Introduction: It is still not clear if enamel defects have any esthetic implication, especially when anterior teeth are affected. Purpose: The aim of this study was to evaluate how fluorosis has been perceived by teenagers and dental health professionals of different specialties and what kind of treatment those professionals are proposing. Methods: The sample consisted of 69 teenagers aged from 10 to 14-years that answered the following questions: “Are you satisfied with the appearance of your teeth?”; “Do you perceive any different aspects on your teeth?” “If so, what do you perceive?”. The fluorosis diagnostic of upper front teeth was carried out by two epidemiologists through the analysis of the photographs of volunteers´ teeth. The results from the epidemiologist were selected and showed the least intra-examiner error. The following questions about diagnostic and treatment attached to the photographs were answered by dentists from government services and specialists of Restorative dentistry and Pediatric dentistry: “Are there any visible alterations in the enamel of one or more teeth in the photograph?”; “What should your procedure be for the diagnostic found?”.Hypothesis testing was carried out using chi-squared test for proportions at a significance level at P=0.05. Results: Fluorosis was perceived by 13.1% of the teenagers. The percentage of fluorosis diagnosed by the specialists and dentists from government services was 25.4% and 27.7%, respectively (P>0.05). Conclusions: The dental health professionals perceive more fluorosis than adolescents, and indicate invasive treatment for this condition.
