ABSTRACT
Bolton introduced the anterior and overall ratios that must exist between maxillary and mandibular teeth so as to obtain optimum occlusion. This study was conducted for the purpose of establishing the mean Overall Ratio [OR] and Anterior Ratio [AR] of the Bolton Analysis and the presence of Tooth size discrepancy [TSD] outside 2SD of the Boltoris mean in an orthodontic population, irrespective of -the type of malocclusion. The sample comprised 180pre treatment study casts with fully erupted and complete permanent dentitions from first molar to first molar. Selected randomly from records of the orthodontic patients. The mesiodistal diameters of the teeth were measured at contact points using digital calipers and the Bolton's analysis was carried out. The prevalence of tooth size discrepancies [TSDs] outside of 2 Standard Deviation [SD] from Bolton's mean were 18.8% for the overall ratio and 51% for the anterior ratio. Bolton tooth-size discrepancy is found in large number of Pakistani orthodontic patients which may effect orthodontic treatment goals and outcome. Thus, our results o support that Bolton analysis should be mandatory for every orthodontic case before starting the treatment
ABSTRACT
The objective of this study was to compare the orthodontic treatment need among male and female patients attending Islamic International Dental Hospital, Islamabad [I.I.D.H]. Different studies had been conducted to determine the orthodontic treatment need in Pakistan but so far no individual study had been done to compare orthodontic treatment need on basis of gender. Index of Orthodontic Treatment Need [IOTN] was used on a sample of 200 patients [100 male, 100 female] at Islamic International Dental Hospital, Islamabad Pakistan, to evaluate the need for orthodontic treatment. Using SPSS version 10.0 data was analyzed. Result showed that 36% of female patients and 41% of male patients needed definite orthodontic treatment according to DHC whereas 12.5% of female patients and 23.5% of male patients were needed definite orthodontic treatment according to AC. Greater percentage of males was found in definite treatment need than females [p =0.005] according to AC whereas DHC showed insignificant difference among males and females for definite treatment need [p =0.133]

The objective of this study is to compare the orthodontic treatment need among male and female patients attending Islamic International Dental Hospital, Islamabad [IIDH]. Across-sectional study. Ten months from September 2007 to July 2008 at Islamic International Dental College. Index of Orthodontic Treatment Need 10TN] was used on a sample of 200 patients [100 male, 100 female] at Islamic International Dental Hospital, Islamabad Pakistan, to evaluate the need for orthodontic treatment. Using SPSS version 10.0 data was analyzed. Result showed that 36% of female patients and 41% of male patients needed definite orthodontic treatment according to Dental Health Component [DHC] whereas 12.5% female patients and 23.5% male patients were needed definite orthodontic treatment according to Aesthetic Component [AC]. According to AC greater percentage of males was found in definite treatment need than females [p =0.005], whereas DHC showed insignificant difference among males and females for definite treatment need [p =0.133]. According to AC, there is more need of treatment for males than females. Whereas according to DHC there is no significant difference between males and females in treatment need
ABSTRACT
To evaluate the orthodontic treatment need a study was conducted at orthodontic department of Islamic International Dental Hospital [IIDH]. Index of Orthodontic Treatment Need [IOTN] was applied in a sample of 300 patients. Data was analyzed using SPSS version 10.0. Out of 300 subjects 114 were males and 186 females with mean age of 18 +/- 4.8 years were reported. Dental Health Component showed 19% [Grade 5], 57% [Grade 4], 18% [Grade 3], 5% [Grade 2] and 2% [Grade1] results respectively and Aesthetic Component showed percentages as 31.66% [Scale 1-4], 32% [Scale 5-7] and 36.3% [Scale 8-10]. Strong association was found between aesthetic component and dental health component [p=.000]. According to Dental Health Component 75% of the population was found to be in definite treatment need and only 36.3% of the population was in definite treatment need according to Aesthetic Component. No significant gender difference was found for treatment need
