What is Colonization?
Colonization is the establishment of bacteria or other microorganisms in a living host. Permanent colonization in a symbiotic relationship with the host results in the establishment of normal oral flora. These organisms participate in many beneficial relationships. However, some can be considered opportunistic pathogens.
Types of Bacteria in Root Canals
- Aerobic (coronal)
- Facultative anaerobic (coronal to mid-root)
- Gram-negative obligated
Understanding Trophic Levels, Food Chains, and Energy Flow in Ecosystems
Trophic Levels in Ecosystems
A trophic level consists of all the organisms in an ecosystem that feed in the same way. There are three main types:
Producers
Autotrophic organisms that perform photosynthesis and use solar energy to transform inorganic matter into organic matter.
Consumers
Heterotrophic organisms that eat other living things:
- Primary consumers: Feed on producers; they are herbivores (e.g., rabbits, deer).
- Secondary consumers: Feed on primary consumers (e.g., frogs feed on insects).
- Tertiary
Understanding Cell Biology: Structure, Function, and Processes
General Properties and Types of Cells
Cell Theory
- All organisms are made of cells.
- The cell is the fundamental unit of life.
- Cells come from pre-existing cells.
What is a Cell?
- Contains a stable blueprint of information (DNA).
- Has a discrete boundary separating the cell interior from the environment (cell membrane).
- Ability to harness material and energy from the environment.
- Able to read and interpret instructions (DNA).
The Central Dogma of Molecular Biology
- Describes the basic flow of information in a cell.
Periodontitis Treatment: Antibiotics, Local Delivery Systems, and Prognosis
- Chemotherapeutic agent: a general term for a chemical substance that provides a clinical therapeutic benefit.
- Antiinfective agent: a chemotherapeutic agent that works by reducing the number of bacteria present.
- Antibiotic: a naturally occurring, semisynthetic, or synthetic type of anti-infective agent that destroys or inhibits the growth of selective microorganisms, generally at a low concentration.
- Guidelines for use of Antibiotics in Periodontal Therapy:
- Clinical diagnosis and situation will determine
