Prevalence of oral potentially malignant disorders (OPMD) in adults of Western Maharashtra, India: A cross-sectional study.

Background: Oral cavity cancer is estimated to be the third most common malignancy after cancer of cervix and stomach in developing countries. Objectives: The objective of this study is to investigate the relationship between smoking, alcoholic consumption, betel quid chewing, and OPMD in a prospective manner. Materials and Methods: A descriptive, cross-sectional study was conducted among 35-55-year-old adults of Western Maharashtra, India. Oral cavity examination as recommended by the American Dental Association specification was followed. Data recorded were transferred from precoded survey pro forma to the computer. The prevalence of OPMD was assessed by determining the percentage of the study population affected. Analysis was done to find out the risk of oral premalignant disorders. The Chi-square (x2) test and adjusted odds ratio (ORs) with 95% confidence interval (CI) were calculated. The Statistical Package for the Social Sciences (SPSS) software version 21.0 was used for the statistical analysis and significance level was set at P < 0.05. Results: Odds of having OPMD are five times higher for those who smoke (OR = 5.78; 95% CI, [6.18, 7.82]) as compared to those who do not. The odds of suffering from OPMD are about five times higher among those who chew as compared to those who do not (OR = 4.98; 95%CI, [2.91, 7.28]). The mean frequency of tobacco chewing per day and duration in years in participants with OPMDs was significantly higher as compared with normal oral mucosa (P < 0.05 and P < 0.05), respectively, in the use of different tobacco forms. Conclusion: These findings can be used to design case control or cohort studies to further understand the relation between habits and OPMD.

Correlation of Troponin I with Left Ventricular Ejection Fraction in Acute Coronary Syndrome.

Coronary artery disease is the most common cause of heart disease and the single most important cause of premature death in the world.In 2001,CVD was responsible for 29% of all deaths and 14% of the 1.5 billion lost DALYs.By 2030,when population is expected to reach 8.2 billion,33%of all deaths will be caused by CVD. Over the last decade, cardiovascular disease(CVD) has become the single largest cause of death worldwide. Myocardial necrosis causes release of structural proteins and other intracellular macromolecules into the cardiac interstitium as a consequence of compromise of the integrity of cellular membranes. On the basis of improved sensitivity and superior tissue-specificity compared with the other available biomarkers of necrosis, cardiac troponin is the preferred biomarker for the detection of myocardial injury. Material and Objectives:

Awareness and knowledge of tobacco associated risk of development of oral cancer and oral potentially malignant disorders among patients visiting a dental college.

INTRODUCTION: Cancer is considered as a serious health problem in public with an increasing number of cancer patients reported every year hence public health awareness/knowledge on oral cancers oral potentially malignant disorders (OPMDs) and their risk factors is crucial for prevention and early detection of OPMD and it is important to prevent transformation of oral cancer. MATERIALS AND METHODS: A cross-sectional survey with an interviewer-administered questionnaire was conducted. The questionnaire consists of relevant questions to ascertain sociodemographic information, awareness, and knowledge of Oral cancer and OPMDs, and their associated risk factors, and participants exposure to risk factors. Subjects above the age of 20 years (n = 200) were randomly selected, and the questionnaires were administered by the interviewer while they were waiting for treatment. RESULTS: Results showed lack of awareness for OPMDs based on the evaluation of the questionnaires for sociodemographic data. CONCLUSION: Awareness about oral cancer is relatively significant; however, for OPMDs, awareness is low in our study and the subjects were unaware of the risk factors. So a high level of public awareness and knowledge of OPMDs should be brought to people via mass media as it is a very effective source of information. Early detection of oral cancer is the most effective means to improve survival and to reduce morbidity.

Analysis of expression of p53, p63 and proliferating cell nuclear antigen proteins in odontogenic keratocyst: An immunohistochemical study.

BACKGROUND: Odontogenic keratocyst (OKC) is a benign intraosseous lesions (within the jaw bone) of odontogenic origin that account for about 10% of jaw cysts. They are characterized by an aggressive behavior with a relatively high recurrence rate. Early diagnosis and follow-up of the patient with OKC is important because the possibility of such patient there is develop to other features of Nevoid basal cell carcinoma syndrome in future. Considering the roles and effects of p53, p63 and proliferating cell nuclear antigen (PCNA) in cells proliferation, this study was designed. OBJECTIVES: To understand the behavior of epithelial cells in pathogenesis and biological aspects of OKC in diagnosis. MATERIALS AND METHODS: Immunohistochemical (IHC)technique was performed in 21 cases of OKCs. RESULTS: Immunological stained p53 cells were mainly located in the suprabasal layers. p63 and PCNA-positive cells were found throughout the lining epithelium including basal and suprabasal cell layers. The intensity of staining was more in p63 and PCNA than the p53 expression of the cystic epithelial lining. CONCLUSIONS: It is possible that the biological behavior of OKCs may be related to the suprabasal proliferative compartment in the cystic epithelium as observed. These proteins may participate in the regulation of epithelial cell differentiation. Taken together, these data may favor tumerigenesis on OKCs.

Sociodemographic and behavioral factors associated with early childhood caries among preschool children of Western Maharashtra.

INTRODUCTION: Early childhood caries is a preventable disease of multifactorial etiology and is a public health problem affecting majority of the preschool-age children of the country. If left untreated, it has many social, economic, and nutritional implications and affects the quality of life of the affected child. METHODS: This cross-sectional study was conducted among 200 preschool children of Karad city, western Maharashtra, to assess the prevalence of dental caries among the preschool children and to assess the factors affecting the development of dental caries. Various child-level, parent-level, attitudinal- and family-level factors, and clinical variables were evaluated. RESULTS: High prevalence of caries of 87.5% was observed in the study sample. Bivariate analysis showed a significant association of age of child (P < 0.001), age of mother at birth (P = 0.041), feeding during 1st year (P = 0.034), snacking habits (P = 0.001), and brushing frequency (P = 0.03) with dental caries. On multivariate analysis, the factors of snacking habits (P = 0.003) and age of child (P = 0.002) remained significantly correlated with dental caries. CONCLUSION: There was a strong and consistent relation of the snacking habits with the prevalence of dental caries among the preschool children of Karad city. There is a need to sensitize the caregivers regarding the role of frequent snacking in dental caries.

Oral Health Status and Dental Treatment Needs of 5-12-year-old Children with Disabilities Attending Special Schools in Western Maharashtra, India.

INTRODUCTION: The individuals suffering from various disabilities form a considerable proportion of the community. The psychological reactions associated with a deformity can be devastating to the disabled, parents, caregivers, and family which often lead to attitudes of hopelessness in the lives of these disabled individuals. OBJECTIVES: To assess the oral health status and treatment needs among 5-12-year-old children attending special school in Western Maharashtra, India. MATERIALS AND METHODS: A descriptive cross-sectional study was conducted among 5-12-year-old children attending specials school in Western Maharashtra, India. The study group consisted of 100 children (62 males and 38 females). The oral health status was assessed by using decayed, missing, and filled teeth (DMFT) index, Community Periodontal Index, Dentition status and treatment needs. Information on disability status, intelligent quotient, and systemic diseases were recorded. RESULTS: The mean age of the study population was 9.35 ± 2.92 years. There were 62 (62%) males and 38 (38%) females in the study population. Among the total children examined, 50% of the children were suffering from mental retardation (MR), followed by MR with cerebral palsy (20%). The overall mean decayed and filled teeth and DMFT scores were 3.53 ± 1.02 and 3.89 ± 1.30, respectively, and decayed component had the highest score in both the groups. A statistically significant difference has been observed among the gender (P < 0.001). CONCLUSION: There is a high proportion of dental treatment needs required for these children which reflect the barriers to access and utilize oral health care among these children. As dentist, we should emphasize on health education, periodic recall, and monitoring among these individuals.

Influence of risk factors on patients suffering from potentially malignant disorders and oral cancer: A case-control study.

BACKGROUND: Tobacco use can alone lead to death worldwide, especially in developing and underdeveloped countries. China and Brazil are the world's largest producer of tobacco. India holds the third place in producing, and it is the fourth largest consumer of tobacco and its products in the world. OBJECTIVES: A case-control study was carried out to assess the influence of risk factors on patients with potentially malignant disorders (PMD) and oral cancer. MATERIALS AND METHODS: Fifty cases diagnosed with PMD and oral cancer patients were selected for the study. An equal number 50 healthy controls who were also selected after age and gender matching. Multivariate logistic regression analysis was used to estimate the suspected risk factors for PMD and oral cancers. Chi-square test, Adjusted odd's ratios with 95% confidence interval were also used for the statistical analysis. RESULTS: There is a statistically significant difference between the different age group, duration, frequency, exposure time, and synergistic effect of tobacco chewing, smoking and alcohol drinking. CONCLUSIONS: Chewing tobacco is one of the major risk factors in the initiation of PMD which can lead to oral cancer.

Glucose Level Estimation in Diabetes Mellitus By Saliva: A Bloodless Revolution.

BACKGROUND: Diabetes mellitus is a massive, growing, silent epidemic that has the potential to cripple health services in all parts of the world. Currently, a diagnosis of diabetes is achieved by evaluating plasma glucose levels. Saliva offers some distinctive advantages. Whole saliva can be collected non-invasively and by individuals with limited training. The present study was aimed to estimate and correlate the plasma and salivary glucose levels in diabetic and non diabetic subjects, with special reference to age. METHOD: The study population consisted of three groups: Group I consisted of diabetics with BGL>200mg/dl and Group 2 consisted of diabetics with BGL 130-200mg/dl based on their random plasma glucose levels. Group 3 consisted of healthy population as controls with BGL <130 mg/dl. 2 ml of peripheral blood was collected for the estimation of random plasma glucose levels and unstimulated saliva was collected for the estimation of salivary glucose RESULTS: The salivary glucose levels were significantly higher in group 1 and group 2 diabetics when compared with controls. The salivary glucose levels show a significant correlation with plasma glucose levels between study populations, suggesting that salivary glucose levels can be used as a monitoring tool for predicting glucose level in diabetic patients. CONCLUSION: The present study found that estimation of salivary glucose levels can be used as a noninvasive, painless technique for the measurement of diabetic status of a patient in a dental set up.

Analysis of various risk factors affecting potentially malignant disorders and oral cancer patients of Central India.

CONTEXT: The use of tobacco/betel quid can alone lead to death. India is the fourth largest consumer of tobacco/betel quid in the world and the third-largest producer of tobacco/betel quid after China and Brazil. AIMS: A case-control study was carried out to assess the prevalence and various risk factors among potentially malignant disorders (PMD) and oral cancer patients of central India. SETTINGS AND DESIGN: A total of 100 clinically and histopathologically diagnosed PMD and oral cancer patients were selected for the study. MATERIALS AND METHODS: A histopathologically confirmed 100 patients who were suffering from PMD and oral cancers were selected and an equal number 100 healthy controls who were age- and sex-matched at par with the cases were also examined and interviewed. Chi-square (χ(2)) test and adjusted odds ratio (ORs) with 95% confidence interval (CI) were calculated to estimate the suspected risk factors for PMD and oral cancers by using multivariate logistic regression analysis. Significance level was set at P < 0.05. RESULTS: Statistically significant difference was observed in the age group, socioeconomic status (SES), duration, frequency, exposure time and synergistic effect of tobacco/betel quid chewing, smoking, and alcohol drinking in our study population. CONCLUSIONS: Chewing tobacco/betel quid is a strong risk factor in the development of PMD and oral cancer. Also age, gender, SES, education, and occupation influence the development of PMD and oral cancer.

Antifungal efficacy of Punica granatum, Acacia nilotica, Cuminum cyminum and Foeniculum vulgare on Candida albicans: an in vitro study.

BACKGROUND: The establishment and maintenance of oral microbiota is related not only to interbacterial coaggregations but also to interactions of these bacteria with yeasts. Hence, it is important for agents used in the treatment of oral diseases to have antifungal properties for effective therapy. OBJECTIVE: The main purpose of this study was to evaluate the in vitro antifungal efficacy of Punica granatum, Acacia nilotica, Cuminum cyminum and Foeniculum vulgare on Candida albicans. MATERIALS AND METHODS: The pomegranate peel is separated, dried and powdered. Fennel, cumin and acacia bark obtained from the tree are powdered. Candida is inoculated at 37˚C and seeded on Sabourauds agar medium. Sterilized filter papers saturated with 30 µl of the extracts are placed on the seeded plates and inoculated at 24 and 48 h. Zones of inhibition on all four sides are measured around the filter paper with a vernier caliper. The experiments were repeated on four plates, with four samples of each extract on one plate for all of the extracts. RESULTS: All the above-mentioned ingredients showed antifungal property, with Punica granatum showing the highest inhibition of Candida albicans with a mean zone of inhibition of 22 mm. P-values <0.05 were obtained for Punica granatum when compared with the other extracts. CONCLUSION: The results showed the potential use of these products as cheap and convenient adjuvants to pharmaceutical antifungal products.

Dental caries vaccine.

Dental caries is one of the most common diseases in humans. In modern times, it has reached epidemic proportions. Dental caries is an infectious microbiologic disease of the teeth that results in localized dissolution and destruction of the calcified tissue. Dental caries is a mulitifactorial disease, which is caused by host, agent, and environmental factors. The time factor is important for the development and progression of dental caries. A wide group of microorganisms are identified from carious lesions of which S. mutans , Lactobacillus acidophilus , and Actinomyces viscosus are the main pathogenic species involved in the initiation and development of dental caries. In India, surveys done on school children showed caries prevalence of approximately 58%. Surveys among the U.S. population showed an incidence of 45.3% in children and 93.8% in adults with either past or present coronal caries. Huge amounts of money and time are spent in treating dental caries. Hence, the prevention and control of dental caries is the main aim of public health, eventually the ultimate objective of public health is the elimination of the disease itself. Recently, dental caries vaccines have been developed for the prevention of dental caries. These dental caries vaccines are still in the early stages.

Assessment of atmospheric microbial contamination in a mobile dental unit.

INTRODUCTION: Bioaerosols are important considerations in infection control as well as in occupational health. Bioaerosols may carry potentially hazardous microbes, viruses, fungi, allergens, and other toxic substances that may harm the dental operator, patient, and the dental assistant by causing nosocomial infections. OBJECTIVE: To assess the level of atmospheric microbial contamination before, during, and after dental treatment procedures in the dental operatory of a mobile dental unit (MDU). MATERIALS AND METHODS: The study included three treatment sessions on different working days, with an interval of one month. The MDU was fumigated before the start of the study. Brain Heart Infusion Agar with 5% sheep blood was used to collect the gravitometric settling of aerosols produced before, during, and after dental treatment procedures. The agar plates were sent for aerobic and anaerobic culture. RESULTS: The results showed that atmospheric microbial contamination (CFUs/plate) was 4 times higher during working sessions as compared to the levels before the working sessions. At the end of the working day, aerosols decreased by almost 3 times that seen during work. CONCLUSION: The aerosols increased during and after work sessions. This shows the increased risk of transmission of infectious agents to the dentists who work in the MDU. Hence, all necessary preventive measures should be advised and need to be followed strictly.
