#### C.8.11.9 Intra-Oral Image Module

Table C.8-76 contains IOD Attributes that describe a Digital Intra-Oral X-Ray Image including its acquisition and positioning.

Table C.8-76. Intra-Oral Image Module Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Positioner Type | (0018,1508) | 1 | Enumerated Values: NONE CEPHALOSTAT RIGID
Image Laterality | (0020,0062) | 1 | Laterality of the region examined. Enumerated Values: R right L left B both (i.e., midline)
Anatomic Region Sequence | (0008,2218) | 1 | Sequence that identifies the anatomic region of interest in this image. Only a single Item shall be included in this Sequence.
>Include Table 8.8-1 “Code Sequence Macro Attributes” . | Defined CID 4016 “Anatomic Region for Intra-oral Radiography”.
>Anatomic Region Modifier Sequence | (0008,2220) | 1C | Sequence that refines the anatomic region of interest in this image. Required if Primary Anatomic Structure Sequence (0008,2228) is not sent. Only a single Item shall be included in this Sequence.
>>Include Table 8.8-1 “Code Sequence Macro Attributes” | Defined CID 4017 “Anatomic Region Modifier for Intra-oral Radiography”.
Primary Anatomic Structure Sequence | (0008,2228) | 1C | Sequence that describes the primary anatomic structures of interest in this image. See Section C.8.11.9.1.1 for further explanation. Required if Anatomic Region Modifier Sequence (0008,2220) is not sent. One or more Items shall be included in this Sequence.
>Include Table 8.8-1 “Code Sequence Macro Attributes” . | Defined CID 4018 “Primary Anatomic Structure for Intra-oral Radiography (permanent Dentition - Designation of Teeth)” or CID 4019 “Primary Anatomic Structure for Intra-oral Radiography (Deciduous Dentition - Designation of Teeth)”. See Section C.8.11.9.1.1 for further explanation.

##### C.8.11.9.1 Intra-Oral Image Attribute Descriptions

###### C.8.11.9.1.1 Primary Anatomic Structure Sequence

Code Value (0008,0100) shall be drawn from the DICOM Content Mapping Resource, CID 4018 “Primary Anatomic Structure for Intra-oral Radiography (permanent Dentition - Designation of Teeth)”, for permanent dentition, or CID 4019 “Primary Anatomic Structure for Intra-oral Radiography (Deciduous Dentition - Designation of Teeth)” for deciduous dentition.

These Context Groups correspond to ISO 3950-1984 that describes a designation of permanent and deciduous dentition using a two digit code, the first digit of which designates a quadrant, and the second digit a tooth.

The teeth imaged shall be listed as multiple Items in the Primary Anatomic Structure Sequence (0008,2228).
