Yadira is a one year old girl who visits your office for her routine well child visit. After advising her parents about the importance of brushing twice daily, taking her fluoride supplement (her town has non-fluoridated water) and making an appointment to see their dentist soon, you prepare to perform an oral exam. Yadira is experiencing some age-appropriate stranger anxiety and does not want to let you look in her mouth.
Which of the following approaches would most increase your chance of success with Yadira's oral examination?

A. Have Mom force Yadira's mouth open if she is resisting.
B. Use the knee to knee position for the examination.
C. Use a papoose board to restrain her.
D. Use a mouth mirror to pry the mouth open.
E. Abandon the exam if Yadira cries excessively as the gums can become very erythematous leading to over-diagnosis of gingivitis.
