Impact of endodontic post material on longitudinal changes in interproximal bone level: a randomized controlled pilot...

Area of Science:

• Dental materials science
• Periodontology
• Restorative dentistry

Background:

• Severely damaged endodontically treated teeth often require post-endodontic restoration.
• The choice of post material (e.g., glass fiber vs. titanium) may influence the surrounding alveolar bone levels.
• Understanding this impact is crucial for long-term periodontal health and restoration success.

Purpose of the Study:

• To compare the effects of glass fiber posts versus titanium posts on interproximal bone levels.
• To evaluate the impact of endodontic post material on periodontal support in severely damaged teeth.

Main Methods:

• A randomized controlled trial involving 38 participants with glass fiber (n=18) and titanium (n=20) posts.
• Radiographs were taken at baseline and 36-72 months post-placement.
• Interproximal bone level changes (mesial and distal) were measured using image-editing software and analyzed statistically.

Main Results:

• Both glass fiber and titanium posts showed minimal interproximal bone loss over a mean follow-up of 50-54 months.
• No statistically significant differences in bone level changes were observed between the two post materials.
• The overall difference in bone loss between post materials was negligible (0.10 mm).

Conclusions:

• Endodontic post material rigidity does not impact alveolar bone support around severely damaged, endodontically treated teeth.
• Restorations with either glass fiber or titanium posts can maintain stable periodontal bone support, indicating good periodontal health.
