A Correlation between Clinical Classification of Dental Pulp and Periapical Diseases with its Patho Physiology and Pain Pathway

Abstract

Background: Dental pain due to pulpal involvement is difficult to diagnose due to the apparent inaccessibility of pulp to the clinical tests, indistinct symptoms, and referred toothache originating from the periodontal tissues. Though we have various clinical classification systems to categorize pulpal diseases, we are yet biased about the exact pathophysiology and pain pathway associated with it. Dental pulp has a complex physiology, and so is its pathophysiology.

Aims & objectives: To concisely reviews the basic understanding of the pathophysiology of pulp, pain pathway, and its correlation with the classification of various clinical conditions of pulpal inflammation and periapical diseases.

Methodology: Literature search on pulpal diseases and pathophysiology from the sources: MEDLINE, PubMed, Web of Science and Cochrane Databases dated from 1965 till December 2020 was carried on to collect 163 articles.

Results: Filtered search on the pathophysiology of pulp, pain pathway, and classification of various clinical conditions of pulpal inflammation resulted us to precise 36 articles required for our understanding and demystifying the correlation.

Conclusion: The emphasis should be laid on understanding the minute changes occurring inside the pulp in due course of inflammation to aid its diagnosis and a treatment plan accordingly.
