Abstract
AIM To investigate and record the palatal changes in individuals habituated to reverse chutta smoking in rural coastal Andhra population. MATERIALS AND METHODS Sixty individuals out of whom 47 females and 13 males habituated to reverse smoking with no other tobacco and alcohol habits and no other systemic disturbances were selected. The palatal changes were recorded by six examiners. Database were searched for the following terms "reverse smokers," "nicotina palatini" and "palatal lesions." RESULTS The mean and percentage prevalence of the each lesion recorded and agreed by six examiners among 60 subjects showed presence of 87.77% hyperpigmented areas, 64.44% depigmented areas, 51.66% excrescences, 32.22% potentially malignant lesions and 9.72% frank ulcerations. CONCLUSION Reverse smoking is an endemic tobacco habit still practiced in the coastal rural Andhra Pradesh. It is a well-established and socially acceptable habit among adult females. The changes recorded clinically shows characteristic features that are unique among this population group.

Abstract
Objectives: Oral cancer ranks third among all cancers in the Indian population. Human papilloma virus (HPV) plays a significant role in oral carcinogenesis. Population-based subtype variations are present in the HPV prevalence. This study gives an emphasis on the parameters to be considered in formalin fixed paraffin embedded tissues for polymerase chain reaction (PCR)-based research work. Materials and Methods: Cross-sectional study on archival paraffin-embedded tissue samples of oral squamous cell carcinoma (OSCC), epithelial dysplasia, and normal oral mucosa surrounding impacted tooth was amplified by PCR for the E6 gene of HPV type 16 and E1 gene of HPV type 18. Results: HPV 18 was positive in three OSCC cases. There was no statistically significant association of the positivity of HPV with the age, gender or habit. The HPV positive patients had a tobacco habit and were of a younger age group. Conclusion: The presence of HPV in carcinomatous tissue highlights the possible role of HPV in carcinogenesis and archival paraffin embedded tissue specimen can be used for this analysis. Recent studies on genomic analyses have highlighted that the HPV positive tumors are a separate subgroup based on genomic sequencing. The results of a larger retrospective study will help further in our understanding of the role of HPV in carcinogenesis, this study could form the baseline for such follow-up studies.

Abstract
Aim: The aim of this study is to identify and evaluate Langerhans cell (LC) in lichen planus (LP), lichenoid mucositis (LM) and normal mucosa (NM) using CD1a monoclonal antibody immunohistochemically. Materials and Methods: A total of 15 cases of oral lichen planus and 15 cases of LM were selected based on clinical examination and confirmed by histopathological analysis. The biopsies from the 10 patients were taken from normal buccal mucosa as control. Paraffin blocks of tissue were made, which are used for routine hematoxylin and eosin staining and immunohistochemical staining using biotin streptavidin methods (CD1a monoclonal antibody). Analysis of CD1a expression was performed by evaluating the labeling index (LI) for each slide. Results: The mean CD1a LI for LP was significantly higher than that of LM and NM in the basal and supra basal layer. The mean CD1a positive cells in the connective tissues for LP were higher than that of LM and NM. Conclusion: This study clearly demonstrates a statistically significant increase in number of LC in LP than in LM, indicating the possible different immunopathogenic mechanisms.

Abstract
INTRODUCTION Candidal species colonizes the oral cavities of healthy individuals without dentures and also of denture wearers. Soft liners and tissue conditioning materials have been found to support the growth of Candida albicans which may predispose to lesions. The most important and common candidal species are C. albicans, C. tropicalis, and C. glabrata. C albicans is usually isolated from both the fitting surface of the denture and the denture-bearing mucosa of the affected patients. The aim of this study was to isolate, quantify, and speciate candidal species in non-denture wearers (controls) and denture wearers (study group) by the oral rinse technique. Isolation was done using Sabouraud dextrose agar (SDA). Speciation was done using conventional methods like the germ tube test, carbohydrate fermentation test, urease test, as well as the CHROMagar method. AIMS AND OBJECTIVE 1) To assess the prevalence of Candida in non-denture wearers and in denture wearers by oral rinse technique, with isolation on SDA; 2) to speciate and quantify Candida in non-denture wearers and denture wearers by using conventional methods (germ tube test, carbohydrate fermentation test, urease test) and the CHROMagar method; 3) to assess the influence of smoking and diabetes on candidal species among the denture wearers; and 4) to assess the sensitivity and specificity of SDA and CHRO Magar. MATERIALS AND METHODS Salivary samples for Candida evaluation were collected from the subjects in sterile sample containers, using the oral rinse technique. RESULTS C glabrata was the most commonly found species among denture wearers and non-denture wearers both by conventional and CHROMagar methods. In males, C. albicans was the predominant species, whereas C. glabrata was the predominant species in females. Candidal colonization was higher in denture wearers compared to non-denture wearers, especially among females. The CHROMagar method was more rapid compared to conventional methods. In the present study, CHROMagar Candida showed 100% specificity and 100% sensitivity when compared to SDA and conventional methods.

Abstract
Gingival fibromatosis is characterized by fibrotic enlargement of the gingiva that can occur as inherited or sporadic form. Inherited form can be an isolated trait or as a component of a syndrome. This article reports a 35 year old male patient affected by gingival fibromatosis associated with hemiosseous hyperplasia of mandible, maxilla, and zygoma on the right side, viral papillomatosis of maxillary anterior gingiva, fissured tongue and congenitally missing anterior teeth. The patient was subjected to phase I and phase II periodontal therapy. There was no evidence of recurrence of the enlargement after one year but the papillomatosis recurred. Gingival fibromatosis has been reported to be associated with various other abnormalities but not with those described in our case. This observation raises the possibility that the coexistence of these entities in our case may represent a new syndrome.

Abstract
Most physical injuries resulting from abuse or violence are found on the head and neck areas that are clearly visible to the dental team during examination. Given that dental professionals routinely assess the head, face, and neck of patients, they are in a unique position to identify the signs of abuse and neglect. Involvement of a dentist in the protection team may be beneficial and can lead to early intervention. This article brings to light the importance of questioning and physical examination and the role of a dentist in identifying abuse, assault, and accident.

Abstract
OBJECTIVE The aim of the study was to investigate differences in the palatal rugae patterns in males and females of a cross-sectional hospital-based coastal Andhra population and application of discriminant function analysis in sex identification. MATERIALS AND METHODS One hundred pre-orthodontic plaster casts, equally distributed between males and females belonging to an age range of 15-30 years, were examined for different rugae patterns. Thomas classification was adopted for analysis. Association between rugae patterns and sexual dimorphism were tested using Unpaired t test, Chi square test and discriminant function analysis developed using SAS package. RESULTS Difference in unification pattern among males and females was found to be statistically significant. The total number of the rugae was not statistically significant between the sexes. Association between rugae length and shape with sex determination was computed using discriminant analysis which enabled sex differentiation in this population with an accuracy of 78%. CONCLUSION Palatal rugae revealed a specific pattern in unification among males and females of the coastal Andhra population. Discriminant function analysis enabled sex determination of individuals. However, these interpretations were precluded by the small sample size and further research work on larger samples and use of different classification systems is required to validate its use in forensic science.

Abstract
OBJECTIVES Angiogenesis is a complex event mediated by angiogenic factors released from cancer cells and immune cells. It has been reported to be associated with progression, aggressiveness and metastases of various malignant tumors including oral squamous cell carcinoma (OSCC). Similarly, mast cells have also been reported to play a role in tumor progression and metastases by promoting angiogenesis. The present study aims at comparison of microvascular density (MVD) and mast cell density (MCD) in normal oral mucosa (NM) and among various grades of OSCC. MATERIALS AND METHODS MVD was assessed immunohistochemically using anti-Factor VIII related von Willebrand factor, and MCD using anti-mast cell tryptase in a study sample of 30 cases of OSCC and 10 cases of clinically normal oral mucosa. RESULTS The mast cells in normal oral mucosa and oral squamous cell carcinoma strongly expressed mast cell tryptase. The density of mast cells and micro vessels were significantly higher in OSCC compared to normal oral mucosa. The MCD and MVD were higher in moderately differentiated OSCC than in well differentiated OSCC ( P > 0.05) and normal oral mucosa ( P < 0.05). Pearson's correlation revealed a positive correlation between MCD and MVD ( r=0.33; P=0.077). CONCLUSION These findings indicate that mast cells may play a role in up regulation of tumor angiogenesis in OSCC probably through mast cell tryptase.

Abstract
In oral cavity, the spectrum of diseases due to genetic alterations ranges from developmental disturbances of teeth to the pre-cancerous and cancerous lesions. Of late, significant progress has been made in the molecular analysis of tumors. With molecular genetic testing emerging as diagnostic, prognostic, and therapeutic approach, a review of genetic alterations ranging from the development of oro-facial structures to the tumors in the head and neck region are addressed in this article. The functional regulatory aspect of genes in relation to oro-facial structures are discussed separately, i.e., in relation to tooth genesis, tooth agenesis (non-syndromic, syndromic), tooth structural alterations, syndromic oro-facial defects, bone diseases, skin diseases (genodermatoses), and malignant tumors. In this literature, various genes involved in the development of the oro-facial structures and tooth in particular are discussed. The genetic basis of disorders in the tooth development (agenesis, hypodontia), tooth structural defects like amelogenesis imperfecta (AI), dentinogenesis imperfecta (DI), and oro-facial structural alterations (various syndromes) are explained.

Abstract
Rhinosporidiosis is a benign chronic granulomatous infection caused by Rhinosporidium seeberi. Rhinosporidiosis is endemic in south Asia, notably in southern India and Sri Lanka. Majority of the cases have been reported to occur in upper respiratory sites, notably anterior nares, nasal cavity, nasopharynx, larynx and soft palate. Only two rare cases of involvement of parotid duct, have been reported in literature. Hence, this case will probably be the third to be reported.

Abstract
This study evaluates the usefulness of acrylic dentures as the source of DNA for forensic analysis. Thirty-eight samples (21 males and 17 females) were collected and stored for different time periods. The epithelial cells adhered to the dentures were retrieved and the genomic DNA was extracted. All the samples yielded sufficient amount of DNA for analysis irrespective of the storage time. Gender determination was done by amplification of the sex determining region on the Y chromosome (SRY) using real-time polymerase chain reaction with 100% accuracy, within minimal time. With this study, we conclude that saliva-stained acrylic dentures can act as a source of forensic DNA and co-amplification of SRY gene with other routine sex typing markers will give unambiguous gender identification.

Abstract
OBJECTIVE Cleidocranial dysostosis (CCD) is a skeletal disorder associated with dental anomalies such as failure or delayed eruption of permanent teeth and multiple impacted supernumerary or permanent teeth. Absence of cellular cementum at the root apex is presumed to be one of the factors for failure or delayed eruption. The aim of this study was to analyze the root cementum of supernumerary(S) and permanent teeth (P) of a CCD patient and to compare the findings with those of normal individuals with special emphasis on delayed eruption. MATERIALS AND METHODS Ground sections of 12 extracted teeth (9S + 3P) of a CCD patient and 12 teeth of normal individuals (5S + 7P) were taken for the study. The sections were longitudinal and 50 microm thick. Root characteristics were recorded with the aid of a light microscope. RESULTS The absence of apical cellular cementum, increased root resorption and increased percentage of the gap type of cemento-enamel (C-E) junctions were significant findings noted both in the supernumerary and permanent teeth of the CCD patient. CONCLUSION The presumption of cellular cementum is essential for tooth eruption is not supported by the findings of the present study. Delayed exception could be attributed to various other factors like mechanical obstruction, reduced serum alkaline phosphatase levels etc. Also, the significance of the increased percentage of the gap type of C-E junctions and its role in tooth eruption has to be further evaluated.

Abstract
Odontogenic myxoma (OM) is a rare and locally invasive benign neoplasm found exclusively in the jaws. OM commonly occurs in the second and third decade, and the mandible is involved more commonly than the maxilla. The lesion often grows without symptoms and presents as a painless swelling. The radiographic features are variable, and the diagnosis is therefore not easy. A case of OM of the maxilla with unusual radiographic and histologic features is described in a 30-year-old male. A panoramic radiograph revealed a well-demarcated, multilocular radiolucent lesion with 'tennis racket' appearance involving maxillary antrum. The histopathology showed loosely arranged spindle-shaped stellate cells and few areas of inactive odontogenic epithelium in a mucoid intercellular substance.

Abstract
BACKGROUND Oral submucous fibrosis (OSF) is a precancerous condition associated with the use of areca nut in various forms. There are very few reports to correlate the clinical stage to histopathological grading in OSF. MATERIALS AND METHODS A hospital-based study was conducted on 75 OSF cases who visited our hospital in Chennai from 2000-2003. A detailed history of each patient was recorded along with a clinical examination. Biopsy was performed for histopathological correlation. Clinical stage of the disease in terms of the ability to open one's mouth was correlated with histopathological grading. RESULTS The male to female ratio of OSF cases was 6:1. All forms of areca nut products were associated with OSF. Chewing of paanmasala was associated with early presentation of OSF as compared to chewing of the betel nut. Out of 57 cases, which were in clinical stage II, 91.2% had histological grading of I and II in equal proportions and 8.8% had histological grade III. Out of 13 cases that showed a clinical stage of III, 52% showed a histological grade of II, 40% grade III and 8% grade I. CONCLUSION In the present study, there was no direct correlation between clinical stages and histopathological grading. The possibility of difference in the severity and extent of fibrosis in different regions of the oral mucosa and involved muscles were considered as contributory factors for this variation.

Abstract
BACKGROUND The advent of highly active antiretroviral therapy (HAART) has changed the scenario of human immunodeficiency virus (HIV) infection. HIV patients in India have now access to generic HAART and this is the first report describing oral lesions in patients on HAART from our country. METHODS Oral lesions were studied in HIV seropositive patients (n = 50 on HAART and n = 50 not on HAART) attending a tertiary HIV referral care centre in India and patients on HAART were followed up. RESULTS There was a difference in the occurrence of oral candidiasis (OC) between HAART and non-HAART participants (8%, 24%; P < 0.05). Pseudomembranous candidiasis was 4% and 18% in HAART and non-HAART groups respectively (P < 0.05). In patients with CD4 count <or=200, OC was 5.6% in the HAART group and 39.1% in the non-HAART group (P < 0.05). Among patients with CD4 count >200, pigmentation was 43.8% in the HAART group and 14.8% in the non-HAART group (P < 0.05). CONCLUSION The prevalence of OC in patients who had access to HAART was less when compared with those who did not have access to HAART.

Abstract
A potential approach to the treatment of genetic disorders is gene therapy. The goal of gene therapy is to introduce therapeutic genetic material into the target cell to exert the intended therapeutic effect. Gene therapy has already shown promising results for the treatment of monogenic disorders such as severe combined immunodeficiency and haemophilia. Now the procedure has been extended to the level of treating malignant conditions such as cancer of the lungs, breast, colon etc. The prevalence of tumours of the larynx and oral cavity has increased in both developed and developing countries. This increase underscores the need for a novel therapeutic modality that would decrease or completely terminate the proliferation of malignant cells. This review highlights various types of gene therapy procedures with respect to oral squamous cell carcinoma.

Abstract
Oral submucous fibrosis (OSF) is a common pre-malignant condition of the mouth in arecanut chewers in Indian subcontinent. It is characterized by restriction in opening of the mouth, tongue protrusion, and cheek flexibility. Reports of muscle changes in OSF, using light microscopy are few. Incisional biopsy sections of thirty OSF patients were stained with Masson's Trichrome stain, to study the fibrosis involving the muscle. Wide spectrum of changes were observed where fibrosis was being evident sub-epithelially, not extending in to the muscle to cases where only a few remnants of muscle fibers were seen and the missing muscle bundle area being replaced by fibrous tissue. The probable mechanism by which these changes occur is discussed.

Abstract
BACKGROUND Resting whole mouth salivary flow rate (SFR) and pH play a significant role in pathogenesis of various oral diseases and conditions. AIM To observe the effect of habitual use of arecanut and various arecanut containing products (AN) on SFR and pH. DESIGN Cross sectional. SETTING Outpatient Department of Dental College. PARTICIPANTS AN chewers and non-chewers attending Dental college. MEASUREMENTS SFR and pH. VARIABLES Type, frequency, duration and exposure time of AN, Smoking and Alcohol habit. MATERIALS AND METHODS Subjects study was divided into chewers (n=110) and non- chewers (n=50). The SFR (expressed in mL/10min) and pH measured. RESULTS The difference between the mean SFR for chewers and non-chewers was not statistically significant. The difference between mean pH of chewers and non-chewers was statistically significant. (P=0.02). Difference in pH was statistically significant among the different types of AN chewers (P=0.024). With chewing raw AN, an increase in frequency and exposure time increased SFR and pH respectively. In processed AN chewers, increase in duration and frequency of consumption increased SFR and decreased pH respectively. For chewers with betel quid with tobacco, increase in duration was significantly associated with decrease in salivary pH. CONCLUSION SFR and pH are altered in AN chewers, rendering the oral mucosa vulnerable to the toxic effects of AN.

Abstract
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. Co CONCLUSION Addition of glutathione reduced the cytotoxic and morphological alterations of the fibroblasts treated with aqueous extracts of both raw and boiled arecanut.

Abstract
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.

Abstract
Witkop tooth and nail syndrome is an autosomal dominant ectodermal dysplasia characterized by hypodontia and nail dysplasia. Mutations in MSX-1 have been identified as being involved in the syndrome. Mandibular incisors, secondary molars and maxillary canines are the most frequently missing teeth. Tooth shape may vary, and conical and narrow crowns are common. Nail dysplasia affects finger- and toenails, and is often more severe in childhood. Nails may be spoon-shaped, rigid, slow-growing and easily broken. The clinical and radiographic features of a mother and child presenting with this rare condition are described.

Abstract
Intravascular papillary endothelial hyperplasia (IPEH) is an unusual vascular lesion of proliferating endothelial cells. It is more frequently seen in the extremities, particularly in the fingers. Oral IPEH has been reported with the common sites being lip, tongue, and buccal mucosa. In this article, we present a case of oral IPEH of the floor of the mouth, an unusual location, presenting in a 9-month-old male. The histogenesis, histologic features, and ultrastructural features are also reviewed. A misdiagnosis of angiosarcoma can be made in a case of IPEH due to similar histopathologic features. It is imperative to rule out this error by an elaborate histopathologic evaluation ofthese lesions.

Abstract
BACKGROUND Habitual arecanut chewing is associated with Oral Submucous Fibrosis (OSF). High copper content in arecanut plays a vital role in pathogenesis of OSF. This study evaluates the copper-staining pattern of buccal epithelial cells in oral cytological smears of non-chewers, chewers, and OSF. MATERIALS & METHODS Alcohol fixed buccal epithelial smears of 10 histopathologically confirmed cases of OSF, 10 chewers without lesion, and 5 nonchewers were stained with modified Rhodamine technique and studied under the light microscope. Buccal epithelial smears of non-chewers dipped in copper sulphate solution were used as known positive for copper. RESULT Copper appeared as shades of palered within the cytoplasm of chewers and did not show any stain in non-chewers. Intense red stain was seen in OSF smears as dark granules within the cytoplasm. CONCLUSION Intense staining of copper in OSF buccal smears, than in the chewers supports the role of copper in the pathogenesis of OSF.

Abstract
INTRODUCTION Human immunodeficiency virus (HIV) infection is a major health problem in India. The importance of oral lesions as clinical features of HIV infection and their gender specificity have been reported worldwide. However, there are very few reports on this aspect from the Indian subcontinent. MATERIALS AND METHODS The study population comprised 1000 consecutive HIV seropositive patients presenting to YRG CARE, a non-governmental organisation in Chennai, South India. The oral lesions were diagnosed based on clinical appearance using international criteria. Data were entered into a database and analysed using the SPSS package. RESULTS The male-to-female ratio was 3.4:1, and 95% of the patients had acquired infection via heterosexual contact. Majority of the patients (84%) were in the 21- to 40-year-old age groups. Pulmonary tuberculosis (12%) was the most common systemic finding. Oral lesions were seen in 86.6% of the patients. Gingivitis (72.3%) and periodontitis (33.2%) were the most common lesions followed by oral pigmentation (26.3%), oral candidiasis (23.8%), angular cheilitis (7.9%), oral ulcers (3.3%), oral hairy leukoplakia (2.1%), oral submucous fibrosis (0.9%) and leukoplakia (1.5%). The prevalence of oral candidiasis, periodontitis and oral hairy leukoplakia was higher in males than in females. CONCLUSIONS Oral lesions occur commonly in HIV infection. A comprehensive oral examination plays an important role not only in the management of the patients, but also in assessing the immune status and in their follow-up.

Abstract
BACKGROUND Oral submucous fibrosis (OSF) is a pre-cancerous condition caused by the use of areca nut in various forms. There are very few published reports on areca nut use and OSF from Chennai, South India. METHODS A hospital-based case-control study on habits and OSF was performed in Chennai over a 3-year period. A total of 185 consecutive patients with OSF were matched with age- and sex-matched controls. History was recorded in a pre-determined format by qualified dental surgeons. RESULTS The male to female ratio of OSF cases was 9.9 : 1. All areca nut products were associated with OSF, with the risk being greatest for pan masala. The duration of the habit was more significant than the frequency of the chewing habit. CONCLUSION The present study confirms the strong association between areca nut use and OSF and the increasing use of pan masala.

Abstract
Talon cusp is a dental anomaly, which is present as an accessory cusp and is seen both in the deciduous and permanent dentition. It may occur unilaterally or bilaterally and has been reported mostly in maxillary teeth, with a few cases occurring in the mandible. Talon cusp is usually asymptomatic; however, there are many clinical problems associated with it. Talon cusp is clinically manifested in three forms: talon, semi-talon and trace talon. In this article, we present four case reports of talon cusp with an overview of different clinical variants of talon cusp, classification, etiopathogenesis, associated syndromes, clinical problems, and treatment modalities.
