DENTINAL HYPERSENSITIVITY

Dentinal Hypersensitivity, as described in this section is not really periodontal disease or condition of parodont. However, dentinal Hypersensitivity appears so often in the course of successful conservative periodontal treatment that clinicians should be aware of this condition, you need to understand its origin, and must be able to provide a range of treatments for the condition.

1. Overview of hypersensitivity of teeth

A. Description

1. Dentinal hypersensitivity is a short, sharp painful reaction that occurs when in some areas exposed dentin exposed to mechanical (touch toothbrush bristles), thermal (ice cream), chemical (acidic grapefruit) stimuli. For example, the person may experience pain when cleaning a particular tooth, or when there is sweet, sour, or acidic foods. Some patients with this disease breathing in the cold air, while you go outside in cold weather can have a similar painful reaction.

2. Dentinal Hypersensitivity associated with exposed dentin.

a. Exposed dentin dentin that is visible to the mouth due to the recession of the gums that, as a rule, covers dentin or absence of enamel due to damage to the tooth crown.

B. Dentin can be exhibited in a small area or exposed, in a vast area of the tooth.

c. Since the recession of the gingival margin is a very common condition, fortunately, not all affected hypersensitivity dentin.

B. precipitating factors sensitivity

1. As already mentioned, the dentinal Hypersensitivity usually associated with gingival recession, although exposure dentin may also result due to the destruction of the enamel.

2. Resolution of the inflammatory process in periodontal after successful conservative periodontal treatment of patients with periodontal disease often results in impacts on small parts of the roots of the teeth that can demonstrate dentinal Hypersensitivity.

3. It is common for dentinal Hypersensitivity to receive the following surgical treatment of periodontitis, but the sensitivity can be associated with non-surgical periodontal therapy is discussed in this Chapter.

4. In the patient's eyes increased tooth sensitivity may be a direct result of non-surgical treatment, but most of all the sensitivity of the results from the fields of clinical attachment loss that occurred before the start of treatment procedures. C. fundamental basis Hypersensitivity

1. Evidence suggests that the origin of the dentinal Hypersensitivity due to hydrodynamic theory of dentine sensitivity. Important elements of this theory are outlined below.

a. Dentinal tubules to penetrate into the dentin-how long, tiny tunnels within the thickness of the dentin. Fig. 24-4 shows the details of these dentinal tubules.

B. As dentinal surface became visible, open dentinal tubules, as a rule, slowly close through the process of calcification, which effectively blocks the opening of each channel.

c. Sometimes the natural process of closing dentinal tubules does not occur, leaving the tube to open or patent. These open or patent tubules contain liquids.
