简要总结
The use of full cuspal coverage restoration for the management root treated teeth was advocated by many clinical studies and supported by systematic reviews. However, most of the studies did not take into account the amount of tooth structure remaining before providing cuspal coverage. The strength and fracture resistance of the tooth has been shown to be positively correlated with the amount of tooth structure remaining. A more conservative treatment option could be selected for a root treated tooth with good amount of remaining tooth structure such as direct restorations.
The aims of this randomized clinical trial is to compare the survival and success of root treated teeth with occlusal cavities and at least three intact axial walls, when restored through the use of indirect full cuspal coverage restorations vs direct composite resin restorations.
详细描述
The management of posterior endodontically treated teeth (ETT) is still to this day considered a controversial topic.The use of full cuspal coverage restoration for the management ETT was advocated by many clinical studies and supported by systematic reviews. However, most of the studies did not take into account the amount of tooth structure remaining before providing cuspal coverage. An ETT tooth with an MOD cavity will be at a higher risk of fracture than an ETT tooth with just an occlusal cavity. Managing both with cuspal coverage could be considered an overtreatment and an unnecessary removal of tooth structure. The strength and fracture resistance of the tooth has been shown to be positively correlated with the amount of tooth structure remaining. A more conservative treatment option could be selected for an ETT with good amount of remaining tooth structure such as direct restorations.
The aims of this randomized clinical trial is to compare the survival and success of ETT with occlusal cavities and at least three intact axial walls, when restored through the use of indirect full cuspal coverage restorations vs direct composite resin restorations.
The groups are:
Group 1: Managed with direct intracoronal composite resin restoration. Group 2: Managed with a direct composite resin restoration, followed by an indirect full coverage restoration.
Patients will be recalled at 1 year, 3 years and 5 years.
