Evaluation of buccal enamel of deciduous incisors stored in three different solutions with Diagnodent laser fluorescence

摘要

This study evaluated the influence of different storage solutions on teeth from a tooth bank, using DIAGNOdent laser fluorescence at 3 time periods. The storage solutions used in the study were: refrigerated water, saline, and 10% formol. Eighteen visually intact deciduous incisors were divided into three groups of six samples each. The teeth were previously cleaned, dehydrated and measured using DIAGNOdent at the most prominent buccal region of each tooth. Three subsequent measurements were taken at 1, 7 and 15 days. All measurements were taken by the same examiner and averages were recorded for each time period. Results showed that the three solutions had similar responses to laser. ANOVA was applied to verify the correlation between measurements, time periods, and storage solutions. Statistically significant differences were found only between the time periods. In this in vitro study, all three storage solutions influenced the DIAGNOdent measurement results as time elapsed until the 24 h period.
