Impact of nonsurgical and antibiotics treatment on periodontitis

Background: Periodontitis is one of the most prevalent chronic inflammatory noncommunicable and multifactorial diseases. Objectives: The present study was aimed to detect the effect of systemic antibiotics as disjunctive to nonsurgical treatment of generalized periodontitis (grade I and grade II) on the bacterial count and clinical periodontal parameters. Materials and Methods: Subgingival plaque samples were collected from 40 patients with generalized periodontitis, 20 patients were treated with scaling and root planning only, and 20 patients were treated with a combination of ciprofloxacin 500 mg and metronidazole 500 mg with scaling and root planning. Moreover, 20 samples were collected from healthy patients as a control group. Specific periodontal pathogen genes for Tannerella forsythia (BspA, CIpB genes) were identified using real time polymerase reaction (RT-PCR). Results: In this study, 120 samples were detected for the presence of T. forsythia by RT-PCR technique, and the specific ClpB, and BspA primers’ genes were used for the amplification of a fragment of these genes for the identification of T. forsythia. The results showed that the presence of ClpB and BspA in all (100%). BspA and ClpB showed a decrease but non-significant differences before and after treatment, whereas the periodontal parameter, probing pocket depth, plaque score, and bleeding on probing showed a significant decrease after treatment except clinical attachment lose showing a non-significant difference. Conclusion: Clinical treatment (scaling and root planning) is often helpful in the treatment of generalized periodontal disease (grade I and grade II) without the need for antimicrobial therapy as soon as possible.
