BackgroundTo assess the prevalence of malocclusion among 12-18-year-old disabled adolescents in Chennai, Tamil Nadu, India, by using the Dental Aesthetic Index (DAI) and to determine the association of malocclusion with dental caries.MethodsThis cross-sectional study included 243 children with various mental disabilities with or without physical infirmities. The Dental Aesthetic Index (DAI) and the dentition status were recorded using the World Health Organization Oral Health Surveys – Basic Methods (1997) Pro-forma. The Decayed (D), Missing (M) and Filled (F) components of the DMF index were calculated using the Dentition Status and Treatment Need (DSTN). A Chi-square test, ANOVA, and t-test were used to derive inferential statistics.ResultsThe mean DAI score ± standard deviation was 39.0 ± 12.3. A total of 123 (50.6%) participants (74 males and 49 females) had DAI scores of 36 and above, which indicated a handicapping malocclusion requiring mandatory orthodontic treatment. Sixty-nine (28.4%) adolescents (36 males and 33 females) had DAI scores between 31 and 35, which indicated severe malocclusion, for which orthodontic intervention was desirable. Incisal segment crowding (84.8%) was the most common aspect of the malocclusion. The mean DMFT score was 4.36 ± 3.81, and 82.8% of the participants had a DMFT score > 0. There was no statistically significant correlation between the mean DAI and DMFT scores (r = 0.090, p = 0.15). Only 16 (6.6%) of the adolescents had minor or no anomaly not needing orthodontic treatment.ConclusionsThe prevalence of malocclusion and dental caries was found to be high. However, there was no positive correlation between the severity of malocclusion and dental caries among the surveyed disabled adolescents.

Background:A needle stick injury (NSI) is an accidental skin-penetrating stab wound from a hollow-bore needle containing another person's blood or body fluid. Healthcare workers (HCWs) including dental professionals are at an occupational risk of exposure to blood-borne pathogens following NSIs and sharps injuries (SIs). A thorough understanding of the safe practices while handling needles and sharps is crucial for HCWs to create a risk-free work place environment.Aims and Objectives:To assess the knowledge, attitude, practice, and prevalence of NSIs and SIs among dental professionals in a dental college at Bangalore.Materials and Methods:A cross-sectional survey was conducted in September 2012 using a structured, pretested, guided interview-based questionnaire that was administered to 200 dental professionals in a dental college at Bangalore to assess the knowledge, attitude, practices, and self-report information of NSIs.Results:In the present study, 81.5% of dental professionals were vaccinated against hepatitis B. A total of 27.5% participants had an NSI during the previous 12 months. About 41.80% of NSIs occurred during device recapping. Most common reason for failure to report the incidents of NSIs, as declared by 29.09% of the participants, included the fear of being blamed or getting into trouble for having an NSI.Conclusion:The knowledge of dental professionals on NSIs and their preventive measures are inadequate; however, training on Universal Precaution Guidelines, protocols regarding post-exposure prophylaxis, and safety devices has to be provided to prevent such injuries in future among the dental professionals.

Background:The epidemic of tobacco use is one of the greatest threats to global health today. Tobacco attributable deaths in India currently range from 800,000 to 900,000 per year. Adolescents are among the most vulnerable group to start tobacco use. Information on tobacco use among the youth is necessary to establish control measures against it.Objectives:To assess the knowledge, attitude, and behavioral determinants of tobacco use among high school students (age13–15 years) in Bangalore.Materials and Method:A cross-sectional study was conducted over a period of 3 weeks in the month of September 2012. A structured, pretested questionnaire was administered randomly to 500 high school students in Bangalore to assess the knowledge, attitude, and behavioral determinants of tobacco use.Results:Majority of the study population [94.4% (472/500)] believed that smoking is definitely harmful to our health. Also, 39.0% of the participants of age 13 years believed that smoking does not help in socializing and 92.2% of study subjects had negative attitude toward starting the habit. Most of them (83.9%) had a negative perception about smokers that they lack confidence. However, less than 1% of the study population had a habit of smoking at this young age.Conclusion:Awareness of the harmful effects of smoking was high among the study population. The study provides insight into the factors to consider while planning adolescent anti-smoking programs in this and similar settings.

Background:Interactions between oral and systemic health are bi-directional and complex, involving many pathways. The orphans have been sympathized with, ignored, vitrified or even hidden away in the community. Hence, providing health care services for orphans remains a challenge. Oral health education has a positive impact in lowering plaque and gingivitis scores in health educational programs.Objective:The objective of this study is to assess the effectiveness of peer group health promotion model among 11 to 16 year old orphans at Puduchery, South India.Materials and Methods:A clinical trial of 6 months duration was carried out among 72 orphans with age ranging from 11 to 16 years residing in Cluny Padmini Sneha Illam, at Puduchery, India. The baseline data regarding oral health and oral hygiene practices were obtained using a pre-tested close-ended questionnaire. Oral health education was provided to 4 randomly picked children who in turn provided the same to their peer group orphans, supervised by the investigator. Tooth brushes and fluoridated tooth pastes were provided to all the participants throughout the study period. Oral hygiene of the participants was assessed using Modified Plaque Index by Loe H and Gingival Index by Loe H and Silness at baseline, 3rd and 6th month interval. Paired Student t test was used to analyze the categorical data.Results:Majority of the respondents felt consuming sugar was not harmful for dental health, while 15 respondents were not sure about the outcome. When asked if oral hygiene was important for general health, 45.8% were not aware of its association. Although all the participants brushed their teeth daily, none of them reported the use of dental floss. The findings of this study indicated a statisticallysignificant lower mean plaque score of 0.54 ± 0.20 at 6th month when compared to the baseline score of 1.76 ± 0.24. Similarly, statistically significant lower gingival index score of 0.65 ± 0.11 at 6th month was observed when compared to the baseline score of 1.76 ± 0.24.Conclusions:The results of this study indicate that oral hygiene of orphans was improved using a peer group approach model of oral health promotion.
