Corrosion in the oral cavity--potential local and systemic effects
International Dental Journal
|March 1, 1986
Summary
Oral galvanic cells, like bimetallic and concentration cells, generate currents. Clinical studies suggest these currents may correlate with patient symptoms, questioning the value of in vitro corrosion tests.
Area of Science:
- Oral medicine
- Biomaterials science
- Electrochemistry
Background:
- Oral cavity hosts bimetallic and concentration cells causing corrosion.
- Corrosion resistance depends on environmental interaction, not intrinsic properties.
- In vitro corrosion tests have limited predictive value for clinical behavior.
Purpose of the Study:
- To investigate the relationship between galvanic currents and patient symptoms.
- To discuss potential local and systemic effects of intra-oral galvanic cells.
Main Methods:
- Clinical studies involving patients referred to the Faculty of Odontology.
- Brief presentation of results concerning galvanic currents and symptoms.
Main Results:
- Galvanic currents are generated by oral corrosion cells.
- Potential correlation between galvanic currents and oral/other symptoms observed in a patient group.
Conclusions:
- Intra-oral galvanic cells may have local and systemic effects.
- Clinical relevance of oral corrosion needs further investigation beyond in vitro testing.
