Research Abstract |
This study aimed to clarify pulpal responses to GaAlAs laser irradiation. The output energy determines pulpal healing patterns after GaAlAs laser irradiation : the higher energy induces the apoptosis in the affected dental pulp including odontoblasts followed by active cell proliferation in the intense HSP-25-immunoreactive areas surrounding the degenerative tissue, resulting in abundant tertiary dentin formation. Thus, the optimal GaAlAs laser irradiation elicited intentional tertiary dentin formation in the dental pulp.
