The aim of this study was to compare the clinical and radiographic outcomes of partial and complete caries removal (CCR) in permanent teeth with deep carious lesions.
One hundred and forty-three patients of age group 14-54 years with mature permanent molars having deep carious lesions were divided into two groups: partial caries removal (PCR) and CCR. A layer of soft, wet carious dentin was left adjacent to pulpal wall in PCR group, whereas in CCR group, complete infected caries was removed with the help of caries-detector dye. Teeth were restored with composite resin (Tetric N-Ceram; Ivoclar Vivadent), with base of resin-modified glass ionomer cement (RMGIC) and patients were recalled at 1, 3, 6, 12, and 18 months. Success was defined as absence of signs and symptoms of irreversible pulpitis (spontaneous pain, fistula, and swelling) and absence of periapical alterations (radiolucency at furcal or periapical region).
Pulp exposure occurred in 13 (9.55%) cases of CCR group. Statistical significant difference ( = 0.001) in terms of pulp exposure was found between two groups. After 18 months, 123 teeth were evaluated (CCR = 56 and PCR = 67) and the success rate in CCR group (98.21%) and the PCR group (92.53%) did not differ significantly ( = 0.115).
PCR could be as an elective treatment option for the mature permanent teeth with deep carious lesions.
本研究旨在比较恒牙深龋病变时部分龋去除与完全龋去除（CCR）的临床和影像学结果。
143例年龄在14 - 54岁、患有成熟恒牙深龋病变的患者被分为两组：部分龋去除（PCR）组和CCR组。PCR组在牙髓壁附近保留一层柔软、湿润的龋坏牙本质，而CCR组借助龋病检测染料去除所有感染龋坏组织。牙齿用复合树脂（Tetric N-Ceram；义获嘉伟瓦登特公司）修复，使用树脂改性玻璃离子水门汀（RMGIC）垫底，并在1、3、6、12和18个月时对患者进行复查。成功的定义为无不可逆性牙髓炎的体征和症状（自发痛、瘘管和肿胀）以及无根尖周改变（根分叉或根尖区的透射影）。
CCR组有13例（9.55%）发生牙髓暴露。两组在牙髓暴露方面存在统计学显著差异（= 0.001）。18个月后，评估了123颗牙齿（CCR组 = 56颗，PCR组 = 67颗），CCR组的成功率（98.21%）和PCR组的成功率（92.53%）无显著差异（= 0.115）。
对于患有深龋病变的成熟恒牙，PCR可作为一种选择性治疗方案。
