Abstract
INTRODUCTION: Gingival melanosis is characterized by a change in the physiological color of the gingiva, that usually ranges from brown to black. It can be a source of discomfort for affected people, an attractive gingiva being associated with a pink color. The main objective of this study was to compare knowledge about gingival melanosis between fourth- and fifth-year dental students and dental professors at the European University of Valencia. METHODS: The conduct of this cross-sectional observational study was approved by the Research Ethics Committee of the European University of Valencia. The survey used was drafted by the authors of the study. Participants completed the questionnaire between February and March 2024. Statistical analysis was performed using IBM SPSS 23.0. RESULTS: Significant differences were found between the knowledge of both groups regarding monthly and annual detection frequency (p < 0.001), diagnostic with the DOPI index (p = 0.048), treatment options (p < 0.001), recurrence (p = 0.004) and impact on the patient's life (p = 0.012). Professional knowledge was higher, except regarding the impact. Conversely, there were no significant differences in the detection of gingival melanosis, etiologies, the ways to transmit information to the patient and diagnosis using the melanin and gingival pigmentation indices. CONCLUSIONS: It can be concluded that teachers' knowledge is more important in terms of detection frequency, use of the DOPI index, treatment options and recurrence, except for the impact on the patient's life. However, in terms of detecting gingival melanosis in the oral cavity, possible etiologies and diagnostic methods such as the melanin and gingival pigmentation index, knowledge is the same between both groups.
