BACKGROUND Many reports have indicated the treatment for permanent teeth with disturbed eruption due to the presence of supernumerary teeth. However, successful treatment for an unerupted maxillary incisor with severe rotation and another maxillary incisor with disturbed eruption by a supernumerary tooth is quite rare. CASE REPORT We treated a 7-year-old Japanese male with an unerupted and se...

the success of endodontic therapy requires knowledge of the internal and external dental anatomy and its variations in presentation. this case report involves endodontic treatment of a traumatized maxillary central incisor with two separate roots.

introdouction: dentigerous cyst is a benign developmental lesion of the jaw. it is most commonly occurs during the second and third decades of life and has rarely been reported in association with a deciduous tooth. we report a case of two-year old girl who presented with an unerupted central incisor. according to the radiographic findings, she was diagnosed with a dentigerous cyst and underwen...

a case with two simultaneous dens invaginations (dis) and one dens evagination (de) in a permanent maxillary lateral incisor is reported for the first time in a 21-year-old girl. de known as talon cusp of the anterior teeth is a rare entity and its co-existence with di has been reported scarcely in the literature. simultaneous occurrence of two dis with one de has not been reported elsewhere. u...

Immediate implant placement is most commonly indicated when tooth extraction performed owing to pathologies such as unrestorable caries or fractures. The primary advantage of this treatment modality the diminution healing time and reduced alveolar process resorption. Regenerative materials can be used an adjunct with implants in order triumph high survival rate enrich good esthetic outcome. Thi...

Cone-beam computed tomography (CBCT) provides images without overlapping anatomical structures, which is important for the diagnosis and assessment of florid cemento-osseous dysplasia. This fibro-osseous lesion that affects alveolar process compromising teeth’ pulp vitality usually asymptomatic, bone expansion, cortical disruption, root resorption are uncommon. Due to its avascular characterist...

The epithelial tissue forming the posterior aspect of the apical foramen in the upper incisor of the rat was reconstructed from 1 μm thick serial cross sections. Like the lower incisor, this portion of the odontogenic organ in the upper incisor was composed of a bulbous and a "U"-shaped part. However, the bulbous part was considerably blunter and the "U"-shaped part much larger in circumference...

Abstract Impaction of maxillary central incisors is not common. Treatment of an impacted central incisor is challenging as it relates to facial esthetics and dental function. Although impaction of permanent teeth is rarely diagnosed in mixed dentition period, an impacted central incisor is usually diagnosed when there is a delay in the eruption of tooth. Tooth impaction may result from...

a case of a compound odontoma which caused delayed eruption of right maxillary central incisor in a ten year old girl is presented with clinical and radiographic findings. the patient presented with complaint of a hard painless swelling in the right anterior region of the maxilla and absence of right maxillary central incisor. after clinical examination, periapical and occlusal radiographs of t...
