What the record tells you
William B. Sproul, D.M.D., P.C. is an NPI registry record for a dental organization at 51 Santa Clara Ave in Eugene, Oregon 97404. CMS issued NPI 1255492047 on 13 December 2006, and the practice last updated its own entry on 22 August 2020. That was 6 years ago, so treat the phone number and the suite number as unconfirmed until someone answers.
It is registered under 2 dental taxonomy codes: General practice dentistry (1223G0001X), Dental clinic or center (261QD0000X). That puts it in 2 categories on this site, led by general dentistry. A practice that registers more than one category is telling CMS it does more than one kind of dental work at this address, which is why it has a page here rather than a row. No other address in the registry carries this name, though a practice trading under a chain brand often registers each office under its own legal name, so check the brand as well. One further NPI is registered to what looks like the same business at this address (Sonja A. Sproul, D.D.S., P.C., NPI 1336575273); it is covered by this page rather than given a page of their own. 2 other dental records share the street address: Howard F. Curtis and Dr. Shawn Eckstrom, D.D.S., P.C..
Eugene holds 95 registered dental practices inside the Eugene-Springfield, OR area, which has 139 in total on the Oregon side and ranks 3rd in the state. 57 of the Eugene records also register general dentistry, so this is one of several local options in that category. Across the metro the mix runs general dentistry 63.3%, dental clinic or center 19.4%, pediatric dentistry 8.6%. The closest other registered practices are Howard F. Curtis (0 miles, Eugene), Dr. Shawn Eckstrom, D.D.S., P.C. (0 miles, Eugene) and Distinctivedentistry (0.6 miles, Eugene), with 2 more inside 1.4 miles.
On our figures a routine adult cleaning in Oregon runs $115 to $170 cash and scaling and root planing $185 to $285 per quadrant, against a US average of $125. This practice's own prices are not in the registry and never will be: NPPES holds identifiers, not fees. Call (541) 689-2001 and ask for the cash price on code D1110, whether the exam and X-rays are included, and whether they run a membership plan if you have no insurance.

What to ask when you call
- The cash price for D1110, a routine adult cleaning, and whether the exam (D0120) and X-rays (D0274) are inside or outside that number.
- Whether you need scaling and root planing before a routine clean, and the per-quadrant price for D4341 or D4342 if so.
- Whether they run an in-house membership plan, and what it covers against what it costs a year.
- Whether they are taking new patients and how far out the next hygiene appointment is.
- The practice license, with your state dental board. An NPI is a billing identifier and proves nothing about licensing.
CMS NPPES NPI data file, August 2026, snapshot 10 August 2026. US federal public data (FOIA-disclosable, no charge). CMS NPI files. NPI registry records, status as reported by CMS in the August 2026 data dissemination file. NPPES is an identifier registry, not a license register: an NPI does not validate that a practice is licensed, accredited or currently open. Practices maintain their own NPPES entries. Every page shows the date the record was last updated; addresses and phone numbers are as self-reported and are not verified by us. This page describes a registry record.

Price figures are our own, last verified April 2026. State averages are our estimates compiled from FAIR Health regional cost data and CMS Medicare fee schedules; the ADA discontinued its national Survey of Dental Fees in 2023, so no national fee survey exists.
