INTRODUCTION: As dental implant surgery is becoming increasingly popular, it has become one of the causes for the hypesthesia of the inferior alveolar nerve, along with other surgical procedures, such as a third molar extraction. In addition, it tends to cause legal problems between the operator and patient. Therefore, there must be a proper method that is reliable, objective and economical to assess the nerve impairment. For this reason, an attempt was made to use an Electric Pulp Tester to assess inferior alveolar nerve block anesthesia. MATERIALS AND METHODS: Thirty patients were tested. Electric pulp testing of the lower jaw skin was performed at the three different times, before anesthesia, at the onset of sensory changes and after 15 minutes waiting from the onset, and on the 10 points of the chin, which produced 10 sections on the skin area. RESULTS: Twenty seven patients (90%) could feel the electric stimulus on the chin at all 10 points before local anesthesia and the scores represent the statistical differences between the right and left points except R4 and L4. After anesthesia, the difference between the right and left points (L3-R3, L4-R4, L5-R5) increased significantly with time but two points (L2, R2) showed no significant difference. The scores on the left chin (L3, L4, L5) increased, whereas the other points (R1-R5, L1, L2) showed no significant differences. CONCLUSION: This study highlights the potential clinical use of an electric pulp tester for an assessment of inferior alveolar nerve impairment.

Among the treatment options for BRCA mutation carriers, risk reducing surgery is the most effective. However, this procedure has been rarely performed in Korea. Interestingly, our case showed double heterozygosity for BRCA1 and BRCA2 mutations. The patient was diagnosed with left renal cancer and left breast cancer at 45-years-of-age, 4 years before risk reducing surgery. The patient received left radical nephrectomy and left partial mastectomy with axillary lymph node dissection. After pretest counseling, the patient underwent genetic testing that identified BRCA1 and BRCA2 mutations. After post-test counseling, the patient decided on intensive surveillance. At 49-years-of-age, the patient was newly diagnosed with contralateral breast cancer. Treatment options were discussed once again. We performed bilateral total mastectomy with immediate reconstruction and prophylactic bilateral salpingo-oophorectomy after multidisciplinary discussion. The patient has been satisfied with the results of surgery. We think this procedure is a recommendable treatment option for BRCA mutation carriers.
