ConclusionConclusionThe excretion capacity (S%) is reduced three months after TBI/BMT in both parotid and submandibular glands.
The capacity to recover function is obvious in the submandibular glands, but is hardly present in the parotid glands one year after TBI/BMT.
A reduced recovering capacity of the parotid glands is a contributing factor to the reduced whole salivary secretion rate seen one year after TBI/BMT.
