Occlusion was determined using Angle’s classification of malocclusion. The overjet of those who had tongue thrust were measured and compared with the corresponding values of the control subjects. The same orthodontist performed all measurements. Results determined that with p < 0.05, overjet measurements were significantly increased in persons with tongue – thrust when compared to persons who did not have tongue -thrust Which study was conducted? – Correct Answer-Clinical trail

The dental hygienists organizing the events wanted to determine if the fair had an impact on the attendees’ dental knowledge. Attendees were asked to complete a questionnaire prior to visiting five booths and immediately following attendance at the last booth.

It was administered in a pre – and – post-test design. Questionnaire items were in a true or false format. Each item was scored “1” if answered correctly and “0” if answered incorrectly. Items were totaled and overall pre-test scores were compared with overall post – test scores. Statistical analysis was used to determine the difference between the mean scores (p<.01). The pre-test results revealed a mean score of 6.49 and the post-test score revealed a mean score of 7.91.
