Exercise No. 406
Subject Code: 430
Pediatric Dentistry

The 15 questions for this exercise are based on the article Association between body mass index and dental age in Hispanic children on pages 59-58. This exercise was developed by Charles Martello, DDS, MAGD, in association with the General Dentistry Self-Instruction committee.

Reading the article and successfully completing this exercise will enable you to:

  • identify the association between body mass index (BMI) and craniofacial development;
  • understand that the dentist may choose to employ a conservative restorative approach if premature tooth exfoliation is anticipated; and
  • recognize the importance of timely orthodontic referral for patients with premature dental development.

Answers for this exercise must be received by June 30, 2018.
