Could Teledentistry Be a Solution in the Diagnosis of Oral Lesions?

In recent years, teledentistry has gained visibility, especially because of the COVID-19 pandemic. Concerning oral medicine, there is great expectation, particularly about its potential to promote early diagnosis of oral lesions. In southern Brazil, two initiatives have shown a positive influence on each other and have led to greater awareness of oral cancer and more access to qualified advice on diagnosing and managing oral lesions.

Substance use and its association with mental health among Swiss medical students: A cross-sectional study.

Background: Studies on mental health and substance use among medical students indicated worrying prevalence but have been mainly descriptive.

Aim: To evaluate the prevalence of substance use in a sample of medical students and investigate whether mental health variables have an influence on substance use.

Methods: The data were collected as part of the first wave of the ETMED-L, an ongoing longitudinal open cohort study surveying medical students at the University of Lausanne (Switzerland).

Convolutional neural network misclassification analysis in oral lesions: an error evaluation criterion by image characteristics.

Objective: This retrospective study analyzed the errors generated by a convolutional neural network (CNN) when performing automated classification of oral lesions according to their clinical characteristics, seeking to identify patterns in systemic errors in the intermediate layers of the CNN.

Study Design: A cross-sectional analysis nested in a previous trial in which automated classification by a CNN model of elementary lesions from clinical images of oral lesions was performed. The resulting CNN classification errors formed the dataset for this study.

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.

Contribution of public oral pathology services to the diagnosis of oral and oropharyngeal cancer in Brazil.
