Public Health Dentistry
Primary prevention involves intervening before a lesion occurs to
prevent the disease from developing. This includes actions like brushing with
fluoride toothpaste, using fluoride mouth rinses, and maintaining a balanced
diet to prevent dental caries.

Dental Materials
Microfilled composites contain very fine silica particles (0.04 to 0.2 µm in diameter), which give them excellent translucency and a high surface area for better filling of small restorations.

Oral SurgeryStreptomycin is considered a narrow-spectrum antibiotic, primarily effective against Gram-negative bacteria and Mycobacterium tuberculosis. Ampicillin, chloramphenicol, and tetracycline are all classified as broad-spectrum antibiotics because they are effective against a wide range of both Gram-positive and Gram-negative bacteria.

Prosthodontics
When a tooth has been out of function for an extended period, it can experience changes in the periodontal ligament that supports it. The periodontal ligament is a fibrous connective tissue that connects the tooth to the bone and allows for a certain degree of movement. This movement is essential for the health of the ligament and the surrounding tissues. When a tooth is no longer subjected to the normal forces of biting and chewing, the periodontal ligament fibres can become weak or atrophied.
When this tooth is then used as an abutment for a fixed partial denture (FPD), it is once again exposed to the functional stresses that were previously absent. These stresses can cause traction on the periodontal ligament fibres, leading to pain and discomfort. The pain is mainly due to the sudden reintroduction of forces to the ligament that it is not accustomed to handling.

Oral PathologyHemophilia A is primarily due to deficiency of Factor VIII, and Hemophilia B is due to Factor IX deficiency. These are inherited X-linked genetic disorders caused by mutations in the F8 or F9 genes respectively. Classical hemophilia is not due to autoimmune mechanisms, though acquired hemophilia (rare) can involve autoantibodies against Factor VIII. Prothrombin deficiency and Vitamin K deficiency cause different coagulation disorders.

Oral PathologyEagles syndrome causes deep facial pain during swallowing due to pressure of the pharyngeal wall against an elongated styloid process or ossified stylohyoid ligament. This mechanical irritation occurs specifically during swallowing movements. Trotters syndrome involves nasopharyngeal tumors, glossopharyngeal neuralgia is purely neurologic, and histamine cephalgia is vascular headache.

General MedicineAtherosclerosis is inversely proportional to HDL level. HDL (High-Density Lipoprotein) is protective against atherosclerosis as it transports cholesterol from peripheral tissues to the liver for disposal. Higher HDL levels reduce atherosclerotic risk, while LDL, VLDL, and chylomicrons promote atherosclerosis.
