Condition(s) targeted: Chronic Periodontitis

Intervention: minocycline (Drug); surface and root planning (Procedure)

Phase: Phase 4

Status: Completed

Sponsored by: Zhejiang University

Official(s) and/or principal investigator(s):
Shuli Deng, Master, Principal Investigator, Affiliation: Affiliated Hospital of Stomatology, Medical College, Zhejiang University


To evaluate the respective or combinatory efficacy of locally delivered 2% Minocycline (MO) and surface and root planning (SRP) by assessing both clinical parameters and the loads of four main periodontal pathogens in treating chronic periodontitis.

Clinical Details

Official title: The Response of Periodontal Pathogens to the Respective or Combined Treatment of Scaling and Root Planning and Locally Delivered Minocycline in Patients With Chronic Periodontitis- a Short-term Randomized Clinical Trial

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Pocket depth

Secondary outcome:

bleeding on probing

Bacterial load

Detailed description: In this randomized clinical trial, we will evaluate the respective or combinatory efficacy of minocycline and scaling and root planning in the aspects of both clinical parameters [Pocket depth (PD) and sulcus bleeding index (SBI)] and the loads of four main periodontal pathogens [Aggregatibacter actinomycetemcomitans (Aa), Fusobacterium nucleatum (Fn), Porphyromonas gingivalis (Pg) and Prevotella intermedia (Pi)]. Real-time quantitative PCR (qRT-PCR) will be used as a powerful tool with high sensitivity and specificity to quantitatively assess target periodontal bacteria in a period of 7 days. We will also try to correlate the reduction of either total or respective bacteria with the improvements of clinical parameters, with an aim to uncovering the potential microbiological mechanism accounting for the efficacy of a therapy


Minimum age: N/A. Maximum age: N/A. Gender(s): Both.


Inclusion Criteria:

- diagnosed with moderate or severe chronic periodontal disease, and exhibited bleeding

on probing and attachment loss, with radiographic alveolar bone loss in four or more teeth Exclusion Criteria:

- pregnant, had used antibiotics within the last 3 months, had periodontal therapy in

the past 6 months or had systemic diseases such as heart disease or hypertension
