Cysts of the oral cavity contain fluid filled in the cavities which varies in consistency, color and protein content which help in differentiating and diagnosis based on these findings. Aspiration of fluid is done with the help of needle and syringe.
Here we are going to list out the various Cysts of the Oral cavity and their Fluid Aspirates their consistency, color and other features:
Dentigerous cyst Aspirate:
- Aspirate is Clear, pale, straw colored fluid which contains “Cholesterol crystals” and the protein content is in excess of 4.0 gm per 100 ml
Odontogenic Keratocyst Aspirate:
Aspirate is Dirty, creamy white viscid suspension which is characteristic of OKC and also contains Parakeratinized squamous cells in the fluid. Total protein content in the fluid is less than 5 gm per 100 ml and most of the protein content is Albumin which is a less soluble protein.
Diagnosis of Oral Cystic Fluid on Aspiration:
Periodontal cysts Aspirate:
- Aspirate is clear, pale yellow straw colored fluid which contains Cholesterol crystals and the total protein content is 5 -11 gm per 100 ml for periodontal cysts
Solitary bone cyst Aspirate:
- Aspirate is serous or sanguineous fluid and may contain blood or empty cavity. The fluid also contains Necrotic blood clots which are characteristic of Solitary bone cyst.
Stafne’s bone cyst or idiopathic bone cavity Aspirate:
- It is a empty cavity without epithelial lining and filled only with air

Dermoid cyst Aspirate:
- Aspirate is a thick sebaceous material which is secreted by the sebaceous glands present in skin
Mucocele, Ranula and Fissural cyst Aspirate:
- Aspirate is Mucus fluid secreted by the salivary glands and accumulated due to different reasons for the 3 types.
Hemangioma Aspirate:
- Aspirate is fresh blood in the cavity as the name suggests
Arterial and Venous malformation Aspirate:
- Aspirate is bright red blood which shows pulsation movements and pushes plunger
These findings should be remembered to be able to diagnose any cyst which you might encounter in your practice. And aspiration of the fluid is as important as radio-graph for diagnosis of cysts.
thank you for sharing your knowledge with us. i want to know about aspirate of periapical cyst
Periapical Cyst Aspirate consists of – Albumin – 2.5 to 5g/dl, Globulin – 2 to 5 g/dl, Total Protein 5 to 11 g/dl
Hello there… Could somebody please solve my query?
Stafne’s bone cyst is a type of aberrant salivary gland tissue…
How then would it be an air filled cavity?
As you know, Stafne’s bone cyst is thought to be caused by Ectopic salivary gland, the remnants of the salivary gland are not seen at a later stage and it is seen that the Pseudo Cyst (Stafne’s bone cyst) does not have an epithelial lining as well because it is considered by some to be an anatomical defect due to the submandibular salivary gland and not pathological. The cavity of the cyst is empty without any fluids or any inflammatory matter and hence it is said to contain air.
Presence of air on aspiration is seen in which cyst?
Dentigerous cyst
Radicular
Calcifying odontogenic cyst
Incisive foramen cyst?
Pleas cn u give me the answer
Thankyou sir!
much help
Hello
Please i had a swelling on my gum on top of my baby tooth incisor .and the aspirate was colorless clear and liquid just like water . So I had an extraction of this tooth and 2 months latter another swelling showed up on the same position. The aspirate was again colorless. Since the aspirate is not straw yellow colored does this rule out or question the possibility of it being a dentigerous cyst
