    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 cavit

    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

    Comparison of panoramic radiograph with cone-beam computed tomography in assessment of maxillary sinus floor and nasal floor

    Introduction: Panoramic radiograph is frequently prescribed by dentists for implant planning and, hence, accurate assessment of anatomical structures in panoramic radiograph is of utmost importance. Aims: The aim of the present study is to know the accuracy of panoramic radiograph in assessment of relationship between maxillary sinus floor and posterior teeth roots, and the distance from alveolar crest to nasal floor by comparing it with that of cone-beam computed tomographic (CBCT) image. Materials and Methods: Panoramic and CBCT images of 30 patients were analyzed. The topographic relationship of each root of posterior teeth to the maxillary sinus floor was evaluated and classified into three classes. The distance from the peak point on maxillary alveolar crest to nasal floor was measured in panoramic radiograph as well as in CBCT image. All the measurements were made by built-in measurement tools. Results: Class 1 roots in panoramic radiograph showed high agreement (86%) with CBCT image, followed by class 0 (76%). There was a significant difference in the measurements of alveolar bone height (ABH) in the nasal floor region with a P value of 0.018. Conclusion: Panoramic radiograph is reliable in assessment of nasal floor and maxillary sinus, provided position of the patient, distortion, and the inherent magnification factor are taken into consideration

    Aims and Objectives: To assess and create awareness of oral medicine specialty among medical practitioners, and to assess the volume of oral medicine clinical cases that they come across in their routine practice and to whom they refer them to. Materials and Methods: Printed and validated questionnaires were given to a sample of 100 medical practitioners of different specialties personally in and around Tirupati and the results were analyzed. Results: Sixty-nine percent of medical practitioners were not aware of oral medicine specialty and only 31% were aware of it. Frequent incidence of oral manifestation of systemic diseases, occasional incidence of facial and TMJ pain, oral mucosal lesions, and rare incidence of salivary gland disorders were noted in their routine practice. Oral manifestation of systemic diseases and oral mucosal lesions were frequently being referred to a general dentist and not to any specific specialty. TMJ and facial pain were referred to an ENT specialist and salivary gland problems to a general surgeon commonly. Conclusion: It is time to reiterate and spread the awareness among the medical professionals about oral medicine speciality in diagnosis and management of many oral ailments. Proper diagnosis and medical management should be the preferred line of therapy for any ailment

    Reliability of single panoramic radiograph with vertical and horizontal parallax; and intraoral periapical radiograph with Clark′s rule compared to computed tomography/surgical exposure in localization of impacted permanent maxillary canine

    Aim: The aim of the study was to evaluate an accurate, inexpensive and low-radiation conventional radiograph suitable for localization of impacted maxillary permanent canine. Materials and Methods: The study comprised 38 subjects in the age group of 13-50 years of both the genders with 50 impacted canines. Panoramic radiographs (OPGs) (on which Chaushu et al. criteria was applied) and intraoral periapical radiographs (IOPARs) (on which Clark′s rule was applied) of the subjects were made and the accuracy of the above two radiographic techniques were compared with computed tomography (CT) axial sections or with surgical exposure, which was considered as the standard guide for localization of impacted maxillary permanent canine. The data obtained was tabulated and subjected to statistical analysis using the statistical package for SAS software. Results: Localization of impacted maxillary permanent canine tooth done with SLOB (Same Lingual Opposite Buccal)/Clark′s rule technique could predict the bucco-palatal canine impactions in 98% of cases. OPG using differential magnification index could predict location only in 68% of bucco-palatal canine impactions and in 72% based on vertical position. Conclusion: In 68% of cases the bucco-lingual position of the canine in OPG (by magnification index) coincided with the location as per CT/surgical exposure. In 98% of cases localization with SLOB technique coincided with CT/surgical exposure. 72% of cases showed coincidence with vertical position of the canine on OPG with CT/surgical exposure. IOPARs taken with SLOB technique are more accurate than OPGs for localization of impacted permanent maxillary canine teeth
