1/21. 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 = deformity (Clic here for more details about this article) |
2/21. Familial hypophosphatemic vitamin d-resistant rickets: dental findings and histologic study of teeth.A case of familial hypophosphatemic vitamin d-resistant rickets or X-linked hypophosphatemia (XLH) accompanied by specific systemic and dental findings is reported. A 15-year-old boy with XLH visited our facility complaining of a toothache in the left lower canine region. Two other family members of the patient, his younger sister and their mother, also had XLH, whereas the other 2 members, his younger brother and father, are healthy. Those with XLH show systemic signs of the disease, such as growth retardation, limb deformity, and spinal curvature disorders; however, these symptoms are more severe in the patient than in the others. The patient had multiple periodontal abscesses, but no evidence of dental caries, trauma, or periodontal disease on the corresponding teeth at the time of his oral examination. A radiographic examination showed root dysplasia and enlarged pulp chambers.A histologic examination of an extracted third molar showed marked globular dentin and an increased predentin width. The abscess was thought to be caused by pulpal infection, which came from bacterial invasion through enamel cracks and dentinal microcleavage of the teeth. The treatments provided in this case are discussed.- - - - - - - - - - ranking = 1keywords = deformity (Clic here for more details about this article) |
3/21. Impaired dentofacial development after radiotherapy of a non-Hodgkin lymphoma: report of case.Since the advances in therapy of childhood malignancies have improved life expectancy attention is now increasingly focused on the long-term effects of antineoplastic therapy. Developmental abnormalities due to antineoplastic therapy have been claimed to preferentially occur in children treated before the age of six years. This report of a case demonstrates severe developmental disturbances following radiotherapy of a cervical non-Hodgkin lymphoma at the age of eight years. The morphological changes included microdontia, root shortening, blunting and thinning as well as mandibular hypoplasia.- - - - - - - - - - ranking = 3309.1731245692keywords = dentofacial (Clic here for more details about this article) |
4/21. 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 = 3309.1731245692keywords = dentofacial (Clic here for more details about this article) |
5/21. Biometric and magnetic resonance imaging assessment of dentofacial abnormalities in a case of klippel-trenaunay-weber syndrome.klippel-trenaunay-weber syndrome is characterized by cutaneous hemangioma, arteriovenous fistulas or varicosities (or both), and unilateral hypertrophy of hard and soft tissues with different localization. klippel-trenaunay-weber syndrome represents a syndrome of interest for those in the fields of oral and maxillofacial radiology and pathology because of the high incidence of compromise of the orofacial area in affected patients. The patient reported here presents with all of the 3 characteristic signs of the syndrome. The somatic and facial hypertrophy is contralateral to angiomata. As revealed through the use of magnetic resonance imaging, the primary component of facial hypertrophy is adipic subcutaneous tissue. Statistical analysis of the dental dimensions revealed that teeth on the hypertrophic side are significantly larger than normal.- - - - - - - - - - ranking = 3309.1731245692keywords = dentofacial (Clic here for more details about this article) |
6/21. Craniofacial morphology in an unusual case with nasal aplasia studied by roentgencephalometry and three-dimensional CT scanning.OBJECTIVE: To examine the three-dimensional morphology of internal structures of the craniofacial region and present the orthodontic problems in an unusual case with nasal aplasia. PATIENT: The patient was an 11.5-year-old boy with aplasia of the nose and nasal cavity with extremely constricted nasopharyngeal airway. He did not have mental or somatic retardation. The patient had dacryostenosis. The morphology of the craniofacial structures was characterized by absence of septal structures, including cribriform plate, perpendicular plate of ethmoid bone, vomer, and septal cartilage; bony hypotelorism; midface hypoplasia; short and retrognathic maxilla with Class III jaw relationship; average mandibular plane angle; high arched palate; severe anterior open bite with bilateral posterior crossbites; and dental anomalies (agenesis of four maxillary permanent teeth, microdontia, taurodontism, and short roots). Thus, the patient had characteristic dentofacial phenotype, which might be caused by a combination of the primary anomaly and the functional disturbances secondary to the nasal obstruction.- - - - - - - - - - ranking = 827.2932811423keywords = dentofacial (Clic here for more details about this article) |
7/21. The dentofacial features of Sanjad-Sakati syndrome: a case report.Sanjad-Sakati syndrome is an autosomal recessive disorder that was first reported by Sanjad et al. in 1988. It is characterized by congenital hypoparathyroidism, severe growth failure and dysmorphic features. The clinical features include deep set eyes, microcephaly, thin lips, depressed nasal bridge with beaked nose, external ear anomalies and learning difficulties. This report presents the case of a 4-year-old patient who was referred to our dental clinic because of pain in her mouth and poor dental health. Oral findings included micrognathic mandible and maxilla, microdontia, enamel hypoplasia as well as severely decayed teeth. Treatment was carried out under general anaesthesia to extract the most severely affected teeth and restore those which could be conserved. It was concluded that these patients have special dental needs; early diagnosis of the affected children is therefore important in order to commence preventive dental therapy and carry out appropriate dental treatment at the optimum time.- - - - - - - - - - ranking = 3309.1731245692keywords = dentofacial (Clic here for more details about this article) |
8/21. Dental alterations associated with X-linked hypophosphatemic rickets.The X-linked hypophosphatemic rickets is a rare metabolic disorder characterized by low serum phosphate levels caused by a decreased renal tubular reabsorption of inorganic phosphates. The initial complaints are a delay in the development of walking caused by deformity of the legs. Oral findings include poorly mineralized dentin, enlarged pulp chambers and root canals, and periradicular abscesses in caries-free teeth. We present three patients from the same family with X-linked hypophosphatemic rickets showing bone and dental alterations.- - - - - - - - - - ranking = 1keywords = deformity (Clic here for more details about this article) |
9/21. A previously unreported association between Nance-Horan syndrome and spontaneous dental abscesses.Atypical dentofacial structures may be the first indicator of other anomalies linked to a syndrome. This case describes the management of a 9-year-old girl referred for the routine management of supernumerary teeth. The anomalous form of her teeth, together with multiple supernumerary units and a history of congenital cataracts, were suggestive of a diagnosis of Nance-Horan syndrome. This is an X-linked disorder, in which females usually demonstrate mild expression; this case was unusual in respect to the marked phenotype expressed. Unusually, the girl developed 2 spontaneous abscesses of her noncarious upper incisor teeth; a feature never previously described in this syndrome. This report details the patient's dental management and discusses the possible pathogenesis of the dental abscesses, together with the genetic implications of this syndrome.- - - - - - - - - - ranking = 827.2932811423keywords = dentofacial (Clic here for more details about this article) |
10/21. Ectopic supernumerary tooth on the inferior nasal concha.Variations regarding the location of an ectopic tooth in the human nasal cavity, although rare, are documented in the literature, but presence of an ectopic tooth on the inferior nasal concha (INC) has not been reported. We observed an anomalous tooth projecting from the posterior margin of the right INC in two adult female skulls. A small quadrangular tooth projected beyond the posterior margin of the hard palate in one of the skulls and a medium sized conical tooth was observed in the other skull. The affected INC in both skulls were located more inferiorly compared to the opposite side and were in close approximation with the hard palate. No similar findings were noted on the contralateral side nor were there any associated congenital or iatrogenic deformity. The phylogenetic, ontogenetic, and clinical importance of this variant is described. knowledge of such an anomaly is of paramount importance to otorhinolaryngologists, reconstructive and dental surgeons, and radiologists for identification of such rarities encountered during invasive or non-invasive procedures.- - - - - - - - - - ranking = 1keywords = deformity (Clic here for more details about this article) |
