I disagree with observation. Dave makes a good point and I should have used the word common or most common state rather than normal.
I am struggling to see how we would use this information to do anything but document a very common condition. If the overwhelming majority of the population has plaque on their teeth, I cannot see how we could develop any decision support or even correlations that would let us understand health better.
The remote, but possible, utility of an observable is that we might be able to eventually develop a scale to create smaller sets of the very large population and see if there is a difference in relationships to disorders. However, that is not my choice of approach either. Evaluate Confluence today. Dentistry Clinical Reference Group. Space shortcuts Discussions. Page tree. Browse pages. Remove Read Confirmation.

Roger Adams. Trying out the forum instead of e-mail Any thoughts? Permalink Dec A plural can be a child of a singular because: Multiple "Teeth" can be an instance of a singular "tooth", "teeth" IS-A "tooth" "Tooth" cannot be a instance of "teeth", a single "tooth" is not a multiple "teeth", "tooth IS NOT A "teeth" Jim has also suggested that we try and create a body structure of "Multiple teeth body structure " as a sibling of "Tooth structure" to take care of the situation that Jorn describes here.
Then we can see how this would play out in the hierarchy. And then set the "rules" Jorn. I'm not sure if this is what you are looking for Jorn: Concept ID Dental restoration failure of anatomical integrity regarding adjacent teeth Attribute value Tooth restoration failure finding Concept ID Diastema of teeth finding Attribute value Tooth structure body structure Concept ID Excessive spacing of fully erupted teeth finding Attribute value Tooth structure body structure Concept ID Finding of interincisal teeth angle finding Attribute value Finding of tooth angulation finding.
A plural can be a child of a singular. Can a singular be a child of a singular rephrasing Joel's definition during our call : "Tooth" can be an instance of a singular "tooth" Concept ID Tooth discolored finding Attribute value Finding of tooth color finding Further, Can a plural be a child of a plural again rephrasing Joel "Teeth" can be an instance of a multiple "Teeth" Concept ID On examination - discolored teeth finding Attribute value On examination - teeth examined finding.
Thank you Roger, these are just the kind of examples I'm looking for. When it comes to the "rules" I think you are right. Singular as a child of plural would then be out. Teeth is an irregular plural form. An adult human has 32 teeth. But whenever we are referring to individual structures, we use the word tooth. For example,. I brush my teeth every day. We often use the word teeth than tooth since we always refer to teeth collectively. It is only rarely that we refer to a single tooth.
Surprisingly, the terms do not only differ in terms of count of the teeth, but also when it comes to their usage. What are the actual differences, then? This term is usually used in its collective form.
For example, you should brush your teeth every day. In this case, you talk about the whole set of teeth and not just one tooth. Tooth , on the other hand, is the singular form of teeth. For example, you may need a filling in a decayed tooth, and not in all the teeth. One uses his teeth for chewing food. The difference between a tooth and teeth is in their count, although, there are many more dissimilarities between the two.
