It includes the host, agent, environment and time. The host factors include the teeth and saliva. The agent factors include the micro organisms. The environment factors include the substrate factors. The composition, position and morphological factors are included under the teeth. The composition, Ph, quantity, anti bacterial factors and its ability to flow are included under the saliva. Other factors could be age, sex, race, diet and dental plaque.
The inorganic contents of teeth are quite common in the enamel. It is followed by dentin and cementum. The organic contents of teeth are quite common in the cementum. It is followed by dentin and enamel.
The shape of tooth plays an important role in the initiation of caries. The deep narrow pit and fissures are the starting point of caries in most of the teeth. If the tooth area is more than the chances of caries will be more. As the narrow pit and fissures allow the food particles to trap and so does the bacteria which may start the caries.
Teeth which are not in the alignment and have a difficulty in the cleaning have the ability to get food deposits collected. It allows the caries to develop.
The composition of saliva includes the organic, inorganic components. The inorganic components include the calcium, hydrogen and magnesium ions. These are positive ions. The other ions are chlorine, fluorine and phosphate. These are negative ions.
The organic components include the carbohydrates, lipids, oxidase, protease, enzymes and proteins which may or may not contain nitrogen.
The ph of saliva includes the bicarbonate ions. The ph of saliva increases with the flow rate. There are few buffers which increase the ph of saliva and include the ammonia, urea etc. These buffer ions are not present on each and every tooth surface.
The quantity of saliva includes the normal production of saliva. It is around 750 ml per day. In the xerostomia and the non existence of salivary gland there is a decrease or no flow of saliva. It can lead to increase in the rate of caries.
The ability of saliva to flow includes the viscosity rate which does not have much significance in relation to dental caries. The patients with thin and water like saliva have a large caries rate. But the patients with thick saliva have low caries rate.
The anti bacterial property of saliva includes the lysozyme, lacto peroxidase and immunoglobin A.
The race includes that the people of china and American African have a low caries rate as compared to the other groups. This could be due to the differences in socio economic as well as cultural factors. Moreover, the people in India have less chances of caries as compared to the European people.
The age includes the young adolescent age group only. The 12 year old are known as the global indicators of dental caries.
The sex includes the males as well as females. The male patients have a less chances of caries as compared to the female patients.
