For two weeks, cold冷的 /koʊld/ air or water had caused病因 /kɔzd/ a sharp尖锐的 /ʃɑrp/ ache疼痛 /eɪk/ in Jack's upper上部的 /ˈəpər/ jaw下颌 /ʤɔ/. He changed his diet饮食 /daɪət/ and chewed咀嚼 /ʧud/ on the left, but a sleepless night sent him to Dr. Chen's dental牙科的 /ˈdɛntəl/ clinic诊所 /ˈklɪnɪk/. Receptionist接待员 /rɪˈsɛpʃənɪst/ Ava confirmed确认 /kənˈfərmd/ his appointment预约 /əˈpɔɪntmənt/, including allergies过敏 /ˈælərʤiz/, insurance保险 /ˌɪnˈʃʊrəns/, and any previous先前的 /ˈpriviəs/ reaction反应 /riˈækʃən/ to medicine药物 /ˈmɛdəsən/.
Dr. Chen inspected检查 /ˌɪnˈspɛktɪd/ his mouth口腔 /maʊθ/, then tested检测 /ˈtɛstɪd/ one molar磨牙 /ˈmoʊlər/ with cold. "Raise your hand the moment this hurts," she said. The initial初步的 /ˌɪˈnɪʃəl/ test and X-rayX光 /ˈɛksˌreɪ/ itself本身 /ˌɪtˈsɛlf/ did indicate a deep深的 /dip/ cavity蛀洞 /ˈkævəti/ close接近 /kloʊz/ to the nerve神经 /nərv/. Its root牙根 /rut/ and surrounding周围的 /sərˈaʊndɪŋ/ bone骨头 /boʊn/ remained healthy健康的 /ˈhɛlθi/, with no infection感染 /ˌɪnˈfɛkʃən/.
A dental diagram示意图 /ˈdaɪəˌgræm/ presented存在的 /pərˈzɛnəd/ the options方案 /ˈɔpʃənz/. A temporary临时的 /ˈtɛmpərˌɛri/ filling补牙材料 /ˈfɪlɪŋ/ might reduce discomfort不适 /dɪˈskəmfərt/ but need replacement替换品 /rɪˈpleɪsmənt/. A permanent永久的 /ˈpərmɑˌnɛnt/ one could remove去除 /riˈmuv/ decay龋坏 /dɪˈkeɪ/ and save保住 /seɪv/ the tooth牙齿 /tuθ/. Unless除非 /ənˈlɛs/ treated治疗 /ˈtritɪd/, inflammation炎症 /ˌɪnfləˈmeɪʃən/ might require a crown牙冠 /kraʊn/, root therapy疗法 /ˈθɛrəpi/, or major surgery手术 /ˈsərʤəri/. Jack asked about gas气体 /gæs/ or local anesthetic麻醉剂 /ˌænəsˈθɛtɪk/, recovery恢复 /rɪˈkəvəri/, additional额外的 /əˈdɪʃənəl/ danger危险 /ˈdeɪnʤər/, and the total总额 /ˈtoʊtəl/ estimate估价 /ˈɛstəˌmeɪt/ instead of silently默默地 /ˈsaɪləntli/ accepting her first suggestion建议 /səˈʤɛsʧən/.
They chose permanent treatment治疗 /ˈtritmənt/. Dentist牙医 /ˈdɛntɪst/ Chen reviewed检查 /rivˈjud/ the consent同意 /kənˈsɛnt/ form表格 /fɔrm/ while nurse护士 /nərs/ Rosa prepared准备了 /priˈpɛrd/ a sterile无菌的 /ˈstɛrəl/ tray托盘 /treɪ/, drill牙钻 /drɪl/, and protective防护的 /prəˈtɛktɪv/ glasses护目镜 /ˈglæsɪz/. The injection注射 /ˌɪnˈʤɛkʃən/ produced产生 /prəˈdust/ a brief短暂的 /brif/ reaction; soon很快 /sun/ Jack's cheek脸颊 /ʧik/ and tongue舌头 /təŋ/ felt numb麻木的 /nəm/. Dr. Chen isolated隔离了 /ˈaɪsəˌleɪtɪd/ the tooth, removed damaged损坏的 /ˈdæmɪʤd/ tissue组织 /ˈtɪʃu/, cleaned the surface表面 /ˈsərfəs/, and shaped塑形 /ʃeɪpt/ solid固体的 /ˈsɑləd/ material to match匹配 /mæʧ/ its natural自然的 /ˈnæʧərəl/ color颜色 /ˈkələr/. She paused暂停 /pɔzd/ when Jack raised举起了 /reɪzd/ a finger手指 /ˈfɪŋgər/, then polished抛光了 /ˈpɑlɪʃt/ the filling and tested his bite咬合 /baɪt/ force力度 /fɔrs/.
Before Jack left the chair牙椅 /ʧɛr/, Rosa entered the diagnosis诊断 /ˌdaɪəgˈnoʊsəs/, procedure操作 /prəˈsiʤər/, dosage剂量 /ˈdoʊsɪʤ/, and response反应 /rɪˈspɑns/ in his patient病人 /ˈpeɪʃənt/ chart表格 /ʧɑrt/. Numbness could affect影响 /əˈfɛkt/ speech说话能力 /spiʧ/ and taste味觉 /teɪst/. He should avoid heat热度 /hit/ until sensation感觉 /sɛnˈseɪʃən/ returned completely完全地 /kəmˈplitli/ and never test the area by biting his lip. Swelling肿胀 /sˈwɛlɪŋ/, fever发烧 /ˈfivər/, blood血液 /bləd/, or severe严重的 /səˈvɪr/ discomfort required必需的 /rikˈwaɪərd/ a phone电话 /foʊn/ call. Unless a physician医师 /fəˈzɪʃən/ gave different advice建议 /ədˈvaɪs/, he should take服用 /teɪk/ no pain疼痛 /peɪn/ tablet药片 /ˈtæblət/ or other drug beyond the stated amount剂量 /əˈmaʊnt/.
Ava compared the final bill账单 /bɪl/ with the estimate. Insurance covered涵盖 /ˈkəvərd/ the examination检查 /ɪgˌzæməˈneɪʃən/ and a fixed固定的 /fɪkst/ percentage比例 /pərˈsɛnɪʤ/ of treatment. She separated分开的 /ˈsɛpərˌeɪtɪd/ the clinic fee费用 /fi/ from Jack's payment付款 /ˈpeɪmənt/ and printed打印的 /ˈprɪnɪd/ an official正式的 /əˈfɪʃəl/ receipt收据 /rɪˈsit/. The service, coverage保险范围 /ˈkəvərɪʤ/, remaining剩余的 /rɪˈmeɪnɪŋ/ figure数值 /ˈfɪgjər/, and cancellation取消 /ˌkænsəˈleɪʃən/ terms条款 /tərmz/ appeared on one page; a follow-up随访 /ˈfɑloʊˌəp/ was included.
The clinic partnered合作 /ˈpɑːrtnərd/ with a college dental faculty牙科学院 /ˈfækəlti/ to study oral口腔的 /ˈɔrəl/ disease疾病 /dɪˈziz/ in the local population人群 /ˌpɑpjəˈleɪʃən/, including youth青少年 /juθ/ and adults成人 /ˈædəlts/ from various各种的 /ˈvɛriəs/ cultural文化的 /ˈkəlʧərəl/ groups. A professor教授 /prəˈfɛsər/ discussed findings研究结果 /ˈfaɪndɪŋz/ from one thousand千 /ˈθaʊzənd/ patients: sugar糖 /ˈʃʊgər/ and delayed延误 /dɪˈleɪd/ care increased增加了 /ˌɪnˈkrist/ danger, while early intervention干预 /ˌɪntərˈvɛnʃən/ produced a positive积极的 /ˈpɑzətɪv/ result. Patients themselves reported报告了 /ˌriˈpɔrtəd/ pain level, treatment type类型 /taɪp/, recovery length时长 /lɛŋθ/, and percentages; the anonymous匿名的 /əˈnɑnəməs/ database数据库 /ˈdætəˌbeɪs/ contained no names, gender性别 /ˈʤɛndər/, ethnic族裔的 /ˈɛθnɪk/ background背景 /ˈbækˌgraʊnd/, or private私人的 /ˈpraɪvət/ text文字 /tɛkst/. Jack permitted允许 /pərˈmɪtɪd/ Rosa to add his case as one example.
At follow-up, an additional lab实验室 /læb/ experiment试验 /ɪkˈspɛrəmənt/ showed tooth samples样本 /ˈsæmpəlz/ exposed暴露的 /ɪkˈspoʊzd/ to various drinks; particularly sugary ones caused color changes and bacterial细菌的 /bækˈtɪriəl/ growth生长 /groʊθ/. Bacteria细菌 /bækˈtɪriə/ were cells细胞 /sɛlz/ that tend往往 /tɛnd/ to grow, not a virus病毒 /ˈvaɪrəs/; pain signals信号 /ˈsɪgnəlz/ reached the brain大脑 /breɪn/. Jack could relate联系起来 /rɪˈleɪt/ his new knowledge知识 /ˈnɑlɪʤ/ to the familiar熟悉的 /fəˈmɪljər/ drill sound声音 /saʊnd/, despite traditional传统的 /trəˈdɪʃənəl/ fear恐惧 /fɪr/ spread传播 /sprɛd/ through films and social media. Treatment was successful成功的 /səkˈsɛsfəl/ because he had a chance to ask questions. Therefore因此 /ˈðɛrˌfɔr/, dental care offered hope without hiding dangerous危险的 /ˈdeɪnʤərəs/ outcomes结果 /ˈaʊtˌkəmz/. Perhaps its core核心的 /kɔr/ concept概念 /ˈkɑnsɛpt/ held one truth: combine结合 /ˈkɑmbaɪn/ science科学 /saɪəns/, teaching教学 /ˈtiʧɪŋ/, and communication沟通 /kəmˌjunəˈkeɪʃən/ to prevent预防 /prɪˈvɛnt/ suffering痛苦 /ˈsəfərɪŋ/ and protect society社会 /soʊˈsaɪɪti/.
