THE DENTAL PULP

DEFINITION

The pulp is a soft tissue of mesenchyme origin residing within the pulp chamber and root canals of teeth..

The close relationship between the odontoblasts and dentin is one of several reasons why the dentin and pulp should be considered as a functional entity, sometimes referred to as the pulp-dentin complex

INTRODUCTION

Non-mineralised vascular tissue Responsible for the formation of

dentine Contained within pulp chamber and

root canal of the tooth. Remains active through out life.

THE DENTAL PULP

COMPONENTS OF DENTAL PULP

FOUR ZONES

Odontoblastic zone – located at the periphery of the pulp adjacent to the dentine.

Cell-free zone – beneath the odontoblast is a cell – free zone also known as the zone of Weils.

Cell-rich zone – beneath the cell-free zone is an area with a high cell density.

Pulp Core – is the area where major blood vessels and nerves are found

HISTOLOGY OF DENTAL PULP

A-odontoblastB-cell-free zone (of Weil)C-cell-rich zone

NORMAL FEATURES OF PULP

A normal tooth is (a) asymptomatic and exhibits a (b) mild to moderate transient response to thermal and electric pulpal stimuli; and (c) the response subsides almost immediately when such stimuli are removed. (d) The tooth and its attachment apparatus do not cause a painful response when percussed and palpated
