Abstract:

BACKGROUND: Experimental proof for the efficacy, safety, and immunological assessment is needed when minocycline is used for root canal disinfection.
OBJECTIVE: To investigate the effect of minocycline for root canal disinfection on levels of interleukin-17 in apical exudates of periapical periodontitis and periapical exudate volume.
METHODS: Sixteen patients with acute periapical periodontitis (16 teeth) scheduled for root canal therapy were enrolled and randomly divided into calcium hydroxide and minocycline groups, respectively, followed by root canal disinfection. One week after disinfection, periapical index, periapical exudate volume and interleukin-17 level were detected prior to the root canal filling. Another 16 patients with normal pulp vitality (16 teeth) scheduled for single root canal filling were enrolled as control group, in which periapical index, periapical exudate volume and interleukin-17 level were detected.
RESULTS AND CONCLUSION: The periapical exudate volume and interleukin-17 level in the calcium hydroxide and minocycline groups were significantly higher than those in the control group (P < 0.05). The periapical index and interleukin-17 level in the calcium hydroxide and minocycline groups were decreased significantly at 1 week after root canal disinfection (P < 0.05), while there was no difference between these two experimental groups in the periapical index, periapical exudate volume and interleukin-17 level. To conclude, the use of minocycline significantly reduces interleukin-17 level and periapical exudate volume, and thus achieves effective outcomes in periapical disease.
