L5-1 Dantal caries Classification
ACCORDING TO THE LOCATION AND SIZE
ACCORDING TO THE DEGREE OF ACTIVITY:
inactive or arrested
A caries lesion that is considered to be biologically inactive at the time of examination, that is, in which tooth demineralization caused by caries may have happened in the past but has stopped and is currently stalled.
black or brown shiny, hard dentin surface.
present even on non- susceptible areas such as buccal and lingual surfaces.
baby bottle caries, radiation therapy caries.
rapidly evolving caries affecting multiple teeth simultaneously.
usually light-colored cavities.
if left untreated, the lesion progresses indefinitely.
the majority of caries are active caries.
the progress depends on multiple factors:
environmental: diet, hygiene, fluoride exposure
dental: type of dentin, ability to protect the pulp
ACCORDING TO THE STAGE OF DEVELOPMENT:
when enamel has collapsed.
a cavitated lesion is usually an active one. active lesions normally retain plaque.
the presence of active lesions in a patient is one of the most important parameters to determine caries-risk in the future
with pulp exposure
very advanced caries can lead to pulp exposure.
if the pulp remains vital a pulp polyp g may form, however normally the pulp is already necrotic by then and what is exposed is the pulp chamber.
non-cavitated, with dentin involvement
dentin is involved but enamel is still intact
with coronal destruction
normally the pulp is necrotic.
in young patients or slow- evolving caries the crown may be destroyed but the pulp vitality is maintained.
it corresponds to a sub-surface enamel demineralization with a remineralization of the surface.
only visible when the tooth is dried.
the first visible clinical manifestation of caries.
the dentin may be affected already.
ACCORDING TO THE EMERGENCE
Secondary or recurrent caries:
Caries lesion located on a dental tissue adjacent to a previous restoration
Unremoved caries lesion left beneath the restorative material when filling a cavity. / Neglect or intention.
Caries lesion located on a dental surface that has not been treated previously and not adjacent to previous restorations
according to the location
incipient lesions on posteriors can only be seen on radiographs.
on anteriors the lesions can be seen directly or through enamel when the lesion is advanced.
the most frequent location of enamel caries
buccal and lingual surfaces: free smooth surfaces
it is rare to find caries on the free smooth surface of enamel.
if present, they are usually found on the gingival third: self-cleaning decreases
buccal: generally due to gingival recession.
proximal: under fillings, poorly-adjusted crowns, contact point loss, etc
pits and fissures
caries begins within these anatomical structures.
at first it is not easily distinguished from pigmentation
coronal caries (these anatomical features are only present on the crown):
buccal groove on mandibular molars
carabelli on maxillary molars
usually occlusal surfaces
it may seem small until the enamel breaks: despite having a large dentinal affectation.
