  Introduction Top


Health is a state of total effective physiologic and psychological functioning, which has both a relative and an absolute meaning. Oral health is an integral part of general health. Dento facial appearances that deviate from the social norms may have a negative impact on social, physiological and psychological functions. Malocclusion may lead to such deviations and if left untreated may lead to various health problems like difficulty in speech, difficulty in eating and swallowing, hampered esthetics and psychological distress.

At the same time, most of the malocclusions can be corrected if detected earlier by correctional methods. As malocclusion is considered to be public health problem. [1] The prevalence of occlusal anomalies, the need for orthodontic treatment should be ascertained with a given community, so that appropriate arrangements could be made for allocation of staff and financial resources.

Malocclusion may be detected at early years of life, but malocclusion occurring during mixed dentition period may sometime be transitional and hence do not give the true picture of the prevalence in the community. Hence, children aged 12-15 years are suitable for early detection of types and extent of malocclusion. [2],[3],[4] Interceptive and sometimes corrective treatment is recommended at this age group as all permanent teeth have erupted, and the maxillae will be in the active growth period. The present study is focused on determining the prevalence of malocclusion and the need for orthodontic treatment among 12-15 years school children of Ambala district, Haryana.

Aims and objective

  • To assess the prevalence of malocclusion and the need for orthodontic treatment among 12-15 years school children of Ambala district, Haryana
  • To assess knowledge and attitude of students, regarding malocclusion and also to assess the felt barriers for correctional orthodontic treatment.



  Materials and Methods Top


The present study was carried out in the district Ambala, which is comprised of three tehsils. In the beginning, an adequate sample size was estimated based on the results of the pilot study and previous studies. Before the start of the study, a list of all schools was obtained from the district education office. The study was done in the government schools. The total numbers of government high schools in Ambala were 86. The entire district was divided into six blocks, and a multi-stage random sampling technique was adopted for schools and from the selected schools a universal sample was taken.

Inclusion criteria

All children between 12 and 15 years were included. [2],[3],[4] This age group is included in the study because most of the malocclusion becomes fully visible by this age, and this is the age where it can be easily and effectively corrected by interceptive or corrective orthodontic treatment.

Exclusion criteria

  1. All children below and above the mentioned age
  2. Children already undergoing correctional orthodontic treatment.


The examiner was trained and calibrated for dental esthetic index (DAI) in the department by the department staff. Type III examination [5] was carried out in the school premises. The children were allowed to sit on a chair or stool as per availability. A table to place instruments was placed within easy reach of the examiner. Data were collected on a modified WHO oral health assessment form 1997. [6] The assessment of malocclusion was done according to DAI. DAI was proposed by Cons et al. as an objective index concentrating on the correlation between occlusal morphology and socio-psychological handicaps, in the year 1986. The DAI also tells us about the severity of malocclusion and the treatment needs. The scoring was done using a community periodontal probe. [6],[7]

The data obtained were analyzed using SPSS package version 10. Differences were tested for statistical significance by using the Chi-square test, Mann-Whitney test, post hoc test and ANOVA probability tests. P < 0.05 was considered as statistically significant and P < 0.001 was considered as highly significant.


  Result and Discussion Top


As DAI is a ten point index, each criterion was examined and assessed. [8],[9] In females, 64.1% (706) had no spacing, 26.2% (289) had one segment spacing, and 9.6% (106) had two segment spacing. In males, 62.4% (518) had no spacing, 23.1% (192) had one segment spacing, and 14.5% (120) had two segment spacing. Incisal segment spacing was highly significant between male and females (P = 0.003). This could be attributed to the jaw size discrepancy between the genders. Apart from this all the other parameters were nonsignificant.

Age and sex wise distribution of DAI scores and shows that in males DAI score was 26.2 and in females it was 25.7 which is not significant. In 12 years old, the mean DAI was 27.5, in 13 years old it was 26.5, in 14 years old 25.3 and in 15 years old 24.9 [Table 1]. The results were not significant.

In the present study, the mean DAI was 25.95, which states that the majority of the population screened had a definite malocclusion. It is in correlation with study by Bernabé and Flores-Mir [10] with DAI score 28.8, Katoh et al. [11] study in Taiwan with DAI score 25.9 and Jenny et al. [8] with DAI score of 26.53. In a study done by Ansai et al. [7] the score was a little higher 30.5. This little difference in mean DAI score may be due to the reason that these studies were done in different countries that could be attributed to racial differences.

Males had a slightly higher DAI score (26.2) than females (25.7) in the present study [Table 2]. Similar results were obtained by Otuyemi et al., [12] with mean DAI score 22.61 ± 5.87 (males) and 22.1 ± 5.79 (females). Thus, the difference in DAI score was nonsignificant. Marques et al. [13] also concluded to have no significant difference between DAI scores of males and females.

In the present study 53.6% of children did not require any treatment, 24.3% required elective treatment, in 12.4% the treatment was highly desirable and in 9.8% it was mandatory [Table 3]. Similar results were found by Marques et al., [13] Jenny and Cons [14] and Abdullah and Rock. [15] But contrary to these results Otuyemi and Noar [16] and Onyeaso [17] showed that the percentage of the population with handicapping malocclusion was quite high. The reason could be because it was a hospital based study and hence the majority of subjects were those who reported for orthodontic treatment and in the study by Onyeaso, [17] the study population was mentally challenged who generally have developmental anomalies and thus severe malocclusion.

Regarding the knowledge and attitude some questions were asked to the subjects. [18] 33.3% of males and 30.3% of females were conscious about their malocclusion and knew that their teeth were irregular. However, the fact that malocclusion affected their esthetics was known by 42.2% of males and 45.2% females.

The knowledge that a dentist can correct the irregular teeth was known by 68.4% males and 69.3% females. However, the motivation to get their teeth corrected was only in 59.4% males and 58.5% females.

Only 40% of males and 33% females knew about the dental college in the vicinity. Even if they knew about the college, only 37.5% males and 30.9% females knew that orthodontic correctional treatment is also available at this college. The knowledge of parents about the orthodontic treatment was negligible as only 20.7% of boys said that their parents know about the treatment and 25% girls said the same. 31.1% (258) of males and 31.2% (344) females said that the cause for not coming for correctional care was lack of finances. 9.5% (79) of males and 10.4% (114) of females said that the barrier perceived was that they could not come for treatment during the school hours as the school timing unfortunately coincided with the college timing.


  Conclusion Top


There is a high prevalence of orthodontic need among 12-15 years high school students according to DAI. There is a considerable amount of deficiency of knowledge and awareness among students and parents about correctional orthodontic treatment. The major barrier perceived through my study about orthodontic care was lack of knowledge, understanding and awareness regarding existing irregularity of teeth, lack of awareness regarding existing dental health care facility in the nearby vicinity, lack of perception of the parents regarding their children's irregular teeth and lack of finances.


  Recommendation Top


  1. There is a need for school health education program for creating awareness and knowledge about general health, oral health and self-assessment of irregular teeth and correctional facilities available
  2. Strategies should be thought of rendering preventive and correctional orthodontic treatment for the economically weaker section of the students who are studying in government schools.
