TI  - Application of the Kvaal method with cone beam for the determination of a local 
      formula for the age estimation of adult African melanoderma subject, Cote 
      d'Ivoire.
PG  - 2-11
AB  - BACKGROUND: Age estimation by invasive dental methods is a destructive, costly 
      and time-consuming approach, whereas, age estimation methods using dental 
      radiographs are simple, non-destructive and provide reliable information. Age 
      estimation by the Kvaal radiographic method has proven to be a reliable method, 
      but possible ethnic variations may limit its uses in other populations. The 
      objective of this study was to reproduce the original Kvaal method with CBCT for 
      the estimation of the age of the adult melano-African subject in Cote d'Ivoire, 
      in order to propose an age estimation formula, specific to our study population, 
      by taking into account the measurements of tooth and pulp ratios. METHODS: A 
      cross-sectional study used 102 radiographic data from a CBCT Planmeca(R) 
      examination in a private dental clinic in Abidjan. It was data from subjects of 
      at least 18 years of age. Dental measurements in length and width of the entire 
      tooth, root and pulp were performed on maxillary central incisors and the 
      different ratios were calculated according to the Kvaal method. The correlation 
      between age and ratios was also assessed. Age estimated using the Kvaal formula 
      was compared to the chronological age. A linear regression equation was developed 
      using ratios and age predictive factors to evaluate the accuracy of the Kvaal 
      formula. RESULTS: In all, a total of 102 radiographs of 102 subjects, of whom 55 
      (53.9%) were females, were analyzed. The median age was 51 years (inter-quartile 
      range [IQR] 41- 58). Using the Kvaal formula, the Standard error of the estimated 
      age was higher in the African melanoderma population compared to the Kvaal 
      population. The new formula derived from that of the Kvaal formula was developed 
      and applied to our study population (Age = 84.7- 114.2 (M) - 29.4 (W - L) gave 
      more than double the standard error of estimated age by Kvaal (26.03). 
      CONCLUSION: Our study showed that the measurements made by Kvaal are reproducible 
      with CBCT and there is a correlation between age and the dental parameters 
      studied. However, the age estimation formula determined by Kvaal et al. is not 
      valid for African melanoderma subjects living in Cote d'Ivoire.
