Pulpal irritants
نویسنده
چکیده
The dental pulp is characterized as a connective tissue and as such it is not considered an external tissue, yet its exposure to external stimuli is constant. This is due to a number of factors including the permeability of attrited or disrupted enamel as well as that of physiologic dentin and cementum. The pulp is extraordinarily sensitive to its external environment. Once thought to be a vestigial organ, it is now understood that the dental pulp is an important tissue whose role in the defense of the dentition may be as significant as its role in odontogenesis.

Pulpal and periradicular pathosis are the result of microbial, mechanical, or chemical invasion. Microorganisms are the main irritants of pulpal and periapical tissues. The goal of the obturation is to obtain a fluid-tight seal of the root canal system from its coronal aspect through its apical extent to preserve from the irritants.. Root apices have morphological irregularities in teeth with p...
متن کاملEffect of local anesthesia on pulpal blood flow in mechanically stimulated teeth
Whenever the tooth dentin-pulp complex is affected by caries, attrition, erosion, chemicals and abrasion, pulpal response to these injuries can stimulate inflammatory activity. Although the pulp injury caused by these irritants can be important, in many cases the most severe tissue trauma is not a direct result of these environmental or accidental events, instead, it results from the surgical t...
متن کاملAn in vivo evaluation of the change in the pulpal oxygen saturation after administration of preoperative anxiolytics and local anesthesia.
Background. Given the influence of systemic blood pressure on pulpal blood flow, anxiolytics prescribed may alter the pulpal blood flow along with the local anesthetic solution containing a vasoconstrictor. This study evaluated the impact of preoperative anxiolytics and vasoconstrictors in local anesthetic agents on pulpal oxygen saturation. Methods. Thirty anxious young healthy individuals wit...
متن کاملNMDA receptor mechanisms contribute to neuroplasticity induced in caudalis nociceptive neurons by tooth pulp stimulation.
We recently demonstrated that application of mustard oil (MO), a small-fiber excitant and inflammatory irritant, to the rat maxillary molar tooth pulp induces significant and prolonged increases in jaw muscle electromyographic (EMG) activity that are suggestive of central neuroplasticity. Because small-fiber afferents, including pulp afferents, access nociceptive neurons in trigeminal (V) subnu...

tion, necrosis, and dystrophy are legion, ranging from bacterial invasion to hereditary dwarfism. Without question, bacterial invasion from a carious lesion is the most frequent initial cause of pulp inflammation. Paradoxically, an alarming amount of pulp involvement is induced by the very dental treatment designed to repair the carious lesion. An increase in automobile and cycle accidents, as ...
