Summary
This study found no significant link between tooth loss and blood pressure in adults. While higher blood pressure was observed in those with no teeth, this association disappeared after accounting for other factors.
Area of Science:
- Public Health
- Cardiology
- Dentistry
Background:
- Cardiovascular diseases (CVD) are a leading cause of premature death.
- Hypertension is a major risk factor for cardiovascular events.
- Previous studies suggest a link between tooth loss and increased blood pressure, but findings are inconclusive.
Purpose of the Study:
- To investigate the association between tooth loss and blood pressure in adult patients.
- To determine if the number of natural teeth correlates with systolic blood pressure (SBP) and diastolic blood pressure (DBP).
Main Methods:
- A cross-sectional study of 270 adults aged 20-59 years.
- Participants were categorized by the number of natural teeth: 10 or more, less than 10, or none.
- Data analyzed using descriptive statistics, independent t-test, ANOVA, and multiple linear regression.
Main Results:
- Mean SBP was 125.3 mmHg and DBP was 78.9 mmHg.
- 29.3% of participants had hypertension; 8.9% were edentulous.
- Initially, increased SBP was observed with greater tooth loss, but this was not significant after adjusting for covariates.
Conclusions:
- Mean SBP was higher in edentulous participants compared to partially edentulous ones.
- No significant association was found between tooth loss and SBP or DBP after adjusting for confounding factors.

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...

372
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

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...

620
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

01:18Hypertension and Regulation of Blood Pressure
3.5K
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

01:28Hypertension I: Introduction
571
Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...
