PubMed: MeSH: Why MeSH?
Why use MeSH?PubMed’s easy search interface
makes assumptions about what you want, and interprets what you search
Using MeSH makes your search more precise and specific, meaning you are more likely to get what you really want
Using MeSH provides consistency and control
PubMed: MeSH: Why MeSH?
Assumptions:Example:
Root canal perforation(200 results)
PubMed: MeSH: Why MeSH?
Assumptions:Example:
Root canal perforations(196 results)
PubMed: MeSH: Why MeSH?
Assumptions: Example: Root canal perforations“Root canal” became “dental pulp cavity”
Did you mean the anatomical area, or the procedure?
Perforations or perforation retrieved different results -- PubMed did not automatically pluralize.
Just when you assume it assumes what you assume, it doesn’t …

Full entry for Dental Caries
PubMed: MeSH Database: Entry Terms
MeSH term is equivalent towords and phraseslisted as“Entry Terms”
These terms,when appearingin an abstract,will result in thisMeSH term beingassigned.
PubMed: MeSH Database: Cross References
MeSH entry will also provide “See Also” terms.
These suggest alternate MeSH terms that you may wish to use instead of or in addition to the term currently selected.
PubMed: MeSH Database: Tree Display
Here is your first real clue that “Tooth Demineralization” should usually be used for searching “Caries”.
PubMed: MeSH Database: Send to Search
From MeSH Browser, you can send selections directly to the Search box.
Use the “Send-to”drop-downmenu on the far right.
PubMed: MeSH Database: Send to Search 2
PubMed: MeSH Database: Send to Search 3
See result in expert search form in the Search Box.
Click “Search PubMed”
PubMed: Clinical Queries
What Clinical Queries do for you:FastFocused (not too many articles)High-Quality (original research)
This means you make a clinical decision or recommendation without having to dig through many citations looking for the “good stuff”
