Outcome Measures

Primary Outcomes (4)

  • Bacterial load of six main periodontal pathogens

    Bacterial load mean of six main periodontal pathogens expressed as number after a polymerase chain reaction count

    November 16th 2016

  • Prevalence of six main periodontal pathogens

    Number of sites presenting a specific pathogen

    November 16th 2016

  • Relative bacterial load of six main periodontal pathogens

    A mean percentage that derives from the comparison of the bacterial load to the total bacterial load

    November 16th 2016

  • Total bacterial load

    A mean of all bacteria present in a periodontal site expressed as number after a polymerase chain reaction count

    November 16th 2016

Secondary Outcomes (1)

  • Genotypes of Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The recruitment for the study sample was performed analysing the medical records of adult patients with chronic periodontitis visited between 2010 and 2016. Eligible patients were subdivided in two balanced groups on the basis of the presence or absence of type 2 diabetes mellitus at the time of the microbiological test.

You may qualify if:

  • diagnosis of chronic periodontitis
  • diagnosis of type 2 diabetes mellitus (only in the test group)
  • the presence of at least 12 teeth (except for the third molar)
  • belonging to caucasian ethnic group
  • age greater than 18 years.

You may not qualify if:

  • pregnant or lactating
  • history of systemic antibiotics within 3 months prior to the microbiological testing or anti-inflammatory therapy in the month before the visit
  • if they were suffering from any other systemic disease except diabetes mellitus (arthritis, ulcerative colitis, Crohn's disease, osteoporosis or osteopenia, HIV infection, hematologic diseases, neoplastic diseases, cardiovascular diseases or pathologies that could potentially interfere with the periodontitis and/or with diabetes)
  • mental disorders
  • if they had received periodontal treatment in the 6 months before the microbiological test.
