Abstract
INTRODUCTION The classification of odontogenic tumors has been revised from time to time in order to provide unified terminology. This reclassification had considerable impact on their prevalence and frequency distribution. OBJECTIVES This study was aimed to emphasize impact of changing classification systems on prevalence and relative frequency of odontogenic tumors. The secondary objective was to analyze demographics of various histological types of odontogenic tumors in comparison to published literature. Review of Indian studies (1992-2020) elaborating frequency of odontogenic tumors is summarized in the end. METHODS This was a hospital-based retrospective study wherein case files of odontogenic tumors diagnosed from 1990 to 2019 period were retrieved. The classification system used originally at the time of diagnosis was retained and prevalence of odontogenic tumors in three different periods (1990-2004, 2005-2016 and 2017-2019) was compared. Further, prevalence, frequency distribution and demographics of all these tumors (1990-2019) were analyzed using latest World Health Organization 2017 classification. RESULTS A total of 345 odontogenic tumors was diagnosed as per World Health Organization 2017 system of classification from 1990 to 2019. 96.81% tumors were benign and 3.81% constituted malignant odontogenic tumors. However, there was marked increase in prevalence of odontogenic tumors in 2005-2016 (6.2%) period as compared to 1990-2004 (3.87%) and 2017-2019 (3.47%). Ameloblastoma remained the most common tumor in three different periods, whereas keratocystic odontogenic tumor became second commonest tumor in 2005-2016 as compared to odontoma in 1990-2004 and adenomatoid odontogenic tumor in 2017-2019. CONCLUSIONS The continuous evolving systems of classification may partly be responsible for inconsistency in odontogenic tumors, with inclusion of keratocystic odontogenic tumor,and has marked impact on prevalence and frequency distribution of odontogenic tumors. The geographical variations in demographics of odontogenic tumors might reflect genetic and environment influence; however it requires elucidation by further studies.

Abstract
Background: Dental informatics is an evolving branch widely used in dental education and practice. Numerous applications that support clinical care, education and research have been developed. However, very few such applications are developed and utilized in the epidemiological studies of oral submucous fibrosis (OSF) which is affecting a significant population of Asian countries. Aims and Objectives: To design and develop an user friendly software for the descriptive epidemiological study of OSF. Materials and Methods: With the help of a software engineer a computer program SOFPRO was designed and developed by using, Ms-Visual Basic 6.0 (VB), Ms-Access 2000, Crystal Report 7.0 and Ms-Paint in operating system XP. For the analysis purpose the available OSF data from the departmental precancer registry was fed into the SOFPRO. Results: Known data, not known and null data are successfully accepted in data entry and represented in data analysis of OSF. Smooth working of SOFPRO and its correct data flow was tested against real-time data of OSF. Conclusion: SOFPRO was found to be a user friendly automated tool for easy data collection, retrieval, management and analysis of OSF patients.

Abstract
AIM Host-related factors could be important to the fundamental understanding of oral diseases. One such factor is matrix metalloproteinases (MMP). MMP3 (stromelysin 1) is crucial in connective tissue remodeling. Promoter regions are specific segments of DNA that control the rate of mRNA synthesis. Thus, polymorphism in the (5A/6A) promoter region of the MMP3 gene results in different transcriptional activities and is related to susceptibility in diseases. The aim of the present study was to detect polymorphism in the MMP3 gene-promoter region in oral submucous fibrosis patients (OSF), oral squamous cell carcinoma patients (OSCC), and normal individuals with tobacco and areca nut habit and without lesions, and to correlate the genotype as a risk factor in these diseases. METHOD Genomic DNA from blood of OSF (n = 5), OSCC (n = 5), and normal individuals with tobacco and areca nut habit (n = 5) and without (n = 5) were subjected to polymerase chain reaction of the MMP3 gene-promoter region and DNA sequencing. RESULTS The 5A allele in the MMP3 gene-promoter region was observed more frequently in the OSF group than the control groups. No significant difference was noted between OSCC and the control groups on the 5A allele. CONCLUSION The results indicated that the 5A allele of the MMP3 gene-promoter region could be associated with OSF risk factor, but not OSCC, in an Indian population.

Abstract
BACKGROUND The detection frequency of Porphyromonas gingivalis and Treponema denticola in chronic periodontitis (CP) and aggressive periodontitis (AgP) is not explored well in Indian population. AIM The study was undertaken to detect P. gingivalis and T. denticola in CP as well as in AgP patients using polymerase chain reaction (PCR), and to determine the relationship between the frequency of these two microorganisms and the severity of clinical periodontal parameters. MATERIALS AND METHODS Subgingival plaque samples were collected from ninety participants (thirty CP patients, thirty AgP patients, and thirty healthy participants) and the aforementioned two microorganisms were detected using PCR. RESULTS However, when CP and AgP were compared for the detection frequency of two microorganisms, no statistically significant difference was noted. A statistically significant increase in the number of bacteria-positive sites increased as the score of plaque index (PI), gingival index (GI), and clinical attachment level of CP and AgP patients increased. Coexistence of P. gingivalis and T. denticola was frequently observed in deep periodontal pockets. CONCLUSIONS Study findings suggest that P. gingivalis and T. denticola are significantly associated with the severity of periodontal tissue destruction. Statistically significant association exists between clinical periodontal parameters such as PI, GI, periodontal pocket depth (PPD), and clinical attachment loss and presence of both the microorganisms.

Abstract
Introduction: Oral submucous fibrosis (OSF) is a chronic, insidious disease that is associated with significant functional morbidity and an increased risk for malignancy. Turmeric and its active ingredient “curcumin” are being studied upon as chemopreventive agents in various diseases. The present study aims to determine the efficacy of curcumin in the treatment of OSF. Materials and Methods: Thirty clinically diagnosed OSF patients were divided into two groups, 15 patients in each group from the Outpatient Department. Test group patients were treated with Longvida (curcumin) lozenges and control group with Tenovate ointment (clobetasol propionate (0.05%). The treatment was given for 3 months duration and follow-up was done for 6 months. Both the groups were advised for physiotherapy exercises by mouth exercise device. The baseline and follow-up results were compared for IIO (interincisal distance on maximum mouth opening), Visual Analogue Scale (VAS) for normal food and VAS for spicy food. Results: The test group showed 5.93 (±2.37) mm increase in mouth opening compared to 2.66 (±1.76) mm of the control group. In relation to VAS scale with spicy and normal food the average reduction was 64 (42–73) and 77 (70.5–82) as compared to 34 (14.5–64.5) and 64 (46–75.5) respectively in control group. The test group results achieved in the treatment span was sustained in the follow-up (P < 0.05) compared to control group which showed statistically significant (P < 0.05) relapse. Conclusion: It can be concluded that combination strategies for the management of OSF which include the stoppage of causative ill habits, appropriate medicinal and physiotherapy management is more efficient than single therapeutic modality. It is evident from the study that curcumin holds good promise in the treatment of OSF in future.

Abstract
Context: Hepatitis B, a viral disease affecting the liver has high morbidity and mortality. Hepatitis B surface antigen (HBsAg) in serum is used to detect presence of active disease and chronic carrier status. The disease is transmitted predominantly through blood and saliva, hence dental professionals are considered a high risk group. Aim: To detect presence of HBsAg in serum of dental professionals. Subjects and Methods: The study was conducted in two parts viz., one in the year 1991 on 100 dental professionals in Nagpur using reverse passive hemagglutination and the other in 2012 on 50 dental professionals in Chennai using immunochromatography. Results: Ten percent of dental professionals screened in 1991 and 2% of dental professionals screened in 2012 showed HBsAg positive status and were predominantly periodontists with a history of needle-stick injury. Conclusion: This study highlights the importance of Hepatitis B vaccination and periodic evaluation of antibody titer to prevent spread of the disease.

Abstract
Background: Heat-induced alterations to dental and restorative materials can be of great interest to forensic dentistry. Knowing the specific optical behavior of dental materials can be of high importance as recognition of changes induced by high temperatures can lead to the determination of material which was used in a dental restoration, facilitating identification of burned human remains. Aim: To observe the effects of predetermined temperatures (200°C–400°C–600°C–800°C–1000°C) on unrestored teeth and different restorative materials macroscopically and then examine them under a stereomicroscope for the purpose of identification. Materials and Methods: The study was conducted on 375 extracted teeth which were divided into five groups of 75 teeth each as follows: group 1- unrestored teeth, group 2- teeth restored with all-ceramic crowns, Group 3- with class I silver amalgam filling, group 4- with class I composite restoration, and group 5- with class I glass ionomer cement restoration. Results: Unrestored and restored teeth display a series of specific macroscopic & stereomicroscopic structural changes for each range of temperature. Conclusion: Dental tissues and restorative materials undergo a series of changes which correlate well with the various temperatures to which they were exposed. These changes are a consequence of the nature of the materials and their physicochemical characteristics.

Abstract
AIM Oral squamous cell carcinoma (OSCC) is one of the most common malignancies in India. Vascular endothelial growth factor (VEGF), a major mediator of angiogenesis, is known to play a key role in the pathophysiology of tumorigenesis. Polymorphisms of the VEGF gene have been shown to influence the risk of OSCC, but it remains to be elucidated in the Indian population. Thus, the present study was designed to detect the VEGF gene -460 C/T polymorphism in OSCC patients from the Indian population, which is genetically distinct from previously-studied populations. METHODS Peripheral blood samples of 80 OSCC patients and 80 healthy individuals were collected for a case-control study design. The VEGF gene -460 C/T polymorphism was detected by polymerase chain reaction-based restriction analysis. RESULTS The analysis revealed significant differences between normal individuals and patients with OSCC (P < 0.05). The distribution of the TT homozygote and the T allele in the patient group was significantly greater than in the control group. CONCLUSION The present study provides novel evidence of the role of the VEGF gene -460 C/T polymorphism as a suitable genetic marker of OSCC in the Indian population.

Abstract
Context: Oral verrucous hyperplasia (OVH) is a premalignant lesion that may transform into an oral cancer. Aims: The present retrospective study was carried out to analyze the clinico-pathological features of verrucous hyperplasia (VH). Materials and Methods: Total 19 diagnosed cases of verrucous hyperplasia were retrospectively analyzed for demographic, clinical and histopathological features including dysplasia. Results: Average age of occurrence of lesion was 4 th decade of life, with male predominance (2:1) and common site of occurrence being buccal mucosa. Clinically it present as verrucous exophytic growth with sharp or blunt projections on surface, which corresponds histologically. Tobacco lime quid placement in buccal vestibule was key etiologic factor. Histopathologicaly 68% cases showed dysplasia out of which moderate dysplasia predominates (42%). Moderately dysplastic cases were found to be associated with mixed habit pattern. Maximum cases were treated with excision. Conclusion: Biopsy specimen comprising of adjacent normal epithelium is key in distinguishing verrucous hyperplasia from verrucous carcinoma. Clinical behavior and recurrence potential needs to be assessed with long term follow up studies.

Abstract
Background: Radiation given during treatment of oral and pharyngeal malignancy frequently causes alteration of the oral environment predisposing to the colonization of the oral mucosa by yeast species most frequently Candida. Objective: Thus, this study was undertaken in 107 patients to find out association between radiation therapy and frequency of oropharyngeal candidosis, to quantitate colony forming units (CFUs) to identify Candida at species level and to check the incidence of serotype A and B in C. albicans. Materials and Methods: The study was done on patients suffering from oropharyngeal cancer who were advised radiotherapy. The oral rinse collection method was used to collect the sample. Sabourauds Dextrose Agar (SDA) was used as primary culture media and subsequently speciation was done using standard techniques. The strains of C. albicans were serotyped employing the method described by Hansclever and Mitchell (1961, J Bacteriol 1961;82:570-3). Results: 26.16% patients were mycologically positive for candida before radiotherapy with CFUs 100. 14 ± 59.11 that increased to 60.74% patients during radiotherapy with an increase in CFUs to 490.15 ± 207.97. Clinically, grading of mucositis was done and also individual signs and symptoms were noted in each patient. The occurrence of erythmatous lesions, ulceration, and xerostomia were found to be statistically significant (P<0.05). C. albicans was the most frequently encountered species with higher prevalence of serotype A suggesting higher virulent species. Conclusion: It is proposed that in such patients taking radiotherapy prophylactic antifungal treatment should be given specially in patients showing development of oral mucosal lesions such as erythmatous lesions, ulcerations, and complaining about dryness of mouth, that is, xerostomia irrespective of presence or absence of clinical oral candidosis.

Abstract
Human Immunodeficiency Virus (HIV)-related oral lesions can be used as markers of the immune status. The present cross-sectional study was conducted to identify the oral manifestations in HIV-infected individuals and their association with reduced Cluster of Differentiation 4 (CD4) count. The study population included known HIV-positive patients. A detailed case history of 399 HIV-positive patients was obtained and general examination was carried out. Diagnosis of oral lesions was done based on presumptive criteria of EEC Clearinghouse, 1993. The CD4 count was determined in 369 patients and correlated with oral manifestations. The prevalence of oral lesions was found to be 76.70% (n = 306). Oral candidiasis (157 (39.3%)) was the most common oral lesion associated with HIV infection. Amongst various forms of oral candidiasis, erythematous candidiasis (122 (39.3%)) outnumbered the other forms. The mean CD4 count of patients with oral lesions (207 cells/mm(3)) was less than in patients without oral lesions (291 cells/mm(3)) (P = 0.002). Oral candidiasis was found to be significantly correlated to a reduced CD4 cell count below 200 cells/mm(3) (P = 0.000; Odds ratio = 3.1; 95% Confidence interval 1.9-4.9) with good sensitivity, best specificity and positive predictive value. Oral manifestations may be used as an alternative to CD4 count at field-based settings to diagnose the immune compromised status of HIV-infected individuals.

Abstract
OBJECTIVE To assess the efficacy of calcofluor white (CFW) is compared to Gram stain and periodic acid-Schiff in detection of Candida in oral precancer and cancer. STUDY DESIGN The study group consisted of patients with precancer (n = 45), cancer (n = 45) and control group (n = 45). Presence of Candida was confirmed by culture inoculation along with a germ tube and carbohydrate fermentation test. The cytopathologic smears were analyzed by Papanicolaou-CFW and Gram staining, whereas, tissue sections were stained by periodic acid-Schiff and CFW staining. RESULTS Candida albicans was the predominant species identified. A highly significant association of Candida was seen more often in cancer than in precancer. Both in cytology and histopathology Candida detection by CFW was higher. In precancer it was 48.88% in smears and 40% in tissue sections, whereas, in cancer 60% in smears and 55.55% in histopathology. CONCLUSION Among the various diagnostic tools used in the present study, the use of CFW is seen to be a simple, effective, rapid and reliable method, both in cytopathology and histopathology.

Abstract
BACKGROUND Very few reports have been published on the gender specificity of oral submucous fibrosis (OSF) in relation to habit patterns and the severity of disease in the world literature. The purpose of the study was to ascertain the gender specificity for different habits and severity of OSF. METHODS A hospital-based cross-sectional study on various habit patterns associated with OSF was performed in Nagpur over a 5-year period. A total of 1000 OSF cases from 266,418 out patients comprised the study sample. RESULTS The male-to-female ratio of OSF was 4.9:1. Occurrence of OSF was at a significant younger age group (<30 years) among men when compared with women (OR = 4.62, 3.22-6.63, P = 0.0001). Reduced mouth opening, altered salivation and altered taste sensation were found to be significantly more prevalent in women when compared with men. Exclusive areca nut chewing habit was significantly more prevalent in women (OR = 44.5, 25.4-79.8, P = 0.0001). Whereas significant increase for Gutkha (Areca quid with tobacco) (OR = 2.33, 1.56-3.54, P = 0.0001) and kharra/Mawa (crude combination of areca nut and tobacco) (OR = 6.8, 4.36-11.06, P = 0.0001) chewing was found in men when compared with women. CONCLUSIONS There is a marked difference in literacy, socioeconomic status, areca nut chewing habits, symptoms and disease severity in women when compared with men in the central Indian population.

Abstract
The chewing of areca nut is associated with the development of oral submucous fibrosis (OSF), a condition predominantly encountered in Asians indulging in the habit. The pathogenesis of this condition is however, unclear, though several mechanisms have been proposed. Copper has previously been implicated as a possible aetiological factor. In this study, total copper concentration was measured via atomic absorption spectrophotometry in whole mouth saliva of 15 volunteers who were regular chewers, before and after their habitual chew. An aliquot of the latter was also analysed for copper. Six non-chewing volunteers acted as controls. Salivary copper concentrations were corrected for protein content. Over 50% of the subjects had basal salivary copper concentration higher than the range seen in normal controls. All but two subjects demonstrated an increase in the salivary [Cu] following their habitual chew. Marked changes were seen in those with low basal salivary concentrations. These data indicate that soluble copper found in areca nut is released into the oral environment of habitual chewers. Its buccal absorption may contribute to the oral fibrosis in Asians who regularly chew this nut.

Abstract
Oral submucous fibrosis (OSF) is a well-recognised-potentially malignant condition of the oral cavity associated with areca nut chewing. Areca nut has been shown to have a high copper content compared to other commonly eaten nuts, and chewing areca nut for 5-30 min significantly increases soluble copper in whole mouth fluids. Our aims were to determine if tissue and serum concentrations of copper were raised in patients with OSF as a result of chewing areca nut. A panel of buccal mucosal biopsies from patients with OSF from Nagpur, India, was used to measure the tissue concentrations of copper by mass absorption spectrometry (MAS). By MAS, the mean tissue copper level was 5.5+/-2.9 microg/g in the OSF specimens (n=11) compared with 4+/-1.9 microg/g in the non-areca chewing controls (n=7) (P=0.2). Energy dispersive x-ray microanalysis (EDX) was used to identify the presence and distribution of the metal element. EDX showed distinct peaks corresponding to copper (Kalpha 8.04 keV; Kbeta, 8.91 keV) in the epithelium (21/23) and in the connective tissue (17/23) of the OSF specimens compared to spectra obtained from control oral biopsies from non-areca chewing subjects (n=7). These findings were confirmed by secondary ion mass spectrometry (SIMS) analysis in a small number of samples. Serum copper (17.23+/-1.80 pmol/l), caeruloplasmin (0.32+/-0.04 g/l) levels and urinary copper (0.52+/-0.26 micromol/l) in OSF patients (n=14) were within the laboratory reference ranges. The finding of copper in OSF tissue supports the hypothesis of copper as an initiating factor in OSF, playing a role in stimulating fibrogenesis by the upregulation of lysyl oxidase activity.

Abstract
Lysyl oxidase (LO) takes part in the initial steps of converting soluble monomers of collagen and elastin into insoluble fibres in the extracellular matrix. We have studied the immunolocalization of LO as a marker of fibrogenesis in oral submucous fibrosis (OSF). Oral biopsies from 13 subjects with OSF, 6 with histologically confirmed squamous cell carcinoma (SCC) arising in OSF and 10 SCC nonrelated to OSF, were examined. Strong positive staining was observed in 7/13 OSF samples in the cytoplasmic processes of fibroblasts and extracellularly in the upper third of the lamina propria. Furthermore, LO was found to co-localize in the areas stained strongly for collagen and elastin by histochemical stains. Examination of SCC tissues showed localization of LO adjacent to invading epithelial islands as evidence of a stromal reaction both in carcinomas arising from OSF and in SCC from non-OSF cases. These findings suggest that upregulation of LO may be an important factor in the pathogenesis of OSF and in the early stromal reaction of oral cancer.
