 An alternative approach using bitewing screening with selected periapical views is suggested as a method of minimising radiation dose to the patient while maximizing diagnostic yield.Contrary to advice that emphasises only conducting radiographs when in the patient's interest, recent evidence suggests that they are used more frequently when dentists are paid under fee-for-service 

Accurate positioning is of utmost importance to produce diagnostic radiographs and to avoid retakes, hence minimizing the radiation exposure of the patient.The requirements for ideal positioning include
