Effects of non-surgical treatment modalities on peri-implantitis / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effects of local-delivery of 25% metronidazol gel and mechanical cleaning using ultrasonic carbon fiber tip on dental implants with peri-implantitis.</p><p><b>METHODS</b>27 implants with peri-implantitis were randomly assigned to receiving either 25% metronidazol gel treatment or carbon fiber tip ultrasonic scaling. All parameters including plaque index (PLI), probing depth (PD) of pocket, sulcular bleeding index (SBI), and BANA enzyme analysis were measured at baseline, 1, 2, 6 and 12 weeks after treatment.</p><p><b>RESULTS</b>Statistically significant decrease (P < 0.05) in SBI, BANA test and PLI occurred in both treatment groups at all time intervals compared to baseline. PD had a decreasing tendency in both groups, but only metronidazole group reached statistically significant level (P < 0.05) at 2 and 6 week intervals compared to baseline. None of the treatment modalities produced any side effects on the implant and peri-implant tissues.</p><p><b>CONCLUSIONS</b>Both 25% metronidazol gel and mechanical cleaning using ultrasonic carbon fiber tip can be safely and effectively used in the treatment of peri-implant diseases.</p>
