Abstract
Like other connective tissues, pulp tissue has the potential to heal.
Characteristics of exposed pulp tissue that advance healing, include
reorganization of damaged soft tissue, differentiation of odontoblast-like
cells from subodontoblast cells, and repair of exposed pulp tissue with
reparative dentin bridge formation.
The potential for recovery after pulp exposure depends on several
factors, as the pulp status, pre and post-operative prevention of bacterial
infection, size of exposure and the efficacy of treatment strategy.
Direct pulp cappmg means covering the exposed pulp surface with
sterile biocompatible material to maintain its vitality and preserve its
functional and biologic activities. Inducing hard tissue formation by pulp
cells as an ultimate goal of capping material use has been widely accepted.
Because of its low-grade irritation of the traumatized pulp tissue, calcium
hydroxide [Ca(OH)2] has been the material of choice for pulp capping.
Known disadvantages for this material include gradual degradation, tunnel
defects in dentinal bridge, and poor sealing properties. Mineral trioxide
aggregate (MTA) has been introduced as a suitable material for direct pulp
capping.
Proper healing of the exposure site requires proper prevention of
bacteria as well as proper seal for the exposure site, to prevent leakage.
Irrigation of the exposed sites with antibacterial and anti-inflammatory
material may enhance the healing potential of the exposed dental pulp.
That’s why the target of this study was directed toward examination of the
effect of different irrigating solutions and capping materials on healing of
exposed pulp.
