1/20. 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.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/20. 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.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/20. 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.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/20. Enamel pearls and cervical enamel projections on 2 maxillary molars with localized periodontal disease: case report and histologic study.Presented here is an unusual case of teeth with aberrant enamel. One small and 3 large enamel pearls were identified in 2 maxillary third molars of a patient. One long enamel projection was connected to one of the large enamel pearls, along with 2 short cervical enamel projections. The ectopic enamel was associated with advanced localized periodontal destruction. After extraction, the molars were investigated radiographically and under the scanning electron microscope. The 3 large pearls contained distinct dentinal cones. The enamel of the pearls and the long cervical projection exhibited most of the structural attributes of crown enamel but were somewhat irregular, with variable shape and course of the prisms. Morphologic considerations suggest that these enamel pearls were aberrations and should not be regarded as attempts at new cusp or new tooth formation.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/20. Ellis van Creveld syndrome (chondroectodermal dysplasia, MIM 22550) in three siblings from a non-consanguineous mating.The major diagnostic features of Ellis van Creveld syndrome (EvC) includes disproportionate short stature, polydactyly, ectodermal anomalies, and structural heart defects. We describe three siblings with EvC of a non-consanguineous mating. The history of these siblings well illustrate the clinical manifestations and complications that children with EvC encounter. All three girls had short stature, narrow rib cage, polydactyly and nail hypoplasia. The first daughter died in early infancy in respiratory failure. The second daughter underwent open heart surgery for atrial septal defect repair. The third daughter, diagnosed in utero with fetal ultrasonography, currently is scheduled for surgical excision of extra-digits and extraction of neonatal teeth. infant mortality rates among patients with EvC is strikingly high due primarily to cardiorespiratory failure. If they survive infancy morbidity is significant. The gene effected in individuals with EvC has recently been identified on the short arm of chromosome 4. Future testing for gene mutations may provide valuable information for premarital counseling and prenatal diagnosis. Three offspring with disproportionate short stature, polydactyly, and ectodermal dysplasia of a non-consanguineous mating, strongly indicate parental heterozygosity for Ellis van Creveld syndrome.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/20. Characteristics and dental treatment of partial trisomy 9.A description is made of the dental characteristics and treatment of a patient with partial trisomy 9. Due to the deep mental retardation and motor deficiency of the patient involved, treatment (extractions, caries restorations and periodontal treatment) is conducted in hospital and under general anesthesia. trisomy 9 has only rarely been described in literature, and the present study provides one of the first descriptions of both the dental characteristics of these patients and the treatment of their oral pathology.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/20. Oro-dental manifestations of the Schwartz-Jampel syndrome.A boy with the Schwartz-Jampel syndrome (chondrodystrophic myotonia) had a number of oro-dental complications. These included difficulty in tooth extraction and orthodontic care due to a small oral aperture and rigidity of the temporo-mandibular joints. General anaesthesia was hazardous because of a propensity to malignant hyperthermia, and endotracheal intubation was difficult because of shortness and rigidity of the neck and the small size of the laryngeal structures. awareness of these potential problems is crucial for anaesthesia and comprehensive dental management. The radiological demonstration of dentigerous cysts is a hitherto unreported observation in this disorder.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/20. Endodontic management of dens evaginatus of maxillary central incisors: a rare case report.Dens evaginatus is a disturbance in tooth development that produces a tubercle of hard tissue on the surface of the tooth. While prophylactic pulp capping is recommended for vital teeth, teeth with necrotic pulps require endodontic therapy or extraction. This rare case of a 24-yr-old Indian male with affected maxillary central incisors demonstrates the clinical consequences of dens evaginatus.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/20. Managing morphologically atypical impacted teeth orthodontically.Impactions with severely dilacerated root is seldom reported, especially the maxillary incisor. It is probably because of the high clinical difficulty of bringing the dilacerated tooth into position: most patients probably would choose extraction with replacement by prosthesis instead. However, the philosophy seems to have changed recently. We report two cases one in which an impacted central incisor was brought in the arch by orthodontic traction. In the second case the impacted premolar was brought into the arch and was shaped as a mandibular canine for achieving a good functional occlusion.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/20. cleidocranial dysplasia: diagnostic criteria and combined treatment.cleidocranial dysplasia (CCD) is an uncommon, generalized skeletal disorder characterized by delayed ossification of the skull, aplastic or hypoplastic clavicles, and serious, complex dental abnormalities. There are many difficulties in the early diagnosis of CCD because a majority of the craniofacial abnormalities becomes obvious only during adolescence. In the present case, a hypoplastic midface, a relative prognathia of the mandible, and close approximation of the shoulders in the anterior plane were the conspicuous extraoral findings. Prolonged exfoliation of the primary dentition, unerupted supernumerary teeth, and the irregularly and partially erupted secondary dentition produced occlusional anomalies. The presence of the second permanent molars together with the primary dentition and wide spacing in the lower incisor area were typical dental signs. Gradual extraction of the supernumerary teeth and over-retained primary teeth was the first step of oral surgery. This was followed by a surgical exposure of the unerupted teeth by thinning of the cortical bone. Orthodontic treatment was aimed at parallel growth of the jaws. Removable appliances were used to expand the narrow maxillary and mandibular arches, and a Delaire mask compensated for the lack of sagittal growth of the upper jaw. Temporary functional rehabilitation was solved by partial denture. When the jaws have been fully developed, implant insertions and bridges are the therapeutic measures. The reported case and the literature data support the importance of the early diagnosis and interdisciplinary treatment of CCD.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
