1/52. 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) |
2/52. The use of gutta-percha point to locate the origin of facial sinus.infection from the wisdom teeth usually causes severe swelling at the region of the angle and body of the mandible. Occasionally, it tracts outward to form a cervicofacial sinus. This paper demonstrates the use of gutta-percha point to locate the origin of a cervicofacial sinus due to an asymptomatic impacted wisdom tooth. The advantage of using gutta-percha point is discussed.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
3/52. 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 = 0.084512226674895keywords = jaw (Clic here for more details about this article) |
4/52. myxoma of the jaws. Report of three cases.Odontogenic myxoma is a locally aggressive, uncommon benign tumour which arises from mesenchymal tissues normally present in developing teeth. The most frequent locations of odontogenic myxoma are the posterior regions of the mandible, as well as the condylar region. Since odontogenic myxomas are not associated with any specific clinical or radiological sign, a histopathological examination of the specimen is required for confirmation of the primary diagnosis. We report three cases of myxoma diagnosed during the last 18 years. Two of them were located in atypical regions of the mandible and one was located in the maxilla. Presence of a slow-growing swelling associated with expansion of the bone plates raised suspicion of a tumour in two cases, while in the third patient the myxoma was an incidental finding during radiological examination. Due to the unspecific nature of these lesions, in every case a histopathological examination of the surgical specimen was required for diagnostic confirmation. In one of the three reported cases, we shall underline the need to follow a correct diagnostic work-up of all radiolucent lesions of the jaws, in order to avoid contraindicated therapeutic procedures.- - - - - - - - - - ranking = 2.4225611333745keywords = mandible, jaw (Clic here for more details about this article) |
5/52. Spaced dentition--open, close or redistribute?A spaced dentition can be due to various reasons such as hypodontia, tooth size discrepancy and impeded eruption. The dilemma for clinicians is whether to close, open or redistribute space. Closing space by orthodontics eliminates the need for prosthetic rehabilitation but it might compromise aesthetics and function. On the other hand, opening space is more complex and requires long-term maintenance. Based on these drawbacks, a careful occlusal analysis and an individualized treatment plan are mandatory for achieving the best result. The prognosis for closing space and substituting congenitally missing maxillary laterals with canines depends on factors such as overjet, lip support, crown colour, shape and root position. If these are unfavourable, opening space for prosthetic replacement is then preferred. Discrepancy between tooth and jaw size results either in spacing or crowding. The location of the spacing and the amount of overjet are important factors guiding the direction of treatment.- - - - - - - - - - ranking = 0.084512226674895keywords = jaw (Clic here for more details about this article) |
6/52. Primary intraosseous carcinoma associated with impacted third molar of the mandible: review of the literature and report of a new case.This study investigated the clincopathologic features of primary intraosseous carcinoma (PIOC) related to the third molar of the mandible. Six cases (5 from the literature and 1 new case; mean patient age 73 years) of PIOC associated with completely impacted lower third molar were analyzed. For comparison, 8 cases of PIOC presenting after extraction of the lower third molar were also evaluated, with a significantly lower mean patient age of 56 years. Most lesions were deceptively similar to those related to the lateral type of dentigerous cyst, and half of the impacted cases revealed an asymptomatic fracture of the mandible. In all patients except for the present case, metastasis had not been recorded. Surprisingly, no patients are known to have died of PIOC. In our experience the prognosis of PIOC associated with a completely impacted third molar is much better than commonly believed, although the number of cases involved is too small to make a general conclusion. However, delay in establishing the correct diagnosis followed by extraction without awareness of the carcinoma is know to adversely affect the prognosis.- - - - - - - - - - ranking = 6keywords = mandible (Clic here for more details about this article) |
7/52. Preoperative application of limited cone beam computerized tomography as an assessment tool before minor oral surgery.We describe the preoperative application of limited cone beam computerized tomography (CT) using a Dental three-dimensional (3D)-CT as an assessment tool before minor oral surgery. The Dental 3D-CT provided 42.7 mm-high and 30 mm-wide rectangular solid images. This size covered the height of the mandible with standing teeth. Dental 3D-CT clearly demonstrated lesions in the maxillary and mandibular bone. Resorption of the bone due to disease expansion was depicted more clearly on the Dental 3D-CT than on conventional radiographs. Information about lesion location and the relationship between the lesions and their adjacent anatomical structures, such as the mandibular canal and maxillary antrum, was useful for minor oral surgery. Due to its high resolution and low radiation dose, Dental 3D-CT was useful for preoperative examination prior to minor oral surgery.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
8/52. 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) |
9/52. early diagnosis and treatment of supplemental mandibular tooth: report of a case.This report describes a rare case of a supplemental tooth with a morphology similar to a lateral incisor, found in the canine region of the mandible of a 6-year-old male. The purpose of this paper is to report the importance of early diagnosis and treatment during mixed dentition. The treatment was extraction of the primary mandibular left canine soon after the initial diagnosis of the condition to facilitate the spontaneous eruption of the supplemental tooth and his removal. Twenty-nine months after the removal of the supplemental tooth the mandibular left canine was fully erupted into normal position. No complication arose from the presence of this supernumerary and his early diagnosis has been very important for not disrupting the normal erupting or alignment of other teeth.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
10/52. Bilateral maxillary dentigerous cysts: a case report.Dentigerous cysts are benign odontogenic cysts that are associated with the crowns of permanent teeth. They are usually single in occurrence and located in the mandible. Multiple cysts are reported in patients with conditions such as mucopolysaccharidosis and basal cell nevus syndrome. We present the radiologic findings of bilateral impacted maxillary cuspids with dentigerous cysts displacing the maxillary sinuses in a nonsyndromic patient, a condition that, to our knowledge, has not been previously reported.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
