Protein HtpG Linked to Disease-Free Teeth and Gums
According to researchers, antibodies present in people with good oral health could become the first tool for dental professionals to assess a patients probable response to periodontal disease treatments.
The antibody is a protein called HtpG, the bug that makes it is Porphyromonas gingivalis, an important pathogen in periodontal disease.
According to Charles Shelburne, assistant research scientist at the U-M School of Dentistry, the antibody also has potential as a vaccine candidate.
During the study, researchers discovered that the HtpG antibodies were present in much lower amounts in people with periodontal disease, and in much higher concentrations in those with healthier teeth and gums.
Usually, antibodies are elevated in people with disease, because they help fight the disease.
"What has been seen in periodontal disease over the last 30-40 years is that patients with periodontal disease have higher levels of antibodies to the bacteria associated with periodontal disease, but what we know is that those antibodies arent usually protective," said Dennis Lopatin, principal investigator and senior associate dean of the School of Dentistry.
"Its like being vaccinated against the wrong strain of the flu. The healthy patient makes high levels of the antibodies but to the right part of the bug," he added.
Researchers said that not only were the HtpG antibodies present in higher amounts in people with healthier gums, those patients with the antibodies responded better to periodontal treatment.
