The indictment alleges that the charges for failure to file are the result of Turley’s non-filing of his 2002 and 2003 income tax returns. In fact, Turley has not filed an individual Income Tax Return for the years 1997 to 2007. The charges for failure to pay are alleged to be the result of Turley not turning over his employees’ payroll taxes to the government. During all four quarters of the years 2003 through 2007, Turley deducted and collected payroll taxes from the total taxable wages of his employees. By failing to remit the monies to the government, his employees did not get credit for the Social Security and Medicare taxes they paid. The indictment further alleges that Turley used these stolen monies to pay for personal living and family expenses.

The literature demonstrates that conventional luting of metal-based restorations using zinc phosphate cements is clinically successful over 20 years. This study compared the clinical outcomes of metal-based fixed partial dentures luted conventionally with zinc phosphate and self-adhesive resin cement.


The self-adhesive resin cement performed clinically as well and can be used as easily as zinc phosphate cement to retain metal-based restorations over a 38-month observation period.

MedPage Today finds a small study shows that it may strain their anterior shoulders more than an overhand throw. Softball pitchers, who underwent photographic motion analysis and surface electromyography analysis of their biceps, were found to have an increased risk of injury to their biceps, caused by increased "peak biceps brachii muscle activation during the windmill pitch." It's a pretty violent motion, and now there's data to back up how traumatic it has the potential to be.

Results: For PPC1 and PPC5, most of the participants recommended management without crown removal (p < 0.05). For PPC6, there was wide disagreement about management (p = 0.81). For all other PPCs, the majority of participants chose to remove the crown before making a treatment decision (p < 0.05). Logistic regression analysis showed that the size of the lesion, vitality of the tooth, participants' age as well as the undergraduate training background of dentists were factors that affected treatment decisions. Conclusion: The data showed a lack of agreement among dentists regarding the management of recurrent caries around crown margins. Size of the lesion, vitality of the tooth, educational training and experience appeared to be the main factors that affected their decisions.
