Purpose: to analyze synchronous teleconsultation as a support tool in the management of temporomandibular disorders in primary health care and to identify which factors have an impact on decisions about teleconsultation. Methods: retrospective study perfomed in TelessaúdeRS, between May 2018 to May 2020. This study used primary data from synchronous teleconsultation, requested by primary health care professionals and carried out by multiprofessional teleconsultants. The data collected were the information reported by the requester, the teleconsultant's suggestions and if there was referral of the patient for specialized care after teleconsultation. The statistical association was investigated between patient characteristics and decision of teleconsultation; and teleconsultation conduct suggestions and decision of teleconsultation, using Fisher's exact test and modeling was performed using binary logistic regression considering 5% of significance (p≤0.05). Results: during the period, 56 teleconsultations had a temporomandibular diagnostic hypothesis, these 79.2% patients were female and the average age was 43.7 years. In 59.1% of teleconsultations, primary care management was suggested, with 72.4% of patients being managed. An association was found between the decision of teleconsultation and referral to specialized care (p <000.1). The trauma report (p = 0.004) was associated with a greater chance of being referred for special care and suggestions for pharmacological (p <0.001) and non-pharmacological (p = 0.007) treatments were introduced among the teleconsultation managed in primary care. Conclusion: teleconsultation helped to manage the majority of temporomandibular disorder, streamlining care and having the potential to avoid unnecessary referrals to special care.

EstomatoNet was created in the south of Brazil to provides specialist support over a webbased 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.
