Interpretation of base-metal dentinal radiopacities: survey results

A survey was conducted to determine the familiarity with base metal dentinal radiopacity. The results show that although 91% of the respondents had observed this phenomenon, only 6% could correctly identify its cause. Despite the general misunderstanding concerning its cause, 48% of the respondents considered this radiopacity when making a diagnosis and providing treatment. To limit confusion, a standard term is suggested so this feature can be more consistently identified and properly considered in making diagnoses and in formulating treatment plans.
