RESUMO
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.
