Summary
Avian eggshell slurry effectively occludes dentinal tubules, offering a promising alternative for treating dentin hypersensitivity. This natural agent shows comparable efficacy to commercial desensitizing treatments.
Area of Science:
- Biomaterials Science
- Dental Materials Research
- Nanotechnology in Dentistry
Background:
- Dentin hypersensitivity is a common dental condition characterized by sharp pain.
- Current treatments include agents that occlude dentinal tubules to reduce stimuli transmission.
- Novel biomaterials are being explored for effective and accessible dentin desensitization.
Purpose of the Study:
- To evaluate the efficacy of avian eggshell slurry as a novel desensitizing agent.
- To compare its tubule occlusion and permeability reduction with a commercial product, Tooth Mousse (containing casein phosphopeptide-amorphous calcium phosphate - CPP-ACP).
Main Methods:
- Eggshell powder was characterized using SEM, TEM, XRD, and EDX.
- Dentin disks were acid-etched to simulate hypersensitivity.
- Treated disks were immersed in artificial saliva or subjected to acid challenge.
- Environmental SEM (ESEM) and hydraulic conductance tests assessed tubule occlusion and permeability.
Main Results:
- Avian eggshell slurry demonstrated a significantly higher percentage of dentinal tubule occlusion compared to Tooth Mousse.
- No significant difference in dentin permeability reduction was observed between groups after acid challenge.
- Tooth Mousse showed a greater reduction in dentin permeability after artificial saliva immersion.
Conclusions:
- Avian eggshell slurry is an effective agent for occluding open dentinal tubules.
- It presents a promising, potentially natural, material for managing dentin hypersensitivity.
