General Information:

The section of function & dysfunction of the stomatognathic system deals with the following aspects of the dental profession:

  • Dental morphology
  • Physiology of the masticatory system and occlusion
  • Temporo-Mandibular Disorders (TMD)
  • Oro Facial Pain (OFP)
  • Oral treatment of obstructive sleep apnea


  • Ephraim Winocur, DMD, lecturer, in charge of the section and the clinic
  • Alona Perlman-Emodi, DMD
  • Reiter Shoshana, DMD
  • Albert Mansour, DMD
    Carole Goldsmith DMD
  • David Cohen, DMD
  • Ms. Nira Orgil, Dental Assistant


Teaching Activities:

A. Undergraduate level:

The undergraduate level consists of 6 courses given to dental students in the 3rd-6th years of their dental studies. All the courses are coordinated by Dr. Ephraim Winocur. The courses are:

  • Dental morphology of the permanent dentition (3rd year): the course deals with the anatomy of the individual teeth with special emphasis to the relationship between the form of the teeth and its function.
  • Physiology of the masticatory system and occlusion (4th year): the course lays out the foundation for the understanding of the integrated function of the masticatory system. Special consideration is given to the high degree of harmony needed between the components of the masticatory system in order to function normally and efficiently.
  • Temporo-Mandibular Disorders (5th-6th years): The mayor objective is to provide the student guidelines for classification, assessment and management of TMD.

•   ·   Multidisciplinary Course on Orofacial Pain (6th year): the course is designed to provide an insight to pain conditions associated with the orofacial area with special emphasis to pain felt in the dentition but originating in extra oral structures. It deals with the neurologic mechanisms underlying the various aspects of acute and chronic pain.

B. Graduate level:

The section is involved in the teaching of selected topics on temporo-mandibular disorders and occlusion and patient management to residents from various clinical disciplines.


C. Post-graduate level:

The department runs a 2 academic years (450 hours) post-graduate course for dentists on occlusion, temporo-mandibular disorders and orofacial pain.

Clinical Activities:

Within its activities, the section operates a specialist clinic as follows:


The Clinic for Orofacial Pain & Temporo-Mandibular Disorders:

Dentist in charge: Dr. Ephraim Winocur

Operating Faculty:  Dr. Alona Perlma-Emodi, Dr. Shoshana Reiter, Dr Albert Mansour, Dr. Carole Goldsmith, Dr. David Cohen, Ms. Nira Orgil (Dental Assistant)

Clinical Activity: The clinic deals with the evaluation, diagnosis and treatment of patients suffering from pain felt in extra oral structures (masticatory musculature, cervical region, temporomandibular joints, etc.), as well as intra oral pain referred from extra oral areas (muscles, joints, neck, cranial nerves, etc.). The clinic also deals with not painful temporo-mandibular disorders (disc displacements, subluxations, bruxism, etc.). Patients suffering from mild obstructive sleep apnea are referred to the clinic in order to be treated with oral appliances. The treatment is multidisciplinary. Patients are referred by dentists and physicians all over the country.  Sixth year students are present during the process of diagnosing and managing the patient.


Research Activities:

 The main research interests of the department include:

  • Oral parafunctions and its association with TMD
  • The Bruxism phenomenon
  • Intra oral appliances for obstructive sleep apnea.
  • Therapeutics approaches for the treatment of temporo-mandibular disorders.
  • Hypnosis and hypno-relaxation as a treatment for temporo-mandibular disorders.
  • Epidemiological studies concerning functional disorders of the mandibular system
  • Dental morphology and anthropology
  • Gender differences in pain.
