This page provides a list of the FHIR artifacts defined as part of this implementation guide.
These define constraints on FHIR resources for systems conforming to this implementation guide.
| Dental Apical Diagnosis |
Apical diagnosis for one FDI position. A source root may qualify the finding through bodySite locationDetail. |
| Dental Caries Finding |
Surface-qualified dental caries assessment. The result is required from the Dental Core caries ValueSet; lesion activity and ICDAS severity are distinct components, and radiographic depth is a distinct DentalRadiographicCariesDepth observation. A finding without a surface is root caries only when its result says so (root-caries, cavitated-root-caries); with a caries or secondary-caries result it records a lesion whose surface was not recorded. |
| Dental Cephalometric Analysis |
Imaging-derived cephalometric measurements and reference values without national billing or workflow semantics. |
| Dental Cephalometric Analysis Panel |
A panel that groups atomic imaging-derived cephalometric measurements without changing the released component-based cephalometric analysis profile. |
| Dental Cephalometric Landmark |
An imaging-derived cephalometric landmark with physical UCUM millimetre x and y coordinates, an optional z coordinate, a declared coordinate frame, and explicit source evidence. Pixel coordinates are out of scope. |
| Dental Cephalometric Measurement |
An imaging-derived cephalometric measurement with explicit method and source evidence. |
| Dental Chart State |
Lossless coded chart-state observation used alongside the truthful clinical resource when legacy or source distinctions are not carried by that resource. Properties and values are vendor-neutral Dental Core semantics, not application field names. |
| Dental Clinical Provenance |
Provenance for dental clinical resources, including whether a final diagnosis or classification was derived or explicitly selected by a clinician. |
| Dental Device |
Dental or orthodontic device, component, or retained pin located at one or more FDI tooth positions and optionally linked to a parent prosthesis. |
| Dental Finding |
Country-neutral observed dental finding with patient, effective time, and optional FDI tooth and surface location. |
| Dental Gingival Assessment |
Method-qualified gingival assessment at one tooth. The result is a Fischer 2017 category, a direct UCUM millimetre measurement, or binary periodontal-probe transparency; these result forms are not silently converted. |
| Dental Gingival Recession Assessment |
Tooth-qualified gingival recession classification supporting Miller 1985 for existing records and Cairo 2011 as a distinct alternative. New surface-specific assessments should identify one surface; legacy odontogram records remain valid without one. |
| Dental Implant |
Manufacturer-neutral identity for a dental implant at one FDI position. Product details remain ordinary Device properties and issuer identifiers. |
| Dental Mesiodistal Tooth Width |
A measured mesiodistal tooth width with an explicit method. Image or document source evidence is optional for manual or cast measurements. |
| Dental Model Analysis Measurement |
A provider-neutral derived model-analysis result whose raw observation inputs remain explicit references. |
| Dental Model Analysis Panel |
A panel that groups atomic tooth-width or other model-analysis observations without embedding a named method or norm. |
| Dental Orthodontic Finding |
Observed tooth position, occlusion, appliance, retention, or model-analysis finding. Clinical values use applicable issuer terminology directly. |
| Dental Orthodontic Photograph |
A standardized orthodontic photograph used as exchangeable image evidence; the image content and acquisition protocol remain outside this profile. |
| Dental Peri-Implant Finding |
Site-qualified periodontal measurements and implant-specific indices around one referenced dental implant. |
| Dental Periapical Index |
Radiographic periapical index grade for one tooth. The grade is a reading of an image, so the source evidence is mandatory: a grade without its radiograph is not a reproducible measurement. |
| Dental Periodontal Finding |
Site-qualified periodontal measurements and findings for one tooth. LOINC and SNOMED CT are referenced directly for applicable observables. |
| Dental Periodontitis Condition |
Confirmed periodontitis diagnosis with stage, grade, and extent or distribution from the 2017 World Workshop classification. The final clinician-selected values are clinical facts; whether software derived or a clinician overrode them belongs in Provenance. |
| Dental Photostatic Analysis |
A panel that groups atomic photostatic measurements from standardized image evidence without embedding a named norm or algorithm. |
| Dental Photostatic Measurement |
A measurement derived from standardized orthodontic image evidence with an explicit method. |
| Dental Procedure |
Performed dental work with patient, occurrence, performer, and one or more FDI tooth positions. |
| Dental Pulp Diagnosis |
Pulpal diagnosis for one FDI position. The diagnosis is recorded independently of sensibility and percussion tests, which support but do not derive it. |
| Dental Radiographic Caries Depth |
Radiographic depth of a caries lesion on one tooth surface. The surface is the single FDI surface on bodySite; the radiograph may be referenced through derivedFrom. |
| Dental Restoration Evaluation |
Tooth- and surface-qualified evaluation of an existing restoration. The overall verdict is the FDI clinical evaluation score; observed defects and the resulting clinical action are separate axes so that a score is never inferred from a defect or an action from a score. |
| Dental Risk Evidence |
Structured patient-level evidence used in dental diagnosis or grading, including cigarette count, periodontitis-attributed tooth loss, and imaging-derived maximum bone-loss percentage. |
| Dental Service Request |
Requested dental intervention with explicit intent and FDI tooth location. |
| Dental Skeletal Maturity Assessment |
A panel that groups atomic skeletal maturity observations with explicit method and source evidence. |
| Dental Skeletal Maturity Observation |
An atomic skeletal maturity observation with explicit method and image or document source evidence. |
| Dental Target Chart State |
Desired or proposed tooth state linked to a plan request. Recorded extensions preserve target descriptions without asserting that the state is currently observed or that treatment occurred. |
| Dental Tooth State |
Structured observed state for one FDI position. Component codes identify structure; each component value is required from a Dental Core ValueSet with concrete codes. SNOMED CT may be sent as an additional coding. |
These define constraints on FHIR data types for systems conforming to this implementation guide.
| Periodontal Site |
Identifies the location around a tooth for a periodontal or peri-implant measurement without defining a local clinical terminology. |
| Periodontitis Extent and Distribution |
Localized, generalized, or molar-incisor pattern from the 2017 World Workshop periodontitis classification. |
| Periodontitis Grade |
Progression grade A through C from the 2017 World Workshop periodontitis classification. |
| Recorded Apical Finding State |
Preserves an unqualified target apical-finding description and its optional source root name as one assertion without inferring a diagnosis. |
| Recorded Bracket Surface |
Preserves the tooth surface recorded for a bracket using the issuer-owned FDI buccal or lingual code. It does not establish that a Device exists when carried on chart or target state. |
| Recorded Cantilever Pontic Role |
Preserves whether the source marked one tooth position as a cantilever pontic role. It does not establish that a Device exists or infer a bridge identity, supporting abutment, or support relationship. |
| Recorded Crown Fracture Description |
Preserves an unqualified crown-fracture description without asserting tissue depth, crown-root extent, severity, or equivalence to a clinical terminology concept. |
| Recorded Implant Position Description |
Preserves an unqualified description of an implant's schematic position within its FDI tooth site. The text is not a measurement or a coded anatomical location. |
| Recorded Orthodontic Progression Flag |
Preserves whether the source explicitly marked a tooth's orthodontic state as progressive. It does not classify the change as pathological or intended treatment movement. |
| Recorded Papilla Loss Grade |
Preserves one source-declared papilla-loss grade, its mesial or distal site, and the source's named classification attribution without publishing or claiming equivalence to a clinical scale terminology. |
| Recorded Root Endodontic State |
Preserves one unqualified target endodontic-state description with its optional source root name. Absence of a root denotes the separate whole-tooth fallback and never a distinct canal. |
| Recorded Root Fracture State |
Preserves an unqualified target root-fracture description and its optional source root name as one assertion without inferring a diagnosis. |
| Recorded Root Resection State |
Preserves an unqualified root-resection chart description and its optional source root name as one assertion. It does not assert that a procedure was performed, requested, or scheduled. |
| Restoration Renewal |
States whether a requested crown, bridge, or denture fitting renews an existing restoration of the same kind at the requested tooth positions. |
| Sub-tooth Location Detail |
Exact source text for a sub-tooth location when tooth, surface, and six-site periodontal position are insufficient and no admitted coded locator is available. |
| Tooth Position |
Identifies one permanent or primary tooth using ISO 3950 FDI notation when the containing resource has no bodySite element. |
| Tooth Surface |
Identifies one tooth surface with the issuer-owned HL7 Terminology FDI-surface CodeSystem. Repeat the extension for multiple surfaces. |

| Caries Findings |
Result of a DentalCariesFinding. The lesion surface is the FDI surface on bodySite; activity and ICDAS severity are separate components. Root caries is stated only by root-caries or cavitated-root-caries; a caries or secondary-caries result without a surface records a lesion whose surface was not recorded and is never read as root caries. |
| Caries Lesion Activity |
Active and arrested lesion activity. |
| Cervical Involvement Kinds |
What extends into the cervical region when a cervical-involvement finding names no tooth surface: a caries lesion or a direct filling. Such a finding states that the side was not recorded; it is never a root caries finding and never a surface of its own. |

Mild, moderate, and severe crowding categories. |
| Dental Chart Properties |
Properties admitted by DentalChartState. |

Endodontic state of the tooth or one of its roots, bound required on DentalToothState.component[rootEndodonticState]. Root-post type is a separate value from the canal filling; a combined post-and-filling value is not defined. |
| Skeletal Maturity Assessment Methods |
Methods admitted on a Dental Core skeletal maturity observation. |
| Tooth Mobility Grades |
Observed tooth mobility grade on DentalPeriodontalFinding.component[toothMobility]. Absence of mobility is not recorded as a grade. |

Reference-only canonical metadata for Cairo's 2011 gingival recession classification. The underlying expressions are not distributed in Dental Core. |
| Caries Lesion Activity |
Active versus arrested caries lesion activity, the axis orthogonal to ICDAS lesion severity. The identifiers are owner-authored because the ICDAS lesion activity assessment publishes criteria rather than a consumable code list; source wording is not distributed. |

| Crowding Severity |
Owner-authored categorical crowding severity used with a measured arch-length discrepancy. Source wording is not distributed. |
| Dental Chart Property |
Vendor-neutral properties needed to preserve clinically reviewed dental chart state when the primary FHIR resource does not retain the original distinction. |
| Dental Chart Value |
Owner-authored Dental Core values for tooth state, chart findings, and chart properties. Dental Core owns these primary codes; SNOMED CT equivalents, where they exist, are stated only in the ConceptMap dental-chart-value-to-snomed-ct (ADR-002). Codes do not claim equivalence to issuer terminology by themselves. |
| Dental Observation Component |
Structural component identifiers for Dental Core observation slices. Component values carry clinical meaning in applicable external terminology or primitive FHIR values. |
| Dental Provenance Activity |
Activities distinguishing software-derived clinical output from explicit clinician selection. |

Reference-only canonical metadata for the FDI World Dental Federation clinical evaluation score for restorations. The underlying expressions are not distributed in Dental Core. |
| FDI Tooth Position |
FHIR coding namespace for permanent and primary tooth positions expressed in ISO 3950 two-digit notation. This is a structural locator, not a replacement for a clinical terminology. |
| Fischer 2017 Three-Level Gingival Phenotype |
Reference-only canonical metadata for the Fischer 2017 double-ended periodontal-probe classification. The underlying expressions are not distributed in Dental Core. |
| Gingival Assessment Method |

| Miller Gingival Recession Classification 1985 |
Reference-only canonical metadata for Miller's 1985 gingival recession classification. The underlying expressions are not distributed in Dental Core. |
| Restoration Action |
Clinical consequence drawn from a restoration evaluation. The identifiers are owner-authored because the FDI criteria publish action tiers rather than a consumable code list; source wording is not distributed. |
| Restoration Defect Type |
Defect axes assessed on an existing restoration. The identifiers are owner-authored because the FDI criteria publish evaluation dimensions rather than a consumable code list; source wording is not distributed. |
| Skeletal Maturity Assessment Method |
Named methods that establish skeletal maturity from radiographic evidence. The identifiers are owner-authored because no issuer publishes a consumable code list for the method axis; source wording is not distributed. |
| Ørstavik Periapical Index 1986 |
Reference-only canonical metadata for the Ørstavik periapical index. The underlying expressions are not distributed in Dental Core. |
These define transformations to convert between codes by systems conforming with this implementation guide.
| Dental Chart Value to SNOMED CT |
Relates the Dental Core tooth-state and chart-finding value codes to SNOMED CT. A code is equivalent only where an active SNOMED CT concept with the same clinical meaning was verified; every other code is listed as unmatched. Dental Core codes remain the primary coding. |
