Background and objectives: Although the main objective of any orthodontic treatment is to correct malocclusion, a range of psychosocial and/or esthetic factors drive patients to undergo orthodontic treatment. The aim of the present study was to analyze variations in oral health-related quality of life (OHRQL) levels in patients undergoing orthodontic treatment by means of four types of appliances: fixed buccal metal brackets, fixed buccal esthetic/ceramic brackets, fixed lingual brackets, and clear aligners. Material and Methods: The study sample comprised 120 patients aged 18 to 68 years who attended the Orthodontic department at the Dental Clinic of the University of Valencia. The Index of Orthodontic Treatment Need (IOTN) was used to measure orthodontic treatment need. Each patient completed three different intervals of the 14-item Oral Health Impact Profile (OHIP-14): before treatment (T0); six months after placing the orthodontic appliances (T1) and at the end of orthodontic treatment (T2). Results: All groups suffered a reduction in quality of life from T0 to T1 except the metal bracket group which presented the same level for the functional limitation domain (p = 1.000), the lingual bracket group for the psychological discomfort domain (p = 1.000) and clear aligner group for the physical disability domain (p = 0.118) and psychological disability domain (p = 1.000). Nevertheless, quality of life for most domains was similar in all groups at the end of treatment (T2). Conclusions: Patients underwent a significant reduction in quality of life during treatment in comparison with their pre-treatment condition but showed significant improvements at the end of treatment.

UNASSIGNED: To assess the effect of orthodontic treatment needs on oral health-related quality of life among the young people of Delhi NCR.
UNASSIGNED: The study was conducted on 12-15 years of individuals attending dental clinic/hospital in Delhi NCR region. Data were collected using Index of Orthodontic Treatment Need -Dental Component and oral health impact profile 14 questionnaire. The Chi-square test was used to analyze the qualitative data. SPSS software version 20 was used for statistical analysis.
UNASSIGNED: Orthodontic treatment needs had an almost similar impact on the daily activities of both males and females. The sense of taste was not significantly affected by the need for orthodontic treatment in either males or females. The proportions of orthodontic patients found to have the painful arch, embarrassment, tension, and self-conscious both in males and females.
UNASSIGNED: There is a significant correlation of orthodontic treatment needs among oral health-related quality of life.

OBJECTIVE: To assess oral health-related quality of life (OHRQoL) in young adult patients with malocclusion and to measure the association between orthodontic treatment need and OHRQoL.
METHODS: The study sample comprised 190 young adults aged 18 to 25 years who were attending orthodontic clinics at the Faculty of Dentistry. The Index of Orthodontic Treatment Need-Dental Health Component was used to measure orthodontic treatment need. Each participant was assessed for OHRQoL before and after treatment by using the Oral Health Impact Profile, Chinese version (OHIP-14).
RESULTS: Patients who had little or no, borderline, and actual need for orthodontic treatment represented 21.6%, 50.5%, and 27.9% of the total sample, respectively. OHRQoL (total OHIP-14 score and score for each domain) improved after treatment (P < .05). Significant differences in summary OHIP-14 scores were apparent with respect to orthodontic treatment need. Participants with high treatment need reported a significantly greater negative impact on the overall OHRQoL score. The greatest impact was seen in the psychological discomfort domain and the psychological disability domain.
CONCLUSIONS: Malocclusion has a significant negative impact on OHRQoL. This is greatest for the psychological discomfort and psychological disability domains. The orthodontic treatment of malocclusion improves OHRQoL of patients.

BACKGROUND: The documentation of magnitude of malocclusion in terms of prevalence and severity has not been done till date in Himachal Pradesh, India.
OBJECTIVE: To assess the prevalence of malocclusion and orthodontic treatment needs (OTNs) among 9-and 12-year-old school children by using the Dental Aesthetic Index (DAI) in the state.
METHODS: A cross-sectional study was conducted among 1188 children from randomly selected schools. The survey was done according to the Oral Health Assessment Form (modified). DAI was used to assess the severity of malocclusion, along with collection of demographic data.
RESULTS: The overall prevalence of malocclusion was 12.5% and required orthodontic treatment, whereas 87.5% did not require treatment. A severe malocclusion for which treatment was highly desirable was recorded in 3.1%; 8% had a definite malocclusion for which treatment was elective. Only about 1.3% had a handicapping malocclusion that needed mandatory treatment. Almost equal proportions of males and females were affected with malocclusion with the means 20 ± 4.6 and 19.9 ± 4.9, respectively (P < 0.641). The prevalence and severity of malocclusion was more in 12-year age group than in 9-year age group (P = 0.002**). There was an increase in the proportion of malocclusion among older children: In 12-year age group, 15.7% with mean 20.5 ± 5.1 and in 9-year-old children, 8.9% with the mean 19.3 ± 4.1 were in the need of orthodontic treatment.
CONCLUSIONS: Severity and treatment needs, both are important factors in public health planning.
