چکیده: (60 مشاهده)
Background and Aim: The London Atlas is a recently introduced method of age estimation using orthopantomographs (OPGs), which has not been tested in the Kerala population. Thus, the present study was carried out to assess and compare the chronological age of the participants with the estimated age using the London Atlas method.
Materials and Methods: A retrospective cross-sectional study was conducted to evaluate the London Atlas method for age estimation using OPGs of 220 healthy individuals (60.5% females and 39.5% males) between 5 to 23.99 years collected from the archives. The chronological age of the participants was calculated using their date of birth. Data were analyzed by paired t-test and Pearson’s correlation coefficient (alpha=0.05). The intra-examiner reliability was analyzed using the Cohen’s kappa.
Results: A statistically significant difference existed between the chronological age and the age estimated using the London Atlas method (t-value=-8.301, P<0.05). A positive statistically significant correlation was found between the estimated age using the London Atlas method and the chronological age in all age groups (Pearson’s correlation coefficient of 0.989 in males and 0.985 in females, P<0.05). The goodness of fit evaluation of the London Atlas method for prediction of actual age indicated that the model can fit with R2 value of 0.975.
Conclusion: The London Atlas method showed a strong positive correlation with actual chronological age while at the same time a statistically significant difference existed between the actual age and estimated age. There was no difference in age estimation between the two genders.
