Insights

Nigerian children show earlier primary tooth eruption compared to Arabian and American children, with boys generally erupting teeth sooner than girls. This study establishes crucial baseline data for primary dentition eruption in Nigerian youth.

Area of Science:

  • Pediatric Dentistry
  • Human Growth and Development
  • Anthropology

Background:

  • Limited data exists on primary tooth eruption timelines in African populations, particularly Nigeria.
  • Understanding eruption chronology is vital for assessing child development and identifying potential health issues.

Purpose of the Study:

  • To establish a reference standard for primary tooth eruption in Nigerian children.
  • To provide updated data on the timing and sequence of deciduous tooth emergence.

Main Methods:

  • A cross-sectional study involved 1,013 healthy Nigerian children aged 4–36 months.
  • Data was collected from community health centers and immunization clinics.

Main Results:

  • Boys exhibited earlier eruption of most primary teeth than girls, with a left-side tendency.
  • Girls had a shorter overall eruption duration (first to last tooth).
  • Nigerian children's eruption patterns differed from those in Arabian, American, and Icelandic populations.

Conclusions:

  • Baseline data for primary tooth eruption in Nigerian children has been established.
  • Nigerian children's eruption timing is earlier than Arabian/American counterparts but later than Icelandic children.
  • Findings contribute to pediatric dental health assessments in Nigeria.

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 and...
Development of the Oral Microbiota01:28

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 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 grinding food.
Neurulation01:30

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
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.
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.
Weaning, typically occurring around the age...
