Background: Endocrowns are created from mono-block porcelain containing the invaded coronal portion of the apical projection that fills the space of the pulp chamber, and probably the entrances of the root canal. This makes restoring endodontically extensive damaged teeth challenging and difficult.
Methods: This is a retrospective chart review study essentially compiling and analyzing records from all patients consecutively treated with endocrowns which was performed by residents and students, carried out in Riyadh Elm university in Riyadh.
Results: Out of 41 endo-crown cases 65.9% were successful according to follow up time and radiographic examination, and 34.1% is still under investigation. Furthermore, 51.2% were male patients while 70.7% were in the age group of 22 to 49 years. About 63.4% had treatment for the lower teeth and all the cases teeth were posterior. The period of longevity was 6 to 24 months in 51.2% of subjects.
Conclusions: Additional scientific studies and clinical examination on a larger sample size are needed to assess the long-term efficacy of endocrown. However, it appears to be a conservative and an aesthetic treatment with long-term survival benefits.
