目的观察五倍子水提取物处理早期人工釉质龋后的表面形态。方法采用化学人工龋制备法,将釉质块随机分成六组,分别用1、10、30mg/mL五倍子溶液,380mL/L氟化氨银,20mL/L氟化钠以及去离子水处理,进行体外pH循环,扫描电镜观察釉质表面结构。结果经五倍子与氟化氨银处理后的釉质表面形成致密均匀、形状不规则的指状结构,长约0.08~0.6μm;氟化钠处理后釉质表面形成大小不一,散在的小球状结构,直径约0.02~2μm;去离子水处理的釉质表面成蜂巢状结构。结论1、10、30mg/mL五倍子溶液处理后釉质表面结构与氟化氨银组相似;1mg/mL可能是五倍子水提取物的有效浓度,但不一定是最低有效浓度;从表面形态上看,五倍子所生成的结构可能与抑制脱矿、促进再矿化有关。

AIM:: To investigate the effect of Chinese nutgall on experimental root caries remineralization. METHODS: The root caries with chemical demineralization model was prepared. The samples were treated with 30mg/ml Chinese nutgall, 20g/L NaF, 380g/L Ag(NH3)2F and deionized water respectively, then were soaked in the remineralization solution for 7d. The surface morphology, lesion depth and total volume of demineralization were observed through SEM and MRG. RESULTS: Before remineralization, through SEM, short blunt ecptoma was found on the surface of lesions of samples in Chinese nutgall group and Ag(NH3)2F group; while in NaF group, globular ecptoma was seen scattering on the surface of the lesions, together with lacune; in deionized group, there was Sharpey's fiber. After remineralization, the surface structure of samples in Chinese nutgall group and Ag(NH3)2F group became compacter and steadier, with presentation of small blotch and trabs; in NaF group, there was still lacune with trab- like structure on the surface of the samples; in deionized group, the surface of samples was honeycomb appearance. The analysis of each treatment through MRG showed that they had remarkable effect of enhancing remineralization on root caries, compared with deionized water (P<0.05). Among the treatments, Ag(NH_3)_2F showed the best effect, and there was no significant difference between Chinese nutgall group and NaF group.CONCLUSION: Chinese nutgall shows the effect of inhibiting the progress of experimental root caries and enhancing its remineralization .

目的:研究五倍子提取液促进实验性根面龋再矿化的作用。方法:采用化学法制备根面龋模型,用500g/L五倍子提取液,380g/L氟化氨银液,20g/L氟化钠液和去离子水处理后放入再矿化液中7d,用扫描电镜和显微放射成像术分别观测其表面形态、龋损深度和脱矿量。结果:再矿化前,扫描电镜观察五倍子与氟化氨银处理后牙骨质龋表面形成不规则短钝状突起;氟化钠液组形成大小不一的散在大球状突起,可见一些腔隙存在;去离子水组大量分布夏伯氏纤维。再矿化后,五倍子液和氟化氨银液组表面结构更加致密,均匀,呈小斑块,条索状;氟化钠液组表面也出现条索状结构,但仍有孔隙或腔隙存在;去离子水组表面出现蜂窝状结构。显微放射成像术分析各药物处理组均能明显促进实验性根面龋的再矿化,与去离子水相比相差显著(P<0.05),其中氟化氨银液组效果最好,五倍子液和氟化钠液相当。结论:五倍子具有抑制实验性根面龋进展,促进其再矿化的作用。

>=OBJECTIVE: Dental caries is fundamentally a microbial disease, which involves the hard tissue of tooth. The prevention of dental caries have been extensively studied worldwide, and there are many theories and prescribes in ancient Chinese natural medicine deal with dental caries, which facilitate the study of preventing dental caries by herbal medicine. It has been proved that some of the Chinese natural medicines can not only inhibit the growth and metabolism of cariogenic bacterial, but have favorable effect in the process of demineralization and remineralization of dental hard tissue. Traditional statistical assessment method can not evaluate the dual anticaries effect of Chinese traditional medicine properly, so this study focused on the multi-indexes comprehensive assessments applying to the evaluation of the anticaries effect of Chinese traditional medicine. METHODS: TOPSIS and Fuzzy Comprehensive Evaluation is applied in the comprehensive assessment for the evaluation of the anticaries effect of Chinese traditional medicines. The weights of assessment indexes were determined by the method of analytic hierarchy process. RESULTS: Appling the two methods to assessment, results are consistent, which showed that the assessment conclusions are credible. TOPSIS can expand the other's applying range. Among the two methods, Fuzzy Comprehensive Evaluation is the most subjective and acquires the lest information because index weighting is not needed. The results of the comprehensive assessment forecast the possibility of eleven tested Chinese traditional medicines in future utilizing of caries prevention. CONCLUSION: TOPSIS method and Fuzzy Comprehensive Evaluation are both good methods for comprehensive assessing anticaries effect of Chinese traditional medicines, but Fuzzy Comprehensive Evaluation is more impersonal than TOPSIS, and can exclude the influence of the out-of-line data as much as acquire more in formation. The example proved that applying these two methods in anticaries effect evaluation is successful. Both methods can be used to forecast the future utilizing for anticaries area.
