[Dental abnormalities in cleidocranial dysplasia. Presentation of 4 cases].

Four patients, three in the same family, with cleidocranial dysplasia, are reported. The birth of a male newborn with cleidocranial dysplasia has allowed to investigate his mother and grandmother with the same condition. An other 30-year-old patient with cleidocranial dysplasia is described. All the adult patients showed the main clinical manifestations of the disease with the peculiar abnormalities of the dentition.

[Treatment of torsion abnormalities of central upper incisors caused by super-compact teeth].

A super-compact retained tooth is often responsible for rotation of a tooth round its axis; the retained tooth should be removed after preliminary x-ray examination of the site of abnormality. A great variety of etiopathological factors are responsible for the abnormality, and hence, the approaches to the choice of treatment are numerous. Rotation of teeth during orthodontic treatment involved stretching and strain of connective tissue fibers, which are not intended for rearrangement, and therefore the results are not stable. A long period of retention is needed for adaptation of tissues to a new position of the tooth.

[Prevalence of talon cusp in patients aged 7-18].

Talon cusp is an uncommon malformation. The aetiology is unknown although it is thought to be the combination of genetic and environmental factors. The purpose of the study was to examine the prevalence of talon cusps in children aged 7-18. 600 model casts were examined in the Pedodontic and Orthodontic Department of the Semmelweis University. Classification of talon cusps used was based on the degree of formation and extension by Hattab et al [6]. 12 talon cusps were found in the group of type 1, two were found in group of type 2 and one in type 3. The prevalence of talon cusps was 2.5%, mostly on the upper permanent lateral incisors. In four cases it was bilateral. The prevalence of talon cusps was more frequent in males compared to females. The early recognition of the anomaly is important from the therapeutic point of view (placement of sealant, periodic reduction of the cusp).

Orthodontic treatment of fused and geminated central incisors: a case report.

A 10-year old Egyptian male presented with a geminated upper right central incisor along with a fused and rotated upper left central incisor in cross bite. He also had severe crowding in the maxillary arch and a congenitally missing lower right first permanent premolar. Orthodontic treatment was carried out to align upper right and left central incisors, lateral incisors, and canines. Treatment options were discussed.

[An example of "leveling extraction" for repair of the 21st tooth supraposition].

A supercomplect retained tooth, situated under the 21st tooth, was removed in order to eliminate the supraposition (vestibular position) of the 21st tooth under conditions of lack of place in the dental arch. The 14th tooth on the contralateral side of the jaw was removed in order to maintain the symmetry and order of the anterior part of the maxillary dental arch and for creating place for the 21st tooth. Further transposition of the 13th tooth to the place previously occupied by 14th tooth, 11th tooth instead of 12th tooth, and establishment of the 21st tooth into correct position in the dental arch were carried out using orthodontic devices.

Oral manifestations in Ellis-van Creveld syndrome: report of five cases.

Ellis-van Creveld syndrome, or chondroectodermal dysplasia, is an autosomal recessive disorder with characteristic clinical manifestations. Its incidence in the general population is low. The oral manifestations of Ellis-van Creveld are found in soft tissues and teeth, but the dental literature on the subject is scarce. In the last 20 years, 5 cases of Ellis-van Creveld syndrome have been followed at the Pediatric Dentistry Service of the Hospital Sant Joan de Déu, Barcelona. The present study describes the constant and variable oral findings in these patients, which play an important role in the diagnosis criteria for the syndrome. The presence of a great variety of oral manifestations such as fusion of the upper lip to the gingival margin, presence of multiple frenula, abnormally shaped and microdontic teeth, and congenitally missing teeth requires multidisciplinary dental treatment, with consideration for the high incidence of cardiac defects in these patients.

The role of digital volume tomography in the imaging of impacted teeth.

AIM: Digital volume tomography is presented here as an alternative to routine computerized tomography in the diagnosis and treatment planning of impacted teeth. MATERIAL AND METHODS: A sample of 20 patients with a variety of types of tooth impaction was investigated and five representative cases are described. The potential disadvantages of digital volume tomography--inferior spatial resolution of subtle structures and limited representation of soft tissues--were of no clinical significance in the presented cases of impacted teeth. The method provides 3-dimensional images closely akin to regular computerized tomography imaging, yet the amount of radiation produced is less than one sixth that for regular computer tomography and its cost is considerably less. RESULTS AND CONCLUSION: There is reason to recommend the routine adoption of digital volume tomography imaging for positional diagnosis in most cases of impaction of teeth that are candidates for orthodontic resolution.

Use of the apically repositioned flap in the management of labially impacted maxillary central incisors.

Management of labially impacted maxillary central incisors often requires a coordinated surgical and orthodontic approach. In such cases, the treatment objective is surgical exposure of the unerupted incisor, preferably with a functional width of keratinized gingiva on the labial surface. Tooth exposure is then followed by orthodontic intervention to move the tooth to the line of occlusion. This paper describes three cases where the apically repositioned flap technique was used to manage labially impacted maxillary central incisors.

Natal and neonatal teeth.

Tooth eruption follows a chronology corresponding to the date when the tooth erupts into the oral cavity. This date has been established in the literature and is subject to small variations depending on hereditary, endocrine and environmental features. Any disturbance during the development of the teeth -systemic or local- can affect not only the morphology, structure of dental hard tissues or number of teeth but also the time of eruption. The presence of a tooth in the mouth at birth or during the first month of life has been studied and denominated as natal and neonatal teeth. The aim of this paper is to review current information on this topic and to give treatment alternatives if it is necessary.

Location, complications and treatment of mesiodentes--a retrospective study in children.

Out of approximately 11 500 children, who had been referred to the Department of Paediatric Dentistry at the Institute for Postgraduate Education,Jönköping, Sweden, 97 individuals had a total of 123 mesiodentes. Their dental records and radiographs were analysed in order to study the clinical and radiographic features of the mesiodentes, to record the complications caused by them and to evaluate different forms of treatment. In the present study, the predominant location of the mesiodentes was palatally with 39 per cent in an inverted position. Arrest of the permanent incisors eruption, midline diastema and displacement or rotation of the incisors, were the most common complications found. On the contrary, no follicular cysts or resorption of either the mesiodens or the adjacent teeth were found. Fourty-three out of the 97 individuals were radiographically followed and no pathological findings were recorded. This study shows that the risk of complications caused by the mesiodentes seems to be very low and therefore a more restrictive attitude towards their surgical removal can be recommended.
