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.

EndodonticsThis question appears to be misplaced in an endodontics exam as it relates to orbital fractures. Enophthalmos (sunken eye) can occur in blow-out fractures due to increased orbital volume.

When mercury comes in contact with the
alloy powder (mainly silver, tin, copper):
Mercury first dissolves the outer surface of the alloy particles.
After dissolution, new reaction products begin to form:
Ag–Hg (gamma-1 phase) from reaction with silver
Sn–Hg (gamma-2 phase) from reaction with tin (in low-copper amalgam)
Cu–Sn (eta phase) replaces gamma-2 in high-copper amalgam

Physiology
Answer: 2) It prevents the muscle from fully relaxing between contractions
Explanation: The latch effect in smooth muscles refers to the ability of phosphorylated myosin heads to maintain their attachment to actin filaments even after calcium levels decrease, thus preventing full relaxation without further calcium influx. This sustained contraction with minimal energy expenditure is a characteristic feature of smooth muscles.

In children, mandibular fractures typically heal rapidly, and clinical examination (such as checking for pain, mobility, and malocclusion) is often sufficient to assess bony union after an appropriate healing period. Imaging techniques like OPG or CT scans are generally reserved for initial diagnosis, complex cases, or suspected complications rather than routine follow-up for simple, well-managed fractures.

For caries prevention, a 0.2% sodium fluoride mouth rinse is
typically recommended for use once weekly. This regimen provides sufficient
fluoride exposure to strengthen tooth enamel without causing adverse effects.
