What Is TDO?
TDO -- The Digital Office -- is a complete practice management system built exclusively for endodontists. It covers scheduling, clinical charting, financial management, reporting, imaging, patient communication, and referral tracking in a single integrated platform. The defining philosophy is paperlessness: TDO was designed from the ground up to eliminate every piece of paper in an endodontic office, from patient registration to consent forms to clinical documentation.
The heart of the system is the Diagnosis Page, which TDO describes as the most comprehensive radiographic and clinical examination form ever seen in a dental software program. It captures every diagnostic data point an endodontist needs in a structured, standardized format that makes record-keeping consistent across providers and over time.
Dr. Gary Carr and office manager Amy Taylor began developing TDO in the late 1990s as a natural complement to microscope-enhanced endodontics. They tested Version 1.01 in 1998 and launched commercially in 2000. The company has grown from 3 employees and 10 users to nearly 20 employees serving 2,000 users worldwide. TDO has expanded its strategic partnership with Sonendo (makers of the GentleWave system), further cementing its position in the endo tech ecosystem.
Who Is It For?
Solo endodontists: TDO handles everything a single-provider endo practice needs without the bloat of features designed for general dentistry. The workflow is optimized for the endo patient journey: referral in, diagnosis, treatment, follow-up, referral communication back to the GP.
Multi-provider endodontic groups: Standardized documentation templates ensure consistency across providers. The referral tracking system manages relationships with dozens or hundreds of referring general dentists.
Endodontists transitioning to a fully digital office: If you are still using paper charts, paper consent forms, or manual referral letters, TDO is the single system that replaces all of it. The InfoGrabber feature handles digital patient registration and health history.
Not for general dentists: TDO is endodontics-only. If you do not practice endo, this software will not work for you. That is a feature, not a bug -- the specialization is what makes it excellent.
Key Features
The Diagnosis Page: A structured radiographic and clinical examination form that captures pulp diagnosis, periapical diagnosis, previous treatment history, symptoms, testing results, and treatment recommendations in a standardized format. This alone sets TDO apart from any general dental PMS trying to serve endo.
Complete Paperless Workflow: Patient registration, medical/dental/pain history, consent forms, clinical charting, scheduling, financials, and reporting all live in TDO. The InfoGrabber handles online patient check-in so patients complete forms before they arrive.
Referral Management: Tracks referring doctors, generates referral acknowledgment letters, sends post-treatment reports back to the GP, and provides analytics on referral patterns. For an endo practice where relationships with general dentists are the lifeblood of the business, this is critical infrastructure.
Digital Imaging Integration: Works with every major digital radiography system including XDR, Carestream, Dexis, Schick, Sirona, Gendex, ScanX, and any manufacturer providing a TWAIN driver. Integrates CBCT and microscope photography into the patient record.
Financial Management: Billing, insurance claims, payment tracking, and QuickBooks integration to eliminate double entries. Practice reports cover production, collections, referral statistics, and procedure analytics.
Post-Treatment Follow-Up: Automated post-treatment questionnaire generation for tracking outcomes. Structured follow-up scheduling and recall management specific to endo follow-up protocols.
