Cystic fibrosis follows an autosomal recessive inheritance pattern. Osteogenesis imperfecta and Achondroplasia are typically autosomal dominant, while Treacher Collins is most commonly dominant but can rarely be recessive.

The parakeratinised type of odontogenic keratocyst (OKC) is significantly more common than the orthokeratinised type, making up the vast majority of cases.

Biochemistry
Saturated fatty acids are a type of fat that has a chemical structure with a
single bond between each carbon atom in the fatty acid chain and no double
bonds. These types of fats are typically solid at room temperature. Out of the
given options, stearic acid (C18:0) is the only saturated fatty acid. The others
are:
1. Oleic acid (C18:1) is a monounsaturated fatty acid, which means it has one
double bond. It is commonly found in olive oil, canola oil, and avocados.
2. Linolenic acid (C18:3) is a polyunsaturated fatty acid, specifically an
omega-3 fatty acid, with three double bonds. It is found in plant sources like
flaxseeds, chia seeds, and walnuts.
3. Arachidonic acid (C20:4) is also a polyunsaturated fatty acid, an omega-6
fatty acid with four double bonds. It is found in animal fats, such as meat, and
in smaller amounts in some plant oils like sunflower oil and peanut oil.
Stearic acid, on the other hand, is a common saturated fatty acid found in
various animal fats and certain vegetable oils like coconut oil, palm kernel
oil, and cocoa butter. It is known for its role in the structure of cell
membranes and as a precursor for the biosynthesis of cholesterol in the body.
While it is important to consume fatty acids for good health, excessive
consumption of saturated fatty acids has been associated with higher levels of
LDL (low-density lipoprotein) cholesterol, which is often referred to as "bad"
cholesterol, and an increased risk of heart disease. However, it is important to
maintain a balanced diet that includes both saturated and unsaturated fatty
acids in moderation.

PeriodonticsJuvenile periodontitis, now referred to as localized aggressive periodontitis, is characterized by the loss of periodontal attachment and bone in adolescents and young adults, often without the presence of significant calculus. This distinguishes it from other forms of periodontitis, where calculus is typically present.

NEETMDSAnterior crossbite in a 10-year-old child, particularly if functional, can sometimes be a self-correcting anomaly, especially if the underlying cause (e.g., premature contact) is addressed or with natural growth changes. Other conditions like buccoversion of the mandibular first molar, anterior open bite, and flaring of incisors typically require intervention to correct.

Oral SurgeryA hypoglycemic episode occurs when a person's blood sugar levels drop too low. For a diabetic patient on insulin, insulin helps move glucose from the blood into the cells, lowering blood sugar levels. If a patient takes their usual dose of insulin but then omits a meal, such as breakfast, there is not enough glucose entering the bloodstream from food to balance the effect of the insulin. This leads to an excessive drop in blood sugar, resulting in hypoglycemia.

Huntington's disease is a relatively rare genetic disorder with a prevalence of approximately 1 in 10,000 individuals. It is an autosomal dominant condition, meaning that a person only needs to inherit one copy of the mutated gene from a parent to develop the disease. The onset is typically in the fourth or fifth decade of life, and it is characterized by chorea, behavioral disturbances, and progressive cognitive decline.
