In short, yes.
I have seen cases where N-400 naturalization applications were denied because of a DUI or alcohol related offense, even if there was not what was considered a conviction under criminal law.
If the cases was dismissed, there may be less chance of it being an issue, but note that an expungement does not necessarily mean it is not seen as a conviction for immigration purposes.
In general, a naturalization applicant must show s/he meets the good moral character criteria for the last 5 years. Even w/o a conviction or a crime that is not considered a CIMT, an individual could be denied based on good moral character grounds.
You should have your matter reviewed by an experienced immigration attorney who can analyze:
1) Does this incident affect any removability ecesis?
2) Does this incident affect any admissibility issues?
3) Does the incident affect naturalization eligibility?
How each answer on the N-400 needs to be answered depends on the specific disposition of your case.
