Analytics: How Hygiene Interval is Calculated

Where does the "Hygiene Due Date" I see across Dental Intelligence come from?

Updated this week

The Hygiene Due Date in Analytics comes directly from your practice management software (PMS).


Because each PMS tracks hygiene recall differently, Dental Intelligence simplifies that information to show you one clear due date per patient — the next time they’re due for a hygiene visit.

Step 1: Determine If the Patient Is a Perio Patient

Dental Intelligence first checks whether the patient has ever had a perio procedure.

  • If yes, they’re treated as a Perio Patient and assigned a perio hygiene interval.

  • If no, they’re assigned a Prophy hygiene interval.

Once a patient has perio history, they’ll always be considered a Perio Patient for recall purposes.

Step 2: Identify the Correct Interval

We then determine how long that interval should be by checking your PMS in this order:

  1. Patient-Specific Interval — We look for a recall interval that includes “prophy” (for prophy patients) or “perio” (for perio patients).

  2. General Practice Default Interval — If there’s no patient-specific setting, we use your practice’s default hygiene recall interval.

  3. Fallback Defaults — If no interval is found, Dental Intelligence uses these default timeframes:

    • Prophy Patients: 181 days

    • Perio Patients: 120 days

Dentrix users: If your practice uses Dentrix, Analytics pulls the hygiene due date directly from the Continuing Care section in the patient chart.

Why It Matters

Keeping your hygiene intervals accurate ensures your recall lists, due dates, and scheduling tools all reflect the right timing — so no patient slips through the cracks.
