1/15. Malformation in the primary and permanent dentitions following trauma prior to tooth eruption: a case report.Dento-facial injuries that occur prior to the eruption of teeth in the primary dentition are rare, but can result in damage to the primary dentition. We report a rare case where an injury to the anterior maxilla and mandible of an infant prior to primary tooth eruption resulted in hypoplasia, displacement and impaction of the primary dentition and damage to a developing permanent tooth.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/15. Patterns of intra-osseous transmigration and ectopic eruption of mandibular canines: review of literature and report of nine additional cases.OBJECTIVES: The purpose of this study is to (1). investigate the patterns of transmigration and eruption of permanent mandibular canines, plus the mechanisms affecting the eruption path, (2). classify the transmigration paths. MATERIAL AND methods: :A retrospective radiographic study using full mouth (FMX) and panoramic radiographs of dental radiology patients between July 1996 and July 2000. Transmigrated canines were identified from the radiographic records of 2150 new patients. The literature was reviewed regarding the individual patterns of canine transmigration and their final position within the mandible. A pattern classification was developed using literature data and the additional nine cases reported here. RESULTS: In the present study, mandibular canines were found transmigrated on nine occasions and, in a further six cases, found impacted without transmigration. Out of the nine cases, seven were female (ages 17-38) and two were male (ages 20 and 69). One female patient had a bilateral transmigration of the mandibular canines. A total of 127 transmigrated canines were reported in 50 published studies from the literature. Transmigrated canines appear to fall into five patterns (Type 1-5) depending on their path of deviation. Type 1 was most common (45.6%) followed by Type 2 (20%), Type 4(17%), Type 3(14%) and Type 5 (1.5%). CONCLUSIONS: Patterns of mandibular canine transmigration can be classified into five distinct patterns. The majority of cases demonstrated Type 1 transmigratory pattern. No clear aetiology of this disorder could be found.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
3/15. An atypical Hallermann-Streiff syndrome. Focus on dental care and differential diagnosis.The Hallermann-Streiff syndrome (HSS) is a rare congenital disorder characterized by dyscephaly, birdlike facies, hypoplastic mandible, congenital cataracts, microphthalmia, hypotrichosis, skin atrophy, proportionate short stature, and dental anomalies. A case of a 29-year-old man with atypical HSS with neither cataracts, hair and skin alterations, nor short stature is reported, with special consideration to oral findings and dental management. Dental extractions, scaling, restorations, and endodontics were performed under local anesthesia. Later, orthodontic rehabilitation with fixed brackets was carried out. Finally, a removable partial denture for the maxillary arch was designed using transparent acrylic, and this also served as a retention splint. Young patients with HSS and other similar syndromes must be involved in personalized oral health prevention programs as early as possible. Despite numerous systemic anomalies, some of these patients may undergo conventional dental procedures under local anesthesia in the dental office.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
4/15. Extraoral inverted teeth eruption: a case report.A 14-year-old female presented with extraoral inverted eruption of left mandibular permanent molars 18 and 19 at the lower left inferior border of the mandible. Both the teeth started erupting 1 year after an extraoral surgical intervention for a discharging sinus 6 years ago. The subsequent eruption to the extraoral position of the permanent molars at the inferior border of mandible may be the result of the previous surgical procedure or pathology related to the abnormally positioned teeth. This case presents an infrequent complication affecting the adjacent permanent teeth.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
5/15. Sporadic Burkitt's lymphoma of the jaws: the essentials of prompt life-saving referral and management.Burkitt's lymphoma is an undifferentiated non-Hodgkin's B-cell lymphoma. Three clinical subtypes are recognized: African (endemic), American (sporadic) and hiv associated. Sporadic Burkitt's lymphoma is a rare malignancy among western populations.This report describes a case of sporadic Burkitt's lymphoma of the jaws with an alarmingly rapid spread associated with acute renal failure. This type of rapid progression bespeaks the need for prompt recognition and life-saving referral by the dental practitioner. The clinical features of Burkitt's lymphoma involving the jaws include severely hypermobile, ectopically displaced and supra-erupted teeth.The purpose of this case report and review of the literature is to illustrate the clinical and histopathologic features of Burkitt's lymphoma to help clinicians recognize such cases readily and facilitate prompt and potentially life-saving referral.- - - - - - - - - - ranking = 1.185084320507keywords = jaw (Clic here for more details about this article) |
6/15. Unusual intraosseous transmigration of a palatally impacted canine.Intraosseous migration of impacted teeth across the midline to the opposite side of the jaw is a rare dental anomaly of unknown etiology. Transmigration of an impacted mandibular canine through the symphysis to the contralateral side of the arch has been documented. Transmigration of an impacted maxillary canine across the midpalatal suture to the opposite side of the maxilla has not been previously observed and is reported here for the first time.- - - - - - - - - - ranking = 0.19751405341784keywords = jaw (Clic here for more details about this article) |
7/15. Management of an extremely displaced maxillary canine.CASE REPORT: Aligning a displaced maxillary canine into the dental arch is one of the most complicated problems in orthodontics. In cases of extremely high displacement, the tooth is frequently removed surgically. Because of the upper canines' significance to dental esthetics and functional occlusion, such a decision is a very serious one. This case report illustrates the treatment of an extremely high displaced maxillary canine. CLINICAL FINDINGS: The main diagnosis was the displacement and the retention of tooth 13 (in nearly horizontal position, apical to the neighboring teeth); further diagnoses were: transversal maxillary deficiency with frontal crowding and a distal bite of one premolar in width, a deep bite of 6 mm with contact in the palatal mucosa, mandibular midline deviation of 2.5 mm to the right, lingual eruption of teeth 32 and 42, retroinclination of the maxillary incisors, and retarded eruption of the permanent teeth. THERAPY: Initial treatment with active and functional appliances to correct the distal bite, midline deviation and deep bite. Surgical exposure of the high displaced canine at the age of 14. Onset of cuspid elongation with removable appliances and elastics, further movement with a transpalatinal bar and welded arm, and full alignment of the upper and lower arches with fixed appliances in both jaws. Stabilization of the orthodontic treatment results with retention devices. Duration of treatment: 5 years and 8 months. For the alignment of tooth 13, 2 years and 10 months were required; 1 year and 4 months were necessary with complete fixed appliance. CONCLUSIONS: The aim of this case report was to demonstrate the potential of aligning an extremely displaced canine. Because of the esthetic and functional importance of the upper canines, therapeutic alignment should be initiated, provided there are no indications to the contrary.- - - - - - - - - - ranking = 0.19751405341784keywords = jaw (Clic here for more details about this article) |
8/15. Transmigration of permanent mandibular canines. Case report.Transmigration is the migration of a tooth across the midline of the jaw. This phenomenon is found only in relation to the permanent mandibular canines. Two cases are reported. In both, the cause of this deviation was an odontome found in the site normally occupied by the mandibular canine. The literature on transmigration is reviewed.- - - - - - - - - - ranking = 0.19751405341784keywords = jaw (Clic here for more details about this article) |
9/15. American Burkitt's lymphoma: a 10-year review and case study.Burkitt's lymphoma is a malignancy of B-lymphocyte origin that was initially described in African children with jaw tumors. These tumors often spread to involve abdominal viscera and other sites, have rapid growth kinetics, and are principally responsive to chemotherapy. Prolonged survival is predicted by site and extent of tumor, with bone marrow and central nervous system involvement being indicators of a poor prognosis. The dental practitioner plays an important role in diagnosis of jaw lesions and treatment throughout the course of the disease. An examination of 17 cases of Burkitt's lymphoma diagnosed at The North Carolina Memorial Hospital, University of north carolina at Chapel Hill, north carolina, over a 10-year period is undertaken and an illustrative case study is presented to demonstrate the challenge of caring for the patient with Burkitt's lymphoma.- - - - - - - - - - ranking = 0.39502810683567keywords = jaw (Clic here for more details about this article) |
10/15. Canine transposition--approaches to treatment.Transposition, an infrequently occurring dental anomaly, almost always involves the canines. Transposition occurs in either jaw, bilaterally or unilaterally, and in most cases the primary canine is still present. The canine may transpose with the lateral incisor or the first premolar. In the maxilla, transposition with the first premolar occurs more frequently. In the mandible, as far as can be determined, the canine always transposes with the lateral incisor. Several causative factors have been discussed. When cases of incipient transposition are detected early enough they can sometimes be treated interceptively. When seen at later stages, the positions of the root apexes are important for a decision about where to move the transposed teeth.- - - - - - - - - - ranking = 1.1975140534178keywords = mandible, jaw (Clic here for more details about this article) |
