Polyethylene terephthalate clamps: Optimization in endodontic and restorative practices

Area of Science:

• Dental Materials Science
• Radiology in Dentistry

Background:

• Innovations in dental instruments are crucial for optimizing procedures like absolute isolation.
• The gold standard in isolation significantly impacts restorative and endodontic treatment quality.
• Radiopacity is a key characteristic for evaluating dental instruments used in radiographic procedures.

Purpose of the Study:

• To evaluate the radiopacity of novel polyethylene terephthalate polymer clamps.
• To compare the radiopacity of these polymer clamps against conventional metal clamps.

Main Methods:

• Developed polyethylene terephthalate clamps (Patent application #PI0901719-4).
• Radiographs were taken of five polymer and five metal clamps alongside an aluminum scale using standard settings (60 kVp, 0.06s).
• Optical density was measured using DBWin 5.0.4 software, and differences were analyzed with Student's t-test (p<0.05).

Main Results:

• Polyethylene terephthalate polymer clamps exhibited significantly lower radiopacity compared to conventional metal clamps (p<0.05).

Conclusions:

• Polyethylene terephthalate clamps possess lower radiopacity than their metal counterparts.
• This lower radiopacity may influence their suitability in specific dental applications requiring high visibility on radiographs.
• Further research could explore modifications to enhance radiopacity or assess clinical implications.
