Design Example: Analyzing Capacity Contours for Flood Risk Assessment01:17

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

325
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Relative Risk01:12

Relative Risk

2.1K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.5K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Buffer Effectiveness02:19

Buffer Effectiveness

55.2K
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...

Framing Effects

7.9K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Biological Effects of Radiation02:59

Biological Effects of Radiation

17.9K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

Summary

Standardized caries risk assessment (CRA) models show a statistically significant association with actual caries status. However, current evidence is insufficient to confirm their effectiveness or validity in predicting future dental caries development.

Area of Science:

  • Dental Public Health
  • Evidence-Based Dentistry
  • Oral Epidemiology

Background:

  • Caries risk assessment (CRA) models are crucial for predicting and preventing dental caries.
  • Standardized CRA models aim to provide consistent and reliable risk evaluations.
  • Previous reviews have not comprehensively evaluated the evidence for standardized CRA models.

Purpose of the Study:

  • To systematically review and synthesize evidence on the validity and effectiveness of standardized caries risk assessment models.
  • To assess the performance of CRA models in identifying individuals at risk for current or future caries.
  • To evaluate the methodological quality of studies investigating CRA models.

Main Methods:

  • A systematic literature search was conducted in PubMed, Scopus, and Embase (2000-2016).

  • Included studies were randomized clinical trials, cross-sectional studies, cohort studies, and validation studies using DMFT/S or ICDAS indices.
  • Data extraction and quality assessment were performed independently by two reviewers.

    • Main Results:

    • 32 studies were included out of 1239 retrieved papers, with Cariogram being the most frequent model.
    • A statistically significant association was found between CRA model-determined risk and actual caries status/development.
    • Study quality varied, with 19 classified as good, 8 as fair, and 5 as poor.

    Conclusions:

    • There is insufficient evidence to definitively state that standardized CRA models are effective in determining actual caries risk.
    • The predictive validity of standardized CRA models for future caries development remains limited.
    • Further high-quality research is needed to establish the reliability and clinical utility of CRA models.
