Age Estimation Later in Life: Degenerative Changes Station 3 Remember that dental attrition may be used as an approximate way to gauge age in adults, particularly by using a comparative perspective, differentiating older from younger dentitions. A reliable greatly influences tooth wear. You will put this technique to use by ordering a few sets of dentition by age according to the wear on their teeth Obsene on the following page as an answer page 138, to refresh your tooth database does not exist to attribute states of dental attrition to specific age ranges, partly due to lack of data but also because variation in diet inyour lab, or if a variety of dentitions slackng n your labcolect on reler to Figues A tough C as an altermative, and answer the following questions for each of the specimens. See Figure 620 memory about tooth anatomy, particularly the tootdh layers (enamel and dentin. 1 Are all teth fully erupted? Keep in mind that some may have been lost afher enuption a Specimen A b Specimen B c Specimen C 2 For each specimen, describe whether or not enamel covers the entire occlusal surface of the teeth. Is the enamel worn through in places, exposing the dentin? If so, which teeth show more wear and dentin exposure? (The dentin exposure will appear as darker compared to the white enamel.) a Specimen A b Specimen B c Specimen C 3 How do Specimens A, B, and C compare with each other a in degree of tooth wear? b Are the molars further back in the mouth (more distal) less wom that the more mesial ones? cExplain why this pattern of wear may be observed

Answer 1

2) dental formula for adult human is 2123/2123

3) decidious dental formula for humans for 212/212.
