Community DentistryFluoride is absorbed primarily in the gastrointestinal tract, with the stomach and small intestine being the main sites of absorption. The acidic environment of the stomach facilitates the dissolution of fluoride, allowing it to be absorbed effectively. While some absorption occurs in the large intestine, the majority takes place in the stomach and small intestine

Oral Pathology1. Anodontia: This is the complete absence of teeth. It is a rare condition
where an individual fails to develop any teeth.
2. Oligodontia: This term is used when an individual has fewer teeth than the
typical dental formula, which is six incisors, two canines, two premolars, and
six molars in the permanent dentition (excluding the third molars or wisdom
teeth). The term "hypodontia" is often used synonymously with oligodontia, but
hypodontia can also refer to a broader range of conditions characterized by the
congenital absence of one or more teeth, whereas oligodontia is more
specifically the absence of six or more teeth.
3. Microdontia: This condition involves teeth that are smaller than normal. It
can affect either the primary or permanent dentition and may involve one tooth
or multiple teeth.
4. Dens in dente: This is a rare developmental anomaly where a tooth forms
within the dental crown of another tooth, typically in the form of a small
tooth-like structure. It is not a condition of tooth number but rather an
abnormality of tooth structure.

PhysiologyAnswer: 4) Increase in heart rate and increase in stroke volumeExplanation: Thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3), enhance the effects of catecholamines on the cardiovascular system, leading to increased heart rate and stroke volume. This results in a higher cardiac output, which is essential for meeting the increased metabolic demands during stress or exercise.

Dental MaterialsThe significance of the direction of the applied force during condensation is that it affects the marginal integrity and adaptation of the material to the cavity walls. It is important to direct the force at an appropriate angle to ensure proper condensation and seating of the material.
