What are people tweeting about orthodontic retention? A cross-sectional content analysis

Is Social Media a Boon or Bane for Orthodontics in the Current Digital Age: A Cross-Sectional Electronic Survey

BACKGROUND

 Social media is an online platform where people share their experiences, perspectives, and opinions individually or in groups. There has been a rapid increase in internet users after the introduction of social media sites such as Facebook, YouTube, Instagram, and Twitter. Other than primary means of communication, social media aids in distributing healthcare information among professionals and patients. It enhances the knowledge of health care to the patients, but on the contrary, patients can be misguided by false information influenced by unauthorized professionals as it is readily available. With the same objective in mind, the study was undertaken to investigate the perspective of Indian orthodontists on social media use and to assess the potential benefits and disadvantages of social media along with its role in health care education.

MATERIALS AND METHODS

A cross-sectional online questionnaire survey was designed to consist of 42 questions related to the perspectives of Indian orthodontic professionals on the use of social media in orthodontic practice. The questionnaire was sent to 800 registered Indian orthodontists through electronic mail.

RESULTS

A total of only 173 orthodontists responded to the online survey. The electronic survey showed that the phone was the most preferred communication tool in the practice with the patients (87.2%). The most common social media platform for sharing patient information was Instagram (82.5%). The survey showed that none of the orthodontists have received formal training or certification on using social media (85.7%). The reliability of social media platforms is very low (34.9%). Social media would affect the patient's choice of healthcare provider (87.3%). The majority of orthodontists have agreed that there should be regulations for quality control on social media to share patient information (90.5%).

CONCLUSIONS

The study's findings offer valuable insights into the current landscape of social media usage among Indian orthodontists. While social media presents numerous opportunities for communication, education, and practice promotion, it also poses challenges related to training, misinformation, patient privacy, and regulatory oversight. Addressing these challenges requires a concerted effort from orthodontists, regulatory bodies, and digital platforms to develop and implement guidelines that promote responsible social media usage while upholding professional standards and patient welfare. By leveraging social media effectively and ethically, orthodontists can enhance patient engagement, education, and practice visibility in the digital age.

#clearaligners and social media: An in-depth analysis of clear aligners' content on Instagram

BACKGROUND AND OBJECTIVES

Clear aligners-related posts are popularized on social media platforms to educate patients and peers and to market aligners in dental practices. This study aimed to characterize the account credentials and content of the top-performing posts to understand the spread of clear aligners-related information on Instagram.

MATERIALS AND METHODS

This cross-sectional web-based study analysed 13 Instagram clear aligners-related hashtags. Content analysis was performed for the "Top 10 posts" listed under the "Top" section for each hashtag within Instagram, as sorted by Instagram's algorithm. Data were analysed for the poster's background, credentials, role, post format, content, and engagement level ratio. Duplicate posts and those not relevant to clear aligners were excluded. Quantitative and qualitative analyses of the collected data were conducted.

RESULTS

A total of 29 192 596 posts mentioned the selected hashtags, of which 130 posts were screened in this study. Most posts were authored by dentists (n = 84), 79.8% of them were orthodontic specialists. Self-promotional posts comprised 90.2%, while educational posts accounted for only 8.9%. Interestingly, the number of likes and comments received on posts by patients (n = 19, median = 112, IQR = 340) was significantly higher than those posted by dentists (n = 84, median = 93, IQR = 81.75) (P = .004).

CONCLUSION

More than 29 million posts about clear aligners were identified on Instagram. Orthodontists are the leading authors of aligners hashtags. However, the majority of the posts are self-promotional and have nonfactual information. Social media awareness among orthodontic specialists may help provide more evidence-based content about clear aligners and can act as an interactive networking and health communication platform.

Evaluation of orthodontic retention and retainer content on the Reddit social media website

BACKGROUND

Social media can provide insight into patient experiences with health care. The aim of this study was to evaluate the content regarding orthodontic retention and retainers on the social media website, Reddit.

METHODS

A systematic search for relevant content submitted over a 12-month period on the Reddit forum, r/braces, was conducted. Qualitative analysis of the initial posts for themes and subthemes was conducted by two investigators. Responding comments to the initial posts were assessed for supportiveness for each initial poster and alignment with the evidence-base. Quantitative assessment was via descriptive statistics.

RESULTS

A total of 271 initial posts and 984 comments satisfied the inclusion/exclusion criteria. All initial posts were by patients. Just 1.12% (n = 11) of the comments appeared to be provided by oral health professionals. Most initial posts were negative (50.18%; n = 136), and most comments were positive (70.42%; n = 693). Alignment with the evidence-base was high among the comments (67.89%; n = 668). Eight main themes were identified with concerns regarding the negative impact of retention and retainers on quality of life, compliance with retention protocols and relapse commonly expressed. Concern regarding fear of relapse when waiting for the initial or renewal of retainers was a novel finding. More negative sentiments about orthodontists were expressed than positive.

CONCLUSIONS

Reddit is a supportive and reliable environment for patients regarding orthodontic retention and retainers. The content evaluation suggested deficiencies in communication processes between clinicians and patients. Greater engagement of the orthodontic profession in the provision of supportive and evidence-based information on an individual patient basis and through appropriate information channels is required.

Orthodontics in an online community: A computational analysis of r/Braces subreddit

BACKROUND

This study aimed to analyze the semantic network and content analyses of the posts published in a subreddit related to orthodontic treatment on Reddit (Advance Publications, Inc., San Francisco, California).

METHODS

The eight threads in the r/Braces subreddit were divided into two categories: 1) "treatment process" (Braces are off!!!, Braces progress, Before and after!, and Day 1!) and 2) "question/problem" (Question, Discussion!, Need advice! and Rant!). For both categories, a semantic network analysis was performed using the Leximancer software (Leximancer Pty Ltd., Brisbane, Australia). In addition, the quality of the posts published in the "question" thread and the usefulness of the replies provided to these questions (useful, misleading, or neutral) were analyzed.

RESULTS

Seven themes (braces, teeth, months, day, worth, started, and result) that mostly emphasized orthodontic treatment and treatment duration were elicited from the "treatment process" category, and seven themes (teeth, orthodontist, braces, week, bands, brush, and extractions) that mostly emphasized orthodontic treatment, orthodontists, and time were elicited from the "question/problem" category. It was also revealed that users voted on the posts related to the "treatment process" category and moved the posts to the list of top posts on the platform. In the "question" thread, 47.79% of the posts asked for advice and 21.11% of them were related to failures. In addition, 69% of the replies were categorized as "useful."

CONCLUSIONS

Reddit is a successful data mining platform, and the users provide highly useful replies to the questions posted on Reddit regarding orthodontic treatment.

Young people's experiences of orthodontic retainers: A qualitative study

OBJECTIVE

To investigate young people's experiences of retainers, the associated impact of retainers on their lives and their perceptions of what influences their own co-operation.

DESIGN

Qualitative, cross-sectional study.

SETTING

An orthodontic department in a UK dental hospital.

PARTICIPANTS

Purposive sampling was used to recruit young people, aged 11-17 years, wearing a range of different types of retainers.

METHODS

Semi-structured interviews were conducted and transcribed. The resultant data were analysed using codebook thematic analysis.

RESULTS

Ten patients were recruited before thematic saturation was achieved. Four themes were identified: impact and experiences of wearing retainers; facilitators and barriers to retainer adherence; finding out about retainers; and, finally, involvement in decisions about retainers. Although some initial negative impacts were described, participants generally adapted quickly to retainers. Several factors were perceived to influence co-operation with removable retainers, including concerns about relapse and the associated waste of personal effort and wider resources. There were perceived deficiencies in the information provided by clinicians, which led participants to seek advice from other sources, including social media. Some young people wanted to be more involved in decisions about their retainers.

CONCLUSION

While patients perceived retainers to be easier to wear than active appliances, some transient negative impacts occurred, largely related to initial periods of full-time wear. There were a range of factors which patients perceived to influence their adherence with removable retainers.

A cross-sectional study of exposure across social media platforms for the British Orthodontic Society retention awareness campaign: #HoldthatSmile

OBJECTIVE

The use of media campaigns in health promotion has become more common in recent years. #HoldthatSmile is a British Orthodontic Society life-long retention awareness campaign aimed at the general public and dental profession launched in 2017. This study investigated #HoldthatSmile exposure on social media platforms over a 12-month period following campaign launch.

DESIGN

A cross-sectional content analysis.

SETTING

Public-facing, English-language posts tagged #HoldthatSmile on the Facebook, Instagram and Twitter social media platforms.

METHODS

Data were collected relating to a 12-month period, from September 2017 immediately following campaign launch, to the end of September 2018. The primary outcome was exposure to the #HoldthatSmile campaign on the different platforms through analysis of posts, measurement of audience reached and engagement. Secondary outcomes included demographics of user-types and content analysis of reactive comments on posts.

RESULTS

A total of 205 relevant posts with #HoldthatSmile were identified on Twitter (n=90, 43.9%), Facebook (n=64, 31.2%) and Instagram (n=51, 24.9%) with an overall calculated audience reach of 108,807 individuals. There were 1849 reactions across the three platforms. The percentage of reactions that generated comments was low at 3%, 6.1% and 5.7% for Twitter, Facebook and Instagram, respectively. Just over three-quarters of users were either Dental Surgeries (53%) or Professional Dental Bodies (28%) and the vast majority were from the United Kingdom. Overall, most comments were positive (46%, n=36) or neutral (44%, n=35) with only 10% (n=8) negative. The overriding theme was a person's name, with the user commonly typing a friend's name in order to bring their attention to the post.

CONCLUSION

There were a relatively low number of posts relevant to #HoldthatSmile on Twitter, Facebook and Instagram over the campaign's first 12 months. However, the majority of these did convey positive or neutral messages.

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.

The effectiveness of a bespoke mobile application in improving adherence with removable orthodontic retention over 12 months: A randomized controlled trial

INTRODUCTION

The primary aim was to analyze the effect of providing a mobile application (My Retainers) on adherence with removable retention.

METHODS

Eighty-four participants planned for thermoplastic retainers were randomly allocated to 2 groups. The intervention group was given access to a bespoke mobile application, while the control group was not given access. Baseline data were obtained at the removal of orthodontic appliances with follow-up at 3 months, 6 months, 9 months, and 12 months. The primary outcome was objectively assessed retainer wear recorded using a TheraMon microelectronic sensor (MC Technology GmbH, Hargelsberg, Austria). Secondary outcomes were stability and periodontal implications.

RESULTS

The objectively assessed wear time at 12 months was low in both groups, being marginally higher in the intervention (median, 3.09 h/d; interquartile range, 8.1) than the control group (median, 1.44 h/d; interquartile range, 9.22) with no between-group statistical difference (P = 0.30, 95% confidence interval [CI], -3.91 to 1.19). No statistically significant difference was identified between the groups in terms of stability and periodontal outcomes. Improvement in plaque scores (P <0.0001; 95% CI, -0.20 to 0.15) and bleeding on probing (P <0.0001, 95% CI, -0.23 to -0.12) was noted over time with no periodontal attachment loss detected over the study period.

CONCLUSIONS

Provision of the mobile application did not lead to improved adherence with thermoplastic retainer wear. Similarly, no benefit in respect of either occlusal stability or periodontal health was observed over the 12-month study period. Further novel approaches to improve adherence with retainer wear and oral hygiene measures are required.

Bullying in individuals with cleft lip and palate: A Twitter analysis

OBJECTIVES

This study aimed to evaluate bullying in individuals with cleft lip and/or palate (CLP) using Twitter analysis.

MATERIALS AND METHODS

By using Twitter's advanced search feature, the four selected keywords; "bully", "bullying", "bullied" and "teased" were searched along with the terms "cleft lip and palate", "cleft lip" and "cleft palate", respectively. A total of 1010 tweets meeting the criteria were selected. The data were evaluated qualitatively using thematic analysis and the determination of the themes were based on this analysis.

RESULTS

Most of the tweets were posted by a layperson (80.8%), while most of the tweets were categorised in the theme "criticism of bullying" (36%). The tweets were distributed according to their uploader status as irrelevant individuals (60.6%), CLP subjects (26.9%), family of CLP subjects' (12.5%). Of the 1010 tweets evaluated, 707 were identified as negative, while 90 were identified as neutral and 213 were identified as positive. No significant differences were detected in retweet and like numbers between negative, neutral and positive comments (P > .05).

CONCLUSIONS

Twitter is an important platform, in which the bullying victims with CLP and their families feel free to share their personal experiences of being bullied and how they feel about it, while the others are standing against bullying and promoting social support for these individuals.

A qualitative twitter analysis of the patient experience with invisible orthodontics; lingual braces versus invisalign

Objectives:

The aim of this qualitative study was to examine orthodontic patients’ thoughts and experiences about the invisible orthodontic treatment options – lingual braces and Invisalign – through the analysis of Twitter posts’ content.

Materials and Methods:

A software program was written for the data collection. The program consecutively collected the tweets posted over an 8-month period from Twitter’s publicly accessible database. Tweets that were written in the English language and contained any of the four keywords “Invisalign,” “lingualorthodontics,” “lingualbraces,” and “invisiblebraces” were collected. The tweets that included irrelevant or incoherent posts, professional advertisements, unclear/not applicable content, and reposts were excluded from the study. Two authors, with different experiences, independently read, and analyzed the tweets. Each applicable tweet was classified into one of the three categories: Positive, negative, and neutral for two study groups (Invisalign and lingual braces). Pearson Chi-square test was used to analyze the negative and positive tweet rates of the groups.

Results:

1176 of 2407 tweets were selected as applicable and analyzed by the authors. There was a statistically significant very good agreement between the two observers (Kappa = 0.933, P < 0.001). The negative comment rate (39%) and neutral comment rate (31.1%) in the lingual group were statistically higher than the Invisalign group (27.2% and 21.7%, respectively; P < 0.001). The positive comment rate in the Invisalign group was significantly higher (51.1%) compared to the lingual group (29.9%, P < 0.001).

Conclusion:

Orthodontic patients use social media to share their experiences and feelings about their treatment process. The applicable Tweet number and the positive Tweet rate in the Invisalign group were higher than the lingual braces group.

Is YouTube an adequate patient resource about orthodontic retention? A cross-sectional analysis of content and quality

INTRODUCTION

The study aimed to evaluate the content and quality of information offered by YouTube for patients seeking information related to orthodontic retainers.

METHODS

YouTube was searched using the keyword "orthodontic retainers" from Google Trends. From the first 120 results, 97 videos were selected to be analyzed. Videos were rated for quality by video information and quality index (VIQI) and the global quality scale (GQS). Videos were classified as low- and high-content groups using a 10-point score considering several retainer-related topics. Mann-Whitney U tests, chi-square tests, and Pearson correlation coefficients were used for statistical evaluations.

RESULTS

Most YouTube videos were uploaded by dentists/specialists (62.9%). We classified 12 videos as high content and 85 as low content. Instructions on the use of the orthodontic retainer was the most commonly covered topic (42.3%), followed by the effect on oral hygiene (38.1%), definition (37.1%), procedure of preparing orthodontic retainers (33.0%), and procedure of positioning (30.9%). A lower percentage of videos (6.2%) mentioned soft tissue irritation. The high-content video group had a significantly higher median value of GQS score and VIQI (P <0.001). The correlation between GQS and VIQI was strong (r = 0.698; P <0.01).

CONCLUSIONS

The content of YouTube videos for orthodontic retainers could not be considered as an adequate source of information for patients on orthodontic retainers. Most videos included instructions on the use of orthodontic retainers, but fewer videos mentioned the effect on speech performance and soft tissue irritations.

What are dental professionals posting on Facebook? A cross-sectional content analysis

OBJECTIVE

To profile the posts on open orthodontic Facebook groups and identify which communication strategies and media modalities generate the most engagement from users.

DESIGN

A cross-sectional content analysis.

SETTING

Facebook Internet-based search.

METHODS

Post data were collected over a one-month period from the 10 largest public orthodontic Facebook groups. Evaluation of group characteristics included membership levels, number of administrators, time each group had been in existence and growth rate of each group. The number of posts, the numbers and types of engagement (likes, emojis, comments, shares) and engagement rate were calculated. The communication strategies (e.g. case presentation, course promotion, etc.) and media modalities (e.g. plain text, photograph, etc.) were recorded.

RESULTS

The study identified 190,268 Facebook members from the 10 largest orthodontic Facebook groups (median 17,811; interquartile range [IQR] 11,977). The median time the groups had existed was six years (median 2175 days; IQR 2311 days) and the median number of new group members in the past month was 1257 (IQR 2773). The median number of new group members in the past month was 1257 (IQR 2773). There were 227 postings during the study period with 2546 engagements. The overall median number of engagements was 196 (IQR 445) and the engagement rate of posts was 1.3% overall. Posts relating to course promotion (n = 63, 28%) followed by product promotion (n = 42, 19%) were the most common. Case presentation style posts accounted for 15% (n = 35). The level of engagement was greater for posts that had a clinical component compared to posts that did not (P < 0.001). For media modality, posts that included a photograph had greater engagement (P < 0.001).

CONCLUSION

There are frequent posts on course and product promotion in orthodontic Facebook groups; however, these are associated with low levels of engagement. Posts that are clinically orientated and include photographs have higher levels of engagement.

Removable retention: enhancing adherence and the remit of shared decision-making

Patient adherence to removable retainer wear is integral to the long-term success of retention regimes. We discuss the factors influencing removable retainer wear, the methods of gauging wear levels, approaches to enhance adherence and the quality of online available information concerning retention. The potential value of patient involvement in approaches to retention within a shared decision-making framework and motivational interviewing are also highlighted.

The rationale for orthodontic retention: piecing together the jigsaw

Retaining teeth in their corrected positions following orthodontic treatment is one of the most challenging aspects of orthodontic practice. Despite much research, the rationale for retention is not entirely clear. Teeth tend to revert to their pre-treatment positions due to periodontal and gingival, soft tissue, occlusal and growth factors. Changes may also follow normal dentofacial ageing and are unpredictable with great variability. In this overview, each of these factors are discussed with their implications for retention, along with adjunctive procedures to minimise relapse. The state of current knowledge, methods used to assess relapse, factors regarded as predictive of or associated with stability as well as overcorrection are outlined. Potential areas requiring further investigation are suggested. The way in which the clinician may manage current retention practice, with a need for individualised retention plans and selective retainer wear, is also considered.

Comparison of post-treatment changes with and without retention in adolescents treated for maxillary impacted canines-a randomized controlled trial

Objective

To evaluate whether retention is needed after orthodontic treatment of impacted maxillary canines.

Trial design

Two-arm parallel group single-centre randomized controlled trial.

Materials and methods

Sixty-three patients, 39 girls and 24 boys, were recruited to the study. The inclusion criteria were patients with at least one impacted or unerupted maxillary canine, and moderate irregularity of the maxillary six anterior teeth according to Little’s index (LI). After gaining informed consent from the patient and their custodians, the patients were randomized to one of two groups, i.e. to a non-retention group or a retention group. The randomization process was prepared and carried out by an independent person not involved in the trial and the randomization used blocks of 20 (10 + 10). Primary outcomes were changes in single contact point discrepancy, and LI measured on digitalized three-dimensional study casts 1-year post-treatment. The study casts were anonymized before assessment and the changes were blinded for the assessor. Data were evaluated on an intention-to-treat basis. Thus, all randomized patients were incorporated into the final analysis. In the non-retention group a 10-week interim period was used to detect patients who eventually have a relapse immediately after treatment. If so, the patient got the arch-wire reinserted. Most patients in the retention group received a vacuum-formed retainer and pretreatment spacing cases got a bonded retainer.

Results

Mean irregularity change was 0.4 mm in the retention and 1.3 mm in the non-retention group (P < 0.001). Maximum change was 2.5 mm in the retention and 3.2 mm in the non-retention group (P < 0.001). Most changes in the non-retention group occurred during the 10-week interim period. In the non-retention group, one patient developed contact point discrepancy of >2 mm during the interim period and was realigned.

Harms

One patient met the stopping guideline criteria. This patient had the arch wire reinserted for 2 months. After realignment, the patient received a retention appliance.

Limitations

The trial was a single-centre study and short-term changes were evaluated.

Conclusions

Changes between the retention and the non-retention group were statistically but not clinically significant. Since satisfactory clinical results 1-year post-treatment were found in the non-retention group, retention does not appear to be needed. The 10-week interim period was useful in detecting patients who might have a relapse immediately after treatment.

Trial registration

The trial was not registered.

Invisalign treatment from the patient perspective: A Twitter content analyses

Background

Understanding patient perspective is a key factor in improving treatment satisfaction. The aim of the present study is to qualitatively describe the content of Twitter posts related to the treatment with Invisalign in order to get a better understanding of patient experience.

Material and Methods

Tweets were prospectively collected during a period of four weeks from public available posts on Twitter using Awario™ a bespoke social media monitoring tool. After applying the pertinent inclusion and exclusion criteria the selected posts were analysed by three investigators using thematic analysis. Specific themes and subthemes were developed.

Results

A total of 1564 tweets were analysed; three mayor themes were identified: Pre-treatment related, Treatment related and Patient/clinician relationship. Pre-treatment posts were mainly positive and underlined patients' expectations, while in the treatment phase an almost equal number of positive and negative posts were found. The positive post were about the satisfaction with treatment and the improvement of self-esteem. The negative ones were related to pain, compliance, the impact on diet and pronunciation.

Conclusions

The present study provides a better understanding of patients' experience during clear aligners treatment. Increasing the awareness of the clinicians can improve their ability to face problems related to the orthodontic treatment and to provide to their patients better professional advices and counselling. Key words:Social media, twitter, clear aligners, Invisalign, orthodontics.

Determining the impact of orthodontic patients' characteristics on their usage and preferences of social media

Objective

This study aims to assess the impact of orthodontic patients' characteristics on their usage and personal preferences of social media.

Methods

We developed a descriptive cross-sectional study. The questionnaire contained demographic data and questions about the usage of social media and their preferred platforms. The validity and reliability of the questionnaire were examined. The final Arabic version was adopted, and Google Drive was used to conduct the survey. The survey link was sent to the general public via different social media platforms and applications.

Results

A total of 477 respondents participated in this study, which included 274 women and 203 men. Significant variation in the use of social media was observed between the genders. The use of Twitter, Snapchat, and YouTube was significantly higher in the 21–30-year-old group than in the other groups. Instagram was favoured by the 13–20-year-old group, while WhatsApp was most frequently used by those aged around 40 years. Social media usage was significantly more apparent among university graduates in both the orthodontic and non-orthodontic groups. The use of Twitter, Snapchat, YouTube, Instagram, and WhatsApp was significantly more common in the medium-income group than in any other group. Snapchat was the most commonly used platform across both groups.

Conclusion

Our study revealed that Twitter, Snapchat, and YouTube were the preferred social media applications for the middle-aged group. The use of Instagram was greatest in the teenage group, while WhatsApp was favoured by the older groups. Social media usage was most prevalent among university graduates, regardless of whether they were orthodontic or non-orthodontic patients.

The Impact of the COVID-19 Epidemic on Orthodontic Patients in China: An Analysis of Posts on Weibo

Background: During the COVID-19 pandemic, many dental care services including orthodontic practice were suspended. Orthodontic patients turned to social media platforms to communicate, share experiences, and look for solutions. Our study aimed to investigate the attitudes and perspectives of orthodontic patients during the COVID-19 epidemic in China by analyzing orthodontics-related posts on Sina Weibo (a Chinese counterpart of Twitter). Materials and Methods: Potentially eligible posts on Sina Weibo platform were collected between December 30, 2019, and April 18, 2020. Posts related to both orthodontics and COVID-19 were included and then coded and classified into specific appliances and themes. Geographic and temporal distributions of the included posts were analyzed. In addition, time-lagged cross correlation was performed to explore the association between the number of daily posts and daily new COVID-19 cases/deaths in China. Chi-square tests were employed to compare the differences between fixed appliances and aligners in problems/difficulties and feelings during the epidemic. Results: Of the 28,911 posts identified, 4,484 were included in the analysis. The most frequently mentioned themes were appointments (n = 2,621, 58.5%), negative feelings (n = 2,189, 48.8%), and problems/difficulties (n = 1,155, 25.8%). A majority of posts were tweeted in regions with high levels of economic development and population density in eastern China and from February to March. The number of daily posts had a significantly positive correlation with daily new COVID-19 cases/deaths in China (P < 0.05). Compared with clear aligners, patients with fixed appliances reported more problems/difficulties (P < 0.001) and negative feelings (P < 0.001), but fewer positive feelings (P < 0.001). Conclusions: The analysis of Weibo posts provided a timely understanding of the impact of COVID-19 on orthodontic patients. Delayed appointments were their greatest concern, and negative feelings and untreated orthodontic problems increased during the suspension of dental care services. However, patients with clear aligners reported fewer negative feelings and problems than those with fixed appliances. The findings highlighted the need to consider both treatment- and psychology-related issues of orthodontic patients and how to handle them appropriately during the epidemic.

Development of 'My Retainers' mobile application: Triangulation of two qualitative methods

OBJECTIVE

Diligent wear of removable orthodontic retainers requires prolonged adherence and is invariably necessary to preserve optimal results. Patient-informed behaviour-change interventions represent a promising and novel means of enhancing adherence to removable retainer wear. The aim of this study was to describe the development of a patient-informed mobile application designed to enhance retainer wear.

METHODS

App development encompassed consideration of participant preferences, social media posts, available interventions and behaviour change theories. Qualitative methods including analysis of publicly-available retainer-related posts on Twitter (n = 827) and one-to-one interviews were undertaken. Audio-recorded one-to-one interviews were undertaken to identify patient preferences in relation to features, content and design of the application. A criterion-based purposive sample of participants wearing vacuum-formed retainers for at least 4 years was used (n = 15). Thematic analysis of transcribed data was undertaken. These data were triangulated to inform design and content of the application.

RESULTS

The need to facilitate communication with the treating clinician, responsive reminder and tracking systems, and access to useful and engaging written and visual information, in addition to other personalised and interactive features were considered important. Concerns related to retainer wear shared on Twitter informed an exhaustive list of frequently-asked questions. Application features were mapped to relevant theoretical constructs. Determinants of existing behavioural change theories were also used to link application features to retainer wear and maintenance.

CONCLUSIONS

A holistic process involving both patient and professional input can be useful in informing the development of mobile applications. The orthodontic application ("My Retainers") will undergo further scrutiny in relation to its effectiveness in inducing behavioural change and concerning patient experiences prior to finalisation.

Evaluation of the effectiveness of a tailored mobile application in increasing the duration of wear of thermoplastic retainers: a randomized controlled trial

Background

The ‘My Retainers’ mobile application is a patient-informed intervention designed to enhance removable retainer wear and associated patient experiences during the retention phase.

Objectives

To evaluate the effect of receiving the ‘My Retainers’ application on objectively assessed thermoplastic retainer (TPR) wear time, stability, periodontal outcomes, patient experiences, and knowledge related to retainers.

Materials and methods

Eighty-four participants planned for removable retention with TPRs were assigned either to receive the ‘My Retainers’ application or to control not receiving electronic reminders during the 3-month period. Randomization was based on computer-generated random numbers and allocation was concealed using opaque, sealed envelopes. The primary outcome was objectively assessed retainer wear recorded using an embedded TheraMon® micro-electronic sensor. Secondary outcomes, including irregularity of the maxillary and mandibular incisors, plaque levels, bleeding on probing and probing depth, were assessed at baseline and 3-month follow-up; and analysed using a series of mixed models. Experiences and knowledge related to orthodontic retainers were recorded using questionnaires. The outcome assessor was blinded when possible.

Results

Receipt of the mobile application resulted in slightly higher median wear time (0.91 hours/day); however, this difference was not statistically significant (P = 0.56; 95% confidence interval [CI]: −2.19, 4.01). No significant differences were found between the treatment groups in terms of stability (P = 0.92; 95% CI: −0.03, 0.04), plaque levels (P = 0.44; 95% CI: −0.07, 0.03), bleeding on probing (P = 0.61; 95% CI: −0.05, 0.03) and probing depth (P = 0.79; 95% CI: −0.09, 0.07). Furthermore, similar levels of patient experiences (P = 0.94) and knowledge related to retainers (P = 0.26) were found. However, marginally better levels of knowledge were identified in the intervention group. No harms were observed.

Limitations

A relatively short follow-up period with the study confined to a single-center in a university-based hospital.

Conclusions

Provision of the bespoke ‘My Retainers’ application did not lead to an improvement in adherence with TPR wear over a 3-month follow-up period. Further refinement and research are required to develop and investigate means of enhancing adherence levels.

Factors influencing adherence to vacuum-formed retainer wear: A qualitative study

Objective:

To explore factors influencing adherence to vacuum-formed retainer wear over a minimum period of four years.

Design:

A qualitative study based on a randomised controlled trial assessing the effectiveness of orthodontic retainers.

Setting:

Institute of Dentistry, Queen Mary University of London.

Participants:

Fifteen participants wearing vacuum-formed retainers for at least four years.

Methods:

One-to-one semi-structured interviews were undertaken on a criterion-based purposive sample of participants wearing vacuum-formed retainers. The interviews were audio-recorded, transcribed verbatim and analysed using Framework Methodology.

Results:

High self-reported levels of adherence in the early stages of retention were linked to a desire to maintain orthodontic outcomes and the negative perception of potential post-treatment changes. However, adherence typically reduced over time due to a combination of factors including the negative impact of retainers on quality of life and pragmatic issues related to retainer wear. Network support was found to be important in the short and long term, with instances of self-directed wear and negative beliefs concerning the importance of retainer wear and predisposition to post-treatment changes. Lack of follow-up appointments and immaturity of participants prompted independent decisions to cease retainer wear.

Conclusions:

Six key influencers of prolonged adherence with vacuum-formed retainer wear were identified. Future strategies to improve adherence should account for these while also being responsive to time elapsed since debond and patient age.

Social media and orthodontic treatment from the patient’s perspective: a systematic review

Background

Social media are one of the most common and easily accessible ways of gaining information about orthodontic treatment.

Objective

The main objective of this study was to systematically search the literature and determine the various aspects of the interrelationship between social media and orthodontics from the patient’s perspective.

Search methods

Electronic database searches of published and unpublished literature were performed. The reference lists of all eligible articles were hand-searched for additional studies.

Selection criteria

Randomized clinical trials (RCTs), prospective, retrospective, and cross-sectional studies were included.

Data collection and analysis

Study selection, data extraction, and risk of bias assessment were performed individually and in duplicate by the first two authors.

Results

One RCT, three retrospective, and four cross-sectional studies were deemed as eligible for inclusion in this review. The studies included patient’s statements in social media or results from questionnaires given to patients. The social media reported were with order of frequency: Twitter, YouTube, Facebook, Google+, Pinterest, and Instagram. The feelings the patients expressed seemed to be more positive than negative: enthusiasm, self-esteem and pleasure, excitement about the aesthetic result, excitement after braces removal but also antipathy, annoyances, reduced self-esteem, and impatience for removing mechanisms. In addition, one study referred to bullying through Twitter.

Limitations

The high amount of heterogeneity precluded a valid interpretation of the results through pooled estimates.

Conclusions and implications

This systematic review demonstrated that information about orthodontics, how the patient feels, and other psychosocial facets are spread through social media. It is intuitive that research relating to the effects and impact of orthodontic interventions should account not only for the physical impacts of treatment but also to encompass patient-centered outcomes.

Registration

The protocol of this study was not registered in publicly assessable database.

Protein-repellent and antibacterial effects of a novel polymethyl methacrylate resin

OBJECTIVES

Heat-cured resins are commonly used in orthodontics; however, there is a high incidence of caries, periodontal diseases and denture-induced stomatitis. The objectives of this study were to: (1) develop a new bioactive polymethyl methacrylate (PMMA) resin containing 2-methacryloyloxyethyl phosphorylcholine (MPC) and quaternary ammonium dimethylaminohexadecyl methacrylate (DMAHDM), and (2) investigate the effects on mechanical properties, protein-repellency and antibacterial properties.

METHODS

MPC and DMAHDM were mixed into a commercial acrylic resin (Nature Cryl™ MC). Mechanical properties were measured in three-point flexure. Surface roughness was assessed using atomic force microscopy (AFM). Protein adsorption onto the PMMA resin was measured using a micro bicinchoninic acid (BCA) method. A human saliva microcosm model was used to investigate the live/dead staining and metabolic activity of the biofilms.

RESULTS

Incorporation of 3% MPC and 1.5% DMAHDM into PMMA resin achieved protein repellent and antibacterial capabilities, without compromising the mechanical properties. PMMA resin with 3% MPC + 1.5% DMAHDM had protein adsorption that was 1/6 that of a commercial control (p < 0.05). The PMMA resin with 3% MPC + 1.5% DMAHDM had much greater reduction in biofilm growth than using MPC or DMAHDM alone (p < 0.05).

CONCLUSIONS

A bioactive PMMA resin with a combination of strong protein-repellent and antibacterial capabilities was developed for the first time. The new resin greatly reduced the biofilm growth and metabolic activity, without compromising its mechanical properties.

SIGNIFICANCE

Novel PMMA resin is promising for applications in orthodontic retainers and orthodontic appliances to reduce biofilm activity and protein adsorption around the resin.

Experiences Of Individuals Concerning Combined Orthodontic and Orthognathic Surgical Treatment: A Qualitative Twitter Analysis

OBJECTIVE

The aim of this qualitative study was to analyze the content of posts on Twitter in order to gain an in-depth understanding of patients' thoughts and experiences surrounding orthognathic surgical treatment.

MATERIALS AND METHODS

Using the Twitter search function, with the keywords "jaw surgery," the 1,000 most recent posts on Twitter with relevance to a combined orthodontic and orthognathic surgical treatment were extracted. After applying relevant inclusion and exclusion criteria, the selected posts were analyzed using thematic analysis by 2 independent investigators. Distinct themes and subthemes were developed.

RESULTS

A total of 689 posts were analyzed; the 3 main themes identified in relation to orthognathic surgery were preoperative engagement, postoperative difficulties, and posttreatment satisfaction. Twelve subthemes were also identified, expressing issues such as anticipation or apprehension of the surgical procedure, postoperative pain and edema, dietary restrictions and weight loss, paresthesia, depression, and satisfaction with improvements in appearance and self-confidence. The 6 terms most frequently used in tweets were "recovery," "braces," "swollen," "eat," "liquid diet," and "pain."

CONCLUSIONS

The findings from the present study can increase the awareness of clinicians involved in the combined orthodontic and orthognathic surgical treatment of patients with dentofacial deformities, allowing them to better educate and counsel their patients throughout the entire treatment process.
