Summary
This study found that sugary food intake and body composition are linked to dental caries in Romanian children. Reducing sugar and increasing dairy intake is recommended for better oral health.
Area of Science:
- Pediatric Dentistry
- Public Health Nutrition
- Childhood Obesity
Background:
- Rising prevalence of dental caries in children linked to diet and healthcare access.
- Focus on nutritional habits and body composition as contributing factors to early childhood caries.
Purpose of the Study:
- Investigate the prevalence of dental caries in Romanian school-age children.
- Analyze associations between dietary intake, body composition, and dental caries experience.
Main Methods:
- Cross-sectional study of 1100 children (aged 6-10) in two Romanian counties.
- Dental caries assessed using DMFT/dmft indices; dietary habits via food frequency questionnaires.
- Statistical analysis included t-tests, Mann-Whitney U tests, and binary logistic regression.
Main Results:
- Higher DMFT values correlated with increased sugary food consumption and higher BMI/waist circumference.
- Daily cheese consumption associated with lower DMFT values.
- Overall caries prevalence: 79.8% (primary dentition), 63.6% (permanent dentition).
Conclusions:
- Dental caries in Romanian children is significantly associated with sugary food intake and body composition.
- Direct relationship observed between dental caries and childhood obesity indicators (BMI).
- Recommendations include reducing sugary food consumption and increasing dairy product intake.

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 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...

01:26Assessment of the Mouth
1.1K
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.

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...

2.8K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.
