OBJECTIVES The aim of this article is to propose a resin cement cleaning protocol for use before recementing a debonded restoration. STUDY DESIGN Ceramic samples were fabricated from IPS d.sign® and IPS e.max Press® and were treated with hydrofluoric acid etching (HF), or HF+silane (S), or HF+S+adhesive or HF+S+A+resin cement. All samples were placed in a furnace at 650º for one minute in ord...

UNLABELLED Restoration of primary teeth continues to be an important facet of restorative dentistry. In comparison to restorations in permanent dentition, the longevity of those in primary teeth is significantly different for all materials. This makes the assessment of these fillings as a separate group meaningful. As there is lack of supporting clinical data with regard to the restoration of p...

Purpose: To evaluate the effect of using separating medium and its type on the microtensile bond strength of indirect resin composite restoration to dentin clinically. Materials and methods: Standard 24 MOD cavities were prepared in the upper first premolars for the selected patients by one operator and restored using indirect resin composite (Grandio So Inlay System, VOCO, Germany). Inlays wer...

Resin Composites Sandwich restorations and Curing techniques Anders Lindberg, Department of Dental Hygienist Education, Faculty of Medicine, Umeå University, 901 87 Umeå, Sweden. Since the mid-1990s resin composite has been used for Class II restorations in stress-bearing areas as an alternative to amalgam. Reasons for this were the patients’ fear of mercury in dental amalgam and a growing dema...

64 INTERNATIONAL DENTISTRY SA VOL. 12, NO. 2 Although colour as an entity should be regarded as being only one of the many building blocks necessary in the achievement of an aesthetic restorative result, a discordant colour scheme can probably be more devastating to the overall effect than many of the other factors present. It is for this reason that so much time, research and expense has gone ...

A major cause for dental resin composite restoration replacement is secondary caries attributed to Streptococcus mutans. Salivary esterases were shown to degrade resin composites. Hypothesis: S. mutans contain esterase activities that degrade dental resin composites and adhesives. Esterase activities of S. mutans were measured using synthetic substrates. Standardized specimens of resin composit...

A new fluoride releasing resin-ionomer cement was used for bonding of gallium alloy restorations in vitro. Etching, priming, and fluoride releasing resin-ionomer cement were used in the experimental group (ARG), prior to placement of the gallium alloy restorations. Three different controls were used: gallium alloy only (G), no etching, fluoride releasing resin-ionomer cement, gallium alloy (RG)...

Ceramic full crowns can restore lost tooth structure, strength, and esthetics but remove about twice as much tooth as an onlay design. Onlay restorations can maintain facial enamel for long-term esthetics, preserve the dentogingival junction for optimum periodontal health, and use supragingival margins for predictable adhesive dentistry. Metallic onlays can create fracture strength 3 times that...

The objective of this study was to compare the clinical performance of a stror.~.tium glass-filled composite resin (Profile ®) and an amalgam alloy (Ease®) in primary molars. A total of 111 restorations (61 composite resin, 50 amalgam) were placed in 37 children. The PHS Clinical Rating Syste~n was used to evaluate color match, cavosurface marginal discoloration, anatomic form, marginal adaptat...
