Define as...
The progressive loss of tooth mineral, followed by bacterial invasion into the demineralized tooth.
Usually occur in....
1.pit and fissue: develop initially in the fissures of the teeth, but can spread into the dentine, causing complete breakdown of the tooth
2. smooth surface: most common on the interdental surfaces, but can occur on any smooth surface of the tooth; enamel is gradually broken down and an open cavity is formed
3. cemental: involves the cementum of a tooth
What is...
1. recurent: caries that arise around an exisiting retoration due to an alteration in the integrity of the resotration
2.acute (rampant): dental caries that involve several teeth, appear suddenly, and often progress rapidly
3. chronic: dental caries progressing slowly over time in several teeth
4. enamel caries: caries that involves the enamel of a tooth
5. dentin caries: caries that spreads along the dentinoenamel junction and involves dentinal tubules, eventually reaching the pulp
Clinical Features:
any gender or age
toothache; sensitivity to hot or cold food or drinks
chalky white deposit in enamel surface of tooth, visible pits, or holes in the teeth
brown yellowish cavitation of the teeth
surface of the tooth may be soft
Radiographic Features:
may show some cavities early
Etiology:
multifaceted: saliva, microflora, diet
Tissue of Origin:
enamel, dentin
Main Pathologic Process:
inflammation
Treatment:
1.changing the microflora, using agents such as topical chlorhexidine and topical fluoride
2.reducing the amount of dietary sucrose
3.decreasing the frequency of eating
4.adding fluoride, particularly through daily tooth brushing
5.increasing salivary flow, using mechanical stimulation during vigorous chewing or by using drugs
Prognosis:
good when diagnostic tests show that the disease is no longer active and the risk is low
untreated the dental decay my lead to a dental abscess
