Evaluation of the diagnostic ability of oral lesions on clinical images among undergraduate dental students.

INTRODUCTION: The dentist should be able to carry out systematic oral examinations of the mucosa of patients in order to diagnose any alterations at an early stage. MATERIALS AND METHODS: An observational, analytical, prospective, and longitudinal study was carried out. 161 students were evaluated at the beginning of their clinical practice in their 4th year of dental school (September 2019), at the beginning and at the end of their 5th year of dental school (June 2021). Thirty oral lesions were projected, and the students were asked to provide an answer; if the lesions were benign, malignant, or potentially malignant, whether they should be biopsied and/or treated and a presumptive diagnosis. RESULTS: Significant improvement (p < .001) was obtained between the 2019 and 2021 results, in relation to the classification, need for biopsy and treatment of lesions. For differential diagnosis, no significant difference (p = .985) was obtained between the 2019 and 2021 responses. Malignant lesions and PMD obtained mixed results, with the best results corresponding to OSCC. DISCUSSION: In this study, a correct lesion classification by the students was over 50%. As for the OSCC, the results were superior to the rest of the images, reaching more than 95% correct. CONCLUSION: Theoretical-practical training from universities and continuing education for graduates in relation to oral mucosal pathologies should be further promoted.

Colutorios para el tratamiento de la halitosis intraoral: actualización y puesta al día / Review and update: mouthwashes for the treatment of intraoral halitosis

Antecedentes: En la sociedad actual, la halitosis es motivo de preocupación creciente de los pacientes, los cuales demandan a sus profesionales soluciones terapéuticas para el tratamiento de esta entidad de etiología multifactorial. Los compuestos sulfurados volátiles, originados, fundamentalmente, por las bacterias anaerobias gram negativas e la microbiota oral, son los principales responsables de mal olor oraObjetivo: Realizar una revisión yactualización de la evidencia científica respecto a los principales componentes activos de los enjuagues orales empleados para el tratamiento de la halitosis intraoral Material y método: Se realizó una búsqueda bibliográfica en las bases de datos: Medline/PubMed, Cochrane Library, Scopus y Web of Science empleando los términos de búsqueda: Halitosis AND mouthwash OR mouthrinse hasta Julio del 2021.Conclusión: La eficacia de los colutorios para el tratamiento de la halitosis dependerá del tipo de principio activo, o la combinación de ellos, de la formulación, así como, de la realización de un correcto diagnóstico etiológico (AU)
