Experiences, perceptions, and decision-making capacity towards oral biopsy among dental students and dentists.

The dentist plays a crucial role in identifying oral lesions as it is their responsibility to conduct the clinical examination for diagnosing diseases in this anatomical region. Dentists should be able to perform simple oral biopsies when this procedure is necessary. However, several studies point out that dentists lack experience and perceive themselves incapable of performing biopsies. This analytical cross-sectional study aimed to assess participants' experiences and perceptions regarding a continuing education activity focused on the biopsy procedure. The secondary aim was to evaluate their ability to determine when a biopsy is indicated. The sample consisted of 228 individuals: 143 dentists and 85 undergraduate dental students who completed questionnaires related to a lecture held in May/2021, as part of the continuing educational activities of the "Red May" Project. Participants completed two questionnaires: the first assessed their experience and self-confidence in performing oral biopsies, whereas the second evaluated their capacity to define when the biopsy is indicated by means the evaluation of 10 clinical cases. The results reveal no significant difference in the percentage of correct answers between dental students and dentists. Regarding the frequency of performing the biopsy procedure, most respondents (69.7%) reported doing so rarely or never. Furthermore, while 31.6% of the participants stated that they perform biopsies depending on the case, 68.4% prefer to refer patients to specialists, such as professionals in Stomatology/Oral Medicine. These findings highlight limitations in the educational preparation of the study population concerning biopsy procedures, oral lesions, and their management. They also indicate a concerning tendency to overestimate knowledge in this area. Thus, this study emphasizes the importance of continuing education and underscores the need to revise academic curricula and provide complementary education for all dental professionals.

EstomatoNet: A 5-year experience of an oral medicine telediagnosis service.

OBJECTIVE: EstomatoNet is an online service driven by primary health care professionals to support diagnosis and decision-making for oral lesions. This study aimed to describe the experience of the service, depicting use cases and its impact on the referral to specialised services. MATERIALS AND METHODS: Patient/applicant demographics and information related to their oral lesions and/or complaints were retrieved from the service's cloud-based platform. The differential diagnosis provided by the applicants, their level of satisfaction and the teleconsultant's opinion in terms of diagnosis and management were also reported. The teleconsultant's suggestion was cross-referenced with the data from the regulation system to verify the avoidance of referral. RESULTS: Out of 2,002 teleconsultations, most patients were women (55.1%) and 50.1% were aged between 20 and 59 years. Applicants (96.5%) generally considered the service very satisfying/satisfying. Potentially malignant disorders were reported in 19.6% of cases and 7.7% were suspected to be malignant. The referral of 37.3% of patients was avoided after the suggestion of keeping the patient in the primary health care system (k = 0.234; p < 0.001; 62.2% agreement). CONCLUSION: The use of EstomatoNet for oral mucosal lesions improves support for primary health care professionals in the management of lesions and reduces referral to specialised services.

Effectiveness of phytotherapeutics in the prevention and treatment of 5-fluorouracil-induced oral mucositis in animal models: A systematic review.

OBJECTIVES: This systematic review evaluated the effect of phytotherapeutics in the treatment and prevention of 5-fluorouracil (5-FU)-induced oral mucositis (OM) in animal models. DESIGN: A search was performed in PubMed/Medline, CENTRAL (The Cochrane Library), EMBASE, and Web of Science, including studies published up to January 2020. Only articles investigating the chemoinduction of OM by 5-FU in animal models were included. Eligibility was evaluated and data were extracted from the eligible studies following the predefined PICO questions. The Cochrane Collaboration Risk of Bias Assessment tool was used to evaluate the quality of the included studies. RESULT: A total of 503 articles were retrieved and 13 were included. The hamster was the animal model used in all included studies. The treatment method ranged from the topical application of ointment (n = 3), gel (n = 5) and extract (n = 3) to the oral ingestion of the phytotherapeutics (n = 3). Chamomilla recutita L. (n = 3) and Pistacia atlantica (n = 3) were the most used therapeutic agents. Although all studies were classified as high risk of bias, all of them reported promising results regarding the use of phytotherapeutics in the management of OM, including lower clinical and histopathological scores as well as healing, anti-inflammatory, antimicrobial, and antioxidant activities. CONCLUSION: Despite the high risk of bias of the studies, phytotherapy is a promising alternative for the treatment of 5-FU-induced OM, showing interesting results in terms of tissue healing and anti-inflammatory, antimicrobial and antioxidant activity.

Perceived usability of a store and forward telehealth platform for diagnosis and management of oral mucosal lesions: A cross-sectional study.

EstomatoNet was created in the south of Brazil to provides specialist support over a web-based platform to primary care dentists for diagnosis of oral lesions. To evaluate the usability of EstomatoNet and to identify user perceptions regarding their expectations and difficulties with the system; and to compare the perceptions of regular users of the service to those of first-time users. Sixteen dentists were selected for the study: 8 were frequent users of EstomatoNet and 8 were residents who had never used the Platform. To assess usability, participants were required to request telediagnosis support for a fictional case provided by the research team. During the process of uploading the information and sending the request, users were asked to "think out loud," expressing their perceptions. The session was observed by an examiner with remote access to the user's screen (via Skype). After the simulation, users completed the System Usability Scale (SyUS), a validated tool with scores ranging from 0 to 100. The mean SyUS score assigned by frequent users was 84.7±6.6, vs. 82.2±9.3 for residents (satisfactory usability: score above 68). The difference between the groups was not statistically significant (Student t test, P = .55). The residents group took longer (347.1±101.1s) to complete the task than frequent users (252.8±80.3s); however, the difference between the groups was not statistically significant (Student t test, P = .06). In their subjective evaluation, users suggested the inclusion of a field to add further information on outcomes and resolution of the case and changes in the position of the "Send" button to improve workflow. The present results indicate satisfactory usability of EstomatoNet. The Platform seems to meet the needs of users regardless of how experienced they are; nevertheless, a few minor changes in some steps would improve the tool.

Cowden syndrome--a case report emphasizing the role of the dental surgeon in diagnosis.

Cowden syndrome or multiple hamartoma syndrome, is a rare genetic condition inherited in an autosomal dominant pattern characterized by cutaneous manifestations, polyps, thyroid gland neoplasias, and macrocephaly. This report presents the case of a 36-year-old patient who looked for dental treatment for a gingival nodule. Current and past medical history and oral and facial manifestations led to the diagnosis of Cowden syndrome. This case report emphasizes the role of the dental surgeon in the diagnosis of this systemic disease, based on the analysis of medical history and manifestations in the oral cavity.
