Summary Epidemiology The prevalence is unknown.

Comparing clinical signs, symptoms and CBCT image, the hypothesis of dental ankylosis was suggested, because infraocclusion of tooth 16 was below the contact area of the teeth 17 and 15 Fig.

The patient did not report pain and remembered the trauma that occurred in the region, when he was a child during a football game. The ethics committee on human research exempted this study approval since only CBCT images would be disclosed without the possibility of patient identification.

Permanent molars are less frequently affected than deciduous molars. The material is in no way intended to replace professional medical care by a qualified specialist and should not be used as a basis for diagnosis or treatment.

Orphanet: Anquilosis dental

Dental ankylosis diagnosed by CT with tridimensional reconstructions. The present study contains a case report of a male patient with ankylosis in tooth 16 diagnosed by CBCT, aiming at providing information for dentists about this anomaly, its characteristics and situations in which CBCT should be indicated. With equal accuracy, cone beam computed tomography CBCT can also be used for the diagnosis of ankylosed teeth Balaji, ; Hashim et al. In the present case, as in the primary eruption failure, a posterior tooth was affected.

Conebeam computed tomography in orthodontics: When infraocclusion is less than 5 mm, it is possible to carry out restorative treatment with the use of restorative materials or prosthetic crowns for reestablishing dental occlusion Lim et al. With the lack of accessibility of anquikosis tests in dental offices to confirm the occurrence of primary failure Rhoads et al.

However, ankylosis early diagnosis is difficult, for in the beginning areas absence periodontal ligament are small and the tooth still presents mobility Cohen-Levy et anqjilosis. Diagnostic methods Clinical examination and X-ray are the main diagnostic methods for detecting ankylosis.

Thus, once the crown of the tooth dentsl below the point of contact of teeth 17 and 15, it was suggested that the ankylosis occurred early in the phase of the eruption process during the patient’s childhood.

Whereas cone beam computed tomography CBCT allows a three-dimensional assessment of axial, coronal, and sagittal planes of all dental extension, eliminating thus overlapping images and helping anquikosis confirm the correct diagnosis. Also, it is not possible to visualize the root bifurcation area Silva.

Diagnosis and treatment of severe dentoalveolar ankylosisin primary molars: However, for identifying the root region extent and exact location where ankylosis is present, the examination by three-dimensional imaging is essential Paris et al.

In order to be acknowledged with the subject, we made a research in the PubMed database, using the following key words: Whereas computed tomography CT is considered superior to radiography Kirziolu et al.

Anquilosis del Primer Molar Permanente: Primary failure of eruption: The major characteristic of a secondarily retained molar is infraocclusion that may result in malocclusion. Multiplanar reconstructions MPR were obtained and in the panoramic reconstruction, in sagittal and coronal planes, it was observed that in addition to unerupted teeth 18 and 28, the patient had tooth 16 partially erupted, with its roots in contact with the maxillary sinus and absence periodontal ligament space along the roots Figs.

Disease definition Dental ankylosis is a rare disorder characterized by the fusion of the tooth to the bone, preventing both eruption and orthodontic movement. The disorder may result in loss of the retained molar and neighboring teeth due to caries and periodontal disease, and in deformation of the facial skeleton reduction dentla the height of the lower face, relative mandibular prognathism, posterior open bite.

Therefore, depending on anquilosks level of infraocclusion, abquilosis may trigger several clinical implications during jaws development and growth, e. A case report of a discordant twin pair.

As observed in the case reported, the more evident clinical sign of ankylosis is the presence of infraocclusion Cohen-Levy et al. Value of computed tomography CT in imaging the morbidity of submerged molars: Radiographic testing enables assessing only proximal regions of possibly affected roots. However, unlike the primary failure, normal eruption of adjacent teeth was observed.

Although periapical x-rays are daily used in dental clinics, their value is limited for diagnosisof ankylosed teeth Paris et al. Late diagnosis of dentoalveolar ankylosis: Clinical description The periodontal ligament is obliterated by a ‘bony bridge’ and the tooth root is fused to the alveolar bone.

Diagnosis by Cone Beam Computed Tomography. However, since only one third of the patients present these clinical signs Cohen-Levy et al.
