Objective This study aimed to assess the validity of DIAGNOdent as a diagnostic device for the detection of secondary dental caries underneath different types of restorations. Methods A total of 60 extracted human permanent molars were used in this experimental study (30 sound teeth and 30 teeth with proximal caries); 20 teeth (10 sound and 10 carious) were randomly allocated into one of three restoration groups: composite, amalgam, or resin-modified glass ionomer (RMGI). All teeth were examined using both KaVo DIAGNOdent Classic and digital radiographic sensors. Results In the composite-restored teeth, DIAGNOdent showed excellent sensitivity (90%) and specificity (90%). On the other hand, digital radiography had high sensitivity (80%) and poor specificity (20%). In amalgam-restored teeth, DIAGNOdent showed low sensitivity (30%) and excellent specificity (100%), while radiographs showed good sensitivity (70%) and low specificity (30%). In the RMGI-restored teeth, DIAGNOdent had excellent sensitivity (100%) and 70% specificity, while digital radiography had poor sensitivity (30%) and excellent specificity (90%). Conclusions DIAGNOdent showed superior results in detecting secondary caries lesions underneath composite and RMGI restorations when compared to digital radiography. On the other hand, radiography emerged as a preferable method for the detection of secondary caries underneath amalgam restorations. Based on our findings, DIAGNOdent can be used in dental clinics for the early diagnosis of hidden secondary caries underneath composite and RMGI restorations.
目的 本研究旨在评估DIAGNOdent作为检测不同类型修复体下方继发龋诊断设备的有效性。方法 本实验研究共使用60颗拔除的人类恒牙（30颗健康牙和30颗邻面龋牙）；20颗牙（10颗健康牙和10颗龋牙）被随机分配到三个修复组之一：复合树脂、银汞合金或树脂改性玻璃离子（RMGI）。所有牙齿均使用卡瓦DIAGNOdent Classic和数字放射传感器进行检查。结果 在复合树脂修复的牙齿中，DIAGNOdent显示出优异的敏感性（90%）和特异性（90%）。另一方面，数字放射成像具有高敏感性（80%）和低特异性（20%）。在银汞合金修复的牙齿中，DIAGNOdent显示出低敏感性（30%）和优异的特异性（100%），而X线片显示出良好的敏感性（70%）和低特异性（30%）。在RMGI修复的牙齿中，DIAGNOdent具有优异的敏感性（100%）和70%的特异性，而数字放射成像具有低敏感性（30%）和优异的特异性（90%）。结论 与数字放射成像相比，DIAGNOdent在检测复合树脂和RMGI修复体下方的继发龋病变方面显示出更好的结果。另一方面，放射成像成为检测银汞合金修复体下方继发龋的首选方法。基于我们的研究结果，DIAGNOdent可用于牙科诊所早期诊断复合树脂和RMGI修复体下方隐藏的继发龋。
