Survey on attitude of dental professionals about plagiarism in Maharashtra, India.

PURPOSE: Plagiarism is a type of research misconduct that consists of copying other's work or ideas without giving them proper credit. The rise of plagiarism cases has become a serious concern in the scientific world. Hence, a cross-sectional survey was carried out to assess the attitude among dental faculty members and postgraduate (PG) students toward plagiarism. Objectives were to compare the attitudes of dental faculty members and PG students toward plagiarism and to analyze the association of attitude toward plagiarism (ATP) with age, gender, and number of publications of the participants. MATERIALS AND METHODS: ATP was measured using a self-administered questionnaire consisting of two sections; first section consisting of demographic details of the participants and second section consisting of the ATP questionnaire measuring positive attitude, negative attitude, and subjective norms. Ninety faculty members and 126 PG students from four dental institutions participated in the study. The data were analyzed using Chi-square test and linear regression analysis. RESULTS: PG students showed more positive attitude and less negative ATP as compared to faculty members. Positive ATP decreased with increase in age (ß = -0.147; P = 0.008), number of publications (ß = -0.195; P = 0.001), and from males to females (ß = -1.209; P = 0.044) whereas negative ATP increased with age (ß =0.093; P = 0.001). CONCLUSION: The study showed negligence of PG students toward plagiarism which calls for improvement in awareness regarding plagiarism and research education.

Estimating the carbohydrate content of various forms of tobacco by phenol-sulfuric acid method.

BACKGROUND: Due to consumption of various forms of tobacco in large amounts by Indian population, it has become a cause of concern for major oral diseases. In 2008, the WHO named tobacco as the world's single greatest cause of preventable death. It is also known that certain amount of carbohydrates are incorporated in processed tobacco to make it acceptable for consumption. Thus, its role in oral diseases becomes an important question at this point of time. Through this study, it is attempted to find out the carbohydrate content of various forms of tobacco by phenol-sulfuric acid method. MATERIALS AND METHODS: Tobacco products selected for the study were Nandi hookah tambakhu (A), photo brand budhaa Punjabi snuff (B), Miraj (C), Gai-chhap tambakhu (D), Hanuman-chhap Pandharpuri tambakhu (E), and Hathi-chhap Bidi (F). The samples were decoded and transported to laboratory and tested at various concentrations by phenol-sulfuric acid method followed by ultraviolet spectrophotometry to determine their absorbance. RESULTS: The present study showed Hathi-chhap bidi/sample F had a maximum absorbance (1.995) at 10 µg/ml which is a smoking form of tobacco followed by rest all smokeless forms of tobacco, i.e. sample C (0.452), sample B (0.253), sample D (0.077), sample E (-0.018), and sample A (-0.127), respectively. CONCLUSION: As the concentration of tobacco sample increases, their absorbance increases which in turn is suggestive of increase in its carbohydrate concentration. Carbohydrates in the form of sugars, either inherently present or added in it during manufacturing can serve as a risk factor for higher incidence of dental caries.

Comparative assessment of antimicrobial efficacy of different hand sanitizers: An in vitro study.

BACKGROUND: To evaluate the antimicrobial efficacy of four different hand sanitizers against Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, Escherichia coli, and Enterococcus faecalis as well as to assess and compare the antimicrobial effectiveness among four different hand sanitizers. MATERIALS AND METHODS: The present study is an in vitro study to evaluate antimicrobial efficacy of Dettol, Lifebuoy, PureHands, and Sterillium hand sanitizers against clinical isolates of the aforementioned test organisms. The well variant of agar disk diffusion test using Mueller-Hinton agar was used for evaluating the antimicrobial efficacy of hand sanitizers. McFarland 0.5 turbidity standard was taken as reference to adjust the turbidity of bacterial suspensions. Fifty microliters of the hand sanitizer was introduced into each of the 4 wells while the 5th well incorporated with sterile water served as a control. This was done for all the test organisms and plates were incubated in an incubator for 24 h at 37΀C. After incubation, antimicrobial effectiveness was determined using digital caliper (mm) by measuring the zone of inhibition. RESULTS: The mean diameters of zones of inhibition (in mm) observed in Group A (Sterillium), Group B (PureHands), Group C (Lifebuoy), and Group D (Dettol) were 22 ± 6, 7.5 ± 0.5, 9.5 ± 1.5, and 8 ± 1, respectively. Maximum inhibition was found with Group A against all the tested organisms. Data were statistically analyzed using analysis of variance, followed by post hoc test for group-wise comparisons. The difference in the values of different sanitizers was statistically significant at P < 0.001. CONCLUSION: Sterillium was the most effective hand sanitizer to maintain the hand hygiene.

Comparative Assessment of Antimicrobial Efficacy of Different Antibiotic Coated Gutta-Percha Cones on Enterococcus faecalis An Invitro Study.

INTRODUCTION: The major goal of endodontic treatment is to eliminate bacteria from the root canals and prevent re-infection. Enterococcus faecalis (E. faecalis) has been attributed to be the most common organism for the endodontic treatment failures. The choice of endodontic material that have high antimicrobial efficacy can help in decreasing/avoiding growth of micro-organisms and facilitate the success rate of treatment. AIM: The present study was designed with an aim to evaluate the antimicrobial efficacy of antibiotic coated gutta-percha cones on E. faecalis. MATERIALS AND METHODS: The present study was an invitro experimental study, conducted at Department of Public Health Densitry and Department of Microbiology. Gutta-percha cones were coated with different medicaments like Zinc Oxide-Eugenol cement (ZOE i.e. Group A), ZOE plus Amoxicillin-Clavulanic acid combination (Group B), ZOE plus Amoxicillin (Group C), ZOE plus Ofloxacin-Ornidazole combination (Group D). Agar plates were inoculated with E. faecalis and antibiotic coated gutta-percha cones along with conventional gutta-percha cones (coated only with ZOE) were placed in those agar plates. After 24hours incubation; diameter of zone of inhibition around gutta-percha stick was considered to assess the antimicrobial activity. Results were statistically analysed with analysis of variance (ANOVA) followed by Tukey post-hoc test for group-wise comparisons. RESULTS: Mean diameter of zone of inhibition (in mm) obtained for Group A, Group B, Group C and Group D were 5±0.03, 26.6±0.05, 21.5±0.04 and 15.8±0.03 respectively. The difference in values of different antibiotics was statistically significant. The p-value < 0.001 was considered statistically significant. CONCLUSION: Group B was most effective against E.faecalis compared to other combinations used which increase the success rate of endodontic treatment as compared to conventional gutta-percha cones.

Comparative Evaluation of Arimedadi Oil with 0.2% Chlorhexidine Gluconate in Prevention of Plaque and Gingivitis: A Randomized Clinical Trial.

INTRODUCTION: Chemical plaque control measures are advocated to maintain proper oral hygiene. Ayurvedic medicines are alternatives considered with minimal side effects to treat systemic diseases and dental diseases. So the present study was conducted to assess the anti-plaque efficacy of Arimedadi (herbal) oil against 0.2% Chlorhexidine gluconate mouthwash. AIM: To assess the anti-plaque efficacy of Arimedadi (herbal) oil against 0.2% Chlorhexidine gluconate mouthwash. MATERIALS AND METHODS: A total of 45 patients aged 18 to 21 years, with mild to moderate gingivitis were recruited and were divided randomly into three groups with 15 subjects in each group. After baseline data, scaling and polishing was performed. Group A, as Control, Group B, Chlorhexidine gluconate mouthwash and Group C used experimental Arimedadi oil mouthwash. Instructions were given to use 10 ml mouthwash twice daily after 30 min of tooth brushing for 1 min till 21 days. Plaque Index (PI) and Gingival Index (GI) were taken to assess Plaque and Gingival health on 7(th) day, 14(th) day and at 21(st) day. The statistical analysis was done using Paired t-test and analysis of variance (ANOVA) followed by Post Hoc test. RESULTS: There was similar improvement in gingival health among both groups compared to control group up to 21 days (p<0.001). However from 14(th) day to 21(st) day there was no difference in gingival health between Chlorhexidine and Arimedadi group (p>0.05). CONCLUSION: Arimedadi oil is equally effective to Chlorhexidine gluconate as an adjunct to mechanical plaque control in prevention of plaque accumulation and gingivitis. Arimedadi oil could be an effective and safe alternative to 2% Chlorhexidine gluconate mouthwash due to its prophylactic and therapeutic benefits.

Effect of conventional and sugar free pediatric syrup formulations on primary tooth enamel hardness: An in vitro study.

OBJECTIVES: To assess and compare the effect of conventional and sugar free pediatric syrup formulations on primary tooth enamel hardness over a period of 14 days. MATERIALS AND METHODS: An in vitro study was done on 40 noncarious deciduous teeth. 10 teeth in each group were dipped in 4 pediatric medicinal syrups (1 sugarfree and 3 conventional) for 1 min thrice daily for 14 days and the enamel surface micro hardness was checked at baseline, 7 th day and 14 th day by Vickers hardness testing machine. The pH, titratable acidity and buffering capacity of the syrups were assessed. RESULTS: The pH of syrups were above critical pH for demineralization of the tooth but tiratable acidity and buffering capacity differed. ANOVA test indicated that the reduction in mean micro hardness was maximum in Group D (Conventional Analgesic syrup) and least in Group A (Sugarfree cough syrup) on 7 th and 14 th day. On intergroup comparison there was no difference (P > 0.05) in micro hardness between Group B (Conventional Cough syrup) and Group C (Conventional Antibiotic). However, highly significant (P < 0.01) difference between the either pair of Group B with Group D, and Group C with Group D on 14 th day. The percentage reduction in micro hardness on 14 th day was maximum for Group D (24.4 ± 2.2) and minimum for Group A (14.0 ± 1.3) which was statistically significant (P < 0.01). CONCLUSION: Sugar free pediatric medicines can be effective in reducing dental erosion and efforts should be made to incorporate sugar substitutes in formulation of pediatric medicines.
