Abstract

Aim

The aim of the present study was to investigate survival rates from fracture of endodontically treated posterior teeth (ETT) restored with or without crowns with recall periods of up to 5 years.

Methods

ETT with single-unit crown or resin composite restorations were studied based on the inclusion criteria. Restoration, tooth structure loss, adjacent teeth, fracture, and restorability were recorded. Survival rates from fracture were calculated, and risk factors were identified.

Results

Overall, survival rate of ETT with crowns (92.2%) was significantly higher than resin composites (77.4%) (P < 0.05). ETT with one or two surface loss/es and two adjacent teeth had a high survival rate of 86.9%, which was not significantly different to ETT with crowns (P ≥ 0.05). Restoration and adjacent teeth were identified as significant factors. The majority of fractured ETT with resin composites were restorable, whereas those with crowns were unrestorable. Survival rates from unrestorable fracture were not significantly different between the crown (93.1%) and resin composite (96%) (P ≥ 0.05).

Conclusions

The survival rate from the fracture of ETT restored with crowns was significantly higher than ETT restored with resin composites, but was not significantly different to ETT with one or two ETT with one or two surface loss/es and two adjacent teeth. ETT restored with resin composites had mostly restorable fracture, whereas ETT with unrestorable fracture were similar between the two restorations.

根管治疗后牙有或没有冠修复:骨折存活率的5年回顾性研究

目的本研究的目的是调查有冠或无冠后牙根管治疗后牙(ETT)骨折的存活率，回忆期长达5年。方法根据纳入标准对单冠和树脂复合修复体进行研究。记录修复、牙齿结构损失、邻近牙齿、骨折和可修复性。计算骨折的存活率，并确定危险因素。结果整体而言，ETT带冠成活率(92.2%)显著高于树脂复合成活率(77.4%)(P <0.05)。1个或2个表面损失/es和相邻2颗牙的ETT成活率为86.9%，与有冠的ETT成活率差异无统计学意义(P≥0.05)。修复体和邻近牙齿被认为是重要的因素。采用树脂复合材料的断裂ETT大部分是可修复的，而有冠的则是不可修复的。冠状体与复合树脂的骨折不可恢复性生存率差异无统计学意义(P≥0.05)。结论牙冠修复的全牙体骨折成活率明显高于树脂复合材料修复的全牙体，但与单牙或双牙表面缺损的全牙体及相邻两牙的全牙体无显著差异。树脂复合材料修复的ETT骨折多为可恢复性骨折，而两种修复的ETT骨折不可恢复性骨折相似。

期刊介绍： Journal of Investigative and Clinical Dentistry (JICD) aims to publish quality, peer reviewed original research and topical reviews on all aspects of investigative and clinical dentistry and craniofacial research, including molecular studies related to oral health and disease. Although international in outlook, the Editor especially encourages papers from the Asia Pacific. The journal also aims to provide clinicians, scientists and students of dentistry with a knowledge transfer platform for rapid publication of reports through an international journal, which will be available free online until 2012. Its scope, therefore, is broad, inclusive and international, but with a particular focus on Asia Pacific. The Editor welcomes manuscripts in the following key thematic areas in oral and maxillofacial sciences: Community Dentistry and Oral Epidemiology, Conservative Dentistry, Dental Biomaterials, Dental Pedagogy, Endodontics and Traumatology, Implant Dentistry, Oral Biosciences, Oral and Maxillofacial Surgery, Oral Medicine, Oral Pathology and Oral Microbiology, Orthodontics, Oral Radiology, Oral Rehabilitation, Paedodontics, Periodontology and Periodontal Medicine.
