How is the histopathology of caries in enamel and dentine?

The histopathology of caries varies in pre-cavitated and post-cavitated lesions Enamel caries tends to occur on smooth surfaces or pits/fissures Pre-cavitated enamel lesions are composed of 4 zones – translucent zone, dark zone, body of lesion and surface zone

How does the microbiology of dental caries work?

Microbiota of dental caries Dental caries happens mainly when the production of organic acid results in dental hard tissue decalcification. Thus, dental caries bacteria should be acid-tolerant in carrying out the dental caries process in an acidic environment. [17] Acidogenic bacteria, e.g. S. mutans, are able to function at pH 6 and can carry out

When do caries in the primary dentition begin?

ECC can be a particularly virulent form of caries, beginning soon after dental eruption, developing on smooth surfaces, progressing rapidly, and having a lasting detrimental impact on the dentition. Children experiencing caries as infants or toddlers have a much greater probability of subsequent caries in both the primary

What happens to your teeth when you have a caries?

Dental caries is a biofilm-mediated, sugar-driven, multifactorial, dynamic disease that results in the phasic demineralization and remineralization of dental hard tissues. Caries can occur throughout life, both in primary and permanent dentitions, and can damage the tooth crown and, in later life, exposed root surfaces.

What are the clinical features of incipient caries?

INCIPIENT CARIES  The early caries lesion, best seen on the smooth surface of teeth, is visible as a ‘white spot’.  Histologically the lesion has an apparently intact surface layer overlying subsurface demineralization.  Significantly may such lesion can undergo remineralization and thus the lesion is not an indication for restorative treatment

What are the different types of enamel caries?

Ground section demonstrating smooth surface enamel caries – apex extending towards the ADJ. Credit to Dr Nurul Islam. Appearance – commonly sticky brown/yellow lesions, may be chalky white lesions A conical lesion with the base towards the ADJ – the opposite of smooth surface, with the caries following the enamel rods
