Orthodontic Treatment Need at Nishter Institute of Dentistry

Background: The Index of Orthodontic Treatment Need (IOTN) is one of the important index to find out orthodontic need of patients. Aim: To find out the need of orthodontic treatment in patients visiting Nishter Institute of Dentistry, Multan (NID). Method: The index was applied using plaster models and intraoral examination. The measurements of various components of IOTN index was taken with the help of digital vernier calliper. Results: The results of various measurements of IOTN index was taken, recorded and analyzed statistically. Result of the present cross-sectional study showed that 65% patients were in grade 4 and 5 of IOTN. The analysis showed that 13% were in grade 4 of IOTN, 52% were in grade 5, 15% were in grade 3, 16% were in grade 2 and 4% patients was in grade 1 of IOTN index. Conclusion: No significant sex differences were shown for the need of orthodontic therapy in any category of IOTN. The need of orthodontic treatment is very high in patients of Southern Punjab, Pakistan. Keywords: Treatment Need; IOTN; Orthodontics.

PLATOON: Premature Loss of bAby Teeth and its impact On Orthodontic Need - protocol

Objective: To investigate the impact of premature extraction of primary teeth (PEPT) on orthodontic treatment need in a cohort of children participating in the Born in Bradford (BiB) longitudinal birth cohort. Design: Observational, cross-sectional cohort. Participants: We aim to recruit 1000 children aged 7–11 years: 500 with a history of PEPT and 500 matched non-PEPT controls. Methods: After informed consent/assent, orthodontic records will be collected, including extra and intra-oral photographs and alginate impressions for study models. Participants will also complete a measure of oral health-related quality of life (COHIP-SF 19). The records will be used to quantify space loss, identify other occlusal anomalies and assess orthodontic treatment need using the Index of Orthodontic Treatment Need. For each outcome, summary statistics will be calculated and the data for children with and without PEPT compared. The records of the children identified to be in need of orthodontic treatment will be examined by an expert orthodontic panel to judge if this treatment should be undertaken at the time of the records or delayed until the early permanent dentition. Collecting robust records in the mixed dentition provides the clinical basis to link each stage of the causal chain and enable the impact of PEPT on orthodontic need to be characterised. This study is the first to provide the foundations for future longitudinal data collection allowing the long-term impact of PEPT to be studied.

Orthodontic Treatment Need in 11-13 Years Old Shoolchildren in Republika Srpska

SUMMARY Introduction Need for orthodontic treatment is determined by the severity of specific malocclusion. Orthodontic indices are used to objectively present treatment needs. The most commonly used is the Index of Orthodontic Treatment Need (IOTN). The aim of this study was to determine the need for orthodontic therapy in 11 to 13 years old schoolchildren in Republika Srpska. Material and Methods 1377 patients, 11 to 13 years old, were included in this study. The examinations were performed in elementary schools, using daylight, flat mirror and two-dimensional orthodontic caliper. Patients were ranked into 5 grades according to the Dental Health Component (DHC) and graded on a scale 1 to 10 for the Aesthetic Component (AC) of the IOTN index. Results According to the Dental Health Component (DHC), 79.23% of patients needed orthodontic treatment. Little and borderline orthodontic need was present in 27.74% and 24.83% children, respectively, while severe need was present in 19.98% and 6.68% respectively. 20.77% of subjects did not need orthodontic treatment. In regards to the Aesthetic Component (AC) (face appearance related to orthodontic need) little or no treatment was needed in 91.42% of subjects while 6.42% were borderline and 2.16% of subjects had severe relation between orthodontic need and facial appearance. Conclusion Due to the wide presence of orthodontic irregularities in schoolchildren 11-13 years old in Republika Srpska, it is important to introduce orthodontic indices in clinical practice in order to determine orthodontic treatment needs.
