background : dental unit waterlines (duwls) are ideal nvironment for development of microbial biofilms. microbial contamination of water in duwls is thought to be the result of biofilm formation as it could serves as a haven for pathogens. the aim of this study was to assess microbial quality of water in dental unit waterlines of dental units located at the dental school of isfahan university o...

AIM To illustrate the conceptual basis and the operative procedure of the Anatomic Endodontic Technology (AET) technique and to illustrate the specific instruments used in each phase. SUMMARY The basic characteristics of the AET technique are reported. The instruments and procedure are described in three phases: coronal access, coronal-middle preparation and apical preparation. In the first p...

BACKGROUND Spinal cord injury patients walk with a flexed trunk when using reciprocating gait orthoses. Reduction of trunk flexion during ambulation may produce an improvement in gait parameters for reciprocating gait orthosis users. OBJECTIVES To investigate the effect on kinematics and temporal-spatial parameters when spinal cord injury patients ambulate with an advanced reciprocating gait ...

JCO/AUGUST 2004 T of a palatally impacted maxillary permanent canine often involves surgical exposure of the tooth, followed by orthodontic repositioning.1-10 After the elevation of a palatal flap, the overlying bone is usually removed with electric or manual instruments. This article presents an alternative method that uses piezoelectricity to minimize trauma to the impacted tooth and the surr...

The effects of three dissolving agents on the accuracy of an electronic apex locator- (EAL-) integrated endodontic handpiece during retreatment procedures were evaluated. The true lengths (TLs) of 56 extracted incisor teeth were determined visually. Twenty teeth were filled with gutta-percha and a resin-based sealer (group A), 20 with gutta-percha and a zinc oxide/eugenol-based sealer (group B)...
