Assessment of orthodontic treatment need among school children by using iotn (index of orthodontic treatment need)

Abstract

INTRODUCTION. Dental treatment is carried out in order to improve dentofacial аesthetic, function and health of patient. Aesthetic is the main reason for treatment, therefore we have to decide which aesthetic norms should we follow when we are planning orthodontic treatment. Although no consensus was reached for individual and occlusal features that need to be assessed in order to ascertain the orthodontic treatment need. In modern literature are using multiple indices to improve treatment planning. One of these indices is IOTN (Index of Orthodontic treatment need), described by Brook and Shaw (1989) and amended by Richmond (1990) as a method to objectively assess the orthodontic treatment need.

AIM. This index is used to assess patient eligibility for orthodontic treatment.

MATERIAL AND METHOD. Examinees aged 12-16 years of both sexes occurred in the orthodontic practice with a desire to be treated. Each of them were given a questionnaire filled out before completing the clinical examination. Normative orthodontic treatment need was assessed clinically using IOTN index.

RESULTS. 70% of examinees thought it definitely need orthodontic treatment, and 30% of them think that probably yes. In 60% of them, the irregularities of the teeth noticed parents, 40% irregularities them into notes their dentist. 60% of respondents were previously orthodontic treatment, while 40% of them never previously had orthodontic treatment.

CONCLUSION. A significant difference was found between our assessment and self-assessment of the examinees in the attractiveness of their occlusion. For effective orthodontic treatment, in addition to professional evaluate it, subjective perception must be taken into consideration when formulating a treatment plan in order to ensure a final product that will satisfy expectations of the patient.
