Radiographic alveolar bone morphology and progressive periodontitis.

Background: This study evaluated the relationship between radiographic crestal alveolar bone morphology and progressive periodontitis.

Methods: A total of 1,356 posterior interproximal sites in 56 adults treated for chronic periodontitis and receiving systematic 3-month maintenance care were scored for angular or horizontal marginal bone morphology, as well as for alveolar crestal lamina dura, on radiographs obtained at baseline of a 30-month post-treatment period. Semi-annually, the study patients were clinically evaluated for progressive periodontitis.

Rediscovering Sig Socransky, the genius and his legacy.

Some individuals make contributions so vital to their field of knowledge that their names become almost synonymous with that field. This is the case of Sig Socransky and the field of periodontal microbiology. Sig Socransky, or simply Sig, was born in Toronto, Canada and received his DDS degree from the University of Toronto in 1957.

Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis subgingival presence, species-specific serum immunoglobulin G antibody levels, and periodontitis disease recurrence.

Background And Objective: The biological and clinical effects of antibody against periodontal pathogenic bacteria are incompletely understood. This study evaluated the inter-relationships among periodontal levels of cultivable Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis, species-specific serum immunoglobulin G (IgG) antibody levels, and periodontitis disease activity.

Material And Methods: Forty-three adults who had previously been treated for periodontitis and who also harbored cultivable A.

Microbial identification in the management of periodontal diseases. A systematic review.

Background: Our understanding of the complexity of the oral microbiota continues to improve as new technologies, such as the analysis of 16S rRNA bacterial genes, are utilized. Despite the difficult of cataloguing all microorganisms and determining their pathogenic potential, some species, mostly members of the resident oral microbiota, have been identified as likely periodontal pathogens. However, for microbial diagnosis to be of value, it needs to affect disease diagnosis and/or treatment planning as well as result in superior treatment outcomes and/or provide an economic benefit to the patient.
