Chronic periodontitis is nowadays popularly regarded as Dysbiosis, [1] which causes destruction of tissues rich in collagen like periodontal ligament, alveolar bone and gingival connective tissue. The oral biofilm comprises many periodontal pathogens better regarded as ‘triggers’ in causing chronic periodontitis. Since, not everyone will be affected in the same manner due to periodontal pathogens. Some might not elicit a host response while, the others might have exaggerated response. So, host modulation therapy came into existence to counteract the exaggerated host response. The chemically modified tetracyclines (CMTs) have emerged to inhibit the inflammatory response or to reduce the collagenolytic activity of host. Though a derivative of tetracyclines, it still lacks an antimicrobial action and hence, can be used for periodontitis for longer duration with no adverse effects of gastrointestinal toxicity which parent tetracyclines have.

ABSTRACTObjective: Periodontitis, a chronic inflammatory disease characterized by destruction of the periodontal ligament and alveolar bone is the sixthcomplication of diabetes mellitus. Periodontal treatment that reduces gingival inflammation aids in the control of hyperglycemia. Therefore, thepresent study was designed to determine the effect of treating chronic periodontitis with oral antibiotics azithromycin and metronidazole on the levelof serum glycated hemoglobin in type-II diabetic patients.Methods: This prospective observational study was carried out in the dental department of a tertiary care hospital for 9 months. Clinical andbiochemistry reports of 90 patients were collected in designed case report forms. All statistical analyses were performed using IBM Statistical Packagefor Social Sciences 17 and Graph Pad Prism 7.0.Results: Significant reduction in all the clinical and dental parameters was comparatively higher in patients who received azithromycin than inpatients who received metronidazole and scaling and root planning alone.Conclusion: Periodontal therapy with oral azithromycin can be employed as a supportive strategy for the management of diabetes mellitus.Henceforth, prevention and control of periodontal disease along with antibiotics must be considered an integral part of glycemic control. However,due to the lesser sample size in this study, further investigations are required to confirm the effect of periodontal therapy on systemic diseases.Keywords: Periodontitis, Azithromycin, Metronidazole, Glycemic control, Diabetes mellitus.

Significant Difference

The tissue engineering approach for periodontal tissue regeneration using a combination of stem cells and scaffold has been vastly developed. Mesenchymal Stem Cells (MSCs) seeded with Bovine Teeth Scaffold (BTSc) can repair alveolar bone damage in periodontitis cases. The alveolar bone regeneration process was analyzed by micro-computed tomography (µ-CT) to observe the structure of bone growth and to visualize the scaffold in 3-Dimensional (3D). The purpose of this study is to analyze alveolar bone regeneration by µ-CT following the combination of MSCs and bovine teeth scaffold (MSCs-BTSc) implantation in the Wistar rat periodontitis model. Methods. MSCs were cultured from adipose-derived mesenchymal stem cells of rats. BTSc was taken from bovine teeth and freeze-dried with a particle size of 150-355 µm. MSCs were seeded on BTSc for 24 hours and transplanted in a rat model of periodontitis. Thirty-five Wistar rats were made as periodontitis models with LPS induction from P. gingivalis injected to the buccal section of interproximal gingiva between the first and the second mandibular right-molar teeth for six weeks. There were seven groups (control group, BTSc group on day 7, BTSc group on day 14, BTSc group on day 28, MSCs-BTSc group on day 7, MSCs-BTSc group on day 14, MSCs-BTSc group on day 28). The mandibular alveolar bone was analyzed and visualized in 3D with µ-CT to observe any new bone growth. Statistical Analysis. Group data were subjected to the Kruskal Wallis test followed by the Mann-Whitney (p <0.05). The µ-CT qualitative analysis shows a fibrous structure, which indicates the existence of new bone regeneration. Quantitative analysis of the periodontitis model showed a significant difference between the control model and the model with the alveolar bone resorption (p <0.05). The bone volume and density measurements revealed that the MSCs-BTSc group on day 28 formed new bone compared to other groups (p <0.05). Administration of MSCs-BTSc combination has the potential to form new alveolar bone.

Objectives: The aim of this clinical trial was to evaluate the additional benefit of using guided tissue regeneration (GTR) with autogenous cortical bone (ACB) grafting versus ACB grafting alone for the regenerative treatment of intraosseous periodontal defects.Methods: Via a split-mouth design, 12 patients with chronic periodontitis (five men, seven women; mean age, 45.3±4.6 years) who had probing pocket depths (PPDs) of ≥6 mm following initial periodontal therapy were randomly assigned to two treatments in contralateral areas of the dentition: a combination of ACB grafting and GTR (with a absorbable membrane of polylactic acid) or ACB grafting alone. The compared parameters were preoperative and 6-month postoperative PPDs, clinical attachment levels (CALs), and radiographic alveolar bone heights.Results: Both treatment modalities resulted in significant changes in the postoperative measurements from the preoperative values (P<.01). The reduction in the PPDs, gain in the CALs, and gain in the radiographic alveolar bone heights were 4.58±1.08, 4.25±1.06, and 5.50±2.24 mm in the patients treated with ACB grafting and GTR and 4.92±1.00, 4.50±0.80, and 5.92±1.83 mm in those treated with ACB grafting alone, respectively. The differences between the treatments were not statistically significant (P>.05).Conclusions: Within the study limitations, both ACB grafting with GTR and ACB grafting alone lead to significant improvements in clinical and radiographic parameters at 6 months postoperatively. The combined approach does not provide any additional benefit for treating intraosseous periodontal defects. (Eur J Dent 2010;4:403-411)

Objective: To evaluate bone regeneration in alveolar defects treated with human umbilical cord–derived mesenchymal stem cells (hUCMSCs), hydroxyapatite/chitosan/gelatin (HA/CS/Gel) scaffold, and bone morphogenic protein-2 (BMP-2) in Capra hircus models. Design: Randomized posttest-only control group design. Setting: Animal Hospital at Bogor Agricultural Institute. Participants: Healthy and equally treated 24 female Capra hircus/goats. Intervention: Animals were randomly assigned to 3 experimental group design (iliac crest alveolar bone graft/ICABG [control], HA/Cs/Gel+BMP-2 [ Novosys], and HA/Cs/Gel+BMP-2+UCMSCs). Graft materials were implanted in surgically made alveolar defects. Main Outcome Measures: Postoperative functional score and operating time were assessed. New bone growth, bone density, inflammatory cells recruitment, and neoangiogenesis were evaluated based on radiological and histological approach at 2 time points, week 4 and 12. Statistical analysis was done between treatment groups. Results: Operating time was 34% faster and functional score 94.5% more superior in HA/Cs/Gel+BMP-2+hUCMSC group. Bone growth capacity in HA/Cs/Gel+BMP-2+UCMSCs mimicked ICABG, but ICABG showed possibility of bone loss between week 4 and 12. The HA/Cs/Gel+BMP-2+UCMSCs showed early bone repopulation and unseen inflammatory cells and angiogenesis on week 12. Discussion and Conclusion: The HA/Cs/Gel+BMP-2+hUCMSCs were superior in enhancing new bone growth without donor site morbidity compared to ICABG. The presence of hUCMSCs in tissue-engineered alveolar bone graft (ABG), supported with paracrine activity of the resident stem cells, initiated earlier new bone repopulation, and completed faster bone regeneration. The HA/Cs/Gel scaffold seeded with UCMSCs+BMP-2 is a safe substitute of ICABG to close alveolar bone defects suitable for patients with cleft lip, alveolus, and palate.
