Abstract

Purpose: This study investigated the magnitude, direction, and temporal aspects of the force applied during instrumentation with a piezoelectric ultrasonic periodontal scaler, compared this force with recommendations in the literature, and assessed the influence of the profession (dentist or dental hygienist) and calculus hardness.

Materials and methods: The force applied by ten dental hygienists and six dentists during debridement of comparatively soft and hard artificial dental calculus with a piezoelectric ultrasonic scaler was recorded in-vitro. The total force and its components in three axes were statistically analysed.

Results: During debridement of soft artificial dental calculus, the mean total force applied by dental hygienists was 0.34 N (± 0.18 N, range: 0.13 N to 0.59 N) and by dentists 0.28 N (± 0.33 N, range: 0.06 N to 0.95 N), and the total force exceeded 0.5 N approximately 23% and 14% of the time for dental hygienists and dentists, respectively. During debridement of hard artificial dental calculus, the mean total force applied by dental hygienists was 0.63 N (± 0.40 N, range: 0.28 N to 1.64 N) and by dentists 0.57 N (± 0.17 N, range: 0.34 N to 0.76 N); the total force exceeded 0.5 N more than half of the time for both professions. On average, dental hygienists applied 1.85x (p = 0.04) and dentists 2.04x (p = 0.06) higher force on hard than on soft artificial calculus. However, dental hygienists and dentists used similar forces during the debridement of both hard (p = 1.00) and soft (p = 0.26) calculus.

Conclusion: The force applied during the debridement of hard artificial dental calculus was statistically significantly higher than during the debridement of soft artificial dental calculus. No statistically significant difference between dentists and dental hygienists was found. The force applied by both groups on soft and hard artificial dental calculus frequently exceeded recommended values.

使用压电超声牙周洁治器对清创过程中的力进行体外测量。

目的：本研究调查了使用压电式超声波牙周洁治器进行器械治疗时所施加的力的大小、方向和时间方面，将该力与文献中的建议进行了比较，并评估了职业（牙医或牙科卫生员）和牙结石硬度的影响：对 10 名牙科卫生员和 6 名牙医在使用压电超声波洁牙器清除相对较软和较硬的人工牙结石时施加的力进行了体外记录。结果：结果：在清除软人工牙结石时，牙科卫生员施加的平均总力为 0.34 N（± 0.18 N，范围：0.13 N 至 0.59 N），牙科医生为 0.28 N（± 0.33 N，范围：0.06 N 至 0.95 N），牙科卫生员和牙科医生施加的总力超过 0.5 N 的时间分别约占 23% 和 14%。在清除坚硬的人工牙结石时，牙科卫生员施加的平均总作用力为 0.63 N（± 0.40 N，范围：0.28 N 至 1.64 N），牙科医生为 0.57 N（± 0.17 N，范围：0.34 N 至 0.76 N）；两种职业的总作用力均有一半以上的时间超过 0.5 N。平均而言，牙科卫生员对硬质人工牙结石的作用力是软质人工牙结石的 1.85 倍（p = 0.04），牙科医生的作用力是硬质人工牙结石的 2.04 倍（p = 0.06）。然而，牙科卫生员和牙科医生在清除硬质（p = 1.00）和软质（p = 0.26）牙结石时使用的力量相似：结论：从统计学角度看，清除硬人工牙结石时使用的力量明显高于清除软人工牙结石时使用的力量。牙科医生和牙科卫生员之间的差异没有统计学意义。两组人员在软性和硬性人工牙结石上使用的力量经常超过推荐值。
