Treatment of Dentinal Hypersensitivity by means of Nd:YAP Laser: A Preliminary In Vitro Study

Figure 2

SEM view of Nd:YAP lased dentin treated previously with EDTA (18%). SEM view of exposed dentine with Nd:YAP laser beam at 0.9 W (a) and 1.4 W (b). We can only notice a slight tubules narrowing. Arrows show the graphite particles still existing on the dentinal surface (not disintegrated by the laser beam). Magnification: 3000x.
