3 rd Lecture: Blood: Composition, Specific Functions of each Compartment. Plasma and Serum Differences and Separation

Definition of Blood: Blood is a fluid connective tissue that consists of plasma, blood cells and platelets. It circulates throughout our body delivering oxygen and nutrients to various cells and tissues. It makes up 8% of our body weight. An average adult possesses around 5-6 liters of blood.

4- Comments in C++

Program comments are explanatory statements that you can include in the C++ code. These comments help anyone reading the source code. All programming languages allow for some form of comments.
C++ supports single-line and multi-line comments. All characters available inside any comment are ignored by C++ compiler.

Lecture 10 (Complex amalgam restorations)

Complex posterior restorations are indicated when tooth structure is missing due to cusp fracture, severe caries lesion development (two or more tooth surfaces are missing), and more retention and resistance forms are needed, or replacement of existing restorative material is necessary. To compensate the lost tooth structure, may be moderate, severe or total, one or more than one retentive device is utilized. The routinely used retentive devices are: i. Slots. ii. Locks. iii. Coves. iv. Cusp Coverage Complex Amalgams. v. Crown lengthening. vi. Pins. vii. Amalgam pin. viii.

Lecture 9 (Dental cements; Base materials)

A base is any substance placed under a restoration (1-2 mm in thickness) that blocks out undercuts in the preparation, acts as a thermal or chemical barrier to the pulp, and/or controls the thickness of the overlying restoration. Bases should have sufficient strength to withstand forces of mastication and condensation of permanent restorations (mechanical protection to the pulp). Zinc-phosphate, polycarboxylate, zinc oxide-eugenol (IRM), glass ionomer and resin cements have all been historically used as bases for direct and indirect restorations.........

Lecture 8 (Dental Cements; liner materials)

Dental cements have been widely used in various clinical applications since the early twentieth century. They are used as filling materials, protective cavity liners, luting materials for crowns, bridges, inlays and orthodontic appliances, root canal fillings, and pulp capping. Various types of cements are available for different purposes. Dental cements are mainly used to provide protection to the pulp against irritants as the following: 1. Thermal protection against temperature changes. 2. Electrical protection against galvanic currents. 3.
