TR Saraswathi, K Ranganathan, S Shanmugam, R Sowmya, Prem Deepa Narasimhan, R Gunaseelan
July-September 2006, 17(3):121-5
DOI:10.4103/0970-9290.29877  PMID:17176828
BACKGROUND: Smoking, drinking and chewing tobacco product, common habits in India have been positively associated with oral lesions. No study has been conducted in this part of Tamilnadu regarding the prevalence of oral lesions in relation to habits. METHODS: A hospital based cross-sectional study was carried out at Ragas Dental College, Chennai. Already existing data of two thousand and seventeen consecutive patients from sub-urban areas of Chennai, who attended the outpatient department, at Ragas Dental College, for dental complaints during a period of three months in 2004, who underwent oral examination and interviewer based questionnaire was used. RESULTS: Oral soft tissue lesions were found in 4.1% of the study subjects. The prevalence of leukoplakia, OSF and oral lichen planus was 0.59%, 0.55%, and 0.15% respectively. The prevalence of smoking, drinking alcoholic beverages and chewing was 15.02%, 8.78% and 6.99% respectively. Smoking and chewing were significant predictors of leukoplakia in this population. DISCUSSION: The prevalence of leukoplakia, OSF and oral lichen planus in our study population is similar to those found in other populations. The prevalence of consumption of alcoholic beverages in our study population was higher when compared to the Indian National Sample Survey study. However the prevalence of smoking and chewing was found to be lower. Smokers were more likely to develop smoker's melanosis compared to other lesions. Among those who consumed alcoholic beverages alone, the prevalence of leukoplakia was higher compared to other lesions. OSF was the most prevalent lesion among those who chewed panmasala or gutkha or betel quid with or without tobacco.

Florid cemento-osseous dysplasia : Review and report of two cases.
M Mangala, DN Ramesh, PS Surekha, P Santosh
July-September 2006, 17(3):131-4
DOI:10.4103/0970-9290.29875  PMID:17176830
Only three Indian patients of florid cemento-osseous dysplasia have been reported (less than 2%), according to the review of recent literature (2003). This makes the occurrence of FCOD a relatively rare phenomenon. The age group may vary from 19-76 years and typically presents in the fourth and fifth decade. In most of the cases, patients do not have family history of the disease. We report two cases showing classic radiologic features. The diagnosis of our cases were made radiographically.

ORIGINAL RESEARCH
Assessment of the efficacy of an indigeniously developed pulse oximeter dental sensor holder for pulp vitality testing.
V Gopi Krishna, D Kandaswamy, T Gupta
July-September 2006, 17(3):111-3
DOI:10.4103/0970-9290.29880  PMID:17176825
Current routine methods of assessment of pulp vitality rely on stimulation of nerve fibres and give no direct indication of blood flow within the pulp. Pulse oximeter is a proven, atraumatic method of measuring vascular status, by evaluating oxygen saturation. This study explores the use of customized dental pulse oximeter sensor holder to assess pulpal vascular oxygen saturation in permanent teeth. Pulse oximeter readily differentiated between known vital and nonvital teeth. Vital teeth consistently provided oxygen saturation values that were lower than the values recorded on the patient's fingers. Pulse oximeter is an accurate, atraumatic clinical alternative to the present electrical and thermal methods of assessing pulp vitality in teeth.

CASE REPORT
Mucormycosis presenting as palatal perforation.
S Jayachandran, C Krithika
July-September 2006, 17(3):139-42
DOI:10.4103/0970-9290.29873  PMID:17176832
Mucormycosis is an opportunistic fungal infection that is caused by normally saprobic organism of the class Zygomycetes. The main form of mucormycosis are pulmonary and rhinocerebral. Rhinocerebral mycormycosis typically starts in the maxillary antrum, particularly in poorly controlled diabetics. Invasion of surrounding tissue can cause necrotizing ulceration of palate with a blackish slough and exposure of bone. A case of mucormycosis presenting as palatal performation is discussed in this article.

DOI:10.4103/0970-9290.29874  PMID:17176831
Solitary intraosseous neurofibroma is a rare benign non-odontogenic tumor. Although neurofibromas occur predominantly as a feature of neurofibromatosis affecting the soft tissue, a few cases of solitary intraosseous neurofibromas of the jaw have been reported. We herewith report a case of solitary intraosseous neurofibroma of mandible in a middle-aged woman with a discussion on its clinical, radiological, and histopathological presentation along with review of cases.

Evaluation of salivary nitric oxide levels in oral mucosal diseases : A controlled clinical trial.
M Sunitha, S Shanmugam
July-September 2006, 17(3):117-20
DOI:10.4103/0970-9290.29878  PMID:17176827
Lichen planus is a common dermatologic disease to manifest in the oral cavity. Recurrent aphthous ulcers are the most common ulcers of the oral cavity causing discomfort to the patients. These two diseases have different clinical manifestations which require appropriate treatment after correct diagnosis. Though numerous etiological factors have been proposed for these diseases, their true etio-pathogenesis is not yet established and therefore all therapies are palliative and none is effective universally. In light of this, the role of nitric oxide as a mediator in the etio-pathogenesis of these diseases was considered. The present study was undertaken to note the salivary nitric oxide levels as measured through its product nitrite in oral mucosal diseases like lichen planus and recurrent aphthous ulcers and also to ascertain whether salivary nitric oxide level has a role to play as a pathophysiological mediator in these diseases

SM Sarah, S Tamilselvan, S Kamatchiammal, R Suresh
July-September 2006, 17(3):114-6
DOI:10.4103/0970-9290.29879  PMID:17176826
Periodontal disease is the major cause of adult tooth loss and is commonly characterized by a chronic inflammation caused by infection by oral bacteria. Members of Toll-like receptor (TLR) family recognize conserved microbial structures, such as bacterial lipopolysaccharides, and activate signaling pathways that result in immune responses against microbial infections. The aim of the present study was to assess the mRNA expression of TLR-2 and TLR-4 in gingivitis and chronic periodontitis. Gingival tissue samples were collected from patients with chronic periodontitis, gingivitis, and healthy controls. Total RNA was extracted and RT-PCR was done for TLR-2 and TLR-4. The results showed that TLR-2 was significantly increased in gingivitis compared to TLR-4 expression and decreased in chronic periodontitis.

TR Saraswathi, T Sheeba, S Nalinkumar, K Ranganathan
July-September 2006, 17(3):104-10
DOI:10.4103/0970-9290.29881  PMID:17176824
BACKGROUND: Experimental studies have shown arecanut to be a cytotoxic substance with mutagenic and carcinogenic potential. OBJECTIVE: The present study was undertaken to evaluate the effect of glutathione on arecanut treated human buccal fibroblast culture and its potential as a chemopreventive agent. MATERIALS AND METHODS: Fibroblast culture was done in Dulbecco's Modified Eagle's Medium MEM) supplemented with 10% Fetal Calf Serum (FCS) and antibiotic at 370C degrees in an atmosphere of 5% carbon di-oxide and 95% air. The fibroblast cells were subjected to different concentrations of aqueous extracts of raw and boiled arecanut. Fibroblasts were plated in two 24-well culture plates and in each plate, cells were dividt,ednto 2 groups; 600gg microml of reduced glutathione was added to the first group of cells; subsequently, aqueous extracts of raw and boiled arecanut at least and highest concentrations i.e., 20j. microml and 100lg microml were added to the first group of cells in the respective plates whereas the second group served as a control. The morphological alterations and cell survival were assayed at 24, 48, 72, and 96 hours. Results Morphologically, the initial (10 hours) attached fibroblast cells were converted from spheroidal shape towards hexagonal and finally to a fully extended spindle shaped configuration. The three morphological types of fibroblasts at 48 hours were F-I, F-II and F-III. Aqueous extract of raw arecanut exhibited significant cytotoxicity (p < .0 001) at all time periods studied, when compared against the control values of untreated fibroblasts. Addition of reduced glutathione to cultures showed a significant (p < 0. 001) reduction in cytotoxicity, as indicated by higher optical density values and morphological reversion to the spindle-shaped configuration. CoCONCLUSION:Addition of glutathione reduced the cytotoxic and morphological alterations of the fibroblasts treated with aqueous extracts of both raw and boiled arecanut.
