Interpretasi Radiografi yang Bisa Digunakan:

1. Bitewing Film

2. Periapical film

3. Panoramic (terbatas)

Karies proses demineralisasi radiolusensi



Radiographs is used to aid detection of carious

lesions.Advanced carious lesions of the occlusal, cervikal

and other exposed portions of a tooth are notdifficult to diagnose by clinical examination.

The purpose of a radiograph, therefore, is todiagnose early carious lesions or those which liehidden under restorations, or in theinterproximal areas and to know the extent ofthe carious lesion.



I

M = Moderate (Stage II)

I = Incipient (Stage I)

A = Advanced (Stage III)

S = Severe (Stage IV)

Caries Classification

S

AMA



IncipientModerate

Advanced



Interproximal Caries(Incipient)

I

Up to half the thickness of enamel

Usually not restored unless patienthas high level of caries activity (high

risk). Treat with fluoride.



The arrow points to incipient lesion onthe distal #10



M

Interproximal Caries

(Moderate)

More than halfway through theenamel (up to DEJ)



The bottom arrow points to a moderate lesion onthe distal of # 20. The upper arrow points to one ofseveral incipient lesions on the molar and

premolars.



AA


(Advanced)



Advanced lesion identified by arrows.



Advanced lesion



More than halfwaythrough the dentin

S


(Severe)



Severe lesion



Occlusal Caries

Must have penetrated into dentin

Diagnosed from clinical exam

May be seen as thin radiolucent line orcup-shaped zone underlying occlusalenamel, but difficult to see on

radiographs unless lesion is large.



Occlusal caries



Buccal/Lingual Caries

Should be identified from clinical exam.

On a dental radiograph, caries that involvesthe buccal or lingual surface will appear as a

small, circular radiolucency in middle oftooth , although it is not very radiolucent.

In order to determine the location of thelesion, a clinical examination with an

explorer is necessary.Depth can not be determined

radiographically.



Lingual caries (Can’t tell whether it’s buccal

or lingual from one radiograph



Buccal caries with severe interproximal

caries on # 12



Root Caries

On a dental radiograph, root surfacecaries appear as a cupped-out or crater-shaped radiolucency just below the

cemento-enamel juction (CEJ). Earlylesions may be difficult to detect on adental radiograph.

Usually found on older individuals withprominent recession and/or periodontitis.

May have xerostomia due to medications.May be confused with cervical burnout.



Root caries



Recurrent Caries

Radiolucency extends into the dentin(with/without extends to pulp) adjacent toan existing restoration.

May be due to unusual susceptibility tocaries, poor oral hygiene, failure to removeall of the caries during cavity preparation,a defective restoration or a combination of

the above.
