Teeth

1.6K
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...

Diabetes Mellitus: Type 2 and Gestational

4.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

787
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Tooth Anatomy

2.0K
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...

Diabetes: Symptoms, Diagnosis, and Complications

2.0K
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Summary

Regular dental visits and tooth extractions may be linked to better blood glucose control in adults. Frequent dental care, especially for those with obesity, shows a promising association with improved glycemic management over three years.

Area of Science:

  • Oral Health
  • Endocrinology
  • Public Health

Background:

  • Glycemic control is crucial for managing diabetes.
  • Dental health is increasingly recognized as a factor influencing systemic health.
  • Previous research suggests links between oral health and metabolic conditions.

Purpose of the Study:

  • To investigate the association between tooth extraction, dental visit frequency, and blood glucose levels.
  • To analyze these associations over a 3-year period in middle-aged and older adults.
  • To identify potential links between dental care patterns and glycemic status.

Main Methods:

  • Analysis of a large health insurance claims database (DeSC, Tokyo, Japan).
  • Inclusion of 31,373 individuals aged 45-70 years.
  • Categorization based on annual dental visits and tooth extractions; primary outcome: high blood glucose (HbA1c≥6.5% or fasting plasma glucose ≥126 mg/dl).

Main Results:

  • Tooth extraction at baseline was associated with lower odds of high blood glucose levels after 3 years.
  • Three or more yearly dental visits correlated with lower odds of high blood glucose, especially in individuals with high baseline glucose and BMI ≥25.0 kg/m².
  • Findings suggest a link between regular dental care and improved glycemic control, particularly in obese individuals.

Conclusions:

  • Regular dental care and tooth extraction may be associated with better glycemic control.
  • Further research is needed to explore causal relationships and the impact of specific dental interventions like periodontal treatment on diabetes management.
