RESUMO
Context: There is a need to evaluate the quality of postgraduate dissertations of dentistry submitted to university in the light of the international standards of reporting. Aims: We conducted the review with an objective to document the use of sampling methods, measurement standardization, blinding, methods to eliminate bias, appropriate use of statistical tests, appropriate use of data presentation in postgraduate dental research and suggest and recommend modifications. Settings and Design: The public access database of the dissertations from Rajiv Gandhi University of Health Sciences was reviewed. Subjects and Methods: Three hundred and thirty‑three eligible dissertations underwent preliminary evaluation followed by detailed evaluation of 10% of randomly selected dissertations. The dissertations were assessed based on international reporting guidelines such as strengthening the reporting of observational studies in epidemiology (STROBE), consolidated standards of reporting trials (CONSORT), and other scholarly resources. Statistical Analysis Used: The data were compiled using MS Excel and SPSS 10.0. Numbers and percentages were used for describing the data. Results: The “in vitro” studies were the most common type of research (39%), followed by observational (32%) and experimental studies (29%). The disciplines conservative dentistry (92%) and prosthodontics (75%) reported high numbers of in vitro research. Disciplines oral surgery (80%) and periodontics (67%) had conducted experimental studies as a major share of their research. Lacunae in the studies included observational studies not following random sampling (70%), experimental studies not following random allocation (75%), not mentioning about blinding, confounding variables and calibrations in measurements, misrepresenting the data by inappropriate data presentation, errors in reporting probability values and not reporting confidence intervals. Few studies showed grossly inappropriate choice of statistical tests and many studies needed additional tests. Conclusions: Overall observations indicated the need to comply with standard guidelines of reporting research.
RESUMO
The key dictum to build reliability (and validity) for any assessment is to have multiple tests on multiple content areas by multiple examiners using multiple tools in multiple settings. Moreover, stress coping skills will have positive impact on all the domains which in turn give a boost to positive tendencies, viz., increasing their attentiveness in class, concentration, and learning and thereby reduce the altered performance due to stress. As a result, the CIV (noise in the assessment) is reduced and hence the validity of assessment is improved. Psychologist and Psychometricians are to be appointed in every institute.
RESUMO
Background: Gibberish meditational technique claims to reduce the stress and decrease unnecessary thought currents helping the practitioner to be relaxed and attentive. Aims & Objective: The aim of the present study was to know the effect of this technique, just prior to a learning session, on the student’s academic performance, perception and pulse rate. Material and Methods: 87 dental students were divided into two groups by systematic allocation. One group practiced Gibberish meditation technique and the other was control group. Both groups attended a one hour lecture as a part of their regular lecture series. Results: Results did not show any significant difference between the groups in academic performance, although meditation group scored higher. Significant number of students in gibberish group reported to be more attentive, comfortable, relaxed and had better memory and had significant reduction in mean pulse rate. Students expressed a feeling of relaxation and of having a fun filled learning atmosphere after meditation. Conclusion: This simple and easy technique of meditation could be adopted to enhance student learning.
