OBJECTIVE Late aortic root dilatation is a growing concern in patients operated on for tetralogy of Fallot (ToF). This longitudinal follow-up study sought to evaluate the changes in the aortic root dimensions in relation to body growth, assuming that early repair of tetralogy of Fallot might prevent late aortic dilatation. METHODS A retrospective analysis of the aortic root dimensions was per...

Progressive aortic root dilatation is a common feature after surgical repair of tetralogy of Fallot. This report describes a successful valve-sparing replacement of the aortic root in a patient with significant dilated aortic root and aortic regurgitation after repair of tetralogy of Fallot.

abstract introduction: in root canal therapy some accidents may happen that affects the prognosis of the tooth. for example, when preparing access cavity, perforation of furca is a possibility that leads to tooth loss. important factors in prognosis of furcation perforation include: the kind of materials used, area that perforation has happened in, time in which perforation is sealed and skill ...

Root perforations are an undesired complication of endodontic treatment which result in loss of integrity of the root, and adversely affect the prognosis of the treatment. Recently, Iranian mineral trioxide aggregate [Root MTA] has been introduced as an ideal material for perforation repair. In this article a successful repair of strip root perforation of mandibular molar using Root MTA is pres...

The purpose of the study was to investigate the relationship between root resorption and repair in human premolars that had been orthodontically intruded. The objective was to examine these processes related to time and root development. Seventy-six premolars were divided into subgroups: 33 teeth were intruded and then extracted (G1); 25 teeth were intruded and then left in situ for varying per...

A root perforation is a mechanical or pathological communication formed between the supporting periodontal apparatus of the tooth and the root canal system. Three broad categories of etiological factors exist and these are procedural mishaps, resorption and caries. The diagnosis, management and repair of root perforations require skill and creative thinking. Unfortunately, much of what has been...

In recent years, there has been significant progress in developing tools for debugging and repairing Description Logic (DL)-based ontologies with erroneous consequences. However, these tools place more emphasis on explaining why the consequences follow from the ontology rather than on eliminating them. Another shortcoming in existing tools is that there is no common approach for eliminating or ...

Meniscal repair indications have not really changed in recent years. Typically younger, more active patients with concomitant ACL reconstruction and peripheral third vertical tears continue to be the “best” repair candidates. However, even in these “ideal” candidates, meniscal repair continues to represent a significant challenge. While most will not dispute that vertical tears greater than 1 c...
