Although this activity may be closely related to muscle pain, the association may be difficult to identify, since most patients are unaware of their bruxing or clenching activities.
This will discourage bruxing activities and minimize the load on the teeth and joints.
People with neurological and neuromuscular disorders, such as cerebral palsy, mental retardation and closed head injuries are prone to salivary incontinence (drooling), and severe bruxing
(tooth grinding) habits that may result in excessive wear of teeth and injury to the temporomandibular joint (Richmond, Rugh, Dolfi, et al., 1984).
Heavy occlusal forces: Ceramic restorations may fracture when they lack bulk or are subjected to excessive occlusal stress, as in patients who have bruxing
or clenching habits.
Medical history of potential oral symptoms associated with GERD was carefully collected and the following parameters was evalu- ated; brushing method, dental erosion, dental sensitivity, loss of dental structure because of abnormal attrition (clenching or bruxing
of one tooth surface against another), physical wear by extraneous objects such as toothbrushes, also known as tooth abrasion, alteration of the mucosa.
