introduction: the horizontal bony canal in the lateral maxillary wall is the site of anastomosis between the arterial branches from the posterior superior alveolar artery (psaa) and the infraorbital artery. this anatomic structure is known as the ‘alveolar antral artery’.   materials and methods: we performed a literature review. the anatomic location of the alveolar antral artery in the latera...

flow passing through lateral intakes and channel junctions is turbulent. sediment flow and bed forms areaffected by these flow patterns and vice versa. in this research, a laboratory study was carried out toexplore a possible method for sediment control for a set of submerged vanes and a single spur dikesimultaneously. since a larger portion of the near-bed flow was diverted, the intake receive...

the hydrodynamic behavior of approaching flow and the amount of sediment entry into right-angled lateral intakes in diversion dams were investigated using a laboratory channel by experimental measurement and observation. the velocity field upstream of the intake in the main channel and before it at the sluice gate was measured at different elevations of flow at different discharge rates of the ...

results both counterforce straps were effective. however, significantly more improvement was observed in pain and grip strength after using the newly modified orthosis (p < 0.05). conclusions the newly designed strap reduces pain more effectively and improves grip strength by causing greater localized pressure on two regions with different force applications (two component vectors versus one). ...

purpose: controversy has recently risen about the presence of compensatory ocular countertorsion (coct) after head tilt. this study was performed to define the functional range of this phenomenon. methods: cycloplegic autorefraction was performed on 80 eyes with regular astigmatism 2d. objective autorefraction was performed in normal position, right and left head tilt positions of 5º, 10º, 15º,...

a 20-year-old man presented with the history of pain and swelling in the anterior maxillary segment. the periapical radiography was indicative of a dental anomaly in right maxillary lateral incisor. due to the insufficient information from conventional radiography, cone-beam computed tomography (cbct) was ordered. cbct showed apical root resorption, large apical lucency and two separate canals ...

the aim of this case report was to describe the clinical management of an unusual dens invaginatus type 3. a case of dens invaginatus in a maxillary lateral incisor with a periapical lesion is reported. the patient presented with pain and localized swelling. despite the complex anatomy and diagnosis of dens invaginatus, non-surgical root canal treatment was performed successfully. key learning ...
