The statement 'Patient records must be kept for at least 3 years after the last entry' is true.

• A. True
• B. False
• C. Not specified
• D. Only if required by state law

Answer: (B)

Retention of patient records is determined by state law and dental board rules, not a universal fixed period. In Iowa, the minimum retention period is longer than three years—commonly at least seven years after the last entry (and in some cases, records may be kept until the patient reaches a certain age or for a defined period after the last treatment). Because the statement claims a universal minimum of three years, it’s not correct. Always check current Iowa statutes or Board guidelines for the exact requirement. (Federal privacy rules like HIPAA play a separate role, but state law sets the specific retention period for patient records.)
