How to Apply to an Endodontic Residency
A practicing endodontist's playbook · Dr. Jason Kung, OHSU '16
There is no consolidated guide to applying to endo residency anywhere on the open internet — most of the real information is buried in 800-post forum threads. This page is the playbook I wish I had: timeline, application pieces, what program directors weigh, and what I'd do differently if I were applying today. For live cycle data — interview-invite tracking, who's heard from where this week — the SDN PASS thread is the source of truth, and I link to it below.
The timeline
The cycle from "I'm thinking about endo" to a match result spans roughly 18 months. The biggest single mistake is starting the application pieces in May or June rather than the prior winter — letters of recommendation in particular benefit from months, not weeks, of lead time.
D3 spring / 1–2 years before applying
Decide and prepare
Confirm endo is what you want — shadow at least two endodontists in different practice models. Start a CBSE study plan if your target programs require it. Begin building relationships with endo faculty for letters of recommendation.
January – April (year of application)
Identify programs & take CBSE
Pull the AAE program directory. Build a target list of 15–25 programs based on philosophy (academic vs. clinical heavy), length (2 vs. 3 years), and location. Take the CBSE early enough to retake if needed.
May – July
PASS application & personal statement
PASS opens. Request letters of recommendation early — at least one from a practicing endodontist. Draft and re-draft the personal statement. Have it read by a recent matcher and an experienced endodontist, not just classmates.
July – September
Submit
Submit broadly. Send a brief professional email to programs of strong interest after submission. Update programs if you have new publications, posters, or presentations.
October – February
Interviews
Most interviews run in this window — increasingly virtual, with select in-person second-look days. Prepare a short, well-organized case portfolio. Have a clear answer to 'why endo' and 'why this program' for each interview.
February – March
Match results & next steps
Match results release. If matched: relax briefly, then start preparing for residency. If unmatched: triage immediately — GPR/AEGD, additional GP experience, CBSE retake, and a structured plan for reapplying.
The application — piece by piece
Programs evaluate the application as a whole, not as a sum of scores. A 90 on the CBSE without a clear personal statement and weak letters won't outperform an 80 with a coherent story and strong endodontist letters. Strengthen the weakest piece, not the strongest.
Personal statement
The most-read part of your application after your CV. Lead with one specific story or angle — not a generic 'I love teeth' opening. Structure: hook paragraph → why endo → why you'd be a good resident → conclusion. Aim for one page, double-spaced. Have it read by someone who matched in the last 2–3 years.
Letters of recommendation
Three is standard. At least one from a practicing endodontist who can speak to your clinical interest beyond the lecture hall. One from a dental school faculty member who can speak to your character. The third can be a GP supervisor (especially valuable if you have practice experience). Ask early and provide your CV, personal statement draft, and a list of programs.
CBSE
The Comprehensive Basic Science Examination is increasingly used as a screening filter at competitive programs. The bar varies by program; 75 is a common floor and 85+ is often cited as competitive. If your first attempt is well below your target, retake it. Programs see all attempts at most institutions.
GP experience
Many programs strongly prefer 1–3 years of general practice before residency. If you're applying straight out of dental school, you'll be competing against more experienced applicants — be honest with yourself about whether that's the right call or whether a year of GPR/AEGD or private-practice GP would strengthen your application.
Programs that require the ADAT
The Advanced Dental Admission Test is required (in addition to or in place of the CBSE) at a subset of programs. As of recent application cycles, the following programs have required ADAT scores. Always verify directly on each program's website — requirements change.
What I'd tell myself if I were applying today
Five things I noticed during my own cycle that aren't obvious from the application instructions.
Apply broadly. Twenty programs is not paranoid.
Endo has roughly 200 spots across ~60–65 programs nationwide. Strong applicants regularly receive only one or two acceptances — sometimes from programs they almost didn't apply to. The marginal cost of one more application is small; the cost of not matching is a year.
Network at the AAE Annual Meeting.
If you can possibly afford to go in your application year, go. School alumni receptions, faculty introductions at sessions, and informal conversations at vendor booths convert into interview invites at a higher rate than almost anything else you can do. Attendance at AAE has crossed 600 students in recent years — be early to the receptions.
Build a case portfolio.
A simple, well-organized PDF of 6–10 cases with pre-op/post-op radiographs, brief diagnosis, and what you learned. Bring it to interviews. Even programs that don't ask for one will skim it and remember you for it.
Have a clean answer to 'why this program.'
Generic enthusiasm reads as low effort. One specific reason — a faculty member's research, the program's microsurgery emphasis, the patient population, the relationship with the medical school — is enough. Programs notice when you've actually read their website.
Be honest about red flags in interviews.
If you have a low CBSE, a class-rank gap, or a non-traditional path, address it briefly and move on. Programs are evaluating whether you can finish and pass boards — not whether your application is perfect.
Live cycle data — the source of truth
This page is intentionally evergreen — it doesn't go stale because it doesn't try to track who's interviewing where this week. For that, the right place to be is Student Doctor Network's annual PASS thread. It's where applicants share interview invites in real time, ask each other CBSE questions, and where program directors, recent matchers, and practicing endodontists (including me) occasionally weigh in.
Questions about your specific application?
I'm happy to read a personal statement draft, look at a program list, or talk through whether a year of GP would strengthen your application. There is no charge for this for current dental students or recent graduates.
