Abstract: Background: Healthy dentition is a pre requisite for good esthestic, phonectics and self-esteemed of an individual. In India 40-80% of population have one or the other class of malocclusion with varying severity. There are various methods used of evaluation of TMJ dysfunction like tomogram, MRI, but Helkimo is a pioneer in developing indices by which severity can be clinical evaluated Temporomandibular disorder is a multifactorial disease. Awareness regarding this is an important aspect in today’s scenario. In Orthodontic practice awareness regarding TMD is utmost important. A parallel group trial study is to analyze & compare presence and intensity of TMD symptoms in skeletal class I, class II (vertical & horizontal) using Helkimo and Craniomandibular index. This study will help us in day to day Orthodontic practice. Objective: Evaluation of presence & intensity of TMD symptoms in skeletal class I, class II (vertical & horizontal) cases using Helkimo index & Craniomandibular index. Evaluation of presence & intensity of TMD symptoms in skeletal class I, class II (vertical & horizontal) cases using Craniomandibular index Material and methods: Total 90 patients (Class I, Class II (vertical & horizontal)), in age range of 14-25 years, will be selected. For every patient, Helkimo and craniomandibular index will be taken. Scores will be recorded and will be compared. The results compared will give us which skeletal pattern is prone for TMD.Results: All the results that will be obtained in each group will be compared and give an expected result which skeletal pattern is more prone to temporomandibular disorders. Conclusion: This study will help us to know which skeletal pattern is more prone to TMD as well as help in early screening of TMD disorders.
