Summary
Maintaining natural teeth is crucial for older adults
Area of Science:
- Gerontology
- Public Health
- Dental Health
Background:
- Social participation is vital for older adults' health and well-being.
- Aging societies face challenges of social isolation and loneliness.
- Natural teeth play a role in maintaining social engagement in later life.
Purpose of the Study:
- To investigate the association between retaining natural teeth and social participation in Japanese older adults.
- To estimate the impact of different tooth retention scenarios on social engagement.
- To provide evidence for public health interventions promoting oral health and social well-being.
Main Methods:
- Longitudinal study using data from 24,872 Japanese older adults (2010-2016).
- Employed a longitudinal modified treatment policy approach with targeted minimum loss-based estimation (TMLE).
- Analyzed time-varying exposure (number of teeth) and adjusted for multiple covariates.
Main Results:
- Maintaining 20 or more teeth was associated with an 8% increase in social participation.
- Tooth loss scenarios showed significant reductions in social participation.
- Complete edentulism was linked to an 11% decrease in social participation.
Conclusions:
- Retaining a higher number of natural teeth positively influences social participation among older Japanese adults.
- Preventing tooth loss is a viable strategy to combat social isolation and enhance well-being in aging populations.
- Oral health interventions should be integrated into strategies for promoting active aging and social inclusion.

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...

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

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...

01:04Social Facilitation
32.0K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
