Relationship between unilateral chewing and temporomandibular joint pain
Keywords:
Temporomandibular joint pain, Unilateral chewingAbstract
In the authur’s experience in treating patients with temporomandibular joint pain. Unilateral chewing habit prior the pain happens was frequently found together with temporomandibular pain. The unilateral chewing was found both ipsilateral and contralateral to the pain side. It is logically understanding that ipsilateral chewing can cause overload to the joint and cause pain. But a large number of contralateral chewing was also observed. It seems illogically that chewing on one side can cause pain to the contralateral temporomandibular joint. So this study purposes is to find how much unilateral chewing there are in patients with temporomandibular pain and the ratio of unilateral chewing and contralateral chewing.
Results : There were 39 men and 111 women . Had 67 right temporomandibular joint pain, 81 left temporomandibular joint pain and 3 bilateral temporomandibular joint pain . In the unilateral temporomandibular joint pain patients, there were 85 ipsilateral chewing (58%), 45 contralateral chewing (30%) and 18 equally chewing (12%)
Conclusion: There are correlation between unilateral chewing and temporomandibular pain. Ipsilateral chewing is frequently found together with temporomandibular pain but it is not surprising to find contralateral chewing together with temporomandibular joint pain.
