RESUMO
Tooth sensitivity is a common clinical problem. This multi-center randomized clinical trial assessed the effectiveness and safety of topical diammine silver fluoride. From two sites (Lima and Cusco, Peru), 126 adults with at least one tooth sensitive to compressed air were randomly assigned to either the experimental treatment or sterile water, and pain was assessed by means of a 100-mm visual analogue scale at 24 hours and 7 days. The diammine silver fluoride reduced pain at 7 days at both sites. At the Lima site, the average change in pain scores between baseline and day 7 for the silver fluoride group was -35.8 (SD = 27.7) mm vs. 0.4 (SD = 16.2) mm for the control group (P < 0.001). In Cusco, the average change in pain scores for the silver fluoride group was -23.4 (SD = 21.0) mm and -5.5 (18.1) mm for the control group (P = 0.002). No tissue ulceration, white changes, or argyria was observed. A small number of participants in the silver fluoride group experienced a mild but transient increase in erythema in the gingiva near the tooth. No changes were observed in the Gingival Index. We concluded that diammine silver fluoride is a clinically effective and safe tooth desensitizer.

The Dental Fear Survey (DFS), a paper and pencil instrument for assessing dental fear and avoidance, has been widely used and validated in fear studies in the US. However, before such instruments are used in countries and cultures dissimilar to the one in which it was developed, they should be cross-validated in that culture. The present study is an examination of the DFS response characteristics in a group of 374 Brazilian university students. Factor analysis of the DFS revealed three factors essentially identical to those found among university students in the US and in Singapore, as well as among US adult dental patients. Higher DFS scores were significantly associated longer intervals since last dental visit. These results are taken as evidence that the DFS performs in this Brazilian sample very much as it does in other samples; and is thus, a valid indicator of dental fear at least among Brazilian university students.
