Upon examination, the masseter and temporalis muscles are tender to palpation.Diagnosis: M79.11, A patient who frequently chews gum reports persistent jaw pain and difficulty opening their mouth wide.Diagnosis: M79.11, Following a dental procedure that required prolonged opening of the mouth, a patient experiences soreness and pain in their jaw muscles. Diagnosis: M79.11
