Quality of orthodontic care-A multicenter cohort study in a German convenience sample : Part 2: Cross-sectional patient-reported outcomes after orthodontic treatment.

OBJECTIVES: In light of the growing interest in orthodontic care and its effectiveness in Germany, part 2 of this multicenter cohort study evaluated patient-reported outcomes such as oral health-related quality of life (OHRQoL), oral hygiene habits, oral health beliefs, and potential influencing factors. METHODS: Of 586 patients screened from seven German study centers, data from 343 patients were analyzed for this part of the study. At the end of their orthodontic treatment, study participants filled out a questionnaire of either the German long version of the Oral Health Impact Profile (OHIP-G 49) or the German short version of the Child Oral Health Impact Profile (COHIP-19), depending on their age, as well as questions about their oral hygiene behavior and beliefs. Patient-, treatment- and occlusion-related factors were analyzed to account for potential influencing factors with regard to patients' OHRQoL after orthodontic treatment. RESULTS: In all, 222 study participants filled out the OHIP-based and 121 the COHIP-based questionnaire. The mean OHIP-G 49 score was 12.68 and the mean OHIP-G 14 score was 3.09; the mean COHIP-19 score was 6.52 (inverted score 69.48). For OHIP-G 49 scores, a nonsignificant trend towards a higher score for male patients (14.45 vs 11.54; p = 0.061) was detected, while this trend was inverse for the COHIP-19 scores, i.e., female patients reported more impairment (total score 6.99 vs. 5.84; p = 0.099). Analyses suggested a trend towards better OHRQoL for patients who classified for the Peer Assessment Rating (PAR) Index improvement rate group 'greatly improved' as well as for nonsmokers. Oral hygiene habits and beliefs after orthodontic treatment were estimated to be good. CONCLUSION: In this German cohort, OHRQoL proved to be good and was rather unimpaired after orthodontic treatment. Furthermore, self-reported oral hygiene behavior and oral health beliefs represented good health awareness.

The tongue microbiome of young patients with chronic kidney disease and their healthy mothers.

OBJECTIVES: Oral microbiome plays a crucial role in the incidence and development of oral diseases. An altered intestinal microbiome has been reported in adults with chronic kidney disease (CKD). This study aimed to characterize the tongue microbiome of young patients with CKD compared to their healthy mothers to identify the influence of CKD-associated factors on resilient tongue ecosystem. MATERIAL AND METHODS: Thirty patients with CKD (mean age, 14.2 years; 16 males and 14 females) and generalized gingivitis were included in the study. Swabs of the posterior tongue were collected from the patients and 21 mothers (mean age 40.8 years). Next-generation sequencing of 16S rDNA genes was employed to quantitatively characterize microbial communities. RESULTS: The bacterial communities were similar in terms of richness and diversity between patients and mothers (p > 0.05). In patients with CKD, 5 core phyla, 20 core genera, and 12 core species were identified. CONCLUSIONS: The tongue microbiome of the study participants showed no relevant CKD-associated differences compared to their mothers and appears to be a highly preserved niche in the oral cavity. Differences observed in the abundance of individual species in this study could be attributed to the age rather than CKD, even after a mean disease duration of 11 years. CLINICAL RELEVANCE: CKD and its associated metabolic changes appear to have no detectable impact on the resilient tongue microbiome observed in young patients.

Looking good but tweeting bad? The social perception of orthodontic-related posts on Twitter and Instagram.

BACKGROUND: Social media plays a major role in the daily life of adolescents and has become highly interesting for healthcare research as well. The aim of this study was to explore the social perception of orthodontic-related posts on Twitter and Instagram by young adults. METHODS: 401 orthodontic-related posts were collected during a 30-day period and categorized with regard to specific characteristics - their content and the social networking site (SNS) being used as well as the presence or absence of a selfie. In order to investigate the social perception of these posts, 42 young adults rated the emotional states of the SNS users using the Self-Assessment Manikin (SAM)-Tool. A total of 4211 poster-rater observations pertaining to the three SAMs dimensions pleasure, arousal and dominance were analyzed by using linear and multinomial logistic regression analyses. RESULTS: The investigated characteristics of the collected posts had significant effects on the perceived emotional state of the SNS users. Besides significant SNS-associated differences, there were also effects that were independent of the SNS being used: Receiving orthodontic appliances was more often associated with rather negative emotions (p < 0.001), while users who posted about the removal of such braces were more often perceived as joyful (p < 0.001). Interestingly, users whose posts contained selfies with visible braces were perceived as significantly more positive and stronger in comparison to users who did not post a picture of themselves (p < 0.05). CONCLUSION: This research gives insights into the social perception of orthodontic-related posts on SNS. While users' emotional states were perceived highly differential on both SNS, orthodontic-related content also revealed significant effects on social perception. Because selfies with visible braces were associated with positive feelings by young adults, a modern and SNS-related way of coping with a temporary supposed impairment like fixed orthodontic appliances might have been revealed through this research.

Social media and orthodontics: A mixed-methods analysis of orthodontic-related posts on Twitter and Instagram.

INTRODUCTION: In modern health care, social media has become an important tool for both patients and professionals. On platforms like Twitter and Instagram, patients can express their experiences, attitudes, and emotions regarding their orthodontic treatment or the available treatment options. This study aimed to investigate orthodontic-related social media use by analyzing the contents of posts made by patients and/or peers and exploring potential differences of users' attitudes on Twitter and Instagram. METHODS: During a 30-day period, we collected 361 orthodontic-related posts-153 from Twitter and 208 from Instagram-using the same search strategy on both platforms. A mixed-methods approach was applied. First, all posts were structured according to a qualitative content analysis. Subsequently, quantitative analysis was performed to detect potential differences between posts on Twitter and Instagram. RESULTS: The following main themes were identified: "Getting braces" and "Getting braces removed," "Limitations due to braces," "Seeking information," and "Comedy." In addition to this classification, all posts were categorized as positive, negative, or neutral. Pictures and emoticons were frequently used to express experiences, attitudes, and emotions regarding orthodontic appliances. There were significant differences between posts on Twitter and those on Instagram; that is, the latter contained more posts that were categorized as positive. CONCLUSIONS: To date, only a few studies addressed the role of social media for orthodontic patients. This study provided insights into the experiences, attitudes, and emotions of patients and their peers regarding orthodontics and helped to reveal the potential impact of social media use on the field of orthodontics. Attention must be paid to the functional differences between Twitter and Instagram because these might lead patients to express themselves in specific ways.
