TI  - Cementum analysis in cleidocranial dysostosis.
PG  - 253-6
AB  - OBJECTIVE: Cleidocranial dysostosis (CCD) is a skeletal disorder associated with 
      dental anomalies such as failure or delayed eruption of permanent teeth and 
      multiple impacted supernumerary or permanent teeth. Absence of cellular cementum 
      at the root apex is presumed to be one of the factors for failure or delayed 
      eruption. The aim of this study was to analyze the root cementum of 
      supernumerary(S) and permanent teeth (P) of a CCD patient and to compare the 
      findings with those of normal individuals with special emphasis on delayed 
      eruption. MATERIALS AND METHODS: Ground sections of 12 extracted teeth (9S + 3P) 
      of a CCD patient and 12 teeth of normal individuals (5S + 7P) were taken for the 
      study. The sections were longitudinal and 50 microm thick. Root characteristics 
      were recorded with the aid of a light microscope. RESULTS: The absence of apical 
      cellular cementum, increased root resorption and increased percentage of the gap 
      type of cemento-enamel (C-E) junctions were significant findings noted both in 
      the supernumerary and permanent teeth of the CCD patient. CONCLUSION: The 
      presumption of cellular cementum is essential for tooth eruption is not supported 
      by the findings of the present study. Delayed exception could be attributed to 
      various other factors like mechanical obstruction, reduced serum alkaline 
      phosphatase levels etc. Also, the significance of the increased percentage of the 
      gap type of C-E junctions and its role in tooth eruption has to be further 
      evaluated.
