CariesBitewing Film primarilyPeriapical film also usedLow kVp, high contrast (short scale)
Proximal caries susceptible zone cariesApproximately 50 % demineralization is required forradiographic detection of a lesion.The thickness of the tooth buccolingually masks thecarious lesion when it is small.The actual depth of penetration of a carious lesion isdeeper clinically than radiographically.
Root caries may be confused with cervical burnoutCervical burnout appears as a collar or wedge-shaped radiolucency on themesial and distal root surfaces near the CEJ of a tooth. The tissue density at the cervical region of the tooth is less than the regionsabove and below it. (variable penetration of X-ray)Burn-Out:*Mainly located at the neck of the tooth (Demarcated aboveby enamel cap or restoration and below by the alveolarbone)**Usually all teeth are affected esp. smaller premolars.***it is more obvious when the exposure factors areincreased!
Anterior Cervical Burnout bone level cervical burnout area
Cervical burnoutRadiolucency seen above left (arrow) disappears onperiapical film of same tooth (above right).
Cervical burnout in theanterior region due to gapbetween enamel (redarrows) and alveolar boneover root.
Recurrent CariesMay be due to high caries rate, poororal hygiene, failure to remove all thecaries, defective restoration or acombination.
Recurrent Caries Is not always easy to detect radiographically:1. Location of caries lesion relative to restoration.2. Angulation of X-ray beam.
