EXCITATION OF TOOTH PULP AFFERENTS WITH ELECTRICAL CURRENT

Acupuncture & Electro-Therapeutics Research, 1984
Electrical excitation of tooth pulp afferents seems to be a most accurate and reproducable method to produce graded pain with minimal injury of the tissues. Besides electrical current only thermal stimulation may activate pulp nerves of an intact tooth, but this method lacks the precision of the electrical stimulation and bears more risk of injury ...

The effect of experimental tooth intrusion on pulp and dentine

Oral Surgery, Oral Medicine, Oral Pathology, 1971
Abstract A study of sixty teeth from children 10 to 13 years of age reveals that marked changes may occur in the dentine and pulp as a result of tooth intrusion with continuously acting forces. The pulp reactions were most manifest in teeth in which the apical area was complete. Alterations in apical anatomy were found only in teeth in which the root

Pulp Vascularization during Tooth Development, Regeneration, and Therapy

Journal of Dental Research, 2017
The pulp is a highly vascularized tissue situated in an inextensible environment surrounded by rigid dentin walls, with the apical foramina being the only access. The pulp vascular system is not only responsible for nutrient supply and waste removal but also contributes actively to the pulp inflammatory response and subsequent regeneration.

Human pulp responses to in-office tooth bleaching

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2010
To evaluate and compare the responses of human incisor and premolar pulps after bleaching.A bleaching agent with 38% hydrogen peroxide (H(2)O(2)) was applied on the buccal surface of 10 sound lower teeth (G1: 6 premolars; G2: 4 incisors) for 45 minutes.

Jaw depression elicited by tooth pulp stimulation

Experimental Neurology, 1970
Abstract Stimulation of tooth pulpal nerves in both anesthetized and alert cats elicited a vigorous jaw depression reflex. The threshold for jaw depression in the chronic preparation remained stable for as long as 4 months. Disappearance of the jaw depression response following endodontic therapy indicated that the response was not caused by spread ...

Age estimation in an Indian population using pulp/tooth volume ratio of mandibular canines obtained from cone beam computed tomography.

Journal of Forensic Odonto-Stomatology, 2011
The present study assessed the suitability of pulp/tooth volume ratio of mandibular canines for age prediction in an Indian population. Volumetric reconstruction of scanned images of mandibular canines from 140 individuals (aged ten - 70 years), using ...

Transmedian innervation of canine tooth pulp in cats

Experimental Neurology, 1974
Abstract The present study was designed to determine the extent to which the pulpal nerves of teeth in the cat receive a bilateral innervation from first order trigeminal afferent fibers. Bipolar electrodes were implanted into the predentin of upper and lower canine and premolar teeth on both sides of the jaw and into the left and right trigeminal ...

Tooth pulp transcapillary osmotic pressure in the dog

Archives of Oral Biology, 1969
Abstract The purpose of these experiments was to measure the osmotic pressure across the tooth pulp capillary wall in dog canine teeth. Osmotic pressure was calculated by subtracting pulp tissue pressure from intracapillary pressure. Tissue pressure was measured by the pulp tap technique.
