(a)  

Caries balance is illustrated in terms of (a)   factors, for those favoring demineralization

Caries balance is illustrated in terms of (a)   factors, for those favoring remineralization

In a healthy person, the microbiome is in (a)  

Microorganism coexist in a (a)   balance

with beneficial bacteria keeping harmful bacteria in check and preventing them to become (a)   .

(a)   of oral microbiome, lead to overgrowth of harmful bacteria

dental caries activity is characterized by localized (a)   and loss of tooth structure

Some bacteria in the biofilm metabolize refined (a)  

Some bacteria in the biofilm metabolizes refined carbohydrates for energy and produce organic (a)  

Organic acids, if present in the biofilm ecosystem for extended periods, can (a)   in the biofilm

Organic acids if present in the biofilm ecosystem for extended perids can lower the pH in the biofilm to below a critical level (5.5 for ____, 6.2 for ______) use ","

(a)  

With extended periods of low pH, there is a shift inthe microbiome to bacteria that are ______ and _____, causing ________ in the mircobiome. use ","

(a)  

The low pH drives ______ and ______ phosphate from the tooth. use ","

(a)  

The low pH drives calcium and phosphate from the tooth to the biofilm in an attempt to reach equilibrium, hence resulting in the a net loss of minerals by the tooth or (a)   .

When the pH in the biofilm returns to _______ and the concentration of soluble calcium and phosphate is supersaturated relative tot htat in the tooth, the mineral can then be added back to partially demineralized enamel in a process called _______________. use ","

(a)  

Dental caries lesions result from a ______ process of damage (demineralization) and _________ (remineralization) of the tooth matter.

(a)  

Take place several times a day over the life of the tooth and are ________ by many factors, these factors are highly _________ and ________-specific and will differ from person to person

Said that organic portion of the tooth serves as pathways for advancing mircroorganism causing ___________ of the teeth and therefore dental caries. ________Theory

(a)  

(Proteolytic Theory) Suggested that the initial lesion of the carious process is dues to the _____________ attacking the lamellae, rod sheath, tufts and walls of tubules. Believed that the yellow pigmentation characteristic of caries was produced by proteolytic organism (_________).

(a)  

(Proteolytic Theory). Proposed that the first step in the carious process is the breakdown of dental ___________. Nasmyth's membrane and enamel proties are acted upon by ________ enzyme producing sulfuric acid. This acid plus the calcium of hydroxyapatite crystals destroys the __________ components of enamel.
