The objective of this double-masked, parallel-group, multicenter, inpatient study was to compare bromfenac with an acetaminophen/oxycodone combination and ibuprofen in patients who had pain due to abdominal gynecologic surgery. In the 8-hour, single-dose phase, 238 patients received single oral doses of bromfenac (50 or 100 mg), acetaminophen 650 mg/oxycodone 10 mg, ibuprofen 400 mg, or placebo. In the multiple-dose phase, 204 patients received bromfenac, acetaminophen/oxycodone, or ibuprofen for up to 5 days. In the single-dose phase, both bromfenac doses produced peak analgesic responses equivalent to acetaminophen/oxycodone, but the responses to bromfenac were longer lasting. Bromfenac produced significantly better overall (8-hour) analgesic summed scores than acetaminophen/oxycodone. Ibuprofen was less efficacious than the other analgesics. The remedication rate was lower in both bromfenac groups than in the other treatment groups. The acetaminophen/oxycodone group reported more somnolence and vomiting. Single doses of bromfenac provided analgesia at least equivalent to that of the acetaminophen/oxycodone combination, with a longer duration of action. Both doses of bromfenac and acetaminophen/oxycodone were superior to ibuprofen in this study.

Application of management engineering techniques.

Management engineering techniques have proven to be beneficial tools in the analysis and improvement of a medical organization's productive resources. Though used more extensively in the hospital setting, the techniques can be applied to medical groups as a means to furthering the quality of patient care while improving the utilization of resources. An overview of the concept of management engineering is presented through the definition of basic techniques and the illustration of projects employing these methods in the medical group practice setting.

Office of the future. Clinic style.

With technology as the driving force, there are many changes occurring in medical group offices. The medical office of the future is a concept which encompasses the total office -- the interrelationship of all pieces of equipment. This focus on the total office will mean improved productivity and effectiveness not only in clerical areas, but in managerial and physician areas as well. The author examines some of the technology that is being developed today in voice and text processing and communication. Each medical group must analyze its present and future needs and then implement advanced concepts to meet those needs.

The influence of dental alloys on three-body wear of human enamel and dentin in an inlay-like situation.

This in vitro study evaluated the effect of metal alloys on three-body wear resistance of enamel and dentin, and vice versa. Three-body wear of human enamel, dentin, a soft gold alloy (BiOcclus Inlay), a CoCr alloy (Remanium 2000), a resin cement (Variolink II) and a zinc oxide phosphate cement (Harvard) was investigated using the ACTA-machine. Sample chambers of eight sample wheels were prepared with pure materials or combinations of human tooth substance, alloys and cement, simulating an inlay-like situation. After 100,000 and 200,000 cycles in a millet suspension with a spring force of 20 N, the amount of abraded material was profilometrically measured and evaluated by 3D surface data analysis. After 200,000 cycles, the materials demonstrated a mean loss of 0.41 microm for CoCr, 51 microm for gold, 57 microm for enamel, 164 microm for dentin, 79 microm for Variolink and 369 microm for Harvard. Using ANOVA and the Games-Howell-test, resin cement, enamel and gold were a subset not shown to differ, as was zinc phosphate cement and dentin. CoCr demonstrated the least wear and differed significantly from all materials. Enamel wear was significantly reduced in mixed chambers with CoCr, and gold after 200,000 cycles compared to enamel in pure chambers. In summary, a soft gold alloy can be recommended for inlays when considering three-body abrasion since the wear rate of the "soft" gold alloy corresponded to that of human enamel.

Effect of admixed indium on the clinical success of amalgam restorations.

The purpose of this study was to clinically evaluate two formulations of a dispersed-phase, high-copper dental amalgam alloy (Indisperse), which contained admixed indium. One alloy tested contained 5% indium, and the second alloy contained 10% indium. A similar alloy without indium, Dispersalloy, was also placed for comparison. Over the course of the five-year study, there were no differences clinically or statistically regarding texture and luster. The margins of the restorations containing indium incurred slightly less fracture than the non-indium-containing restorations; however, these differences were not clinically significant. It can be concluded that the admixture of 5-10% indium as well as the increased ratio of eutectic spheres to lathe-cut particles found in the indium alloys enhance the clinical performance of amalgam restorations.

Mercury vapor release during insertion and removal of dental amalgam.

During a clinical simulation of insertion and removal of dental amalgams, mercury vapor levels increased slightly, but never exceeded the TLV of 0.05 mg/m3. The addition of indium to dental alloy did not affect the amount of mercury vapor released under these conditions.

Factors associated with clinical success of cervical abrasion/erosion restorations.

The purpose of this study was to evaluate the clinical performance of class 5 restorations according to USPHS criteria. Twenty-five patients and 116 abrasion/erosion lesions were restored with either a glass-ionomer cement restoration (Ketac-Fil), a composite resin restoration with a dentin bonding agent (Silux Plus, Scotchbond 2), or a composite resin restoration with a dentin bonding agent and a glass-ionomer liner (Silux Plus, Scotchbond 2, Vitrebond). At 3 years, 24 patients and 110 teeth were evaluated. All restorations were rated clinically acceptable for color match, cavosurface discoloration, surface texture, and caries development. Glass-ionomer cement restorations demonstrated a slightly rougher surface texture than the composite restorations (Friedman Two-way ANOVA, P=0.000). Significant differences were found with retention (Cochran Q test, P=0.012). Percentages retained were: glass ionomer, 97.3% (36/37); composite/dentin bonding agent, 75.7% (28/37); composite/dentin bonding agent/glass-ionomer liner, 100% (36/36). At 3 years class 5 restorations of glass-ionomer cement or composite with a dentin bonding and a glass-ionomer liner demonstrated significantly better retention than restorations of composite with a dentin bonding agent. Increased occlusal function, mobility, and mandibular arch were associated with a decrease in retention rate.
