RESUMO
Most dental schools lack a module on prescription writing in pharmacology. This study assessed the prescription writing skills of a group of Malaysian dental students at the end of their undergraduate training program. A quantitative study of a two-group posttest experiment was designed, and thirty-seven fifth-year (final-year) dental students were divided into two groups (A [n=18] and B [n=19]). Group A received a didactic lecture on how to write a complete prescription, while Group B served as a control group. For prescription writing, three standardized dental scenarios with a diagnosis of irreversible pulpitis associated with a child and a pregnant woman and periapical pulpitis for an adult man were administered. Thus, a total of 111 prescriptions (Group A [n=54] and Group B [n=57]) were collected. Twelve elements in each prescription were assessed by frequency and a chi-square test. Improvements in eight out of the twelve elements were observed in prescriptions written by students in Group A. The significantly improved elements were provision of the symbol R(x) (39.8 percent) (p<0.001), inclusion of the prescriber's signature (75.3 percent) (p<0.001), inclusion of the date with the prescriber's signature (54.6 percent) (p<0.001), and inclusion of the prescriber's registration (30.5 percent) (p<0.001). Overall, Group A gained almost a 50 percent improvement in writing complete prescriptions due to the intervening lecture. It appeared a traditional lecture led to the more accurate writing of a complete prescription. It was suggested that a module on prescription writing be added to the school's pharmacology curriculum, so that dental graduates will be competent in prescription writing for the sake of their patients' health.
