Facts About Salivary

Salivary glands may seem like small, insignificant organs in our bodies, but they actually play a crucial role in maintaining our overall health. These remarkable glands produce saliva and empty it into our mouths through tiny ducts, constantly working behind the scenes to keep our mouths moist and functioning properly.

Saliva: A Multitasking Marvel

Saliva is not just a simple fluid in our mouths. It serves multiple purposes that are essential for our well-being. First and foremost, saliva lubricates our mouth and throat, making it easier for us to speak, swallow, and eat. We often take this function for granted, but without saliva, even the simplest tasks would become uncomfortable and challenging.

Moreover, saliva aids in the digestion process by breaking down food particles and making them easier to digest. The primary enzyme in saliva, called salivary amylase, plays a crucial role in carbohydrate digestion. This enzyme helps break down complex carbohydrates into smaller molecules, such as sugars, facilitating their absorption in the body. So, the next time you enjoy a meal, remember that your salivary glands are contributing to the digestion process right from the start!

Shielding Our Teeth from Harm

In addition to its role in lubrication and digestion, saliva also acts as a natural defense mechanism for our teeth. It contains minerals, such as calcium and phosphate, which help to remineralize the tooth enamel and keep it strong. The remineralization process helps counteract the harmful effects of cavity-causing bacteria, protecting our teeth from decay and cavities. Saliva also helps neutralize acids in the mouth, reducing the risk of enamel erosion and tooth sensitivity.

Saliva: A Window into Health

Did you know that our saliva can actually provide valuable insights into our overall health? Research has shown that certain changes in saliva composition can be indicative of various health conditions, ranging from diabetes to autoimmune disorders. Scientists are exploring the potential use of saliva as a diagnostic tool, making it easier to detect certain diseases and monitor their progression.

In summary, salivary glands are more than just active producers of saliva. They are fascinating organs that are instrumental in maintaining oral health and aiding in the digestion process. Saliva truly is a multitasking marvel, acting as a lubricant, digestive aid, and protective shield for our teeth. Next time you enjoy a meal or have a comfortable conversation, take a moment to appreciate the remarkable role played by your salivary glands.

“Our salivary glands may be small, but they have a big impact on our overall well-being. From lubricating our mouths to aiding in digestion and protecting our teeth, these glands truly deserve our appreciation.”

Eight Surprising Facts About DNA from Saliva

[youtube v=”eE5K2gA7wjs”]

The Importance of DNA in Saliva

  • Fact #1: 74% of the DNA in saliva comes from white blood cells, with the remaining derived from buccal epithelial cells.
  • Fact #2: The majority of DNA in saliva is of human origin, with only a small percentage (11%) being bacterial DNA.

The Purity and Integrity of Saliva DNA

  • Fact #3: Despite low A260 A230 ratios, DNA from saliva is of high purity. Carbohydrates present in saliva do not affect downstream applications.
  • Fact #4: When extracting DNA from saliva samples, RNA may co-purify with DNA. However, this will not impact downstream applications and can be removed if necessary.

Saliva as an Alternative to Blood for DNA Analysis

  • Fact #5: Studies have shown that DNA extracted from saliva samples is of comparable quality and integrity to blood, making it a reliable and cost-effective alternative for DNA analysis.
  • Fact #6: Saliva has been successfully used for whole genome sequencing, providing consistent results across different technology platforms.

Cost and Convenience of Saliva DNA Collection

  • Fact #7: Collecting DNA from saliva is less expensive than collecting it from blood, as it eliminates the need for phlebotomists, medical supplies, and shipping, resulting in cost savings of up to 80%.
  • Fact #8: Different methods for collecting oral DNA samples exist, but origin saliva collection offers higher yields and quality, making it a preferred choice for researchers and clinicians worldwide.

By utilizing saliva samples, researchers and clinicians can benefit from the high quality and performance of DNA, combined with the ease of collection and efficient transport. Saliva provides a wealth of genetic information, all while offering a non-invasive and cost-effective alternative to blood. Request evaluation kits at to start incorporating saliva DNA into your next study.

“Saliva DNA analysis offers a multitude of advantages, including its cost-effectiveness, non-invasiveness, and comparable quality to blood analysis. It’s a game-changer for genetic research and clinical applications.”

facts about salivary


Question 1: How do salivary glands function?

Answer 1: Salivary glands produce saliva and release it into the mouth through ducts. Saliva is essential for lubricating the mouth and throat, aiding in swallowing and digestion, and protecting the teeth from cavity-causing bacteria.

Question 2: What is the role of saliva in digestion?

Answer 2: Saliva contains an enzyme called salivary amylase, which breaks down carbohydrates into smaller molecules, including sugars. This process initiates the digestion of carbohydrates even before they reach the stomach.

Question 3: Can salivary glands be affected by disorders?

Answer 3: Yes, salivary glands can be affected by various disorders. Some common salivary gland disorders include salivary gland stones, infections, tumors, and autoimmune diseases. These conditions can impact salivary gland function and overall oral health.

Question 4: How does saliva contribute to oral health?

Answer 4: Saliva plays a significant role in maintaining oral health. It helps wash away food particles, neutralizes acids in the mouth, and provides minerals that aid in tooth remineralization. Insufficient saliva production can lead to dry mouth, increasing the risk of tooth decay and gum disease.

Question 5: Are there any interesting facts about salivary glands?

Answer 5: Salivary glands are not only crucial for oral health but also demonstrate fascinating characteristics. For example, there are three main pairs of salivary glands: parotid glands, submandibular glands, and sublingual glands. Additionally, the composition of saliva can vary throughout the day and is influenced by factors such as stress and certain medications.
