    ABSTRACT: Intramuscular cavernous hemagiomas represent less than 1% of all hemangiomas and consist of benign proliferations of blood vessels. Typical presentation is an enlarging painful soft-tissue mass without cutaneous changes. We report a case of cavernous hemangioma of the buccinator muscle presenting as an asymptomatic unilateral swelling. The rarity of a cavernous hemangioma in such a location and its presentation as a unilateral swelling without cutaneous changes made the case unique. In addition we highlight the MRI features that guided us to arrive at a diagnosis.

    ABSTRACT: Denture-induced hyperplasia is a reactive lesion arising from excessive and chronic mechanical pressure on the vestibular oral mucosa. It has a female predilection and it is mostly seen in the maxilla. The size of the lesion may be as small as a few millimeters to massive lesion involving the entire vestibule. It is usually asymptomatic but sometimes severe inflammation and ulceration can occur. Elimination of the inflammation and excision of the lesion is the treatment of choice. Denture induced hyperplasia in right maxillary buccal vestibule in a middle age old female patient was presented. Surgical excision was done and new denture was fabricated.

    ABSTRACT: Ameloblastic carcinoma is a rare aggressive odontogenic tumour that exhibits malignant histologic features in the primary site or in metastasis. This rare tumour needs immediate attention because of its aggressive and infiltrative nature. However, there are controversies regarding the definitive treatment because of the very few cases in the literature database. Here, we report a case of a 64-year-old male Asian patient who presented with a non-tender exophytic proliferative mass of 3 months duration. It was finally diagnosed as ameloblastic carcinoma and promptly treated surgically with a regular follow-up. Local long-term control and follow-up is imperative in such patient laying emphasis on potential pulmonary metastasis.

    ABSTRACT: The present review article aims at discussing the various trends evolved in forensic dentistry, particularly referring with the usage of radiographs. Since the radiographs are the quick, easy, simple, economical and non-destructive method of obtaining information about age, sex, race of the victim, it is an indispensable aid in identification. With the advancement of newer technologies, more accurate information is obtained for identification as well as in the facial reconstruction of the unknown deceased person. This article gives an overview of different radiographic methodology and characteristics for identification in oral and craniofacial region. To obtain the most reliable outcome in identification it is necessary that one applies most of these techniques repetitively with appropriate knowledge.

    ABSTRACT: Gemination is an anomaly caused by a single tooth germ that attempted to divide during its development, resulting in a bifid crown. They are found more frequently in the primary than in the permanent dentition unilaterally, but bilateral gemination is very rare. It is caused by complex interactions among a variety of genetic and environmental factors. This developmental anomaly may cause clinical problems including esthetic impairment, periodontal problems, caries, and tooth crowding. Here, we report a unique case of bilateral gemination of permanent maxillary central incisors.

    ABSTRACT: Odontomas are benign tumors containing all the components of the odontogenic tissue. Disturbances in tooth eruption are one of the most common complications associated with odontomas. They are generally asymptomatic and are usually seen in second and third decades of life, rarely seen below 10 years of age. Herewith, we report an unusual occurrence of compound odontoma in a 4-year-old child visualized as a swelling of the cortical bone in the anterior maxilla.

    ABSTRACT: Osteoma is a benign slow growing osteogenic lesion, composed of well-differentiated mature bone tissue, characterized by the proliferation of compact or cancellous bone, almost exclusively found in the head and neck region. Central, peripheral and extra skeletal are the three variants of osteoma. Trauma, inflammation, developmental disorders and genetic defects are considered as the etiologic factors. Paranasal sinuses are the favourite locations of peripheral osteoma of the craniofacial region; frontal and ethmoidal sinuses being the common ones. Although, peripheral osteomas are usually benign, innocuous lesions, their size and prominent location on the visible parts of the face makes the surgical intervention necessary. We report case of multiple peripheral osteomas of forehead, without involvement of the frontal sinus, which is a rare variety.

    ABSTRACT: Mucoceles are the common salivary gland disorder which can be present in the oral cavity, appendix, gall bladder, paranasal sinuses or lacrimal sac. Common location for these lesions in the oral cavity is lower lip however, it also presents on other locations like tongue, buccal mucosa, soft palate, retromolar pad and lower labial mucosa. Trauma and lip biting habits are the main cause for these types of lesions. These are painless lesions which can be diagnosed clinically. Copyright: © 2013 Bortoluzzi MC, et al.

    ABSTRACT: Radicular cyst is the most common odontogenic cyst occurring in the jaws. The cyst is commonly found in relation to the maxillary anterior teeth in the third and fifth decade of life. Although multiple radicular cysts are not uncommon in the jaws, bilaterally symmetrical representation of these cysts is rare. Radiographs prior to extraction help in diagnosis of these cysts and thereby prevent further morbidities. We report a case of 16-year-old male patient who presented bilateral radicular cysts symmetrically in the mandible.

    ABSTRACT: To investigate the prevalence of the talon cusps in a sample of Indian dental patients and their distribution among different types of teeth. To determine the presence of other dental anomalies associated with the talon cusps. 2740 out patients (1523 males and 1217 females) attending Oral Medicine department from November 2010 to January 2011 were screened for the presence of talon cusps and were subjected to Intra Oral Peri-apical (IOPA) radiograph to rule out any associated anomalies or peri-apical changes. Talon cusps were detected in 16 out of 2740 patients (person prevalence 0.58%). Thirty one teeth were found to have talon cusp. Maxillary lateral incisors were the most commonly affected teeth (54.8%, 17 teeth), followed by maxillary central incisors and canines (16.12%, 5 teeth).Talon cusp was found in two mandibular central incisors (6.45%) and one each in mandibular second and third molar (3.22% each). Seventeen teeth in 7 patients (54.83%) were found to be associated with anomalies like dens invagination (6 teeth, 19.35%), impacted 13, 23 (6 teeth, 19.35%), partial anodontia (3 teeth, 9.67%), geographic and fissured tongue (2 teeth, 6.45%). Peri-apical granuloma was found in one tooth with talon cusp associated with dens invaginatus. None of the patients were found to be associated with any syndromes. Attention should be paid to the presence of the talon cusp and the associated anomalies. Early diagnosis of the talon cusp can help the clinician in preventing the further complications. Key words:Orthopantomography, atheroma, stroke.

    ABSTRACT: Schwannoma, a benign nerve sheath tumor is relatively rare in occurrence and even rarer in sites, such as jaw bones. There are only 45 reported cases of intraosseous schwannoma of the jaws reported in the literature. We report a rare case of mandibular schwannoma in a 50-year-old Indian male. The clinical features resembled that of a residual cyst, fibro-osseous lesion or an odontogenic tumor/cyst. Radiological differential diagnoses of ameloblastoma or odontogenic keratocyst was made based on the findings of the orthopantomogram. The lesion was examined histopathologically and a final diagnosis of schwannoma arising from the inferior alveolar nerve was made. The aim of this report is to add information to the existing sparse literature on intraosseous schwannomas of the jaw.

    ABSTRACT: Talon cusp is a dental anomaly also known as an eagle's talon. It is an extra cusp on an anterior tooth which arises as a result of evagination on the surface of a crown before calcification has occurred. The exact etiology is unknown. The inci-dence of talon cusp is less than 6%. Commonly involved teeth are maxillary incisors, usually unilateral but in some instanc-es bilateral. The classical radiographical feature of talon cusp is double teeth appearance. The anomaly has been reported to be unusual in the mandibular dentition. This article reports an unusual case of talon cusp of permanent mandibular central incisors.

    ABSTRACT: One of the important factors in the pretreatment evaluation of patients with squamous cell carcinoma is the detection of the presence and extent of bone invasion by the tumor, which is significant for planning the therapy and determining the prognosis. Therefore, a study was undertaken with an objective to compare the accuracy and predictability of an Orthopantamograph (OPG), conventional Computed Tomography (CT), and Single Positron Emission Computed Tomography (SPECT) in the detection of bone invasion in squamous cell carcinoma patients scheduled to undergo surgery. A descriptive study was carried out on 15 patients with clinically and histopathologically diagnosed squamous cell carcinoma. OPG, conventional CT, and SPECT were carried out on all patients. Subsequently, the bone adjacent to the tumor was assessed histopathologically and served as a gold standard. The various imaging modalities were compared with the gold standard. The study revealed that the tumor infiltration into the bone was positive in eight out of fifteen cases and seven were negative for bone invasion. OPG and conventional CT showed the presence of bone invasion in six out of eight cases with a sensitivity of 75% and a specificity of 100%. The positive predictive value for OPG was 100% and the negative predictive value was 78%. SPECT showed the presence of bone invasion in eight out of eight cases with a sensitivity of 100% and a specificity of 14.3%. The positive predictive value for SPECT was 57% and the negative predictive value was 100%. The present study showed that SPECT was highly sensitive, but with a very low specificity due to an increase in false positive values. However, OPG and conventional CT showed an acceptable degree of sensitivity and specificity.

    ABSTRACT: Dens evaginatus (DE) and dens invaginatus (DI) are developmental anomalies that affect the shape of the teeth. Although they have been found singly and in association with other developmental anomalies in the same patient, it is uncommon to observe these two anomalies in the same tooth. There are only a few published cases of concurrent DI and DE in the same tooth. The patient in the case reported here was a 27-year-old man who exhibited a novel combination of DE and DI in permanent maxillary incisors. Early diagnosis of this anomaly is necessary. The clinician then can take particular care when performing prophylactic odontoplasty for the DE, keeping in mind that the associated DI presents an increased risk of early pulpal involvement. This article focuses on the management aspects of DE and DI.

    ABSTRACT: Non-steroidal anti-inflammatory drugs are commonly prescribed in dental practice after minor oral surgical procedures such as tooth extraction. Diclofenac sodium is one of the non-steroidal anti-inflammatory drugs widely used for pain relief in dentistry. Although adverse reactions to these drugs are rare, at times they can cause a life-threatening phenomenon. Stevens-Johnson syndrome is one such potentially lethal adverse drug reaction. Most reported cases of analgesic-induced Stevens-Johnson syndrome were due to oxicams or propionic acid derivatives. There are very few detailed reports of Stevens-Johnson syndrome due to use of diclofenac. We report here a case of Stevens-Johnson syndrome which occurred due to use of diclofenac sodium. The clinical features of this condition and multidisciplinary management of the patient are described in brief.

    ABSTRACT: Field cancerization was first described in 1953 as histologically altered epithelium surrounding tumor samples taken from the upper aerodigestive tract. Since then, the term has been used to describe multiple patches of premalignant disease, a higher than expected prevalence of multiple local second primary tumors and the presence of synchronous distant tumors within the upper aerodigestive tract. We discuss field cancerization with a case report of a 70-year-old male patient.
