The patient was a 32-year-old man who underwent amalgam restoration of the mandibular right second molar. An amalgam restoration fracture was diagnosed by intraoral optical coherence tomography (OCT), and pulp exposure was examined during cavity preparation. Subsequently, a definitive ceramic restoration was fabricated, and the marginal fit in the oral cavity was evaluated using the OCT system.
The existing OCT system cannot acquire images inside the oral cavity because of the large probe size. However, the proposed intraoral OCT system can access the prostheses in the mandibular right second molar. Therefore, dental diagnosis for restoration treatment with dental prosthesis fracture, marginal gap, and pulp exposure after tooth preparation is possible using the proposed intraoral OCT system.
The use of the intraoral OCT system improved dental diagnosis by allowing the dentist to confirm quantitative values through cross-sectional images, rather than that by determining a treatment plan after visual dental diagnosis.
一名 32 岁男性，曾接受下颌右侧第二磨牙的银汞合金修复。通过口腔内光学相干断层扫描（OCT）诊断出银汞合金修复体破裂，并在窝洞制备过程中检查了牙髓暴露情况。随后，制作了明确的陶瓷修复体，并使用 OCT 系统评估口腔内的边缘拟合情况。
由于探头尺寸较大，现有的 OCT 系统无法获取口腔内的图像。然而，所提出的口腔内 OCT 系统可以进入下颌右侧第二磨牙的修复体。因此，使用所提出的口腔内 OCT 系统可以对修复体骨折、边缘间隙和牙预备后牙髓暴露等修复治疗进行牙科诊断。
口腔内 OCT 系统的使用通过横截面图像使牙医能够确认定量值，从而改善了牙科诊断，而不是通过视觉牙科诊断确定治疗计划。
