YouTube as a source of information about pulpotomy and pulp capping: a cross sectional reliability analysis

Assessment of the quality of oral biopsy procedure videos shared on YouTube

OBJECTIVE

The aim of this study was to assess the quality of free-to-access videos on oral biopsy procedures on the YouTube platform.

MATERIALS AND METHODS

We conducted a search on YouTube using the term "oral biopsy" and selected the first 100 videos in order of relevance. The following exclusion criteria were applied: language other than English, videos that did not cover oral biopsy techniques, videos on nonhuman specimens, postoperative instructions, personal experiences, exfoliative cytology, or "brush biopsy." Forty-seven selected videos were classified based on their duration, country of origin, date of upload to the system, author, information source and number of views, and likes and dislikes. Video quality was analyzed using DISCERN, the Global Quality Scale (GQS), and the Video Information and Quality Index (VIQI).

RESULTS

The majority (78.7%) of analyzed videos were uploaded by dentists, originating from India (48.9%), with a mean duration of 11.8 min (SD, 20.4), with 104.5 likes (SD, 186.4) and 7.1 dislikes (SD, 10.55). The mean values for DISCERN, GQS, and VIQI were 1.3 (SD, 0.52), 2.1 (SD, 1.04), and 9.62 (SD, 1.69), respectively.

CONCLUSION

The majority of videos on oral biopsy published on YouTube are of low quality.

Examination of Information Quality on Public Instagram Profiles Regarding Botulinum Toxin for Bruxism: A Study in São Paulo State, Brazil

Background

Currently, social media emerges as a swift and efficient channel for disseminating knowledge in dentistry; however, it is imperative to assess whether this information aligns with scientific evidence. This study aims to evaluate the quality of information found on public Instagram profiles in São Paulo State, Brazil, regarding the utilization of botulinum toxin (BTx) for bruxism treatment.

Material and Methods

The data were categorized into three qualitative groups: information pertaining to bruxism diagnosis, treatment options for bruxism, and the application of BTx for bruxism. Following the selection of pertinent publications, 50 public profiles were included in the analysis. The publications were assessed utilizing the Global Quality Scale (GQS).

Results

A total of 20,546 posts were tallied across the 50 profiles, with 230 relating to bruxism diagnosis, 166 discussing bruxism treatment options, and 78 mentioning the use of BTx for bruxism. Of these 78 posts addressing BTx for bruxism, 61% did not align with current scientific references, while 39% did. GQS analysis disclosed predominantly "poor quality" content (GQS = 2).

Conclusions

It is concluded that the themes of bruxism and BTx are frequently broached on public Instagram profiles, yet the quality of the available information is generally subpar and often lacks scientific substantiation. Key words:Botulinum Toxins, Type A; Bruxism; Online Social Networking; Sleep Bruxism.

Is it safe to learn about vital pulp capping from YouTube™ videos? A content and quality analysis

AIM

To evaluate YouTube videos on vital pulp capping (VPC) for content, quality, source, usefulness, and reliability.

MATERIALS AND METHODS

This study assessed 249 English-language videos on vital pulp therapy using the Total Content Score (TCS), Video Information and Quality Index (VIQI), Global Quality Scale (GQS), Journal of the American Medical Association (JAMA) score and modified DISCERN score. Videos were categorized based on communication quality, duration, likes and dislikes, views, source, and video type. Of the videos analyzed, 22.1% met the inclusion criteria. Data were analyzed using Shapiro-Wilk, Kruskal-Wallis, and post hoc Bonferroni tests. Sperman's correlation, Kendal tau tests for correlations, and Fisher's exact test were used to assess associations between categorical variables.

RESULTS

The study identified significant correlations between various parameters. A higher TCS was correlated with increased VIQI (p = 0.005) and GQS scores (r = 0.685, p < 0.05). A moderate positive correlation was found between GQS scores and TCSs (r = 0.577, p < 0.05). VIQI scores were significantly and positively correlated with TCS (r = 0.573, p < 0.05) and comment count (r = 0.306, p < 0.05). JAMA scores were positively correlated with upload time (r = 0.304, p < 0.05), comment count (r = 0.337, p < 0.05), and likes (r = 0.301, p = 0.05).

CONCLUSIONS

YouTube videos provided low-to-average quality VPC information and tended to be inaccurate. Therefore, public videos may be incorrect, incomplete, and low-quality. Clinicians and patients should seek reliable information from specialists.

Quality of Patient-Centered eHealth Information on Erosive Tooth Wear: Systematic Search and Evaluation of Websites and YouTube Videos

BACKGROUND

Due to the declining prevalence of dental caries, noncarious tooth defects such as erosive tooth wear have gained increased attention over the past decades. While patients more frequently search the internet for health-related information, the quality of patient-centered, web-based health information on erosive tooth wear is currently unknown.

OBJECTIVE

This study aimed to assess the quality of patient-centered, web-based health information (websites and YouTube videos) on erosive tooth wear.

METHODS

German-language websites were systematically identified through 3 electronic search engines (google.de, bing.de or yahoo.de, and duckduckgo.com) in September 2021. Eligible websites were independently assessed for (1) technical and functional aspects via the LIDA instrument, (2) readability via the Flesch reading-ease score, (3) comprehensiveness of information via a structured checklist, and (4) generic quality and risk of bias via the DISCERN instrument by 2 different reviewers. An overall quality score (ie, higher scores being favored) generated from all 4 domains was used as the primary outcome. Quality scores from each domain were separately analyzed as secondary outcomes and compared by the Friedman test. The effect of practice-specific variables on quality scores of websites from private dental offices was assessed using generalized linear modeling. Eligible YouTube videos were judged based on (1) the comprehensiveness of information, (2) viewers' interaction, and (3) viewing rate. The comprehensiveness of information was compared between websites and YouTube videos using the Wilcoxon rank-sum test.

RESULTS

Overall, 231 eligible websites and 7 YouTube videos were identified and assessed. The median overall quality of the websites was 33.6% (IQR 29.8%-39.2%). Secondary outcome scores amounted to 64.3% (IQR 59.8%-69.0%) for technical and functional aspects, 40.0% (IQR 34.0%-49.0%) for readability, 11.5% (IQR 3.9%-26.9%) for comprehensiveness of information, and 16.7% (IQR 8.3%-23.3%) for generic quality. While the comprehensiveness of information and generic quality received low scores, technical and functional aspects as well as readability resulted in higher scores (both Padjusted<.001). Regarding practice-specific variables, websites from private dental offices outside Germany (P=.04; B=-6.64, 95% CI -12.85 to -0.42) or from dentists who are a dental society member (P=.049; B=-3.55, 95% CI -7.09 to -0.01) resulted in lower readability scores (ie, were more difficult to read), while a shorter time since dentists' examination resulted in higher readability scores (P=.01; B=0.24 per year, 95% CI 0.05-0.43). The comprehensiveness of information from YouTube videos was 34.6% (IQR 13.5%-38.5%). However, the comprehensiveness of information did not vary between websites and YouTube videos (P=.09). Additionally, viewers' interaction (1.7%, IQR 0.7%-3.4%) and viewing rates (101%, IQR 54.6%-112.6%) were low.

CONCLUSIONS

The quality of German-language, patient-centered, web-based information on erosive tooth wear was limited. Especially, the comprehensiveness and trustworthiness of the available information were insufficient. Web-based information on erosive tooth wear requires improvement to inform patients comprehensively and reliably.

Assessment of reliability and information quality of YouTube videos about root canal treatment after 2016

Background

This study aimed to assess and update the content, reliability, and information quality of content related to root canal treatment (RCTx) on YouTube and evaluate the correlation between each evaluation index.

Methods

YouTube was searched using two terms related to RCTx (“root canal and endodontic treatment”). A total of 240 videos (120 for each search term) were screened. Exclusion criteria were as follows: no sound or visuals, non-English, irrelevant to the search term, longer than 15 min, duplicate, or old (uploaded before 2016). After exclusion, 50 videos of “root canal treatment” and 45 videos of “endodontic treatment” were analyzed. Video length, total number of views, likes, dislikes, comments, and days since upload were recorded using descriptive video data. Viewers’ interaction, reliability and information quality of the video, and quality of video content were measured using nondescriptive video data. The interaction index and video power index were used for viewer interactions, and the modified DISCERN index, JAMA criteria, and Global Quality Score were used to assess the reliability and information quality of the video. The quality of the video content was measured using the completeness score.

Results

The videos of the “root canal treatment” group had a significantly higher completeness score for the etiology and symptoms (p < 0.05), and videos of the “endodontic treatment” group showed a higher interaction index, completeness score for the procedure (p < 0.05). Videos for dentists had significantly higher completeness scores for the procedure, while videos for laypersons had higher completeness scores for etiology, anatomy, symptoms, and prognosis (p < 0.05). Furthermore, the total completeness score and the interaction index of the videos for laypersons were significantly higher (p < 0.05). The videos uploaded by the university had a significantly higher modified DISCERN index (p = 0.044), and the JAMA score was significantly higher in the commercial group (p = 0.001).

Conclusions

Although the accuracy of videos related to RCTx was higher in videos by universities and professionals, the total completeness of YouTube videos was low regardless of the video source. Therefore, professionals should be responsible for providing more accurate and reliable videos.

Is the YouTube™ a useful resource of information about orthognathic surgery?: A cross-sectional study

PURPOSE

YouTube™ has become a widely used resource of information about health-related topics nowadays. This cross-sectional study has aimed to analyze the content and quality of YouTube™ videos on orthognathic surgery.

METHODS

In our study, six orthognathic surgery-related keywords (Le Fort I osteotomy, sagittal split osteotomy, jaw surgery, jaw correction surgery, orthodontic surgery, and orthognathic surgery) were used to search on YouTube™. Only the videos in English, which had visually and audibly acceptable quality and were mainly about orthognathic surgery, were chosen from the videos. A total of 360 videos were selected, the top 60 videos for each search term, and sorted according to view count. Of these videos, the first 60 videos were analyzed. Video source (independent or educational), duration, number of views, likes, and dislikes were recorded for each video. Moreover, two impartial observers evaluated the visibility, popularity, quality, usefulness, and reliability of the videos.

RESULTS

41 of 60 videos were of independent sources while 19 of them were of educational origin. Information content of the videos was found to be insufficient. No significant difference was determined between independent and educational videos in terms of popularity, visibility, usefulness and quality analysis of the videos (p > 0.05), but a significant difference was found in terms of reliability values (p < 0.05).

CONCLUSION

It can be said that YouTube™ videos were not a reliable and accurate enough source of information when evaluated in terms of orthognathic surgery-related content and quality. Therefore, the information content provided by specialists and health institutions, in particular, should be increased in number, thereby making access to better quality information on orthognathic surgery easy for patients.
