Tooth Anatomy01:21

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Teeth01:15

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Local Anesthetics: Differential Sensitivity of Nerve Fibers01:24

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Area of Science:

  • Dentistry
  • Oral Health

Background:

  • Dentine sensitivity (DS) is a prevalent condition with various etiological factors and mechanisms.
  • Understanding the diagnosis and treatment of DS is crucial for effective patient management.

Purpose of the Study:

  • To review the definition, prevalence, etiology, mechanisms, diagnosis, and treatment of dentine sensitivity.
  • To examine the efficacy and modes of action of various DS treatments, including potassium salts, strontium salts, bioglasses, arginine/calcium carbonate, adhesives, and oxalates.
  • To discuss methods for evaluating treatment modalities, focusing on laboratory and randomized controlled clinical trials.

Main Methods:

  • A comprehensive literature search was conducted using PubMed, Ovid Medline, and Cochrane reviews.
  • Focused on randomized, controlled, and blinded clinical studies for evaluating the efficacy of DS treatments.
  • Included analysis of laboratory and clinical studies, offering insights into the limitations of existing systematic reviews, such as those on oxalate use.

Main Results:

  • Various treatment modalities for dentine sensitivity were examined, including their mechanisms of action.
  • The review discusses the methodologies employed in evaluating these treatments.
  • New insights into the shortcomings of previous systematic reviews on specific treatments like oxalates were provided.

Conclusions:

  • A novel desensitizing mouthrinse containing 1.4% potassium oxalate (Listerine® Advanced Defence Sensitive) is introduced.
  • Readers are encouraged to assess the significance of managing dentine sensitivity.
  • The advantages of regular use of this potassium oxalate mouthrinse, particularly its resistance to erosive and abrasive challenges, are highlighted.
