Without a doubt you still need sectioning to measure bone deposition by tetracycline fluorescence.  Bone is only 10-30% tissue and at least 70% hydroxyapatite, a mineral that does not transmit light.  This property has given my current research group, which very much would like to see bone cells in their natural environment, more than a little bit of grief.
