The need for orthodontic treatment was assessed using the DAI categorized into: DAI 1 (absence of malocclusion and orthodontic treatment need; DAI ≤ 25); DAI 2 (malocclusion is defined and elective orthodontic treatment is needed; DAI = 26 to 30); DAI 3 (severe malocclusion and a desirable orthodontic treatment need; DAI = 31 to 35) and DAI 4 (severe malocclusion and a mandatory orthodontic treatment need; DAI ≥ 36). The Bowker symmetry test was used to determine agreement in the categorization of DAI at T1 and T2, with a significance level of 5%. The results showed a significant disagreement in the need for orthodontic treatment between T1 and T2 (p<0.05). In 34.6% of children evaluated in T1, the same need for orthodontic treatment was maintained in T2. According to the DAI, in 60.8% of the children, the need decreased, and in 39.2% their need for orthodontic treatment increased. This preliminary longitudinal study using DAI, showed a decrease in malocclusion and need for orthodontic treatment as the dentition transitioned from mixed to permanent occurred. This finding has valuable implications for epidemiological data in orthodontics.</p>","PeriodicalId":9240,"journal":{"name":"Brazilian oral research","volume":"39 ","pages":"e007"},"PeriodicalIF":1.5,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11745461/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143022277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 268 participants who signed the informed consent were included in the study. The findings revealed that the most common way to find healthcare professionals is through recommendations from friends/relatives and other professionals, followed by the use of social networks. The majority of participants used social networks to search for healthcare professionals, with Instagram being the most widely used platform. Sponsored advertisements can be an effective way to reach potential new patients. The most valued characteristics in healthcare content creators were reliability, expertise, and the ability to convey messages, with health-related explanations in an easily understandable manner being the preferred type of content.
