Summary
Parental oral health knowledge and attitudes in Hong Kong are linked to socioeconomic factors and influence infant oral health practices. Higher income and toothbrushing correlate with better oral hygiene, while milk bottle use increases caries risk.
Area of Science:
- Pediatric Dentistry
- Public Health
- Oral Health Research
Background:
- Infant caries is a significant public health concern, particularly in high-risk populations.
- Understanding the interplay between parental factors and infant oral health is crucial for effective prevention strategies.
Purpose of the Study:
- To investigate the association between parental oral health attitudes/knowledge and sociodemographic factors in Hong Kong infants.
- To explore the link between parental caring behaviors, sociodemographic factors, and infant oral health conditions.
Main Methods:
- Cross-sectional analysis of baseline data from a randomized controlled trial involving 1-year-old high-caries-risk infants in Hong Kong.
- Data collected via structured questionnaires on sociodemographics, parental attitudes/knowledge, and infant oral practices.
- Infant oral examinations assessed dental caries and oral hygiene status.
Main Results:
- Infant caries experience was 1.04%, with unfavorable oral health behaviors observed.
- Parents showed positive attitudes but inadequate knowledge regarding oral health.
- Higher parental education, income, and prior oral health education were linked to better attitudes and knowledge.
- Higher household income and toothbrushing with toothpaste were associated with lower plaque levels.
- Sleeping with a milk bottle was significantly associated with increased caries risk.
Conclusions:
- Parental oral health understanding and attitudes are influenced by sociodemographic background.
- Positive parental attitudes and knowledge correlate with improved infant oral care behaviors.
- Family socioeconomic status and parental practices are key determinants of infant oral health outcomes.

Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Tooth Anatomy
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 grinding food.

Teeth
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 and...

The Oral Microbiota
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Assessment 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.
