Good; B -Clinically acceptable; C -Clinically unacceptable; or D -Already replaced. The ratings were analyzed using Freedman's test p 0.01 and Steel-Dwass test p 0.05 . A total of 83 restorations from 36 patients were identified from treatment records. Twenty-six restorations 31.3 presented A rating and 36 restorations 43.4 were clinically acceptable B rating , while five 6.0 received C rating and 16 19.3 had already been replaced D rating . The mean survival rate of serviceable restorations i.e., combined A and B ratings after five years was 74.7 . It was found that cavity form, including cavity size, and occlusal contact seemed to influence longevity.

Aims-The purpose of this study was to evaluate the effects of photoinitiator type and water content on the polymerization rate (R p ) and degree of conversion (DC) of a model BisGMA/HEMA-based resin.Materials and methods-The comonomer mixture consisted of BisGMA/HEMA (60/40 by weight). Different two-or three-component photoinitiator systems were incorporated. Twocomponent systems were 0.5% CQ (camphorquinone) and 0.5% DMAEMA (2-(dimethylamino) ethyl methacrylate) or 0.5% CQ and 0.5% 4E (Ethyl 4-dimethylaminobenzoate). The threecomponent systems were added 1% DPIHP (diphenyliodonium hexafluorophosphate) to the above systems. Each system was tested as made, or after addition of 5, 10, 15wt% water. When cured under a conventional dental light, the R p and DC of each formulation was determined using time-resolved attenuated total reflection (ATR)-Fourier transform infrared (FTIR) spectroscopy.Results-For mixtures containing two-component initiator systems, when the hydrophobic initiator CQ was used in combination with hydrophilic DMAEMA, R p s and DCs were dramatically decreased as a function of water content. The R p s and DCs of the hydrophobic CQ/4E system were higher than those of the CQ/DMAEMA system in the presence of water. For three-component initiator systems, incorporation of DPIHP enhanced the polymerization of all mixtures in the presence of water compared to their counterpart two-component initiators. Interestingly, the CQ/DMAEMA caused greater DC and Rp when DPIHP was used.Significance-The hydrophobicity/hydrophilicity of photoinitiator components significantly affects both the DC as well as R p when in the presence of water. The results indicate that formulation of photoinitiator components should be based on the effectiveness of the bonding systems under both dry and wet conditions.

“…5,8 The bonding of the resin luting agent to tooth structure is enhanced by acid etching of the enamel and/or dentin and by the use of a dental adhesive. [9][10] The silicate-based ceramic surfaces are etched, often using hydrofluoric acid, which changes its microstructure by dissolution of one of the glassy phases of porcelain and by creating an appropriate microstructure for bonding. [11][12][13][14] Another pre-bonding treatment for ceramic surfaces is airborne aluminum oxide particle abrasion, [15][16] which similarly changes the microstructure of the ceramic surface.…”

SUMMARYObjective. The current study evaluated the micro-shear bond strength between a resin luting agent and four strengthened all-ceramic systems under different surface treatments.Methods. Rectangular specimens of IPS Empress 2 (Ivoclar-Vivadent), Cergogold (DeguDent), In Ceram Alumina (Vita) and Cercon (DeguDent) ceramics were fabricated and randomly divided into three groups: 1-no treatment; 2-etched with 9.5% hydrofluoric acid and 3-airborne-particle abraded with 50 µm aluminum oxide particles. The ceramic surfaces of the specimens were coated with a silane agent (Clearfil Porcelain Bond, Kuraray), then bonded with a resin-luting agent (Panavia F, Kuraray). A micro-shear bond test was carried out to measure the bond strength. Moreover, each ceramic surface was observed morphologically by scanning electron microscopy. The results were submitted to analysis of variance and Tukey's posthoc analysis (p<0.05). SMP Torres • GA Borges • AM Spohr AADB Cury • S Yadav • JA Platt Clinical RelevanceThe bond strength between ceramics and a resin luting agent is affected by the ceramic surface treatment, which is dependent on the ceramic composition. Laboratory ResearchResults. The bond strength of all ceramic systems evaluated was affected by the surface treatments (p<0.05). The highest values for bond strength of IPS Empress 2 were found when the surface treatment used was hydrofluoric acid etching, followed by airborne particle abrasion treatment. On the other hand, airborne particle abrasion treatment and acid etching were not different for Cergogold and In Ceram Alumina ceramics, but they were higher when compared to the control (p<0.05). The highest bond strength to Cercon was found when it was treated with airborne particle abrasion with aluminum oxide. The SEM photographs showed that the hydrofluoric acid etching treatment affected the surface of IPS Empress 2 and Cergogold; however, Cercon and In Ceram surface morphology were not changed by the hydrofluoric acid etching. The airborne particle abrasion treatment altered the Cercon ceramic morphology but it did not change the other ceramic's surface.
