Summary
The alkasite restorative material showed increased wear and noticeable color differences compared to bulk-fill resin composite in root canal treated molars after 17 months. However, it remains a clinically acceptable option for restoring endodontically treated teeth.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
- Clinical Trials
Background:
- Root canal treated teeth require durable and aesthetically pleasing restorative materials.
- Alkasite materials offer potential benefits, but their clinical performance needs evaluation.
- Comparing alkasite with established bulk-fill resin composites is crucial for clinical decision-making.
Purpose of the Study:
- To clinically evaluate the performance of an alkasite restorative material (Cention N) versus a bulk-fill resin composite (Tetric N Ceram Bulk Fill) in molars after root canal treatment.
- To assess parameters such as retention, secondary caries, marginal adaptation, color stability, and anatomical form over 17 months.
Main Methods:
- A randomized clinical trial involving 33 patients with restored mandibular molars.
- Random allocation to either alkasite or bulk-fill resin composite restorations.
- Evaluation using United States Public Health Service criteria at 7 days, 6 months, and 17 months.
Main Results:
- The alkasite material exhibited significantly greater wear of anatomical shape (p=0.0189) and noticeable color differences from natural teeth (p=0.0000) after 17 months.
- No significant differences were observed in retention, secondary caries, marginal adaptation, or other assessed criteria between the two materials or over time (p>0.05).
Conclusions:
- The alkasite restorative material (Cention N) demonstrates clinically acceptable performance for restoring endodontically treated teeth.
- While showing increased wear and color mismatch, it presents a viable alternative restorative option.
