Summary
Intermittent guided endodontics preparation with irrigation minimizes root surface temperature increase, similar to conventional methods. Continuous guided preparation significantly elevates root surface heat, potentially harming the tooth.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Root surface temperature elevation during endodontic procedures can impact tooth vitality.
- Conventional post preparation and newer guided endodontics techniques require evaluation for thermal effects.
Purpose of the Study:
- To compare temperature development on root surfaces during continuous and intermittent guided endodontics preparations versus conventional post preparation.
- To assess the safety of guided endodontics regarding thermal insult to the root surface.
Main Methods:
- Extracted human teeth were divided into three groups: continuous guided endodontics (CGE), conventional post preparation (CPP), and intermittent guided endodontics (IGE).
- Preparations were performed using a universal testing machine with controlled force (10N for CGE/CPP) or intermittent steps with irrigation (IGE) to a 7mm depth.
- Root surface temperature was monitored using attached probes in a 37°C water bath.
Main Results:
- Continuous guided endodontics (CGE) resulted in significantly higher root surface temperatures (mean 42.5°C) compared to conventional post preparation (CPP) (mean 37.7°C).
- Intermittent guided endodontics (IGE) showed comparable temperature increases (mean 38.5°C) to conventional post preparation (CPP).
Conclusions:
- Intermittent preparation with irrigation during static guided endodontics effectively controls root surface temperature.
- This technique offers a safer thermal profile for guided endodontics, comparable to conventional post preparation methods.
