Résumé:
Background: Diamond tips are routinely used in clinical practice, but many undergraduates
neglect to maintain these instruments. Objective: investigate the conditions of diamond tips
used by dental academics. Method: The first step was the application of questionnaires (n =
98), in order to evaluate the characteristics of use, storage, sterilization and conditions of the
diamond tips. At the second stage, three students from each period were randomly chosen,
their instruments were collected and replaced. The collected instruments were analyzed in
Scanning Electron Microscope (SEM). The answers of the questionnaires were submitted to
statistical analysis (SPSS 23), frequency calculations were performed, as well as the chisquare
test (p≤0.05) in order to associate the variables evaluated. Results: the questionnaire
shows that 44.9% used individual packaging; 27.6% used for an interval of 1 to 2 years;
87.8% used 1 to 2x per week; 66.3% affirmed that they were not the same as those of the preclinic,
70.4% used dental care; 73.5% used water, soap and brush for washing; 45.9% used
procedure gloves, cap, mask and lab coat; 51% used air syringe for drying; 39.8% did not
disinfect; 100% used an autoclave; 87.8% reported good conditions of use; 59.2% have
already changed their instruments and 81.6% agree with the self-use. There was no
association between the studied variables and in the images of the SEM it is possible to
observe varying degrees of wear. Conclusion: more stringent protocols and guidelines
regarding the use and maintenance of diamond tips are needed to ensure adequate conditions
for patients to perform treatments.
