本研究旨在确定Papacárie®与传统方法相比在微生物植物群、时间、组织去除量、儿童行为、疼痛感知和治疗偏好方面的有效性。随机选择4-9岁儿童乳磨牙30颗，分为两组，A组采用常规方法，B组采用Papacárie®方法。相比之下，两组的微生物生长、细菌总数和乳酸杆菌计数无统计学差异（P = 0.36）。A、B组的平均空洞入口直径分别为0.98133 mm和0.26083 mm（P < 0.001）。A组平均准备时间为4.7min，B组为17.96min，两组比较有显著性差异（P < 0.001）。A、B组治疗前后Frankl行为评分均以3分者居多，差异无统计学意义（P = 1）。在A组中，50%的儿童没有出现疼痛，而在B组中为86.7%（P = 0.01）。两组治疗偏好差异无统计学意义（P = 0.12）。因此，化学机械去龋方法可以被认为是一种有效的方法，以控制疼痛和保存良好的牙齿结构，在龋洞挖掘。
This study was aimed to determine the effectiveness of Papacárie® for caries removal as compared to the conventional method with respect to microbial flora, time, the amount of tissue removal, child's behavior, pain perception, and preference of treatment. Sixty primary molars of 30 children of age 4-9 years were selected randomly and divided into two groups of 30 teeth each: Group A treated by conventional method and group B with Papacárie® method. Comparatively, no statistical difference was seen in microbial growth, total bacterial count, and lactobacilli count in both the groups (P = 0.36). The mean cavity entrance size with group A was 0.98133 mm and group B was 0.26083 mm (P < 0.001). The mean preparation time for group A was 4.7 Mins (minutes) and group B was 17.96 min s (P < 0.001). Majority of kids of both group A and B scored 3 (Frankl Behavior Rating Scale) before and after the treatment showing no statistical difference in their behavioral score (P = 1). In group A 50% of children experienced no pain as compared to 86.7% in group B (P = 0.01). There was no statistical difference in the preference of treatment (P = 0.12). Thus, the Chemo mechanical caries removal method can be considered as an effective method to control pain and preserve sound tooth structure during caries excavation.
