Carious lesions can be classified in different ways; this section introduces and
defines this terminology.
Lesions can be classified according to their anatomical site. Thus lesions
may be found in pits and fissures or on smooth surfaces. Lesions may
start on enamel (enamel caries) or on exposed root cementum and dentine
(root caries).
Primary caries denotes lesions on unrestored surfaces. Lesions developing
adjacent to fillings are referred to as either recurrent or secondary
caries. Residual caries is demineralized tissue left in place before a filling is
placed.
Carious lesions may also be classified according to their activity. A progressive
lesion is described as an active carious lesion (Figure 1.1) whereas
a lesion that may have formed earlier and then stopped is referred to as
an arrested or inactive carious lesion (Figure 1.7, 1.8). This concept of
activity is very important as it impinges directly on management because
active lesions require active management. However, the distinction between
active and arrested may not be straightforward. There will be a continuum of

changes between active and arrested, and part of a lesion may be active while
another part is arrested. This concept is totally logical because the lesion
merely reflects the ecological balance in the overlying biofilm.
Different teeth and surfaces are involved, depending on the area of plaque
stagnation and the severity of the carious challenge. Thus, with a very mild
challenge only the most vulnerable teeth and surfaces are attacked, such
as the cervical margin of the teeth or the occlusal pits and fissures of
permanent molars. A moderate challenge may also involve the approximal
surfaces of posterior teeth. A severe challenge will cause the anterior teeth,
which normally remain caries-free, also to become carious.
Rampant caries is the name given to multiple active carious lesions
occurring in the same patient, frequently involving surfaces of teeth that are
usually caries-free. It may be seen in the permanent dentition of teenagers
and is usually due to poor oral hygiene and taking frequent cariogenic snacks
and sweet drinks between meals (Figure 1.9a–c). It is also seen in mouths
