Summary
Dental bitewing X-rays should have intervals tailored to individual caries risk. Children with prior caries need annual checks, while those without may benefit from 8-year intervals.
Area of Science:
- Dentistry
- Radiology
- Public Health
Background:
- Bitewing examinations are crucial for detecting approximal caries.
- Balancing early lesion detection with radiation exposure is key.
- Determining appropriate intervals requires understanding caries risk.
Purpose of the Study:
- To estimate caries risk in the Swiss school population.
- To inform appropriate intervals for bitewing examinations based on caries risk.
Main Methods:
- Analysis of longitudinal data from 591 schoolchildren in Zurich.
- Examinations conducted at 4-year intervals.
- Carried out caries risk assessment based on age and prior caries experience.
Main Results:
- Overall caries risk was 7.1% for 7-year-olds and 17.6% for 11-year-olds over 4 years.
- 7-year-olds without prior caries had a 2.2% risk; those with prior caries had a 24.2% risk.
- 11-year-olds without prior caries had a 7.5% risk; those with prior caries had a 38.5% risk.
Conclusions:
- Caries risk varies significantly based on previous caries experience.
- Proposed 8-year interval for 7-year-olds with no caries experience.
- Proposed 1-year interval for 7-year-olds with existing caries experience.

01:21Tooth 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.

01:20Imaging Studies for Cardiovascular System III: X-Ray
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

01:25Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
01:24X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
01:15Teeth
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...

01:30Radiological Investigation I: X-ray and CT
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...
