[Elevation of the threshold in the rabbit dental pulp test with coumarin: unspecified (local) effect rather than analgesic activity?].

The antinociceptive efficacy of Coumarin was tested in mice, rats, and rabbits. No increase in threshold for the antinociceptive reaction was observed in the hot plate test and tail flick response in mice and rats. Using the tooth pulp test in rabbits, the threshold for the licking reaction was increased. This effect was dose dependent and could, at least partially, be antagonized by Naloxone. Because there is no direct opiate-like activity of Coumarin, these results suggest that the effect may be mediated by the release of endogeneous opiate-like peptides. It remains totally unclear why this effect could only be demonstrated in one particular test in one species.

[Testing the electric resistance as an objective diagnostic test in dental pulp diseases].

The authors test by means of a measuring device of high precision the resistence of health or sick human pulpa, comparing it to them of gums, excluding in the same time the sensibility of the patient in question. The authors corroborate the obtained dates with clinical symptomatology and the histopathological photos, discussing the possibility of objective electrical test as an expedient in the diagnosis of pulpa-affections.

A clinical evaluation of the electric pulp tester as an indicator of local anesthesia.

Local anesthesia is the primary method in dentistry to control patients' pain. However, several studies have shown that profound anesthesia is not always achieved. The electric pulp tester has been used to measure the level of local dental anesthesia during endodontic therapy. However, no study has been performed that evaluates the ability of the electric pulp tester to predict the efficacy of local anesthesia prior to as operative procedure. If ineffective anesthesia could be predicted, supplemental injections could be administered to alleviate the anesthetic problem. The purpose of this study was to evaluate the ability of the electric pulp tester to measure the level of local anesthesia prior to operative treatment. The study was performed in vivo on patients requiring operative therapy. All teeth were pulp tested preoperatively for vitality using the electric pulp tester. After injection of local anesthetic, traditional parameters of dental anesthesia were verified (lip numbness, mucosal sticks). Teeth were then retested with the electric pulp tester and the results recorded. The teeth were them prepared for restoration using conventional instrumentation, and the patient's level of anesthesia evaluated using a visual analog scale. The electric pulp tester readings were compared to the patient's responses using Fisher's Exact test (two-tail). The results indicate that the electric pulp tester can be a valuable tool in predicting potential anesthetic problems in operative (restorative) dentistry.

An unusual instance of leukemic infiltrate. Diagnosis and management of periapical tooth involvement.

The clinical course of an adult patient with relapsed acute myelogenous leukemia and leukemic infiltrate periapical to the dentition is described. While the oral symptoms were indicative of pulpal disease requiring dental therapy to resolve the patient's complaint, roentgenographic, dental pulp testing, and histologic analysis revealed extramedullary infiltrate apical to a mandibular molar. The findings developed coincident with relapse of leukemia; the medical and dental testing described above were essential in establishing an accurate diagnosis. While most oral leukemic infiltrates affect the gingiva, in this patient the infiltrate involved periapical tissue which was not clinically observable.
