“…13 A correlation between marginal adaptation and microleakage could be expected, since poor adaptation could facilitate the penetration of fluids, bacteria and bacterial by-products. 24 Nevertheless, Romão and others 25 demonstrated no correlation between cement thickness and microleakage. In the current study, a shoulder finish line that reduce poor marginal adaptation of ceromers when compared to marginal gaps produced by chamfer finish line specimens was used.…”

Clinical RelevanceOne of the advantages reported for indirect composite restorations is the reduction of polymerization shrinkage, which could produce better marginal sealing. Although sealing of cervical enamel margins was slightly better for the indirect systems used, no difference between indirect and direct restorations was found for cervical margins in cementum/dentin. SUMMARYThis study compared microleakage between indirect composite inlays and direct composite restorations. Forty-eight standard inlay MOD cavities, with cervical margins located either in enamel or dentin, were prepared in extracted human third molars. The specimens were randomly divided into 3 groups (n=16). In the control group, the cavities were restored with the composite Filtek Z250 (3M ESPE). For the experimental groups, indirect restorations were made with the Artglass (Heraeus-Kulzer) or Belleglass HP (Kerr Laboratories) systems and cemented with the dual curing cement RelyX ARC (3M ESPE). The adhesive system Single Bond (3M ESPE) was applied on all groups. The specimens were submitted to thermolcycling, coated with nail varnish, then immersed in 2% basic fuchsine aqueous solution for 24 hours. The teeth were then sectioned and leakage scores were evaluated (40x), based on a standard ranking. Data were submitted to statistical analysis (Mann-Whitney and Kruskal-Wallis tests) with a 95% confidence level. No statistical difference was found between substrates (p=0.595), and the materials performed similarly in dentin (p=0.482). Direct restorations showed higher leakage than indirect restorations at the enamel margins (p=0.004). Within the limitations of this experimental design, overall leakage was similar between both substrates, while the indirect systems provided a better sealing than direct composites only in enamel.

Shear bond strength of resin cements to human dentin

“…It should be noted that effective resin bonding to some high strength porcelain cores (eg In-Ceram) could not be achieved by the usual etching with hydrofluoric acid because of the lack of pores in the material. 30 Problems with the use of resin cements for luting full crowns include excessive film thickness with some materials, 31,32 marginal leakage because of setting shrinkage, and severe pulpal reactions when applied to cut vital dentine. However, this latter problem may be related more to bacterial infiltration than to any chemical toxicity.…”

Crowns and other extra-coronal restorations: Try-in and cementation of crowns

Having successfully negotiated the planning, preparation, impression and prescription of your crown, the cementation stage represents the culmination of all your efforts. This stage is not difficult, but a successful outcome needs as much care as the preceding stages. Once a restoration is cemented there is no scope for modification or repeat. You have to get it right first time. Decemented crowns often have thick layers of residual cement suggesting problems with either initial seating or cement handling. When the fate of restorations costing hundreds of pounds depends on correct proportioning of cements and the quality of the mix, the value of a well-trained and experienced dental nurse is easy to see. Both dentist and nurse need a working knowledge of the materials they are handling.
