BACKGROUND AND PURPOSE There is a wide range of normal variation is sphenoid sinus development, especially in the size of the lateral recesses. The purpose of this study was to determine imaging characteristics that may help differentiate between opacification of a developmentally asymmetric lateral recess and a true expansile lesion of the sphenoid sinus. METHODS Coronal CT was performed in ...

Introduction: First branchial cleft anomalies manifest with duplication of the external auditory canal.   Case Report: This report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. External auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and...

by determining normal ranges of spinal canal diameters we can make early diagnosis in persons who have lower diameters of spinal canal. these persons are predisposed to spinal canal stenosis that is a major cause of spinal radiculopathies. in different studies performed in several countries, minimum and maximum ranges of spinal canal diameters were different for each population. in this study, ...

Context Root canal anatomy is evaluated using different methodologies. Aims The aim of this study is to evaluate and classify root canal morphology and dentin thicknesses (DT), comparing radiographic and micro-computed tomography (CT) analysis. Materials and Methods Canal diameter and DT of mandibular incisors (n = 520) were evaluated using digital radiographs in buccolingual (BL) and mesio...

Introduction. The aim of this work was to check the average thickness dentinal wall mesio-buccal root first lower molar using CBCT axial sections intact teeth. Material and method. In cross-sectional study, 100 images mandibular molars from Promax 3Dent radiology center in Banja Luka, Bosnia Herzegovina were evaluated. A Planmeca Promax3D Max apparatus (Planmeca, Helsinki, Finland) used, with a...

Scleral thickness, especially near the optic nerve head (ONH), is a potential factor of interest in the development of glaucomatous optic neuropathy. Large differences in the dimensions of the sclera, the principal load-bearing tissue of the eye, have been observed between individuals. This study aimed to characterize the effects of these differences on ONH biomechanics. Eleven enucleated human...

AIM To compare the average sealer cement film thickness and the extent and pattern of sealer penetration into dentinal tubules in association with four obturation techniques in curved root canals. METHODOLOGY Mesial canals of 44 extracted mandibular molars were randomly divided among the SimpliFill, continuous wave, Thermafil and 0.04 matched taper (master cones) lateral compaction obturation...

BACKGROUND Mandibular Sagittal Split Osteotomy (MSSO) is a popular technique in orthognathic surgery used both to advance and to retreat the mandible. However, MSSO may incur in important complications, such as bad splits and sensorineural injuries. Knowing the location of the fusion between the buccal and lingual cortical (FBLC) in the mandibular ramus and the bone thickness in the region wher...

The consequences of traumatic injuries are pulp necrosis, periapical inflammation, and possible external cervical resorption (ECR). concomitant cessation root maturation dentinogenesis in premature teeth result a fragile tooth. Revascularization the might be an alternative treatment option. A 12-year-old patient was referred for retreatment chronic apical periodontitis with acute exacerbation a...
