Termites cause major economic losses by destroying agricultural crop trees. This study aims to survey the arboreal tree termites in Komkom community of Oyigbo Niger Delta. The area was divided into 10 zones and 306 trees were examined for presence termite nests, hollow sounds mud tubes. Samples with its nest, hollow, tube cuttings collected from infested using metal spatula, sorted identified. ...

objectives: this study aimed to assess and compare the apical sealing ability of herofill® soft-core system and lateral condensation technique in fine curved canals using the fluid filtration method. materials and methods: forty human mesiobuccal root canals of mandibular first molars with 25° to 40° curvatures were instrumented to an apical size 30/0.04. roots were randomly assigned to two exp...

introduction: the aim of this study was to evaluate the root canal morphology of mandibular first and second molars using cone-beam computed tomography (cbct) in northern iranian population and also to indicate the thinnest area around root canals. methods and materials: we evaluated cbct images of 154 first molars and 147 second molars. by evaluating three axial, sagittal and coronal planes of...

Temporal hollowing occurs to varying degrees after pterional craniotomy. The most common cause of temporal hollowing is a bony defect of the pterional and temporal regions due to the resection of the sphenoid ridge and temporal squama for adequate exposure without overhang. The augmentation of such bony defects is important in preventing craniofacial deformities and postoperative hollowness. Te...

The tear trough or infraorbital hollow is a challenging area to treat, and only a few fillers are suitable for this delicate area. We report on a European case series of six subjects with mild to severe tear troughs who received treatment with cohesive polydensified matrix (CPM(®)) technology hyaluronic acid gel (Belotero(®) Balance). The product was injected as small depots (up to ten small bo...

BACKGROUND/AIMS The sternocleidomastoid (SCM) partial thickness muscle flap is among the various methods described to correct parotidectomy defects, but its indications and limitations are not clearly demonstrated in several reports. This study was done to test the aesthetic outcome of this method, its indications and limitations. The technique was combined with a face lift incision to further ...

apical extrusion of debris and irrigants during cleaning and shaping of the root canal is one of the main causes of periapical inflammation and postoperative flare-ups. the purpose of this study was to quantitatively measure the amount of debris and irrigants extruded apically in single rooted canals using two reciprocating and one rotary single file nickel-titanium instrumentation systems.sixt...
