Summary
Understanding oral health disparities requires examining parental knowledge, attitude, and practices (KAP). Specific KAP pathways, not general ones, influence children's oral health behaviors and contribute to health inequalities.
Area of Science:
- Public Health
- Health Promotion
- Health Disparities Research
Background:
- Health disparities, particularly in oral health, pose a significant global challenge.
- Effective health promotion strategies necessitate a deep understanding of the factors contributing to these disparities.
Purpose of the Study:
- To investigate the specific behavioral pathways linking parental knowledge, attitude, and practices (KAP) to oral health disparities in preschoolers.
- To differentiate the influence of specific versus generic KAP on oral health homecare and dental attendance.
Main Methods:
- Longitudinal study of 1782 preschoolers (aged 3-6 years) with a 12-month follow-up.
- Oral examinations and parent surveys assessing knowledge, attitude, and practices (KAP) related to oral hygiene, diet, feeding, and dental visits.
- Structural equation modeling (SEM) to analyze the KAP pathways and their mediation effects on oral health outcomes.
Main Results:
- Specific parental knowledge, attitude, and practices (KAP) were linked to children's oral health behaviors, while generic KAP showed no effect.
- KAP pathways partially explained ethnic and socio-economic disparities in oral health.
- Socio-economic status directly impacted dental attendance, whereas ethnicity directly influenced oral health homecare practices, independent of KAP.
Conclusions:
- Behavioral pathways, particularly specific parental KAP, play a crucial role in shaping children's oral health and contribute to health disparities.
- Understanding these pathways offers practical insights for targeted health promotion interventions and policy development to reduce oral health inequalities.

01:28Development 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,...
01:15Teeth
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...

01:27The 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...
01:16Psychosexual Stages of Personality: Oral
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.

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...

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.
