Light-cured resins generally have less shrinkage and are more aesthetically pleasing due to their ability to be polymerized to a higher degree. They also offer improved bond strength compared to chemically cured resins.

The Nikolsky sign is positive in conditions with intraepidermal acantholysis (e.g., Pemphigus Vulgaris, SSS, TEN). Bullous pemphigoid involves subepidermal blistering where the entire epidermis lifts off the dermis, hence Nikolsky sign is typically negative.

Osteogenesis imperfecta is a genetic collagen disorder that results in extreme bone fragility. Multiple fractures seen in utero on ultrasound are a hallmark of severe forms (Type II) of this condition.

Prosthodonticsguiding planes are flat, polished surfaces on the abutment teeth that guide the RPD along a specific path during insertion and removal. They are located adjacent to the edentulous area and are crucial for the proper seating and function of the denture.

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.

Oral PathologyProthrombin time (PT) is a measure of the blood's clotting ability. In dentistry, a PT level of 20% below normal is often considered a threshold for increased risk of bleeding during surgical procedures such as tooth extraction. At this level, the patient may be at risk for prolonged bleeding or hemorrhage. Dentists typically assess a patient's coagulation status before performing invasive procedures, especially if the patient has a known bleeding disorder or is on medications that affect clotting.
