Public Health DentistryIn a double-blind study, neither the participants nor the experimenters know who is receiving the treatment or the placebo. This is to prevent any bias in the study results due to the expectations of the participants or the researchers. The statement that the investigator can omit data that fails to support the hypothesis is not correct; data should be analyzed as is to maintain the integrity of the study.

Oral Surgery
Dilacerated roots (roots with a sharp bend or curve) make extraction difficult because the curved shape can lock the tooth into the socket, requiring careful surgical removal.
Nonvital teeth (dead teeth) are often more brittle and prone to fracture during extraction attempts.
Hypercementosis of roots (excessive buildup of cementum on the roots) increases the root's bulk, making it harder to fit through the alveolar bone and socket during extraction.
Sharp cusps are part of the tooth's crown and do not affect the difficulty of extraction, which primarily depends on the root morphology and surrounding bone structure.
