This series of case reports evaluated the impact of adhesive crown-root fragment reattachment in periodontally healthy teeth suffering from crown-root fractures on various parameters of periodontal health over a time course of 2 years.
A total of 20 teeth with crown-root fractures in 18 periodontally healthy subjects were evaluated. After open-flap access, crown-root fragments were adhesively reattached to the root stub. In all cases, the vertical difference between the alveolar bone crest and the fracture line was <or=1 mm, i.e. violating the biological width. Subsequently, clinical attachment level (CAL), probing pocket depth (PPD), bleeding on probing (BoP) and gingival index (GI) scores were recorded at 6, 12 and 24 months postoperatively for the restored teeth as well as plaque index (PlI) and periodontal screening index (PSI) values for the whole dentition.
Two years after therapy, recorded CAL, PPD, BoP, GI, PlI and PSI scores revealed healthy periodontal conditions in 18 out of 20 treated teeth. Two teeth had suffered again from fragment fracture due to new traumata.
Adhesive fragment reattachment in periodontally healthy teeth affected by crown-root fractures had no detrimental impact on periodontal health over a time course of 2 years.
本系列病例报告评估了在2年的时间跨度内,粘结冠根折裂片再附着对牙周健康的牙齿发生冠根折裂后牙周健康各项参数的影响。
对18名牙周健康受试者的20颗冠根折裂牙进行评估。翻瓣暴露后,将冠根折裂片粘结再附着于牙根残端。所有病例中,牙槽嵴顶与骨折线之间的垂直距离≤1mm,即破坏了生物学宽度。随后,在术后6个月、12个月和24个月记录修复牙的临床附着水平(CAL)、探诊深度(PPD)、探诊出血(BoP)和牙龈指数(GI)评分,以及全口牙列的菌斑指数(PlI)和牙周筛查指数(PSI)值。
治疗两年后,记录的CAL、PPD、BoP、GI、PlI和PSI评分显示,20颗治疗牙中有18颗牙周状况健康。两颗牙因新的创伤再次发生裂片骨折。
在2年的时间跨度内,牙周健康的冠根折裂牙进行粘结性裂片再附着对牙周健康没有不利影响。
