A displasia dentinária é uma alteração do desenvolvimento da dentina rara, de origem autossômica dominante, o qual é geralmente dividida em 2 tipos. A displasia fibrosa é lesão pseudo-neoplásica de etiologia desconhecida, da pirâmide nasal à esquerda, deslocamento da arcada dentária superior para a.

This transitional stage of root formation ends with the full development of the root when it reaches occlusal contact. In the WHO classification defined specific types of cystic lesions and solid tumor mass as well as their development. Dental lesions in tumoral calcinosis.

DISPLASIA DENTÁRIA by Weslley Pereira on Prezi

Anterior teeth appeared to be less affected than posterior, and tooth loss was less prevalent, suggesting thereby that this type of dentin dysplasia can be divided into 2 subgroups, as proposed by Scola and Watts The upper right canine erupted in an infralabial inclined position, while the upper left canine was partially erupted due to space deficiency. J Am Dent Assoc ; The second deciduous left lower molar 75 was still in place Fig. The authors declare that procedures conformed to the ethical standards of the responsible committee on human experimentation and in accordance with the World Medical Association and the Declaration of Helsinki.

Affected teeth usually appear as brownish-blue, brown or yellow. This page visplasia last edited on 24 Novemberat Ossifying fibroma involving the paranasal sinuses, orbit, and anterior cranial fossa: Among these 41 cases, gender and location data were specified in only 27 cases: A new panoramic radiograph taken 1 year later revealed arrest of root formation in teeth 34, 35 and 37 Fig.

At first, orthodontic movement is only contraindicated for teeth with SRA in extreme cases. It is difficult to perform an endodontic therapy on teeth that develop abscesses as a resultant of obliteration of the pulp chambers and root canals.

However, reports of cases without signs of a family heritage are found in the literature 6,16 in the same way as described for our patient.

Services on Demand Journal. More tooth loss is likely to occur if intervention takes place. Services on Demand Journal.


Studies on the consecutive surgery of succedaneous and permanent dentition in the Japanese children. Although numerous theories have been proposed, the etiology of dentin dysplasia remains unknown.

Dentin dysplasia

World Health Organization; A mixed radiolucent-radiopaque well-defined unilocular lesion was found on an orthopantomographic examination, affecting roots Fig.

The progression of the case is under continuing evaluation. The final extraoral radiographs and cephalometric superimposition are shown in Figures 21 and Both onlay bone grafting and sinus lift techniques can be carried out together to accomplish implant placement. A differential diagnosis of SRA should be conducted for teeth with incomplete root formation, external apical root resorption, dentin dysplasia type I displasai post dental trauma root hypoplasia.

DGCT was then defined as a locally invasive neoplasm characterized microscopically by ameloblastoma-like odontogenic epithelial proliferation, an aberrant keratinization in the form of ghost cells and dysplastic dentin.

As for the dental pattern, it presented Class I relationship of right molars. We hope that additional studies in future will contribute to determining the best treatment options for DGCT in this line, as well as a better explanation of the precise histophatological, biological and clinical development of DGCT and to definitively determine whether aggressive resection is the best treatment for DGCT.

The treatment of dentinogenic ghost cell tumour. Dentin dysplasia is a rare defect of dentin development with an autosomal dominant pattern of inheritance, which is generally divided into 2 main classes based on the clinical and radiographic denginaria of the affected dental tissues: After two years there is no evidence of re-sprouting.

Differential diagnosis and an understanding of the etiological reasons for teeth with short roots enable orthodontic movement which requires biomechanical adaptations, periodic radiographic monitoring, clinical monitoring of tooth mobility and permanent retention, especially for the incisors.

Clinical examination disclosed grade III mobility of teeth [] with rhizolysis of teeth dentinaeia, 31 and 32, and painless swelling from displasiw right lateral incisive of the jaw to the left second molar area of dentijaria jaw.

Thinned cortical expansive lesion was observed on the lingual edge, and no septums were found Fig. Isolated cases of unknown origin have been reported, and have dissplasia categorized as idiopathic. Short-root anomaly in an orthodontic patient. An alternative to conventional dentinarka would be retrograde filling and periapical curettage. DD1 is characterized clinically by nearly normal appearing crowns and hypermobility of the teeth 11, Radiographic examination is an important diagnostic tool for identifying this dental anomaly 12revealing short, blunt and malformed roots, similar to those observed in taurodontic teeth, obliteration of all pulp chambers with crescent-shaped pulp remnants parallel to the cementoenamel junction and several periapical radiolucencies in noncarious teeth 1,2,5,7,8, This paper reports the case of a child with dental alterations suggestive of DD1, in whom only few permanent mandibular teeth were affected and different features from dentniaria found in the literature were observed.


The best method of maintaining the health of teeth is to practice exemplary oral hygiene. Dentures or over dentures can be considered, as rehabilitation until growth is completed.

Orthodontic movement of teeth with short root anomaly: should it be avoided, faced or ignored?

Clinically, moderate to severe mobility was observed in teeth 34 and 35, and areas of enamel hypomineralization were found in teeth 31, 32, 33, 42 and Calcifying odontogenic cyst COC was first described as a distinct pathology by Gorlin et al. Unsourced material may be challenged and removed. Taurodontism in 47 XXY males: Dilaceration Regional odontodysplasia Turner’s hypoplasia Enamel hypoplasia Ectopic enamel.

How to cite this article. The presentation of case reports in which classic signs of DD1 are found, but other typical features are not present highlights the clinical and radiographic variations of DD1.

In other projects Wikimedia Commons. The intraoral clinical examination revealed the presence of the following teeth: Scola and Watts 13 proposed a subclassification of DD1 as: However, evidence suggests that SRA has strong genetic origins, shown by striking family history.
