                            Answer: 2
                            Explanation: A compound odontoma is a type of odontogenic tumor that consists of multiple small tooth-like structures (denticles) and resembles the anatomy of normal teeth. In contrast, a complex odontoma has a more disorganized structure and does not resemble normal teeth.

Using "B" film, exposure is 1 R. What is the exposure when "D" film is used 
 1. 1 R
 2. 1/2 R
 3. 1/4 R
 4. 1/8 R
                            Oral Pathology
                            Answer: 3
                            Using "B" film, exposure of 1 R will be reduced to 1/4 R when "D" film is used.
