Genetic polymorphism of interleukin-12β (rs7709212) in chronic and aggressive periodontitis in a group of the Bengali population of India

Objectives: The genetic basis of periodontitis was demonstrated by formal genetic studies which were focused on a range of various candidate genes selected for their roles in the immune system like genes of the interleukins (IL). Bone proresorptive cytokines such as IL-1 and tumor necrosis factor-α are primarily regulated by a network of other T-cell derived cytokines, including IL-12 family. Specific objective of this study was to find out any association between IL-12β 3΄ untranslated region (UTR) (rs7709212) gene polymorphism and chronic as well as aggressive periodontitis (AgP) in Bengali population of West Bengal, India. Materials and Methods: A total of 88 Bengali participants of both sexes were recruited and were divided into three groups: Group A (chronic periodontitis [CP] group), Group B (AgP group), and Group C (healthy control). DNA extraction from collected peripheral venous blood was performed by phenol chloroform method and ethanol precipitation. Genotyping of extracted DNA samples was carried out for locus IL-12β 3΄UTR (rs7709212) by real time-polymerase chain reaction. Association between genotypes and cases was examined by the odds ratio with 95% confidence interval and chi-square analysis using R statistical software. Statistical significance was defined as P < 0.05. Results: On analysis of the minor allele frequencies of total periodontitis cases and control, the results were found to be statistically significant with the P = 0.03045. Conclusion: The present study suggested a strong association of single nucleotide polymorphism of IL-12β (rs7709212) with total periodontitis cases (both CP and AgP) in the present study cohort.

Association of salivary pH in patients with dental caries and periodontal disease

Background: The aims of the study was to find out the prevalence of dental caries in healthy and periodontal disease and its association with salivary pH.Methods: A total of 80 healthy subjects reporting to the department of periodontology were selected. They were divided into four groups (clinically healthy gingival, chronic generalized gingivitis, chronic generalized periodontitis, and aggressive periodontitis) with 20 subjects in each. Periodontal parameters; decayed, missing, and filled teeth (DMFT) index and salivary pH were recorded. Unstimulated whole saliva was collected according to Navazesh method. The pH of saliva was immediately measrued using a single electrode digital pH meter.Results: Based on statistical test it was seen that caries prevalence and DMFT was found out to be least in aggressive periodontitis group, along with least mean pH value, as compared to the other 3 groups, p<0.05.Conclusions: The low prevalence of caries in aggressive periodontitis can be attributed to the low pH of saliva. Salivary pH plays a vital role in the formation of microbial film, which in turn has a significant role in the pathogenesis of both dental caries and periodontitis.

Microbiological landscape of the periodontal pocket in inflammatory diseases in the periodontal tissues

Relevance. The study of the microbiological composition of periodontal pockets in inflammatory diseases of periodontal tissues is of great importance directly for the effective treatment and understanding of the pathogenetic stages of these diseases. Objective: to study the microbiological landscape of periodontal pockets with inflammatory diseases of periodontal tissues. Materials and Methods. 62 patients aged 20 to 45 years were selected and divided into groups depending on the form of periodontitis: with localized aggressive periodontitis - group №1, group №2 - with chronic generalized periodontitis, group № 3 - with exacerbation of chronic generalized periodontitis. The material for the study was taken from the periodontal pockets and examined by cultural and microbiological methods. Results and Discussion. It was found that the proportion and number of microbial associations in the periodontal pockets of different depths differs. In localized aggressive periodontitis, mainly facultative Gr+ (A. actinomycetemcomitans) and Gr- (St. aureus, Str. mitis) anaerobes were found in the periodontal pockets no more than 4 mm. In generalized chronic periodontitis of moderate degree, the same microorganisms were present in the periodontal pockets as in the localized form, but Str. mitis was more common among facultative aerobes. With the exacerbation of generalized chronic periodontitis from facultative anaerobes, St. aureus was more common and the proportion and number of A. actinomycetemcomitans significantly increased. Conclusion. According to the results of the study, the microorganisms that inhabit the periodontal pockets in inflammatory diseases of periodontal tissues mainly belong to facultative Gr+ and Gr - anaerobes, obligate Gr+ and Gr-anaerobes and yeast fungi.

Association of ABO Blood Grouping and Periodontal Disease: A Literature Review

Although the correlation between the ABO blood group and certain systematic diseases is a well-documented fact. Few studies have explored the relationship of ABO with oral disorders including periodontal diseases (PD). This literature review aimed to assess the possible association between ABO blood grouping and PD. For this purpose, we searched online databases like PubMed and google scholar with the following terms in different combinations PD, ABO blood groups, gingivitis, the prevalence of periodontitis, aggressive periodontitis, risk factors of periodontitis, Association of PD and ABO, ABO Rh factor. English version papers describing the Oral health status are covered through research that includes clinical investigations, case studies, and retrospective studies on the subject. Historic reviews, articles with unpublished data, and letters to the editors were omitted from the survey following publications. The author thoroughly checked the titles and abstracts of the papers. The complete text was thoroughly assessed, and the relevant articles were analyzed in accordance with qualifying criteria. For further original and review research, references were further reviewed. Since our targeted subject was answered by a restricted number of original research. We identified fourteen articles describing the association of ABO blood types with PD. findings of our study concluded the genetic basis of the association of ABO blood types for the development of PD. six of the research provided here showed that the blood type O can serve as a prognostic factor for the development of PD. ABO blood types and Rhesus factors can be a risk predictors in the development of PD.

Localised Aggressive Periodontitis – A Review

The term “periodontal diseases” includes any inherited or acquired disorders of the tissues that are supporting the teeth i. e Gingiva, Cementum, PDL, and Alveolar bone. The periodontal disease can be either localized or generalized. Localized aggressive periodontitis (LAgP) patients have interproximal attachment loss on at least two permanent first molars and incisors, with attachment loss on no more than two teeth other than first molars and incisors. In children and adolescents LAgP occurs without clinical evidence of systemic disease and it is characterized by the severe loss of alveolar bone around permanent teeth [10]. Most commonly the disease is localized to the permanent first molars and incisors. Aim: The aim of this review article is explain in details about aggressive periodontitis including different management aspect of the same. Methods: This paper presents a review of the aggressive periodontitis in children. An electronic search was conducted using Pub Med®/MEDLINE, and Google search using the terms: Periodontium, Localized Aggressive Periodontitis, Children and periodontal health, periodontal health in adolescents, gingival disease in children, periodontal disease in children, gingivitis, periodontitis, gingival disease and its prevalence, periodontal disease and its prevalence.

SYSTEMIC AND LOCAL DELIVERY OF ANTIBIOTICS IN MANAGING PERIODONTAL DISEASES: AN UPDATE

The aim of this update was to evaluate the use of local and systemic antibiotics for the treatment of periodontal diseases. Due to the accumulation of bacteria in the form of dental plaque, the tissues and bone surrounding the teeth can become infected leading to periodontal diseases such as gingivitis and periodontitis. The main purpose of periodontal therapy is to eliminate or control the undesired effects of these bacteria present in the oral cavity in the form of biofilms. The use of antibiotics in conjunction with mechanical instrumentation has been suggested for the successful treatment of periodontal diseases. PubMed and google scholar databases were used to search through the past 30 years of literature using selected search criteria “Periodontal diseases*[TW] AND (gingivitis*[TW] OR periodontitis*[TW] OR antibiotics*[TW])” to identify articles/book chapters discussing polymerization shrinkage and possible solutions. In total, 46 articles/book chapters met the criteria for inclusion in the literature review. It can be concluded that the use of antibiotics is justified in cases with rapid signs and symptoms of destruction of periodontal tissues. Hence, antibiotics are suggested in cases of aggressive periodontitis, periodontal abscess, necrotizing ulcerative gingivitis, necrotizing ulcerative periodontitis and periodontitis that do not respond well to mechanical instrumentation alone. However, antibiotics may cause side effects and the bacteria may develop resistance, therefore dentists should keep in mind the adverse effects and benefits while prescribing antibiotics. Moreover, antibiotics should always be given as an adjunct to mechanical instrumentation and oral hygiene instructions to achieve successful outcome.

Oral Management of a Haematopoietic Stem Cell Transplant Recipient with Chédiak–Higashi Syndrome

Chédiak–Higashi syndrome (CHS), a rare autosomal recessive disorder associated with leukocyte dysfunction, is characterised by partial skin and hair albinism, immunodeficiency, and abnormal bleeding. Furthermore, it may be associated with cognitive and neurological impairments. The long-term prognosis of patients is generally poor, and haematopoietic stem cell transplantation is a radical immunodeficiency treatment. Here, we report a case of successful oral management of an 18-year-old woman with CHS accompanied by aggressive periodontitis who underwent haematopoietic stem cell transplantation.
