Tooth anatomy on xray

Panoramic X-rays
A panoramic dental X-ray shows all of the structures in your mouth on a single image, including your upper and lower teeth, jaw joints, nerves, sinuses and supporting bone.

As a result, the radiographic appearance of tooth enamel is light. The dentin is less dense and less radiopaque than the enamel. The dental pulp appears dark or radiolucent. Figure 15.6 illustrates varying hard tissue radiopacities.

Radiographic appearance The teeth are well visualized on these modalities ¹^-³: enamel: most radiopaque part, hardest tissue in the human body. dentin and cementum are less radiopaque than the enamel and are indistinguishable on these modalities. pulp chamber and root canal are lucent and positioned centrally.

Gross Anatomy

There are twenty deciduous (primary) teethin young children, with ten per jaw and five in each quadrant, which consist of (distal to mesial): 1

Arterial Supply

Arterial supply to the teeth is derived from the maxillary artery, a branch of the external carotid artery, via the: 1. superior alveolar arteries 1.1

Venous Drainage

Venous drainage of the teeth is into either the: 1. pterygoid venous plexus, or 2. facial vein via vessels that generally follow the arteries

Innervation

1. the maxillary teeth are supplied by a group of superior alveolar branche… 2

Variant Anatomy

1. hyperdontia: supernumerary teeth 2

Radiographic Appearance

The teeth are well visualized on these modalities 1-3: 1. enamel: most radiopaque part, hardest tissue in the human body 2

Related Pathology

1. edentulism 2. dental (periapical) abscess 3

How to read dental X-rays?

The first step in reading how to read dental X-rays is to understand the anatomy that is visible on the film

The crown of the tooth, the portion that is visible in the mouth, is represented by a white area on the X-ray

The root of the tooth, which is embedded in the jawbone, is represented by a darker area

X-rays, also known as radiographs, are an essential part of any dental care treatment plan. They are diagnostic, but they can also be preventive, by helping a dentist diagnose potential oral care issues in a patient’s mouth before they become a major problem.Plain radiograph/OPG/CT The teeth are well visualized on these modalities 1-3: enamel: most radiopaque part, hardest tissue in the human body dentin and cementum are less radiopaque than the enamel and are indistinguishable on these modalities pulp chamber and root canal are lucent and positioned centrally
