Coronal fractures of permanent dentition are the most frequent type of dental injury. If the original tooth fragment is retained following fracture, the natural tooth structures can be reattached using adhesive protocols. The development and use of fiber-reinforced composite root canal posts make possible of the reattachment of the crown esthetically. This case report presents a clinical techni...

Recent reports" have shown that experi­ mental retinal detachment in the owl monkey (Aotes trivirgatus) produced photoreceptor outer-segment degeneration, and that surgi­ cal reattachment of the retina returned the outer segments to a normal configuration. The owl monkey is a nocturnal animal possessing a predominantly rod retina and an area centralis but no fovea. Because of the importance of ...

The backward-facing step flow (BFSF) is a classical problem in fluid mechanics, hydraulic engineering, and environmental hydraulics. nature of this flow, consisting separation reattachment, makes it worthy investigation. In study, divided into two parts, the effect cylinder placed downstream on 2D structure was investigated. Part 1, BFSF validated by using OpenFOAM. characteristics (reattachmen...

A numerical simulation of wavy core flow was carried out by Bai, Kelkar and Joseph. (1996). They calculated the interfacial wave shape for laminar flow. In our present simulation, the SST (shear stress transport) turbulence model is used to solve the turbulent kinetic energy and dissipation rate equations and a splitting method is used to solve Navier-Stokes equations for the wave shape, pressu...

Fracture of anterior teeth by trauma is a common problem in children and teenagers due to their active and carefree lifestyle. Reattachment of fractured fragment to the remaining tooth can provide good and long lasting aesthetics since the tooth original anatomic form, color and surface texture are maintained. It also restores function, provides a positive psychological response and is a relati...

PURPOSE To report 2 cases of delayed spontaneous Descemet membrane (DM) reattachment following big-bubble deep anterior lamellar keratoplasty (DALK). METHODS A 21-year-old man with keratoconus and a 36-year-old woman with corneal macular dystrophy underwent big-bubble DALK. No injury to DM was noted intraoperatively or postoperatively. Postoperatively, the patients developed central DM detach...

PURPOSE To document by optical coherence tomography (OCT) the reattachment of the margins of a retinal pigment epithelium (RPE) tear. METHODS Single case report, documented by OCT scans, autofluorescence and fluorescein angiography. RESULTS A 67-year-old male presented with a spontaneous RPE tear due to age-related macular degeneration in his right eye. Three months later we observed that t...

Injury of anterior teeth is a relatively common event that mainly affects children and adolescents. Dentists are confronted with managing dental trauma and restoring fractured teeth on a regular basis. Hence the techniques that speed and simplify the treatment, restore esthetics and improve long term success rate are considered of potential value. If an intact tooth fragment is present after tr...
