ABSTRACT Background & objectives: Dental trauma is one of the most prevalent traumatic injuries of face especially in young patients.Children are mostly the victims at school going age wherethe permanent tooth crown fracture is more common. Fragment reattachment to the teeth has several advantages as it restores the esthetics and natural teeth form with a minimal tooth preparation. Even though there are several methods of fractured fragment reattachment maintaining the fragment in wet environment before reattachment has proven to provide better results. Rehydrated teeth fragment in particular storage media retains the dentin moisture and aids in high bond strength during the use of dental adhesives. The objective of this study is to evaluate the bond strength of the reattached fractured fragment when stored for 24 hours in Milk,Aloevera gel, tender coconut water and at dry environment, and to compare the bond strength of the reattached fractured fragment when stored in various storage media to evaluate the better storage media. Materials and methods: 60 maxillary central incisors were randomly divided into four groups containing 15 teeth each. Four groups are: � Group A: Milk � Group B: Aloe Vera Gel � Group C: Tender Coconut Water � Group D: Dry After tracing a line on each teeth 3 mm from the incisal edge a diamond disk was used to cut the teeth. All the fragments were stored in the respected storage media for 24 hours (All the storage media was changed every 6 hours). Ice trays labeled with the storage media was used. Both the fractured segments are etched with 37% phosphoric acid for 15 seconds. Then bonding agent is applied on both the etched surfaces and cured. The fragments were held with the help of gutta percha stick and are approximated using Ivoclar composite and cured. Reattached samples were kept in distilled water and they were mounted on PVC tubes with the help of cold cure resin. The samples were kept loaded on the universal strengthtesting machine using a locking vice and a compressive load was applied on the incisal third of the teeth at 90 degrees.The bond strength of each specimen was tested and measured in kilo newton. Results: The results of the present study suggest that milk is the better storage media when compared to other storage medias used in this study. Moreover milk has significant result when compared to Aloevera gel and Tender coconut water. The results were not significant when Aloe gel, Tender coconut water and dry environments are compared individually, although Aloe vera gel showed better results it was not statistically significant. Conclusion: Milk which is considered as a gold standard storage media has given best bond strength for fragment reattachment, although not proven by many clinical studies Aloeveragel which has many nutrients can also be used as a storage media to store a fractured fragment.
