Summary

Dental development in children with clefts shows no significant differences in girls. However, boys with unilateral cleft lip and palate exhibit delayed dental maturity compared to unaffected peers.

Area of Science:

  • Dentistry
  • Orthodontics
  • Pediatric Dentistry

Background:

  • Cleft lip, cleft palate, or both are congenital conditions affecting facial development.
  • Dental development and maturation can be influenced by various genetic and environmental factors.

Purpose of the Study:

  • To investigate the relationship between chronological age and permanent tooth development in children with cleft lip, palate, or both.
  • To compare dental maturation in cleft patient groups with a control group of children without clefts.

Main Methods:

  • Utilized the Demirjian et al. (1973) method for assessing dental maturation.
  • Evaluated panoramic radiographs of 107 Caucasian children (4-12 years) with bilateral cleft lip and palate (BCLP), unilateral cleft lip and palate (UCLP), or cleft palate only (CP).
  • Calculated dental maturation scores for permanent mandibular teeth and compared them to a non-cleft control group (Loevy, 1983).

Main Results:

  • No significant difference in dental maturity was found between girls with any type of cleft and the control group.
  • A significant difference in dental maturity was observed in boys when all cleft groups were combined.
  • Boys with BCLP or CP alone showed no significant difference from controls, but boys with UCLP exhibited a highly significant delay in dental maturity.

Conclusions:

  • Dental maturation in girls with clefts is comparable to that of non-cleft individuals.
  • Boys with unilateral cleft lip and palate demonstrate a distinct delay in dental maturation compared to unaffected children.
  • The specific type of cleft may influence the pattern of dental development in boys.
