Scientific Explanation of Key Terms

This section delves deeper into the scientific basis behind some of the crucial dental terms encountered in the practice test. Understanding the underlying principles enhances comprehension and retention.

• Enamel: This is the outermost layer of the tooth, composed primarily of hydroxyapatite, a crystalline mineral. Its highly mineralized structure provides exceptional hardness and resistance to wear and tear, crucial for protecting the underlying dentin and pulp. The structure of enamel is unique, with rod-like structures that offer strength and resilience. Its inherent resistance to acids, while not absolute, is vital for preventing dental caries (cavities).

• Dentin: Located beneath the enamel, dentin is a living tissue that constitutes the bulk of the tooth structure. It is composed of dentin tubules, microscopic canals containing odontoblastic processes. These processes are responsible for the tooth's sensitivity to stimuli like temperature changes or pressure. Dentin is less mineralized than enamel, making it more susceptible to decay.

• Pulp: This is the innermost part of the tooth, containing blood vessels, nerves, and connective tissue. Its main function is to provide nourishment to the tooth and transmit sensory information. Inflammation of the pulp (pulpalgia or pulpitis) is a significant dental concern, often requiring root canal treatment to alleviate pain and prevent infection.

• Gingivitis: This is an inflammation of the gums, often caused by bacterial plaque buildup. Gingivitis is the initial stage of periodontal disease and is typically reversible with good oral hygiene practices. However, if left untreated, it can progress to periodontitis, leading to bone loss and tooth loss.

• Periodontitis: This is a more advanced form of gum disease, characterized by inflammation and infection of the supporting tissues of the teeth, including the gums, periodontal ligament, and alveolar bone. Periodontitis can lead to loosening and eventual loss of teeth. Treatment involves scaling, root planing, and sometimes surgical intervention.

Frequently Asked Questions (FAQ)

• Q: What is the difference between a crown and a bridge?

  • A: A crown is a cap that covers a damaged or weakened tooth. A bridge is a prosthetic device used to replace one or more missing teeth.

• Q: What is the difference between gingivitis and periodontitis?

  • A: Gingivitis is an inflammation of the gums, while periodontitis is a more severe infection that affects the supporting tissues of the teeth.

• Q: What is the role of fluoride in dental health?

  • A: Fluoride strengthens tooth enamel, making it more resistant to acid attacks from bacteria, thereby reducing the risk of cavities.

• Q: What is a root canal?

  • A: A root canal is a procedure performed to remove the infected pulp from a tooth and prevent further infection.

• Q: What are dental sealants?

  • A: Dental sealants are plastic coatings applied to the chewing surfaces of teeth to prevent cavities.

• Q: What is an impacted tooth?

  • A: An impacted tooth is one that is unable to erupt normally through the gums. This often requires surgical removal.
