1/33. A case report of pre-eruptive coronal resorption in a mandibular canine.

    A case of intracoronal resorption in a recently erupted mandibular canine in an 11-year-old girl is presented. Possible aetiology and approaches to treatment of such lesions are discussed.

2/33. Hypodontia, ankylosis and infraocclusion: report of a case restored with a fibre-reinforced ceromeric bridge.

    Retained primary molars without permanent successors often undergo progressive infra-occlusion, without predictable exfoliation. Early prophylactic removal, after assessment of root resorption and adjacent periodontal support loss as well as age of onset, is often indicated. This article describes the joint orthodontic-restorative care of such a case and describes an alternative method of restoration using a fibre-reinforced ceromeric bridge. As well as a conservative preparation and good aesthetics, an overlay restoration provided a fully functional occlusion.

3/33. Infraclusion of primary molars: a review and report of a case.

    The term infraclusion is usually used to define mandibular primary teeth in posterior region that remain below the occlusion level. The degree of infraclusion depends on some factors like deviation below the occlusal plane, and infraclusion of tooth in the alveolar bone. Deficient eruptive force, disturbed metabolism of the periodontal ligament, trauma, local inflammation, deficient local vertical bone growth, disturbance in interaction between normal resorption and hard tissue repair, ankylosis and hereditary components have been given as etiological factors. Complications of infraclused primary molars are tipping of the neighboring teeth, space loss, supraeruption of the antagonists, and dislocations of permanent teeth lying under the primary tooth. In this case report, after reviewing the literature a patient with infraclused mandibular primary second molar has been examined to observe the complications of infraclusion. With an appropriate treatment approach, a proper condition was prepared for the eruption of permanent teeth.

4/33. amelogenesis imperfecta and nephrocalcinosis: a new case of this rare syndrome.

    This article describes a new case of a rare syndrome including enamel agenesis of the primary and permanent dentition, delayed or absent eruption of the permanent dentition, coronal intra-alveolar resorption and gingival enlargement. Renal symptoms include medullary nephrocalcinosis without any apparent cause, and evolution to a renal failure. The early diagnosis provided by the oral symptoms leads to a better renal prognosis. As a consequence, pediatric dentists should be aware of this pathology.

5/33. Radiographic examination of dentigerous cysts in the transitional dentition.

    OBJECTIVES: To examine radiographically the relationship between the deciduous tooth and dentigerous cyst of the permanent successor during the transitional dentition. methods: From a retrospective review of all patients who visited our institution from April 1988 to August 2001, 70 patients under 16 years of age who had histologically confirmed dentigerous cysts that had developed from the central incisor to the second premolar were identified. These 70 patients were investigated using panoramic and periapical radiographs. RESULTS: In most cases (54 cases; 77.1%) the cyst was in the premolar region. Of the 54 premolars with dentigerous cysts, the overlying deciduous tooth had already been lost in 7 cases. Of the 47 remaining premolars with associated deciduous tooth, 35 (74.5%) had bone resorption of the periapical or bifurcation region, or irregular resorption of the associated deciduous tooth. Of the remaining 12 deciduous teeth with no periapical lesions, 9 had been treated with root canal therapy. Thus, 44 of these 47 cases (93.6%) had the possibility of inflammation at the deciduous tooth associated with the dentigerous cyst. Evidence from one case in the present study suggesting the process by which cyst development occurs is also given. CONCLUSION: Inflammatory change at the apex of the deciduous tooth may bring on a dentigerous cyst of the permanent successor.

6/33. Pre-eruptive intracoronal radiolucent defect: a case of a nonprogressive lesion.

    Pre-eruptive intracoronal resorption or defect is an unusual radiolucency located in the dentin, just beneath the dentin-enamel junction of unerupted teeth. The pathogenesis of the phenomenon is unclear. The present case with a radiolucency that has not changed in its dimension over a period of almost 7 years, until tooth eruption, raises a question about the progressive nature of the defect that is defined as "resorption." Resorption may not be the sole explanation for a pre-eruptive intracoronal radiolucent defect. The authors also challenge the hypothesis of "local pressure" as a prime cause for the defect. The authors conclude that, when dealing with pre-eruptive intracoronal radiolucency in permanent teeth, a conservative approach with radiographic follow-up is the recommended treatment if the lesion does not seem to endanger the pulp. Intervention can be postponed until after tooth eruption when treatment does not require surgical intervention.

7/33. Radiolucent lesion of an unerupted mandibular molar.

    A coronal radiolucent lesion of an unerupted and partially developed mandibular second molar was coincidentally found during a routine radiographic orthodontic examination of a generally healthy 9-year old girl. The size of the lesion increased continuously during a 2-year observation period. Histologic examination after extracting the tooth proved the lesion to be an idiopathic external coronal resorption. In a review of the literature, we found no original research on the subject. However, the number of case reports suggests that idiopathic external coronal resorptions are quite common in young patients. Their etiology, however, remains unclear. The case history, histologic findings, differential diagnoses, and possible treatment approaches suggested in the literature are described.

8/33. Treatment of severe pre-eruptive intracoronal resorption of a permanent second molar.

    Pre-eruptive intracoronal resorption is a lesion often located within the dentin, adjacent to the dentin-enamel junction, in the occlusal aspect of the crown. As the lesions resemble caries, they are often referred as "pre-eruptive caries." The purpose of this case report was to describe the diagnosis and treatment of a permanent molar with pre-eruptive intracoronal resorption and to elaborate on possible associated clinical problems. After surgical exposure of the unerupted tooth, the tooth structure in the resorbed area was removed and the tooth was restored with glass-ionomer material. Three months after the treatment, partial pulpotomy had been performed and the restoration was replaced by amalgam. Elaboration on possible associated clinical problems is provided.

9/33. Parry-Romberg syndrome: a report of the dental findings in a child followed up for 9 years.

    INTRODUCTION: The incidence of Parry-Romberg syndrome (PRS) is very rare. CASE REPORT: A case report is presented highlighting the main dental aspects that include delayed eruption, root resorption, dilacerations, and a reduction in the height and width of the ramus and body of the mandible on the affected side.

10/33. Resorption of the crown of an unerupted permanent molar.

    This case report describes an unusual phenomenon where resorption occurred in the crown of an unerupted permanent molar. It was an incidental radiological finding. After eruption the tooth was extracted. Histological examination revealed resorption of enamel and dentine, and partial replacement by calcific material. The possible aetiology of the condition is discussed.
