RESUMO
Purpose: To assess the analgesia and side effects of 10 mg oxycodone as compared to 30 mg of codeine phosphate associated with 500 mg of paracetamol after bilateral lower third molar extraction. Methods: This is a prospective, randomized, double-blind study applied to a sample of 16 patients. They were evaluated for seven days postoperatively, and the mean score of the visual analogue scale (VAS) of pain between test and control medications was assessed by the Wilcoxon distribution. The side effects of these medications were assessed by the Q Cochran test. A p value of < .05 was considered statistically significant. Results: The mean score of the VAS of pain was higher in the oxycodone side, where few patients reported the use of rescue analgesic. There was no report of rescue medication in codeine phosphate associated with paracetamol side. The most common side effects reported in both groups, predominantly in patients using the oxycodone, were drowsiness, dizziness, and headache. Conclusion: The use of codeine phosphate associated with paracetamol after the extraction of impacted mandibular third molars is a better choice than oxycodone for controlling postoperative pain.

RESUMO
PURPOSE/OBJECTIVES: The present study aims to evaluate the knowledge of dental students and dentists who work in Primary Health Care (PHC). These are professionals who work in the public basic health units regarding oral cancer prevention, diagnosis, and treatment. METHODS: A cross-sectional and observational Brazilian study was conducted. A survey with 27 questions was carried out regarding the (i) demographic, academic, and professional data of the participants, (ii) attitudes, practices, and self-perception about their training, and (iii) knowledge about oral cancer. With the exception of one question regarding the clinical characteristics of oral cancer, all knowledge answers were graded as correct or incorrect. Grades were assigned to each participant according to their level of knowledge, and scores for each participant were calculated ranging from 1 to 10. Mann-Whitney and Kruskal-Wallis tests were used to examine the difference in the knowledge score of oral cancer according to explanatory variables. The level of significance adopted was 5%. RESULTS: The sample comprised 541 dental students and 82 PHC dentists. Most participants did not consider it appropriate or had not received training for palpation of lymph nodes or for identifying lymphadenopathies associated with oral cancer. Less than 20% of the participants had some kind of practice before and felt safe performing biopsy surgery. The average student score was 7.01 ± 2.15, and the average dentist score was 7.81 ± 1.467. CONCLUSION: Although the scores were satisfactory, most of the participants did not show adequate knowledge about biopsy and palpation of cervical lymph nodes.
