“…A recent systematic review 7 reported that 16% of their included articles dealt with CBCT imaging in orthodontics, and they covered the use of miniscrews in assessing palatal bone thickness, 8,9 safe zones for placement in the maxillary and mandibular arches, 10 fabrication of surgical guides for their placement, 11 cephalometrics, [12][13][14] tooth position 15 and inclination, 16,17 assessment for rapid maxillary expansion, 18 determining skeletal age based on cervical vertebrae morphology, 19 and three-dimensional evaluation of upper-airway anatomy in adolescents. 20 Other orthodontic uses include planning surgical exposure of impacted canines 21 and orthognathic surgery in patients with facial asymmetry, 22 temporomandibular joint (TMJ) disorders, 23 and obtaining additional diagnostic information to assist in treatment planning. 24 Reports of incidental findings on CBCT are sparse.…”

Cone beam computed tomography (CBCT) of orthodontic patients is a diagnostic tool used increasingly in hospital and primary care settings. It offers a high-diagnostic yield, short scanning times, and a lower radiation dose than conventional computed tomography. This article reports on four incidental findings-that appear unrelated to the scan's original purpose-arising in patients for whom CBCT was carried out for orthodontic purposes. It underlines the need for complete reporting of the data set. (Angle Orthod. 2011;81:350-355.)

One or two mesiodens are mostly common to the clinician. However, three mesiodens is rarely found and can cause complications such as orthodontic problems or interruptions of the adjacent teeth with more than 1 or 2 mesiodens.Many factors cause irregularities in the permanent dentition. Mesiodens, especially in the anterior maxilla, can disturb the eruption of adjacent permanent teeth and cause diastemas, ectopic eruptions, root resorption, or the formation of dentigerous cysts. The early diagnosis of mesiodens is important for preventing such complications, and the timing of intervention should be based on their location and number. Periodic checkups and improved diagnostic devices make it easy to find mesiodens and associated complications.In this case, 3 supernumerary teeth in the maxillary anterior region were affecting the eruption of the adjacent permanent incisors. To minimize complications and preserve the deciduous teeth, the three supernumerary teeth were extracted in 2 steps.Since cone-beam computed tomography was not available, a brace wire was used to measure the depth of the mesiodens.

“…Current opinion does not ascribe a ny importance to the non-resorption of the deciduous canine as an aetiologic factor in PDC. 20 The findings of Schmuth et al 21 refute the influence of apparently unresorbed deciduous canines. In a computerized tomography (CT) study of 13 aberrant canines they found cases where the CT image revealed root resorption of the deciduous canines which was not apparent on conventional X-ray images of the same area.…”

Reducing the incidence of unerupted palatally displaced canines by extraction of deciduous canines. The history and application of this procedure with some case reports

The procedure of extracting the deciduous canine to reduce the incidence of the unerupted palatally displaced canine was first described in 1951, and an article solely devoted to the technique appeared in 1959. The procedure then virtually vanished until 1981. A prospective study published in 1988 created the first widespread interest in the method which now appears in major texts. Why the procedure succeeds is uncertain. In the 1950s nonresorption of the deciduous canine was thought to cause palatal deflection of its successor and therefore it appeared appropriate to extract the obstructing deciduous tooth. It has been estimated that the technique should be successful in approximately one in three of all cases in the population aged 10 to 13 years. The earlier the detection the better the prognosis, because the unerupted canine frequently moves more mesially with time. Before the procedure is attempted it is important to discuss possible outcomes with the patient. Three successfully treated cases are illustrated. The first conformed with the guidelines of having an uncrowded maxillary arch and being aged between 10 and 13 years. The second was aged 15 years 2 months at commencement. An unsuccessful surgical exposure of the permanent canines followed by extraction of the deciduous canines was carried out in the third case.
