Service-oriented systems are becoming more and more nodes in a digital, dynamic ecosystem requiring the identification and establishment of flexible, spontaneous collaboration activities between services. This requires new engineering approaches that can integrate new functionalities and behaviours into existing running systems of active, distributed and(More)
INTRODUCTION The purpose of the study was to compare the accuracy of the Root ZX electronic apex locator (J Morita Corp, Tokyo, Japan) between an in vivo and an in vitro model. METHODS The working length (WL) was determined electronically for 46 root canals of human teeth with a 15 K-file using both in vitro (n = 23) and in vivo (n = 23) models. The files(More)
There is a large body of research on software services, but the issues of communication and dynamic reconfiguration have received little attention, as have adaptation to environment and dynamic combination of service building blocks into new applications. Here, we present the approach of the FP7 ALIVE project to the use of formal models of coordination and(More)
OBJECTIVES To compare the efficacy of Reciproc(®) (VDW GmbH) and ProFile(®) (Dentsply Maillefer) instruments at removing gutta-percha from straight and curved root canals ex vivo filled using the cold lateral condensation and GuttaMaster(®) (VDW GmbH) techniques. MATERIAL AND METHODS Forty mesial roots of mandibular molars with two curved canals and 80(More)
INTRODUCTION Raypex 6 is an electronic apex locator (EAL) that has not yet been tested in vivo. The purpose of this in vivo study was to compare the accuracy of two EALs: the Dentaport ZX and the Raypex 6. METHODS The study involved 36 straight single-rooted teeth. A 10-K file was advanced until the EAL detected the major foramen. The file was fixed in a(More)
OBJECTIVES This study attempted to find a simple adhesive restorative technique for class I and II cavities on posterior teeth. STUDY DESIGN The tested materials were a self-etching adhesive (Parabond, Coltène/Whaledent) and a dual-cure composite (Paracore, Coltène/Whaledent) used in bulk to restore the cavities. Class II MO cavities were performed and(More)
