Indiana University-Purdue University Indianapolis (IUPUI) / While advances in lasers for soft tissue applications have
drastically increased its usage in dentistry, laser use for hard tissue
still needs development. This study was conducted to determine the
difference between permanent and primary enamel after their
exposure to the Nd:YAG laser. Four parameters were studied:
Surface topography, acid resistance, surface hardness and caries-like
lesion depth creation.
Differences between lased primary and permanent teeth were
seen in two parameters. Calcium disassociation during acid attack
was significantly higher for lased primary enamel (p=0.0126), and
lased primary enamel became softer while permanent enamel
became harder (p=0.0001).
While this study adds to the body of knowledge related to hard
tissue laser use, further evaluation and research is needed prior to
the routine use of the laser on primary enamel.
