Results: The data obtained was processed to see the relationship of each variable. Statistical tests used Kendall's rank correlation and Spearman's rank correlation to see further interrelationships of significance between groups. The correlation value W = 0.58 with chi-square = 34.480 and p-value = 0.00000016 (p-value <0.01) which was statistically significant. Conclusion: The results showed significant relationship between malocclusion, bruxism, cliking sound and hypertonus of masseter muscle in autism spectrum disorders. However, there was no association between malocclusion with bruxism, malocclusion with clicking, malocclusion with hypertonus of masseter and bruxism with clicking.
