Sealants are superior to control without sealants or fluoride varnishes in terms of effectiveness and safety in halting or preventing the progression of non-cavitated carious lesions. To learn more about the relative qualities of the various kinds of sealant materials, more research is required.
Sealants had a lower risk of developing carious lesions in the occlusal surfaces of permanent molars than those who did not (odds ratio [OR], 0.15; 95 percent confidence interval [CI], 0.08-0.27). The authors discovered that sealants decreased the incidence of carious lesions after 7 or more years of follow-up when they reviewed studies whose researchers had compared sealants with fluoride varnishes (OR, 0.19; 95 percent CI, 0.07-0.51); however, this finding was supported by low-quality evidence. The authors were unable to establish a hierarchy of efficacy among the studies whose researchers had made side-by-side comparisons based on the available evidence.

Answer:
Yeah true
Explanation:
In non steroid hormones the secondary messenger is Ca2+, IP3( Inositol triphosphate ), or cyclic AMP.
Answer:
Ulna
Explanation:
The are two primary bones in the forearm: the radius and the ulna. The radius is on the lateral side of the forearm and the ulna on the<em> medial side.</em>
The ulna is a long bone that stretches from the elbow to the smallest finger, it narrows when it approaches the wrist.
The ulna forms part of the wrist joint and the elbow joint.
If the ulna is fractured, a cast that runs along the forearm is applied till the bone regrows together again.
Answer:
With respect to the anterior pituitary gland, it is true that it is often referred as the "master gland" of the endocrine system (option C).
Explanation:
The pituitary gland —also called hypophysis— divided into two parts, an anterior part called the adenohypophysis and a posterior part called the neurohypophysis.
The adenohypophysis or anterior pituitary gland is in charge of the secretion of hormones that serve to regulate the hormonal secretion of other glands, such as the thyroid, the suprarenal glands and the gonads. This is the reason why it is considered and often referred as the "master gland" of the endocrine system.
The neurohypophysis depends on the control of the hypothalamus and the neurotransmitters that this structure sends to the pituitary, releasing hormones whose effect is direct on the target organ.
The other options are not correct because:
<em> A. Anterior pituitary does not </em><u><em>release hormones made by the neurons in the hypothalamus</em></u><em>.
</em>
<em> B. Adenohypophysis has </em><u><em>hormone-producing cells</em></u><em>.
</em>
<em> D. The anterior pituitary is </em><u><em>not regulated by the hypothalamus and is considered part of the endocrine system</em></u><em>.</em>
Answer:
Ringworm, touching a contaminated surface (blankets or doorknob) or coming into to contact with someone who's infected (hugging or handshakes) can lead to further spread of the infection.
Speaking from personal experience, it sucks and it's very itchy.
