Indiana University-Purdue University Indianapolis (IUPUI) / Erosive tooth wear (ETW) is an emerging dental condition manifested clinically
as tooth surface loss, eventually impairing the teeth’s structural integrity, function, and
esthetics. Both research and practice are in need of a quantitative, non-destructive method
to monitor ETW. Cross-polarization optical coherence tomography (CP-OCT), an
advanced imaging tool, shows great potential to fulfill this need, but its feasibility and
shortcomings remain unclear. In this dissertation, I explored the capability of CP-OCT to
monitor ETW in three in vitro studies, one per chapter. Chapter 2 investigated the effects
of enamel surface roughness and dental erosion severity on CP-OCT dental surface loss
measurements. Chapter 3 tested the effects of enamel surface roughness and dental
erosion on CP-OCT enamel thickness measurements at different simulated wear levels.
Chapter 4 explored the ability of CP-OCT to quantify the thickness of natural and wornout
enamel surfaces and to estimate longitudinally the wear depths resulting from
simulated wear. I concluded: (1) enamel surface roughness did not affect CP-OCT
measurements of enamel surface loss, however, the estimated error limited the
appropriate assessment of the initial stages of dental erosion surface loss using CP-OCT;
(2) enamel surface roughness and dental erosion did not affect CP-OCT enamel thickness
measurements, and the CP-OCT differentiated the simulated enamel wear levels; and (3)
CP-OCT quantified thickness of natural enamel before, during, and after the tooth wear
simulation and allowed wear depth estimation following the simulated wear. / 2021-07-03
