The diagnosis and confirmation of oral SCC (squamous cell carcinoma) is still dependent on histopathology report in spite of development of radiological investigations. It is, thus important to understand the underlying molecular mechanisms and how the alterations in metabolic pathways effect the tumor development and progression. The simultaneous and comprehensive information about the presence and absence of small molecule metabolites and their relative concentrations has been provided by1 H HR-MAS NMR spectroscopy on tissue specimens...

Nanotechnology is widely used in our day to day life including its use in medicine. Using nanotechnology, it is easy to analyze and manipulate atoms, chemical bonds and molecules present between various compounds. Nanotechnology is used in the dental field as nano dentistry. While choosing the nanoparticle for the use in the field of nano dentistry its chemical, physical, along with the biological aspect of nanostructures are taken into account. Often various atoms or molecules are added to form the functional structure...

Background: The host's answer has an important role in periodontal disease, and the mast cells have a prime role. Such cells seem to be influenced by estrogen deficiency. The objective was to evaluate the mast cells and the expression of metalloproteinase(MMP)-9 in periodontal disease induced in ovariectomized rats. Methods: For that purpose, 36 rats were used; 18 ovariectomized (OVX) and another 18 Sham-operated (SHAM). After 60 days the periodontal disease was induced by a ligature around the first lower right molars (group P)...

Introduction: Scientific literature suggests that human papillomavirus (HPV) infection may be associated with oral squamous cell carcinoma (OSCC). However, knowledge regarding HPV-OSCC link among oral health professionals (OHP) has been insufficient. So, the aim of this study was to assess the knowledge about HPV associated OSCC among OHP working in dental faculties in Malaysia. Methodology: Ethical committee of the University approved this study. A validated, pre-tested questionnaire was sent electronically to 224 OHP...

Background: Patients with limited mouth opening (LMO) often associated with difficult intubation. Retrograde intubation is an alternative technique of establishing definitive airway in these patients when blind nasal intubation fails and fiberoptic bronchoscope is not available. We tested the retrograde intubation through nasal route in patients with LMO less than 2 cm. Materials and methods: The procedure was performed with some modification with regard to retrograde guide on 18 patients requiring maxillofacial surgical procedures to increase mouth opening...

Management of facial asymmetry is one of the arduous and challenging task to accomplish in disciplines of orthodontics and maxillofacial surgery. This article aims to describe various treatment modalities adopted conjointly by the orthodontist and maxillofacial surgeon, taking into consideration the realistic concerns and expectations of the patient. This would help improve treatment outcomes while ensuring overall well-being of the patient.

Facial asymmetry is an individualized characteristic and is commonly observed sub clinically in overall population. However, clinically significant facial asymmetry with associated morphologic, esthetic and stomatognathic problems warrant investigation of the underlying etiology and comprehensive clinical examination in conjunction with imaging studies for diagnosis, localization of asymmetry and treatment planning. The principal aim of this article is to present an invaluable insight into etiopathogenesis, myriad classifications and various systematic diagnostic approaches indispensable for formulation of treatment plan and appropriate management of facial asymmetry...

Purpose: To assess whether concomitant particulate bone grafting makes a difference in the ability to safely orthodontically reposition teeth outside the bony envelope after corticotomy. Material and methods: Retrospective analysis of patients who underwent corticotomy as part of their orthodontic therapy for treatment of severe crowding. Patients were divided as: a) Group 1: corticotomy with bone grafting, and, b) Group 2: corticotomy without bone grafting. CT scan examinations were performed before and at the end of the treatment...

A 68-year-old Caucasian gentleman presented with a 6-month history of a left sided Level I/II neck swelling involving the floor of mouth. MRI revealed a large cystic lesion and histology confirmed a diagnosis of primary papillary cystadenocarcinoma of the sublingual gland. Papillary cystadenocarcinoma was first described in 1991 by the World Health Organisation [WHO], and is a rare malignant neoplasm characterised by cysts and papillary endo-cystic projections. Papillary cystadenocarcinoma arising from the sublingual glands is extremely rare and has the potential to metastasise to cervical lymph nodes...

The Inflammatory myofibroblastic tumor (IMT) is a heterogeneous group of rare lesions consisting predominantly of inflammatory cells and myofibroblastic spindle cells. Head and neck IMTs account for 14 to 18% of extra-pulmonary IMTs [lungs being the most commonly affected regions]. On account of its ambiguous clinical presentation, an IMT needs to be differentiated from other infectious, granulomatous, autoimmune and neoplastic lesions on the basis of histopathologic findings and immunohistochemical analysis...

Nuzhat Husain, Azfar Neyaz
High-risk human papillomavirus (HR-HPV) is a causative agent for an increasing subset of oropharyngeal squamous cell carcinoma. HPV 16 accounts for 90% of cases. The chance for malignant transformation due to infection with high-risk HPV is proportional to the expression of the viral oncogene products E6 and E7, which inactivate p53 and retinoblastoma (Rb) tumor suppressor functions. P16 is a surrogate marker of HPV associated HNSCC and 2+/3+ expression in more than 75% cells is diagnostic. Molecular demonstration of integrated virus by in situ hybridization is specific but has low sensitivity...
