US Equivalent

In the US, specialization is via ADA-recognized residency programs (2–6 years) leading to a certificate; some programs award an MS, MSc, or MDent degree concurrently.

Note: "MDS" in the US sometimes denotes "Master of Dental Science" (academic master's), not a clinical specialty credential.
