【摘要】：目的探討激光熒光齲齒診斷儀用于牙科充填物下齲損檢查的可行性和影響因素。方法應用激光熒光齲齒診斷儀測量各種材料(1種窩溝封閉劑、6種樹脂和1種銀汞)1mm厚時的自身熒光值,然后測量熒光值為99的齲損組織位于0~1mm封閉劑和樹脂下、1mm和2mm銀汞下時的熒光值。結果材料自身熒光值均小于齲齒診斷界值13。齲損位銀汞下時,測量值接近0。齲損位封閉劑和樹脂下時,測量值減少,減少量分別為64.3±29.6和73.7±21.6,測量值與材料厚度呈負相關(P=0.000),診斷一能檢查到齲損的封閉劑和樹脂厚度分別為(0.384±0.250)mm和(0.340±0.203)mm。結論該診斷儀不能用于銀汞下齲損的檢查,可用于極薄的封閉劑和樹脂下齲損的檢查。
[Abstract]:Objective to investigate the feasibility and influencing factors of laser fluorescence dental caries diagnostic instrument for dental subcaries. Methods the self fluorescence values of 6 kinds of resin and 1 kind of silver mercury were measured by laser fluorescence dental caries diagnostic instrument. Then the fluorescence values of the caries with a fluorescence value of 99 were measured at 1 mm under 0~1mm sealant and 1 mm under resin and under 2mm silver mercury. Results the self-fluorescence values of the materials were lower than the diagnostic threshold of dental caries. The measured value is close to 0. 0. The measured values were decreased by 64.3 鹵29.6 and 73.7 鹵21.6, respectively. There was a negative correlation between the measured values and the thickness of the material. The thickness of the sealant and resin that could detect the caries was 0.384 鹵0.250)mm and 0.340 鹵0.203 mm. respectively. Conclusion the instrument can not be used for the detection of subcaries of silver mercury, but also for the detection of extremely thin sealants and resin caries.
