Learning objectivesAfter completing this course, the participant will be able to:1. Discuss the accuracy of patients’ self reports of headgear wear.2. Describe effects of sucking behavior on dental arch dimensions

and occlusal relationships.3. Assess the usefulness of mandibular shape for growth predic-

tion.4. Describe the effects of the headgear-activator appliance in

growing Class II patients.

Article 1. Accuracy of patient reporting as an indication ofheadgear compliance, by William A. Cole1. Which best characterizes this quotation? “The extent to which a

person’s behavior (in terms of taking medications, followingdiets, or executing lifestyle changes) coincides with medical orhealth advice.”a. It describes treatment outcomes.b. It explains poor cooperation.c. It is a definition of compliance.d. It refers to the internal locus of control.

2. What data were obtained in this study?a. A comparison of reported headgear wear to treatment out-

come.b. Measured headgear wear during the first 3 months of

headgear use.c. Reported and measured hours of headgear wear.d. Total reported headgear wear for the entire period of active

treatment.3. What did the data show?

a. Most subjects overreported the amount of time they wore theheadgear.

b. No one underreported the amount of time he or she wore theheadgear.

c. Some subjects did not wear the headgear at all.d. The average amount of compliance was 30.3%.

4. What percentage of subjects reported reasonably accurate head-gear compliance?a. 31%.b. 58%.c. 69%.d. 84%.

Article 2. Duration of nutritive and nonnutritive sucking behav-iors and their effects on the dental arches in the primarydentition, by John J. Warren and Samir E. Bishara5. How were data collected for this study?

a. The sucking behavior of each child was assessed longitudi-nally, beginning at birth.

b. Data on sucking behavior were obtained with a parentalquestionnaire when the occlusal examination was performed.

c. The study was limited to an analysis of data from breast-fedchildren.

d. Assessment of occlusal relationships and arch dimensionswas obtained from a clinical examination.

6. What effect did sucking behavior have on the dentition?a. Breast-feeding had no effect on arch dimensions regardless

of the duration.b. Breast-feeding longer than 6 months was associated with

excessive overjet.c. Pacifier habits had no effect on arch dimensions regardless of

the duration.d. Pacifier habits longer than 6 months were associated with

excessive overjet.7. Which was NOT associated with pacifier habits of 36 months or

more?a. Decreased overbite.b. Excessive overjet.c. Greater mandibular arch widths.d. Posterior crossbite.

8. Pacifier habits were associated with increased overjet, narrowedmaxillary arch widths, and elongated maxillary arch depths.Digit habits were associated with posterior crossbite, increasedmandibular arch width, and shallower palatal depths.a. The first statement is true; the second is false.b. The first statement is false; the second is true.c. Both statements are true.d. Both statements are false.

Article 3. Evaluation of antegonial notch depth for growthprediction, by Ronald P. Kolodziej, Thomas E. Southard, Karin A.Southard, John S. Casko, and Jane R. Jakobsen

9. What is the possible significance of the antegonial notch?a. Antegonial notch depth is directly correlated with Class II

malocclusion.

426

b. Antegonial notch depth may be related to the direction ofmandibular growth.

c. Mandibles with a forward growth tendency show surfaceapposition under the mandibular angle.

d. The antegonial notch is only evident in persons with aforward mandibular growth tendency.

10. Which cephalometric variable changed the least with growth?a. Antegonial notch depth.b. A-point vertical.c. Pogonion horizontal.d. SN-MP angle.

11. Which cephalometric variable showed a clinically importantcorrelation with antegonial notch depth?a. A-point horizontal.b. None.c. SN-MP angle.d. Y-axis.

12. What did the authors of this study conclude?a. Antegonial notch depth applies equally well to all patients as

a growth predictor.b. Antegonial notch depth does not sufficiently predict facial

growth in the general population.c. The sample size was all that was required for appropriate

statistical power.d. There was a strong relationship between decreasing notch

depth and vertical jaw growth.

Article 4. Growth and treatment changes in patients treated

with a headgear-activator appliance, by Margareta Bendeus,Urban Hagg, and Bakr Rabie

13. What treatment change was observed?a. Overbite did not change.b. The appliance produced added mandibular growth.c. The skeletal treatment effect was limited to the maxilla only.d. Vertical growth of the midface was enhanced.

14. What reason is given for a longer treatment time?a. Maxillary growth is more likely to be favorably affected.b. Longer treatment time improves the chances for maxillary

catch-up growth.c. It takes longer for the appliance to have an effect on

mandibular growth.d. Longer treatment time will result in increased lower facial

height.15. How did the mandible contribute to the improvement of jaw

relationship?a. It was caused by significant additional growth in length.b. It was due to posterior rotation.c. It was the result of forward positioning.d. It was similar to normal growth.

16. What was the dental effect of the appliance?a. Eruption of the maxillary molars was restrained.b. Incisors erupted more than did the molars.c. Overbite showed little change.d. Overjet reduction was much greater than jaw base improve-

ment.
