Introduction: Since preserving the structure of treated teeth is a critical success factor, studying the effects of tooth structure loss on fracture resistance of the tooth tissue appears necessary. The aim of this study was to evaluate the consequences of the loss of different tissues regarding fracture resistance of teeth undergoing root canal treatment without the use of indirect restoration...

The Intendant personally enumerated the 3,215 inhabitants of New France with regards to their age, sex, marital status and occupation.

Sternal dehiscence is a recognised complication after median sternotomy, occurring in 0.5-5% of cases with or without infection. A 72-year-old man presenting with collapse and ventricular tachycardia was investigated for a possible acute cardiac event 2 years after coronary artery bypass grafting for ischemic heart disease. Work-up chest X-ray showed displacement of all sternal wires, and compu...

*Correspondence: Laurent Talon, CNRS, FAST, Université de Paris-Sud, Bât. 502, Campus University, Orsay, F–91405, France e-mail: [email protected] We derive the volumetric flow rate vs. pressure drop of a Bingham fluid in one-dimensional channels of variable apertures in the lubrication approximation. A characteristic length scale, a∗ characterizing the flow is introduced in order to disting...

Fig. 1. A photograph captured intraoperatively (a) and schematic representation of QAV (b) as viewed through the aortotomy. The right and left coronary cusps were almost normal in size and had sufficient effective height. While the noncoronary cusp (NCC) was relatively thick and large, the accessory cusp (AC) was too small to independently act as a competent cusp. The raphe between the NCC and ...

A novel sternum stabilization implant system is presented in a complex clinical case with previous pseudarthroses. The authors used the advanced closure system Sternal Talon of KLS Martin group and arranged 1 double and 2 single implants in an atypical fashion to fit the patient's needs. One year later follow up has not revealed any recurrence of pain or pseudarthrotic signs such as crepitation.
