common chair side investigations

1. What are the common chair side
investigations you can do for this
case?

2. (1) Pulp Vitality Test
• Electric Pulp Test
• Heat test (Heated Gutta Percha)
• Cold test (pellet with saturated ethyl chloride,
dry ice)

3. (2)Tissue Biopsy

5. The role of fine needle aspiration cytology/biopsy
(FNAC/FNAB) in the diagnostic evaluation of
neoplastic and non-neoplastic lesions has increased
dramatically. This safe, reliable, cost-effective and
easy procedure can eliminate the need for open
biopsy procedure, with its potential untoward effects.
The fundamental indication for FNAC is a lesional
mass that is palpable or visible by a radiological
imaging method. This technique may also assist in
establishing a specific diagnosis for radiolucent lesions
of the jaw. The thinning or destruction of cortical bone
permits the use of thin needles to aspirate such
abnormalities.

6. Interpret the radiographic lesion
seen in relation to lower right
second deciduous molar

8. (Location)
• Unilocular radiolucency area on
- root apex of 85,
- Encovering the entire tooth structure of 45
- Encovering the entire tooth structure of 47

9. (Periphery)
• Well defined corticated border

10. (Internal Structure)
• Total Radiolucent surrounding the unerupted
45, 47

11. (Effect on surrounding structures)
• Thinning of trabeculae
• Inferior Alveolar Canal displaced inferiorly
