Prelims Cario Flashcards
Deal with understanding dental caries, its etiology, pathogenesis and sequelae
Cariology
Study and analysis of the distribution (who, when and where) patterns and determinants of health and disease conditions in defined populations.
Epidemiology
Cornerstone of public health, and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare
Epidemiology
Measures the probability of occurrence of a given medical condition in a population within a specified period of time
Incidence
Expressed simply as he number of new cases during some time period
Incidence
proportion of a particular population found to be affected by a medical condition at a specific time
Prevelance
Derived by comparing the number of people found to have the condition with the total number of peolpe
Prevelance
What are dental caries?
Complex disease caused by a physiologucal imbalance between fluid and mineral dental structures
Mechanism of dental caries
From the fermentation of carbohydrates, the bacteria produced organic acids such as lactic acid, the formic, acetic and propionic which penetrate the dental tissues, dissolving the enamel dentin and cementum and may cause cavitation
How many estimated people are affected by caries of permanent teeth?
2.3 billion people
how many children suffers from caries of primary teeth
530 million
Reasons for the decline of caries
Fluoridation of water supplies
Use of fluoride supplements
Use of fluoride dentrifices
Availability of dental resources
Increased denta awareness
Changes in diagnostic criteria
Decrease in sugar consumption
Reason for the rise in caries
Increase in sugar consumption in underdeveloped countries
Lack of dental resources
Socio-economic factors
Lack of water fluoridation
Lack of preventive dental health programs
Hard tissues of the teeth
Enamel, dentin, alveolar bone, cementum
