To answer your question specifically, please refer to the following journal article: https://journals.asm.org/doi/10.1128/iai.00338-08#:~:text=Streptococcus%20sanguinis%20is%20one%20of,species%20implicated%20in%20infective%20endocarditis. “Streptococcus sanguinis is one of the pioneers in the bacterial colonization of teeth and is one of the most abundant species in the oral biofilm called dental plaque. S. sanguinis is also the most common viridans group streptococcal species implicated in infective endocarditis.”

Sorry for jumping the gun there; in the future, we need more context on what the UWorld question is about in your rationale. Review submission guidelines for sourcing here: Notion – The all-in-one workspace for your notes, tasks, wikis, and databases.
Your rationale here helped us so much more, thank you!
Don’t support addition here. None of these sources say they cause dental caries as this question asks, just that it is present on dental plaque and causes IE
@Cameron, “If the plaque is allowed to build up, the acid can begin to break down (dissolve) the surface of your tooth, causing holes known as cavities.” Tooth decay | NHS inform).
I am a little bit confused where the line is drawn between causing dental plaques vs. causing dental caries since plaques typically precede the development of dental caries. I will admit teeth are not my forte, perhaps you could cite a source? I’d love to learn more.
I’m going based off boards resources. AMBOSS and First Aid pg 134 specifically points out mutans and mitis causing caries but leaves out sanguinis. For boards those ones are likely most relevant
Again, I reference the UWorld question #3014. How does this card add any benefit in preparing students for that question/concept? Neither mitis nor mutans were answer options.
That question doesn’t have to do with dental caries specifically, just infective endocarditis following dental manipulation. Additions to the other two cards will be more than enough for people to get that one right
this information is highlighted in the extra section of this nid: 1472072097648
agree with CTE, this is specifically dental caries, not IE
I think we have 2 discussions going on here. Per UTD: “An etiologic association of S. mutans in dental caries has been firmly established . S. mutans is the only organism consistently isolated from all decayed dental fissures and is the only organism consistently found in greater numbers in carious teeth than in noncarious teeth.” Per AMBOSS and UTD I do not see anything to suggest that sanguinis is involved in dental carriers. I believe the confusion comes from the fact that sanguinis colonizes the tooth surface and can cause infections whenever there is a dental procedure. I think this should be added to the extra but I now disagree with the edit suggestion in its current form.
@doc nuggets I can see where you are coming from. You bring up a great point here and I am going to edit your suggestion to cover all the bases.
@Aaron, I appreciate the clarification and learning point. Based on what you said, then perhaps the card should be edited to reflect only “S. mutans.”
