Insights

Gestational age significantly impacts primary teeth eruption timing in Indian children. Preterm infants experience delayed tooth eruption, especially central incisors and second molars, even after adjusting for prematurity.

Area of Science:

  • Pediatric Dentistry
  • Developmental Biology
  • Public Health

Background:

  • Primary teeth eruption is a key developmental milestone.
  • Factors influencing eruption include genetics, gender, and socio-economic status.
  • The impact of gestational age on primary tooth eruption in India remains understudied.

Purpose of the Study:

  • To investigate the influence of gestational age on the timing and sequence of primary teeth eruption.
  • To assess primary tooth eruption patterns in Indian children from Mysore.

Main Methods:

  • Prospective longitudinal cohort study involving 150 newborns.
  • Follow-up from birth to 36 months with regular dental assessments.
  • Statistical analysis using descriptive statistics, t-tests, and Chi-squared tests.

Main Results:

  • Mandibular central incisors were the first teeth to erupt.
  • Preterm infants showed a significant delay in overall tooth eruption chronologically.
  • Adjusting for prematurity revealed significant delays in central incisor and second molar eruption.

Conclusions:

  • Gestational age is strongly associated with primary teeth eruption timing.
  • Gestational age is a significant predictor of delayed primary tooth eruption in Mysore children.

Teeth01:15

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...

Tooth Anatomy01:21

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...

Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Psychosexual Stages of Personality: Oral01:16

Psychosexual 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.

Assessment of the Mouth01:26

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.
