Endodontic Office Technology: The IT Guide for Owners and Office Managers

It is 8:05 on a full endodontic day. Two emergency add-ons from referring dentists are already booked, the workstation in operatory 2 is stuck on "connecting to server", and the CBCT acquisition PC is still capturing, onto a local drive nobody has checked in months. This guide is for practice owners and office managers who take that call: endodontic office technology seen from the IT side.

If you are choosing a support provider rather than planning the office, start with our dental IT support page. This guide gives you a technology map with a who-to-call table, a network zone plan, the upgrade dates that already affect endo software, a downtime runbook, the IT behind the referral report-back loop, a 15-question scorecard and a readiness checklist. It comes from Ian Lynch, who has 22 years in dental IT and oversees the NOC, onsite dispatch and client technology roadmaps. Every vendor fact below names its source and date, and the dates were checked on 26 October 2026.

What technology does an endodontic office need?

Endodontists' clinical technology (microscope, CBCT, apex locator, digital sensors) is the patient-facing half. The office-side half is what IT runs: the endo practice-management software and its server or cloud, the CBCT acquisition PC and where scans are saved, microscope capture into the chart, the network, phones, backup and security.

Most patient-facing lists stop at the clinical half. This guide covers the other half, the part that decides whether the schedule runs on time. For how Legend supports endo offices, see our endodontic IT services page.

What software do endodontists use? From the office side, the answer is an endo-specific practice management system (PMS). Systems you may run include TDO Software on an office server, TDOS (TDO's browser-based cloud software), PBS Endo (Henry Schein One), DentalEMR, EndoVision and XLDent. Around the PMS sit a CBCT viewer, a bridge to the 2D sensor software, and a capture path for the microscope camera. Comparing endo practice software is a separate buying decision; see our practice management software comparison for that.

The table compares a general office with an endo office from the IT side only. Clinical choices belong to the doctor.

Next step: use the map in the next section to write down what your office actually runs.

Your technology map: what runs where, and who to call

A technology map is a one-page list of every system in the office, where it lives, what IT must do for it and who to call when it fails. Fill it in once, keep it at the front desk, and update it whenever a computer, device or vendor changes. Blank cells are the first gaps to close.

Copy the table and replace the examples with your own systems. The "What IT must do" column comes from the vendors' own documents, so you can hold any provider to it.

Legend supports the IT environment for DEXIS, Vatech, Carestream, Planmeca/Romexis and Dolphin Imaging. If your sensors or CBCT run on one of those, our platform pages cover the IT side: Carestream imaging IT support, DEXIS IT support and Planmeca Romexis IT support. Note that TDO's CBCT integration article (March 2026) names only Carestream, J Morita and PreXion, so any other CBCT in a TDO office has no link to the chart beyond screenshots imported as JPG images.

Who do you call when something breaks?

Call IT first when one computer, every computer or the internet is affected, or when you cannot tell which. Call the software vendor when one application shows the same error on every computer and the network is fine. Call the CBCT or camera vendor when the device itself will not acquire. Write down the time, the computer name and the exact message first.

For the general rule in any dental office, see when to call the software vendor and when to call IT.

Gaps in your map? A Free Dental IT Assessment gives you written findings and prioritized recommendations on your computers, software, network security, backups and performance.

Next step: if your practice software lives on an office server, read the next section before the next hardware purchase.

Server or cloud: what your endo software asks of IT

An on-premise endo PMS needs a Windows server built to the vendor's spec, wired workstations and a supported SQL Server. A cloud PMS moves the patient database to the vendor, but the CBCT, sensor software, capture PCs, network and backup stay in the office. Either way, IT still has an office to run.

TDO's requirements page lists Windows Server 2016 to 2022 for the server, a private static IP address, a UPS and wired workstations (TDO KB 39, October 2025). The cloud products change less than the marketing suggests: TDO's data-import guide says "CBCT data remains accessible through its original software and viewer", and DentalEMR writes that moving to its cloud "does not remove every server in your office" because "CT and imaging software have their own on site requirements". TDO's own word "cloud" also covers three different things: Cloud Services on top of an office server, a Hybrid setup and TDOS. For PBS Endo, Henry Schein One's 2022 PBS Endo Enterprise hardware document describes an on-premise server-client system (Windows Server 2016 or 2019, SQL Server 2014 or later), and pbsendo.com states no hosted option (checked 26 October 2026); ask Henry Schein One for the current edition.

The full comparison, including Wi-Fi, RAID, SQL Server Express limits and working from home, is in our guide to endodontic software: server vs cloud. For the general-dentistry view, see cloud dental software (general dentistry).

Next step: whichever way you lean, plan the network around it, which is the next section.

How should an endodontic office network be zoned?

Zone an endodontic office network by what each device needs. Keep practice-software workstations, the server and the CBCT acquisition PC on wired connections, put tablets and GentleWave on a separate staff Wi-Fi, give phones their own segment, keep cameras and door systems apart, and give guests an isolated Wi-Fi that reaches the internet only.

Here is a zone plan you can hand to any IT provider and ask them to confirm, zone by zone.

What TDO asks IT to set on the network

TDO's best-practices article (TDO KB 107, May 2025) lists the settings an IT provider should verify on every computer. If your office runs TDO Software, use it as a checklist:

• • every computer has a unique name;
• • each workstation can ping the server by name, and the name resolves to an internal IP address;
• • the data folder is mapped by server hostname, not IP address, with the same drive letter everywhere, or set as the UNC path in TDO 12;
• • port 4150 is open on Windows Firewall;
• • the firewall or security appliance allows the domains .tdo4endo.com and .tdox.dental;
• • one antivirus product is installed, with TDO's exclusions set;
• • power management is off for hard disks, USB ports and network cards.

What the 2016 advice still gets right, and what it misses

The American Association of Endodontists' 2016 article on endodontic office design recommends Category 6 Ethernet cable, keeping data cable away from high-voltage wiring and fluorescent lighting, and a temperature-controlled, relatively dust-free server closet. That still holds. What it predates is the rest of today's office: tablets and GentleWave on Wi-Fi that must not share a network with guests, practice software that now depends on the internet circuit if it runs in the cloud, and the case for a second internet circuit from a different provider when the schedule cannot stop.

Cabling, closets and switch layout are covered in our guide to how a dental office network is set up and on our dental office network design page. Phone lines and fax are on our dental office phone systems page. Drops per operatory and connecting a second office belong to the build-out, covered in the build-out guide linked in the "where to start" section below.

Next step: once the network is mapped, follow the images, which is where most endo backups have gaps.

CBCT, microscope and sensor data: where it lands

An endodontic office has three data paths beyond the chart: microscope stills and video, 2D sensor images and CBCT volumes. Each must land in a folder the PMS can see and the backup copies. The common gaps are capture settings that differ from room to room and CBCT scans saved on the acquisition PC.

TDO's Carestream CBCT article says the folder where scans are saved after reconstruction "in many offices" is "a second internal hard drive on the Acquisition PC" (TDO KB 854, October 2025). If the backup covers only the server, those scans are not in it. TDO's Cloud Backup, for offices that use it, covers the database, X-rays, reports and uploaded images, and states: "CBCTs are excluded." (TDO KB 367, July 2026).

Ask your IT provider to name the folder for each of the three paths, on each computer, and show you that each is in last night's backup. The room-by-room setup, the integrations and where each CBCT brand saves its scans are covered in where your CBCT scans are saved. Restore testing for any dental office is in our dental backup and disaster recovery checklist.

Next step: check the dates in the next section against the server that holds those folders.

The endodontic upgrade calendar: what is already overdue

As of 26 October 2026, SQL Server 2016 has been out of Microsoft support since 14 July 2026, Windows 10 since 14 October 2025, and Windows Server 2016 ends on 12 January 2027, 78 days away. TDO also supports only its two most recent software versions, so an office that stops updating drifts out of support on its own.

Dates are from Microsoft's lifecycle pages (for example Windows Server 2016 and SQL Server 2016) and TDO's knowledge base, both checked on 26 October 2026.

One observation to raise with TDO rather than act on alone: TDO's v12 upgrade article (KB 619, February 2025) still lists SQL Server 2008 or SQL Server 2016, and both are now past Microsoft's end of support. Ask TDO which SQL Server versions your current build supports before you replace a server or upgrade the database.

For workstations, see our guide to Windows 10 end of life for dental practices. For the server decision itself, see dental server replacement vs cloud migration.

Next step: while the server is being planned, write down what the office does if it fails before the replacement arrives.

When the system goes down on a full endo day: the downtime runbook

A downtime runbook is a one-page plan the front desk follows when the practice software, the server or the internet fails. In an endodontic office it protects the referred emergencies first. It has four parts: what to prepare the night before, the call order for the first ten minutes, three operating modes, and the steps after recovery.

An endo schedule is built on referrals. When the system is down, the patients waiting are often in pain, and the dentist who sent them is waiting for a report. The runbook keeps the day moving without guessing.

The night before

• • Print or export tomorrow's schedule with the referral notes.
• • Keep a printed list of the day's emergency add-ons and how to reach each patient.
• • Keep a printed contact list for your referring dentists.
• • Keep paper consent and medical-history forms in a labelled folder.
• • Check that last night's backup finished without errors. TDO, for example, makes the doctor responsible for checking it daily (TDO KB 125).

Three operating modes

• • Full: everything works. Carry on.
• • Imaging-only: the CBCT and sensor PCs still capture locally. Chart on paper, note which images belong to which patient, attach them after recovery.
• • Paper: treat the referred emergencies first, keep scheduled patients informed, and call any referring office whose patient's report will be late.

After recovery

• • Back-enter the paper notes and attach the local images to the right charts.
• • Check that letters queued during the outage went out.
• • Write down what failed, when, and what fixed it, and review it with IT within a week.

If your practice runs TDO Software, TDO publishes a "Fire Drill" that rehearses running the office from the admin workstation if the server fails, and says the office can be "up and running in 30 minutes" if its backup protocol is followed (TDO KB 675, October 2023; TDO's claim). TDO's responsibilities article lists "Perform a monthly Fire Drill" among the IT professional's duties (TDO KB 125, February 2026). The drill and the backup design behind it are covered in the server vs cloud guide linked earlier. For an internet outage, see what to do when the office internet goes down.

Next step: print the runbook and walk the front desk through it once before you need it.

Referral reports and images: the IT behind the report-back loop

The referral loop runs in two directions. The referring dentist sends the patient, the reason and a diagnostic radiograph. The endodontic office sends back a consult note, a final report with pre-op and post-op images, and recall. Each direction runs on IT the office controls: email, Word or a cloud letter tool, and often a referring-doctor portal.

When a referring dentist says they never got the report, the cause is usually one of a short list. The table below comes from TDO's knowledge base, because TDO documents these failures in detail; if your office runs other software, ask its vendor for the equivalent list.

For PBS Endo offices, Henry Schein One describes "email templates to use as letters to referrals" on its product page; ask your vendor how letters and images are sent from your edition. TDO offices that use TDO Cloud Backup should remember the line from the last section: CBCTs are not in it.

Inbound CBCTs on discs and drives

Scans also arrive the other way. An AAE Communiqué notes that patients increasingly bring CBCTs on CDs and jump drives, and its author advises that "a second scan at the endodontic practice will likely be acquired" (Bruno Azevedo, "Thanks, but no thanks", April 2022; a clinical view, attributed to its author). The IT consequences are practical: decide how removable media is imported and scanned for malware before it touches a clinical PC, and count both the inbound scan and any new one in your storage plan. Carestream offices running TDO can import a disc CBCT with TDO's CBCT Syncer utility (TDO KB 871, Carestream-specific). The import steps are covered in the CBCT storage guide linked in the imaging section above.

On imaging for referrals, the AAE's Treatment Standards (2019) say intraoral radiographs "should be considered the imaging modality of choice", with CBCT where justified. The current CBCT guidance is the AAE and AAOMR joint position statement on CBCT in endodontics, 2025 update, which the AAE says replaces the 2015 statement with 12 recommendations (AAE news release, 14 Jan 2026); clinical questions about it belong with the doctor.

Encrypted email for reports is covered on our email security for dental offices page.

Next step: once reports flow, check who can reach them, which is the security section.

Security for an endodontic office

An endodontic office sends reports and images to many outside offices every week, handles CBCT studies large enough to tempt staff into consumer file-share links, and often runs a referring-doctor portal that is an external login. Security starts with those three facts, then covers the controls every dental office needs.

The checklist describes what a practice should have in place. It is not a list of any provider's services, and it is not legal advice.

1. 1. Multi-factor authentication on email, any cloud practice software and the admin side of the referral portal.
2. 1. A vendor list. Keep a list of every vendor that stores or moves patient data (PMS cloud, referral portal, backup, email) and where each agreement is filed. Which vendors need a business associate agreement is a question for your compliance adviser.
3. 1. No consumer file-share links for CBCT studies or reports. Agree one channel with your referring dentists and use only that.
4. 1. Unique logins for every person. No shared front-desk account.
5. 1. A remote-access list. TDO's setup checklist has TDO Support install its services through remote access to your server (TDO KB 821). Keep a list of every vendor that can connect, and review it.
6. 1. Patching inside the vendor's supported versions. Windows and Office updates on schedule, and the PMS kept within the versions its vendor supports (TDO KB 1059).
7. 1. One antivirus product, with the PMS vendor's exclusions documented (TDO KB 107).
8. 1. User Account Control, decided deliberately. TDO KB 107 says UAC must be disabled to use the QuickBooks Sync application or drag and drop into the image organizer. That is a security trade-off for the practice and its IT provider to decide and write down.
9. 1. Backups that match the vendor's design. In TDO offices, TDO's own backup utility is the primary backup, and TDO says it "cannot restore your data" from tape or other backup applications (TDO KB 675). IT's job is to protect and copy what that utility writes, add the folders it does not cover such as CBCT scans, and test restores. The details are in the server vs cloud guide.

For the HIPAA technical safeguards in more depth, see HIPAA Security Rule changes for dental practices, ransomware and phishing protection for dental offices, dental ransomware recovery and our dental cybersecurity page.

Next step: use the questions in the next section to find out whether your IT provider covers all nine.

Questions to ask an IT company before you hire it for an endodontic practice

Ask questions that only someone who has worked in endodontic offices can answer well: which endo software they know, where your CBCT scans are saved, when they last restored your data and what happens at 8 a.m. on a bad day. Score each answer 0, 1 or 2. Under 15 out of 30 shows where the gaps are.

Scoring: 24–30, a strong fit · 15–23, gaps to fix in writing · under 15, get a second opinion.

Questions 2, 5, 7 and 9 are explained in endodontic software: server vs cloud; question 3 in where your CBCT scans are saved; question 12 in the endodontic build-out guide. For the contract questions any dental office should ask, see our 20 questions to ask before signing a dental IT contract.

Scored under 15? That is what the Free Dental IT Assessment is for.

Next step: send the 15 questions to your current provider and to any provider you are considering.

The endodontic IT readiness checklist

This checklist pulls together the actions from every section above. Work through it with your IT provider once a year, and again before a server replacement, a software change or a new location. Each item points back to a section of this guide or to the vendor document it came from.

Next step: mark each unticked item with an owner and a date.

Opening, adding or changing: where to start

Start with the guide that matches the project. Opening a new endodontic office, adding a location and changing practice software each have their own order of work, and each has its own guide so this one can stay focused on the office you run today.

• • Opening an office or adding a location: our endodontic office technology build-out guide covers the endo-specific parts, and our dental startup IT page covers the rest of an opening.
• • Deciding between a server and the cloud: start with the server vs cloud guide linked in the server section.
• • Ten or more offices: see DSO IT support.

For a local view of specialty practices, see our specialty practice IT guide for Dallas.

Endodontic offices Legend has worked with

Two endodontic projects show the kind of work involved. In May 2026 Legend's team was on site at Transcend Endodontics in Midlothian, Texas, building out the technology backbone for a new endodontic practice that was under construction. At Texas Roots Endodontics in Fort Worth, Texas, Legend's February 2024 post marking the practice's first year says Legend had provided IT infrastructure, technology installation and daily oversight since day one.

What does IT cost for an endodontic practice?

Legend's published price line for monthly IT support reads: Starting at $360 per month. Hardware procurement, major cabling projects and software licensing are quoted separately, and startups are always custom quoted. Plans are described on our dental IT support page, and what drives the cost for any dental office is explained in our dental IT support cost guide.

The bottom line

Endodontic office technology protects a referral schedule, so the IT side matters as much as the clinical side. The good news is that the vendors publish most of what IT needs to know, from server versions to backup rules. Start with the technology map and the readiness checklist, then use the 15 questions to see whether your IT provider is working from the same documents. Our IT support for endodontic practices page covers how we work with endo offices.
