2 potential causes of sialolithiasis
Chronic sialadenitis (viral/bacterial), Partial duct obstruction
Are sialolithiasis hard or soft?
Hard
___% of sialolithiasis come from the ____ gland
80%, submandibular
Radiographic sialolithiasis feature
Opaque, lamellated structure
Histologically: sialolithiasis shows concentric ____ surrounding ____
Laminations, debris
Sialolithiasis may demonstrate ____ ____ if the duct is removed

Treatment for sialolithiasis
Increase saliva, moist heat, massage, removal of gland
Prognosis for sialolithiasis
Good for minor glands. Morbidity if major gland requires removal
Disorder: Inflammation of the salivary gland
Acute/Chronic Sialadenitis
Causes of Sialadenitis
Bacterial, Viral, Ductal obstruction/retrograde infection
Cause of bacterial Sialadenitis

Cause of viral Sialadenitis
Mumps
Cause of ductal obstruction/retrograde infection leading to Sialadenitis
Xerostomia, may follow general anesthesia
Chronic Sialadenitis may follow acute Sialadenitis due to ___ damage
Ductal
Difference in Sialadenitis in Sialolithiasis
Sialadenitis is diffuse and sialolithiasis is localized
Is Sialadenitis painful?
Yes (note: it’s INFLAMMATION)
