Abstract

Background: Dentinal tubules play an important role in transferring stimuli and local irritants to the pulp. Aim: This invitro SEM study aims to analyse the occluding effect of Er:YAG Laser on exposed dentinal tubules. Materials and Methods: 60 tooth samples prepared from healthy maxillary first pre-molars extracted due to orthodontic reasons were grouped randomly into two groups of 30 samples each: Group I: control group (C) & Group II: Er:YAG laser group (LG). The group-I samples acted as
control to record the diameter of patent dentinal tubules and group-II samples were treated with Er:YAG laser of setting 1.3W, 100mJ, 3Hz, 60s twice to study its occluding effect on the tubules. The samples were then subjected under SEM, to record the data and microphotographs and were then statistically analysed using the unpaired t-test.
