Brown tumors are benign fibro-osseous lesions that occur in the context of hyperparathyroidism due to increased osteoclast activity and bone resorption. They are typically seen in areas of high bone turnover.

EndodonticsIn primary teeth, intrusion is common because alveolar bone is pliable. Primary teeth characteristics that predispose to intrusion: 1) The alveolar bone around primary teeth is more cancellous and flexible, 2) This pliable bone allows the tooth to be pushed deeper into the socket rather than being displaced laterally or avulsed, 3) The root structure of primary teeth also contributes to this pattern. While vertical overlap and lip protection may influence injury patterns, the primary factor is the pliable nature of the developing alveolar bone in children.

The significant differences between self-etch
primers and total-etch primers are: Wetness of dentine: In total-etch, dentine must be kept moist
after etching to prevent collagen collapse. In self-etch, no rinsing step is required, so
dentine wetness is not critical. Time of application: Total-etch involves separate etching, rinsing,
and priming steps → longer procedure. Self-etch combines etching and priming in one
step → faster. Removal of smear layer: Total-etch completely removes the smear layer
with phosphoric acid. Self-etch modifies and incorporates the smear
layer into the hybrid layer. Bond strength: Both systems can achieve comparable bond strength
to enamel and dentine when properly applied. Hence, bond strength is NOT a significant difference
between the two systems.Explanation

RadiologyExplanation: Among the imaging techniques listed, a CT (computed tomography) scan typically involves the highest radiation exposure to the patient. This is due to the multiple X-ray images taken from different angles to create cross-sectional images of the body.

Gingival retraction is a technique used in dentistry to temporarily move the gum tissue away from the tooth to create a clear impression of the tooth and the surrounding area. Retraction cord, also known as gingival retraction cord, is a common and widely used mechanical method for gingival retraction during final impression procedures. The cord is typically soaked in a chemical agent to control bleeding and tissue fluid, then gently placed into the sulcus (the space between the tooth and the gum).

Community Dentistry"Sullage" refers specifically to the waste water generated from sinks, baths, and kitchens that does not contain human waste. "Sewage" includes waste that may contain pathogens and is typically discharged from toilets. Thus, kitchen waste water is more accurately described as sullage.
