What would we consider a root stump in dmft index under a decay of Missing

I need to invoke the medical-library skill first since this is a dental/clinical question about the DMFT index (Decayed, Missing, Filled Teeth).

DMFT classification root stump deciduous tooth crown root

Based on the search results, I found the key information about root stumps in the DMFT index classification.

Root Stump in DMFT Index (Missing Component)

A root stump is considered a tooth that is PRESENT in the DMFT index, even though only the root remains. According to dental caries classification guidelines:
A tooth is considered present even when the crown is destroyed and only the roots are left.
This means that:
  • Root stumps are NOT counted in the "M" (Missing) component of DMFT. They would only be counted if they show decay or have been filled.
  • If a root stump shows carious decay, it would be classified under "D" (Decayed)
  • If a root stump has been restored/treated, it would be classified under "F" (Filled)

Key Points about DMFT Missing (M) Classification:

The "M" component specifically counts teeth that have been extracted or are completely absent due to caries. Teeth NOT counted in the M component include:
  • Unerupted teeth
  • Congenitally missing teeth
  • Teeth removed for reasons other than caries (orthodontic extraction, trauma, etc.)
  • Deciduous teeth retained in the permanent dentition
  • Root stumps (since the tooth is still technically present, even if only the root remains)
The DMFT index distinguishes between complete tooth loss and partial tooth structure loss - if any part of the tooth (root or crown) remains in the mouth, the tooth is considered present and coded based on its condition (decayed, filled, or sound).

"to be extracted" DMFT index root stump decay missing

Based on the search results, I now have the specific information about how root stumps indicated for extraction are classified in the DMFT index.

Root Stump Indicated for Extraction in DMFT (Missing Component)

A root stump that is indicated for extraction is classified as "M" (Missing) in the DMFT index, even though the tooth is still physically present in the mouth.

Key Classification Rules:

According to DMFT recording principles:
"Also included should be those teeth which are so badly decayed that they are indicated for extraction"

Specific Coding:

In modified DMFT protocols, this is designated as:
  • Code 10: "To be lost/extracted due to caries" - This applies when more than two-thirds of the crown has been lost or the tooth is abscessed, but there may be no visible sign of decay.

Distinguishing Features:

A root stump indicated for extraction is counted as "M" (Missing) when:
  • More than 2/3 of the crown is destroyed/lost
  • The tooth is abscessed due to caries
  • The tooth is so severely compromised that extraction is clinically indicated
  • The destruction/damage is due to caries (not trauma, orthodontics, or other causes)

Important Distinction:

This differs from a simple root stump that remains in the mouth:
  • Root stump NOT indicated for extraction = classified as "D" (Decayed) if carious, or remains present
  • Root stump INDICATED for extraction = classified as "M" (Missing) in the DMFT score
This classification accounts for the tooth's prognosis and treatment status, recognizing that severely compromised teeth indicated for extraction contribute to the patient's caries experience in the same way as already-extracted teeth.
