TRUE/FALSE. Write "T" if the statement is true and "F" if it is false 1. Identifications can be of three types: positive, probable, and certain. Answer: False p. 357 2. Comparison of pre- and postmortem radiographs of the teeth is the only way of obtaining a "positive" identification of skeletal remains. Answer: False p. 357 – 360 3. Radiography of various skeletal elements can lead to "positive" identification of skeletal remains. Answer: True p. 358 4. Scalloping of the upper borders of the frontal sinuses is not useful in obtaining a "positive" identification of skeletal remains. Answer: False p. 358 – 359 5. The configuration of trabecular bone seen in radiographs of various skeletal structures can be used in obtaining a "positive" identification of skeletal remains. Answer: True p. 359 6. An unusual healed trauma can aid in obtaining a "positive" identification of skeletal remains. Answer: True p. 360 7. Identification of skeletal remains obtained by combining probabilities using Bayesian statistics cannot result in a positive identification. Answer: False p. 361 8. The imposition of pictures of a person’s face over a skull cannot lead to positive exclusion Answer: False p. 361 9. The point-by-point comparison of a picture of a person’s face superimposed over a skull can lead to a probable identification. Answer: True p. 361 – 364 10.

Answer: False p. 365 12. Age at death can be determined from teeth only from the information on tooth formation and tooth eruption described in Chapter 9. Answer: False p. 366 13. The point-by-point comparison of antemortem radiographs and records from decedents with postmortem examinations of their remains can lead to a positive identification. Answer: True p. 367 – 371 14.
