碳酸氢钠和氟化钠混合液治疗牙本质过敏症的临床研究

目的：观察碳酸氢钠和氟化钠混合液治疗牙本质症过敏的疗效。方法：实验组使用1mol/L浓度的碳酸氢钠和0．12mol/L浓度的氟化钠混合液；对照组用0．48mol/L浓度的氟化钠溶液，记录第3次治疗后的疗效及实验组3个月后的随访结果。结果：实验组，显效54例（90．00％），有效4例（6．67％），无效2例（3．33％），总有效58例（96．67％）。对照组，显效24例（40．00％），有效33例（55．00％），无效3例（5．00％），总有效57例（95．00％）。两组总有效率无显著差异（P＞0．05），显效率有显著差异（P＜0．05）。3个月后实验组疗效；显效47例（88．68％），有效4例（7．55％），无效2例（3．77％），总有效51例（96．23％）。结论：1mol/L浓度的碳酸氢钠和0．12mol/L浓度的氟化钠混合液是一种高效、作用持久、使用安全的牙本质脱敏剂。

Clinical study of treatment of dentine hypersensitivity with mixture of NaHCO3 and NaF solution

AIM: To observe the clinical effects of treatment of dentine hypersensitivity with mixture of 1mol/L NaHCO 3 and 0.12mol/L NaF solution. METHODS: The experimental group was treated with mixture of 1mol/L NaHCO 3 and 0.12mol/L NaF solution. The contrast group is 0.48mol/L NaF solution. The effects after the third treatment and follow up effects of the experimental group after three months were recorded respectively. RESULTS: The effects of the experimental group were obvious in 54 cases (90.00%), effective in 4 cases (6.67%), non in 2 case (3.33%), total effective in 58 cases (96.67%). The effects of the contrast group were obvious in 24 cases (40.00%), effective in 33 cases (55.00%), non in 3 cases (5.00%), total effective in 57 cases (95.00%). There is no significant difference between these two groups (P>0.05). There is significant difference between two groups for obviouse effective (P<0.05). Follow-up effects of the experimental group after three months were obviouse in 47 cases (88.68%), effective in 4 cases (7.55%), non in 2 cases (3.77%), total effective in 51 cases (96.23%). CONCLUSION: Mixture of 1mol/L NaHCO 3 and 0.12mol/L NaF solution is a kind of persistent, strong-effective, and safe agent for treatment of dentine hypersensitivity.
