Summary
Calcium hydroxide (Ca(OH)2) paste shows promise as a resorbable root canal filling material in primary molars. This pilot study found Ca(OH)2 successful, with reduced radiolucency and no adverse effects on permanent teeth.
Area of Science:
- Pediatric Dentistry
- Endodontics
- Biomaterials
Background:
- Zinc oxide eugenol (ZnOE) is a common root canal filling material for primary teeth.
- ZnOE is non-resorbable, potentially causing issues with permanent tooth development.
- An alternative, resorbable material is needed.
Purpose of the Study:
- To evaluate calcium hydroxide (Ca(OH)2) paste as a resorbable root canal filling material in primary molars.
- To compare its efficacy against ZnOE, focusing on resorbability and effects on succedaneous teeth.
Main Methods:
- A pilot study involving five mandibular primary molars.
- Ca(OH)2 paste used as root canal filling material.
- Six-month clinical and radiographic follow-up at 2-month intervals.
Main Results:
- Successful outcomes with Ca(OH)2, noted by absence of pain and tenderness.
- Radiographic evidence showed a decrease in periradicular radiolucency size.
- Complete healing of periradicular radiolucency observed in two teeth.
- Ca(OH)2 paste depletion occurred before physiological root resorption in two cases.
Conclusions:
- Ca(OH)2 paste is a potentially successful and resorbable alternative to ZnOE for primary molar root canal fillings.
- Further research is warranted to confirm long-term efficacy and optimal usage protocols.
