Summary
Sodium hypochlorite is a widely used endodontic irrigant. This review covers its properties, cost-effectiveness compared to domestic alternatives, and provides guidelines for safe clinical use and disposal.
Area of Science:
- Dentistry
- Endodontics
- Biochemistry
Background:
- Sodium hypochlorite has been a staple endodontic irrigant for over 70 years.
- Its chemical properties and production methods are well-established in dental practice.
Purpose of the Study:
- To review the chemical properties and production of commercial sodium hypochlorite.
- To compare domestic bleaches and infant sanitizers as cost-effective alternatives.
- To provide guidelines for the clinical application, storage, handling, and disposal of sodium hypochlorite.
Main Methods:
- Literature review of sodium hypochlorite properties and applications.
- Comparative cost analysis of commercial sodium hypochlorite versus domestic alternatives.
- Evaluation of ease of use for different sodium hypochlorite sources.
Main Results:
- Sodium hypochlorite is a cost-effective endodontic irrigant.
- Domestic bleaches and infant sanitizers offer alternatives, with Milton recommended for 1% solutions.
- The cost of irrigation delivery systems significantly exceeds the irrigant cost.
Conclusions:
- Sodium hypochlorite remains a primary and economical choice for endodontic irrigation.
- Careful consideration of cost, availability, and specific clinical needs can guide irrigant selection.
- Adherence to proper handling, storage, and disposal protocols is essential for safe and effective use.
