The Prevalence of Malocclusion and Orthodontic Treatment Need in 13-15 Years Old School Going Children of Mehsana District, Gujarat: An Epidemiological Study.

The current study's objective was to find out the prevalence of malocclusion and the need for orthodontic treatment in 13- to 15-year-old school students in the Mehsana District of Gujarat using the IOTN. A descriptive cross-sectional epidemiological survey was planned among 13- to 15-year-old school-going children of Mehsana district. The sample comprised of 1290 school children. DHC-IOTN was applied to evaluate normative need for orthodontic treatment. Perceived orthodontic treatment was described by the Aesthetic component of the IOTN index. Results showed that 33.7 percent of participants required little/no treatment need, 43.9 percent of participants required moderate orthodontic treatment need, and 22.4 percent of participants required severe orthodontic treatment need in the district. To prepare for public orthodontic and dental services, the current study provides baseline data on the need for orthodontic treatment among school-aged children.

Relationship of 3 indexes of orthodontic treatment need used by Medicaid and oral health–related quality of life

This study aimed to assess the relationship between 3 indexes of orthodontic treatment need that are used by Medicaid, namely the Salzmann Index (SI), the handicapping labiolingual deviation (HLD) Index, and the HLD California Modification Index, and oral health-related quality of life (OHRQOL). The orthodontic records of 100 participants aged 11-14 years were used to calculate occlusal index scores. The condition-specific oral impacts on daily performances (OIDP) index questionnaire was used to quantify OHRQOL and to identify detriments attributable to malocclusion-related conditions (MRCs). The relationship between occlusal index scores and OHRQOL was analyzed using descriptive statistics, Spearman rank-order and biserial correlations, and logistic regression. The mean index scores were: SI, 15.4; HLD, 13.2; and HLD California Modification, 15.8. Ninety percent of participants did not have normative orthodontic treatment need according to current index criteria. OIDP scores were not normally distributed, and the mean score was 3.1. Of those participants who reported an impact, 83% attributed at least 1 of those impacts to MRCs; however, 90% of these were of mild or moderate intensity. Smiling was the performance most impacted by MRCs. The only statistically significant correlation between an occlusal index and OIDP scores was for the SI, though this association was weak (r= 0.27). None of the variables used in the logistic regression model (age, sex, 3 index scores) were significant predictors of OHRQOL. No meaningful association exists between the 3 indexes studied and OHRQOL. These findings challenge the validity of current systems for the allocation of Medicaid-funded orthodontic treatment.

Orthodontic treatment need and perception: A comparative study between different socio-economic groups of patients

Objectives: The aim of the present study was to compare parents’ perceptions of their children’s malocclusion and clinician-measured normative orthodontic treatment need with the socioeconomic status of the parents as a means of assessing whether demand for treatment is uniform across socioeconomic groups. Material and Methods: In this cross-sectional study, 212 (125 girls and 87 boys) subjects between the ages of 8 and 25 years (mean age 17.03 ± 3.9) were assessed. The parents were asked to score the dental attractiveness of their children and their socioeconomic status (SES) based on the aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN) and the modified Kuppuswamy scale (2018), respectively. The subjects recorded their self-perception using the OASIS scale. These scores were then compared within themselves and with those of the clinician who also scored the Dental Health Component (DHC) and AC of the IOTN. The AC grade of the IOTN and parents’ SES was tested with the Chi-square test. The association between the AC scores of the IOTN, DHC, and the characteristics of the subjects was tested with Spearman’s correlation coefficient (rho). Results: Treatment uptake was uniform throughout the different socioeconomic groups. Association between the SES group and DHC group and clinician-measured AC were statistically not significant (P = 0.3958), (P = 0.3447). Parents, in this study population, irrespective of their socioeconomic status rated their children’s orthodontic treatment need less severely than the clinician (P = 0.0001). Severity of malocclusion as measured by DHC was much higher in male subjects than in females (P = 0.0348). Conclusion: Socioeconomic status of the parents did not seem to affect their perception of dental appearance. Self-perception of appearance and perceived treatment need was uniform throughout the different socioeconomic groups.

Can orthodontic need cause bullying?

ABSTRACT Objective: To determine the association between orthodontic treatment need and the self-reported bullying, and its impact on adolescents’ self-esteem. Methods: The sample consisted of 160 schoolchildren from 11 to 14 years of age, enrolled in public schools. The history of bullying was evaluated by means of the Crozier; Dimmock adapted Questionnaire (1999). Self-esteem was determined by means of the Global Negative Self-Evaluation Scale (GSE). The normative orthodontic treatment need was determined by the Dental Health Component (DHC) and perceived need, by Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN). Individual analyses were made of the associations with the history of bullying (outcome). Results: The variables that presented P ? 0.20 in the individual analyses were tested in a multiple logistic regression model, and variables with P ? 0.05 remained in the model. The odds ratios with the intervals of confidence were estimated. According to the results 72.5% of the schoolchildren reported a history of bullying. The schoolchildren who presented negative impact on the quality of life related to oral symptoms and negative self-esteem were observed to have 4.59 and 5.44 times more chance, respectively to report a history of bullying (P < 0.05), which did not suffer the influence of normative and perceived orthodontic treatment need. Conclusion: The history of bullying was not influenced by orthodontic treatment need, but by the low self-esteem of adolescents.

Relationship between the Normative Need for Orthodontic Treatment and Oral Health in Mexican Adolescents Aged 13-15 Years Old.

This cross-sectional study aimed to establish a relationship between the Normative Need for Orthodontic Treatment (NNOT) and oral health among Mexican adolescents aged 13–15 years old. A convenience sample of 424 subjects in Mexico City participated in the study. The dependent variable used was NNOT, which was determined via the dental health component (grades 4 and 5) of the Index of Orthodontic Treatment Need (IOTN). The variables for oral health were as follows: caries experience, oral hygiene, self-reported temporomandibular joint pain, and self-reported bruxism. Logistic regression models were fitted to determine the association between NNOT and oral health. The prevalence of NNOT was 66.0% (280/424), and the crowding was the most prevalent occlusal anomaly with 36.1% (n = 135). Multivariate models showed that subjects with NNOT were more than twice as likely to present poor hygiene (OR = 2.56; p = 0.001) as subjects presenting crowding (>4 mm) (OR = 1.99; p = 0.004) and increased overjet (>6 mm) (OR = 1.74; p = 0.046). Those schoolchildren who presented anterior guidance were 72% less likely to present NNOT (OR = 0.28; p < 0.001). In conclusion, the risk of presenting NNOT in Mexican adolescents is high, with a prevalence of over 50% of which the most prevalent occlusal anomaly was crowding. On the other hand, poor oral hygiene was associated with crowding and increased overjet.

How is orthodontic treatment need associated with perceived esthetic impact of malocclusion in adolescents?

The purpose of this research was to evaluate the esthetic impact of orthodontic treatment need in adolescents. This cross-sectional study was performed with 1172 adolescents aged 12 (n=638) years and 15 (n=534) years from Salvador, Bahia, Brazil. The esthetic impact was the following outcome variables: Aesthetic Component of the Index of Orthodontic Treatment Need and the Oral Aesthetic Subjective Impact Scale. The normative orthodontic treatment need was assessed by the Dental Health Component of the Index of Orthodontic Treatment Need (IOTN-DHC) and by the Dental Aesthetic Index (DAI). Logistic regression models were adjusted, estimating crude odds ratio with the respective 95% confidence intervals. The variables with P≤0.20 in the individual analyses were tested in multiple logistic regression models, remaining the variables with P≤0.05. The results showed a statistically significant association for the esthetic impact (Aesthetic Component of the Index of Orthodontic Treatment Need and the Oral Aesthetic Subjective Impact Scale) when assessing the normative orthodontic treatment need by the DAI (P<0.05). However, there was no significant association between subjective esthetic impact and normative needs when using the IOTN-DHC (P>0.05). DAI was more associated with the adolescents' esthetic concern than IOTN-DHC and should be the Index of Orthodontic Treatment Need to be selected to complement the patient's self-perception.

Cross-Cultural Adaptation and Validation of "Malocclusion Impact Questionnaire" into Moroccan Arabic.

Introduction The malocclusion index questionnaire (MIQ) is widely used in research and clinical practice. To our knowledge, there are no studies of its use in Moroccan patients. Aim The objective of this study was to translate and culturally adapt the malocclusion impact questionnaire (MIQ) into Moroccan Arabic and to assess its reliability and validity among a sample of young Moroccan teenagers. The PIDAQ was cross-culturally adapted into Malay version by forward- and backward-translation processes, followed by psychometric validation. Materials and Methods The MIQ was cross-culturally adapted into Moroccan Arabic by forward- and backward-translation processes, followed by psychometric validations. The MIQ was completed by a representative sample of 94 Moroccan adolescents aged 12–17 years selected randomly from five public schools of Casablanca. Internal consistency reliability was determined from Cronbach's alpha, and the intraclass coefficient of the item scores was obtained in 1 month in a subset of 30 subjects. Data were analyzed using the Statistical SPSS software, version 16.0, SPSS Inc, Chicago, IL, USA. Results The MIQ was completed twice by each participant at one-month interval to assess test reliability; the intraclass coefficient was r = 0.958, showing an excellent reproducibility. The internal consistency demonstrated the reliability of the questionnaire with Cronbach's alpha coefficient of 0.917. The validity of the questionnaire was assessed by evaluation of the relationship between the total scores of the MIQ and normative need for orthodontic treatment according to ICON. The questionnaire showed an insignificant correlation (0.129, p < 0.05). Conclusion The Moroccan Arabic version of the MIQ was found to be reliable, whereas it has unacceptable validity according to ICON, and hence, it is unlikely to be a useful measure in orthodontic clinical trials for Moroccan adolescents.

Item-level analysis of the relationship between orthodontic treatment need and oral health-related quality of life in Korean schoolchildren.

This study aimed to evaluate the associations between normative orthodontic treatment need and oral health-related quality of life (OHRQoL) at an item level as well as subscale and total score levels among schoolchildren. A cross-sectional study was conducted on 2,010 randomly selected children aged approximately 8, 10, 12, and 15years residing in the Gyeonggi province, Korea. Children were clinically examined with the Index of Orthodontic Treatment Need (IOTN). To measure OHRQoL, the Child Oral Health Impact Profile (COHIP) was used. In the physical health domain of COHIP, crooked teeth, discoloration, "food sticking," and "difficulty keeping teeth clean" were significantly associated with IOTN levels (P<0.05), whereas pain, sensitivity and bleeding, bad breath, mouth breathing, and dry mouth were not. In addition, present and future dental health were significantly associated with IOTN levels, although self-confidence, attractiveness, and future health were not. As expected, the 5 subscale scores and total score of COHIP were significantly associated with IOTN levels after adjustment for gender, age, socioeconomic level, and caries state. This study suggests the importance of in-depth investigation at the item level of OHRQoL assessment scales to better evaluate the impact of malocclusion that might be alleviated by orthodontic treatment.

Influence of sense of coherence on adolescents\u2019 self-perceived dental aesthetics; a cross-sectional study

BackgroundSense of coherence (SOC) is a psychosocial factor capable of influencing perception of health, improving one’s ability to manage life. It is the central construct of salutogenesis. SOC allows for identification and mobilization of resources to effectively manage or solve problems, promoting health and quality of life. Using Wilson-Cleary’s conceptual model we hypothesized that SOC might contribute to self-perception of dental aesthetics. The aim of this study was to investigate whether SOC levels were related to self-perception of dental aesthetics against assessed normative orthodontic treatment need among adolescents.MethodsA cross-sectional study was conducted with 615 male and female adolescents aged 12 to 15 years. Data collection comprised socio-demographic and socio-economic characteristics, SOC (SOC 13), self-perceived dental aesthetics (Oral Aesthetic Subjective Impact Scale), and assessment of orthodontic treatment need (Dental Aesthetic Index). Statistical analysis involved Pearson’s chi-square test, Kruskal-Wallis test, Mann-Whitney test and multiple linear regression. Spearman’s correlation coefficient was calculated for the determination of the strength of correlations among the numerical variables. The level of significance was set at 5% (p < 0.05).Results50.1% of the participants were classified as having a high SOC (≥ median). Overall, SOC was associated with self-perceived dental aesthetics (p = 0.048). In the adolescents with no orthodontic treatment need, those with a low SOC perceived their dental aesthetics more negatively than those with high levels of SOC. The multiple regression analysis demonstrated an inverse relationship between SOC and: 1) age (p = 0.007), SOC being higher in the younger age group; 2) self-perceived dental aesthetics (p = 0.001), a higher SOC being associated with those who had a positive dental self-perception.ConclusionsSOC was associated with self-perceived dental aesthetics and adolescents with a high SOC were more likely to perceive their dental aesthetics more positively. SOC did not seem to influence self-perception of dental aesthetics in adolescents who were clinically assessed as having an orthodontic treatment need, however, in those where there was no orthodontic treatment need, a low SOC was associated with a negative self-perception of dental appearance.

Normative need for orthodontic treatment and perception of the need for such treatment among Brazilian adolescents

ABSTRACTObjective: The aim of the present study was to evaluate the normative need for orthodontic treatment and the perception of such need among students aged 11-14 years. Methods: A cross-sectional study was conducted with a sample of 346 students, randomly selected from public and private schools. The Dental Aesthetic Index (DAI) was used to evaluate the normative need for orthodontic treatment (NNOT). The perceived need for treatment among students was assessed by a previously validated questionnaire. Data was analyzed by Pearson’s Chi-squared test (α = 5%). Results: The prevalence of malocclusion and NNOT was 65.6%. Of the sample, 73.7% felt they needed treatment, 66.2% wanted orthodontic treatment and 62.7% were satisfied with their dental aesthetics. A statistically significant association was observed between NNOT and the perception of the need for treatment among the students (p < 0.001). Conclusion: The present study demonstrated a high prevalence of malocclusion, which was reflected in the high normative need for orthodontic treatment. The opinion of patients regarding their expectations of orthodontic treatment should be valued. The students perceived a need for orthodontic treatment.

OBJECTIVE AND SUBJECTIVE EVALUATION OF ADOLESCENT'S ORTHODONTIC TREATMENT NEEDS AND THEIR IMPACT ON SELF-ESTEEM.

ABSTRACTObjective: To investigate the presence of association between objective and subjective evaluation of orthodontic treatment needs in adolescents and their impact on their self-esteem.Methods: Cross-sectional study with adolescents aged 10-17 years old in Sri Ganganagar city, Rajasthan, India. The objective index of orthodontic treatment need (IOTN) dental health component (DHC) and the subjective aesthetic component (AC) were used to determine the normative and the self-perception need for orthodontic treatment, respectively. The selected students were further examined for dental trauma, tooth loss, and dental caries. Rosenberg Self-Esteem Scale was applied for self-esteem level determination. Linear regression analysis was executed to test the individual association of different independent clinical variables with self-esteem scores. Results: Among 1,140 studied adolescents, the prevalence of dental normative orthodontic treatment need was in 56.9% of individuals, whereas 53.3% of individuals considered themselves as needy for the treatment. Multivariate analyses revealed that out of all dental disorders, DHC followed by AC of IOTN had maximum impact on the self-esteem of the adolescence. Conclusions: Dissatisfaction with dental appearance is a strong predictor for low self-esteem in adolescence.

Prevalence of Malocclusions and Normative Orthodontic Treatment Need Using IOTN Index for Patients in Yalgado Ou&amp;#233;draogo Teaching Hospital

Introduction: The assessment of health care needs must be reproducible, independent of the operator, hence the use of indexes like the Index of Orthodontic Treatment Need (IOTN). The aim of this study was to assess both, the prevalence of malocclusions among patients received in the Dental Surgery Unitat Yalgado Ouédraogo Teaching Hospital and their care needs according to IOTN index. Materials and Methods: It is a prospective, cross-cutting diagnostic study of malocclusions at Yalgado Ouédraogo Teaching Hospital (CHUYO), conducted from January 1 to December 31, 2016. The examiner with an examination tray records on the 12- to 16-year-old patients’ medical recorded, the variables based on the polychromatic pictures series, the IOTN rule, and the dental health component table. Results: On the whole, 81 patients were included, with 60.5% of girls and 39.5% of boys. 16- and 12-year-old patients were dominant. The average age was 14.05 years old. Various types of malocclusions were encountered. The need for orthodontic care was 56.8%. For 14 patients, 17.28%, their aesthetic component score is higher than the assessment made by the orthodontist. Conclusion: Aesthetics was an important factor in the need for orthodontic care. The aesthetic deficit entails a psychological impact that should be taken into account in the assessment of care needs.

Perception of children and mothers regarding dental aesthetics and orthodontic treatment need: a cross-sectional study.

BackgroundThe normative orthodontic treatment need, established by dental professionals during the dental appointment, becomes ineffective when it does not evaluate all the factors that influence the decision-making process, including individuals’ perception and satisfaction with their dental appearance. Therefore, the purpose of this study was to investigate the perception of children and their mothers as regards orthodontic treatment need and satisfaction with dental aesthetics and test if these variables are associated with the objective orthodontic treatment needs, assessed by the Dental Aesthetic Index (DAI).MethodsA cross-sectional study was conducted on 308 children aged 12 years, and their mothers were randomly selected by cluster sampling (primary schools). The variables “orthodontic treatment need,” “satisfaction with chewing,” and “dental appearance” were assessed by means of a questionnaire. The questions were answered individually at school or home, in cases of children or mothers, respectively. DAI was assessed to make an objective clinical assessment. The variables were dichotomized and statistically analyzed by the chi-square and Fisher’s exact tests, contingency coefficient C, and logistic regression.ResultsThe results of the clinical evaluation (DAI) were statistically associated with the perception of orthodontic treatment need and satisfaction with dental appearance in children (p ≤ 0.01). However, no association was observed with regard to satisfaction with chewing and DAI (p = 0.10). The children’s perception of orthodontic treatment need and satisfaction with the appearance of their teeth was statistically associated (p ≤ 0.01) with their mothers’ perception. Maxillary overjet, maxillary and mandibular misalignment, and dental crowding were associated with the orthodontic treatment need by children and their mothers, with p value −0.05 and 5 % level of significance. Maxillary overjet was a significant predictor for the perception of orthodontic treatment need in children (OR 1.86, 95 % CI 0.98–3.55) and mothers (OR 3.02, 95 % CI 1.54–5.92).ConclusionsChildren and parents realize the need for orthodontic treatment according to the different types of malocclusion, as noted in the association between orthodontic treatment need and dental appearance perceived by children and their mothers, which was also observed—with low correlation—with regard to DAI.

Association between normative and self-perceived orthodontic treatment need in a Lebanese population.

The aims of this study were to investigate the association between normative and perceived orthodontic treatment need in a Lebanese population and the effect of sociodemographic status on orthodontic treatment need. A prospective cross-sectional clinical study was designed using a sample of 150subjects (81males and 69females) aged 11-18years seeking dental treatment at Beirut Arab University. Normative orthodontic treatment need was scored using the two components of the Index of Orthodontic Treatment Need (IOTN), the Dental Health Component (DHC) and the Aesthetic Component (AC). Perceived need for orthodontic treatment was evaluated by scoring the AC of the IOTN. A total of 31.3% of the sample were in great need of orthodontic treatment according to the DHC of the IOTN. On the other hand, only 9% of the sample perceived their need to be definite. A significant positive but weak correlation was found between the normative and perceived need for orthodontic treatment. There was also a significant association between age and normative treatment need.

Self-perceived need for dental treatment and related factors. A cross-sectional population-based study

This study compared adolescents' self-perceived need for orthodontic treatment with the normative need for such treatment and investigated associations between socioeconomic and demographic variables and self-perceptions of dental malocclusion. This cross-sectional study involved 1015 schoolchildren aged 12-15 years in São Luís, Maranhão, Brazil. The following data were collected using a questionnaire and an orthodontic examination card: demographic and identifying data, socioeconomic data, educational levels of family, household income, economic classification criteria, and self-reported skin color behavioral data, and oral health data. Normative occlusal condition was examined using the Angle classification and Dental Aesthetic Index (DAI). Data were analyzed using the chi-squared test (to analyze differences in the frequency distribuition of qualitative variables) and Poisson regression (to stimate associations between the perceived need of orthodontic treatment and study covariates), with a 5% significance level. Schoolchildren's self-perceived need for orthodontic treatment was associated with sex (p = 0.022) and the normative need for treatment (p = 0.004). Among socioeconomic, demographic, and oral health variables, only sex [prevalence ratio (PR) = 1.15; 95% confidence interval (95%CI) = 1.04-1.28; p = 0.009] and the normative need for orthodontic treatment (PR = 1.19; 95%CI = 1.08-1.32; p < 0.001) were associated with the perception of malocclusion, with female adolescents reporting a greater need for orthodontic treatment. Female adolescents seems to be more sensitive to oral health problems. The results suggest that the DAI score might reflect a self-perceived need for orthodontic treatment and the Angle classification might overestimate the orthodontic treatment need.

Adaptation and validation of the Moroccan Arabic version of the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ).

ObjectiveThe aims of this study were to translate and culturally adapt the PIDAQ native English version into Moroccan Arabic, and to assess the psychometric characteristics of the version thereby obtained.Materials and methodsThe PIDAQ original English version was sequentially subjected to translation into Moroccan Arabic, back-translation into English, committee review, and pre-testing in 30 subjects seeking orthodontic treatment.ResultsThe final Moroccan Arabic version further underwent an analysis of psychometric properties on a random sample of 99 adult subjects (84 females and 15 males, aged 20.97 ± 1.10 years). The intraclass coefficient correlation of the scores of the responses obtained after administration of the questionnaire twice at a 1-month interval to a random sample of 30 subjects ranged from 0.63 for “Self-confidence” to 0.85 for “Social Impact”. Cronbach α coefficients ranging from 0.78 for “Aesthetic Concerns” to 0.87 for “Self-confidence” were obtained; the different subscales of the Moroccan Arabic version of the PIDAQ showed good correlation with the perception of aesthetics and orthodontic treatment need.ConclusionThe results of the present study indicate that the Moroccan Arabic version of the PIDAQ obtained following thorough adaptation of the native form is both reliable and valid. It is able to capture self-perception of orthodontic aesthetic and treatment need and is consistent with normative need for orthodontic treatment.

Normative and self-perceived orthodontic treatment need in Nigerian school children

Objective. The aim of this study was to assess the normative and self-perceived need for orthodontic treatment in Nigerian children, and to evaluate distribution of orthodontic treatment need according to gender and age. Materials and methods. The sample consisted of 441 randomly selected school children, aged 11–18 years in Benin City, Nigeria. The subjects were further sub-grouped according to gender (229 males and 212 females) and age (246 11–13 years old and 195 14–18 years old). The Dental health Component (DHC) and Aesthetic Component (AC) of Index of Orthodontic Treatment Need (IOTN) were used to assess orthodontic treatment need normatively. Self-perceived need was evaluated by asking the subjects to rate their dental aesthetics on the Aesthetic Component scale of IOTN. Chi-square tests were used to evaluate gender and age differences in distribution of treatment need. Results. A definite need for orthodontic treatment was found among 21.5% (grades 4–5 of DHC) and 6.3% (grades 8–10 of AC) of the subjects; 3.9% of the subjects perceived a definite need for orthodontic treatment (grades 8–10 of AC). There were no statistically significant gender and age differences in distribution of orthodontic treatment need among the subjects (p > 0.05). Conclusion. The study revealed a need for orthodontic treatment in slightly more than one fifth (21.5%) of this sample of Nigerian children. The sample population has a lower need on aesthetic grounds and their normative and self-perceived orthodontic treatment needs were not influenced by gender and age.

Dissatisfaction with dentofacial appearance and the normative need for orthodontic treatment: determinant factors.

ObjectiveThis study aims at assessing the normative need for orthodontic treatment and the factors that determine the subjective impact of malocclusion on 12-year-old Brazilian school children.MethodsA total of 451 subjects (215 males and 236 females) were randomly selected from private and public schools of Juiz de Fora, Brazil. The collected data included sociodemographic information and occlusal conditions. The esthetic subjective impact of malocclusion was assessed by means of the Orthodontic Aesthetic Subjective Impact Score - OASIS, whereas the malocclusion and the need for orthodontic treatment were assessed by means of the Dental Aesthetic Index (DAI) and the Index of Orthodontic Treatment Need-Aesthetic Component (IOTN-AC).ResultsPrevalence of normative need for orthodontic treatment was 65.6% (n = 155), and prevalence of orthodontic esthetic subjective impact was 14.9%. The following variables showed significant association with esthetic subjective impact of malocclusion: female (p = 0.042; OR = 0.5; CI = 0.2-0.9), public school student (p = 0.002; OR = 6.8; CI = 1.9-23.8), maxillary overjet ≥ 4 mm (p = 0.037; OR = 1.7; CI = 1-3) and gingival smile ≥ 4 mm (p = 0.008; OR = 3.4; CI = 1.3-8.8).ConclusionThe normative need for orthodontic treatment overestimated the perceived need. Occlusal and sociocultural factors influenced the dissatisfaction of schoolchildren with their dentofacial appearance.

Factors influencing the perceived orthodontic treatment need and its relationship with awareness of malocclusion among college adolescents

Introduction: The orthodontic need assessment is of interest for dental public health programs. The major factors determining a patient's perceived need for orthodontic treatment may be aesthetic, functional, financial, or social. Adolescents seeking orthodontic treatment have been found to have poorer aesthetics than their peers, but whether poor aesthetics alone generates greater treatment demand has not been determined in the Indian context. Objective: The aim was to study the factors determining perceived orthodontic treatment need among college adolescents. Materials and Methods: A total of 448 adolescents between 17 and 19 years of age were selected randomly from the colleges. Data were collected on pretested and standardized questionnaire. Perceived need for orthodontic treatment was assessed by asking question to the participants. Dental Esthetic Index (DAI) was used to assess the severity of malocclusion. Results: The prevalence of malocclusion was 21.6% as per DAI. The perceived need for orthodontic treatment was 11.2%, though the level of dissatisfaction with dental appearance was 19.2%. No agreement was seen between the treatment need assessed objectively by DAI and that perceived by the patient. The determinants for perceived and normative orthodontic treatment need were socioeconomic status (SES), awareness of malocclusion, dissatisfaction with dental appearance and avoided smile due to dental appearance. The positive correlation between perceived and normative need was statistically significant. Conclusion: The uptake of orthodontic care may be influenced by SES, awareness of malocclusion; dissatisfaction with dental appearance, perceived need and DAI score.
