Background: Different indices have been used to determine orthodontic treatment needs such as the Dental Aesthetic Index (DAI) and the index of orthodontic treatment needs (IOTN).
Objectives: The present study was carried on to compare the dental aesthetic index (DAI) and the IOTN’s dental health component (DHC) in assessment of orthodontic treatment needs of 11 - 14 year old schoolchildren in Qazvin.
Methods: In a cross-sectional descriptive study, 250 of 11 - 14 year old schoolchildren from two school districts of Qazvin were selected by a two-stage stratified cluster sampling method and their AC scores were determined according to the orthodontist and child’s own idea. Also the subjects’ DHC and DAI scores were determined according to the existing standards. The patients’ demographic data were recorded by means of a questionnaire and correlations between AC’s as determined by the subject and by the orthodontist, as well as scores of the DHC and the DAI, were analyzed using Spearman correlation ratio. Results: The mean of AC score as determined by the subject was 2.556, while the scores by the orthodontist were 4.308; while DHC score was 2.60 and DAI score was 26.86. The coefficient of correlation between students and specialist AC, students AC and DAI, specialist AC and DHC, specialist AC and the DAI,DHC and the DAI, students AC and DHC was respectively 0.269, 0.262, 0.549, 0.506,0.794(In all cases P < 0.0001) and 0.202 (P < 0.001).
Conclusions: Existence of a positive and significant relationship between the AC, the DHC and the DAI indicates their potential for determining the need for orthodontic treatment. The highest need for orthodontic treatment was determined by the AC of the specialist and the lowest need by that of the patient. Only gender of the student had a significant effect on the values of the DHC and the DAI as determined by the specialist.

Aim: Assessment of patient's motivations requesting orthodontic treatment can help clinicians in meeting the needs and expectations of patients and attain a successful treatment result.Objective: The present study was carried out in 2008 to provide data regarding motives of patients coming to specialized orthodontic clinics of Qazvin for treatment.Materials and Methods: In this descriptive study, 300 patients aged 12 years old and more (27.3% males, 72.7% females, the mean age: 19.61 years) were studied. Age, gender, parents’ level of education, and father’s occupation, motives for improving teeth and face components; and the location of pain and discomfort were evaluated. The correlation between motives and different socioeconomic factors were assessed using Spearman and Pearson correlation coefficients.
Results: Alignment of the anterior teeth was the most frequent motive regarding the teeth (89.3%). However, for face components ,it was improving teeth and gingival view during smiling (18.7%). Significant correlations were noted between patients' gender and motivation to align anterior teeth (p<0.009), movement of the lip (p<0.01), change of the nose length (p<0.002) and position (p<0.03) while females had higher motivation for these changes. As mothers’ level of education increased, the motivation to change the height of anterior teeth (p<0.03), improving the teeth and gingival appearance during smiling (p<0.001), decreasing the lip or chin tension in the closure of the lips (p<0.05) and decreasing the prominence or width of the mandible toward the mouth (p<0.01) decreased significantly. Conclusion: Alignment of anterior teeth and improving the teeth or gingival appearance during smiling were found to be major motives for requesting orthodontic treatments.

Aim: Occlusal indices used to determine orthodontic treatment needs cannot include the patients’ perception about their need for orthodontic treatment. That is why in some cases, these indices show that a particular patient needs orthodontic treatment while the patient feels no such need. This study was carried out to compare normative and self-perceived orthodontic treatment needs of 11-14 year-old school children.Materials and Methods: In a descriptive cross-sectional study 250 children of 11 to 14 years old were selected randomly. The scores of the Aesthetic Component (AC) of IOTN, were determined by specialist and the children themselves. The Dental Health Component (DHC) of IOTN was also assessed. Statistical analysis used: correlations between the AC of the patient, AC of the specialist and DHC of the specialist were assessed using Spearman’s rho correlation coefficient.
Results: The mean of patient’s AC and specialist’s AC were 2.556 and 4.308, respectively, while the mean of specialist’s DHC was 2.60. The correlation coefficient between patient’s AC and specialist’s AC was 0.281, between specialist’s AC and DHC was0.549 and between patient’s AC and DHC was 0.210. The highest correlation was seen between specialist’s AC and DHC and the lowest correlation was seen between patient’s AC and DHC.Conclusion: The significant positive relation between the AC indices and the DHC indicates their ability to determine the need for orthodontic treatment. The highest need for orthodontic treatment was determined by specialist’s AC and the lowest was patient’s AC.

Aim: One of the core parts of clinical orthodontics is the analysis of dentofacial growth. Changes that occur in the shape, form and size of dentoalveolar arch may result in various problems during diagnosis and treatment planning. The aim of this study was to investigate the late changes of alignment in the anterior teeth of mandible during 4-years follow up in young adults with normal occlusion in QazvinMaterials and Methods: This was a longitudinal descriptive survey with 23 samples (13 girls and 10 boys). Subjects with an age range of 13±1 were selected for dentoalveolar change assessment. Two dental models were prepared from each subject one at the start of the investigation and one at the 4 years follow up; photographs of each model were taken at the time. Inter-canine distance, anterior arch depth, arch shape index, anterior teeth width (6 anterior teeth), anterior arch circumference (ATSALD) were measured using AutoCAD 2004 software and digital caliper. Means and standard deviations were measured using Npar test analysis. Data were compared at 0 and 4 years and between two genders using Wilcoxon test (P<0.05).Results: The most prevalent changes in samples belonged to ATSALD (2.2mm increase) over the four years. The least changes were detected in arch shape index. Anterior arch circumference and ATSALD were the dominant changes in boys and girls, respectively.Conclusion: During this critical growth period, anterior crowding of mandibular teeth increases in both boys and girls, while the inter-canine distance and arch shape index decrease.
