The aim of this work was to identify the limitations of previously published systematic reviews evaluating the outcome of root canal treatment. Traditionally, periapical radiography has been used to assess the outcome of root canal treatment with the absence of a periapical radiolucency being considered a confirmation of a healthy periapex. However, a high percentage of cases confirmed as healt...

PURPOUSE The Authors correlated intraoperative mucohaemorrhoidal prolapse morphology, specimen histology, anal canal length and purse-string height. METHODS Between September-November 2010, 18 patients (9 grade III; 9 grade IV haemorrhoids) underwent stapled haemorrhoidopexy. Mean age was 54 years (range 38-78).Proctoscopic prolapse morphology, anal canal length, pursestring height and extern...

AIMS To characterise lamina cribrosa and anterior scleral canal wall architecture in pressurised (IOP 10 mm Hg) and non-pressurised (IOP 0 mm Hg) normal monkey eyes. METHODS Eight normal eyes from eight monkeys were enucleated before sacrifice and the optic nerve heads (ONH) trephined and immersion fixed in glutaraldehyde (IOP 0). Nine normal eyes from nine monkeys were perfusion fixed in sit...

OBJECTIVE To assess the impact of obesity on carotid intima media thickness and left ventricular (LV) mass in obese adolescents. METHODS The study included 52 obese adolescents (mean age 14.16+/-2.64 years) and 52 healthy adolescents who served as a control group (mean age 12+/-2.3 years), who were attended the outpatient clinic at Suez Canal University Hospital, Ismailia, Egypt. The study po...

The aim of this study was to compare three different cone-beam CT (CBCT) instruments used in dental clinical practice with micro-CT as gold standard. Three female monkeys' (Macaca fascicularis) skulls were selected and scanned by the tested CBCT-s. The most apical visible root canal level on the CBCT images was used as reference level (RL). After the image acquisition by CBCT-s dental jaw secti...

The present study was carried out to observe root canal variations in maxillary and mandibular first premolar teeth in the local population using spiral computed tomography. Sixty, each of well formed maxillary and mandibular first premolar teeth without any carious lesions were used in this study. They were placed in 5% sodium hypochlorite solution for 30 minutes for the removal of organic deb...

This study describes the treatment of a necrotic immature permanent central incisor with crown fracture. Instead of the conventional root canal treatment, a regenerative approach based on conservative endodontic method for revascularization was provided. The root canal was gently debrided of necrotic tissue by irrigating with sodium hypochlorite and then medicated with tri-antibiotic paste. Aft...

We describe a systematic approach to the ultrasound (US) examination of the antropyloric region in children. US is the modality of choice for the diagnosis of hypertrophic pyloric stenosis (HPS). The imaging features of the normal pylorus and the diagnostic findings in HPS are reviewed and illustrated in this pictorial essay. Common difficulties in performing the examination and tips to help ov...

Background. A theoretical model analysis of stress in the vestibular membranes has identified a geometrical stress factor incorporating shape, size, and thickness that can be used to assess peak stress in the various chambers. Methods. Using published measurements of the toadfish vestibular membranes made during surgery, the geometrical stress factor can be evaluated for each chamber based on t...

A microcomputer based video image analyzer is described and demonstrated in the analysis and comparison of tissue types of 6-month-old Ethrel-treated and control seedlings of loblolly pine (Pinus taeda L.). Two different programs were employed. ;Topographer I' sought, identified, and measured cell or resin canal lumen areas, and ;Area' measured tracheid length and silhouette areas. Ethrel treat...
