问题
选项
答案 A
解析 银汞与牙体组织无粘结性,因此如果牙尖折裂发生,一边的牙尖会折断。但是树脂与牙体组织有较强的粘结性,所以牙尖发生折裂时会把更多的牙体组织一起损伤,缺损会更大,折裂面到龈下的几率也会更高,因而更不利于修复。

  • 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.
