Experimental Neurology, 2001 Recent evidence suggests interactions between primary afferent nociceptors and postganglionic sympathetic efferents in the pathogenesis of inflammation. The effect of unilateral removal of the superior cervical ganglion on the innervation pattern of nerve fibers immunoreactive (IR) to calcitonin gene-related peptide (CGRP), substance P (SP), and ...

Acta Odontologica Scandinavica, 1971 The purpose was to study the effect of amalgam with known relative sealing properties. In 28 bicuspids deep cavities were prepared and filled according to the wet technique, 14 with amalgam A, shown to give a good seal, and 14 with another amalgam, B, which gave a comparatively less good seal. Seven teeth in each group were extracted after 1 week and 7

Repair in the human dental pulp following cavity preparation
Archives of Oral Biology, 1970Abstract The reactions following cavity preparation with a Borden air turbine handpiece were studied in ninety-three caries-free young premolar teeth. Immediate damage to the dental pulp was greater in air-cooled than water-cooled specimens and this greater degree of injury was evident up to 15 days post-operatively.

The Effect of Cavity Preparation on Substance P Expression in Human Dental Pulp
Journal of Endodontics, 2005Substance P (SP) plays an important role during neurogenic inflammation of dental pulp. The purpose of this study was to use a radioimmunoassay for determining the effect of cavity preparation on SP expression in healthy human dental pulp. Ten pulp samples were obtained from healthy premolars where extraction was indicated for orthodontic reasons. Deep

A study of the dental pulp cavity of mandibular first permanent molars in the Kuwaiti population
Journal of Endodontics, 1998This study documented the complexity of the root canal system in the mandibular first permanent molar. Forty-nine plastic replicas were used from mandibular first permanent molars obtained from young Kuwaitis. Results revealed that the tooth had 2 canals, 3 canals, and 4 canals 6.1%, 67.4%, and 26.5% of the time, respectively. The number, distribution,
