研究目的: |
龋病,作为全球范围内危害口腔健康的第一大疾病。在临床上,二类洞口内直接充填需要借助口腔邻面成型系统的帮助,才能获得良好的充填效果。然而,发生在第二磨牙远中游离端的二类洞龋坏,常因第三磨牙的缺失或邻接异常,成型系统难以或者无法获得良好的就位,导致充填效果不佳。本研究拟比较目前临床上常用的口腔邻面成型系统在修复第二磨牙远中游离端二类洞的成型效果,为临床医生在实际操作中的成型系统选择提供一定帮助。 |

Objectives of Study: |
Dental caries, recognized as the most prevalent disease threatening global oral health, poses significant clinical challenges. For Class II cavity restorations, achieving optimal filling outcomes relies heavily on the use of proximal matrix systems. However, when caries occurs in the distal free-end of the second molar (often due to the absence or malpositioning of the third molar), conventional matrix systems frequently fail to achieve proper placement, leading to suboptimal restoration quality. This study aims to compare the performance of commonly used proximal matrix systems in restoring Class II cavities in the distal free-end of second molars, providing clinicians with evidence-based guidance for selecting the most effective system in such challenging cases. |

随机方法(请说明由何人用什么方法产生随机序列): |
由不参与研究的临床医生制备编号信封,内装分配方案(Matirx in a matrix/ Iovry Matirx)。术时,由临床操作者随机抽取,并拆封确定所用的成型系统。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
The allocation sequence (Matrix-in-a-matrix or Ivory Matrix) was prepared in sealed, numbered envelopes by a clinician not involved in the study. During the procedure, the operating clinician randomly selected and opened an envelope to determine the matrix system to be used. |
