1/154. Combined surgical and orthodontic management of the oral abnormalities in children with cleidocranial dysplasia.

    Children with cleidocranial dysplasia have dental abnormalities which combine to prevent normal tooth eruption, and which if untreated may result in abnormal facial and jaw growth. A technique combining orthodontics and oral surgery has resulted in the establishment of excellent occlusion and facial appearance in these patients. Recent advances in direct enamel bonding techniques for orthondontic attachments have permitted a conservative surgical approach with minimal bone removal during surgery to expose unerupted teeth prior to orthodontic treatment.

2/154. Inverted impaction of a mesiodens: a case report.

    Dental, radiological, dermatoglyphic and genetic findings of a patient showing inverted impaction of a mesiodens are presented. It is probable that the inversion of the mesiodens was caused by contact of the incisal edge of the crown of the mesiodens by the apex of the root of the erupting right maxillary central incisor tooth.

3/154. Unerupted second primary mandibular molar positioned inferior to the second premolar: case report.

    This report is a clinical case of a 7-year-old child who presented right impacted second primary mandibular molar. This tooth was positioned inferior to the second premolar successor and a supernumerary tooth superior to the second premolar. Clinical examination did not reveal systemic diseases ot trauma in the facial region. Treatment consisted of the extraction of the impacted second primary molar and the supernumerary tooth. Periodic examination was indicated for follow-up.

4/154. Radiographic localization of unerupted maxillary anterior teeth using the vertical tube shift technique: the history and application of the method with some case reports.

    The preferred means of radiographic localization is the parallax method introduced by Clark in 1910. He used 2 periapical radiographs and shifted the tube in the horizontal plane. In 1952, Richards appreciated that a vertical tube shift could also be carried out. No major changes then occurred in the technique until Keur, in australia, in 1986 replaced the periapical radiographs with occlusal radiographs. This modification enables a greater tube movement and therefore a greater shift of the image of the impacted tooth; it also ensures that the whole of the tooth is captured on the radiograph. For the vertical tube shift, Keur introduced the use of a rotational panoramic radiograph with an occlusal radiograph. In 1987, Southall and Gravely discussed this vertical tube shift combination in the English dental literature, and it is now the preferred combination of radiographs for localizing impacted maxillary anterior teeth. Jacobs introduced this method to the American literature in 1999, but it has yet to gain acceptance in the continental European literature. Jacobs recommended, when using this combination, to routinely increase the vertical angulation for the occlusal radiograph by 10 degrees to achieve a greater image shift. Four case reports are presented in this article. Three have photographs taken at surgical exposure to illustrate how the position of the impacted tooth can be accurately predicted by appropriate interpretation of the radiographs.

5/154. Orthodontic, genetic, and periodontal considerations in the treatment of impacted maxillary central incisors: A study of twins.

    Treatment of twins each with one impacted maxillary central incisor and a mesiodens is described. Treatment included rapid expansion, extraction of the mesiodens, surgical exposure of the impacted central incisor, and its forced eruption. The impacted incisor was brought into functional position in one patient but was lost in the other because of insufficient root length and high mobility. Orthodontic, genetic, and periodontal considerations of these 2 cases are evaluated.

6/154. Mesiodens in the primary dentition--a case report.

    Supernumerary teeth are among the most significant dental anomalies affecting the primary and the permanent dentitions. Mesiodens is a supernumerary tooth with a cone shaped crown and a short root. Though it occurs frequently in the permanent dentition, it is extremely rare in the primary dentition. The exact etiology is still obscure and not well understood. Supernumerary teeth occur as isolated dental findings or as part of a syndrome. The frequency with which supernumerary teeth occur and the effects they have on development of normal occlusion justify the radiographic examination of preschool children. Early removal of such teeth is recommended if they impede the eruption of adjacent permanent teeth, appear inverted or rudimentary, associated with certain pathologic conditions or are symptomatic.

7/154. Misdiagnosis of an impacted supernumerary tooth from a panographic radiograph.

    A panographic radiograph of a 31-year-old man revealed the presence of an impacted supernumerary paramolar. Periapical radiographs of the same area failed to confirm the existence of this supernumerary tooth. A review of the inherent distortion factors present in panographic radiography leading to the misdiagnosis is discussed.

8/154. Orthodontic treatment of a patient with multiple supernumerary teeth and mental retardation.

    Supernumerary teeth may lead to impaction or ectopic eruption of maxillary incisors, crowding, oronasal fistula, follicular cyst, migration of adjacent teeth and root resorption. In this presentation, an 11-year-old male patient with 4 supernumerary teeth in the maxillary anterior region and a slight mental retardation problem will be presented. After extraction of the supernumerary teeth, the large space created by distal migration of central incisors was closed by orthodontic treatment. Although initial patient compliance was weak and caused difficulties in the course of treatment, orthodontic treatment was completed successfully.

9/154. Retention of permanent incisors by mesiodens: a family affair.

    The term mesiodens refers to a supernumerary tooth that is present in the midline of the maxilla between the two central incisors. One or two mesiodentes may be present. We present a rare case of two sisters, in both of whom a pair of mesiodentes caused the retention of permanent incisors. They were referred to our hospital with asymptomatic delayed eruption of upper incisors. This article is written to point out genetic factors as the possible origin of supernumerary teeth.

10/154. root resorption of first permanent molar by a supernumerary premolar.

    A case is presented of root resorption of the lower right first permanent molar caused by a supernumerary premolar tooth. The first permanent molar was subsequently extracted.
