目的：本研究探讨了专业机械牙齿清洁（PMTC）糊剂对不同主题material.Methods表面纹理的影响：两个一步PMTC糊剂，Clinpro清洁糊剂PMTC（CP）和PRG亲护理凝胶（PG），和多步PMTC糊剂，Merssage常规（MR），Merssagge精细（MF），Merssage Plus（MP），被使用。为了比较，使用不含糊剂的蒸馏水（DW）进行PMTC。所用的受试材料是牛牙釉质（ENA）和牙本质（DEN）、树脂复合材料（FSU）和二硅酸锂（IEC）。使用#2000粒度的碳化硅纸抛光制备的试样。PMTC进行使用刷子在1，000 rpm的15 s。结果：表面粗糙度（Ra）值的标本前和后PMTC通过激光扫描显微镜测量。获得了受试材料的努普硬度值（KHN）。PMTC糊剂和受试材料的类型对Ra值和KHN有显著影响。对于大多数受试材料，PMTC后Ra值的降序为MR > MF > CP > PG > MP > DW。结论：一步PMTC糊剂虽然有效，但在PMTC过程中，重要的是要考虑主题材料。
Purpose: This study investigated the influence of professional mechanical tooth cleaning (PMTC) pastes on the surface texture of different subject materials.Methods: Two one-step PMTC pastes, Clinpro Cleaning Paste for PMTC (CP) and PRG Pro-Care Gel (PG), and multiple-step PMTC pastes, Merssage Regular (MR), Merssagge Fine (MF), and Merssage Plus (MP), were used. For comparison, PMTC was performed using distilled water without paste (DW). The subjected materials used were bovine enamel (ENA) and dentin (DEN), a resin composite (FSU), and lithium disilicate (IEC). The prepared specimens were polished using a #2000-grit silicon carbide paper. PMTC was performed using a brush at 1,000 rpm for 15 s.Results: The surface roughness (Ra) values of the specimens before and after PMTC were measured by laser scanning microscopy. The Knoop hardness number (KHN) of the subjected material was obtained. The types of PMTC pastes and subject materials had a significant influence on the Ra values and KHN. For the majority of subject materials, the descending order of Ra values after PMTC was MR > MF > CP > PG > MP > DW. The descending order of KHN of the materials was IEC > ENA > FSU > DEN.Conclusion: Although one-step PMTC pastes appeared to be effective, it is important to consider the subject material during PMTC.
