Achondroplasia with multiple supplemental supernumerary teeth and multiple talon cusps: A rare case report.

Achondroplasia is the most common cause of dwarfism, which is inherited as an autosomal dominant disorder, caused by genetic mutation in fibroblast growth factor 3, leading to defective maturation of chondrocytes. It is known to be associated with various oral and dental manifestations such as delayed dental development, midfacial hypoplasia and constricted maxilla with a relatively large mandible, resulting in skeletal/dental Class III malocclusion, posterior crossbite, anterior reverse jet and anterior overbite. However, the association of achondroplasia with talon cusp and supernumerary teeth has never been reported in the literature. Wehereby reported a case of achondroplasia associated with such unusual findings. Moreover, all the three variants of talon cusp, i.e., "true talon,""semitalon" and "trace talon" are observed in the present case, which makes it a unique one. Further double talon cusps were noticed in the palatal aspect of maxillary central incisors.

Multifocal Eosinophilic Granuloma of Jaws and Skull with Classical and Unusual Radiographic/Imaging Findings.

Eosinophilic granuloma is basically a disorder of reticuloendothelial system and is one of the variants of langerhans cell histiocytosis. Multifocal eosinophilic granuloma affecting jaws and skull is relatively a rare disorder. We hereby report a case of multifocal eosinophilic granuloma involving mandible, maxilla and several skull bones. The present case has mixture of classical floating teeth appearance and an unusual radiographic/imaging finding of periosteal remodeling, which is rarely seen in adult patients of eosinophilic granuloma and pseudo-multilocular appearance in anterior mandibular region in coronal sections and moth-eaten appearance of skull was appreciated in axial slices of Computed Tomography (CT).

Ellis-van Creveld syndrome with unusual oral and dental findings: A rare clinical entity.

Ellis-van Creveld (EVC) syndrome, a form of skeletal and chondroectodermal dysplasia, is an autosomal recessive disorder characterized by a tetrad of disproportionate dwarfism, postaxial polydactyly, ectodermal dysplasia, and heart defects. In the present article, we hereby present a case of a 13-year-old girl of Indian ethnicity with EVC syndrome with a remarkable number of classical oral and dental features, with unusual findings such as taurodontism and talons cusp. Such dental findings were reported in few cases only. Despite the fact that oral manifestations play an important role in the diagnosis of EVC, only a few detailed reports have been published in the dental literature.

"Osteolipoma of buccal mucosa: Case report and literature review".

UNLABELLED: Osteolipoma affecting oral cavity is indeed rare. We hereby report a case of osteolipoma affecting buccal mucosa. A review of literature of osteolipoma of oral cavity, particularly on radiographic/imaging findings was done. Only 16 cases of Osteolipoma of oral cavity are reported in the literature. The radiographic findings of our case, i.e. multiple dense homogenous radio-opaque structures was reported earlier only in one case [out of 16] of osteolipoma of oral cavity. KEY WORDS: Lipoma, osteolipoma, panoramic radiography, radio-opaque, radiography.

Central mucoepidermoid carcinoma of the maxilla with unusual ground glass appearance and calcifications: A case report.

Mucoepidermoid carcinomas (MECs) arising within the jaws as primary central bony lesions are termed central MECs. Central MECs are extremely rare, comprising 2-3% of all mucoepidermoid carcinomas. We herein report a rare case of central MEC of the maxilla in a 52-year-old male whose plain radiographs showed a "ground glass" pattern and computed tomographic images, a hypodense mass with numerous calcifications. To the best of our knowledge, this is the first report of central MEC showing a "ground glass" appearance.

Radiosensitizers, radioprotectors, and radiation mitigators.

Radiotherapy is regarded as one of the most important therapeutic modality for the treatment of malignant lesions. This field is undergoing rapid advancements in the recent times. With the use of radiosensitizers and radioprotective agents, the course of radiotherapy has improved the sensitization of tumor cells and protection of normal cells, respectively. The aim of this paper was to critically review and analyze the available compounds used as radiosensitizers, radioprotectors, and radiation mitigators. For reviewing, the author used the electronic search for the keywords 'Radiosensitizers', 'Radioprotectors', 'Radiation mitigators' on PubMed for inclusion of previously published articles and further search of reference papers on individual radiosensitizing and radioprotecting agents was done. Radiosensitizers are agents that sensitize the tumor cells to radiation. These compounds apparently promote fixation of the free radicals produced by radiation damage at the molecular level. The mechanism of action is similar to the oxygen effect, in which biochemical reactions in the damaged molecules prevent repair of the cellular radiation damage. Free radicals such as OH + are captured by the electron affinity of the radiosensitizers, rendering the molecules incapable of repair. Radioprotectors are compounds that are designed to reduce the damage in normal tissues caused by radiation. These compounds are often antioxidants and must be present before or at the time of radiation for effectiveness. Other agents, termed mitigators, may be used to minimize toxicity even after radiation has been delivered. This article tries to discuss the various aspects of radiosensitizers, radioprotectors, and radiation mitigators including the newer agents.
