Comparative growth or inhibition of growth of human gingival fibroblasts on experimental root surfaces was used to assess the efficacy in vitro of the Cavitron and Prophy-Jet. Six teeth with a hopeless periodontal prognosis, slated for prosthetic replacement, were extracted and sectioned into 12 specimens. Experimental specimens were instrumented with the Cavitron or Cavitron and Prophy-Jet. Four calculus-covered control specimens were not treated. Eight root specimens in fibroblast tissue culture were stained with 1.0% toluidine blue for determination of fibroblast viability after 48 hours. No fibroblast growth took place on calculus control specimens. Cavitron specimens showed light fibroblast growth and viability. Cavitron/Prophy-Jet specimens showed superior growth and vitality of fibroblasts.
通过比较人牙龈成纤维细胞在实验性牙根表面的生长或生长抑制情况，来评估卡威创（Cavitron）和洁治喷砂机（Prophy-Jet）的体外功效。选取6颗牙周预后无望、计划进行修复性替代治疗的牙齿，将其拔除并切成12个标本。对实验标本使用卡威创或卡威创与洁治喷砂机进行处理。4个覆盖牙石的对照标本未作处理。将8个牙根标本置于成纤维细胞组织培养中，48小时后用1.0%的甲苯胺蓝染色以测定成纤维细胞的活力。在牙石对照标本上未出现成纤维细胞生长。卡威创标本显示有成纤维细胞轻度生长和活力。卡威创/洁治喷砂机标本显示有成纤维细胞的更好生长和活力。
