The Difference Between Age Estimates Using Panoramic Radiography Between the Demirjian Method and Willem in Forensic Odontology

Forensic odontology plays a crucial role in the identification process, especially in cases where the age of an individual is a critical factor. One of the methods used to estimate age is based on the stage of dental development, which can be analyzed through panoramic radiography. The two popular methods used are the Demirjian and Willem methods. In this article, we will discuss the differences between these two methods and their accuracy in age estimates using panoramic radiography.

Understanding the Importance of Age Estimation in Forensic Odontology

Age estimation is a vital aspect of forensic science, as it helps investigators to determine the identity of an individual, especially in cases where the body is decomposed or fragmented. The accuracy of age estimation is crucial in ensuring that justice is served. In forensic odontology, age estimation is typically done by analyzing the stage of dental development, which can be assessed through panoramic radiography.

The Demirjian and Willem Methods: A Comparison

The Demirjian and Willem methods are two of the most commonly used methods for age estimation based on panoramic radiography. Both methods involve assessing the stage of tooth development, but they differ in their approach and accuracy.

The Demirjian Method

The Demirjian method is a widely used method for age estimation based on panoramic radiography. This method involves assessing the stage of tooth development by analyzing the calcification of teeth. The method is based on a tooth development atlas, which provides a detailed description of the stages of tooth development. The Demirjian method has been shown to be accurate in estimating age, especially in children aged 7-12 years.

The Willem Method

The Willem method is another popular method for age estimation based on panoramic radiography. This method also involves assessing the stage of tooth development, but it uses a different approach than the Demirjian method. The Willem method is based on a tooth development atlas, but it uses a different set of criteria to determine the stage of tooth development. The Willem method has been shown to be less accurate than the Demirjian method in estimating age, especially in children aged 7-12 years.

A Comparative Study of the Demirjian and Willem Methods

A recent study compared the accuracy of the Demirjian and Willem methods in age estimates using panoramic radiography. The study involved 60 panoramic photos of 30 male patients and 30 female patients aged 7-12 years. The results showed that the average chronological age of the sample was 9.78 years, while the age of teeth based on the Demirjian method was 9.89 years, and the age of teeth based on the Willem method was 9.51 years.

Further Analysis: Accuracy and Differences in Age and Gender

Further analysis of the study showed that the Demirjian method tends to overestimate age by 0.11 years, while the Willem method underestimates age by -0.27 years. The study also found that there were no significant differences between chronological age and dental age based on the Demirjian method in men and women in each age group (7-12 years). The Willem method also showed similar results, except for men in the age group 7, 8, 9, 10, and 12 years and women in the age group 7-11 years.

Conclusion

Based on the results of this study, it can be concluded that the Demirjian method is more accurate than the Willem method in age estimates using panoramic radiography in children aged 7-12 years. This is because the Demirjian method has a higher level of accuracy in detecting the stage of tooth development at that age.

The Importance of Using the Right Method

The choice of the right method in age estimates is very important, especially in the context of forensic odontology. The use of inaccurate methods can cause incorrect conclusions and impact on the investigation and justice process.

Recommendation

Based on the results of this study, the following recommendations can be made:

The use of the Demirjian method is recommended for age estimation in children aged 7-12 years based on panoramic radiography.
Further research is needed to examine the accuracy of the two methods in a broader age group and in different contexts.
It is essential to always consider other factors that can affect tooth development, such as genetic factors, nutrients, and diseases, when estimating age.

Limitations of the Study

This study has several limitations. Firstly, the study only involved 60 panoramic photos of 30 male patients and 30 female patients aged 7-12 years. Secondly, the study only compared the accuracy of the Demirjian and Willem methods in age estimates using panoramic radiography. Further research is needed to examine the accuracy of the two methods in a broader age group and in different contexts.

Future Directions

Future research should focus on examining the accuracy of the Demirjian and Willem methods in a broader age group and in different contexts. Additionally, further research is needed to examine the effect of other factors that can affect tooth development, such as genetic factors, nutrients, and diseases, on age estimation.

Conclusion

In conclusion, this study highlights the importance of using the right method in age estimates using panoramic radiography. The Demirjian method is more accurate than the Willem method in age estimates using panoramic radiography in children aged 7-12 years. The choice of the right method is crucial in ensuring that justice is served. Further research is needed to examine the accuracy of the two methods in a broader age group and in different contexts.
