reversed by a rigorous preventive programme. But this depends on adequate early
diagnosis. While several techniques for caries diagnosis have been introduced
recently, most notable of which is Diagnodent (KAVO), bitewing (BW) radiography
is by far the most acceptable and widely available for use in general practice.
Radiographs should form a routine part of any dental examination and it is necessary
to repeat radiographs for dental caries diagnosis at suitable intervals. The intervals
that are appropriate to children vary according to the level of caries that a child
presents with. After an initial examination and BW radiographs a second series should
be taken within 1 year if the child is caries free but at 6 months if this is active caries.
Once it has been established that a child remains caries free, then, the interval
between BWs can be increased to 24 months or even longer. However, if active caries
remains a problem, then 6 monthly intervals between BWs are necessary.


Key Point
Destruction by caries of the marginal ridge of a primary molar indicates likely pulpal
involvement.
