1/67. Localized deficient root development associated with taurodontism: case report.Dentinal dysplasia type I (DDI) is a rare disturbance in dentin formation. This case report illustrates different radiographic features from other reported DDI cases in that only one quadrant (lower right posterior teeth) has the characteristic of DDI and both right and left upper molars exhibit taurodontism. This finding might be a variation of DDI. However, it is possible that this type of developmental defect could occur because of regionalized abnormalities in cellular function and proliferation as occurs in regional odontodysplasia.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
2/67. Implant-surgical and prosthetic rehabilitation of patients with multiple dental aplasia: a clinical report.The expanded experience with oral implants and supplementary augmentation techniques has opened new possibilities for treating patients with oligodontia or anodontia with fixed prostheses. A problem in treating such patients is the need to place implants in growing maxillae or mandibles, as many of these patients are children or adolescents. When implant treatment is postponed until the patient is full grown, dysfunctions become manifest, which necessitates extensive surgical measures to achieve a fixed prosthetic restoration. This report illustrates the problems associated with different concepts for the treatment of multiple aplasia with implants. The results are based on the findings of 22 patients with oligodontia who underwent surgical treatment and were followed over a period of 5 years. Two controversially treated cases are presented.- - - - - - - - - - ranking = 117.31231738495keywords = mandible (Clic here for more details about this article) |

4/67. Partial anodontia in a case of Waardenburg's syndrome.On routine examination of a case of Waardenburg's syndrome apart from the usual features of the disorder, partial anodontia involving both the lower lateral incisors was evident. The interesting association of partial anodontia and Waardenburg's syndrome is discussed along with relevant available literature.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
5/67. Implant anchorage for the occlusal management of developmental defects in children: a preliminary report.Congenital anomalies and developmental defects of the face and jaws often present orthodontic anchorage challenges in which the residual dentition cannot be adequately positioned for restorative objectives. This article presents a method of classification for the formulation of implant-based treatment protocols in children, reviews the application of implants in the developing dentition, and provides guidelines for occlusal treatment. Procedures performed according to the protocols outlined in this article will facilitate orthodontics and orthopedic movement and accelerate three-dimensional jaw movement by sutural distraction of basal bone.- - - - - - - - - - ranking = 26.704222059898keywords = jaw (Clic here for more details about this article) |
6/67. Severe hypodontia: diversities in manifestations.The material comprises 33 cases, 12 boys and 21 girls with 4 or more lacking teeth in the permanent dentition, randomly collected among patients referred to the Department of Pedodontics, University of Bergen. The total number of lacking teeth were 332, mean number in boys was 11.4, in girls 9.3, ranging from 4 to 24 (third molars excluded). The most prevalently lacking teeth were second premolars in both jaws, maxillary lateral incisors, mandibular central incisors and maxillary first premolars. The maxillary central incisors were the most stable teeth, lacking in only one patient. The female group was closest to this "classical" scheme by lacking teeth mostly in posterior segments. In males the anterior segments were most often afflicted. There was no significant difference between right and left sides in both sexes, but in girls the maxillary jaw was more afflicted than the mandibular jaw. The individual analyses of cases showed great diversities in the manifestation of hypodontia. Eighteen of them behaved fairly "balanced" with respect to lack of teeth in the different quadrants. Six cases were lacking most of the teeth in the maxillary jaw (total 34 maxillary teeth versus 11 mandibular). Five cases were lacking most of the teeth in the mandibular jaw (total 30 mandibular teeth versus 14 maxillary). One patient was lacking 10 of his 12 front teeth, but only 4 of his 20 posterior teeth, and one patient was lacking 12 of his 16 posterior teeth, but none of his front teeth. The author cannot offer any explanation for these strange and varying patterns of manifestations.- - - - - - - - - - ranking = 66.760555149744keywords = jaw (Clic here for more details about this article) |
7/67. Osseointegrated implants in a patient with Papillon-Lefevre syndrome. A 4 1/2-year follow up.BACKGROUND: The Saudi female reported in this study was diagnosed with Papillon-Lefevre syndrome. She had lost all her teeth, including third molars, at the age of 18 years. METHOD: She was wearing full dentures for 7 years, before 5 titanium implants were installed in the mandible. RESULTS: 4 1/2 years after the implant installation, the treatment was clinically and radiographically successful. Neither A. actinomycetemcomitans nor P. gingivalis were detected at any of the implants. This very encouraging result does not differ from what is generally reported in edentulous medically healthy patients. CONCLUSION: The use of implants could considerably enhance future therapeutic options for the severely dentally compromised patients with Papillon-Lefevre syndrome.- - - - - - - - - - ranking = 117.31231738495keywords = mandible (Clic here for more details about this article) |
8/67. The dentofacial manifestations of XXXXY syndrome: a case report.This paper presents a six-year-old patient with XXXXY syndrome, whose oral findings included a cleft soft palate, hyper- or meso-taurodontism in eight primary molars and in the mandibular permanent first molars, five congenitally missing premolars, and delayed development of the permanent tooth germs. The maxillary and mandibular primary central incisors were in a cross-bite relationship. Cephalometric findings showed a short ramus of the mandible and a short maxilla in the anterioposterior plane. The anteroposterior jaw relationship was in harmony. The cross-bite was considered to be due to the retroinclination of the maxillary primary incisors. This case emphasises the importance of regular dental care, and monitoring of facial growth and dental development in children with XXXXY syndrome.- - - - - - - - - - ranking = 130.6644284149keywords = mandible, jaw (Clic here for more details about this article) |
9/67. Craniofacial characteristics of klippel-feil syndrome in an eight year old female.A female eight year, one month old patient with klippel-feil syndrome has been introduced. General appearance of the patient was characterized by short neck with limited head movements, craniofacial asymmetry, low posterior hairline and a short stature. Cephalometric analysis revealed a Class I dentoskeletal pattern with an excessive mandibular plane angle and fused cervical vertebrae. Panoramic radiogram showed congenitally missing lower second premolars and right central incisor.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
10/67. A rare non-syndrome case of concomitant multiple supernumerary teeth and partial anodontia.Concomitant hypo-hyperdontia is an uncommon condition of coexistence of partial anodontia and supernumerary teeth. Its etiology is still unknown. Very few cases have been reported in the literature of this condition. Presented here is a rare and first such case of simultaneous presence of multiple supernumerary teeth and a missing tooth (canine) without any associated systemic conditions or syndromes involving both jaws.- - - - - - - - - - ranking = 13.352111029949keywords = jaw (Clic here for more details about this article) |
