Summary
Nonsurgical endodontic treatment successfully addressed a mandibular molar with three distal roots. Computer-aided rapid prototyping (CARP) effectively visualized and documented this unusual root anatomy.
Area of Science:
- Dentistry
- Endodontics
- Medical Imaging
Background:
- Unusual root anatomy presents challenges in endodontic therapy.
- Accurate visualization of complex root structures is crucial for successful treatment.
Purpose of the Study:
- To document and manage a case of nonsurgical endodontic therapy on a mandibular molar with three distal roots.
- To evaluate the utility of computer-aided rapid prototyping (CARP) in visualizing complex root anatomy.
Main Methods:
- Nonsurgical endodontic therapy performed with magnification.
- Acquisition of 3D digital data (DICOM) using CT scanning.
- Fabrication of an actual-sized tooth model using computer-aided rapid prototyping (CARP) with starch.
Main Results:
- Successful nonsurgical endodontic therapy of the affected molar.
- CARP model clearly depicted three distinct distal roots: distobuccal, distolingual, and middle distal.
- 3D digital visualization accurately represented the complex root anatomy.
Conclusions:
- CARP is a valuable imaging technology for documenting unusual root anatomy in clinical dentistry.
- Advanced imaging and modeling techniques aid in managing complex endodontic cases.
