OBJECTIVE To describe a novel spinous process-splitting hemilaminoplasty technique for the surgical treatment of intradural and posterior epidural lesions that promotes physiological restoration. METHODS The spinous process was split, the area of the facet lamina junction was drilled, and en bloc hemilaminectomy was then performed. After removing intradural and posterior epidural lesions, we ...

PURPOSE To measure histomorphometrically the location of the peripapillary arterial circle of Zinn-Haller (ZHAC) and assess its associations with axial length. METHODS Using a light microscope, we measured the distance from the ZHAC to the peripapillary ring (optic disc border), the merging point of the dura mater with the posterior sclera ("dura-sclera point"), and the inner scleral surface....

introduction : root-end preparation and restoration with an endodontic material are required when nonsurgical endodontic retreatment has failed or is impossible. the present clinical study reports the treatment outcomes of periradicular surgery using calcium-enriched mixture (cem) cement. materials and methods: a prospective outcome study of periradicular surgery using cem was conducted on 14 p...

missing of mandibular second premolar is one of the most common types of tooth agenesis. in such cases, maintenance of the primary second molar, if possible at all, can prevent many treatment procedures in future. the present case report represents the endodontic management of a necrotic left mandibular primary second molar that had developed an abscess. considering the missing of the permanent...

Background: Thalassaemia is the single most common gene disorder in the world and represents major health burden. The most common oral and craniofacial manifestations are enlargement of maxilla, bossing of the skull and prominent malar eminences. The aim of the study was to assess the radiological changes of the oral and craniofacial region in β thalassaemic children with in the age group of 12...

OBJECTIVES To evaluate the accuracy of using routine 2-dimensional (2D) radiographs (panoramic and periapical) when evaluating the position of orthodontic temporary anchorage devices (mini-implants) in the maxilla, and to compare the results to 3-dimensional cone-beam computed tomography (CBCT). METHODS This cross-sectional study was conducted at King Abdulaziz University, Faculty of Dentistr...

The authors evaluated the imaging performance of cone-beam computed tomography (CBCT) for dental use using 3DX multi-image micro-CT (Morita Co., Kyoto, Japan) and four-row multi-detector helical computed tomography (MDCT) using an Asteion (Toshiba, Tokyo, Japan). A dried right maxillary bone was cut into eight slices 2 mm thick toward the zygomatico-palate and used as a phantom. Images of the p...
