Mandibular Tracking and the use of Ultra Low Frequency TENS (ULF-TENS) in the Diagnosis and Treatment of TMJ/ CFP
•Over 40 controlled studies that support the rationale for mandibular jaw tracking.
•Over 45 international supporting studies supporting the use of the TENS for TMD/CFP diagnosis and treatment.
•Research clear that low frequency TENS has a high degree of specificity when utilized for craniofacial pain and is both safe and efficacious for muscle relaxation and pain control.
•Numerous other supportive studies
ULF-TENS stands for Ultra Low Frequency Transcutaneous Electrical Nerve Stimulation. This stimulation is used in neuromuscular dentistry as a therapy specific for the treatment and resolution of TMD and cranio-cervico-facial conditions. The TENS delivers an electronic impulse through the nerves that control the masticatory, neck and facial muscles. The rhythmic pulsing of the nerves relaxes the muscles and allows us to determine the correct relation of the mandible to the base of the cranium. It also relieves pain and shortening of the muscles of the face and neck caused by spasms and tension. In addition, the mandible settles to a position which is conducive to relaxed musculature. Use of the TENS involves the placement of electrodes bilaterally in the pre-auricular area, just lateral to the coronoid notch as well as on the posterior triangle of the neck. The current emanating form the electrodes stimulates both the sensory and motor divisions of the fifth, seventh and eleventh cranial nerves. The effectiveness of the TENS therapy is documented by EMG recordings.
The TENS is applied most effectively when monitored in conjunction with CMS and EMG recordings simultaneously in objectively documenting and diagnostically gathering information before, during and after treatment.
There is evidence to support the effectiveness of such diagnostic instrumentation as verified and confirmed by the American Dental Association (ADA) and the Food and Drug Administration (FDA).
ADA “Seal of Acceptance” and FDA approval
•The American Dental Association’s Council on Scientific Affairs has awarded surface electromyography (SEMG), Computer Mandibular Scanning (CMS), and Sonography its “Seal of Acceptance”, as diagnostic aids in the management of temporomandibular disorders.
(Report on Acceptance of TMD Devices, ADA Council on Scientific Affairs, JADA, Vol. 127, November 1996)
•The U.S. Food and Drug Administration has granted 510k status to each of these mentioned devices for use in the diagnosis and management of TMD in my practice. This reflects that the U.S. Government and the dental profession acknowledges the safety and efficacy of the devices as recording and measuring devices used in the diagnosis and management of TMD and orofacial pain.

The pathological changes of subchondral bone during osteoarthritis (OA) development in the temporomandibular joint (TMJ) are poorly understood. In the present study, we investigated the longitudinal alterations of subchondral bone using a rat TMJ-OA model developed in our laboratory. Changes in bone mass were examined by micro-CT, and changes in osteoblast and osteoclast activities were analyzed by real-time PCR, immunohistochemistry, and TRAP staining. Subchondral bone loss was detected from 8 weeks after dental occlusion alteration and reached the maximum at 12 weeks, followed by a repair phase until 32 weeks. Although bone mass increased at late stages, poor mechanical structure and lower bone mineral density (BMD) were found in these rats. The numbers of TRAP-positive cells were increased at 12 weeks, while the numbers of osteocalcin-expressing cells were increased at both 12 and 32 weeks. Levels of mRNA expression of TRAP and cathepsin K were increased at 12 weeks, while levels of ALP and osteocalcin were increased at both 12 and 32 weeks. These findings demonstrated that there is an active bone remodeling in subchondral bone in TMJs in response to alteration in occlusion, although new bone was formed with lower BMD and poor mechanical properties.

OBJECTIVE: The effect of experimental jaw-muscle pain and stress on masticatory muscle activity in TMD-patients has been discussed. Furthermore, associations between TMD and deep bite patients have been studied. Accordingly in the present study, comparison of EMG responses at rest, maximal clenching, during evoked pain and stress between deep bite patients and controls was investigated.
DESIGN: In 30 deep bite patients and in 30 sex-/age-matched controls with neutral occlusion EMG activity was recorded bilaterally from masseter and anterior temporalis muscles before and during evoked pain and before and during a stress task. Evoked pain was induced by injections of glutamate into the masseter (local pain) and brachioradialis (remote pain) muscles and resting EMG activity was recorded before and after 1, 2, 3, 4, 5 and 10min. A precision task was used to simulate a stressful condition and EMG activity was recorded twice during the task. Maximal EMG activity was recorded during maximal clenching.
RESULTS: Resting and maximal EMG activity were significantly different between groups and age with no gender differences. EMG activity during local pain and during the precision task were significantly different between groups, gender, age and time, whereas no time effect was found for the EMG activity during remote pain.
CONCLUSIONS: Patients with deep bite have significantly different jaw motor responses to painful stimulation of the trigeminal region and manual precision tasks suggesting a differential integration of both somatosensory and behavioural stimuli.

65. Three-dimensional computed tomographic analysis of changes to the external features of the nose after surgically assisted rapid maxillary expansion and orthodontic treatment: A prospective longitudinal study
American Journal of Orthodontics & Dentofacial Orthopedics
Volume 144, Issue 3 , Pages 404-413, September 2013
The aim of this prospective, longitudinal study was to evaluate changes to the external shape and form of the nose after surgically assisted rapid maxillary expansion and orthodontic treatment. The changes were registered using a 3-dimensional computer tomography technique, based on superimposition on the anterior base of the skull.
The subjects comprised 35 patients (mean age, 19.7 years; range, 16.1-43.9 years). Low-dose, helical computerized tomography images were taken at treatment start and after orthodontic treatment, about 18 months postsurgery. The 3-dimensional models were registered and superimposed on the anterior cranial base.
There were in general significant widening and overall anterior and inferior displacement of the nasal soft tissues. The changes varied in size and direction. No correlation was found between the initial and final widths of the nose, or between the initial and final widths of the nostrils.
After surgically assisted rapid maxillary expansion, the most obvious changes to the external features of the nose were at the most lateral alar bases. The difference in lateral displacement profoundly influenced the perception of a more rounded nose. Patients with narrow and constrained nostrils can benefit from these changes. The 3-dimensional superimposition applied in this study is a reliable method, circumventing projection and measurement errors.

The aim of this study was to assess the existence of myofunctional alterations before and after first premolar extraction in Class II/1 malocclusion patients that could endanger the long-term dental arch stability.
MATERIAL AND METHODS:
The study was performed by means of morphological, functional and electromyographic analyses in 17 Class II/1 malocclusion patients (group T) and 17 Class I malocclusion patients (group C), both groups with 12-30-year age range (mean age: 20.93 +/- 4.94 years).
Data analyzed statistically by Student’s t-test showed a significant decrease in the maxillary and mandibular dental arch perimeters after orthodontic treatment (p<0.05). The Kruskal-Wallis test analyzed data from tongue posture at rest and during swallowing, not showing significant differences after treatment (groups Tb and Ta) (p>0.05). However, group T differed significantly from group C (p<0.05). The electromyographic data showed that the anterior right and left suprahyoid muscles acted synergistically in both groups, while having a lower myoelectric activity in group T during swallowing.
Myofunctional alterations observed after the orthodontic treatment in Class II/1 malocclusion seemed to jeopardize the long-term orthodontic stability, making recurrence possible. Further research should be conducted to compare electromyographic data before and after orthodontic treatment in order to corroborate the results of the present investigation.
