Summary
Sensitive dentine, often caused by exposed tubules, is linked to physical and chemical factors. Understanding these causes is key to managing dentine hypersensitivity effectively.
Area of Science:
- Dentistry
- Oral Biology
- Biomedical Science
Background:
- The hydrodynamic theory suggests dentine hypersensitivity arises from open dentinal tubules.
- Dentine exposure occurs through loss of enamel or periodontal tissues (gingival recession).
- Chronic physical and chemical trauma are identified as significant etiological factors in exposed cervical dentine.
Purpose of the Study:
- To explore the etiological factors contributing to dentine hypersensitivity.
- To emphasize the need for enhanced understanding to develop effective management strategies.
Main Methods:
- Review of epidemiological and clinical data on exposed cervical dentine.
- Consideration of evidence supporting the hydrodynamic theory of stimulus transmission.
- Analysis of the potential effects of toothpaste ingredients on dentinal tubules.
Main Results:
- Evidence supports the presence of open dentinal tubules in sensitive dentine.
- Erosion is highlighted as a probable primary cause of dentinal tubule exposure and sensitivity.
- Toothpaste application may form a smear layer rather than opening tubules.
Conclusions:
- Further research, including epidemiological studies, clinical investigations, and laboratory experiments, is crucial.
- A deeper understanding of etiological factors is essential for evolving sound management approaches to dentine hypersensitivity.
