B. Searching by Keyword

Let's say we're interested in atraumatic restorative treatment. We type this and check "Map Term to Subject Heading":

Ovid attempts to map this to a Subject Heading:

Ovid is offering a number of suggested Subject Headings. But we can see that Ovid isn't at all confident that any of them is right (this time it has NOT checked a box in the "Select" column, i.e. it hasn't given us a hint about what to select).

So, we read over the suggested Subject Headings. (And if we need more information, we can check their scope notes by clicking .)

We conclude that while these Subject Headings may be related to our topic, none of them accurately describes our topic. E.g., Dental Restoration, Permanent is way too general -- if we selected this, we'd get thousands of articles that have nothing to do with atraumatic restorative treatment.

So our only option is to do a Keyword search for our term, by checking the box:

After clicking

we see our results (71 articles):

Our 71 articles include, for example:

• "Survival of glass ionomer restorations placed in primary molars using atraumatic restorative treatment (ART)..."
  (We found this because the title contained our Keywords.)

• "Clinical, histological and microbiological study of hand-excavated carious dentine in extracted permanent teeth"
  (We found this because the abstract contained our Keywords, in the sentence "Thirty-five extracted permanent molar teeth with an occlusal caries lesion were excavated with hand instruments according to the atraumatic restorative treatment (ART) approach.")

The tricky thing with Keyword searches is that we need to figure out what other terms the authors might have used for the same topic. For instance, some authors use the term "atraumatic restorative technique", so we would need to do a Keyword search for this term as well:
