The purpose of this study was to compare the chemomechanical caries-removal system (Carisolv) with high-speed excavation in cavitated occlusal caries of primary molars. Design and setting. The study was a randomized controlled, clinical trial in which the two techniques were compared in each subject. Participants were chosen from public schools, in Maracaibo County, Zulia State, Venezuela.
The sample consisted of 80 primary molars selected from 40 children (mean age 7.7+/-0.7 years). Each patient had at least two contralateral primary molars with cavitated occlusal caries and approximately equal-size access to lesions. The outcome variables were: clinically complete caries removal, size of the opening of the cavity, volume of carious tissue removed, pain during caries removal, anaesthesia requested by the patient, caries-removal time, and behaviour and preference of patients.
All treated molars were clinically caries free whichever caries-removal procedure was used. When Carisolv' was used the final cavity entrance sizes were smaller (P<0.001) and the estimated volume of tissue removed was less (P<0.001). The time taken for caries removal was three times longer (7.51+/-1.83 min, P<0.001). Some pain was reported by seven (17.5%) participants when Carisolv was used, compared with 16 (40%) when high-speed excavation was used (P<0.05). Using the Carisolv method there was a higher proportion of patients with positive behaviour (P<0.01), and 71.0% (P<0.05) preferred this treatment.
Carisolv is an effective clinical alternative treatment for the removal of occlusal dentinal caries in cavitated primary molars; it is more conservative of dental tissue and appeared to be more comfortable for most patients, although the clinical time spent is longer than when using high-speed excavation.
本研究旨在比较化学机械去龋系统（Carisolv）与高速开髓去龋法治疗乳磨牙牙合面龋洞的效果。设计与研究地点。本研究为随机对照临床试验，对每位受试者的两种技术进行比较。研究对象选自委内瑞拉苏利亚州马拉开波县的公立学校。
样本包括从40名儿童（平均年龄7.7±0.7岁）中选取的80颗乳磨牙。每位患者至少有两颗对侧牙合面龋洞的乳磨牙，且龋损大小相近。观察指标包括：临床上去净龋坏组织、龋洞开口大小、去除龋坏组织的体积、去龋过程中的疼痛、患者要求的麻醉、去龋时间以及患者的行为和偏好。
无论采用哪种去龋方法，所有治疗的磨牙临床检查均无龋坏。使用Carisolv时，最终龋洞入口尺寸更小（P<0.001），去除组织的估计体积更少（P<0.001）。去龋时间长三倍（7.51±1.83分钟，P<0.001）。使用Carisolv时，7名（17.5%）受试者报告有一些疼痛，而使用高速开髓去龋法时有16名（40%）（P<0.05）。采用Carisolv方法时，表现积极的患者比例更高（P<0.01），71.0%（P<0.05）的患者更喜欢这种治疗方法。
Carisolv是治疗乳磨牙牙合面龋洞型牙本质龋的一种有效的临床替代方法；它对牙体组织的损伤更小，对大多数患者来说似乎更舒适，尽管临床操作时间比使用高速开髓去龋法更长。
