Abstract
In this study two commonly used and conceptually different measures of indices were used in assessing the severity and treatment need on Coimbatore population. This study appears to be the first study to examine the impact of malocclusion and its treatment need on patients who reported to our Orthodontic department. 1. In our study, the Coimbatore population showed 17% requires no need of treatment, 30% requires moderate need of treatment and 53% requires greater need of treatment when DHC of IOTN was used. 2. On the other hand, the Aesthetic component showed 25.5% showed no need of treatment, 63.5% moderate level of treatment needed and the great need of treatment was about only 11%. 3. When OI was used, our study population showed 22%no need of treatment, 45% requires moderate need of treatment and the great need treatment was about 33%. 4. The study shows, the prevalence for severity of malocclusion was assessed and found to be equally distributed with no gender differences. 5. In the present study, the OI correlated better with objective assessment of IOTN -DHC and subjective opinion of IOTN-AC. Between DHC & AC of IOTN there was poor correlation. 6. We found poor correlation between objective and subjective assessment for both severity & treatment need with in DHC & AC of IOTN, indicating that the need for treatment differs from patients perspective. 7. The need for orthodontic treatment was higher and most of the samples were in the category of moderate to great treatment needed, which is almost equal to the percentage values found by Brook and Shaw and It would be useful to replicate this study in other settings to support or refute our present findings. To conclude, the present study done on Coimbatore population indicated a high prevalence of malocclusion in terms of severity & treatment need. The study also established a reliable base line data regarding prevalence, distribution and severity of malocclusion to meet the treatment needs in our population .In India with a vast ethnic and cultural heritage, where there is a wide range of prevalence of malocclusion, further epidemiological studies of this nature is needed to analyze the demand for orthodontic treatment.
