摘要目的探讨应用即刻暂时冠治疗隐裂牙的效果。方法选取2011年7月～2014年7月期间到我科就诊的因牙隐裂导致的急性牙髓炎、急慢性根尖周炎患者218例作为研究对象，其中有急性牙龈炎病牙数102颗，急性根尖周炎病牙数109颗，慢性瘘型根尖周炎病牙数122颗。按照就诊顺序将其随机分为实验组和对照组。将其进行再分组，其中急性牙髓炎实验组为A组，急性牙髓炎对照组为B组，急性根尖周炎实验组为C组，急性根尖周炎对照组为D组，慢性瘘型根尖周炎实验组为E组，慢性瘘型根尖周炎对照组为F组。比较不同疾病类型患者的治疗效果。结果在全冠修复前，实验组与对照组的治疗有效率差异无统计学意义（P＞0.05），在随访6、12个月时，实验组患者的治疗有效率均明显高于对照组，差异有统计学意义（P＜0.01）；在全冠修复前及随访6、12个月时，A组与C组比较，差异无统计学意义（x2=0.105、0.333、0.017，P＞0.05）；在全冠修复前及随访6、12个月时，A组与E组比较，差异有统计学意义（x2=7.667、6.769、5.939，P＜0.05），C组与E组比较，差异有统计学意义（x2=6.333、4.415、4.465，P＜0.05）；在全冠修复前及随访6、12个月时，B组与D组比较，差异无统计学意义（x2=5.125、5.375、2.980，P＞0.05）；在全冠修复前及随访6、12个月时，F组与D组比较，差异有统计学意义（x2=5.030、3.575、14.546，P＜0.05），F组与B组比较，差异有统计学意义（x2=11.315、23.793、18.285，P＜0.05）。结论使用即刻临时冠治疗隐裂牙，具有较高的治疗效果；隐裂导致的根尖周炎特别是瘘型根尖周炎患牙的远期疗效不佳。

Abstract：Objective To exp1ore the effect of app1ying immediate temporary crown to treat cracked teeth. Methods From Ju1y 2011 to Ju1y 2014,218 patients with acute pu1pitis and acute or chronic periapica1 periodontitis due to teeth cracked who visited our department for treatment were se1ected.There were 102 teeth in acute pu1pitis,109 in acute periapica1 periodontitis,and 122 in periapica1 periodontitis （fistu1a type).According to the sequence of seeing doctors,they were random1y divided into experimenta1 group and contro1 group.They were a1together divided into A to F groups inc1uding experimenta1 group of acute pu1pitis （group A),contro1 group of acute pu1pitis （group B),experimenta1 group of acute periapica1 periodontitis （group C),contro1 group of acute periapica1 periodontitis （group D),experimenta1 group of chronic-fistu1a periapica1 periodontitis （group E),and contro1 group of chronic-fistu1a periapica1 periodontitis （group F). The therapeutic effects in different types of denta1 diseases in the experimenta1 group and contro1 group were compared. Results Before comp1ete corona1 restoration,the therapeutic effect in the experimenta1 group and contro1 group was not statistica1 （P＞0.05).During 6-month and 12-month fo11ow up visits,the therapeutic effective rates in the experimenta1 group were much higher than those in the contro1 group with statistica1 difference （P＜0.01).There was no statistica1 difference in prior restoration of comp1ete crown,6-month fo11ow up visit,and 12 month fo11ow up visit between group A and group C （x2=0.105,0.333,0.017,P＞0.05).In comparison with group A and E,there were statistica1 differences in three above mentioned periods （x2=7.667,6.769,5.939,P＜0.05).There were statistica1 differences in three above mentioned periods between group C and group E （x2=6.333,4.415,4.465,P＜0.05).During three periods of prior restoration of comp1ete crown,6-month fo11ow up visit,and 12 month fo11ow up visit,there was no statistica1 difference between group B and group D （x2=5.125,5.375,2.980,P＞0.05).However, there were statistica1 differences between group F andgroup D （x2=5.030,3.575,14.546,P＜0.05) and between group F and group B （x2=11.315,23.793,18.285,P＜0.05). Conclusion In the treatment of cracked teeth,app1ication of immediate temporary crown can obtain a good therapeutic effect, but is not satisfactory for periapica1 periodontitis especia11y chronic-fistu1a periapica1 periodontitis in 1ong term.
