A data baseline on dental cutting methodologies was established by means of a survey of North American dental school teaching.
Sixty-four North American dental schools were surveyed regarding their recommendations on handpiece usage and coolant flow rates in fixed prosthodontics and operative dentistry.
High-speed handpieces were the instruments of choice for tooth preparation in fixed prosthodontics. In operative procedures, recommendations for sole use of the high-speed, the low-speed, or both handpiece types were more uniform.
North American dental schools advocate greater use of high-speed than low-speed handpieces. Although the use of high-speed handpieces predominate in schools in Canada and Puerto Rico, there is a proportionately higher use of low-speed handpieces than in US dental schools. Few (approximately 1 in 5) schools made recommendations on coolant flow rates during cutting procedures.
通过对北美牙科学院教学情况的调查，建立牙科切割方法的数据基线。
对64所北美牙科学院进行了调查，内容涉及它们在固定修复和牙体手术中对手持式器械使用及冷却液流速的建议。
高速手持器械是固定修复中牙齿预备的首选工具。在手术操作中，关于单独使用高速、低速或两种手持器械类型的建议更为统一。
北美牙科学院提倡更多地使用高速手持器械而非低速手持器械。尽管在加拿大和波多黎各的院校中高速手持器械的使用占主导地位，但与美国牙科学院相比，低速手持器械的使用比例相对较高。很少有院校（约五分之一）对切割过程中的冷却液流速提出建议。
