Dental consultation in patients planned for/undergoing/post radiation therapy for head and neck cancers: A questionnaire-based survey.

Background: Mouth and pharyngeal cancers account for approximately 6% of cancers worldwide. Radiotherapy is one of the means of treatment of head and neck cancer. Consultation with a dental team experienced in caring for patients undergoing treatment for head and neck cancer will improve the quality of life of such patients. Aims and Objectives: To evaluate the attitude of oncologists toward dental consultation to patients planning for/prior to/undergoing/post radiation therapy for head and neck cancers and to evaluate the number of radiation oncologists who encounter oral complaints and consider worth referring to a dentist. Materials and Methods: A questionnaire-based study was carried out following mailing of covering letter and self-administered questionnaire comprising 11 items, to 25 radiation oncology centers selected in India based on convenient sampling. Results: Out of the 25 centers, we received response from 20 centers with 60 completely filled questionnaires. Five centers did not respond for further correspondences. Conclusion: The study indicated a need for awareness and education among radiation oncologists regarding dental consultation in patients planned/undergoing /post radiation therapy for head and neck cancer.

Ultrasonographic evaluation of inflammatory swellings of buccal space.

Objectives : The main objective of the study was a) to differentiate cellulitis and abscess in buccal space region, b) to study the ultrasonographic anatomy of cheek region and c) to investigate the use of ultrasound in the diagnosis of inflammatory swellings of cheek region. Patients and Methods : The study consisted of 25 patients with unilateral buccal space inflammatory swellings of odontogenic origin. The contra lateral side was used as control. Toshiba ultrasonographic device with a linear array transducer (5-8 MHz) was used. The areas of interest were scanned under both transverse and longitudinal sections and were interpreted by a single observer. The clinical diagnosis of cellulitis or abscess was confirmed by the absence or presence of pus respectively both sonographically and by aspiration. Also various anatomical structures present in buccal space were studied. Results : Clinically 23(92%) were diagnosed as buccal space abscess and 2 (8%) were cellulitis. Ultrasonographically and therapeutically 24 (96%) were buccal space abscess and 1 (4%) was cellulits. The sensitivity of clinical criteria over ultrasonographic diagnosis was 96% with a specificity of 100%. Also the cheek thickness in males and females varied from 8.2 to 17.1mm with a mean of 11.6mm±2.1 (SD) and 8.2 mm to 14.2 mm with a mean of 11±1.8 (SD). The subcutaneous tissue appeared moderately echogenic, buccinator - highly echogenic, deep adipose tissue - less echogenic and parotid duct was appreciated as a thin hyperechogenic band crossing the buccinator muscle. Buccal space, masticator space and parotid space were appreciated. Conclusion : This study supports the ultrasonographic method of imaging of orofacial inflammatory swellings with high sensitivity and specificity. This imaging modality can also help in aspiration of pus in different spaces. We have described the ultrasonographic anatomy of the above mentioned spaces which can help a beginner in this field.

An unusual case of non-syndromic occurrence of multiple dental anomalies.

Dental anomalies have been known to occur in humans due to a variety of genetic and environmental factors. Combinations of dental anomalies are known to be associated with specific syndromes. A few cases of multiple dental anomalies have been reported in patients with no generalized abnormalities. This case report describes an unusual occurrence of a combination of dental anomalies in an apparently normal healthy 12-year-old female patient. The dental anomalies in this patient were multiple dens invaginatus, generalized enamel hypoplasia, generalized microdontia, root resorption and multiple periapical lesions, shovel shaped incisors, cup shaped premolars, taurodontism, hypodontia and supernumerary teeth.

Glass embedded in labial mucosa for 20 years.

Foreign bodies may be deposited in the oral cavity either by traumatic injury or iatrogenically. Among the commonly encountered iatrogenic foreign bodies are restorative materials like amalgam, obturation materials, broken instruments, needles, etc. Few reports of glass pieces embedded in the soft tissues of the mouth have been published. We report a case where glass pieces had been lodged in the lower labial mucosa for 20 years, with consequent peripheral reactive bone formation.

A rare presentation of oral pemphigus vulgaris as multiple pustules.

Pemphigus vulgaris is an autoimmune blistering disease affecting the mucous membrane and skin. Ulcers, vesicles, bulla, erosions are the common manifestations of the disease. It is uncommon to find multiple pustular lesions in the oral cavity. Here, we report the first case of multiple pustules involving the lateral borders of tongue, buccal mucosa, hard palate, soft palate, vestibule and the gingiva of a 53 year old male. Histopathologic and Immunofluoroscence study was suggestive of pemphigus vulgaris. The condition improved with systemic corticosteroid along with adjuvant therapy. Key words: pemphigus vulgaris, multiple pustules, immunofluorescence, corticosteroids.
