the rationale underlying treatment recommendations based on esthetic impairment come from the social science researches , which indicate that unacceptable dental appearance may stigmatize , impede career advancement and peer group acceptance , encourage negative stereotyping , and have a negative effect on self - concept .
orthodontic problems are usually not associated with grave mortality or morbidity ; hence , they tend to be overlooked by most health professionals as less important .
however , studies reveal that malocclusions have a significant impact on the psychosocial health of the affected individual . for many years
, epidemiologic studies of malocclusion suffered from considerable disagreement among investigators , especially regarding how much deviation from the ideal should be accepted within the bounds of normal .
the orthodontic treatment need in the study group was assessed by esthetic component ( ac ) of the index of orthodontic treatment need ( iotn ) .
it is being widely used in dental epidemiology to prioritize orthodontic treatment and seeks to quantify the likely sociopsychological effects of each patient 's malocclusion .
the study was undertaken to assess the orthodontic treatment need in 2025-year - old patients reporting to the department of orthodontics and dentofacial orthopaedics , as assessed by orthodontists to plan future orthodontic services in the region as per priority in orthodontic triage , for worldwide comparisons , and as a powerful tool for patient counseling .

the sample comprised 753 patients ( 360 females and 393 males - table 1 ) irrespective of gender , caste , creed , and socioeconomic status essentially fulfilling the following criteria : 
 2025 years old [ table 2 ] 
 no history of previous / current orthodontic treatmentpresence of all permanent teeth with / without third molarsno large restorationsinformed consent from patients for participation as part of the survey . 
 
2025 years old [ table 2 ] 
  no history of previous / current orthodontic treatment presence of all permanent teeth with / without third molars no large restorations informed consent from patients for participation as part of the survey .
the division of sample according to gender division of the subpopulation according to the age patients were examined clinically using mouth mirror and explorer .
ac was assessed by comparing and matching digitally clicked intraoral frontal view photograph in occlusion to the nearest resemblance on standardized photographs of iotn .
number 1 is the most , and 10 , the least attractive arrangement of teeth .
the anterior teeth were graded in their dental attractiveness as seen and no endeavor was made to predict the future appearance of the dentition .
esthetic component of the index of orthodontic treatment need scale ( photographs 110 ) the ac of iotn has commonly been used to evaluate the treatment need on esthetic grounds by dentists ( operator - rated ) or patients ( self - rated ) .
both patients and orthodontists can also assess the ac with the intent of removing the influence of parents and patients desires on the assessment of treatment need apart from considering individual variations in psychological maturity .
esthetic component grades all the data were analyzed using the statistical package for the social sciences 13.0 software program , ibm corporation , new york , usa . results of the ac revealed that 78.1% exhibited no or slight need for treatment , whereas 13.2% demonstrated moderate to borderline need , and only 8.7% proved to have a definite need for orthodontic treatment .
this states that the examiner , in general , expressed satisfaction with the esthetics of most of the screened patients , like the one shown in figure 2 unlike the one in figure 3 that without doubt required treatment . a patient categorized with slight need for orthodontic treatment a patient in severe / definite need for orthodontic treatment

malocclusions may range from the severe , rather uncommon conditions such as cleft lip and palate to the more common irregularities of teeth resulting from biological variations .
management of malocclusion is contained by a number of disciplines in dentistry , primarily orthodontics and attempts to prioritize treatment have used the measure of iotn , which relates to treatment need rather than its complexity .
a sample of 753 patients from among those reporting to the department for a routine dental check - up was considered .
the age group of 2025 years old was chosen because by then , the patients would be in a permanent dentition stage . at this age , there are less individual variations in dental age and occlusal development .
the ac scores were recorded by the orthodontist unlike other studies where the patients self - assessed with the intent of removing the influence of patients desires on the assessment of treatment need apart from considering individual variations in psychological maturity .
78.1% exhibited no or slight need for treatment , whereas 13.2% demonstrated moderate to borderline need , and 8.7% proved to have a definite need for orthodontic treatment [ figures 4 and 5 ] .
esthetic component scores inference of esthetic component grading in evaluating the ac in a sample population in shiraz , 91.3% of the population was in no need for treatment , 2.44% in moderate need , and 6.21% in great need for treatment . on the contrary ,
22.8% of the malaysian children were found to have a definite need according to ac in a study conducted by abdullah and rock in 2001 .
analysis of registrations of the ac of the iotn should be interpreted with some caution .
it has shortcomings , for example , the lack of photographs showing hypodontia , anterior spacing , and a class ii division 2 dentition .
there is always some uncertainty in assessing the photographs of different types of malocclusion to identify one which corresponds to one 's own dental appearance .
kok et al . , ( 2004 ) suggested that concern about a malocclusion is not closely related to the severity of the malocclusion in terms of esthetics as measured by the iotn - ac .
2002 suggested that the 10 photographs should be complemented with photographs of patients from other ethnic backgrounds .
these studies not only provide a global perspective of high orthodontic treatment need , but also confirm a persistently high orthodontic treatment need over the past decade
. in some european countries , general dentists and orthodontists have been using indices of treatment need to prioritize state - funded orthodontic treatment for children with major irregularities .
in addition , the demand for orthodontic treatment has increased in contemporary setting due to increasing awareness and perceptions resulting in extensive waiting rolls .
it is essential , therefore , that health authorities should carefully prioritize and plan the provision of orthodontic treatment . the introductions of easily comprehensible , reproducible , valid , and reliable indices of therapeutic need such as the ac of iotn have allowed improved focusing of services

 a baseline data were obtained for planning future orthodontic services in the region as per priority in orthodontic triage .
the data collected can help for worldwide comparisons with other populationsthe ac - iotn is , hence , being used as a powerful tool for patient counseling and planning desired orthodontic mechanotherapy in the department .

 aim of the study : the purpose was to assess orthodontic treatment need in a subpopulation as assessed by the orthodontists.materials and methods : the study was conducted on a sample population of 753 patients aged 2025 years to assess the need for orthodontic treatment using the esthetic component ( ac ) of the index of orthodontic treatment need ( iotn).results : the ac revealed that 78.1% of the sample exhibited no or slight need for treatment , 13.2% demonstrated moderate to borderline need , and 8.7% proved to have a definite need for orthodontic treatment.conclusions:the ac - iotn can definitely be considered to be used as a powerful tool for prioritizing orthodontic triage , patient counseling , and planning desired orthodontic mechanotherapy .
