The lymphoid system, which includes lymph nodes, spleen, and other lymphatic tissues, undergoes significant growth during childhood. By the age of 9-10 years, the lymphoid tissue can reach approximately 200% of its adult size due to the increased demand for immune function during this period. This growth is part of the body's preparation for increased exposure to pathogens as children interact more with their environment.
Orthodontic tooth movement is inhibited by which of the following drugs 1) NSAIDS, such as Brufen 2) OPIOIDS, such as CORTISONE 3) Antibiotics such as tetracycline 4) Vasoconstrictors such as adrenaline
SOLUTION
NSAIDS, i.e. Brufen, etc. inhibit tooth movement as they interfere with production of prostaglandins. • Nimesulide does not interfere with PG production and so can be safely given during tooth movements.
