Abstract
Sialolithiasis is largely a disease of adults, and
there is a 2:1 male sex predilection. However, there are
several reports of salivary calculi in infants and child-
ren (Burdel et al., 1970).
The left side is said to be more frequently affected
than the right (Tourneux et al., 1970). And rarely there
is bilateral involvemento Multiple occurrences of sali-
vary calculi in the same gland. However, are quite
common. The submandibular gland contains two calculi in
approximately 20% of the patients and more than two in 5%
(Noehoe n , 1970).
The calculi generally round or oval and is yellowish
but may be vary from white to tan. The consistency ranges
from soft to stony hard. In general the salivary duct
calculus is hard, whereas peripheral salivary calculi is
soft (Rauch and g cr-Li.n , 1970).
Salivary calculi were formed by a laminated mL~ture
of inorganic and organic substance. However, there was no
regular pattern for the growth of stones, as laminal
thickness and the arrangment of the laminal component were
not uniform (Harril, 1959).
