Department of Periodontology and Oral medicine, Medical faculty, University of Nis, Nis, Serbia.

Objectives: The use of local probiotics in the therapy of periodontitis is reflected in their ability to antagonize periodontopathogens and modulates the immune response of the host to the presence of pathogenic microorganisms. The aim of this study was to investigate the use of local probiotics in the treatment of periodontitis as an adjunctive therapy to scaling and root planning (SRP).

Methods: The study involved 80 patients diagnosed with periodontitis. All participants underwent SRP therapy. Semi-solid probiotic was then locally applied to the periodontal pocket in randomly selected patients for the test group (40 of them). The other 40 patients were in the control group. Clinical parameters including periodontal pocket depth (PPD), bleeding on probing (BOP) and plaque index (PI) were measured at baseline, and at 7 and 30 days after treatment.

Results: Seven days after the applied therapy in the test and control group, there was a significant decrease in the values or BOP (p < .001), while the values of other parameters did not show a statistically significant difference (p < .05). One month after the therapy in both groups, there was a statistically significant difference in the values of all clinical parameters (p < .001).

Conclusions: Based on the results of this pilot study, it can be said that, during periodontal treatment, topical application of probiotics in combination with SRP increases the effectiveness of conventional non-surgical therapy of periodontitis.

Therapeutic efficacy of clindamycin gel as an adjunct to scaling and root planing therapy in chronic periodontal disease.

Acta Clin Croat 2015 Mar;54(1):46-51

Clindamycin, a lincosamide antibiotic, has been under-recognized as an antimicrobial agent for use in dentistry. The aim of the present work was to evaluate clinical efficacy of 2% clindamycin gel in addition to the basic mechanical periodontal therapy. At baseline, scaling and root planing (SRP) was performed at all 50 subjects (control group and test group). Clindamycin gel was applied after SRP only in the test group. Clinical measurements including periodontal pocket depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP) and plaque index (PI) were done at baseline, and at 3 and 6 months after treatment. Compared to baseline, the PPD and CAL values significantly decreased in the test group (p < 0.05) and were statistically lower (p < 0.05) compared to control group. PPD reduction of 2.42 mm was obtained in the test group and could be generally considered as clinically significant. A PPD reduction greater than 2 mm indicated that clindamycin gel could be used efficiently as an adjunct to SRP. Also, between-group difference in BOP and PI scores was statistically significant 6 months after treatment. In conclusion, the application of clindamycin gel in combination with SRP enhanced the efficacy of non surgical periodontal therapy in reducing pocket depth and improving attachment levels in chronic periodontitis subjects and had additional benefits over mechanical therapy alone.

Effect of periodontal treatment in renal transplant recipients.

Med Princ Pract 2014 20;23(2):149-53. Epub 2013 Dec 20.

Department of Periodontology and Oral Medicine, Medical Faculty, University of Nis, Nis, Serbia.

Objective: To evaluate the effect of periodontal treatment on gingival overgrowth in a group of renal transplant patients.

Subjects And Methods: Twenty-five renal transplant recipients receiving immunosuppressive therapy with cyclosporine A (CsA) were randomly assigned to 2 groups. Group 1 (n = 15) included patients who had been specifically referred to a dental clinic to prevent gingival overgrowth and were given full periodontal therapy. Group 2 (n = 10) was comprised of patients who did not receive any professional periodontal cleaning. Patients from both groups were examined to determine their periodontal status before and after 3, 6 and 12 months in terms of their plaque index, gingival index and gingival overgrowth. During the examination, their overall health was stable.

Results: For group 1, the scores were 1.89 (baseline), 0.98 (6 months) and 0.56 (12 months), and hence there were significant reductions (p = 0.0001). The gingival indices were 1.71 (baseline), 0.76 (6 months) and 0.35 (12 months), and the reductions were also significant (p = 0.0001). A significant association was observed between poor oral hygiene and the degree of gingival overgrowth. The 1-year post-treatment follow-up showed that patients in group 1 did not develop gingival overgrowth due to the use of CsA as group 2 did without prior periodontal therapy.

Conclusion: Oral hygiene status was the most important variable related to the development and degree of gingival overgrowth due to the use of CsA.

RP-HPLC assay of doxycycline in human saliva and gingival crevicular fluid in patients with chronic periodontal disease.

J Pharm Biomed Anal 2013 May 20;78-79:170-5. Epub 2013 Feb 20.

Department of Pharmacy, University of Niš, Faculty of Medicine, Bulevar dr Zorana Đinđića 81, 18000 Niš, Serbia.

A reversed-phased HPLC method with fluorescence detection was optimized and validated for determination of DOXY in human saliva and gingival crevicular fluid (GCF) with tetracycline as internal standard. Single step extraction with acetonitrile for both types of samples was performed. The separation was achieved at Zorbax Extend-C18 analytical column at 30°C. Mobile phase was consisted of an aqueous phase containing magnesium acetate, ammonium acetate, Na₂EDTA, triethyl-ammonium acetate buffered to pH 7.5 with ammonium hydroxide solution and acetonitrile. The volume ratio of the buffered water mixture of salts and acetonitrile was 86:14. Fluorescence detector was set at λex=380 nm and λem=520 nm. Under the optimized experimental conditions, good linearity was found in the range of 5.0-250.0 ng/mL for GCF with LOD of 1.63 ng/mL and LOQ of 4.93 ng/mL and 20.0-500.0 ng/mL for saliva with LOD of 6.36 ng/mL and LOQ of 19.28 ng/mL. This method was successfully applied for determination of DOXY in saliva and GCF obtained from patients with chronic periodontal disease.
