To investigate the association between orthodontic treatment need (OTN) and caries experience (CE).
Using a stratified sampling method, 748 subjects (355 females, 393 males; mean ± standard deviation age 15.11 ± 2.23 years) were examined. The Dental Aesthetic Index (DAI), DMFT, simple (DMFT > 0) and severe CE (DMFT > 8) were recorded. Socio-economic status (SES) was assessed by recording parental education, mother's employment status, and household size.
Higher (but not statistically significant) CE was observed in subjects with OTN (DAI > 30). The association between DAI and DMFT scores was not significant (rho = 0.05). Mean DMFT score did not vary significantly between the SES and OTN subgroups. In children with a household size >6 persons (n = 85), OTN was associated with higher CE and a higher prevalence of severe CE compared with those without OTN. In this group, when DAI treatment need grade increased, severe CE prevalence also increased from 10.8% to 50%. Similarly, in those with OTN and household size >6 persons, the odds of observing subjects with severe CE was 4.6 times higher (95% confidence interval 1.45-14.55) compared to those without OTN.
Associations were observed between OTN and CE and also between the prevalence of severe CE and the severity of malocclusion in children with a household size >6 persons. The current findings suggest that the relationship between caries experience and malocclusion should be assessed in a wider context of SES and background factors.

    • "At the same time, orthodontic treatment reduces the rate of maxillary anterior teeth caries, There is no statistical differences with mandibular anterior teeth, which considered to be the easiest to decay. And disagrees with previous investigations showing that orthodontic increased the incidence of dental caries [6] [7]. "

    ABSTRACT: Objectives: The aim of this study was to assess the relationship between orthodontic and the development of dental caries in the same patients who received single jaw orthodontic treatment. Material and methods: A consecutive sample consisted of 60 subjects who required single upper jaw orthodontic were recruited consecutively from the Department of Orthodontic at the Stomatology Hospital of Wenzhou Medical University. The dental examinations were routinely carried out by one dentists at the following stages: pre-treatment (T1); post-treatment (T2); more than 7 years after T1 (T3). The DMFS count which reflect the caries experience was recorded. Results: There was no significant difference between the treated groups and untreated groups for the DMFS before received fixed orthodontic treatment. The same result was found after orthodontic treatment. However, the average number of DMFS in the treatment jaw after fixed orthodontic treatment was lower than in the without treatment jaw after long-term follow-up period. Conclusions: Fixed orthodontic appliances significant decrease the patients caries risk after orthodontic treatment. Weiting Chen, Yu Zhou

    • "The prevalence of malocclusion was found to be higher among females (36.3%) than males (32.5%). Similar findings were reported by Gauba et al (1998) and Suma et al (2011), while Ahammed et al (2013), Aikins et al (2011), Borzabadi-Farahani et al (2011), Shivakumar et al (2009) and Tak et al (2013) reported higher malocclusion scores among male subjects. However, Borzabadi-Farahani et al (2011), Babu and Gopu (2011) and Cavalcanti et al (2013) found no correlation of treatment need with gender. "

    ABSTRACT: Malocclusion has great impact on society and the individual in terms of social and functional limitations, psychological trauma and discomfort. The Dental Aesthetic Index (DAI) is a WHO recommended method of screening for dentofacial anomalies and orthodontic treatment need. This survey was conducted to determine the prevalence of malocclusion and orthodontic treatment need among high school students in Mangalore city, Karnataka State, India. List of schools in Mangalore city was obtained from the Block Educational Officer. After obtaining consent from the relevant authorities, four schools were selected by random sampling (lottery method). In these schools, all students who fulfilled the inclusion criteria were examined with the help of a recorder. A proforma was used to record demographic data (name of the student and school, age, gender), and the criteria of the DAI for each subject. Data were analyzed using the Chi squared test and a p-value of < 0.05 was considered statistically significant. Study subjects numbered 422 and ranged in age from 11-18 years. According to the DAI criteria, 66.1% subjects had no abnormality or minor malocclusion (requiring little or no orthodontic treatment), 22.3% had definite malocclusion (in whom orthodontic treatment was an elective option), 9.9% presented with severe malocclusion (with orthodontic treatment being highly desirable) and 1.7% had very severe or handicapping malocclusion (requiring mandatory orthodontic treatment). Malocclusion and orthodontic treatment need were found to be present in 33.9% of the population surveyed. These data will help in planning and executing appropriate measures to overcome this oral condition.

    • "The link between the malocclusion and dental health has not been firmly established yet,[1213] but deterioration in oral health during orthodontic treatment is a matter of interest. Clinicians should take any known steps toward preventing the potential risks of decalcification and periodontal disease during orthodontic treatment. "

    ABSTRACT: Background: To compare changes in the amount and distribution of dental plaque associated with placement of elastomeric modules over a self-ligating bracket during orthodontic treatment and to relate these changes to the periodontal inflammation. Materials and Methods: A cross-arch randomization trial was carried out at Bristol Dental School, United Kingdom. Clinical measurements of periodontal inflammation and plaque accumulation and microbiological test were done on 24 patients aged 11-14 years [Mean (SD) age = 12.6 (1.01) years] wearing fixed appliances (Damon 2 brackets, Ormco, Orange, CA, USA) at the start and 3 months into fixed orthodontic treatment. Results: In the first 3 months of treatment there was no statistically significant difference in bleeding on probing between incisors with and without elastomeric modules (P = 0.125 and 0.508, respectively). The difference in plaque accumulation was not statistically significant (P = 0.78). The difference in probing depths between the incisors was not statistically significant (P = 0.84). The microbiological analysis showed no difference. Conclusions: Based on this preliminary 3 months study, elastomeric modules were not significantly associated with any increased risk during treatment when compared to self-ligating brackets. The longer term studies are needed to further confirm the findings of the present study.
