Indirect pulp capping is the main treatment modality for reversible pulpitis.
To evaluate the efficacy of Biodentine® and Calcium hydroxide in the formation of dentin bridge.
A double blinded, randomized clinical control trial involving 50 consenting subjects, aged 16 to 55 years with deep carious vital teeth. It was a comparative study with intervention comparing Biodentine® (test) and Calcium hydroxide (control). Subjects' teeth were assessed for normal response to pulp testing. Cavity preparation was done and the cavity was dressed with either Biodentine® or Calcium hydroxide (Ca(OH)2) then restored with Glass ionomer cement. A bitewing digital dental x-ray was taken at the end of the procedure to measure radiographically the dentin depth as base line using a digital meter. The subjects' teeth were examined radiographically at three, six and nine months. The probability level of p<0.05 was considered significant.
There was a progressive increase in dentin formation at three months, six months and a significant increase at nine months: the subjects' teeth in the Biodentine® group recorded an increase in dentin depth of mean 0.67±0.07mm in the mesial aspect and mean 0.66±0.07mm in both the middle and distal aspects. The Ca(OH)2 group recorded an increase in dentin depth of mean 0.55±0.07mm in the mesial aspect, mean 0.52±0.07mm in the middle aspect and mean 0.55±0.07mm in the distal aspect at nine months. (p value 0.001).
Biodentine® and Ca(OH)2 have proven to be efficacious in dentin bridge formation. The Biodentine® group showed a statistically significant increase in mean dentin depth relative to that of Ca(OH)2 group following indirect pulp capping of deeply carious teeth.
间接盖髓术是治疗可复性牙髓炎的主要治疗方式。
评估 Biodentine® 和氢氧化钙在牙本质桥形成中的疗效。
一项双盲、随机临床对照试验，纳入了 50 名年龄在 16 至 55 岁之间、有深龋活髓牙且同意参与的受试者。这是一项干预性比较研究，比较 Biodentine®（试验组）和氢氧化钙（对照组）。对受试者的牙齿进行牙髓测试以评估其正常反应。进行窝洞预备，窝洞分别用 Biodentine® 或氢氧化钙（Ca(OH)2）覆盖，然后用玻璃离子水门汀修复。在操作结束时拍摄咬合翼片数字化牙科 X 光片，使用数字测量仪在影像学上测量牙本质深度作为基线。在三个月、六个月和九个月时对受试者的牙齿进行影像学检查。p<0.05 的概率水平被认为具有统计学意义。
在三个月、六个月时牙本质形成逐渐增加，在九个月时显著增加：Biodentine® 组受试者牙齿的近中面牙本质深度平均增加 0.67±0.07mm，中间面和远中面平均增加 0.66±0.07mm。在九个月时，Ca(OH)2 组近中面牙本质深度平均增加 0.55±0.07mm，中间面平均增加 0.52±0.07mm，远中面平均增加 0.55±0.07mm。（p 值 0.001）。
Biodentine® 和 Ca(OH)2 已被证明在牙本质桥形成中有效。在对深龋牙齿进行间接盖髓术后，Biodentine® 组相对于 Ca(OH)2 组在平均牙本质深度上有统计学意义的显著增加。
