Clinical considerations for reattachment of tooth fragments.

Trauma to anterior teeth is relatively common among children and teenagers; it has been estimated that approximately one quarter of the population under the age of 18 years sustain traumatic injury in the form of anterior crown fracture. Reattachment of a fractured fragment to the remaining tooth can provide esthetically pleasing results provided that the fragment is available. In this report, a systematic clinical approach through evaluation of periodontal, endodontic, coronal, and occlusal aspects is presented to help dentists analyze the factors affecting selection of techniques and materials. In addition, use of adhesive materials for tooth fragment reattachment is illustrated. Modifications of the reattachment process, including placement of veneer and radicular post, are also discussed.

Materials and techniques for achieving clinical excellence with indirect composite restorations.

Indirect resin restoration technology continues to grow at an unbelievable rate. This article has outlined some of the materials available within this category. There are others that the author has not had the opportunity to work with. At this time, the author believes the primary indication for the use of this class of material is esthetic inlays and onlays as well as a well-planned conservative [figure: see text] fixed partial denture in a low stress area. If unclear about the best material to use in a given situation, the dentist should consult the laboratory technician to discuss the technician's experience and confidence with the different systems. Many times the physical properties of the material are not as important as the ability of the technician and his or her experience with the different handling properties of the available systems when examining the short-term and long-term success of the restoration.

Achieving aesthetic excellence through an outcome-based restorative treatment rationale.

The conceptual basis of restorative-driven implant dentistry is well established among clinicians. Its implementation includes the development of a prosthetic blue-print that will serve as a guide throughout therapy. While these concepts may be applied to prosthetic dentistry in general, their benefits are most compelling in the treatment of the aesthetic zone. This article demonstrates a systematic multidimensional approach for the establishment and incorporation of definitive aesthetic objectives throughout the diagnostic, adjunctive, and restorative treatment phases.

Influence of ZOE temporary restorations on microleakage in composite restorations.

This study investigated the influence of zinc-oxide eugenol (ZOE) temporary restorations on microleakage in composite restorations. Class V cavities were prepared on the buccal surfaces of 32 freshly extracted, non-carious human premolars. The teeth were randomly divided into four groups of eight teeth. Specimens in Group 1 (control) received no temporary restoration. Group 2 and 3 specimens were covered with IRM (Type III ZOE cement) mixed at powder:liquid (P:L) ratio of 10g:1g and 10g:2g, respectively. Specimens in Group 4 were covered with poly-carboxylate cement (eugenol-free) mixed at a P:L ratio of 2.85g:1g. The temporary restorations were removed mechanically with an ultrasonic scaler after one week storage in distilled water at 37 degrees C. The preparations were washed and restored with Scotchbond Multi-Purpose Plus and Z100 according to manufacturers' instructions. The restorations were finished, thermally stressed for 400 cycles and subjected to dye penetration testing. Results were analyzed using Kruskal-Wallis and Mann-Whitney tests at a significance level of 0.05. At both enamel and dentin margins, the microleakage associated with Group 3 was significantly greater than for Groups 1, 2 and 4. For Groups 1 and 4, leakage at the dentin margins was significantly greater than in enamel margins. For the groups pretreated with IRM, no significant difference in dye penetration scores was observed between enamel and dentin. Pre-treatment with IRM mixed at a P:L ratio of 10g:2g significantly increased microleakage and is not recommended clinically.
