STUDY TO KNOW THE ORTHODONTIC TREATMENT, NEED AND PRETREATMENT COMPLEXITY

Although work has been done in Pakistan to determine the orthodontic treatment need of patients, but still it is required to evaluate the orthodontic pretreatment complexity. A newer occlusal index; Index of Complexity, Outcome and Need (ICON) was used on a sample of 100 pretreatment study casts of the patients. Place of Study: Dental Department, Mayo Hospital Lahore, Pakistan. Study Duration: Six month. From July 2018 to December 2018. To evaluate the need for orthodontic treatment and orthodontic pretreatment complexity grade. The data was statistically analyzed by SPSS (8.0). Overall it was found that 87% of the cases needed some sort of orthodontic treatment. 85.3 % of female patients and 92% of male patients needed treatment. More than 60% of the patients were classified as being difficult and very difficult to treat, with 34% in the very difficult to treat group. Aesthetic Component grade 8 was shown by 26% of cases. 51% had cross bite and more than 40% were having cusp-to-cusp interdigitation in the posterior segments. Results of the study showed, a high number of patients in need of the orthodontic treatment and also concluded that most of the patients undergoing treatment at the orthodontics department are difficult to treat. Key words: Occlusal indices, orthodontic treatment, pretreatment, complexity grad
