Gastrointestinal foreign bodies (FB) are comprised of food bolus impaction and intentionally or unintentionally ingested or inserted true FB. Food bolus impaction and true FB ingestion represent a recurrent problem and a true challenge in gastrointestinal endoscopy. More than 80-90% of the ingested true FB will pass spontaneously through the gastrointestinal tract without complications. However...

In order to investigate the osteoinductive properties of allograft used in impaction grafting and the effect of strain during impaction on these properties, we designed an in vitro experiment to measure strain-related release of bone morphogenetic protein-7 (BMP-7) from fresh-frozen femoral head allograft. A total of 40 10 mm cubes of cancellous bone were cut from ten samples of fresh-frozen fe...

PURPOSE The classification of impacted maxillary third molars (IMTMs) facilitates interdisciplinary communication and helps estimate the degree of surgical difficulty. Thus, this study aimed to develop a 3-dimensional classification of the position and depth of impaction of IMTMs and to estimate their prevalence with respect to gender and age. MATERIALS AND METHODS This cross-sectional retros...

BACKGROUND AND AIMS In hemostasis for colonic diverticular bleeding, the incidence of recurrent bleeding is higher in deep colonic diverticulum than in shallow. We aimed to improve and evaluate barium impaction therapy using an enteroscopic overtube with balloon. PATIENTS AND METHOD We performed barium impaction therapy in three patients with a diagnosis of deep colonic diverticular bleeding....

BACKGROUND A combination of horizontal and vertical third molar impaction is a rare occurrence.When the tooth is unable to erupt to its proper position and fail to achieve a normal occlusion, it is known as impacted tooth. CASE DETAILS In this scientific article, case report of a female patient aged 30 years reported with acombination of horizontally and vertically impacted third molars in th...

Tooth impaction is a pathological situation where a tooth fails to attain its normal functional position. Impacted third molars are commonly encountered in routine dental practice. The impaction rate is higher for third molars when compared with other teeth. The mandibular third molar impaction is said to be due to the inadequate space between the distal of the second mandibular molar and the a...

AIM The purpose of this paper was to describe the dental and surgical management of the impaction of deciduous maxillary anterior teeth due to compound odontoma. In all analysed patients impaction of the maxillary deciduous canine was associated with the presence of an odontoma. Therefore, impaction of the maxillary deciduous canine can be considered as pathognomonic of the presence of an in...

Vertical transport of many atmospheric trace gases is modulated by retention in solid (ice phase) precipitation during the impaction and freezing (i.e., timing) of supercooled cloud droplets. Here we report field measurements of the concentrations of both hydrogen peroxide (H202) and molecular oxygen (02) in time ice. Gas retention efficiencies, defined as the ratio of the observed concentratio...
