The purpose of this study was to evaluate patient compliance to postoperati
ve instructions from the oral surgeon. A total of 180 patients who underwen
t minor oral surgical procedures anonymously answered a questionnaire 1 wee
k postsurgery. This questionnaire was used to evaluate how patients remembe
red the mode of transmission of instructions (written, verbal), their compl
iance to the postoperative instructions and to the antibiotic treatment and
their comments. Of the patients, 40% did not remember receiving both writt
en and verbal instructions, 36% remembered only the written instructions. T
welve percent did not comply with the postoperative instructions regarding
mouthwashes and 67% did not comply with the antibiotic prescriptions: 43% t
ook more antibiotics and 31% less, and 4% who did not receive an antibiotic
prescription took them on their own initiative. The academic level of the
patients did not influence patient compliance. Verbal and written recommend
ations worded simply with details are important for patient compliance and
reduced postoperative stress and complaints. Better instructions on antibio
tics use are necessary to ameliorate patient compliance to the antibiotic t
reatment.
