Insights

Children with complete unilateral cleft lip and palate show delayed tooth eruption on the affected side. The maxillary lateral incisor on the cleft side erupts last, altering the typical deciduous tooth sequence.

Area of Science:

  • Pediatric Dentistry
  • Craniofacial Anomalies
  • Dental Development

Background:

  • Complete unilateral cleft lip and palate (UCLP) is a common congenital anomaly.
  • Tooth eruption patterns can be affected by UCLP, impacting oral development.
  • Understanding deciduous tooth eruption chronology in UCLP is crucial for clinical management.

Purpose of the Study:

  • To investigate the timing and order of deciduous tooth eruption in children with UCLP.
  • To compare eruption chronology between teeth on the cleft and non-cleft sides.
  • To identify any sex-specific differences in eruption patterns.

Main Methods:

  • Cross-sectional study design.
  • Involved 435 children aged 0-48 months with complete UCLP.
  • Data collected from a specialized craniofacial anomaly hospital in Brazil.

Main Results:

  • Teeth on the cleft side showed a significantly later mean eruption age compared to the non-cleft side.
  • Statistically significant delays were observed for the maxillary lateral incisor, maxillary cuspid, and mandibular lateral incisor.
  • The maxillary lateral incisor on the cleft side was the last to erupt, disrupting the normal sequence.

Conclusions:

  • The presence of a cleft significantly interferes with the eruption chronology of directly associated deciduous teeth.
  • Delayed eruption and altered sequence highlight the impact of UCLP on dental development.
  • Findings support the need for tailored monitoring of dental development in children with UCLP.

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...

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...
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.
Language Development01:22

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

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,...
