Summary
Daily exposure to second-hand smoke (SHS) is linked to fewer remaining teeth in older non-smoking Japanese adults. This study highlights SHS as a risk factor for tooth loss in this population.
Area of Science:
- Gerontology
- Dental Public Health
- Epidemiology
Background:
- Second-hand smoke (SHS) is a known risk factor for various oral diseases.
- The impact of SHS on tooth loss, a consequence of periodontal disease and caries, is not well understood.
- This study investigates SHS exposure and its association with tooth retention in older adults.
Purpose of the Study:
- To evaluate the association between second-hand smoke (SHS) exposure and the number of remaining teeth.
- To assess this relationship among non-smoking older Japanese individuals.
Main Methods:
- Utilized cross-sectional data from the Japan Gerontological Evaluation Study (JAGES) 2013.
- Analyzed data from 18,865 never-smoking respondents aged 65 and above.
- Employed multinomial logistic regression with multiple imputations to analyze SHS frequency and remaining teeth.
Main Results:
- 37.5% of participants reported SHS exposure.
- SHS exposure, particularly "a few times a week" or "almost every day," was significantly associated with fewer remaining teeth after adjusting for age and sex.
- Daily SHS exposure increased the odds of having no teeth (vs. ≥20 teeth) by 1.35 times (OR=1.35, P<0.01).
Conclusions:
- Daily second-hand smoke exposure is significantly associated with a reduction in the number of remaining teeth.
- Findings suggest SHS is a contributing factor to tooth loss in older, non-smoking Japanese individuals.
- Highlights the importance of reducing SHS exposure to maintain oral health in aging populations.

01:29Bias in Epidemiological Studies
1.1K
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

01:15Teeth
1.5K
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...

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

01:25Statistical Methods for Analyzing Epidemiological Data
797
Epidemiological data primarily involves information on specific populations' occurrence, distribution, and determinants of health and diseases. This data is crucial for understanding disease patterns and impacts, aiding public health decision-making and disease prevention strategies. The analysis of epidemiological data employs various statistical methods to interpret health-related data effectively. Here are some commonly used methods:

01:26Assessment of the Mouth
856
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
