Cuspal reduction in MOD Cavity in endodontically treated teeth
No cuspal reduction in endodontically treated teeth
Cavity design is of prime importance for the restoration of endodontically treated teeth. The cavity design plays an important role in the protection of the remaining tooth structure as well as the restoration. Cuspal reducuction and further coverage by the CAD/CAM generated indirect resin composite restoration has been proved in literature by the retrospective study done by (Chrepa V et al 2014) which studied 189 posterior endodontically treated teeth receiving indirect composite onlays with a median follow up time of 37 months and suggested this type of restoration as a viable option with 100% tooth survival and 96.8% restoration survival.
In the present study, choosing the comparator to be the cavity design without cuspal reduction and further coverage (inlay) is done as an attempt to reduce the application of inlays in endodontically treated teeth. In accordance to the in-vitro study done by (M. D. Al Amri et al 2016) which tested the fracture resistance of endodontically treated mandibular first molars with conservative access cavity and different restorative techniques, catastrophic failures were highest in the composite group (100%), followed by the inlay and the amalgam groups (91.67%) and this was referred to the adhesive bonding mechanism of the composite restoration and the wedging effect of the inlay and the amalgam restorations (Rivera EM andWalton RE 2015)
