AIM The aims of this study were to assess the location, morphology and anatomical dimensions of the nasopalatine canal (NPC) on cone beam computed tomographic (CBCT) images and to compare our findings with recent reports on this matter. A detailed knowledge of anatomical variations is mandatory in skeletal surgery of the anterior maxilla. PATIENTS AND METHODS Two hundred CBCT scans of the mid...

BACKGROUND The sagittal diameter of the cervical spinal canal is of clinical importance in traumatic, degenerative, and inflammatory conditions. A small canal diameter has been associated with an increased risk of injury; however, there is a lack of reliable normative data on spinal canal diameters in different age groups in the United States population. The purpose of this study was to use dir...

In this article, we propose a trajectory planning algorithm that enables autonomous surface vessels to perform socially compliant navigation in city's canal. The key idea behind the proposed is adopt an optimal control formulation which deviation of movements vessel from nominal human-operated penalized. Consequently, given pair origin and destination points, it finds trajectories resemble thos...

background: for improving the quality of endodontic performance of practitioners in clinical practice, their basic, preclinical performance and knowledge must be taken into consideration. this study aimed to radiographically evaluate the technical quality of preclinical molar root canal treatments (rcts) performed by undergraduate dental students at a dental school in iran. further, the effect ...

BACKGROUND In this proof-of-concept study, we investigated the effect of the predominantly sensory adductor-canal-blockade on established pain in the early post-operative period after total knee arthroplasty (TKA). We hypothesised that the adductor-canal-blockade would reduce pain during flexion of the knee (primary end point) and at rest, as well as reducing morphine consumption and morphine-r...

background. maximum sealing ability or adhesion of endodontic sealers can be achieved after an effective removal of smear layer. endodontic irrigants assist in adequate removal of smear layer and thus improve the retention mechanism. the aim of this study was to evaluate the effect of two different root canal irrigating solutions (5.25% naocl followed by 17% edta and qmix) on the apical sealing...
