1. Description
A. a comprehensive system of answers
1. The immune system is a set of responses that protects the body from infections, bacteria, viruses, fungi, toxins and parasites (Fig. 8-1).
2. Bacteria, viruses, and other pathogens attack the human body more than 100 million times a day. For this reason, the human body, the immune system tries to control the rapid spread of invasion by microorganisms.
1. A number of other terms used to describe excessive occlusive forces. Two of these conditions functional and parafunctional occlusive forces.
a. Functional occlusion forces and normal forces produced during the act of chewing of food.
B. Parafunctional occlusive forces in the teeth contact when it is not the act of eating.
A. injury from occlusion
1. Direct damage periodontal can result from excessive occlusive (or biting) forces on the teeth.
2. When excessive occlusive forces to damage the tissues of parodentium, this is called trauma from the bite.
A. Incorrect Crown Placement. The crown is a metal, ceramic or ceramic-store-metal floor severely damaged teeth. Placing a crown on a damaged tooth is a common mechanism used to store badly damaged tooth.
1. Crowns can sometimes be placed incorrectly, when the tooth structure is minimal. There may be direct damage periodontal, when the edge of the crown (called fields) are placed below the gingival margin and too close alveolar bone.
2. The crown margin, closer than 2 mm up to the crest of the alveolar bone in the resorption of the alveolar bone (Fig. 7-11).
In the fourth section discusses a number of local factors that can cause direct damage to tissues. These factors can also change the course of periodontitis in some areas. Some local factors that could directly damage the tissues of parodentium include food, stiffness, habits of the patient and the restoration or faulty devices.
1. Direct damage from the food situation.
A. Definition. Food impaction refers to shove food (such as pieces of hard meat) between the teeth while chewing, catching food in the interdental areas.
Pathogenicity can be described as the ability of pathogenic agent to actually produce the disease. In the dental context of pathogenicity can be considered as the ability of plaque biofilm the cause of periodontal disease. Plaque biofilm pathogenicity relates to the character plaque biofilm, and not simply increase the amount of plaque biofilm.
1. Undisturbed Plaque Biofilm Growth
The Plaque A. Biofilms Maturation
1. Plaque biofilm allowed to grow undisturbed said "Mature". As plaque biofilm grows up, becomes colonization larger number of bacteria.
1. Naturally occurring development grooves and valleys on the surface of the teeth often cause difficulties self-care on site and can be a local factor for
gingivitis and periodontal disease because of the increased plaque biofilm hold it in place.
2. In the natural development of individual incisors, GROOVE forms on the lingual surfaces of the tooth. This groove development of the defect is called palatogmgival groove and most commonly seen on the maxillary lateral incisors. Plaque biofilm storage is a common problem associated with palatogingi Val-NOTCH with the NOTCH is often difficult or impossible to effectively clean (Fig. 7-4).
Morphology module is the study of the anatomical features of the tooth surface. There are many local factors that relate to the morphology of the teeth. Some of these differences in morphology of the teeth can occur when a tooth requires restoration, and some of them are simply due to differences in the way your teeth fit.
And poorly contour restoration
Tartar gives the surface of the teeth using several different modes, and attachments different mechanisms may even exist in the same calculus Deposit.
1. Investment film
a. Calculus can attach to the surface of the tooth by joining a film on the surface. The film is a thin, bacteria-free membrane that forms on the teeth during the late stage of the eruption.
B. This mode of attachment often occurs on the surface of the enamel.
1. Crystalline forms of Tartar. As the calculation of age on the surface of the tooth, inorganic component changes through several different crystalline forms. It is interesting to note that some of these crystalline forms of the terms very similar to crystal form in the tooth itself.
a. Newly formed calculus deposits appear as crystalline form called brushite.
