Estimation of age done after 25 years with changes in teeth is by
**Core Concept**
The estimation of age based on changes in teeth is a forensic odontology technique used to determine the age of an individual. This method relies on the observation of specific dental changes that occur with age, such as wear and tear, tooth decay, and changes in the periodontal tissues.
**Why the Correct Answer is Right**
The correct answer is based on the fact that the rate of dental wear and tear increases significantly after the age of 25. This is due to the continuous grinding and chewing action of the teeth, which leads to the loss of enamel and dentin. The estimation of age based on dental changes is a reliable method, especially in cases where other methods of age estimation are not feasible. The changes in the periodontal tissues, such as the loss of alveolar bone and the formation of periodontal pockets, also provide valuable information for age estimation.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not specify the correct age range for dental age estimation.
* **Option B:** This option is incorrect because it does not mention the specific changes in teeth that occur with age.
* **Option C:** This option is incorrect because it does not provide a reliable method for age estimation based on dental changes.
**Clinical Pearl / High-Yield Fact**
The estimation of age based on dental changes is a valuable tool in forensic odontology, as it can provide a reliable estimate of age even in cases where other methods are not feasible. However, it is essential to note that this method is not foolproof and should be used in conjunction with other methods of age estimation.
**Correct Answer:** B. After 25 years
