Item Assessment of the Calibration of Periodontal Diagnosis and Treatment Planning Among Dental Students at Three Dental Schools(American Dental Education Association, 2015-01) Lane, Brittany A.; Luepke, Paul; Chaves, Eros; Maupome, Gerardo; Eckert, George J.; Blanchard, Steven; John, Vanchit; Department of Periodontics and Allied Dental Programs, IU School of DentistryCalibration in diagnosis and treatment planning is difficult to achieve due to variations that exist in clinical interpretation. To determine if dental faculty members are consistent in teaching how to diagnose and treat periodontal disease, variations among dental students can be evaluated. A previous study reported high variability in diagnoses and treatment plans of periodontal cases at Indiana University School of Dentistry. This study aimed to build on that one by extending the research to two additional schools: Marquette University School of Dentistry and West Virginia University School of Dentistry. Diagnosis and treatment planning by 40 third- and fourth-year dental students were assessed at each of the schools. Students were asked to select the diagnosis and treatment plans on a questionnaire pertaining to 11 cases. Their responses were compared using chi-square tests, and multirater kappa statistics were used to assess agreement between classes and between schools. Logistic regression models were used to evaluate the effects of school, class year, prior experience, and GPA/class rank on correct responses. One case had a statistically significant difference in responses between third- and fourth-year dental students. Kappas for school agreement and class agreement were low. The students from Indiana University had higher diagnosis and treatment agreements than the Marquette University students, and the Marquette students fared better than the West Virginia University students. This study can help restructure future periodontal courses for a better understanding of periodontal diagnosis and treatment planning.Item Comparative evaluation of mandibular canal visibility on crosssectional cone-beam CT images: a retrospective study(British Institute of Radiology, 2015) Miles, Mahogany S.; Parks, Edwin T.; Eckert, George J.; Blanchard, Steven B.; Department of Periodontics and Allied Dental Programs, IU School of DentistryOBJECTIVES: The purpose of this study was to determine the visibility of the mandibular canal (MC) in CBCT images and if the visibility of the MC is affected by gender, location and/or age. METHODS: CBCT images were evaluated for the visibility of the MC by a board-certified oral and maxillofacial radiologist, a board-certified periodontist and a periodontics resident. Representative slices were examined for the first premolar (PM1), second premolar (PM2), first molar (M1) and second molar (M2) sites by all examiners. The visibility of the MC was registered as either present or absent. RESULTS: 360 total CBCT cross-sectional images were examined, with the MC identified in 204 sites (56%). Age had a significant effect on MC visibility, but it differed by location: for PM1, age 47–56 had lower visibility than age 65+ (p = 0.0377). Gender also had a significant effect on canal visibility, where females had lower visibility than males overall (p = 0.0178) and had the most pronounced difference for PM1 (p = 0.0054). Location had a significant effect on visibility, but it differed by age and by gender: for age 65+, M2 had lower visibility than PM1 (p = 0.0411) and PM2 (p = 0.0180), while for females, PM1 had lower visibility than M1 (p = 0.0123) and M2 (p = 0.0419). CONCLUSIONS: The MC was visualized only in just over half of the CBCT images. Age, gender and location had significant effects on the visibility.
