Abstract
Dental pain is the most common reason due to which patient seek dental treatment. Pain occur due to diseases involving pulp and periradicular tissues, as this tissues are richly innervated and have ample of blood supply. Also it is enclosed by surrounding tissues that are incapable of expanding, such as dentin and also has terminal blood flow and small-gauge circulatory access the periapex. All of these characteristics severely constrain the defensive capacity of the pulp tissue when faced with the different aggressions it may be subjected to. In addition to above mentioned characterstics, pulp tissue can also be affected by a retrograde infection, arising from the secondary canaliculi, from the periodontal ligament or from the apex during the course of periodontitis. this review article basically concentrates on structure of pulp, classification of diseases related to pulp and periradicular tissue and detailed explanation of diseases
Highlights
(1) The dental pulp consists of vascular connective tissue contained within rigid dentin walls
The first and foremost reaction of pulp tissue to irritation is “Inflammation”, but the basic disease process that is involved in pulp and periapical disease is “Infection”
Infection can start from pulp and spread to periodontal tissue and vice versa is possible
Summary
Pulp has been described as a highly resistant organ and sometime as an organ with little or no resistance as its resistance depends on cellular activity, nutritional supply, age and other metabolic and physiologic parameters. [1] The dental pulp consists of vascular connective tissue contained within rigid dentin walls. [2] It is the principal source of pain within the mouth and the major site of attention in endodontics and restorative treatment. [3].

Stimuli----> deposition of secondary dentin ----> reducing size of pulp chamber and volume-----> reduces the cellular, vascular and neural content of the pulp results in atrophy [3]
