The integrity of the dentinal tubules in the irradiated and non-irradiated samples
was statistically different (p < 0.05). After RDT, 66.7% of the samples were

classification as that before RDT. In the evaluation prior to RDT, the highest
incidence was for dentinal tubules classified as regular (45.5%) and partially
obliterated (47.7%) (
