1/55. Multiple idiopathic resorption in the primary dentition: review of the literature and case report.

    Resorption of primary teeth is a normal physiologic process, except when it occurs prematurely. Resorption of permanent teeth is considered abnormal, and multiple etiologic factors have been implicated. A significant number of cases are represented by idiopathic resorption. Multiple idiopathic root resorption stands as a separate physiologic entity that has been described as affecting the entire permanent dentition. Multiple idiopathic resorption of primary teeth has not been previously reported. A case is described and a differential diagnosis is provided. The specific radiographic diagnostic criteria for this condition affecting the primary dentition are outlined. ( info)

2/55. 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. ( info)

3/55. Development and treatment of retrograde peri-implantitis involving a site with a history of failed endodontic and apicoectomy procedures: a series of reports.

    Osseointegrated implants provide predictable restorative support for crowns, restorations, prosthesis abutments, and removable dentures. Their widespread use in recent years has produced different types of complications. Retrograde peri-implantitis, a lesion occurring at the periapical area of an osseointegrated implant, has recently been described. This paper presents a series of reports describing the occurrence and management of retrograde peri-implantitis involving implants replacing teeth with histories of failed endodontic and apicoectomy procedures.

4/55. Radiographic findings in 224Ra-caused dental resorptions.

    Dental resorptions as a delayed effect of thorium X (224Ra) were observed in four patients. The radiographic findings showed distinct and representative patterns. Apparently, the observed changes are typical for delayed alterations related to 224Ra-specific disturbances in the alveolar process. Degenerative and inflammatory reactions may also be involved in the pathogenesis. ( info)

5/55. External cervical resorption associated with localized gingival overgrowth.

    AIM: To describe the presentation and management of an unusual lesion of external cervical resorption. SUMMARY: The salient features of this unusual presentation of the external cervical resorption with localized gingival overgrowth, and the resorption located almost wholly on the labial aspect of a maxillary incisor crown are described. Extensive loss of enamel had occurred. The management and possible aetiology of the resorptive lesion are discussed. KEY learning POINTS: Localized gingival overgrowth can be associated with external cervical resorption.The cervical resorption does not necessarily indicate pulp canal infection and the need for root-canal treatment.

6/55. Unusual fracture of a mandibular second premolar: a case report.

    Root fractures of posterior teeth, which are defined as fractures involving cementum, dentin, and pulp, are relatively uncommon among dental traumas. This study describes an unusual horizontal fracture of a mandibular second premolar. The tooth was asymptomatic and the fracture unnoticed until the crown broke off completely. The patient had no recollection of a causative event nor was there any evidence of previous physical trauma. The tooth was extracted, embedded in resin, sliced, and examined with different light microscopes. It was concluded that the tooth had been damaged previously but not to the extent that the pulp was seriously damaged. Resorption over a period of time eventually caused the final fracture. ( info)

7/55. amelogenesis imperfecta: a scanning electron microscopic and histopathologic study.

    amelogenesis imperfecta (AI) is a hereditary defect in enamel formation affecting both primary and permanent dentition. Scanning electron microscopic investigation is one of the most effective methods in diagnosing and identifying the type of amelogenesis imperfecta. The aim of this study was to investigate the ultrastructure of different types of amelogenesis imperfecta enamel. The primary teeth of three children with AI aged 4, 10 and 11-years-old were studied by scanning electron microscopy and irregular enamel, irregularities in enamel crystallites, hypoplastic areas on the enamel surface were seen. Histopathological evaluation revealed predentin areas with irregular canaliculi between normal dentin and internal resorption areas in the pulp tissue. Conclusively, in amelogenesis imperfecta, enamel tissue is mostly affected besides minor defects in dentinal and pulpal tissue. ( info)

8/55. transplantation of a lower bicuspid after traumatic loss of three upper incisors.

    BACKGROUND: Prosthodontic and orthodontic procedures have been described for the treatment of patients with traumatic loss of teeth. PATIENT AND methods: Both upper central incisors and the upper right lateral incisor had to be extracted in an 8-year-old patient after failure of conservative procedures following a sports accident. The patient was treated on a temporary basis with a space retainer as a substitute for the teeth. Definitive therapy was carried out by transplanting a lower bicuspid germ into the upper arch with subsequent orthodontic gap closure. RESULTS: 8 years after the intervention, the transplanted tooth is still in place. The patient is fully rehabilitated both functionally and esthetically with no discomfort. CONCLUSIONS: The transplantation of bicuspid germs in conjunction with orthodontic gap closure is a valuable alternative to prosthodontic treatment, particularly in the case of loss or aplasia of several teeth.

9/55. Aneurysmal bone cyst of the maxilla--an association with tooth resorption.

    The aneurysmal bone cyst is an uncommon lesion of the jaws. Cases involving the maxilla have been reported infrequently. Despite uncertainty as to the aetiology of the aneurysmal bone cyst, it is regarded as a benign lesion. Conservative surgical treatment with regular postoperative follow-up is recommended. The case described here presented with tooth mobility resulting from extensive root resorption. A review of the literature reveals that significant root resorption is not a commonly reported feature of aneurysmal bone cysts. For the present case we interpret the evidence as supporting a diagnosis of idiopathic root resorption complicated by the formation of a aneurysmal bone cyst. ( info)

10/55. Clinical complications associated with supernumerary teeth: report of two cases.

    The presence of supernumerary teeth can interfere in normal occlusal development. The pediatric dentist should diagnose them as soon as possible, as most of the time they are asymptomatic. The objective of this paper is to show the presence of that dental anomaly in two pediatric patients, as well as the associated clinical complications with treatment. ( info)
