问题 咬诊法与染色法可用于帮助诊断以下哪种疾病
选项 A.隐裂牙 B.慢性牙髓炎 C.根尖周炎 D.死髓牙 E.髓石
答案 A
解析 :咬诊法检查牙隐裂:把小木签放置在疑有隐裂的部位,嘱患者咬,若有隐裂则产生咬合痛。染色法:2%碘酊或1%甲紫液涂布疑为隐裂处,用75%酒精擦干,隐裂纹处染色较深。

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
