应用光学相干断层扫描技术，观察了含表面反应型预反应玻璃离子涂层材料(S-PRG)对18颗乳牙乳牙釉质脱矿的影响。拔除牙髓，用蒸馏水对每颗牙齿进行超声波清洗。用0.1M乳酸缓冲液处理6颗牙(De组)。第二组(n=6)，在脱矿前涂抹一层涂层材料(PRG组)。第三组(对照组，n=6)保留人工唾液。利用光学相干断层扫描技术，测量牙釉质表面预定位置的峰值信号强度(DB)和1/e2处的宽度(µm)，并计算积分值。所有数据采用方差分析和图基-克雷默检验(α=0.0 5)。虽然不同组间积分值的变化不同，但对照组有少量但显著的增加，而De组有少量但显著的下降。在PRG组，积分值在实验开始后第7天显著升高，此后显著增加。我们的发现表明，含有S-PRG填料的涂层材料可以防止乳牙釉质脱矿。
We used optical coherence tomography to examine the effect of a coating material containing surface reaction-type pre-reacted glass-ionomer (S-PRG) filler on primary enamel demineralization in 18 extracted human primary teeth. The pulp was removed, and each tooth was ultrasonically cleaned with distilled water. Six teeth were treated with 0.1-M lactic acid buffer solution (De group). In the second group (n = 6), a thin film of coating material was applied before demineralization (PRG group). A third group (Control group; n = 6) was maintained in artificial saliva. Using optical coherence tomography, we measured peak signal intensity (dB) and width at 1/e2 (µm) at predetermined locations on the enamel surface and calculated integrated values. All data were analyzed with ANOVA and the Tukey-Kramer test (α = 0.05). Although changes in integrated values differed between groups, there was a small but significant increase in the Control group and a small but significant decrease in the De group. In the PRG group, integrated values were significantly higher at 7 days after the start of the experiment and significantly increased thereafter. Our findings indicate that a coating material containing S-PRG fillers may prevent primary enamel demineralization.
