unwanted deleted rows from database

[AtkinElw]

Hi,

I deleted by accident 28 row from SQL server 2005 database (via SQL Management Studio Express) from table ParameterDefinition with columns (Id, Name, PluginId, Description, DefaultValue).
My command was: delete from ParameterDefinition where Name = 'RateOfVat'.
I only wanted to delete one row but I haven't realized that there are more such rows.

Do you know how to repair it to original state or how to find out (from logs) what was deleted? thanks

Restore from backup?
Is the database setup with recovery model as "FULL"?
Is that from some app?
