Summary
Periodontitis progression varies significantly, with average annual attachment loss of 0.1mm and tooth loss of 0.2 teeth. Geographic location impacts progression, but age and gender do not significantly influence it.
Area of Science:
- Periodontology
- Dental Public Health
Background:
- Periodontitis progression rate is crucial for disease classification.
- Existing evidence is unclear, and no systematic reviews have been conducted.
Purpose of the Study:
- To systematically review the progression of periodontitis in adults.
- To assess progression in terms of clinical attachment loss, radiographic bone loss, and tooth loss.
Main Methods:
- Systematic review and meta-analysis of prospective, longitudinal observational studies.
- Included studies had a follow-up of at least 12 months.
- Searched MEDLINE, EMBASE, LILACS, and OpenGrey databases.
Main Results:
- 16 studies with over 8,600 participants were included.
- Mean annual attachment loss was 0.1mm; mean annual tooth loss was 0.2 teeth.
- Geographic location showed significant differences in attachment loss, with higher rates in Sri Lanka and China.
Conclusions:
- Periodontitis progression varies considerably within and between populations.
- Current evidence does not support differentiating periodontal diseases based on attachment level change progression.
- Further research is needed due to study limitations and heterogeneity.

Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that...

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.

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...

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...

The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.
Line loss impacts power delivery efficiency in a balanced three-phase circuit. The symmetry in such a circuit simplifies the...

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.
