Abstract:

BACKGROUND: In recent years, the topical use of antibiotics in periodontal pockets has become a new regimen for the prevention and treatment of peri-implantitis.
OBJECTIVE: To analyze the effectiveness of minocycline hydrochloride ointment in the treatment of peri-implantitis.
METHODS: Eighty cases of peri-implantitis, 38 males and 42 females, aged 20-32 years, were divided into two groups: experimental group (n=40) was given minocycline hydrochloride ointment into the bottom of periodontal pockets, once a week; and control group (n=40) was injected iodine glycerol into the bottom of periodontal pockets, once a week. Meanwhile, patients without peri-implantitis were selected as normal control group (n=40). After 4 weeks of treatment, we detected probing index, bleeding index, plaque index, detection of Prevotella melaninogenica and Streptococcus oralis in the two groups, and then statistically analyzed the clinical efficacy.
RESULTS AND CONCLUSION: (1) Before the treatment, probing index, bleeding index, plaque index, and detection rates of Prevotella melaninogenica and Streptococcus oralis were all higher in the experimental group than the normal control group (P < 0.05), but there was no significant difference between the experimental group and the control group. (2) After 4 weeks of treatment, probing index, bleeding index, plaque index, and detection rates of Prevotella melaninogenica and Streptococcus oralis in the experimental and control groups were significantly lowered (P < 0.05), but still higher than those in the normal control group (P < 0.05). In addition, these indices were also significantly lower in the experimental group than the control group (P < 0.05). (3) The clinical efficiency of the experimental group after treatment was significantly higher than that of the control group (98% vs. 75%, P < 0.05). Taken together, minocycline hydrochloride ointment as an effective treatment for peri-implantitis can inhibit the colonization of Prevotella melaninogenica and Streptococcus oralis.
