Dental Recall System: Count Who Comes Back

Your dental recall system already keeps three lists: who is due, who is booked and who is overdue. The lists do not show how many of last quarter's due patients sat in the hygiene chair.

Quick answer

• Open the overdue list today and count it, split by how many months each patient is past due.
• Find the setting that hides a patient after a set number of reminders, and read its value.
• Divide recall visits completed by patients who came due, once a quarter.
• Pre-book the next visit before the patient leaves, and count those separately from reminder bookings.
• Keep paid third-party promotions out of recall messages.

Three lists, and what they are called

Practice software keeps a due date per patient. The names differ by vendor, so open yours and find the three lists in the table.

The names come from Open Dental's Recall List page and Dentrix Enterprise's own blog, which tells offices to review the Continuing Care list monthly. I could not find a public Patterson page for Eaglesoft, so I leave it out. For software choice, see the dental practice management software comparison.

Pull the overdue count before lunch

The steps follow Open Dental's manual; look for the same filters in your own system. You need only the practice software and a pencil.

1. Open the Recall List. In the View section, set To to today's date and check Include Reminded, or recently reminded patients stay hidden.
2. Decide what From should be. The manual says to leave it blank to include patients "who have never had a recall procedure set complete."
3. Sort by Due Date and count the rows in three bands: under 3 months past, 3 to 12 months, and over 12.
4. Read the #Remind and LastRemind columns. An overdue patient with 0 in #Remind has had no reminder since the last recall visit.
5. Scan the Status column for patients marked as contacted who never booked.

Write the three numbers on paper; next quarter you compare against them.

How the recall rate is worked out

Count it once a quarter, over the same dates.

Recall rate = recall visits completed ÷ patients who came due × 100

Count the pre-booked visits and the visits booked after a reminder in separate columns. They tell you different things about your front desk and your reminders.

The gap between 76.9% booked and 67.7% completed is the number to watch. If it is wide, look at your reminders; the appointment reminder guide covers that timing.

Why patients drop off the list

A patient can leave the overdue list without ever booking, because software hides people for reasons you set months ago.

Check these in whatever you use:

• How many days a reminded patient stays hidden. In Open Dental's Setup Recall, a blank day count hides the patient indefinitely.
• The reminder maximum.
• Whether any future appointment removes a patient from the list.
• What happens when a recall is disabled or the patient's status changes.

Open Dental's patient recall page says the Always Disabled box removes the due date. Open Dental also disables recall automatically when a patient's status is anything other than Patient.

Ask your software vendor to show you four things:

• The setting that removes a patient from the overdue list, and its current value.
• How to run the overdue list by months past due.
• Where a pre-booked visit and a reminder booking land in different columns.
• Whether the list exports with the last reminder date.

Six months is a habit, not a rule

A recall interval is a clinical decision, and the evidence does not support one number for everyone. England's NICE guideline CG19 puts the shortest routine interval at 3 months and the longest at 24 months for adults and 12 months for under 18s. It covers NHS dental care in England and Wales, so treat it as evidence, not a US rule.

The 2020 Cochrane review of two trials with 1,736 participants found little to no difference in tooth decay, gum disease or quality of life between six-month and risk-based check-ups for adults. For children it found the evidence insufficient.

Your dentist sets each patient's interval, and the software stores it.

The insurance cap shapes what you can book

A dental plan can cap cleanings, so a patient on a 3-month interval may pay for the visits past the cap.

That is one plan's rule, and others word it differently. Ask the front desk to note the frequency limit next to the interval before booking a 3-month patient.

Rules for the messages

Under HIPAA, a reminder to book a patient's own cleaning is a treatment communication, not marketing. The marketing definition in 45 CFR 164.501 carves out communications "for treatment," but not when a third party pays you to send it. If a whitening brand pays to appear in your recall email, the email becomes marketing and needs each patient's signed authorization first.

For the consent side of texting, see HIPAA and text messaging.

In Canada, CASL lets you rely on implied consent for two years after a patient's last purchase of a service and six months after an inquiry. A recall email to a patient last seen three years ago may therefore need fresh consent if it counts as a commercial message. HIPAA does not apply in Canada, where patient information falls under PIPEDA or a provincial health privacy law such as Ontario's.
