Stress, relaxation, and saliva: a pilot study involving endodontic patients.

Thirty-four endodontic patients completed dental anxiety questionnaires and had saliva samples taken prior to and at the conclusion of their initial endodontic treatment. Pain and anxiety were managed with local anesthesia, nitrous oxide--oxygen psychosedation, hypnosis, and meditation, either alone or in combination. For most patients, by the conclusion of the treatment, anxiety had decreased, salivary volume had increased, and salivary protein was reduced. Meditation and hypnosis, either alone or in combination with local anesthesia, were most effective in anxiety reduction as measured by questionnaire and/or salivary changes.
