General Medicine
For a diagnosis of systemic lupus erythematosus (SLE), at least four out of the eleven listed disorders must be present. These include malar rash, discoid rash, photosensitivity, oral ulcers, arthritis, serositis, renal disorder, neurologic disorder, hematologic disorder, immunologic disorder, and positive antinuclear antibodies.

While great for temporary cementation, its primary disadvantage for permanent use is its potential to cause tooth discoloration and pulpal irritation.

EndodonticsWhen performing vital tooth bleaching, local anesthesia is NOT routinely used because: 1) The procedure is generally painless, 2) Most patients experience only mild sensitivity which is manageable, 3) Anesthesia can interfere with patient feedback regarding sensitivity. Essential procedures include: prophylaxis to remove debris, protective eyewear for both patient and operator due to strong oxidizing agents, and polishing after treatment to smooth any etched enamel surfaces.

The condition described, which includes brown skin pigmentation (hyperpigmentation), hypoplasia of the kidney and spleen, absent or hypoplastic thumb or radius (limb malformations), microcephaly, and mental and sexual retardation, is characteristic of Fanconi anemia (FA).

EndodonticsPulpectomy is the complete removal of the pulp tissue from the pulp chamber and root canals of a tooth. This procedure is the standard treatment for irreversible pulpitis, as the inflamed and infected pulp cannot heal and must be entirely removed to save the tooth and prevent further infection.

Pharmacology
Alkalinization of urine is used in patients receiving high dose methotrexate to promote renal excretion and to avoid nephrotoxicity IV Sodium bicarbonate is used to maintain urine pH above 7.0 to avoid precipitation of methotrexate (a weak acid) in the acid pH of renal tubules

Public Health DentistryAn expression of probability based on the ratio of the difference between two means, divided by the standard error of the difference, is known as the t value (or t-statistic). This value is used in hypothesis testing to determine if the means of two groups are significantly different.

Oral PathologyTraumatic injury is the most frequent cause of TMJ ankylosis, particularly intra-articular fractures involving the condyle and glenoid fossa. Trauma can cause intra-articular bleeding, fibrin formation, and subsequent fibrosis or bony fusion. Birth trauma, falls, motor vehicle accidents, and mandibular fractures are common causes. Osteoarthritis typically causes joint degeneration rather than ankylosis. Congenital syphilis and traumatic occlusion are rare causes.

Physiology
The somatic sensory area of the parietal lobe, particularly Brodmann's areas 3, 1, and 2, is involved in the interpretation of tactile, proprioceptive, and other sensory information from the body.

Dental Anatomy
Dentinogenesis is the formation of dentin by odontoblasts of mesenchymal origin
located at the periphery of the dental pulp
Dentinogenesis is initiated by the inductive influence of the enamel organ
involving molecular signaling pathways, such as Wnt, Runx-2, and TGF-?. In the
molar tooth, dentinogenesis starts at the late bell stage, and occurs in the
crown as well as root regions.
Predentin, the first organic matrix secreted by odontoblasts, is composed by
proteoglycans, glycoproteins, and collagens.
