Abstract
Temporomandibular disorders are
often defined on the basis of signs and symptoms, of which the most common are:
temporomandibular joint sounds, impaired movement of the mandible, limitation
in mouth opening, preauricular pain, facial pain, headaches and jaw tenderness
on function, having mainly a mild character, fluctuation and progression to
severe pain and dysfunction is rare. One of the possible causal factors
suggested that temporomandibular disorders is a functional mandibular overload
variable, mainly bruxism. Bruxism, defined as the habitual nonfunctional
forceful contact between occlusal tooth surfaces, is involuntary, excessive
grinding, clenching or rubbing of teeth during nonfunctional movements of the
masticatory system. Its etiology is still controversial but the multifactorial
cause has been attributed, including pathophysiologic, psychologic and
morphologic factors. Moreover, in younger children, bruxism may be a
consequence of the masticatory neuromuscular system immaturity. Complications
include dental attrition, headaches, temporomandibular disorders and
masticatory muscle soreness. This paper aimed to explain the effect of bruxism to
temporomandibular disorder.
Key words : bruxism,
