Sir, working for a couple of years and coming across various exam templates and attending dental legal courses I have seen the emphasis on the title 'caries risk'. I have recently come across a colleague who has been legally challenged as he incorrectly categorised a patient as moderate caries risk when they should have been in the high caries risk category.

Is there any official parameter for low/medium/high risk? As I am under the perception that when there are lesions of more than nine, high sugar intake and living in a low fluoridated area we should place the patient under a high caries risk with a three-month recall and the use of high fluoridated toothpaste. But what about those patients with nine or more lesions but who live in fluoridated areas and have reduced their sugar intake?
