The aim of this study was to evaluate the influence of erbium:yttrium-aluminum-garnet (Er:YAG) laser compared with traditional treatment on dentin permeability to calcitonin and sodium alendronate. Forty bovine roots were sectioned and divided into eight groups. Groups 1 and 2 (G1/G2) were immersed in saline solution; G1T/G2T were immersed in ethylene diamine tetra-acetic acid plus sodium lauryl ether sulfate (EDTA-T) and sodium hypochlorite (NaOCl); G1I/G2I were irradiated with Er:YAG laser (2.94 microm, 6 Hz, 40.4 J/cm(2)); G1TI/G2TI were immersed in EDTA-T, NaOCl and subjected to Er:YAG irradiation. After 4 h the radioactivity of the saline solution was measured. Statistical analysis revealed a significant difference (P < 0.05) when the groups treated with EDTA-T and NaOCl followed by Er:YAG laser irradiation were compared with the groups treated with EDTA-T only and with the groups that received no treatment. Er:YAG laser associated with traditional procedures significantly increased the diffusion of calcitonin and sodium alendronate through dentin. All groups showed calcitonin and sodium alendronate diffusion.

本研究的目的是评估The: 钇铝石榴石 (Er:YAG) 激光与传统治疗相比对牙本质对降钙素和阿仑膦酸钠渗透性的影响。将40个牛根切成八组。第1组和第2组 (G1/G2) 浸入盐溶液中; G1T/G2T浸入乙二胺四乙酸加月桂基醚硫酸钠 (edta-t) 和次氯酸钠 (NaOCl) 中; G1I/G2I用Er:YAG激光 (2.94微米,6Hz,40.4 J/cm(2)); 将G1TI/G2TI浸入edta-t、NaOCl中并进行Er:YAG照射。4小时后,测量盐溶液的放射性。统计学分析显示,当用edta-t和NaOCl治疗的组随后进行Er:YAG激光照射时,与仅用edta-t治疗的组和未接受治疗的组进行比较时,存在显着差异 (P <0.05)。Er: 与传统手术相关的YAG激光显着增加了降钙素和阿仑膦酸钠通过牙本质的扩散。所有组均显示降钙素和阿仑膦酸钠扩散。
