Phase 3

Conditions
Apical Periodontitis
Interventions
Registration Number
NCT03700788
Lead Sponsor
University of Southern California
Brief Summary

This is a Pilot Phase III single-blind randomized controlled clinical trial in patients, aged 18 years and older, presenting with symptoms of apical periodontitis. The overall goal is to assess whether 2% Chlorhexidine (CHX) is superior to Calcium Hydroxide in reducing interappointment pain.

Detailed Description

This is a Pilot Phase III single-blind randomized controlled clinical trial in patients, aged 18 years and older, presenting with symptoms of apical periodontitis. Patients will be treated with one of two current clinically-used medications, 2% chlorohexidine (intervention) vs. calcium hydroxide (standard-of-care). One week following treatment (+/- 2 days), patients will return for reevaltuion of apical periodontitis symptoms, via patient's pain perception after a bite test.

The primary objective of the proposed study is to determine if there is a difference in 7-day (+/- 2) post-procedure apical periodontitis following randomization to either 2% chlorohexidine vs. calcium hydroxide paste among patients presenting with symptoms of apical periodontitis. Additionally, the investigators will assess the number of adverse events that occur in each treatment group to determine if there appears to be a difference across groups, descriptively.

Primary Outcome Measures
NameTimeMethod
2% Chlorhexidine (CHX) vs CaOH2 (CH) Calcium Hydroxide Paste as an Intracanal Medicament.7 days (+/- 2 days) post treatment

The endpoint for the proposed study will be self-reported pain post-bite test, as recorded on the visual analog scale (VAS) 7 (+/- 2) days post treatment. We will be using the Visual Analog Scale (range 1-100) and plan to analyze this as a continuous variable to maintain maximum statistical power.

Secondary Outcome Measures
NameTimeMethod
Is 2% Chlorhexidine (CHX) better than Calcium Hydroxide in terms of producing fewer adverse events?7 days (+/- 2 days) post treatment

Secondarily, we will evaluate descriptively the proportion of adverse events in the two treatment groups.
