Kenneth R. Satchjen, D.D.S.
Surrenders Dental License

Stephen Barrett, M.D.

In 2005, the Wisconsin Dentistry Examining Board accepted the permanent surrender of the license of Kenneth R. Satchjen, D.D.S., of Madison, Wisconsin to settle charges that he had improperly treated a patient. The settlement order states that in 1998 and 2001, without doing a thorough examination, he had performed a total of six root canal treatments using a modified version of Sargenti technique and that the patient wound up with "a fractured bridge, crowns with severe overhangs, and several root canals that were poorly done and incomplete." The Sargenti technique uses a filler that is potentially toxic to tissues that surround the tooth.







[Division of Enforcement Case # 02 DEN 053]

The parties to this action for the purposes of Wis. Stat. § 227.53 are:

Kenneth R. Sachtjen, DDS
1603 Monroe Street
Madison, WI 53711

Division of Enforcement
Department of Regulation and Licensing

Dentistry Examining Board

Madison, WI 53708-8935


The parties in this matter agree to the terms and conditions of the attached Stipulation as the final decision of this matter, subject to the approval of the Dentistry Examining Board. The Board has reviewed the attached Stipulation and considers it acceptable.

Accordingly, the Board in this matter adopts the attached Stipulation and makes the following:


1. Kenneth R. Sachtjen, DDS, Respondent, (DOB 12/20/49) is duly licensed to practice dentistry in the state of Wisconsin (license #5001534). This license was first granted on 07/18/1975.

2. Respondent’s most recent address on file with the Wisconsin Dentistry Examining Board is 1603 Monroe Street, Madison, WI 53711.

3. At all times relevant to this proceeding, Respondent was practicing as a dentist in Madison, Wisconsin.

4. Between September 4, 1998 and September 14, 1998, J.J. went to Respondent’s office to have bridge work tightened. Without taking any x-rays and without performing a thorough examination of J.J.’s teeth, Respondent told J.J. that root canals were needed on all four abutment teeth before J.J.’s bridge could be placed back on them. Over the course of two visits, Respondent did the root canals and bridgework on J.J. Respondent charged J.J. $7,000 for the work.

5. Between March and May of 2001, J.J. went back to see Respondent. Respondent determined, without an examination of J.J.’s teeth, that J.J. needed to have crowns and root canals on two teeth.

6. Respondent did the root canal work on J.J.’s teeth using a modified version of the Sargenti Technique – a technique that, instead of cleaning and disinfecting the canals of an infected tooth, calls on a dentist to pack an infected tooth using a root canal filler which contains zinc-oxide, eugenol and paraformaldehyde, a potentially lethal substance. The Sargenti technique does not require the root canals to be completely disinfected before the tooth may be filled.

7. Soon after Respondent placed crowns on J.J.’s teeth, J.J. became dissatisfied with the comfort of the crowns. In addition, the bridge that Respondent put in J.J.’s mouth became loose. J.J. went to Respondent and tried to talk to him about the problems she was having with his work. However, Respondent dismissed J.J.’s concerns.

8. In March of 2002, J.J. then went to a subsequent treating dentist. This dentist took x-rays of J.J.’s mouth and found, among other things, a fractured bridge, crowns with severe overhangs and several root canals that were poorly done and incomplete. All of this dental work had been performed by Respondent.

9. Due to an illness, Respondent has not practiced dentistry nor occupied his office since March 2004.

10. In resolution of all current investigations before this agency concerning his licensure, Respondent consents to the issuance of the following Conclusions of Law and Order.


1. The Wisconsin Dentistry Examining Board has jurisdiction to act in this matter, pursuant to Wis. Stat. § 447.07(3), and is authorized to enter into the attached Stipulation and Order, pursuant to Wis. Stat. § 227.44(5).

2. The conduct described in paragraphs # 4-8 above, including the use of the modified Sargenti Technique, constitutes a violation of Wis. Stat. § 447.07(3)(h).



1. The Dentistry Examining Board hereby accepts the SURRENDER of the license of Kenneth R. Sachtjen, DDS, Respondent, to practice dentistry in the state of Wisconsin. The Board accepts this surrender in resolution of all pending claims against Respondent, including any Departmental claims for costs of investigation and/or prosecution. Case files 03 DEN 14, 03 DEN 15 and 04 DEN 071 are hereby closed.

2. IT IS FURTHER ORDERED that if Respondent ever petitions for reinstatement or applies for any other license or privilege from the Board, he shall pay the costs of investigating and prosecuting this matter, in the amount of $5,800.00, and a forfeiture of $ 2,500.00 before such petition or application may be considered.

3. The Order is effective on the date of its signing.
