Ceramic Endo-crowns Versus Conventional Ceramic Crowns in Restoring Endodontically-treated Molar Teeth (Split Mouth Clinical Study)
Objectives: The aim of this study was to investigate the clinical outcome of ceramic cuspal coverage restoration (Endo-Crown) versus the conventional ceramic crown, assessing the clinical success in function, evaluating the health of periodontioum and the success of Root Canal Treatment in relation to the adequacy of coronal seal.
Methods: A group of 25 male and female patients with mean age of 30 years been enrolled in the study, each patient have received root canal treatment for 2 maxillary and 2 mandibular molars as minimum and referred to have cuspal coverage restorations. Each patient has evaluated and planned to have ceramic conventional crown and ceramic overlay (Endo-Crown) in each jaw ( split mouth protocol). Teeth preparation for both type of restorations in each patient performed by one graduate resident, total of 10 residents for the 25 patients. Patients with systematic conditions and periodontitis have been excluded; the intact unrestored molar teeth in each patient were used as control. All clinical procedures and outcome parameters were evaluated by 3 calibrated restorative faculties and one Endodontist these cases has been followed up for 2 years to investigate the clinical outcome, assessing the clinical success in function, evaluating the health of periodontioum and the success of RCT in relation to the adequacy of the coronal seal.
Results: all patients were examined at all the recalls during the 2 years study period; statistically there was no difference for the plaque and gingivitis scores. No secondary caries was detected around restoration margins though some patients have developed non cavitated lesions in different teeth. Durability and integrity of the margins were evaluated and 2 Endo-Crowns have had acceptable defects, 2 Endo-Crowns were lost and recemented with the same bonding procedure.
Conclusions: Cuspal coverage restorations for endo-treated molar teeth with ceramic bonded overlay system have shown a very succefull treatment option with minimal procedural risk and minimum stress distribution on the remaining tooth structures. Providing the mechanical and esthetic rehabilitation of Endo-treated molar teeth with no risk of Macro-mechanical retention features.
