Root canal therapy #[14] ([3] canals: [MB, DB, P]). Diagnosis: [symptomatic irreversible pulpitis] with [symptomatic apical periodontitis]. Local anesthesia: [1.5] carpule(s) of [2% Lidocaine 1:100k epi] via [buccal infiltration]. Adequate anesthesia confirmed. Rubber dam isolation. Access obtained. Canals located and negotiated using [Rotary NiTi]. Working lengths established with electronic apex locator: [MB 19.5mm, DB 19.0mm, P 20.5mm]. Canals cleaned, shaped, irrigated with NaOCl. Obturation: [Warm Vertical], gutta-percha with sealer. Access sealed with [Cavit]. Post-operative radiograph taken; obturation within acceptable limits. Patient tolerated procedure well. Post-operative instructions given. Final restoration planned: [core buildup + crown #14].

“I'm Dr. Yasmin, a dentist who got tired of staying late writing notes. I used to search the internet for note templates that actually worked, and I could never find good ones. So I built ButterNote to make note writing feel as smooth as butter.
If the click-build flow above just saved you time, you'll love what's behind a free account: templates for practically every clinical scenario you'll see this week, with instant custom note generation. And if you want zero clicks at all, the iOS app handles that too. Ambient listening on your iPhone or Apple Watch turns each appointment into a finished note.

When to use this template
Use this root canal note template for non-surgical endodontic therapy on any tooth — anterior (D3310), premolar (D3320), or molar (D3330). A commonly missed point: these codes are billed by tooth type, not by canal count. A two-canal premolar and a one-canal premolar are both D3320; the CDT bundles canal complexity into the tooth-type code. All three codes exclude the final restoration, so plan and document the buildup and crown as separate procedures.
The medico-legally load-bearing items are the diagnosis pair and the isolation sentence. Record both a pulpal diagnosis (e.g., symptomatic irreversible pulpitis) and a periapical diagnosis (e.g., symptomatic apical periodontitis) — insurance reviewers and endodontists reading a referral both expect the two-part diagnosis. Rubber dam isolation is the standard of care in endodontics; an endo note without a documented rubber dam is a genuine liability problem if anything is ever aspirated or swallowed, so the sentence is non-negotiable.
Working lengths deserve per-canal documentation with the measurement method (electronic apex locator, confirmed radiographically). Note your irrigant, your obturation technique and material, and how you sealed the access. Finish with the post-operative radiograph — a complete minimal record shows pre-op pathology, working length verification, and the completed obturation. If the case is being referred out instead, switch to a limited-exam note with a referral line rather than this template.
Step by step: how to document this root canal therapy
- 1
Diagnose
Record the pulpal and periapical diagnosis supported by vitality testing and a pre-operative radiograph showing pathology.
- 2
Anesthetize and isolate
Local anesthesia delivered and confirmed; rubber dam placed — the endodontic standard of care.
- 3
Access and negotiate
Access cavity prepared; canals located and negotiated with hand or rotary files.
- 4
Establish working lengths
Per-canal working lengths measured with an electronic apex locator and/or working-length radiograph.
- 5
Clean and shape
Canals cleaned, shaped, and irrigated (NaOCl) to working length.
- 6
Obturate
Canals obturated (lateral condensation, warm vertical, or single cone) with gutta-percha and sealer.
- 7
Seal and image
Access sealed (temporary or definitive); post-operative radiograph confirms obturation quality; final restoration planned.
Tips for using this template
- check_circleAlways document rubber dam isolation. It is the endodontic standard of care, and an endo note without it is the single biggest liability gap if an instrument or irrigant incident ever occurs.
- check_circleRecord BOTH diagnoses — pulpal (e.g., symptomatic irreversible pulpitis) and periapical (e.g., symptomatic apical periodontitis). Reviewers expect the two-part diagnosis.
- check_circleBill by tooth type, not canal count: D3310 anterior, D3320 bicuspid/premolar, D3330 molar. Canal complexity is bundled into the tooth-type code.
- check_circleDocument working lengths per canal with the method — "established with electronic apex locator" or "confirmed with working-length radiograph."
- check_circleName the irrigant. "Irrigated with NaOCl" is the minimum; concentration adds defensibility.
- check_circleAll three RCT codes exclude the final restoration — document the planned buildup/crown as its own line so the treatment plan supports the follow-up claim.
- check_circleA complete radiographic record is pre-op (showing pathology), working length, and post-op (showing obturation). Missing the post-op film is a common audit flag.
- check_circleIf you left the tooth in temporary (Cavit/IRM), say so and note the recall — an open margin on a temporized endo tooth is a frequent source of failure and disputes.
