- Abstract:
- The purpose of this study was to compare different solutions for the storage of teeth and their influence on the enamel surface. The bond strength of bonded brackets on the enamel surface was determined by shear testing with an Instron measuring machine (feed rate 0.5 mm/min). Previously, these teeth had been stored in different solutions and their bond strengths were compared to the values of freshly extracted teeth. The statistical depiction was performed by means of descriptive and explorative data analysis. The analysis was carried out with the SPSS program. For group comparison purposes, the single-factor variance analysis (ANOVA) and the Post Hoc Test (Tukey HSD) were used. The level of significance was set at P < .05. The study showed that bond strength using formaldehyde fixation came closest to bond strength from freshly extracted teeth, so a formaldehyde solution should be used for storage. Only bond strength with teeth stored in thymol was significantly different (P = .02) from that observed with freshly extracted teeth.
