Summary
Higher body weight is linked to earlier tooth eruption (TE). This review explores the connection between weight fluctuations and TE timing, crucial for dental health planning and identifying at-risk groups.
Area of Science:
- Pediatric Dentistry
- Orthodontics
- Public Health
Background:
- Tooth eruption (TE) timing is critical for dental treatment planning, especially in orthodontics.
- Growing scientific interest exists regarding body weight fluctuations and their influence on TE.
- Understanding these associations is vital for public health initiatives.
Purpose of the Study:
- To review the existing literature on the relationship between body weight and tooth eruption.
- To synthesize findings on how weight impacts dental development and eruption sequences.
Main Methods:
- Systematic review adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
- Comprehensive online database search using keywords "dental eruption" and "weight".
- Analysis of 14 relevant studies with diverse populations and age ranges.
Main Results:
- Multiple studies indicate a positive correlation between higher Body Mass Index (BMI) and earlier tooth eruption.
- Findings suggest that being overweight or obese is associated with accelerated dental eruption patterns.
- Investigated parameters included surface roughness, color change, and surface fracturing in relation to BMI.
Conclusions:
- A significant association exists between increased body weight and early tooth eruption.
- Identifying populations at risk for altered eruption patterns due to weight is crucial.
- Further research is necessary to elucidate the mechanisms and broader implications of weight-related TE.

01:11Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

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...

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...

01:26Assessment of the Mouth

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.
