Summary
Children with malocclusion show significant differences in the eruption timing of permanent teeth, particularly canines and premolars. Premature loss of baby teeth may contribute to malocclusion development.
Area of Science:
- Dentistry
- Orthodontics
- Pediatric Dentistry
Background:
- Malocclusion, a common dental issue, can be influenced by various factors.
- Tooth eruption patterns are critical for proper dental development.
Purpose of the Study:
- To investigate differences in the eruption patterns of specific permanent teeth (canines, first and second premolars, second molars) between children with and without malocclusion.
- To explore potential correlations between premature deciduous tooth loss and the development of malocclusion.
Main Methods:
- A cohort of 1758 children (aged 8-13) was randomly selected and categorized by chronological age and malocclusion status.
- Statistical analysis was performed to identify significant differences in tooth eruption timing.
Main Results:
- Statistically significant differences in the eruption of upper and lower canines were observed in 11-year-olds (p<0.01).
- Significant differences were noted for upper first premolars (age 8.5, p<0.05), upper second premolars (age 10, p<0.01), and lower second premolars (age 11, p<0.05).
- Premature loss of deciduous teeth was associated with earlier eruption of permanent successors, potentially contributing to malocclusion.
Conclusions:
- Eruption timing of permanent teeth, including canines and premolars, differs significantly in children with malocclusion.
- Early loss of primary teeth is a potential risk factor for developing malocclusion due to altered permanent tooth eruption sequences.

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...

01:21Tooth 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.

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,...
01:26Assessment 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.

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...

01:16Psychosexual 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.
