In the second-trimester dental care guidelines, organogenesis is complete.

• A. It is ongoing
• B. It is complete
• C. It is not yet complete
• D. It is irrelevant

Answer: (B)

Organogenesis is the formation of organs, which occurs mainly during the early weeks of pregnancy in the first trimester. By the start of the second trimester, most organs are formed, and the fetus shifts toward growth and maturation of those structures rather than creating new organs. That timing is why the second-trimester dental care guidelines describe organogenesis as complete. Knowing this helps clinicians plan care with a focus on maternal comfort and fetal safety using standard precautions (like shielding during radiographs and avoiding unnecessary procedures), rather than concerns about ongoing organ formation. Some tissues continue to mature after organogenesis, but the major developmental window for forming organs has passed, making the statement true.
