Applied Basic Sciences: Anatomy, Physiology, Microbiology
Core concepts
Apply basic science to clinical situations. Know dental anatomy: tooth numbering, eruption timelines, and tooth morphology. Understand head and neck anatomy relevant to injections and surgery, including nerves, vessels, and salivary glands. Learn oral physiology: saliva, plaque formation, and the caries process. Microbiology covers normal oral flora, pathogens, biofilm, and the infectious diseases relevant to practice. Also understand systemic conditions that affect dental care, such as diabetes and cardiovascular disease, and how they alter treatment planning.
Traps to watch
Questions test applied knowledge, not memorized lists. A trap is confusing deciduous and permanent eruption timelines, or misidentifying which nerve supplies which region. Another trap is assuming all oral bacteria are harmful - normal flora are part of health, while dysbiosis drives disease. Microbiology traps involve transmission routes and the difference between colonization and infection. Systemic-disease traps involve timing: elective care may be deferred during uncontrolled disease.
Worked rule of thumb
Link structure to function to clinical consequence. Example: the caries process requires a susceptible tooth, fermentable carbohydrates, cariogenic bacteria, and time - remove any factor and the risk falls, which is why diet and fluoride counseling matter.
Integration
Connect anatomy and microbiology to infection control and treatment planning for exam scenarios.
