corono-radicular biological restoration of maxillary central incisors by direct method

Fracture resistance of endodontically treated teeth with different direct corono-radicular restoration methods

BACKGROUND Endodontically treated teeth are widely considered to be more susceptible to fracture than vital teeth. Obturation procedures and post placement have been a main cause of vertical root fracture. MATERIAL AND METHODS Forty-eight human premolars with standardized weakened roots were endodontically treated and allocated to four experimental groups (n=12). After root canal treatment, i...

Double maxillary central incisors: a case report

Double maxillary central incisors: a case report Dr. J. Ghoddusi* - Dr. A. Rohani** *- Associate Professor of Endodontics Dept. Faculty of Dentistry & Dental Research Center - Mashhad University of Medical Sciences. ** - Endodontist.Introduction: Fusion and Gemination are developmental anomalies of the dental hard tissue. The preferred terminology for these two abnormalities is "double teeth". ...

Emergence times of maxillary central incisors and mandibular lateral incisors were less variable than those of maxillary lateral incisors and mandibular central incisors. Maxillary lateral incisors

Understanding of tooth eruption in humans remains incomplete. We hypothesized that genetic factors contribute significantly to phenotypic variation in emergence of primary incisors. Modelfitting was applied to data from Australian twins to quantify contributions of genetic and environmental factors to variation in timing of emergence of human primary incisors. There were no significant differen...

Restoration of fractured immature maxillary central incisors using the crown fragments.

Corono Radicular Anomaly in a Maxillary First Molar – a Rare Case Report

Developmental dental anomalies refer to deviation from the normal size, shape, number or structure of external and internal anatomy of a tooth. Their presence have functional and clinical significance. With no definite reason some dental anomalies may occur commonly in some specific teeth like microdontia in maxillary lateral incisors, dens invaginatus in maxillary lateral incisors, dens evagin...

Esthetic Restoration of Two Severely Decayed Maxillary Central Incisors: A Case Report

coronal tooth tissue can use a post to retain a core enabling definitive restoration. Post material has been, until recently, primarily metal--be it cast or prefabricated. Currently, fiber-posts are promoted as being advantageous due to a favorable failure mechanism which may protect the root from fracture [1]. Endodontic posts are necessary to provide adequate retention and support when no suf...
