New classification system for complex root canal morphology first molars

This folder contains the  stereolithography (STL) files of micro-CT scans required to 3D print illustrative models for a new suggested classification system for complex root canal configurations. Each STL file represents a configuration type within a group. The system consists of 12 basic categories or groups (A-D) each with 3 types (1-3). The folder also contains the STL files for rare types of root and canal morphologies: a C-shaped root canal system found in a maxillary first molar and a radix entomolaris tooth found on a mandibular first molar.

本文件夹包含用于3D打印新型分类系统中复杂根管结构演示模型的微CT扫描的分层实体造型（STL）文件。每个STL文件代表一组中的某一配置类型。该系统由12个基本类别或分组（A-D）组成，每个分组包含3种类型（1-3）。此外，文件夹中还包含罕见根管和根管形态的STL文件：一种位于上颌第一磨牙的C形根管系统和一种位于下颌第一磨牙的根端齿。
