Endodontically treated posterior teeth restored with or without crown restorations: A 5-year retrospective study of survival rates from fracture
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.
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.
