1/6. Restoration of a dentition affected by dentinogenesis imperfecta using In-Ceram: a case report.A patient suffering from dentinogenesis imperfecta and consequent noncarious tooth destruction was rehabilitated using In-Ceram crowns. The problems encountered in the diagnosis, treatment planning and treatment are discussed.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
2/6. dentinogenesis imperfecta associated with short stature, hearing loss and mental retardation: a new syndrome with autosomal recessive inheritance?The follow-up history and oral findings in two brothers from consanguineous parents suggest that the association of dentinogenesis imperfecta (DI), delayed tooth eruption, mild mental retardation, proportionate short stature, sensorineural hearing loss and dysmorphic facies may represent a new syndrome with autosomal recessive inheritance. Histological examination of the dentin matrix of a permanent molar from one of the siblings reveals morphological similarities with defective dentinogenesis as presenting in patients affected with osteogenesis imperfecta (OI), a condition caused by deficiency of type I collagen. A number of radiographic and histological characteristics, however, are inconsistent with classical features of DI. These findings suggest that DI may imply greater genetical heterogeneity than currently assumed.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
3/6. dentinogenesis imperfecta in the Brandywine isolate (DI type III): clinical, radiologic, and scanning electron microscopic studies of the dentition.Teeth of seven patients from the Brandywine isolate who had dentinogenesis imperfecta (DI) type III were evaluated by clinical, radiologic, and scanning electron microscopic techniques. The deciduous and permanent teeth were opalescent, and there was marked attrition. Enamel pitting was present on some permanent teeth. Anterior open bites were found in all persons with complete permanent dentitions. Pulps of developing teeth were larger than normal during early development but rapidly became almost completely obliterated. There was increased constriction at the cementoenamel junctions. While radiolucencies were noted at the apices of teeth which had pulp exposures due to attrition, several patients had similar radiolucencies which could not be attributed to caries or attrition. Scanning electron microscopy showed a significant reduction in the number of dentin tubules on fractured dentin surfaces; calcospherites at the calcification front were either irregularly shaped or absent. A single tooth from a patient with DI type II was studied and had similar abnormalities on scanning electron microscopy, although tubules were easier to find and calcospherites at the calcification front were more regular than in DI type III. The findings in DI type III of enamel pitting, enlarged pulps early in tooth development, and radiolucencies at the apices of teeth without pulp exposures support the hypothesis that DI type II and DI type III are different disorders.- - - - - - - - - - ranking = 2keywords = tooth (Clic here for more details about this article) |
4/6. Thirteen-year-old boy with dentinogenesis imperfecta - pedodontic and orthodontic treatment.dentinogenesis imperfecta is a hereditary condition characterized by disturbance in tooth formation. The colour of the teeth vary from opalescent greyish-blue to an amber-like colour on the teeth with splitting of the enamel. On the roentgenogram the marked obliteration of the pulp chambers is a characteristic feature. This case report describe a 13-year-old boy with dentinogenesis imperfecta. High caries activity resulted in extensive caries on the first permanent molars. The boy had to be treated orthodontically to create acceptable occlusion. The treatment was carried out with fixed appliance and started after extraction of the four first permanent molars. No observable injury was recorded during the treatment.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
5/6. Carbamide peroxide bleaching of teeth with dentinogenesis imperfecta discoloration: report of a case.Carbamide peroxide dental bleaching has gained much popularity in the past 5 years. Because tooth discoloration caused by dentinogenesis imperfecta involves deep, dark, dentinal stain, practitioners might believe that affected teeth would be resistant to color improvement by bleaching. This article reports the successful use of carbamide peroxide at-home bleaching in a teenager with dentinogenesis imperfecta. Six-month treatment results are shown.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
6/6. dentinogenesis imperfecta: influence of an overdenture on gingival tissues and tooth mobility.Case report of a child demonstrating severely-worn primary dentition with dentinogenesis imperfecta is presented. Overdentures were fabricated in order to preserve clinical crowns, re-establish the clinical dimension of occlusion and provide esthetics. The patient underwent monthly recall visits for a 6-month period, during which most rapid changes concerning the gingival tissues and tooth mobility were expected.- - - - - - - - - - ranking = 5keywords = tooth (Clic here for more details about this article) |
