★ DoctorScribe — Complete Clinic Management
OHI-S, plaque scores and perio charts in one tap
DoctorScribe's perio module supports OHI-S, PI, GI, BOP, CPITN and full-mouth pocket charting with auto-trend graphs — built for dental clinics doing high-volume recalls.
Clinical Disclaimer: OHI-S requires the six index teeth to be erupted and scoreable. If an index tooth is missing or unscoreable, substitute as per Greene-Vermillion rules (alternate fully-erupted tooth in the same sextant). Do not substitute across midline. Always verify against your local prescribing reference and apply clinical judgment.
Plaque control, tracked patient by patient
DoctorScribe logs OHI-S at every recall, plots oral-hygiene trends per patient, prints colour-coded patient education sheets in multiple languages, and reminds patients via WhatsApp.
