1. Identifications can be of three types: positive, probable, and certain.
Answer:       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:       p. 357 – 360

3. Radiography of various skeletal elements can lead to "positive" identification of skeletal remains.
Answer:       p. 358

4. Scalloping of the upper borders of the frontal sinuses is not useful in obtaining a "positive" identification of skeletal remains.
Answer:       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:       p. 359

6. An unusual healed trauma can aid in obtaining a "positive" identification of skeletal remains.
Answer:       p. 360

7. Identification of skeletal remains obtained by combining probabilities using Bayesian statistics cannot result in a positive identification.
Answer:       p. 361

8. The imposition of pictures of a person’s face over a skull cannot lead to positive exclusion
Answer:       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.

12. Age at death can be determined from teeth only from the information on tooth formation and tooth eruption described in Chapter 9.
Answer:       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:       p. 367 – 371

14. Antemortem and postmortem radiographs of amalgams and other dental appliances are used by forensic odontologists to obtain a positive identification.
Answer:       p. 369 – 371

Answer:       p. 371
