Background: Procrastination may be conceptualized as a behavioral self-handicap. In education and training, the term academic procrastination is commonly used to denote the delay in academic activities. A person who procrastinates starts feeling powerless and hopeless; his confidence suffers and future seems dark and can lead to low self-esteem. Aim: The aim of this study was to assess the relationship between academic procrastination and self-esteem among dental students in Bengaluru City, Karnataka, India. Material and Methods: The current cross-sectional study was conducted among dental students from three different dental institutions in Bengaluru. The sample consisted of 255 dental students. Data were collected through questionnaire using the Tuckman Academic Procrastination Scale and Rosenberg Self-Esteem Scale. The data collected were analyzed using SPSS software version 14.0. Independent Student's t-test, ANOVA, and Pearson's correlation test were performed. P < 0.05 was considered statistically significant. Results: The results indicated that a significant weak positive correlation (r = 0.25, P < 0.001) existed between academic procrastination scores and self-esteem scores. There was a significant difference in the mean score of academic procrastination between males (40.81 ± 6.87) and females (42.80 ± 7.25) (P = 0.03). Conclusions: The current study found out that students with high self-esteem procrastinate less, whereas those who procrastinate more have comparatively lower self-esteem. Timely intervention can help students improve their skills such as time management and study habits.

Background: Disparity exists in the availability of dental care services in rural India as compared to urban setup. Majority of dental offices are set in urban areas, with little access to rural population, driving people to primary health centers for all health needs. In situations like these, auxiliary health workers can be delegated with the duties of oral health education to the masses provided they possess adequate information/knowledge regarding oral healthcare and practices. Aim: The aim of this study is to assess the influence of oral health knowledge (OHK) and oral health practices on the oral health status among auxiliary health workers in the health centers of Mangalore. Material and Methods: A cross-sectional study was carried out among the auxiliary health workers in Mangalore. OHK and practices were analyzed using a pretested, screening questionnaire. Oral health status was analyzed using the WHO Oral Health Assessment Form-1997. Data were analyzed using the Statistical Package for the Social Sciences software, version 16.0 (SPSS Inc., Chicago, IL, USA). Chi-square test and binary logistic regression test were employed. P < 0.05 was considered statistically significant. Results: Majority (72.8%) of the auxiliary workers had good OHK and followed recommended dental practices. Better OHK was associated with better oral health, namely lesser decayed teeth and more filled teeth (P < 0.05). Better OHK correlated negatively with missing teeth among participants (P < 0.05). Visiting a dentist in previous 6 months, brushing twice a day, and changing brush every 3 months were the important predictors of improved oral health (P < 0.05). Conclusion: Better OHK and practices can significantly impact the oral health status of auxiliary health workers in Mangalore. It also projects the impact that it can have on the oral health of rural population as auxiliary health workers are the first line of information for the underprivileged masses. Dedicated oral health programs to educate/train auxiliary workers in health centers can form an alternative approach to reach rural population.

Introduction: Fluoride is one of the indispensable elements for the living being. However, the intake of F above the threshold level can affect the central nervous system even before causing dental or skeletal fluorosis. Aim: The aim was to assess the effect of fluoride in drinking water on the intelligence quotient (IQ) of 8-12 years old school going children residing in high and low Fluoride (F) areas of Delhi. Materials and Methods: A total of 200 school children were selected, 100 from low F area and 100 from high F area. The IQ of the children was assessed using Ravens Standardized Progressive Matrices Test. Information for each child's sociodemographic data, mother's diet during pregnancy, duration of residency in the village, source of drinking water, and duration of drinking water from the source was entered on a specially designed proforma from mothers of children. Height and weight were also recorded for each child to assess the nutritional status. Independent t-test and Chi-square test was used to compare mean IQ scores in high and low fluoridated areas. Pearson's correlation and multivariate linear regression were used to appraise the issue of all the study variables on IQ. Results: Comparison of mean IQ of children in both high (76.20 ± 19.10) and low F (85.80 ± 18.85) areas showed a significant difference (P = 0.013). Multiple regression analysis between child IQ and all other independent variables revealed that mother's diet during pregnancy (P = 0.001) along with F in drinking water (P = 0.017) were the independent variables with the greatest explanatory power for child IQ variance (r² = 0.417) without interaction with other variables. Conclusion: Fluoride in the drinking water was significantly related with the IQ of children. Along with fluoride, mother's diet during pregnancy was also found to be significantly related with IQ of children. Researches in the same field are further advocated with large sample size and over a large geographical area.

Purpose: This cross-sectional study assessed smoking-related behaviors, experiences, beliefs, knowledge, and prevalence among a sample of college going students. It helped to inform them about the different nicotine replacement therapies (NRTs) available for the cessation of the habit. Materials and Methods: After gaining informed consent, 500 college going students (18-25 years age group) of Swami Devi Dyal Group of Colleges, who are smokers and also willing to participate in the study were surveyed regarding their awareness about and prevalence of ill effects of smoking. The survey was conducted by employing a uniform questionnaire. The questionnaire assessed about the tobacco use, no of cigarettes they smokes every day, what form of smoking do they prefer, early smoking experiences and sensations, factors that might motivate a quit attempt, ill effects of smoking on oral health, other psychosocial variables associated with adolescent smoking and about the different NRTs available. The feedback hence obtained was condensed in the form of objective results, which were analyzed to arrive at meaningful conclusions. Results and Conclusion: According to the study as many as about 90% of the students have reasonably good chances of succeeding in quitting smoking. However, the overwhelming majority (96%) had no idea about different NRTs. This shows a stark lack of awareness as to the means that can help them quit the habit. Thus, we get a clear vision as to the direction of our efforts and feel optimistic as to the outcome too.

Background: Caries inhibitory effect of fluoride has been known for about a century. The use of mouthrinses as a vehicle for applying fluoride in a self-administered preventive program was first proposed by Bibby et al. in 1946. Since then sodium fluoride (NaF) mouthrinses have been used extensively as a caries-preventive measure. Aim: To determine the effectiveness of NaF mouthrinses in the prevention of Dental Caries through a systematic review. Materials and Methods: A search strategy for the review was carried out according to the standard Joanna Briggs Institute systematic review methodology. An electronic search was carried out in PubMed, Medline, Google Scholar, and Cochrane Library from 1970 to 2012. Hand search was conducted through the reference list of articles. The main intention of our investigation was to check the amount of reduction in clinical dental caries. Of 657 articles originally identified, 35 records were considered potentially eligible and sought for further assessment. Results: A total of 28 articles met the inclusion criteria and were assessed independently for methodology and performance. Randomized control study design was followed in 17 studies mainly at evidence level; 2 with a preventive fraction ranging from 16% to 65%. The reported mean annual caries reduction among adolescents was 0.76. Conclusion: Daily or weekly NaF mouthrinses had a significant caries reduction among adolescents. Daily and weekly/fortnightly rinse programs showed an average of 39% fewer decayed-missing-filled-surface. Daily use of NaF had a slightly higher caries reduction rate. Not enough data are available to show the effect of fluoride mouth rinsing programs on deciduous dentition.

Introduction: The dental profession has been considered a stressful occupation. The origins of this stress may also lie in the process of dental education. The perception of stress is frequently influenced by one's personal system of beliefs and attitudes. Aim: The aim was to assess the relationship between psychological well-being and perception of stress among undergraduate dental students in Bangalore city. Materials and Methods: A cross-sectional questionnaire survey was conducted among 800 1-4 ^th year dental students. Information on demographics, social background, and health behaviors were collected. The psychological general well-being (PGWB) index and the dental environment stress (DES) questionnaire were used to measure PGWB and perceptions of stress, respectively. Multiple intergroup comparisons were carried out using ANOVA. Correlation analysis was done to find out relationship between PGWB and DES. Regression analysis to find out the strongest predictor of PGWB. P <0.05 was considered as statistically significant. Results: There was no significant difference in PGWB among different year of study. Female students had significantly lower PGWB scores and higher DES scores than male students. The stress differed among different year of study with highest stress in final year students in all domains except for clinical/preclinical training, which was highest among 1 ^st year students. Correlational analysis showed a negative relationship between PGWB and DES score. Stepwise multiple regression analysis revealed that "workload," "patient treatment," "performance pressure" and "others" domains of stress were significant predictors of PGWB. Conclusion: This study revealed that the perception of stress is influenced by gender and health behaviors which in turn affect PGWB.

Background and Objectives: Preventive approach in dental practice has been cited as a reason for the decline in oral diseases and as a predominant part of the service-mix of dental practices in the future. Dental faculty's knowledge and attitude toward prevention are important, since they have exceptionally important direct and indirect roles in shaping student's preventive orientation and also potentially influencing their patient's ability to take care of their teeth. Thus, this study was conducted to assess knowledge and attitudes toward preventive dental care among dental faculties and their relation to demographic and professional characteristics. Materials and Methods: A cross-sectional study was conducted among dental faculties in Bangalore city. Of 17 dental colleges, 4 were selected by simple random sampling. A total of 218 dental faculties was individually asked to complete a pretested questionnaire. The questionnaire requested information on dental faculty's demographic and professional characteristics and their knowledge and attitudes toward preventive dental care. Descriptive, Chi-square tests, and ANOVA were used to analyze the data. Results: The highest knowledge was seen among dental faculties regarding prevention of malocclusion (3.51 ± 1.02) followed by oral cancer (2.95 ± 1.09) and periodontal diseases (2.86 ± 1.02). The least knowledge was seen for the prevention of caries (2.63 ± 1.35). The most positive attitudes regarding preventive dentistry was characterized as being essential (6.34 ± 1.05), useful (6.32 ± 1.07) and valuable (6.27 ± 1.00). Statistically significant differences were found in relation to knowledge and attitudes for all demographic and professional characteristics except for gender and Department of Teaching. Conclusion: Dental faculty seems to have differing levels of knowledge regarding oral diseases with positive attitudes seen regarding preventive dentistry. Continuing education activities and placing emphasis on prevention-related research are recommended.
