Telediagnosis of oral lesions using smartphone photography

Technological aspects and recommendations for applying teledentistry in oral medicine: a scoping review

BACKGROUND

Teledentistry is applied in oral medicine to help dental practitioners and specialists manage complex oral conditions. This scoping review aims to synthesize the available evidence regarding the technical requirements and the provision of security services, as well as the recommendations on standard oral cavity photography methods for using teledentistry in oral medicine.

METHOD

The present scoping review was conducted in 2022 according to the Joanna Briggs Institute (JBI) manual. Four databases were systematically searched, including ISI Web of Science, PubMed, Scopus, and ProQuest, from January 1999 to December 2021. After finalizing the search strategy, all the original articles, reviews, editorials, letters, comments, and book chapters were included. All the dissertations uploaded in English with a full-text electronic file were also included to achieve a comprehensive picture of the available literature. Two types of analysis were applied: the quantitative descriptive analysis applying Excel 2016 and the qualitative thematic analysis using MAXQDA version 10.

RESULTS

The included papers were published during 1999-2021. Most of the included articles were from Brazil (n = 9, 21.43%), India (n = 6, 14.28%), the USA (n = 6, 14.28%), and the UK (n = 5, 11.90%). Social media usage as a teledentistry platform increased considerably between 2019 and 2021. Teledentistry platforms have been classified into four categories, including email, telephone, social network applications (WhatsApp, zoom, Google Meeting, Instagram, line Application, Viber, and Messenger), and teledentistry systems (teledentistry systems, which were designed specially to perform a teledentistry project). Teledentistry has been conducted to store and forward (n = 15, 30.71%), real-time (n = 9, 21.43%), or both (n = 12, 35.71%). According to the thematic results, basic technical requirements have been categorized into four, including teledentistry platform, type of interactions, internet connection, and photography tool. Other thematic results demonstrate seven categories of recommendations, including general factors, light, patient position, phone position, setting of a mobile phone camera, photo sending requirements, and photo visualization.

CONCLUSION

According to the results, over the past 7 years, especially during the COVID-19 pandemic, social network applications such as WhatsApp and Zoom have been used more frequently. Also, photography recommendations with a mobile phone camera depend on several factors such as general factors, light, patient position, phone position, setting of the mobile phone camera, and photo-sending requirements. Given the increased use of mobile cameras for oral photography, these recommendations can help improve the quality of images and subsequently improve the reliability of clinical decision-making in managing patients' conditions.

Inclusion of clinical photographs with general dental practitioner electronic referrals of patients with oral mucosal disease to secondary care: a service review

Introduction This service evaluation reviewed how the inclusion of photographs in dentist referrals to an oral medicine specialist service can improve the service for triage, prioritisation and diagnosis.Materials and methods Data were prospectively collected from e-referrals over a four-month period. Any change in appointment prioritisation resulting from review of photographs at the vetting stage was recorded.Results Only 29.5% (82 of 367) of referrals included a photograph. Of these, 5% were 'rejected with advice' since the photograph indicated the patient did not require a secondary care appointment. Additionally, 14% of all referrals were upgraded in urgency, five of which were due to concerns of malignancy, and three of five were upgraded solely based on the photographs as they showed features of possible malignancy, where the written element of the referral did not describe nor raise such concerns.Discussion and conclusions Including a photograph with a referral can often make up for inaccurate or insufficient written content, allowing appropriate and safe prioritisation, especially where the referrer has failed to recognise possible malignancy. Photographs can also prevent unnecessary referral upgrades, ensure an appointment is necessary and can be invaluable as a baseline comparator.

Use of digital strategies in the diagnosis of oral squamous cell carcinoma: a scoping review

Telediagnosis uses information and communication technologies to support diagnosis, shortening geographical distances. It helps make decisions about various oral lesions. The objective of this scoping review was to map the existing literature on digital strategies to assist in the diagnosis of oral squamous cell carcinoma. this review was structured based on the 5-stage methodology proposed by Arksey and O'Malley, the Joanna Briggs Institute Manual for Evidence Synthesis and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. The methods were registered on the Open Science Framework. The research question was: What digital strategies have been used to assist in the diagnosis of oral squamous cell carcinoma? The search was conducted on PubMed/MEDLINE, Scopus, Web of Science, Embase, and ScienceDirect. Inclusion criteria comprised studies on telediagnosis, teleconsultation or teleconsultation mediated by a professional and studies in English, without date restrictions. The search conducted in June 2023 yielded 1,798 articles, from which 16 studies were included. Telediagnosis was reported in nine studies, involving data screening through applications, clinical images from digital cameras, mobile phones or artificial intelligence. Histopathological images were reported in four studies. Both, telediagnosis and teleconsultation, were mentioned in seven studies, utilizing images and information submission services to platforms, WhatsApp or applications. One study presented teleconsultations involving slides and another study introduced teleconsultation mediated by a professional. Digital strategies telediagnosis and teleconsultations enable the histopathological diagnosis of oral cancer through clinical or histopathological images. The higher the observed diagnostic agreement, the better the performance of the strategy.

Tele-dentistry, its trends, scope, and future framework in oral medicine; a scoping review during January 1999 to December 2021

BACKGROUND

Tele-dentistry has been increasingly used for different purposes of visit, consultation, triage, screening, and training in oral medicine. This study aims to determine the main facilitators, barriers, and participants` viewpoints of applying tele-dentistry in oral medicine and develop a framework indicating the input, process, output, and feedback.

METHOD

This was a scoping review conducted in 2022 applying Arksey and O'Malley (2005) approach. Four databases including ISI web of science, PubMed, Scopus, and ProQuest were searched from January 1999 to December 2021. Inclusion criteria consisted of all original and non-original articles (reviews, editorials, letters, comments, and book chapters), and dissertations in English with a full text electronic file. Excel₂₀₁₆ was used for descriptive quantitative analysis and MAXQDA version 10 was applied for qualitative thematic analysis. A thematic framework was developed customizing the results of the review in a virtual mini expert panel.

RESULTS

Descriptive results show that among 59 included articles, 27 (46%) have addressed the various applications of tele-dentistry during COVID-19 pandemic in the field of oral medicine. From geographical distribution perspective, most of the papers were published in Brazil (n = 13)/ 22.03%, India (n = 7)/11.86% and USA (n = 6)/10.17%. Thematic analysis shows that seven main themes of "information", "skill", "human resource", 'technical", "administrative', 'financial', and 'training and education' are explored as facilitators. 'Individual', 'environmental', 'organizational', 'regulation', 'clinical', and 'technical barriers' are also identified as main barriers of tele-dentistry in oral medicine.

CONCLUSION

According to the results for using tele-dentistry services in oral medicine, a diverse category of facilitators should be considered and at the same time, different barriers should be managed. Users` satisfaction and perceived usefulness of tele-dentistry as final outcomes can be increased considering the system`s feedback and applying facilitator incentives as well as decreasing the barriers.

Factors important in the correct evaluation of oral high-risk lesions during the telehealth era

BACKGROUND

Considering that early detection of squamous cell carcinoma (SCC) improves prognosis and clinical examination is the primary detection method, we identified factors related to the clinical evaluation of oral mucosal lesions. Due to the growing role of telehealth, our study was based on clinical image evaluation.

SUBJECTS AND METHODS

Oral medicine specialists and dental students evaluated six images of benign, potentially malignant, or SCC lesions (18 images in total). We analyzed the role of personal factors of the examiners and the visual pathological features of the lesion upon which the participants based their evaluation.

RESULTS

One hundred thirty-three subjects participated. Half of the benign images were correctly evaluated. On average 1.2 (±SD1.3) cancer pictures were recognized correctly and 3.66 (±SD1.42) images were considered potentially malignant. Potentially malignant lesions were correctly evaluated at an average of 4.08 (±SD1.48) images. For cancer and potentially malignant lesion images, there were significantly better results among clinicians with the worst results from the fourth-year students. Student results correlated significantly with years of study, number of weeks spent in the oral medicine clinic, and interest in oral pathology. Consideration of lesion irregularity yielded a correct diagnosis, whereas wrong answers were based on color changes. Lesion size and margins were considered equally important.

CONCLUSIONS

Using clinical images as part of the diagnostic process provides good results, though increased clinical experience for graduates and undergraduates may be necessary to improve accuracy. Therefore, emphasizing the important visual parameters of malignancy may be valuable in the current telehealth era.

Use of smartphone photos to document the oral care status of nursing home residents

OBJECTIVE

Investigate whether clinically assessed oral care status by an external dentist can be replicated using smartphone photographs.

BACKGROUND

Many people with care needs have poor oral hygiene. To help maintain oral health, caregivers require a simple way of communicating oral care status to the dental team.

MATERIALS AND METHODS

Cross-sectional study in which smartphone photographs of the oral and prosthetic care situation of N = 50 nursing-home patients (mean age 85.6 [SD 6] years, 74% women) were assessed by two blinded, external examiners (D1/D2) and compared with clinical assessments made by the onsite dentist who also took the photographs (D0). Intraoral care status was clinically evaluated using the modified Plaque Index for Long-Term Care (PI-LTC) and Denture Hygiene Index (DHI). The intraclass correlation coefficient (ICC) determined correlations between clinical and photographic findings.

RESULTS

The ICC was assessed for the PI-LTC (upper jaw, n = 41; lower jaw, n = 49) and DHI (upper jaw, n = 25; lower jaw, n = 18). The DHI showed excellent reliability between clinical assessment and smartphone evaluation for the determination of positive surfaces (ICC: upper 0.91 [95% confidence interval (CI) 0.83-0.96], P < 0.001; lower 0.95 [95% CI 0.89-0.98], P < 0.001). The PI-LTC showed good reliability between clinical assessment (D0) and D1/D2 for determination of vestibular plaque (ICC: upper 0.84 [95% CI 0.74-0.91], P < 0.001; lower 0.87 [95% CI 0.79-0.92], P < 0.001).

CONCLUSIONS

Although limited, this pilot study demonstrated that standardised smartphone photographs can simply communicate the intraoral care status of patients who have difficulties accessing their dentist. This should be considered when planning improved communication between dentists, care recipients, and their support network.

Dentistry website analysis: An overview of the content of formulated questions and answers

Aim

This study aimed to analyze the content of questions and answers posted on dentistry websites.

Subject and methods

A mixed-method study was conducted in 2020. A total of 1354 related questions were included, of which 1182 were answered by dentists. The data was analyzed quantitatively according to the classification of the questions, main complaints of the subjects and length of the questions and answers using Excel₂₀₁₃. A qualitative content analysis was carried out also for data robustness and triangulation.

Results

Of the 1354 questions, 866 of them were categorized into 11 categories according to the main sub-classes of the International Classification of Diseases to Dentistry and Stomatology. Furthermore, the inquiries were allocated to 3 communication styles to present the users' main complaints that included contextual (52.33%), emotional (6.79%) and focal (40.89%) strategies. Results of the qualitative content analysis have led to 6 main themes: seeking the related recommendations of any actions, treatment seeking, information seeking, seeking for causes and reasons, seeking for oral and dental health recommendations and seeking for the dentists' diagnosis or comments.

Conclusions

The present study can be used for designing specific customized websites of dentistry and help the website managers for better optimization of the websites. All these interventions can pave the way for developing teleconsulting in dentistry for middle-income countries.
