“…Several studies suggest that teeth-alignment disorder poses a risk of periodontal diseases, although this has not been established [ 15 , 16 , 17 ]. The present results clearly demonstrated a close association between the awareness of teeth-alignment disorder and bleeding gums, which implies that orthodontic treatment could improve periodontal health status and/or prevent the onset of periodontal diseases [ 18 ]. Certainly, adequate daily brushing is important to prevent periodontal diseases [ 19 ].…”

Background: Oral diseases are associated with various systemic disorders. Our previous research revealed new insights into the close relationship between occlusal disorder (functional disorder) and systemic disorders (allergic rhinitis, asthma, and arrhythmia) in late adolescence. Here, we investigated whether there was an association between the awareness of teeth-alignment disorder (morphological disorder) and common systemic disorders. Subjects and Methods: We retrospectively reviewed the data of the mandatory medical questionnaire that is required for the freshman medical checkup in Japan. We collected the data of all students who completed the questionnaire between April 2017 and April 2019. The data were analyzed using the χ2 test, and a multivariate analysis was performed with a binomial logistic regression model. Results: The subjects were 8903 students aged 17–19 who had no awareness of occlusal disorder. The rate of awareness of teeth-alignment disorder was 20.43% (1819 of 8903 eligible subjects), and the aware students had significantly greater rates of gum bleeding (p < 0.001), pollinosis (n = 0.007), and atopic dermatitis (n = 0.042). The multivariate analysis revealed significant rates of gum bleeding (odds ratio (OR) 1.540, 95% confidence interval (CI): 1.386–1.711, p < 0.001), pollinosis (OR 1.197, 95% CI: 1.040–1.378, p = 0.012), and female gender (OR 1.141, 95% CI: 1.002–1.299, p = 0.046) among the students with awareness of teeth-alignment disorder. Conclusion: We identified close associations between the awareness of teeth-alignment disorder and both gum bleeding and pollinosis in a late-adolescent population. The systemic disorders that are targeted by teeth-alignment disorder were found to be different from those targeted by occlusal disorder.

“…This cross-sectional study intended to ll this gap in the current literature by using population-based data to comprehensively assess the effect of orthodontic treatment on dental caries experience, prevalence, and severity later in life by using a sample representative of U.S. adults. Ideally, such assessments would use a randomized clinical trial or a prospective cohort study design, but that would introduce ethical issues as to why some participants received treatment and others did not (17).…”

“…However, current research is focused on the oral health bene ts of orthodontic treatment, beyond its esthetic bene ts (17). Data outlining the ability of orthodontic treatment to reduce the risk of dental caries development later in life remains contradictory and inconclusive (18)(19)(20)(21) with low methodological quality (17). The low quality of these studies can be mainly attributed to the absence of a detailed sampling process, the exclusion of response rate reporting, and inappropriate sample size calculation (17).…”

“…Identi cation of high-risk individuals would allow for the application of the appropriate strategies, wherein those with severe dental caries can bene t from individual-speci c prevention approaches such as orthodontic treatment (22). A recent systematic review (17) indicated an increasing need for additional studies to test the effects of orthodontic treatment on the development of dental caries later in life. Thus, this population-based crosssectional study aimed to assess the effects of orthodontic treatment on dental caries experience, prevalence, and severity in adults in the U.S.…”

Background: As the current evidence remains contradictory and inconclusive, there is an urgent need to determine the ability of orthodontic treatment to reduce the risk of dental caries development later in life. Thus, the objective of this study is to assess the effects of orthodontic treatment on the experience, prevalence, and severity of dental caries later in life in a representative sample of U.S. adults.Methods: Using a population-based study design, data from 9,486 participants in the third National Health and Nutrition Survey (NHANES), including self-reported information on previous history of orthodontic treatment and its timing, were obtained. Caries experience and prevalence was assessed using the decayed (DT) and filled (FT) teeth indices (i.e., DT>0, FT>0, and their aggregate DFT>0). Severe dental caries experience and prevalence was defined as DT>2, FT>11, and DFT>12. Unadjusted and adjusted logistic regression models that accounted for the complex sampling design were used to assess the association between orthodontic treatment and dental caries experience, prevalence, and severity. Statistical significance was set at a p-value of less than 0.05.Results: Previous history of orthodontic treatment was reported in 19.62% of the adults. Around 94% of participants had at least one decayed or filled tooth (DFT>0), and 21.09% met the aggregate DFT criterion for severe caries (DFT>12). After controlling for confounding variables, a reported history of orthodontic treatment was found to significantly decrease the odds of DT>0, DT>2, FT>11, and DFT>12 (odds ratios [OR] = 0.41, 0.36, 0.74, and 0.60 respectively).Conclusion: A history of orthodontic treatment was a protective factor for untreated dental caries, in assessments of the severity and prevalence of dental caries experience.

“…Malocclusion traits can be successfully alleviated by orthodontic treatment [15], which largely aims to enhance the social and psychological well-being of patients by improving their appearance [16]. However, current research is focused on the oral health benefits of orthodontic treatment, beyond its esthetic benefits [17]. Data outlining the ability of orthodontic treatment to reduce the risk of dental caries development later in life remains contradictory and inconclusive [18][19][20][21] with low methodological quality [17].…”
