Investigating the effects of disinfectants on pain and success in dental procedures

The Effect of Sodium Hypochlorite and Chlorhexidine as Cavity Disinfectants on the Post Operative Pain and Success of Partial Caries Removal in Deep Carious Lesion With Moderate Pulpitis in Permanent Teeth: A Randomized Controlled Trial

Not applicable Interventional Postgraduate Institute of Dental Sciences Rohtak · NCT06836882

This study is testing whether using sodium hypochlorite or chlorhexidine as disinfectants during dental procedures can help reduce pain and improve success for patients with deep cavities compared to using saline.

What this trial studies

This study aims to evaluate the effectiveness of sodium hypochlorite and chlorhexidine as cavity disinfectants during partial caries removal in patients with deep carious lesions and moderate pulpitis. The research will compare the clinical and radiographic outcomes of using these disinfectants against saline in mature permanent mandibular molars. Patients will be monitored for post-operative pain levels and treatment success over a 12-month follow-up period. The study includes a detailed assessment of pain reduction at 24-hour intervals for the first week post-procedure.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with restorable mature permanent mandibular molars exhibiting deep caries and moderate pulpitis.

Not a fit: Patients with vertical root fractures, root perforations, or those classified as ASA-3 or ASA-4 may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management and treatment outcomes for patients undergoing dental procedures for deep carious lesions.

How similar studies have performed: Previous studies have shown varying degrees of success with similar disinfectant approaches in dental treatments, but this specific comparison is novel.
