The association between Aggregatibacter actinomycetemcomitansJP2 clone and periodontitis: A systematic review and meta‐analysis

Journal of Periodontal Research, 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 ...

Natural Therapeutic Agents’ Efficacy in Preventive Strategies against the Periodontal Pathogen Aggregatibacter actinomycetemcomitans: An In Vitro Study

Oral
Adolescent carriers of the Aggregatibacter actinomycetemcomitans JP2 genotype have an increased risk of developing periodontitis, due to the bacterium’s high leukotoxin (LtxA) production.

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.

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.
