tooth 0.5.0

Naming

• The arch visualization is now consistently called an odontogram throughout the package. build_odontograph() has been renamed to build_odontogram().
• build_odontograph() is retained as a deprecated alias that forwards to build_odontogram() with a warning, and will be removed in a future release.

Caries activity handling

• calc_dmft() and calc_dmfs() gain arguments to control whether caries activity is required for a lesion to be scored as decayed:
  • consider_activity (default TRUE) — the overall setting.
  • consider_activity_coronal / consider_activity_root (default NULL, i.e. inherit the overall setting) — per-component overrides.
• Set consider_activity = FALSE to count every lesion in decayed_codes regardless of activity, matching the conventional epidemiological D(3)MFT definition. When activity is not considered, the activity column need not be present.
• Behavior change: root caries now honours the activity setting as well. Previously root lesions were counted regardless of activity, which was inconsistent with the coronal calculation. To restore the old root behaviour, pass consider_activity_root = FALSE.

Tooth numbering

• Behavior change: for primary dentition, tooth_convert() now returns the standard ADA Universal letters A–T (A = upper-right second primary molar … T = lower-right second primary molar) instead of the previous numeric 51–70 encoding. Permanent Universal numbering (1–32) is unchanged.

Documentation

• Documented the default decayed_codes = c(3, 4, 5, 6) as the D3 threshold (ICDAS 3–6, i.e. cavitated lesions; enamel-only ICDAS 1–2 lesions treated as sound), with guidance on using a D1 threshold instead.
