Children are the most common victims of anterior teeth trauma. An alternative treatment choice to composite treatment in uncomplicated crown fracture is fragment reattachment, when the fragment is retrieved and reusable. It is a conservative and minimally invasive approach. Storage of fragment plays a key role in improving strength of the reattachment. But only limited data is available on evaluation of storage media as a parameter in improving strength of fragment reattachment. Hence the present study was designed. Material and Method: 48 extracted human central incisors were divided into 4 groups: group I milk, group II normal saline, group III tender coconut water and group IV dry (n=12). Teeth were sectioned at the junction of incisal and middle third with double sided diamond disc. Fragments were stored in respective storage media. After 24 hours of storage fragments were reattached by simple reattachment technique using same etchant and same bonding agent in all the groups. Reattached teeth were stored in distilled water and subjected to thermo cycling. Fracture strength testing was done using universal testing machine. Data was tabulated and subjected to statistical analysis. Results: Group III demonstrated highest fracture resistance followed by group I and group II. Group IV achieved least fracture resistance. Conclusion: Newly tested tender coconut water can be used as a storage medium for fragment reattachment based on its ability to increase fracture resistance.
