The incidence of masticatory dysfunction and its relation to the masticatory myalgia syndrome.
840 people were included in this study. 29.2% of them were found to have at least two dysfunctional signs, either in combination with pain (7.2%) or without pain (22%). The former group represents cases of the masticatory myalgia syndrome, while the later (the non-painful masticatory dysfunction group) may be considered as representing a pre-clinical stage of the masticatory myalgia syndrome.
