  We consider an analysis of potentials related to Schr\"odinger-type equations
for scalar fields in a 5D AdS black hole background with dilaton in order to
get melting temperatures for different hadrons in a thermal bath. The approach
does not consider calculations of spectral functions and it is easy to get
results for hadrons with an arbitrary number of constituents. We present
results for scalar mesons, glueballs, hybrid mesons and tetraquarks, and we
show that mesons are more resistant to being melted in a thermal bath than
other scalar hadrons, and in general the melting temperature increases when
hadrons contain heavy quarks.
