Ultrasound (US) therapy is used to reduce pain and inflammation and to accelerate healing after soft tissue injury. However, there is little objective evidence of its effectiveness and the mechanisms which may cause these effects are unknown. In a placebo-controlled double-blind clinical trial we examined the contribution of placebo and massage effects in ultrasound therapy following bilateral surgical extraction of lower third molars.
Trismus is a pathological condition of the muscles of mastication which commonly affects patients who have undergone dental procedures, oral surgery, and radiation therapy for head and neck cancer. The purpose of this case report is to describe the use of dynamic splinting, a noninvasive modality to reduce trismus which occurred in a patient following multiple dental procedures. A 26 year old man of African descent was referred for severe trismus and pain following three dental procedures on the lower right molars.
INTRODUCTION: Orofacial pain and pain in the muscles of mastication are frequent symptoms of temporomandibular disorder. The masseter is the closet masticatory muscle to the surface and has the function of raising and retracting the mandible. This muscle has considerable strength and is one of the main muscles involved in the shredding of food It is therefore of utmost importance in the masticatory cycle and generally the most affected by pain and spasms.

Surgical treatment and complications in patients with mandibular fractures leads to a significant degree of tissue trauma resulting in common postoperative symptoms and signs of pain, facial swelling, mandible dysfunction and limited mouth opening (trismus). Beneficial effects of local cold treatment on postoperative swelling, oedema, pain, inflammation and haemorrhage, as well as the reduction of metabolism, bleeding and haematomas have been described.
Pulsed electromagnetic energy is being increasingly employed to reduced symptoms and enhance the healing process following tissue injury. A double-blind placebo-controlled trial has been carried out to assess the value of electromagnetic energy in third molar surgery, but no significant benefit has been found.
