Evaluating the Dental Caries-Related Information on Brazilian Websites: Qualitative Study

Examination of the reliability and readability of Chatbot Generative Pretrained Transformer's (ChatGPT) responses to questions about orthodontics and the evolution of these responses in an updated version

INTRODUCTION

This study aimed to assess the reliability and readability of Chatbot Generative Pretrained Transformer (ChatGPT) responses to questions about orthodontics and the evolution of these responses in an updated version.

METHODS

Frequently asked questions about orthodontics by laypeople on Web sites were determined using the Google Search Tool. These questions were asked to both ChatGPT's March 23 version and May 24 version on April 20, 2023, and July 12, 2023, respectively. Responses were assessed for readability and reliability using the Flesch-Kincaid and DISCERN tests.

RESULTS

The mean DISCERN value for general questions was 2.96 ± 0.05, 3.04 ± 0.06, 2.38 ± 0.27, and 2.82 ± 0.31 for treatment-related questions; the mean Flesch-Kincaid Reading Ease score for general questions was 29.28 ± 8.22, 25.12 ± 7.39, 47.67 ± 10.77, and 41.60 ± 9.54 for treatment-related questions; mean Flesch-Kincaid Grade Level for general questions was 14.52 ± 1.48 and 14.04 ± 1.25 and 11.90 ± 2.08 and 11.41 ± 1.88 for treatment-related questions; in first and second evaluations respectively (P = 0.001).

CONCLUSIONS

In the second evaluation, the reliability of the answers given to general questions and treatment-related questions increased. However, in both evaluations, the reliability of the answers was found to be moderate according to the DISCERN tool. On the second evaluation, Flesch Reading Ease Scores for both general questions and treatment-related questions decreased, meaning that the readability of the new response texts became more difficult. Flesch-Kincaid Grade Level results were found at the college graduate level in the first and second evaluations for general questions and at the high school level in the first and second evaluations for treatment-related questions.

Quality and Readability Assessment of Web-based Arabic Health Information on Early Childhood Caries

Background

Patients are increasingly using the internet for searching health-related information. However, the quality and readability of the information available on the internet need to be assessed. To date, no study has assessed the quality and readability of web-based Arabic health information on early childhood caries.

Objectives

To evaluate the quality and readability of patient-oriented online Arabic health information regarding early childhood caries.

Materials and Methods

For this infodemiological study, the Google and Yahoo search engines were searched using specific Arabic terms for early childhood caries, and the top 100 searches from both search engines were considered. Eligible websites were categorized in terms of affiliation as commercial, health portal, dental practice, professional, and journalism. The quality of the websites was assessed using the QUality Evaluation Scoring Tool (QUEST), and readability using the Gunning Fog index (GFI).

Results

A total of 140 websites were included after applying the exclusion criteria, of which 50.7% websites were of journalism. The majority of the websites (70%) had an overall low-quality level, with a QUEST score <10. The quality of websites retrieved from Google searches was of significantly higher quality than those from Yahoo (P < 0.0001). More than half (51.4%) of the websites had good readability, with a GFI score ≤8. Journalism websites had a significantly higher proportion of websites with poor readability level (62%) compared with other affiliations (P = 0.0072).

Conclusion

The web-based Arabic information regarding early childhood caries is currently of low quality and moderate readability level, thereby indicating a need for improving such patient-facing content.

Dental Practice Websites in Germany-How Do They Inform about Fluoridation?

Fluoridation (Fl) is effective in preventing caries; however, it is unclear to what extent its use is counteracted by misinformation on the internet. This study aimed to evaluate the information provided on professional websites of German dental practices regarding fluoridation. A systematic search was performed by two independent examiners, utilizing three search engines, from 10 September 2021 to 11 December 2021. Modified, validated questionnaires (LIDA, DISCERN) were used to evaluate technical and functional aspects, generic quality, and risk of bias. Demographic information and statements about Fl were also collected. The intra- and inter-rater reliability assessments were excellent. Of the 81 websites analyzed, 64 (79%) mentioned Fl, and 31 (38%) indicated it as a primary focus. Most websites met at least 50% of the LIDA (90%) and DISCERN criteria (99%), indicating that the general quality was good. Thirty (37%) of the websites explained the impact of Fl, and forty-five (56%) indicated an opinion (for/against) on Fl. The practice location and the clinical focus were not associated with the overall quality of websites. Only a minority of websites explained the effects of Fl. Taken together, this study highlights that there is a distinct lack of good-quality information on FL.

Does information about MIH on dental homepages in Germany offer high quality? A systematic search and analysis

PURPOSE

The internet is increasingly used to seek health information. A dental condition of increasing concern and public interest is molar incisor hypomineralisation (MIH), why we evaluated the information quality of German dentists 'websites on the topic of MIH.

METHODS

A systematic search was performed by two independent investigators using three search engines. The information content of websites on MIH and technical, functional aspects, overall quality, and risk of bias were assessed using validated instruments (LIDA, DISCERN). Practice-related characteristics (practice type, specialization, setting, number and mean age of dentists) were recorded, and associations of these characteristics with websites' overall quality were explored using multivariable linear regression modelling.

RESULTS

70 sites were included. 52% were multipractices in urban areas (49%). The most common age group was middle-aged individuals (41-50 years). The average number of dentists/practice was 2.5. The majority met more than 50% of the DISCERN and LIDA criteria (90%, 91%). The MIH definition was frequently used (67%), MIH symptoms were described (64%), and 58% mentioned therapies. The prevalence of MIH was mentioned less frequently (48%). MIH example photographs were rarely shown (14%). In multivariable analysis, most practice-related factors were not significant for overall site quality. Only chain practices had slightly higher quality in this regard (2.2; 95% CI of 0.3-4.1).

CONCLUSIONS

MIH is mentioned on a large proportion of dentists' websites. Overall technical, functional, and generic quality was high. Risk of bias is limited. While most websites provided a basic definition of MIH and its symptoms, important information for patients was missing.

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.

Clarity of publications on HPV in Instagram profiles of official health agencies in Brazil

The study analyzed the clarity of publications on human papillomavirus (HPV) in the Instagram profiles of official Brazilian health agencies. An infodemiological study analyzed publications on HPV in the 81 Instagram profiles selected from the Health Ministry, States' Health Departments, and dental councils and associations. The following data were collected: classification of content, type of profiles, type of media, how the content was addressed, number of posts, frequency, likes, comments, viewings, and hashtags, and how the HPV vaccine was addressed. The clarity of the educational publications was assessed using the Brazilian version of the Clear Communication Index (BR-CDC-CCI). Data analysis was performed with Spearman's correlation and the Mann-Whitney test (p < 0.05). A total of 504 publications on HPV were found. The average number of likes was 528.3 (SD = 2388.2) and the average BR-CDC-CCI score was 67.1 (SD = 14.1). The quality and clarity of the information was considered adequate (BR-CDC-CCI score ≥ 90) in 6.9% of the publications. A weak positive correlation was found between the number of likes and both the BR-CDC-CCI score (r = 0.195) and number of posts (r = 0.124). Publications from the Health Ministry had a significantly higher BR-CDC-CCI score (72.9) compared to the other profiles analyzed (p = 0.01). Most publications concerned government actions, had low engagement, and written educational information was of low clarity and quality. However, the effort to reach the population was evident, with an increase in publications over the years.

Quality and readability of web-based information on dental caries in Arabic: an infodemiological study

BACKGROUND

Web-based information on dental caries in Arabic remains poorly understood. This study aimed to assess the quality and readability of web-based information about dental caries in Arabic.

METHODS

The first 100 websites in Arabic about dental caries were retrieved from Google and Bing using common terms. The websites were classified and evaluated for quality based on the Journal of the American Medical Association (JAMA) benchmark criteria, the DISCERN tool, and the presence of the Health on the Net Foundation Code of Conduct (HONcode). Readability was assessed using online readability indexes.

RESULTS

A total of 102 Arabic websites were included. The JAMA benchmark score was low (m = 0.36, SD = 0.56), with 67.7% failing to meet any of the JAMA criteria. The DISCERN total score mean was 37.68 (SD = 7.99), with a majority (67.65%) of moderate quality. None of the websites had the HONcode. Readability was generally good, with 52.94% of websites having a Flesch-Kincaid Grade Level (FKGL) < 7, 91.18% having a Simple Measure of Gobbledygook (SMOG) < 7, and 85.29% having a Flesch reading ease (FRE) score ≥ 80. There was a positive correlation between JAMA and DISCERN scores (p < 0.001). DISCERN scores were positively correlated with the number of words (p < 0.001) and sentences (p = 0.004) on the websites. However, JAMA or DISCERN scores were not correlated with FKGL, SMOG, or FRE scores (p > 0.05).

CONCLUSIONS

The quality of Arabic dental caries websites was found to be low, despite their readability. Efforts are needed to introduce more reliable sources for discussing dental caries and treatment options on sites aimed at Arabic populations.

Web-Based Information on the Treatment of Dental Hypomineralization

PURPOSE

To categorise and evaluate the quality and readability of the web-based information about the treatment of the variety of forms of dental hypomineralization.

METHODS

An internet search using two different search terms regarding treating dental hypomineralization was conducted using the Google search engine. The first 100 websites from each search were analysed. Data recorded included DISCERN instrument scores, the Journal of the American Medical Association (JAMA) benchmarks, and the Health on the Net seal (HON). Flesch Reading Ease Scores (FRES), Flesch-Kincaid Grade Level (FKGL), the Simplified Measure of Gobbledygook Index (SMOG), and the Coleman-Liau index were calculated to assess readability.

RESULTS

A search for "Treatment of hypomineralized teeth" on Google yielded 48,500 results. After excluding irrelevant websites, only 25 were evaluated based on affiliation with universities/medical centers, non-profit organizations, commercial entities, or government agencies. The majority of the content was medical facts presented as text and visuals such as images and videos. The study found that the scores for questions about the benefits and risks of treatment were low, while alternative treatments had high scores. Only one website met the HON code criteria, and a minority of websites achieved JAMA benchmarks. The readability ratings varied across different tests used in the study.

CONCLUSION

Most websites had university or medical center affiliation but only partially related to the specialty. Two-thirds of websites used images. The online information was inaccurate, poor quality, and hard to read for the average person. Dental professionals should be aware of this information's quality and work to improve it.

eHEALS as a predictive factor of digital health information seeking behavior among Brazilian undergraduate students

This study aimed to perform the cross-cultural adaptation and validation of the eHealth Literacy Scale (eHEALS) for Brazilian Portuguese. The cross-cultural adaptation was conducted through conceptual equivalence, verbatim translation, semantic, item and operational equivalence, and back-translation. Subsequently, 521 undergraduate students answered the adapted version of the eHEALS, the General Perceived Self-Efficacy Scale (GSES), the Oral Health Impact Profile-14 (OHIP-14) and sociodemographic and health-related questions. Statistical analysis was performed to determine the dimensionality, internal consistency, stability and concurrent/convergent/discriminant/predictive validities of the eHEALS (p < 0.05). The adequacy of sample size was confirmed by a non-identity correlation matrix (Bartlett's test of sphericity, p < 0.001), without influence of multicollinearity (determinant = 0.026). The confirmatory factor analysis identified four factors in agreement to the constructs namely as online searching self-efficacy, awareness of available sources, information usage ability, and critical analysis of useful information. The eHEALS displayed an excellent internal consistency (Cronbach's alpha = 0.88), a good stability (ICC = 0.71, 95% CI: 0.49-0.84), and it was significantly correlated with GSES (concurrent validity). Higher eHEALS scores were identified among (i) white and (ii) younger students, (iii) from health sciences courses, (iv) with more years of graduation, (v) who their fathers were working in specialized functions (discriminant validity), and (vi) among those who were frequently interested in digital health information (convergent validity). The students with higher eHealth literacy levels were more likely to seek health information in the last 24 h (predictive validity). In conclusion, the eHEALS demonstrated adequate psychometric properties to be applied for the Brazilian population.

Reacting, Sharing, and Commenting: How Many Facebook Users Are Engaging with Posts Related to Dental Caries That Contain Misinformation?

Recent studies have been concerned about the vast amount of misinformation detected on social media that directly hampers the prevention and control of chronic diseases. Based on these facts, the aim of this study was to identify and characterize misinformation about dental caries-related content found on Facebook, regarding the predictive factors of user interaction with posts. Then, CrowdTangle retrieved 2,436 posts published in English, ordered by the total interaction of the highest users. A total of 1,936 posts were selected for inclusion and exclusion criteria to select a sample of 500 posts. Subsequently, two independent investigators characterized the posts by their time of publication, author's profile, motivation, the aim of content, content facticity, and sentiment. The statistical analysis was performed using Mann-Whitney U and χ2 tests and multiple logistic regression models to determine differences and associations between dichotomized characteristics. p values <0.05 were considered significant. In general, posts were predominantly originated from the USA (74.8%), related to business profiles (89%), presented preventive content (58.6%), and noncommercial motivation (91.6%). Furthermore, misinformation was detected in 40.8% of the posts and was positively associated with positive sentiment (OR = 3.43), business profile (OR = 2.22), and treatment of dental caries (OR = 1.60). While the total interaction was only positively associated with misinformation (OR = 1.44), the overperforming score was associated with posts from the business profile (OR = 5.67), older publications (OR = 1.57), and positive sentiment (OR = 0.66). In conclusion, misinformation was the unique predictive factor of increased user interaction with dental caries-related posts on Facebook. However, it did not predict the performance of the diffusion of posts such as business profiles, older publications, and negative/neutral sentiment. Therefore, it is essential to promote the development of specific policies toward good quality information on social media, which includes the production of adequate materials, the increase of the critical sense of consuming health content, and information filtering mediated by digital solutions.

A systematic review of the effectiveness of patient education through patient portals

Objective

The objective of this study was to systematically review all literature studying the effect of patient education on patient engagement through patient portals.

Introduction

Patient portals provide patients access to health records, lab results, medication refills, educational materials, secure messaging, appointment scheduling, and telehealth visits, allowing patients to take a more active role in their health care decisions and management. A debate remains around whether these additional aids actually improve patient engagement and increase their ability to manage their own health conditions. This systematic review looks specifically at the effect of educational materials included in patient portals.

Materials and Methods

In accordance with PRISMA guidelines, the literature search was mapped across 5 databases (PubMed, CINAHL, Scopus, PsychINFO, Embase), and implemented on June 2, 2020.

Results

Fifty-two studies were included in the review. Forty-six (88.5%) reported rates of patient utilization of educational resources in the patient portal. Thirty (57.9%) shared patients' perceptions of the usefulness of the education materials. Twenty-one (40.4%) reported changes in health outcomes following educational interventions through the patient portal. This review found that efforts are indeed being made to raise awareness of educational resources in patient portals, that patients are increasingly utilizing these resources, that patients are finding them useful, and that they are improving health outcomes.

Conclusion

It seems that patient portals are becoming a powerful tool for patient education and engagement, and show promise as a means of achieving the quadruple aim of healthcare. Moving forward, research should establish more uniform methods of measurement in order to strengthen the literature surrounding the effectiveness of patient education through patient portals.

Infodemiology for oral health and disease: A scoping review

INTRODUCTION

Increasing affordability, accessibility and penetration of internet services worldwide, have substantially changed the ways of gathering health-related information. This has led to the origin of concept infodemiology that allows the information to be collected and analysed in near real time. Globally, oral diseases affect nearly 3.5 billion people; thus, volume and profile of oral health searches would help in understanding specific community dental needs and formulation of pertinent oral health strategies.

AIM

To review the published literature on infodemiological aspects of oral health and disease.

METHODOLOGY

This scoping review was conducted in accordance with PRISMA-ScR guidelines. Electronic search engines (Google Scholar) and databases (PubMed, Web of science, Scopus) were searched from 2002 onwards.

RESULTS

Thirty-eight articles were included in this review. The infodemiological studies for oral health and disease were mainly used in two domains. Out of 38 articles, 24 accessed the quality of available online information and 15 studied online oral health-related information seeking behaviour.

CONCLUSION

The most commonly searched oral diseases were toothache, oral cancer, dental caries, periodontal disease, oral maxillofacial surgical procedures and paediatric oral diseases. Most of the studies belonged to developed countries and Google was the most researched search engine.

The use of mind mapping in health education in extended care for children with caries

Objective

To investigate the application of mind mapping-based health education in extended care for children with caries.

Methods

This was a prospective study of 159 eligible children with caries. Participants were randomly assigned to an observation group and a control group, and received extended health education and guidance. Patients in the observation group received health education with mind mapping. In the third month after the first visit, a questionnaire survey was conducted to assess knowledge of extended caries diagnosis and treatment in children and their parents. Children also underwent a bacterial plaque test.

Results

Caries knowledge was significantly greater in the observation group than in the control group. There was no significant between-group difference in debris index on the bacterial plaque test. The observation group had a significantly greater number of follow-up visits in 12 months than the control group.

Conclusions

Mind mapping was effective in the implementation of extended care. Mind mapping information was more accessible to children and their parents, increasing their compliance with health education. Thus, mind mapping is an appropriate health education tool for use in extended care for children with caries.

Web-Based Health Information Following the Renewal of the Cervical Screening Program in Australia: Evaluation of Readability, Understandability, and Credibility

BACKGROUND

Three main changes were implemented in the Australian National Cervical Screening Program (NCSP) in December 2017: an increase in the recommended age to start screening, extended screening intervals, and change from the Papanicolaou (Pap) test to primary human papillomavirus screening (cervical screening test). The internet is a readily accessible source of information to explain the reasons for these changes to the public. It is important that web-based health information about changes to national screening programs is accessible and understandable for the general population.

OBJECTIVE

This study aimed to evaluate Australian web-based resources that provide information about the changes to the cervical screening program.

METHODS

The term cervical screening was searched in 3 search engines. The first 10 relevant results across the first 3 pages of each search engine were selected. Overall, 2 authors independently evaluated each website for readability (Flesch Reading Ease [FRE], Flesch-Kincaid Grade Level, and Simple Measure of Gobbledygook [SMOG] index), quality of information (Patient Education Materials Assessment Tool [PEMAT] for printable materials), credibility (Journal of the American Medical Association [JAMA] benchmark criteria and presence of Health on the Net Foundation code of conduct [HONcode] certification), website design, and usability with 5 simulation questions to assess the relevance of information. A descriptive analysis was conducted for the readability measures, PEMAT, and the JAMA benchmark criteria.

RESULTS

Of the 49 websites identified in the search, 15 were eligible for inclusion. The consumer-focused websites were classed as fairly difficult to read (mean FRE score 51.8, SD 13.3). The highest FRE score (easiest to read) was 70.4 (Cancer Council Australia Cervical Screening Consumer Site), and the lowest FRE score (most difficult to read) was 33.0 (NCSP Clinical Guidelines). A total of 9 consumer-focused websites and 4 health care provider-focused websites met the recommended threshold (sixth to eighth grade; SMOG index) for readability. The mean PEMAT understandability scores were 87.7% (SD 6.0%) for consumer-focused websites and 64.9% (SD 13.8%) for health care provider-focused websites. The mean actionability scores were 58.1% (SD 19.1%) for consumer-focused websites and 36.7% (SD 11.0%) for health care provider-focused websites. Moreover, 9 consumer-focused and 3 health care provider-focused websites scored above 70% for understandability, and 2 consumer-focused websites had an actionability score above 70%. A total of 3 websites met all 4 of the JAMA benchmark criteria, and 2 websites displayed the HONcode.

CONCLUSIONS

It is important for women to have access to information that is at an appropriate reading level to better understand the implications of the changes to the cervical screening program. These findings can help health care providers direct their patients toward websites that provide information on cervical screening that is written at accessible reading levels and has high understandability.

Quality of information about oral cancer in Brazilian Portuguese available on Google, Youtube, and Instagram

Background

To evaluate the quality of oral cancer information in Brazilian Portuguese on Google, YouTube, and Instagram.

Material and Methods

The first 100 links of each platform characterized the initial sample. The websites and Instagram were evaluated using the JAMA benchmarks, the Discern instrument, and the Flesch readability index (Flesch Reading Ease). The existence of Health on the Net (HON) code was also registered on websites. The usefulness of each video on YouTube was classified as not useful, slightly useful, moderately useful, or very useful.

Results

Thirty-four websites, 39 Instagram posts, and 57 videos were evaluated, of which 18 (33.3%) websites and 19 (48.7%) Instagram posts covered only 2 of the 4 JAMA benchmarks. For the Discern instrument, 20 (37%) and 18 (33.3%) websites exhibited low and moderate reliability, respectively, while 26 (66.7%) Instagram posts were of low confidence. The level of intelligibility of both websites and Instagram was difficult. Only three websites exhibited the HONcode. Forty-one (71.9%) videos on YouTube were moderately useful.

Conclusions

Information on oral cancer on the Internet in Brazilian Portuguese is of low quality. Thus, educational and governmental institutions have a responsibility to produce and indicate reliable sources of information for the population.

Key words:Access to information, internet, oral cancer.

Quality of Information Regarding Repair Restorations on Dentist Websites: Systematic Search and Analysis

Background

Repairing instead of replacing partially defective dental restorations represents a minimally invasive treatment concept, and repairs are associated with advantages over complete restoration replacement. To participate in the shared decision-making process when facing partially defective restorations, patients need to be aware of the indications, limitations, and advantages or disadvantages of repairs. Patients are increasingly using the internet to gain health information like this online.

Objective

We aimed to assess the quality of German-speaking dentist websites on repairs of partially defective restorations.

Methods

Three electronic search engines were used to identify German-speaking websites of dental practices mentioning repairs. Regarding information on repairs, websites were assessed for (1) technical and functional aspects, (2) comprehensiveness of information, and (3) generic quality and risk of bias. Domains 1 and 3 were scored using validated tools (LIDA and DISCERN). Comprehensiveness was assessed using a criterion checklist related to evidence, advantages and disadvantages, restorations and defects suitable for repairs, and information regarding technical implementation. Generalized linear modeling was used to assess the impact of practice-specific parameters (practice location, practice setting, dental society membership, and year of examination or license to practice dentistry) on the quality of information. An overall quality score was calculated by averaging the quality scores of all three domains and used as primary outcome parameter. Quality scores of all three domains were also assessed individually and used as secondary outcomes.

Results

Fifty websites were included. The median score of quality of information was 23.2% (interquartile range [IQR] 21.7%-26.2%). Technical and functional aspects (55.2% [IQR 51.7%-58.6%]) showed significantly higher quality than comprehensiveness of information (8.3% [IQR 8.3%-16.7%]) and generic quality and risk of bias (3.6% [IQR 0.0%-7.1%]; P<.001/Wilcoxon). Quality scores were not related to practice-specific parameters (P>.05/generalized linear modeling).

Conclusions

The quality of German-speaking dentist websites on repairs was limited. Despite sufficient technical and functional quality, the provided information was neither comprehensive nor trustworthy. There is great need to improve the quality of information to fully and reliably inform patients, thereby allowing shared decision making.

Is there a relationship of negative oral health beliefs with dental fear and anxiety regarding diverse dental patient groups? A systematic review and meta-analysis

OBJECTIVES

This systematic review and meta-analysis aimed to critically appraise the evidence on the relationship of oral health beliefs with dental fear and anxiety in distinct patient groups.

MATERIALS AND METHODS

Observational studies were retrieved by Cochrane, Embase Search, Portal BVS, Clinical Trials, Ovid, Open Gray, PubMed, Scopus, and Web of Science, and they were manually checked for the inclusion of additional articles of interest. The assessment of quality of studies was performed by the application of three different versions of the Newcastle-Ottawa Scale, for cohort, case-control, and cross-sectional studies. Only studies with low or unclear/moderate risk of bias contributed to meta-analyses, regarding the analysis of random effects of mean differences of dental beliefs scores between dental fear/anxiety and control groups, and the correlation of dental beliefs with dental fear and anxiety measures.

RESULTS

Of 276 articles initially retrieved, 10 were included in the systematic review, while only 6 studies with unclear/moderate risk of bias were considered in meta-analyses. The mean difference of dental beliefs effects was higher in patients with dental fear and anxiety compared to controls (1.20; 95% CI 0.27-2.14; P = 0.01). Additionally, a moderate positive correlation was observed between dental beliefs and dental fear measures (r = 0.54, 95% CI 0.47-0.60;P< 0.001).

CONCLUSIONS

Based on these results, the presence of negative health beliefs is directly related to the increase of dental fear and anxiety; however, these findings are supported in studies with unclear/moderate risk of bias.

CLINICAL RELEVANCE

Dental fear and anxiety is an important obstacle for the access of dental treatment and patient-dentist relationship, leading to inadequate oral health levels.

Digital behavior surveillance: Monitoring dental caries and toothache interests of Google users from developing countries

OBJECTIVE

To determine the differences between the levels of interest of South American Google users on information related to dental caries and toothache over time.

MATERIALS AND METHODS

The monthly variation of Relative Search Volume (RSV) for both queries was obtained in Google Trends between 2004 and 2017. The association between RSVs, Internet penetration, and disability-adjusted life-years (DALYs) for dental caries in permanent teeth were tested by distinct regression models. Forecasting ARIMA models were developed to analyze trends and predict the interests until December 2018.

RESULTS

In general, toothache-related searches presented an uptrend associated positively with Internet penetration and negatively with DALYs, whereas dental caries-related searches presented a downtrend associated negatively with Internet penetration and positively with DALYs. The seasonality affected only dental caries curves, with the highest rates observed in the first trimester and the lowest rates in June, July, and December.

CONCLUSION

The levels of interests of South American Google users in seeking dental caries and toothache information appear to have a direct connection with the burden of untreated dental caries lesions and Internet penetration. The no association between dental caries- and toothache-related interests reinforces the unfamiliarity of most people about the relationship of dental pain with the final stages of chronic oral diseases.
