D1352 — Preventive resin restoration (PRR)
A preventive resin restoration sits deliberately between a sealant and a filling. D1352 is the version in resin.
D1352 is the preventive code for preventive resin restoration, PRR.
The sections that follow deal with the requirements, the fee, the claim, and the neighbouring codes — the last of which is where most of the confusion starts.
What D1352 specifies
Material — resin. Resin here means a tooth-coloured polymer material rather than a metal or a ceramic. It handles well, matches tooth shade closely and is inexpensive, but it is softer than both enamel and porcelain, so it wears and discolours over a period of years rather than decades. The material is part of the code rather than a choice made afterwards, so D1352 is only the right code if that is what was actually used.
What preventive resin restoration involves
A preventive resin restoration sits deliberately between a sealant and a filling. The groove has early decay — enough that sealing straight over it would be unwise, but not enough to justify cutting a conventional cavity preparation. So the dentist removes only the affected enamel with a very small bur or an air abrasion tip, restores that tiny defect, and covers the whole groove system with sealant material. The philosophy behind it is minimally invasive dentistry: every millimetre of tooth removed is gone permanently, and a tooth's restorative life is a one-way street from sealant to filling to onlay to crown. Delaying entry onto that path is worth real effort.
When this treatment is used
Used on a permanent posterior tooth with demineralisation or very early decay confined to the enamel of a pit or groove, in a patient whose overall decay risk makes watching it unattractive. It is a paediatric and young-adult code in practice.
Why plans argue about it
This code lives in a gap that benefit design handles badly. Some plans process it as a sealant and pay the sealant allowance; some process it as a one-surface restoration; some deny it as neither. The clinical reality — a small amount of decay removed plus a sealant — is genuinely both things, and no payer category fits it cleanly. In practice offices submit it and accept whichever allowance comes back. If you are quoted a preventive resin restoration, asking what your plan is likely to allow is reasonable, but the answer may honestly be "we will find out".
Questions about D1352
What is a preventive resin restoration?
A minimal treatment for a groove with very early decay: only the affected enamel is removed, the small defect is restored, and the whole groove is sealed.
Is a PRR the same as a filling?
No. A filling involves a conventional cavity preparation into dentine. A preventive resin restoration removes only a small amount of enamel and relies mostly on sealant material.
Will insurance cover D1352?
It varies. Many plans reprice it to the sealant allowance, some treat it as a one-surface filling, and a few deny it. Ask what your plan is likely to allow.
D1352 — what is it?
The procedure behind the number is preventive resin restoration, PRR, filed under preventive.
What is the typical fee for D1352?
Most private fees fall in $60–$180. Geography accounts for more of that spread than anything clinical.
