Hygiene Reappointment Rate — SGA vs PDDS
SGA reappt rate sourced from Dental Intel (broad denominator). PDDS calculates 12-month reappt rate (63%, 2024 industry 60%).
Methodology caveat (Brittney / Incline 5-6-26): Dental Intel's hygiene reappt calc uses a broad
denominator that includes all completed hygiene visits, producing 80–95% across SGA. SGA's internal calculation
(PMS-only, stricter denominator) shows ~62%, which would land closer to PDDS. Reading both numbers in this
dashboard at face value overstates the gap. Treat directional comparison only until the denominator
reconciliation lands.
