Periodontal microbiology and microbial etiology of periodontal diseases: Historical concepts and contemporary perspectives

Periodontology 2000, EarlyView., 2023
Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

The association between Aggregatibacter actinomycetemcomitans JP2 clone and periodontitis: A systematic review and meta‐analysis

Journal of Periodontal Research, Volume 58, Issue 3, Page 465-482, June 2023., 2023
Abstract To appraise the literature on the prevalence of the JP2 clone of Aggregatibacter actinomycetemcomitans (A.a.) and on its association with presence and progression of periodontitis in different populations. A systematic search of the literature was conducted in Medline, Embase and Cochrane Library for studies reporting data on detection of the ...

Radiographic and clinical signs of periodontitis and associated bacterial species in a Swedish adolescent population

Journal of Periodontology, Volume 94, Issue 5, Page 630-640, May 2023., 2023
Abstract Background Periodontitis in adolescents has historically been rare in the Nordic countries but could be expected to increase due to changing demographics. The primary aim was to cross‐sectionally examine the presence of radiographic bone loss in adolescents in Västerbotten County, Sweden.

Additional benefit of systemic antibiotics in subgingival instrumentation of stage III and IV periodontitis with Aggregatibacter actinomycetemcomitans: A retrospective analysis

Journal of Clinical Periodontology, Volume 50, Issue 5, Page 684-693, May 2023., 2023
Abstract Aim To evaluate subgingival instrumentation (SI) in periodontitis stage III and IV, grade B and C with systemic antibiotics (AB) only after detection of Aggregatibacter actinomycetemcomitans. Materials and Methods Patients of the Department of Periodontology of Goethe University Frankfurt/Germany were screened for microbiological testing ...

Molecular epidemiology of the citrus bacterial pathogen Xanthomonas citri pv. citri from the Arabian Peninsula reveals a complex structure of specialist and generalist strains

Evolutionary Applications, Volume 15, Issue 9, Page 1423-1435, September 2022., 2022
Abstract Molecular epidemiology studies are essential to refine our understanding of migrations of phytopathogenic bacteria, the major determining factor in their emergence, and to understand the factors that shape their population structure. Microsatellite and minisatellite typing are useful techniques for deciphering the population structure of ...

A comparative study on periodontitis and periodontitis‐associated bacteria in Somali and non‐Somali children and adolescents living in Trollhättan, Sweden

European Journal of Oral Sciences, Volume 130, Issue 2, April 2022., 2022
Abstract The reported prevalence of periodontitis in children and adolescents varies considerably between populations globally. This cross‐sectional study compares clinical and microbiological findings on 83 Somali immigrants and 96 non‐Somali children aged 10–17 years old living in Trollhättan, Sweden. The clinical examination included registration of

An in vitro model for studies of attenuation of antibiotic‐inhibited growth of Aggregatibacter actinomycetemcomitans Y4 by polyamines

Molecular Oral Microbiology, Volume 36, Issue 6, Page 308-315, December 2021., 2021
Abstract Polyamines are ubiquitous polycationic molecules that are present in all prokaryotic and eukaryotic cells, and they serve as important modulators of cell growth, stress, and cell proliferation. Polyamines are present at high concentrations in the periodontal pocket and could potentially affect the stress response of periodontal bacteria to ...
