AIM: The aim of this study was to examine various storage environments for storing fragments before being bonded to the remaining teeth. MATERIALS AND METHODS: Forty maxillary incisor teeth were fractured on the incisal one–third and were divided into four groups of 10 each to be stored in normal saline, milk, coconut water and dry environments for 24 hours. All the fractured parts in each group were bonded to their relevant apical parts by an etch and rinse bonding system and a flowable composite resin. The fracture resistance was measured by a universal testing machine, and the results were analyzed using one–way ANOVA and Tukey statistical tests. RESULTS: The results revealed that the difference among the four groups was statistically significant (P=0.000). Tukey tests showed that the force required for fracturing fragments kept in the milk environments were significantly higher than those for the normal saline, coconut water and dry environments (P>0.05 ). CONCLUSIONS: It was concluded that keeping the fractured parts in milk storage environment can increase the required force for fracturing teeth more than the other environments.
