ITEM 1. SECURITY AND ISSUER

                This Amendment No. 3 to statement on Schedule 13D (this "Statement") relates to the Common Stock, no par value (the "Common Stock"), of Dendrite International, Inc., a New Jersey corporation (the "Issuer" or the "Company"), the principal executive offices of which are located at 1405 U.S. Highway 206, Bedminster, NJ 07921. This Amendment No. 3 amends and restates in full each of the items set forth below. Terms not defined in this Amendment No.3 shall have the respective meanings given to such terms in the Schedule 13D originally filed on December 13, 2005 ("Original Schedule 13D").

ITEM 4. PURPOSE OF TRANSACTION

                MMI Investments purchased the Shares as part of its investment activities. The Reporting Persons intend to review and evaluate the investment by MMI Investments in the Common Stock of the Issuer on an ongoing basis and may, depending upon their evaluation of the business and prospects of the Issuer, or such other considerations as they may deem relevant, determine to increase, decrease, or dispose of MMI Investments' holdings of Common Stock. As a part of such review and evaluation, the Reporting Persons may communicate with the Issuer's management, directors and other shareholders.

                In order to allow MMI Investments to increase its ownership to more than 10% of the outstanding Common Stock of the Issuer, MMI Investments on February 6, 2006 filed a Notification and Report Form under the Hart Scott Rodino Antitrust Improvements Act of 1976, as amended ("HSR Act") and has requested early termination of the waiting period pursuant to the HSR Act. The Issuer made its responsive HSR filing on February 21, 2006, and the Federal Trade Commission could exercise its discretion to grant such early termination at any time following such filing; absent an early termination or a governmental request for additional information, the waiting period will expire on March 8, 2006. Upon expiration of the waiting period, the Reporting Persons would be permitted under HSR to purchase additional shares of Common Stock such that the Reporting Persons would hold up to $113.4 million in total market value of Common Stock at the time of such purchase. However, MMI Investments will not purchase Common Stock of the Issuer if, as a result of the purchase, it would own more than 14.9% of the outstanding Common Stock (which would have represented a market value of $79,960,031 based on the number of shares outstanding at October 31, 2005 and the closing price on February 17, 2006).

                Other than as described in this Item 4, neither Reporting Person, nor, to the knowledge of each Reporting Person, any individuals listed on Schedule I, has any current plan or proposal that relates to or would result in any of the transactions or other matters specified in clauses (a) through (j) of Item 4 of Schedule 13D; provided that the Reporting Persons reserve the right to develop such plans or proposals.

ITEM 7. MATERIAL TO BE FILED AS EXHIBITS

                See Exhibit Index appearing elsewhere herein, which is incorporated herein by reference.
