Abstract

Purpose: To investigate the mineral density and lesion depth of artificial caries lesions on aprismatic enamel and prismatic enamel created by lactic acid and acetic acid buffers.

Methods: Forty bovine enamel blocks were allocated to: aprismatic enamel (Group A) and prismatic enamel (Group C) in acetic acid buffer for 192 h and aprismatic enamel (Group B) and prismatic enamel (Group D) in lactic acid buffer for 96 h. The mineral loss and lesion depth were measured using micro-computed tomography.

Results: A significant difference (P = 0.01) was observed in the mineral loss (%) in the lesions on aprismatic enamel and prismatic enamel treated with lactic acid buffer while no significant difference (P = 0.51) was observed in the mineral loss (%) in the lesions on aprismatic enamel and prismatic enamel treated with acetic acid buffer. No significant difference was noted in the mean lesion depth of lesions on aprismatic enamel and prismatic enamel treated with acetic acid and lactic acid buffers (P > 0.05).

Conclusion: Aprismatic enamel and prismatic enamel have similar mineral loss in acetic acid while prismatic enamel showed more mineral loss compared to aprismatic enamel in lactic acid.

两种化学模型对柱状牙釉质和柱状牙釉质表面下龋形成的比较研究。

目的:探讨乳酸和乙酸缓冲液对柱状牙釉质和柱状牙釉质人工龋的影响。方法:将40块牛牙釉质块分为:乙酸缓冲液中棱柱状牙釉质(A组)和棱柱状牙釉质(C组)放置192 h，乳酸缓冲液中棱柱状牙釉质(B组)和棱柱状牙釉质(D组)放置96 h。采用显微计算机断层扫描测量矿物质损失和损伤深度。结果:乳酸缓冲液处理的棱柱状牙釉质与棱柱状牙釉质病变处的矿物质损失(%)差异有统计学意义(P = 0.01)，醋酸缓冲液处理的棱柱状牙釉质与棱柱状牙釉质病变处的矿物质损失(%)差异无统计学意义(P = 0.51)。乙酸与乳酸缓冲液处理后柱状牙釉质的平均病变深度差异无统计学意义(P > 0.05)。结论:柱状牙釉质和棱柱状牙釉质在乙酸中有相似的矿物质损失，而在乳酸中棱柱状牙釉质的矿物质损失大于柱状牙釉质。
