immature teeth have a large apical opening and thin divergent or parallel dentinal walls; hence, with conventional needle irrigation there is a very high possibility of extrusion. this study was done to compare the apical extrusion of naocl in an immature root delivered using endovac and needle irrigation.eighty freshly extracted maxillary central incisors were decoronated followed by access ca...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
introduction: open-apex teeth with irreversible pulpitis require complex and difficult treatment. providing the right environment for apexogenesis and pulp protection is vital for their long term prognosis. the young pulp of open apex tooth, however, is better equipped against irritation and assault. the aim of this study was to evaluate pulp inflammation in open apex canine teeth of cats. mate...
introduction: the ideal endodontic treatment for the teeth with in complete root-ends and necrotic pulps may involve the use of material which forms an immediate apical barrier instead of long term calcium hydroxide therapy. such procedure may lead us to a single appointment endodontic treatment. the purpose of the present study was to evaluate clinical and radiographic success rate in necrotic...
this case report describes treatment of a necrotic immature permanent mandibular first molar with pulpal necrosis in 9-year old female with spondyloepiphyseal dysplasia. the coronal half of the root canal was debrided with a file #30 to remove necrotic tissue, and irrigated with chlorhexidine 0.12%. bleeding was evoked to form an intracanal blood clot; the wound was then dressed with calcium hy...
this report describes a case of an eight years old girl who was treated for complicated crown fracture of right maxillary central incisor because of a sport accident. for the tooth total pulpotomy was performed in order to achieve apexogenesis and the tooth was restored with a composite resin. the patient was reviewed over 10 years. at first the tooth showed continued root development and compl...
Background and Objective: The endodontic management of immature teeth with wide open apices has always posed particular problems. A number of canal preparation and filling techniques have been described such as apexification, surgery and retrograde filling, customized-cone, and apical plug. The purpose of this study was to compare the sectional technique microleakage in open apices with ...

introduction: mineral trioxide aggregate (mta) mixed with normal saline has short working time, delayed setting time, and poor consistency when used as an apical plug. a preliminary study suggested that substituting normal saline with ky jelly or 5% calcium chloride (cacl 2 ) as a vehicle expedites the setting time of mta. the present in vitro study compared the microleakage of proroot mta mixe...
