IBM Watson Assistant: Chatbot for dental tooth status acquisition, tooth position as entity or intent?

Question

We want to ask the patient for the dental status. The patient would ask

I need an implant for the right front tooth.

We have to assign this to a tooth number. In the numbering scheme it would be tooth 11, with entity implant.

Question, should we handle the 32 teeth as intents or as entities?

The patient would not be able to give the tooth position in numbers, would take some questions to define the tooth position with the IBM Watson Assistant chatbot. As I am unsure about the answers intents would be more suited, to define an individual tooth position?

Below the schema and number for teeth. https://en.wikipedia.org/wiki/Dental_notation

        upper right - 1             upper left - 2
    18 17 16 15 14 13 12 11 | 21 22 23 24 25 26 27 28 
 R --------------------------------------------------- L
    48 47 46 45 44 43 42 41 | 31 32 33 34 35 36 37 38 
        lower right - 4             lower left - 3 


 I - incisor
 C - canine
 P - premolar
 M - molar

Answer 1

So this sort of problem is solved easier with a custom mini-form within the chat. For example an interactive row of teeth they can click on.

Answer 2

See this overview about IBM Watson Assistant implementation steps for what makes an intent or entity. The intent is for the goal the user wants to achieve, entities identify objects and provide the processing context.

With that, in your scenario the intent is to identify teeth (intent), but you would do so by individual position or region (entity), right?

You could present a list of options to the user. Which region? Provide four to click or select. Which tooth? Label them for selection. This is kind of a guided selection.
