This study investigated the subjective symptoms of craniomandibular di
sorder and the restriction in maximal mandibular opening of 891 elderl
y Singaporean citizens. A distribution of 22% of subjects (20% of the
women and 26% of the men) reported subjective symptoms of craniomandib
ular disorders. The most common single symptom reported was occasional
to frequent clicking sounds from the temporomandibular joints (in 15%
of subjects). The other single symptoms were reported only occasional
ly in 2-6% of subjects. Nineteen per cent of the subjects had some res
triction in maximal interincisal opening (30-39 mm) and about 1% of su
bjects were severely restricted in maximal opening (less than 30 mm).
Subjectively evaluated limitation of wide mandibular opening was recor
ded for only 2% of the subjects. Background factors included general m
usculo-skeletal problems (54%), perceived fair to poor general health
(29%), headaches (33%), work-related stress (24%), oral parafunctional
clenching (4%) and grinding activity (4%). This paper confirms earlie
r reports that the subjective signs and symptoms of craniomandibular d
isorder tend to diminish in elderly people.
