This is the first study to report the prevalence of
tori in edentulous patients in Jordan. The results
showed a high prevalence of tori (13.9%). This
is higher than what has been found in earlier
reported studies; 12.3% in Trinidad and Tobago
West Indies1
, 6.6% in Jamaican Blacks14, but
less than the prevalence reported in a Ghanaian
community (14.6%).
24 However, the present
study did not show any significant difference in
the prevalence of either palatal or mandibular
tori between males and females implying the sex
based factor has little influence on the prevalence
of tori. This is in contrast to a Norwegian study15
and other studies2,5,12,16,18,20
, which demonstrated
males had a higher ratio to females for tori.
Haugen30 suggested genetics as the responsible
factor for the difference, while Alvesalo31
suggested sexual dimorphism in the manifestation
of torus mandibularis might result from the
effect of Y chromosome on growth, occurrence,
expression, and timing of development of
mandibular tori. Similarly, there was no significant
difference in the prevalence between mandibular
(9%) and palatal tori (7%) (p>0.05).
The high prevalence of tori among the 81-90
years age group in our study should not be
considered very important because the sample of
that age group is small and might not reflect the
true prevalence. A larger sample size is needed
for future studies. The results of the present
study are in disagreement with Choyayeb and
Volpe25
who found no relationship between age
and the presence of tori in either jaw.
The role of nutrients in the etiology of tori has
been recently reviewed by Eggen et al.
15 who
suggested saltwater fish consumption in Norway
possibly supplies higher levels of polyunsaturated
fatty acids and Vitamin D that is involved in
bone growth which increases the chances of
tori. Also it has been reported genetic and
dietary factors may be involved in the etiology
and variation in the prevalence of tori. For the
time being, genetic factors are the probable
culprits in the occurrence of tori in Jordan as fish
