Aim: Purpose of our research is to study the release of nickel as well as chromium ions from orthodontic wires in patients who are using teeth whitening mouthwashes.Methodology: In vitro, experimental study was carried out on 50 orthodontic wires of same length of SS, and NiTi. The samples were immersed in Oral B and Listerine (20 each) for 1, 6, 24, and 168 h. 10 samples immersed in distilled water served as the control group. Atomic absorption spectroscopy served to compute the number of released ions.Results: Nickel ions were released from both wires at all time-points; the highest amount was in Listerine and the lowest in Oral B mouthwashes. The process of release of chromium from the SS wire was the same as that of nickel. However, the release trend in NiTi wires was not uniform.Conclusion: Listerine caused the highest release of ions. Oral B showed the lowest amount of ion release.

Aim: Purpose of the study was to judge the prevalence of malocclusion and associated predisposing deleterious oral habits in South Indian teen population. Methodology: Prevalence of malocclusion and treatment need was assessed using the Dental Aesthetic Index (DAI) among a sample of 1000, 12 and 15-year-old school children in prominent South Indian cities, who received no treatment before or during the study. Subjects were also assessed for deleterious oral habits. For statistical analysis, Chi-square test was wont to test the correlation of habits with mean DAI score and malocclusion traits. Results: Mean DAI score was 26.81±5.25. Nearly 52% of the study sample presented with malocclusion, starting from ‘definite’ to ‘handicapping’ supported the DAI scores. The prevalence of varied deleterious oral habits was 21.2%. About 35% of youngsters with any oral habit developed malocclusion as compared to those with none habit (P value=0.014). Tongue thrusting, mouth breathing and thumb sucking habits had a major impact on malocclusion.Conclusion: It was evident from the results of our study that presence of malocclusion directly depends upon the presence of deleterious oral habits in general.
