1/11. Rough hypoplastic amelogenesis imperfecta with follicular hyperplasia.

    This report documents a unique case of rough hypoplastic amelogenesis imperfecta with apparent anterior oligodontia and multiple anomalies of the associated mesenchymally derived tissues. Multiple unerupted teeth showed hypercementosis, distorted roots with aberrant dentin formation, and marked follicular hyperplasia. The hyperplastic follicles had a complex histopathologic appearance that recapitulated some features of the WHO-type odontogenic fibroma. The features of these teeth, the nature of the associated follicular lesions, and their relationship to the unerupted teeth are discussed. ( info)

2/11. Generalised hypercementosis: a case report.

    The following case report describes the clinical and radiographical presentation of a female who attended a general dental practice as a new patient. The patient was diagnosed with generalised hypercementosis, possibly attributable to oral neglect. hypercementosis is associated with a number of aetiological factors, which may be local or systemic in nature. It is important that the general dental practitioner is aware of these factors and is able to distinguish presentation due to a local cause from that of a systemic disease process. The aims of this paper are to illustrate an unusual presentation of hypercementosis and to discuss the radiographic differentiation that led to diagnosis. ( info)

3/11. Atypical hypercementosis versus cementoblastoma.

    hypercementosis is a non-neoplastic condition in which excessive cementum is deposited in continuation with the normal radicular cementum. Apart from the idiopathic nature of hypercementosis, this condition is associated with several local and systemic factors. Cementoblastoma is an odontogenic tumour characterized by the proliferation of functional cementoblasts that form a large mass of cementum or cementum-like tissue on the tooth root. Although hypercementosis and cementoblastoma are typical conditions with distinct clinical evolution, atypical cases may challenge their diagnosis. Because cementoblastoma is a neoplasm with unlimited growth potential, the usual treatment is complete surgical resection, whilst conservative treatment is recommended for hypercementosis. An atypical case of hypercementosis with similarities to cementoblastoma is reported and its differential diagnosis is discussed. ( info)

4/11. Progressive, generalized, apical idiopathic root resorption and hypercementosis.

    BACKGROUND: root resorption is a multifactorial process that results in loss of tooth structure. The causes of root resorption may vary, leading to several types of resorptions. Some factors have been identified and may be categorized into physiological resorption, local factors, systemic conditions, and idiopathic resorptions. The objective of this report was to present a case of a 17-year-old white female with progressive, generalized, apical idiopathic root resorption followed up for 34 months. methods: Two panoramic radiographs, 14 and 34 months after initial clinical and radiological examinations, showed the rapid progression of apical root resorption. Two molars, teeth #15 and #16, which had to be extracted, and a bone sample from the distal aspect of tooth #15 were processed for histologic analysis. RESULTS: Two millimeters apical to the cemento-enamel junction, an abrupt increase in the cementum thickness was noted, amounting to 300 and 800 microm in teeth #15 and #16, respectively. The thickening of the cementum layer was due to an accelerated deposition of cellular intrinsic fiber cementum. An unusually high number of mineralization foci were observed in association with acellular extrinsic fiber cementum, and both free and fused cementicles were seen. In contrast to tooth #16, tooth #15 revealed extensive dentin replacement by a bone-like and a cementum-like tissue. Furthermore, ankylosis was demonstrated in tooth #15 and confirmed in the bone sample. CONCLUSIONS: At present, there is no preventive or therapeutic regimen for the type of root resorption seen in this case report. Treatment usually consists of the extraction of teeth with advanced lesions. ( info)

5/11. osteomyelitis of the mandible associated with autosomal dominant osteopetrosis: a case report.

    osteopetrosis is a rare hereditary bone disorder presenting with variable clinical features and is characterized by an increase in bone density. The main clinical findings of the benign-type of osteopetrosis (autosomal dominant) are fractures and osteomyelitis of the mandible, leading to the detection of the disease. We report a case of autosomal dominant osteopetrosis with secondary mandibular osteomyelitis. Clinical and radiological patterns and treatment evaluation were assessed. The patient was referred for evaluation and treatment of an acute abscess in the left side of the face and osteomyelitis of the mandible. Several imaging studies were performed to assess the lesion and the adjacent bone and soft tissue structures. Treatment consisted of intravenous antibiotic therapy, debridement of the necrotic bone and sequestrum, and extra-oral drainage of the abscess, with submandibular access. Healing was uneventful.

6/11. Oculodentodigital syndrome: report of a case.

    The clinical and radiographic changes in a case of oculodentodigital syndrome are presented. The characteristic features of this rare developmental disorder, microphthalmus with microcornea and iris anomalies, hypertelorism, thin nose with hypoplastic alae and anteverted nostrils, syndactyly with camptodactyly and clinodactyly of the fourth and fifth fingers associated with bony anomalies of the middle phalanges of the fifth fingers and toes, were all present. In addition, histological examination of a lateral incisor showed the enamel dysplasia to be due to enamel hypoplasia; the dentine also showed marked hypocalcification. There were widespread pulp denticles and hypercementosis throughout the dentition. Both the patient and his mother had coronoid hypoplasia. ( info)

7/11. Multiple radiopaque masses in the jaws.

    In this report, the less common oral findings occurring in Gardner's syndrome are described, which occurred concurrently with colorectal polyposis. In addition, what clinically appeared as small intestinal polyps, microscopically represented nodular lymphoid hyperplasia, as reported in the literature. review of the literature showed the oral findings reported here are not common and that enzyme assays can help detect polyps at an early stage of this complex syndrome.

8/11. Generalized hypercementosis.

    The case of an elderly female patient with a long-standing history of generalized hypercementosis is described. A thorough review of the literature indicates that this may be one of the most extensive cases of hypercementosis to be reported. Possible etiologic factors--including heredity, systemic disorders, chronic periapical infection, and abnormal occlusal trauma--are discussed. ( info)

9/11. Early hypercementosis and arrested dental eruption: heritable multiple ankylodontia.

    This study describes arrested posterior permanent tooth eruption in association with hypercementosis, reduction of the periodontal ligamental space, and bony ankylosis. The severe dental malocclusion occurred in four members of the same family and it appears to have an autosomal dominant mode of inheritance. ( info)

10/11. hypercementosis--an important clue to Paget disease of the maxilla.

    Paget disease of the maxilla and mandible is not rare. There appears to be a significant correlation between skull involvement in the form of osteoporosis circumscripta and maxillofacial changes. The maxillary component can be of the typical form of Paget disease or be in the form of hypercementosis. The latter change is not well recognized and we present two cases with such involvement.
