Functional, esthetic and biologic restoration of a fractured incisor often presents a daunting clinical challenge. The outcome of conventional composites, prosthodontic restorations in a young patients result in an uncertain longevity of the same. Reattachment of the fractured fragment of a tooth helps in maintaining both morphology and esthetics in a growing child until the permanent long last...

BACKGROUND Pars plana vitrectomy (PPV) is preferred surgical procedure for the management of complex rhegmatogenous retinal detachment (RRD). The purpose of this study was to evaluate the anatomical results of primary PPV for the treatment of primary complex RRD and to determine the influence of lens status, tamponading agent, preoperative proliferative vitreoretinopathy (PVR) and axial length ...

This retrospective observational case series on eyes from three patients was done to elucidate the developmental mechanism of spontaneous reattachment of rhegmatogenous retinal detachment (SRRRD). The study eyes of each patients showed evidence of retinal break and diffuse retinal pigmentary change. Ultrasound biomicroscopic examination revealed vitreous fibers attached to the area around the r...

AIMS The long-term results of office-based pneumatic retinopexy (PR) using only filtered air were evaluated in a case series of rhegmatogenous retinal detachments with more than 3 years of follow-up, on average. METHODS 77 cases of primary rhegmatogenous retinal detachments arising from superior tears (mean=1.6 tears) were treated with cryopexy (n=61) or laser (next day, n=16) and intravitrea...

The presence of circulating tumor cells (CTCs) in blood predicts poor patient outcome and CTC frequency is correlated with higher risk of metastasis. Recently discovered, novel microtubule-based structures, microtentacles, can enhance reattachment of CTCs to the vasculature. Microtentacles are highly dynamic membrane protrusions formed in detached cells and occur when physical forces generated ...

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...

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...
