The purpose of this study was to compare the cleansing effect of fissure cleansing
techniques for the pit and fissure sealants, and the penetration condition of the sealant
material according to the fissure cleansing techniques. Thirty six extracted human
premolars or third molars treated with conventional pumice prophylaxis (experimental
group 1), done with air polishing device (experimental group 2) or not done at all
(control group). The surfaces of each group were observed with SEM (Scanning
Electron Microscope). After each treatment was performed, all group of teeth were
applied with light polymerizing sealant material. The teeth with sealant were sectioned
to 3 pieces with carborundum disc parallel to the tooth long axis and stained with
Asian blue. The sectional pieces were observed with stereomicroscope to investigate the
filling condition of the sealant materials according to the longitudinal-sectional fissure
shape.
1. In both of the control and experimental group 1, much residual integument and
pumice particles were observed in the fissure, but in the experimental group 2, residue
and powder for air polishing device in the fissure rarely were seen,
2. In the U shape pit and fissure, the sealant were completely penetrated to the bottom
of the pit and fissure in all the groups
3. Complete penetration ratio of the sealant to the V shape fissure were on the
decrease, experimental group 2, experimental group 1 and control group in sequence.
4. By the penetration condition of the sealant in the bottle neck shape fissure, complete
penetration was seen in only one case experimental group 2.
5. In the comparison of the penetration degree by the measurement of the cross-
sectional width of the sealant, the experimental group 2 was the best
