Insights

Developmental defects of enamel (DDE) are common in preterm infants, especially those born extremely or very preterm. Intubation and neonatal intensive care unit admission are associated with these enamel defects.

Area of Science:

  • Pediatric Dentistry
  • Neonatology
  • Developmental Biology

Background:

  • Developmental defects of enamel (DDE) in preterm infants are not well understood.
  • DDE may lead to dental caries, poor nutrition, and growth issues.

Purpose of the Study:

  • To evaluate factors associated with DDE in preterm infants.
  • To clarify the prevalence and risk factors for DDE in this population.

Main Methods:

  • Prospective cohort study of 54 preterm infants from birth to 24 months.
  • Dental examinations to identify and categorize DDE.
  • Analysis of perinatal variables and correlation with DDE.

Main Results:

  • 46.3% of preterm infants presented with DDE.
  • Higher incidence of DDE in extremely/very preterm infants, those with very low birth weight, and those admitted to the NICU.
  • Intubation was also a significant risk factor for DDE.

Conclusions:

  • High incidence of incisor enamel defects in preterm infants.
  • Prematurity and local trauma from intubation are linked to DDE.
  • Further research is needed to understand long-term implications.

Introduction to Developmental Psychology

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Three Developmental Domains01:29

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

Lumber Defects01:23

Lumber Defects

Lumber defects, which can affect both the appearance and structural integrity of wood, include a variety of growth and manufacturing flaws. Growth defects such as knots and knotholes occur where branches were once attached to the tree trunk, with knotholes forming when these knots fall out. Other natural defects include decay and insect damage, which compromise the wood's strength and durability.
Shakes are minor fractures that run along or across the wood's annual rings, while wane is...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Theory of Romantic Attachment in Adulthood

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.
