Summary
Bone regeneration materials, including non-absorbable membranes and resorbable hydroxylapatite, significantly improved healing predictability in periradicular surgery. This study demonstrates their efficacy in periapical tissue repair over 12 months.
Area of Science:
- Dentistry
- Oral Surgery
- Regenerative Medicine
Background:
- Periradicular surgery aims to heal periapical tissues.
- Predicting healing outcomes in periradicular surgery can be challenging.
Purpose of the Study:
- To evaluate the efficacy of bone regeneration materials in periradicular surgery.
- To assess the impact of these materials on periapical tissue healing.
Main Methods:
- A comparative study involving 28 patients (30 surgical sites).
- Three groups: conventional technique, conventional technique with GoreTex membrane, and conventional technique with membrane and OsteoGen (hydroxylapatite).
- Clinical, radiographic, and histological evaluations over 12 months.
Main Results:
- Group C (membrane + OsteoGen) showed complete healing in all cases with histologic evidence of bone.
- Group B (membrane only) had 6/9 complete radiographic healing and 5/8 histologic bone regeneration.
- Group A (conventional) had lower healing rates (4/9 radiographic) and more unfavorable histology.
Conclusions:
- The conventional technique demonstrated less predictable healing.
- Non-absorbable membranes and resorbable hydroxylapatite enhanced the predictability of clinical, radiographic, and histological healing.
