Outcomes and stability in patients with anterior open bite and long anterior face height treated with temporary anchorage devices and a maxillary intrusion splint

Temporary skeletal anchorage devices now offer the possibility of closing anterior open bites and decreasing anterior face height by intruding maxillary posterior teeth, but data for treatment outcomes are lacking. This article presents outcomes and posttreatment changes for consecutive patients treated with a standardized technique

Dentofacial disharmony: Psychological status of patients seeking treatment consultation

A sample of 194 patients whose dentofacial disharmonies were severe enough to warrant an orthognathic surgical treatment option completed the SCL-90-R, a 90-item assessment tool used to measure current level of psychological distress. Two global and nine primary dimension scores of psychological distress were computed. The average interpersonal sensitivity, psychoticism, and obsessive-compulsive dimension scores were higher than the nonpsychiatric patient population norms for both males and females, but the confidence intervals for these dimensions were still in the upper end of the normal range of functioning (< 1 SD above the normative mean). No statistically significant differences by gender or age group were observed. Over 15% of the patients were clinically elevated on obsessive-compulsive behavior, interpersonal sensitivity problems, hostility, paranoid ideation, and psychoticism; and 24.7% qualified as a positive diagnosis for a psychiatric disorder. It appears that a surprisingly large number of individuals with dentofacial disharmonies who are seeking treatment consultation are experiencing a level of psychological distress that warrants intervention

Learn-A-Prep II as a Predictor of Psychomotor Performance in a Restorative Dentistry Course

This investigation assessed whether early student performance with a dental handpiece on a didactic training aid known as the Learn-A-Prep II (LAP II) was predictive of performance on subsequent practical examinations in a preclinical restorative dentistry course. Eighty-one first-year students were given initial handpiece training and formative feedback using the LAP II and were then instructed to independently prepare four LAP II patterns within the pattern lines and at a specified depth. Performance on the LAP II was compared with the summative assessment on two subsequent amalgam preparation practical examinations given at the middle (Class II) and end (Complex) of the course. Pattern preparation within the lines did not significantly improve the likelihood of receiving an A or B on the Class II practical (p=0.53) or on the Complex practical (p=0.37). Students who had an acceptable depth on the LAP II were 3.73 times more likely to receive an A or B on the Class II practical than those students who did not have acceptable depth (p=0.03). Performance at an acceptable depth did not significantly improve the likelihood of receiving an A or B on the Complex practical (p=0.15). The LAP II may aid in identification of students who would benefit from early intervention with additional focused instruction

The hierarchy of stability and predictability in orthognathic surgery with rigid fixation: an update and extension

A hierarchy of stability exists among the types of surgical movements that are possible with orthognathic surgery. This report updates the hierarchy, focusing on comparison of the stability of procedures when rigid fixation is used. Two procedures not previously placed in the hierarchy now are included: correction of asymmetry is stable with rigid fixation and repositioning of the chin also is very stable. During the first post-surgical year, surgical movements in patients treated for Class II/long face problems tend to be more stable than those treated for Class III problems. Clinically relevant changes (more than 2 mm) occur in a surprisingly large percentage of orthognathic surgery patients from one to five years post-treatment, after surgical healing is complete. During the first post-surgical year, patients treated for Class II/long face problems are more stable than those treated for Class III problems; from one to five years post-treatment, some patients in both groups experience skeletal change, but the Class III patients then are more stable than the Class II/long face patients. Fewer patients exhibit long-term changes in the dental occlusion than skeletal changes, because the dentition usually adapts to the skeletal change

Short-term Recovery after Orthognathic Surgery: A Medical Daily Diary Approach

This study assessed the utility of a quality-of-life diary for the assessment of postoperative recovery following orthognathic surgery. A 20-item daily recovery diary was designed to assess the patients’ perception of recovery in 4 domains (postoperative sequelae; pain/discomfort; oral function; daily activities) during each of the first 90 days after surgery. Fifteen of 185 patients who had agreed to participate did not return any portion of the diary. Of the remaining patients, 87% returned the full 90 days requested. Younger patients were more likely to complete the entire protocol (P = 0.01). At 30 days, a lower percentage, in general, of patients who completed all 90 days reported recovery in oral function and general activity compared with those who did not complete all diary days. This study confirms that patients will cooperate with the completion of structured medical / health-related quality-of-life diaries during the first few months after orthognathic surgery. Information from such diaries would be valuable to patients deciding on treatment options and to the clinicians counseling them

Gender Issues in Clinical Dental Education

In spring 2011, a study was initiated to investigate the nature and extent of gender issues in clinical dental education at the University of North Carolina at Chapel Hill School of Dentistry. Surveys were sent to 236 dental students in the second, third, and fourth years; eighty-six (36.4 percent) responded. Surveys were also sent to seventy-one full-time dental faculty members who had clinical contact with students, and thirty-four (47.9 percent) responded. Of the student respondents, fifty-one were female and thirty-five were male; the faculty respondents were ten women and twenty-four men. A significantly greater proportion of female than male student respondents reported that issues related to gender affected clinical training. The female students also responded that mentorship was less available and less in content for them compared to males, and significantly more female than male students reported lower self-confidence in clinical settings. Among faculty respondents, a higher proportion of women than men reported insufficient awareness of gender issues. These faculty members also reported thinking that female students showed more empathy toward patients than males. Both faculty and student respondents said that female faculty members received less respect from students than did male faculty members. Forty-eight percent of the students reported experiencing or witnessing gender-based prejudice in clinical settings, and 7.0 percent reported experiencing or witnessing unwelcome sexual advances or conduct. A more robust study to include other dental institutions is needed. With confirmation of specific gender issues, corrective measures could be recommended to improve the climate for both females and males in the clinical component of dental education

Postdischarge Nausea and Vomiting Remains Frequent After Le Fort I Osteotomy Despite Implementation of a Multimodal Antiemetic Protocol Effective in Reducing Postoperative Nausea and Vomiting

Purpose—To assess the prevalence of postdischarge nausea and vomiting (PDNV) after Le Fort I osteotomy with and without the use of a multimodal antiemetic protocol shown to decrease postoperative nausea and vomiting (PONV). Materials and Methods—Consecutive patients undergoing Le Fort I osteotomy with or without additional procedures at a single academic institution formed the intervention cohort for an institutional review board–approved prospective clinical trial with a retrospective comparison group. The intervention cohort was managed with a multimodal antiemetic protocol. The comparison group consisted of consecutive patients who underwent similar surgical procedures at the same institution before protocol implementation. All patients were asked to complete a postdischarge diary documenting the occurrence of nausea and vomiting. Those who completed the diaries were included in this analysis. Data were analyzed with the Fisher exact test and the Wilcoxon rank sum test. A P value less than .05 was considered significant. Results—Diaries were completed by 85% of patients in the intervention group (79 of 93) and 75% of patients in the comparison group (103 of 137). Patients in the intervention (n = 79) and comparison (n = 103) groups were similar in the proportion of patients with validated risk factors for PDNV, including female gender, history of PONV, age younger than 50 years, opioid use in the postanesthesia care unit (PACU), and nausea in the PACU (P = .37). The prevalence of PDNV was unaffected by the antiemetic protocol. After discharge, nausea was reported by 72% of patients in the intervention group and 60% of patients in the comparison group (P = .13) and vomiting was reported by 22% of patients in the intervention group and 29% of patients in the comparison group (P = .40). Conclusion—Modalities that successfully address PONV after Le Fort I osteotomy might fail to affect PDNV, which is prevalent in this population. Future investigation will focus on methods to minimize PDNV
