Summary
Victorian dentists often chose operative treatment for early enamel dental caries based on radiographs. However, evidence suggests many such lesions are not cavitated, highlighting a need for updated caries management education.
Area of Science:
- Dentistry
- Radiology
- Evidence-based practice
Background:
- Bitewing radiography is a common adjunct to clinical examination for dental caries.
- Treatment planning decisions based on radiographic findings are crucial in caries management.
Purpose of the Study:
- To investigate treatment planning decisions made by Victorian dentists.
- To analyze responses to predetermined radiographic scenarios of dental caries.
Main Methods:
- A postal survey was distributed to 550 dentists in Victoria.
- Systematic sampling was employed using the Dental Board of Victoria register (1996).
Main Results:
- The survey achieved a 64% response rate.
- 50% of responding dentists opted for operative intervention for lesions limited to enamel on radiographs.
Conclusions:
- The study's findings contrast with current literature, where many enamel-confined radiolucencies are non-cavitated.
- There is a clear need for continuing education programs in dental caries management, emphasizing evidence-based approaches.
