In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

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...

Random and Systematic Errors

14.9K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

Systematic Sampling Method01:17

Systematic Sampling Method

13.2K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
Systematic sampling is one of the simplest methods...

Propagation of Uncertainty from Systematic Error

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

Summary

External tooth bleaching significantly reduces plaque and gingivitis in the short term. This systematic review compared bleaching products to placebo, finding notable improvements in oral hygiene markers.

Area of Science:

  • Dental Science
  • Oral Hygiene Research

Background:

  • Plaque and gingivitis indices are key indicators of oral health.
  • External tooth bleaching is a popular cosmetic dental procedure.

Purpose of the Study:

  • To systematically review and evaluate the impact of external tooth-bleaching products on plaque indices.
  • To compare the effects of tooth bleaching on plaque and gingivitis to placebo or no treatment.

Main Methods:

  • Systematic review and meta-analysis of randomized controlled trials.
  • Searched MEDLINE (PubMed) and Cochrane Central Register of Controlled Trials.
  • Included studies focused on adults (≥18 years) without periodontitis.

Main Results:

  • Seven randomized controlled trials were included; six were used in meta-analyses.
  • Bleaching products demonstrated statistically significant reductions in plaque indices (SMD = 0.47, P < 0.001).
  • Significant reductions were also observed in gingivitis indices (SMD = 0.47, P < 0.001) compared to controls.

Conclusions:

  • External tooth bleaching provides short-term benefits by reducing plaque and gingivitis.
  • Long-term effects of tooth bleaching on plaque and gingivitis require further investigation.
