1/150. Treatment of an impacted dilacerated maxillary central incisor.

    Impacted incisor With Dilaceration refers to a dental deformity characterized by an angulation between crown and root causing noneruption of the incisor. Surgical extraction used to be the first choice in treating the severely dilacerated incisor. In this article, a horizontally impacted and dilacerated maxillary central incisor was diagnosed radiographically. By combining two stages of the crown exposure surgery with light force orthodontic traction, the impacted dilacerated incisor was successfully moved into proper position. However, long-term monitoring of the stability and periodontal health is critical after orthodontic traction.

2/150. Single central maxillary incisor with nasal pyriform aperture stenosis--CT diagnosis prior to tooth eruption.

    Two children with nasal pyriform aperture stenosis had the diagnosis of single central maxillary incisor made with CT scanning prior to tooth eruption and the clinical appreciation of this finding. The surgical and clinical implications of this diagnosis will be presented.

3/150. Primary failure of tooth eruption: a unique case.

    Primary failure of tooth eruption rarely occurs. This case represents a rare clinical situation and appears to reflect a generalized disturbance in the eruptive process, inasmuch as (1) deciduous and permanent dentition are affected, (2) incisors, molars, and premolars are involved in all quadrants, (3) skeletal and craniofacial growth are within normal limits, and (4) no systemic/genetic anomalies were detected. This is the first such case reported in the literature; diagnosis and management are discussed.

4/150. Anomalies of craniofacial skeleton and teeth in cleidocranial dysplasia.

    Mutations involving the transcription factor CBFA1 cause cleidocranial dysplasia (CCD) in man. Recently, a mouse model of CCD has been generated (Cbfal /-) [Komori et al., 1997], and disturbances of osteoclast differentiation have been documented. It has been shown that these animals exhibit hypoplastic clavicles and nasal bones, and retarded ossification of parietal, interparietal, and supraoccipital bones. humans with CCD show all these features, including severely retarded ossification of the cranial base, strongly suggesting that both intramembranous ossification and endochondral ossification are affected. In addition, CCD patients have multiple supernumerary teeth and delayed tooth eruption. The present report presents 3D reconstructions of computerised tomography (CT) scans of the craniofacial region of a CCD boy examined at both 1 and 7 years of age. The anomalies in craniofacial skeleton and teeth are analysed and compared to the findings of our previous clinical studies and to the findings in the animal model. Based on the available information, we suggest that osteoblast, osteoclast, and dentinoclast differentiation may be disturbed in CCD.

5/150. Molarization of the lower second premolars.

    This paper presents a case of extreme tooth variation. The patient was first observed during the mixed dentition period, when she presented a mild Class II malocclusion with increased overjet and acceptable overbite. In a panoramic radiograph, the presence of lower second premolars of disproportionate dimensions was discovered. When these oversized premolars erupted, the Class I malocclusion tended toward Class III, with an edge-to-edge bite. This created an unstable occlusion and the possible need for extractions.

6/150. incontinentia pigmenti (Bloch-Sulzberger syndrome): report of case.

    incontinentia pigmenti is an inherited disorder with predominantly ectodermal abnormalities. The dental effects, delayed eruption, hypodontia, and microdontia, are very similar to anhidrotic ectodermal dysplasia. It is important that children with incontinentia pigmenti gain access to specialist dental care including pediatric dentistry, orthodontics, prosthodontics and oral surgery.

7/150. Clinical problems associated with unusual cases of talon cusp.

    CASE REPORT: Talon cusp is an uncommon dental anomaly manifested as an accessory cusp-like structure on the crown of anterior teeth. This report describes two unusual cases of talon cusp. Case 1 showed bilateral anomalous cusps on the palatal aspects of maxillary supernumerary teeth, causing premature contact and tooth impaction. In case 2, a double-fused talon cusp was projected from the palatal surface of a large geminated central incisor. A talon cusp is not an innocuous defect, as it may provide a substantial diagnostic, treatment planning and procedural challenge. early diagnosis and management are important to avoid complications.

8/150. Dysosteosclerosis: a case with unique dental findings and SEM evaluation of a hypoplastic tooth.

    A ten-year-old boy, who had the typical dental findings of dysosteosclerosis such as yellowish, hypoplastic teeth, retarded eruption, which upon eruption, decayed rapidly, is presented. To date this is the first known case reported with a congenital absence of the first permanent molars. Furthermore, SEM evaluation of the enamel and dentin was performed on a tooth from a patient with dysosteosclerosis for the first time. These studies showed weak ultrastructural compositions due to irregular calcification.

9/150. Lowe syndrome: case report.

    Lowe syndrome is a genetic multi-system disorder affecting the central nervous system, lens and kidney. In this report, constricted palate, multiple eruption cysts and hematomas as the oral findings of a child diagnosed with Lowe syndrome is presented.

10/150. Globodontia in the otodental syndrome.

    A family of Polish extraction was studied in which massive, globe-shaped posterior teeth were found in a father and two of his sons, similar to those described in a previous family in which persons with this type of teeth also had a high-frequency sensorineural deafness. The audiograms in this family showed high-frequency air-conduction thresholds in the father and one son with globodontia and in other relatives without the tooth defect. The other son with abnormal teeth had a normal-appearing audiogram. Absence of premolar teeth and yellow-white spots of local hypomaturation of enamel on canine teeth were also findings in this kindred, as reported or observed in other kindreds. The disorder illustrates the problem of variable expressivity of a trait which makes it difficult to predict the risk of having an affected child when only one feature of a syndrome is present in a relative of a fully affected patient.
