• functional limitations, and higher risk for hospitalization,
• nutrition & sleep disruption.
• developmental patterns by such phenomena as obesity and decreased body height.

CURRENT TRENDS IN CARIES INCIDENCE

• In developed countries, caries prevalence declined in last decade, causes are multifactorial. Eg: communal water fluoridation.
• In developing countries increase in caries prevalence, cause is increased use of refined carbohydrates.

CARIES SUSCEPTIBILITY JAW QUADRANTS

• Maxillary teeth more susceptible than mandibular arch

 relate to gravity and saliva, with its buffering action, would tends to drain from upper teeth and collect around lower teeth.

• Teeth farthest back in the mouth are more frequently carious.
• Caries susceptibility of individual tooth surface

occlusal > mesial > buccal > lingual

• Etiologic factors in dental caries:
• 1.the host (teeth, salive)
• 2.microflora.
• 3.substrate(diet).
• 4.time..
