There is a lack of scientific evidence about the physiopahotology, epidemiology, etiology, diagnosis and management of treatment of Temporomandibular Disorders (TMD). Many attempts have been made to establish a cause-effect relationship between oclusal factors and TMD, but there are conflicting findings among the studies, due in part to the variation in definitions and systems used to describe and classify the occlusal contact pattern. There is no description regarding the mandibular position when examining occlusal contacts, which may account for the inconsistencies among the findings of the studies. Edge to edge position in lateral movement has been used to classify the occlusal contact pattern (canine guidance or group function), occlusal contacts that occurred during the complete lateral movement have not been registered in most of the studies. The purpose of this study was to analyze the relationship between the Pattern of occlusal contact in intermediary position in lateral movements, registering occlusal contacts in various mandibular lateral positions, and the TMD, under several anxiety conditions. In determining the anxiety conditions, we used the Spielberger State-Trait Anxiety Inventory (STAI), which was validated for the sample studied. Ninety four students (26 men, 68 women) between the ages of 18 to 25 years were selected from a group of 407 students of the seventh semester of the School of Dentistry of Universidad de San Martín de Porres. Each individual completed the STAI, then their TMD was evaluated using the Helkimo Index. The occlusal contacts were recorded with shim stock (8 μm thick) in four lateral positions on both sides; 0.5 , 1, 2 mm from maximum intercuspation, and edge to edge position. Prevalence of 87.2 % was found in this study and a significant association in the level of state anxiety in women (p<0.05). Statistycal analysis was performed between TMD an the pattern of occlusal contacts in each of the four lateral positions examined on both sides. Significant association was only found, in the 0.5 mm position on left side and the TMD (p<0.05). Significant associations were found only in trait anxiety when using the stratified analysis controlling the anxiety variable in two stratum with TMD, in 0.5 mm left lateral position. On the basis of the results of this study, the relationship between the occlusal contacts in lateral movements and TMD would be questioned due to the weakness of the statistical relationship found. Effect modification is present in the stratum analyzed of anxiety, this condition would show a probable role for the presence of TMD under risk occlusal conditions.
