title: Natural desensitization of exposed tooth roots in dogs.
abstract: With scanning electron microscopy, electron microprobe elemental analysis, and an objective method for eliciting responses to electrical stimuli, exposed tooth root surfaces in dogs were found to become naturally desensitized with time, perhaps because of the formation of acquired pellicle.
