1/4. 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.

2/4. 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.

3/4. 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.

4/4. Duplication and dilaceration of a crown with hypercementosis of the root following trauma: a case report.

    Trauma to a primary mandibular central incisor resulted in a rare case of dilaceration and duplication of crown with hypercementosis of the root in the permanent successor. This tooth was extracted. This article highlights the consequences of trauma to a primary tooth for a developing permanent successor.
