Clinical picture of combination therapy [metronidazole sustained release film with minocycine hydrochloride] in preiodentitis

ABSTRACT

This paper aimed to study the effect of metronidazole sustained-release film combined with minocycline hydrochloride on treating periodontitis. 138 patients with chronic periodontitis were collected and randomly divided into control group and observation group [each of 69 cases]. Patients in control group were treated by using minocycline hydrochloride, while those in observation group were treated using metronidazole sustained-release film with minocycline hydrochloride, and each group with 4 weeks of treatment. Then we observed the periodontal mend matters, therapeutic effect, adverse reaction and relapse situation of patients in two groups. Results showed that compared with the prior treatment, the gingival index, dental plaque index, odontoseisis index and pocket depth of patients in two groups was significantly reduced. Moreover, the reduction range in observation group was significantly larger and the curative effect was superior to that in control group. Therefore, metronidazole sustained-release film combined minocycline hydrochloride can evidently improve patients' periodontal status, enhance drug therapeutic effect. It has less adverse reaction and low relapse rate, thus is worthy of clinical promotion
