296 people applied to match into a periodontics residency in the 2026 cycle, competing for 132 available positions, and 129 matched — per the Postdoctoral Dental Matching Program's Results of the Matching Program for 2026–2027 Positions.
That's the full picture the source publishes: a single year's applicant, position, and match counts, with no acceptance rate and no multi-year trend behind them for this specialty.
The 2026 Match, by the numbers
The Postdoctoral Dental Matching Program, run by National Matching Services, publishes participation and outcome counts each year for every specialty program type in the dental match.
Its Results of the Matching Program for 2026–2027 Positions reports 296 applicants participating in the periodontics (PERIO) match, competing for 132 available residency positions.
129 of those applicants matched into a periodontics residency spot.
That left 3 of the 132 positions unfilled.
Why there's no five-year trend to report
A single year's numbers don't say whether periodontics is getting harder or easier to enter over time — only a published multi-year series can answer that, and periodontics doesn't have one in this source.
The Postdoctoral Dental Matching Program's five-year applicant series covers just three of the eight program types it tracks: orthodontics, oral and maxillofacial surgery, and pediatric dentistry.
Periodontics isn't among them, so no trend — rising, falling, or flat — is reported here for this specialty.
The 296 / 132 / 129 figures above are the only periodontics numbers the source publishes.

Why you won't see an acceptance rate here
It's tempting to divide 129 matches by 296 applicants and call the result an acceptance rate.
Don't — the Match's own totals show why that math doesn't hold up.
Applicants can rank more than one program type on their Match list, so the per-specialty applicant counts overlap: added together, the eight tabulated program types in the 2026 Match sum to 3,554 applicants against an overall pool of only 3,213 people.
That overlap means the 296 people counted in the periodontics numbers aren't all applying to periodontics alone — some are also ranking other program types, hedging their options.
A rate built from that count would understate what each individual applicant's real odds actually were.
What the Match numbers do support, reported exactly as published: 296 applicants participated in periodontics for 132 positions in 2026, and 129 matched.
That's the shape of the competition — not a percentage.
What the numbers don't tell you
The Postdoctoral Dental Matching Program publishes participation and outcome counts — it doesn't publish why any individual applicant matches or doesn't, and neither does this article.
Board scores, class rank, and research all plausibly factor into a competitive residency application the way they do for any other, but the Match's own results don't break down which of those matters most or by how much.
What isn't published — and what this article won't guess
Where this fits, and what it doesn't answer about pay
Matching in is one step on the path described in full in how to become a periodontist; what the residency itself requires once you're in — duration, teaching, research — is covered in periodontics residency: what CODA requires.
What comes after residency — voluntary ABP certification — is covered in board certification in periodontology.
For the role overview, see what a periodontist does.
Pay doesn't move with these Match numbers either: there's no periodontics-specific federal wage figure, because the U.S. Bureau of Labor Statistics groups periodontists under the broad "Dentists, all other specialists" category (SOC 29-1029) rather than tracking the specialty on its own code.
