Different pharmacological solutions in intracanal irrigation

Area of Science:

• Dentistry
• Endodontics
• Microbiology

Background:

• Intracanal irrigation is crucial for disinfecting and cleaning root canals during endodontic therapy.
• Common irrigants include sodium hypochlorite (NaOCl), hydrogen peroxide (H2O2), chlorhexidine (CHX), and normal saline.
• Evaluating alternative or combined irrigation protocols is essential for optimizing endodontic treatment outcomes.

Purpose of the Study:

• To assess the clinical and radiological efficacy of normal saline (0.9% NaCl) irrigation combined with sequential hydrogen peroxide (H2O2) and sodium hypochlorite (NaOCl) in endodontic therapy.
• To compare the outcomes of this specific irrigation protocol against a control group.

Main Methods:

• A prospective study involving 104 patients undergoing endodontic therapy for mature permanent teeth over one year.
• Patients were randomly allocated into two equal treatment groups.
• Outcomes measured included post-obturation pain, swelling, analgesic use, and radiological evaluation at eight weeks.

Main Results:

• No statistically significant differences were observed in post-obturation pain, swelling, analgesic use, or radiological outcomes between the two groups.
• Both irrigation protocols demonstrated comparable clinical and radiological success rates in this study.

Conclusions:

• The sequential irrigation protocol involving normal saline (0.9% NaCl), hydrogen peroxide (H2O2), and sodium hypochlorite (NaOCl) appears to be as effective as conventional methods for endodontic therapy.
• Further research with larger sample sizes and longer follow-up periods is recommended to confirm these findings.
