The effects of early orthodontic force application on pulp test responses.

The effects of orthodontic tooth movement on pulpal responses are of interest to the clinician. Alterations to pulpal physiology may result in altered responses to external stimuli. This pilot project tested a small group of orthodontic patients during the early stages of treatment. Heat, cold and electrical stimuli were applied prior to treatment, after the placement of fixed appliances and after one month of force application. A smaller group was tested after two months of force application. One month after force application there was a lack of response to electrical stimulation but there was continued response to thermal stimulation. The lack of response to electrical stimulation continued in the smaller group up to two months. The results suggest that the outcome of electric pulp testing during orthodontic treatment should be interpreted cautiously. Thermal testing will offer more reliable data.

Pulp testers and pulp testing with particular reference to the use of dry ice.

Pulp testing is mandatory before any operative procedures, invaluable in the diagnosis of pain and is an essential adjunct in the interpretation of radiolucent areas. Methods of pulp testing are reviewed and the use of dry ice for this purpose is discussed in detail. Limitations of pulp testing are considered. Vitality tests are of only limited use in traumatized teeth. The results are only qualitative and not quantitative.

[The reliability of electrical and thermal pulp tests. A clinical study].

A clinical study was conducted to assess the reliability of electrical and thermal pulp tests and to correlate the results with the true pulp status, as this was proved after the access opening, as well as to determine which clinical factors might be associated with the tests reliability. The results showed that pulp tests are reliable in a high grade and that there is no significant difference in their reliability.

Dental pulpalgia contributing to bilateral preauricular pain and tinnitus.

The case of a patient with bilateral preauricular pain and tinnitus is reported. Minimal relief was obtained with traditional temporomandibular disorders therapy, and complete relief was obtained after endodontic therapy. Pulpal conditions that can refer pain are discussed, and recommendations are made to help practitioners identify a possible pulpal etiology for symptoms and tests of temporomandibular disorders.

Analgesic and tolerance studies with AP-237, a new analgesic.

1-n-Butyryl-4-cinnamylpiperazine hydrochloride, AP-237, is a new analgesic that has been reported in both Japan and the United States to have good analgesic activity in animals and is currently undergoing clinical trials. A detailed study of the analgesic and side effect profile of this compound is presented. AP-237 was an effective analgesic in a variety of species by several different routes of administration. Results of studies in an inflamed paw pressure and tail flick test in rats, hot plate and writhing test in mice, tooth pulp test in rabbits and intra-arterial bradykinin test in dogs are reported. AP-237 had a low physical dependence liability in rodents as measured by a mouse jumping test and a lack of withdrawal syndrom. Tolerance and cross tolerance results are reported. AP-237 is compared to morphine and pentazocine in most tests.

Reliability of electric pulp testing after pulpal testing with dichlorodifluoromethane.

The purpose of this study was to determine if the sequence and interval between electric pulp testing and cold vitality testing with dichlorodifluoromethane affects the reliability of pulpal diagnostic testing. Sixty vital teeth in 15 volunteers were tested. Ten endodontically treated teeth were used as negative controls. After isolation and asepsis techniques, baseline threshold responses from a digital electric pulp tester were recorded from the maxillary incisors. A dichlorodifluoromethane-saturated cotton pellet was applied to teeth 8, 9, and 10. Electric pulp testing was repeated at 30-s, 1-min, and 2-min intervals on all test teeth after the cold test. The level of responses were recorded and statistically analyzed. The results of this study indicate that electric pulp testing is not adversely affected by the use of dichlorodifluoromethane.

Pulp test response of the maxillary anterior teeth in cleft palate patients.

The relative pulpal responsiveness of the six maxillary incisors to electrical and cold thermal stimuli was tested in patients with complete unilateral and bilateral clefts. The six maxillary anterior teeth were tested at random to electrical stimuli. After a 5-minute interval, the same teeth were tested at random to cold stimuli with an ice pencil. Unilateral and bilateral cleft palate patients had statistically significant higher mean electrical pulp test thresholds for the maxillary anterior teeth than the noncleft palate patients. No statistically significant difference between unilateral and bilateral cleft palate patients was found in electric pulp test responses of the maxillary anterior teeth. No statistically differences in electric pulp test responses and cold test responses of the maxillary anterior teeth in both cleft palate and noncleft palate individuals based on differences in sex were observed. No statistically significant difference in cold test responses were observed between cleft palate and noncleft palate patients. Cleft palate patients who completed orthodontic treatment within 1 year of testing showed elevated mean electrical pulp test thresholds as did noncleft palate patients who received orthodontic treatment within 1 year of testing.

[Injuries to permanent teeth. Part 1: diagnosis of the tooth injury].

Diagnostic and therapeutic interventions following dental injuries are not part of the routine practice in the dental office. Quite often, these patients are emergency cases who seek treatment after normal office hours. The objective of this and the future papers is to present the current treatment concepts in dental traumatology at the School of Dental Medicine, University of Berne. The fruitful cooperation in the field of dental traumatology between the Department of Oral Surgery and Stomatology, and the Department of Conservative Dentistry (including pediatric dentistry and endodontology), is based on the interdisciplinary approach that has been established four years ago. Following discussion and evaluation of such treated cases, and considering current clinical and experimental references, the said concepts have been worked out. The present paper describes the diagnostic measures following injuries to the permanent teeth. Subsequent papers will illustrate our therapeutic concepts of injuries to the periodontal and dental hard tissues of permanent teeth.

[Cracks in the dental enamel caused by sensitivity testing with CO2 snow and dichloro-difluoromethane--a comparative in vivo study].

With the aid of permeating dye and standardized fluorescence UV-photography, the reaction of subjects and enamel to the application of two pulp vitality testing methods (frozen carbon dioxide and Frigen -pellets) was examined. The enamel lamella system, the diffusion of temperature changes through the tooth crown and the thermodynamic pattern of enamel and dentine are described in detail. Structural changes of enamel as well as the subject's reaction times to a cold stimulus during the vitality tests are documented and the data are compared. Frigen caused less enamel changes than did frozen carbon dioxide. The subject's reaction times were similar for both methods. There were no differences between the methods with regard to the number of reopened, extended and newly created enamel fissures. However, the length, width and depth of these fissures proved to be less pronounced for Frigen than for carbon dioxide. Clinical implications of the results are discussed.

Transient apical breakdown following subluxation injury: a case report.

Transient apical breakdown has been reported to occur in cases in which a periapical radiolucency develops and resolves without treatment following luxation injury. Diagnostic errors are inevitable if periapical breakdown is used as the sole criterion or as an overriding criterion in the decision to initiate root canal treatment. A clinical case report is presented in which transient apical breakdown occurred after a subluxation injury. The threshold to sensitivity tests increased yet sensitivity remained positive with the appearance of the periapical radiolucency. The decision was made not to initiate root canal treatment in spite of the radiographic appearance periapically. At the 10-month recall the tooth remained responsive to sensitivity tests and the apical radiolucency had disappeared.

Detection of pulpal circulation in vitro by pulse oximetry.

Evaluation of pulse oximetry as a potential method of determining pulp vitality was the subject of this research. An in vitro model of pulpal circulation was fabricated to test the design for a dental pulse oximetry sensor. Blood samples equilibrated with hypoxic gas mixtures were circulated through the model by a peristaltic pump. A pulse was simulated by introduction of gas bubbles into the blood circulation. Pulse oximeter readings for saturation were recorded and compared with blood gas analysis results. Statistical analysis revealed no difference between pulse oximetry and blood gas analysis with a highly significant correlation coefficient. Clinical evaluation of this application is currently in progress.
