title: Root development of permanent lateral incisor in cleft lip and palate children: a radiographic study.
abstract: OBJECTIVE
  The objective of this study was to compare the root development of lateral incisor on the cleft side with the root development of its contralateral tooth in cleft lip and palate children.
  
  
  METHODS
  Cleft lip and palate wing, Meenakshi Ammal Dental College and Hospital, Chennai, South India.
  
  
  METHODS
  A sample of 96 orthopantamograms of patients with unilateral orbilateral cleft lip and/or cleft palate was selected, regardless of sex and race.
  
  
  METHODS
  Orthopantamograms were analyzed for root development of lateral incisor on the cleft and non cleft side. Associated anomalies like hypodontia, supernumerary teeth, malformed lateral incisors and root development of canine, if present, were recorded.
  
  
  CONCLUSIONS
  Root development of permanent lateral incisor was delayed on the cleft side compared to the non cleft side. There was a statistically significant relationship between levels of root development of lateral incisors on the cleft side within the different study groups(P < 0.05). Incidence of hypodontia increased in proportion to cleft severity. Frequency of missing second premolars, supernumerary teeth and malformed lateral incisors increased in cleft lip and palate patients. Root development of canine showed a slight delay on the cleft side when compared to the canine on the noncleft side.
