Gingivitis and periodontitis are most common inflammatory diseases of supporting tissues of teeth. Role of microbial etiology and host response in progression of gingival and periodontal diseases has been well established. Because of the beneficial biological effects of ozone, due to its antimicrobial and immunostimulating effect, it is well indicated in the treatment of gingival and periodontal diseases. The objective of this article is to provide a general review about clinical applications of ozone in treatment of periodontal diseases and to summarize the available in vitro and in vivo studies in Periodontics in which ozone has been used.

Background:Anemia of chronic disease is defined as anemia occurring in chronic infections, inflammatory conditions, or neoplastic disorders which are not due to marrow deficiencies or other diseases, and occurring despite the presence of adequate iron stores and vitamins.Aims:To evaluate the relation between anemia and periodontitis by estimation of blood parameters and to assess whether periodontitis like other inflammatory conditions can lead to anemia. It is a randomized controlled clinical trial.Materials and Methods:A total of 50 healthy controls, 50 chronic generalized gingivitis, and 50 chronic generalized periodontitis patients were selected. Hemoglobin levels (Hb), erythrocyte count red blood cell, erythrocyte sedimentation rate (ESR), mean corpuscular volu e (MCV), mean corpuscular Hb (MCH) and MCH concentration (MCHC), gingival index, plaque index, probing pocket depth, and clinical attachment level were recorded. Intergroup comparison of blood parameters is by one-way ANOVA. Intergroup pair wise comparison of the three groups is by Newman–Keuls multiple post-hoc procedures. Karl Pearsons's correlation coefficient method is used for correlation between different parameters for three groups.Results:The results revealed a decrease in Hb and erythrocyte counts and increase in white blood corpuscles counts in chronic generalized periodontitis when compared to healthy controls and chronic generalized gingivitis group. There was no statistically significant difference in MCV, MCH, MCHC, and ESR among the groups.Conclusions:The treatment of periodontitis can lead to an improvement in hematocrit and other related blood parameters in chronic generalized periodontitis patients with anemia. This provides evidence that periodontitis like other chronic diseases may also cause anemia.

Context:Antimicrobial efficacy of subgingival chlorhexidine (CHX) application using two different vehicles of delivery.Aims:The aim was to evaluate the efficacy of CHX varnish and gel as an adjunct to scaling and root planing (SRP) in reducing microbial count within moderate to deep periodontal pockets.Settings and Design:Experimental parallel mouth study.Subjects and Methods:A total of 30 subjects between the age groups 25 and 55 years having moderate to severe periodontitis, with pocket depth ≥ 5 mm were selected for the study. The selected patients were randomized into three groups of 10 each. Subjects in Group 1 received SRP followed by subgingival application of CHX varnish, subjects in Group 2 received SRP followed by subgingival application of CHX gel, subjects in Group 3 received SRP alone. Subgingival plaque samples were collected to estimate mean motile and nonmotile microbial counts using dark field microscopy at baseline, 1 week, 1 month, and 3 months.Results:After 3 months, there was statistically significant reduction in nonmotile microbial count in all the three groups. Motile microbial count was significantly reduced in all the three groups till 1 month from baseline. Only subjects in Group 1 who received subgingival CHXvarnish after SRP showed a significant reduction in motile microbial count till 3 months from baseline.Conclusions:Subgingival application of highly concentrated CHX varnish following SRP is beneficial in reducing microbial count in moderate to deep periodontal pockets.

Pyogenic granuloma (PyG) is a common cause of swelling in the oral cavity during pregnancy and also as an exaggerated response to any minor trauma. The condition is frequently associated with periodontal pain and discomfort, in some cases interfering with mastication and creating esthetic problems. Six patients reported to the Department of Periodontics with gingival overgrowth in the lower anteriors. After recording the details of the patients’ oral hygiene status, all the patients were provided initial therapy with scaling and were prescribed analgesics for the reduction of pain and discomfort. After 1 week, surgical excision of the overgrowth was performed and sent for histopathological analysis. The histopathological report is suggestive of PyG.

Periodontally accelerated osteogenic orthodontics is a relatively new procedure designed to minimize the time taken for orthodontic treatment. The orthodontist avails of the aid of a periodontist to perform decortication of the bone and places bone graft for rapid orthodontic correction of malocclusion. A PubMed search was carried out to identify papers describing the procedure, and the data were organized in the current format.
