BACKGROUND AND PURPOSE Numerous follow-up visits for wrist fractures in children are performed without therapeutic consequences. We investigated the degree to which the follow-up visits reveal complications and lead to change in management. The stability of greenstick and buckle fractures of the distal radius was assessed by comparing the lateral angulation radiographically. PATIENTS AND METH...

OBJECTIVE To compare the mesiodistal root angulation of panoramic images generated from traditional panoramic tomography or cone-beam computed tomography (CBCT). METHODS CBCT scans and panoramic radiographs of 20 patients were collected. The Invivo- Dental 5.0 was separately applied for maxillary or mandibular panoramic image generation. The generation method was assorted by two head position...

The purpose of this study was to investigate the eruption speed and rate of angulation change of a cyst-associated mandibular second premolar after marsupialization of a dentigerous cyst in preadolescents. Premolars on the cyst and noncyst sides and size of the cyst were retrospectively examined with a total of 42 pairs of normalized panoramic radiographs in 20 patients who underwent neither ex...

BACKGROUND The aim of this study was to investigate clinical outcomes of fifth metacarpal neck fractures using antegrade single elastic nail and to explore ideal puncture point to avoid iatrogenic ulnar nerve injury. METHODS A single elastic nail with suitable diameter was used in 27 cases of fifth metacarpal neck fractures with dorsal angulation over 45°. An initial entry point was perforate...

BACKGROUND This paper deals with the fabrication of a three-dimensional stent which is simple in design but provides an accurate placement of a mini-implant in three planes of space, namely, sagittal (root proximity), vertical (attached gingiva/alveolar mucosa) and transverse (angulation). FINDINGS The stent is made of 0.018×0.025 in. stainless steel archwire which consists of a 'u loop' angu...

OBJECTIVE The aim of this study was to evaluate the effects of upper incisors and canine angulations introduced by different bracket prescriptions on dental arch perimeter. MATERIALS AND METHODS Cone beam computerized tomography scans collected using I-Cat (Imaging Sciences International, Hatfield, PA, USA) were selected conveniently from a database of routine exams of a clinical radiology ce...

OBJECTIVE Decompressive laminectomy is one of the most commonly used surgical methods for the treatment of spinal stenosis. We retrospectively examined the risk factors that induce spinal instability, including slippage (spondylolisthesis) and/or segmental angulation after decompressive laminectomy on the lumbar spine. METHODS From January 1, 2006 to June 30, 2010, 94 consecutive patients und...

Regarding the mathematical study of Inoue et al. 1, it is appropriate to mention the study by Cheng (Apud Collins) 2 published more than half a century ago in which the width of the circular epidural space (EP) and thickness of the dura mater (DM) were measured. According to Cheng 2, the axial width of EP at L2-L3 is 6 mm and if the puncture is 30 degrees to the skin, the puncture safety margin...

BACKGROUND The analysis of nasal anatomy, and especially the nasal bones including the osseocartilaginous vault, is significant for functional and aesthetic reasons. OBJECTIVES The objective was to understand the anatomy of the nasal bones by establishing new descriptions, terms, and definitions because the existing parameters were insufficient. Adequate terminology was employed to harmonize ...
