The use of androgenic anabolic steroids (AAS) has increased significantly among
athletes in Brazil and other countries. These drugs alter the physiological
behavior of bone and muscles, also affecting these structures in masticatory
system. This paper aims to evaluate bone and dental changes in users of AAS, as
well as the incidence of temporomandibular dysfunction (TMD), compared to
athletes not using AAS. Eight athletes were equally divided in two groups, AAS
users and non-users. The groups were evaluated using Helkimo index, McNamara
cephalometric tracing and cast analysis. The AAS users presented more intense TMD
signs and symptoms (Di total value, P = 0.096, Mann-Whitney test), increased
cephalometric measures (Co-A, P = 0.020, Mann-Whitney test) and Angle Class II
malocclusion, compared to the non-users. These results suggested that the use of
AAS alters masticatory structures and increases the incidence of TMD.
