Corticosteroids are generally considered pregnancy category C drugs, meaning animal studies have shown an adverse effect on the fetus, but there are no adequate and well-controlled studies in humans. Amoxicillin and erythromycin are typically category B, and lignocaine (lidocaine) is also category B.

EndodonticsReversible pulpitis is a mild inflammation of the dental pulp that is typically relieved by the application of cold water or air. The transient pain is caused by the movement of fluid within the dentinal tubules when exposed to stimuli, which is consistent with the hydrodynamic theory of pain.

Physiology
Gastrin is a hormone released by G cells in the gastric antrum in response to the presence of food, especially protein. It acts on parietal cells in the gastric glands, stimulating them to produce and secrete hydrochloric acid (HCl) and intrinsic factor, which is essential for vitamin B12 absorption. Gastrin is a critical component of the gastric phase, which is responsible for the bulk of gastric acid secretion.

FPDs are generally contraindicated for several reasons: Growth and Development: Children are still in their
growth phase, and their jaws and teeth are developing. Placing a fixed
prosthesis can interfere with normal growth patterns and may require
adjustments or replacements as the child grows. Eruption of Permanent Teeth: In younger patients,
especially those under 10, many of the permanent teeth have not yet erupted.
Using FPDs in this age group can complicate future dental treatments, as the
position of the teeth may change with the eruption of permanent teeth.

Oral PathologyDown syndrome is characterized by maxillary hypoplasia, which gives the appearance of relative mandibular prognathism. The underdeveloped maxilla, combined with a relatively normal-sized mandible, creates the characteristic facial profile. Other features include macroglossia, high arched palate, delayed tooth eruption, and increased periodontal disease susceptibility. The maxillary hypoplasia is a key diagnostic facial feature along with the typical mongoloid facies.
