|
Phases of "Plaque Formation" |
Phase 1: Molecular adsortion to condition the biofilm formation Phase 2: Bacterial adhesion by single organism Phase 3: Growth of extracellular matrix production and multiplication of the adhering bacteria Phase 4: Sequential adsortion go further bacteria to form a more complex and mature biofilm |
|
|
Phases of plaque formation... Phase 1: Molecular adsortion to condition the biofilm formation |
-Providing the primary site for bacterial attachment
-Acquired pellicle that can bonded with Salivary Glycoproteins and Antibodies the help microbial attachment |
|
|
Phases of plaque formation... Phase 2: Bacterial adhesion by single organism
|
-Specific attachment structure
-Prolonged exposure |
|
|
Phases of plaque formation... Phase 3: Growth of extracellular matrix production and multiplication of the adhering bacteria |
Increasing thickness of the bacterian |
|
|
Phases of plaque formation... Phase 4: Sequential adsortion go further bacteria to form a more complex and mature biofilm |
-Poor diffusion of oxygen
-Anaerobic Condition in the deepest layers
-Facilitates the adherence of more complex and dangerous bacteria flora |
|
|
The primary bacteria colonization within 24 hours ... |
-Mainly Streptococci Sanguis
-Also found Actinomyces spp |
|
|
The second stage of bacteria colonization ... |
Mainly Actinomyces spp |
|
|
Biofilm Structures |
-Bacterias cluster together
-Each microcolony is an independant community -Fluid channels
- Chemical signals allow communication between the microcolonies (Quorum Sensum) |
|
|
Supragingival Calculus |
-Creamy-whitish to dark yellow of moderate hardness
-Adjacent to excretion ducts of major salivary glands (lg lower anteriors/ vb upper molars)
-Visible |
|
|
Subgingival Calculus |
-Brownish to black hard mass with rough surface
-In periodontal pocket
-May be seen in XR or by tactile exploration with periodontal probe |
|
|
_______ calculus represents a secondary product of infection and not a primary cause of periodontitis |
Subgingival |
