Background:
The most common adjunct to the visual and tactile clinical examination for dental caries is the bitewing radiograph. The aim of this study was to report on treatment planning decisions made by Victorian dentists when given a range of predetermined radiographic scenarios.
Methods:
A postal survey was conducted to obtain data from 550 dentists selected systematically (every fourth dentist) from the register of the Dental Board of Victoria (1996).
Results:
The survey response rate was 64 per cent. Fifty per cent of responding dentists selected an operative intervention for radiographic lesions confined to enamel.
Conclusions:
A review of current dental literature does not support this approach because a large proportion of proximal tooth surfaces that have associated radiolucencies confined to enamel are not cavitated. This study supports the need for continuing education programmes on the management of dental caries; such programmes should follow an evidence-based model.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
