Patients' perception of pain during ultrasonic debridement: a comparison between piezoelectric and magnetostrictive scalers.

PURPOSE: To compare patients' perception of discomfort, vibration and noise levels between piezoelectric and the magnetostrictive ultrasonic units during periodontal debridement. METHODS: Periodontal debridement was performed on 75 subjects using a split-mouth design. Two quadrants on the same side were instrumented with a piezoelectric ultrasonic device (EMS Swiss Mini Master® Piezon) and the remaining 2 quadrants were instrumented with a magnetostrictive ultrasonic device (Dentsply Cavitron® SPS™). Subjects marked between 0 and 100 along a visual analog scale (VAS) for each of the 3 variables immediately after treatment of each half of the dentition. Scores of the VAS were compared using a nonparametric test for paired data, the Wilcoxon Signed-Rank test. The level of significance was set at p<0.05. Descriptive statistics included the median and the first and third quartiles as a measure of variation. RESULTS: Mean scores for patient discomfort and vibration were greater for the magnetostrictive device at p=0.007 and p=0.032, respectively. The scores for noise level between the 2 ultrasonic types were almost equal. CONCLUSION: The results show that, on average, patients in this study prefer instrumentation with the piezoelectric as it relates to awareness of associated discomfort and vibration. The results of this study may assist the clinician in the decision over which ultrasonic device may prove more beneficial in decreasing patient discomfort and increasing patient compliance.

Allied dental and dental educators' perceptions of and reporting practices on academic dishonesty.

Highly publicized reports and current research on cheating in dental schools and dental hygiene programs have created a resurgence of proactive measures in the deterrence of academic dishonesty. A majority of administrators and faculty members are of the opinion that cheating does occur at their schools and may have been personally involved with incidents of cheating through observation or student reporting. With the information age and the diverse makeup of today's student body, there may be differences in what is considered academic dishonesty between students and educators. The purpose of this study was to elicit perceptions on those differences, ascertain the number of cheating incidents that educators personally witnessed or about which they received information, and determine how they resolved those incidents. Another aim of this study was to determine if having an honor code, adequate ethics training, honor pledges, dialogue in the classroom, and formal due process policy were related to the number of cheating incidents. Surveys were distributed at the educational program of the American Dental Education Association (ADEA) Section on Dental Hygiene Education at the 2009 ADEA Annual Session & Exhibition. Results show the majority of these educators had had experience with cheating occurrences and believe that there are disparities between students and educators and among cultural groups in defining academic dishonesty. No differences or patterns emerged between academic integrity characteristics and occurrences or reports of cheating.

The prevalence of academic dishonesty in Texas dental hygiene programs.

The media has given much attention to the academic cheating crisis in America. A majority of college students believe that, in today's global environment, it is necessary to cheat in order to get ahead and to compete with their peers. The prevalence and attitudes concerning academic dishonesty of health professions students, including those in medical, dental, and nursing schools, have been extensively researched. No such studies exist in the discipline of dental hygiene. The purpose of this study was to investigate the prevalence of cheating in Texas dental hygiene programs. Four hundred surveys were mailed to twenty Texas dental hygiene schools for graduating students to complete. A total of 289 usable surveys was returned for a response rate of 72.25 percent. Data were analyzed using SPSS with frequencies and chi-square tests. Findings from this study reveal that 86.5 percent of graduating Texas dental hygiene students have cheated a minimum of one time during matriculation. Students identified the demands of what they considered academic overload as the primary justification for cheating behavior.
