Comparative anchorage maintenance between the intercanine coil, lip bumper, and mandibular cervical traction during cuspid retraction

Thesis (M.Sc.D.)--Boston University School of Graduate Dentistry, 1972 (Orthodontics)Bibliography included.The present study was undertaken to compare the efficiency of three different biomechanical mechanisms in preserving mandibular molar anchorage. Thirty-five patients were treated with intercanine coil, lip bumper, 9r mandibular cervical traction through the end of cuspid retraction. Midtreatment cephalograms were then taken. Superimposition of these midtreatment cepbalograms with the pretreatment cephalograms provided the author with the net mesial or distal movement of the mandibular first molar in each case. The data obtained from each case was accordingly placed in the appropriate biomechanical group. Each group was then statistically related to one another by means of the Mann-Whitney U Test. It was found that a stastically significant difference existed between lower cervical traction and the intercanine coil. The confidence level obtained (P < .02) indicated that less than two cases out of a hundred had a chance of coming from the same population. This data also showed a mean increase in mandibular anchorage with lower cervical traction ( +.062 mm. gained) indicating that there may be very good possibilities for this system to be used in orthodontic cases when anchorage is of a critical nature

Do Higher Exam Grades Predict Higher Standards of Success and More Test Anxiety?

The current study used a short-term, prospective design to examine the relationships among test anxiety, test performance, students' standards for success, and students' test selfefficacy (i.e., performance expectancies). College freshmen (N = 171) enrolled in an introductory psychology course during their first semester of college completed Time 1 questionnaires about one week before their first in-class exam. One hundred two participants (56% of Time 1 participants) completed Time 2 questionnaires up to one week after learning the results of their test scores and about two weeks prior to their second in-class exam. Irrelevant Thinking subscale scores on the Revised Test Anxiety Scale (RTA) predicted second exam scores, even after controlling for first exam scores. High exam scores predicted increases in personal standards but not in perceived instructor's standards, even after controlling for prior standards. High exam scores also predicted increases in personal standards and test self-efficacy (belief in one's ability to perform well on a test) in the low test anxious group but not in the high test anxious group. This study supports past research in so far as it provides evidence that test anxiety predicts lower test performance, but test performance does not predict changes in test anxiety. Among two test anxiety groups (low vs. high), the relationship between exam scores and standards for success as well as the relationship between exam scores and self-efficacy are explored. The implications are discussed in terms of possible self-handicapping behaviors and self-focused attention.B.A. (Bachelor of Arts
