Intracanal use of a corticosteroid solution as an endodontic anodyne.

In fifty consecutive clinical patients with endodontically involved teeth that responded with vital pulp test readings, a corticosteroid solution and a saline placebo were alternately used as an intracanal anodyne. The patients subjectively rated their pain on a scale of 0 to 100 as "none," "mild," "moderate," and "severe" (0 = none, 1 to 33 = mild, 34 to 66 = moderate, 67 and above = severe). The ratings were done before the first treatment and then at 24, 48, and 72 hours after treatment. Corticosteroid-treated and placebo-treated cases were not significantly different in terms of type of teeth treated, clinical pulpal diagnosis, and preoperative patient evaluation of pain. The results showed a decreased subjective report of pain for the corticosteroid cases as compared to the controls through the three posttreatment time periods (p less than 0.10). A statistically significant decreased incidence of pain was reported for the corticosteroid cases as compared to the control at the 24-hour time period (p less than 0.05). No clinical indication of infection was noted in either the corticosteroid or saline control cases.

The effect of tryptophan on postoperative endodontic pain.

Fifty consecutive patients requiring nonsurgical endodontic therapy were the subjects of this pain-control study. Twenty-five subjects received 3 gm of tryptophan in divided 0.5-gm doses over a 24-hour period, beginning before the start of treatment. The other twenty-five subjects received an identically appearing placebo on the same dosage schedule. Pain intensity was evaluated by the subjects on a scale of 0 to 10 (0 = no pain, 10 = severe pain) (1) prior to the start of treatment, (2) after 24 hours, and (3) 1 week later. Results showed that the most meaningful difference was found at 24 hours, when the tryptophan group was significantly better than the placebo group (F = 7.46, df = 1.96, p less than 0.01).

A radiographic evaluation of the periapical status of teeth treated by the gutta-percha--eucapercha endodontic method: a one-year follow-up study of 458 root canals. Part II.

In Part I, which appeared in the last issue, the authors discussed the variations that exist in nonsurgical endodontic therapy with respect to methods of treatment and analyses of success and failure. They then reported on the materials and methods that were used in their clinical study of 458 root canals treated by the gutta-percha--eucapercha method and gave the criteria that were used for the radiographic analysis of success and failure in those cases. In Part II, the results of the one-year follow-up of those 458 root canals is presented. Tables and illustrations are used to substantiate the results.

A radiographic evaluation of the periapical status of teeth treated by the gutta-percha-eucapercha endodontic method: a one-year follow-up study of 458 root canals. Part III.

In Part I which appeared two issues previously, the authors discussed the variations in treatment methods of nonsurgical endodontic therapy and in the determination of success and failure. They then reported on the materials and methods used and the radiographic criteria for success and failure in their clinical study of 458 root canals treated by the gutta-percha-eucapercha method. In Part II which appeared in the last issue, the one-year follow-up results were presented. Some of these results differ from previous investigations. For example, better success was found in (1) necrotic cases with areas of pathosis than in necrotic cases without "areas and in (2) overfilled cases than in underfilled cases. In Part III the authors discuss the possible reasons for these and other findings and give some implications for clinical practice.

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.

Stress, relaxation and saliva: a follow-up study involving clinical endodontic patients.

Dentally induced stress and relaxation-induced anxiety reduction recently have been correlated with salivary changes in private patients treated by a solo endodontist. Hypnosis was shown to be more effective than local anesthesia in anxiety reduction. Dental students and clinic patients were employed in this study in an attempt to replicate the previous findings. One additional salivary variable (pH) was examined. Twenty-nine endodontic clinic patients were treated, each by a different dental student. The patients completed dental anxiety questionnaires and had salivary samples taken prior to, and at the conclusion of, their initial endodontic treatments. Pain and anxiety were managed using local anesthesia, hypnosis, or nitrous oxide-oxygen, either alone or in combination. There were significant anxiety-reduction changes by the conclusion of the visits (p less than 0.001) as measured by increased salivary volume, increased salivary translucency, reduced salivary protein, increased salivary pH and reduced questionnaire-determined anxiety level. Hypnosis and nitrous oxide-oxygen were significantly more effective (p less than 0.05) than local anesthesia in anxiety reduction as measured by salivary changes and questionnaires. It can be concluded that saliva is an easily obtained fluid that can be used to determine levels of stress and relaxation.
