Detecting Efficiency of pit and Fissure Sealant in Penetrating the Full-Depth of Occlusal Fissures Using Optical Coherence Tomography.

Objectives: This study aimed to evaluate the penetrability of pit and fissure sealant (PFS) in covering the full-depth of different occlusal fissure depths using swept-source optical coherence tomography (SS-OCT).
Methods: Ninety-seven investigation sites of occlusal fissures on fifteen premolars with ICDAS 01 or 02 were categorized using SS-OCT into four groups (smooth, shallow, intermediate, and deep fissures) based on the classification used by Ito et al. (2016). After pit and fissure sealant placement, cross-sectional images of these fissures were observed again with SS-OCT. Randomly selected samples from each group were examined under stereomicroscope and the resuting cross sectional images were qualitatively compared with OCT images.
Results: The result of this study showed that pit and fissure sealants (PFS) can fully penetrate the smooth fissures (100%) followed by shallow fissures (94.2%) and intermediate fissures (47.6%). There was incomplete PFS penetration in all deep fissures (100%). The depth of PFS penetration into fissures observed using OCT B-scans (cross sectional images) were comparable with cross sectional stereomicroscope images.
Conclusions: In conclusion, the depth of the fissure will largely affect the penetrability of pit and fissure selants into the fissure.
