Refers to Which part of the tooth will be infected or be affected by dental carries and how will it progress | Histopathology |
Caries is an infectious microbiologic disease of the teeth that results in localized ________________________________ of the calcified tissues | Dissolution and destruction |
Refers to how it is not only caused by the presence of microorganisms but many factors that interplay together | Multifactorial |
Spell out IADR | International Association for Dental Research |
There may be times of demineralization but given treatment there would be remineralization | Phasic demineralization and remineralization |
Its balance is responsible for the initiation and progress of dental caries | Phasic demineralization and remineralization |
Pathological and protective factors: Imbalance / shifting where pathologic factors are heavier | Caries |
With all of these definition there is one thing that is always emphasized | Biofilm-mediated or microbiological |
There is always the presence of __________ which play in the formation of dental caries | Microorganisms |
According to ___________ Dental caries is a preventable, chronic, and biofiIm-mediated disease modulated by diet. | Sturdevant‘s Art and Science of Operative Dentistry 7th ed |
According to ___________ Dental caries is caused primarily by an imbalance of the oral flora (biofilm) due to the presence of fermentable dietary carbohydrates on the tooth surface over time. | Sturdevant‘s Art and Science of Operative Dentistry 7th ed |
Primary food of bacteria | Carbohydrates |
Agents that let the dental plaque be seen | Disclosing agent |
Progression of biofilm | Acquired pellicle → material alba → dental plaque → calcular deposit |
What will be seen in association | Acquired pellicle |
30mins - 1hour after brushing __________forms | Acquired pellicle |
Has the ability to attach themselves in those surfaces with acquired pellicle or food debris | Actinomyces |
Bacteria progression | Actinomyces → corynebacterium → streptoccocus |
From adhesion there is now | Proliferation |
How does bacteria proliferate | Food (carbohydrates) |
Collection of group of microorganisms | Microcolonies |
STAGES OF BIOFILM FORMATION: Formed in 1-3 weeks | Microcolonies |
STAGES OF BIOFILM FORMATION: occurs after formation of microcolonies | Biofilm formation |
Will always cause acid formation | Bacterial activity |
STAGES OF BIOFILM FORMATION: Bacteria and their byproducts | Growth "maturation" |
Diet high in sugar causes the appearance of ________________ in mouth using sugar as energy source; as the bacteria consumes sugar | Mutans Streptococci |
Byproduct of Mutans Streptococci | Lactic acid |
Damage to inorganic substances | Demineralization |
Damage to organic substances | Dissolution |
Causes demineralization | Acidic environment |
Susceptible Tooth Surface | Pits and fissures, proximal areas below contact area, cervical third |
Describe the clinical appearance of initial caries formation | White spot lesion |
What are the cariogenic microorganisms | Mutans Streptococci, lactobacillus acidophilus |
Process where minerals are lost | Demineralization |
Initiation of dental carries | Chalky white appearance |
Capable of producing caries because of their acid formation | Cariogenic organisms |
Seen on the initial stage of dental carries | Streptococcus mutans |
Degree to which a tooth is likely to become carious | Carcinogenicity potential |
Possibility of having caries | Carcinogenicity potential |
What specific part/ structure of tooth is demineralized? | Inorganic portion |
Area where there is drop in pH | Biofilm-tooth interface |
Clinical manifestation of bacteria | Dental biofilm |
Clinical manifestation of dental biofilm | Gel-like matrix |
Chelation process affects what specific structure/ substance of tooth | Inorganic substances |
Chelation is carried out by | Soluble chelates, microorganisms + organic substances, Sulfuric acid |
Proteolysis is carried out by | Hydrolytic enzymes |
In Millers Theory, caries is caused by | Acidogenic bacteria |
Microorganisms mostly found in lesions | Lactobacillus acidophilus |
