This document discusses the management of postoperative root dentin hypersensitivity, characterized by short, sharp pain due to exposed dentin. It outlines various causes, locations, theories of pain, and recommended desensitizing agents used both at home and in-office. The document emphasizes that this condition is related to open tubules and is challenging to treat, with symptoms that usually diminish after the first week.

1. MANAGEMENT
OF
POSTOPERATIVE
(ROOT)
SENSITIVITY

2. ROOT DENTIN HYPERSENSITIVITY
• Exaggerated response to non noxious stimuli
• Short, sharp pain from exposed dentin Thermal, chemical &
tactile sensation
• AS A RESULT OF:
1. Denuded root surface
2. Post SRP Procedure
3. Periodontal pockets
4. Post periodontal surgeries
5. Faulty brushing

3. AREA OF OCCURRENCE:
Cervical area of the root as the cementum is extremely thin.
THEORIES :
1. Hydrodynamic theory
2. Odontoblastic theory
3. Neural theory

4. MANAGEMENT ?

5. WHAT do we use – DESENSITIZING AGENTS?
IN HOME AGENTS - DENTRIFICES
• Sensodyne
• Thermodent
• Protect
• Promise+
• Colgate sensitive
• Mcleans sensitive
IN HOME IN OFFICE
CONTAINS: Potassium nitrate, sodium monofluorophosphate, sodium
citrate, , strontium chloride, dicalcium phosphate.

6. IN OFFICE AGENTS:
Cavity varnish
Composite resin
Dentin bonding agents
Oxalates – Potassium oxalate
Fluorides – NaF, SnF.
Iontophoresis
Laser – Nd:YAG
OTHERS:
Gingial graft surgery
Pulpectomy
Extraction
# DIETARY COUNSELLING

7. HOW does it act on tooth?
DENTRIFIC ES:
• It acts through the precipitation of crystalline salts on the dentin
• Complete occlusion of the dentinal tubules
• Produce a coagulant effect on tubular content
BONDING AGENT & VARNISH:
• Seal out the dentinal tubules
IONTOPHORESIS:
• Transfer of desensitizing agents into the tooth under electric pressure
BURNISHING:
• Formation of smear layer produced by burnishing of the exposed surface

8. DIETARY COUNSELLING:
To control the frequency and quantity of ACID intake
CLINICAL TIPS:
To avoid hard bristled tooth brush
To avoid over brushing and flossing
To avoid brushing immediately after consumption of acidic foods

9. CONCLUSION
Thus root dentin hypersensitivity is clearly related to open tubules
which is difficult to treat and sometimes frequently developed. The
symptoms usually evoked during first week and then subsides in the
subsequent weeks..
