Essential Minerals for Bone Health

Essential Minerals for Bone Health

The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Tooth Anatomy

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.

Minerals

Minerals

Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.

Summary

A natural mineral dietary supplement (NMDS) and a placebo equally reduced dentinal hypersensitivity. Neither NMDS nor placebo significantly improved gingival inflammation in this study.

Area of Science:

Oral Health
Dental Research
Mineral Supplementation

Background:

Dentinal hypersensitivity and gingival inflammation are common oral health issues.
Natural mineral dietary supplements (NMDS) from geothermal sources are explored for therapeutic benefits.
Fluoride and other minerals in NMDS may influence oral health outcomes.

Purpose of the Study:

To evaluate the efficacy of an NMDS on gingival health and dentinal hypersensitivity.
To compare the effects of NMDS with a placebo (de-ionized water).
To assess changes in gingival inflammation and dentinal sensitivity over an 8-week period.

Main Methods:

A double-blind, randomized, quasi-experimental pre/post-test design.
Participants (n=70) with gingival inflammation and sensitivity were allocated to NMDS or placebo groups.
Gingival Index and visual analogue scale for dentinal sensitivity (tactile and evaporative stimuli) were used for measurements.

Main Results:

Both NMDS and placebo groups showed a significant reduction in dentinal hypersensitivity over 8 weeks.
No statistically significant difference in dentinal hypersensitivity reduction was observed between the NMDS and placebo groups.
Gingival inflammation levels did not show statistically significant changes within or between the groups.

Conclusions:

The NMDS and de-ionized water were equally effective in reducing dentinal hypersensitivity.
Neither the NMDS nor the placebo demonstrated significant efficacy in reducing gingival inflammation.
Further research is needed to explore the specific effects of NMDS components on oral health.
