CHICAGO – November 21, 2001 – Patients who are at risk for losing teeth to periodontal disease show improved prognosis for keeping their teeth
following periodontal surgery, according to a study in the Journal of Periodontology.
The study evaluated the effects of no treatment, non-surgical therapy, and periodontal surgery on 2,350 teeth of patients who presented with moderate to severe periodontitis. Forty-eight percent of teeth receiving periodontal surgery improved prognosis, while only 12% of the teeth that received no treatment or that underwent non-surgical treatment improved. In addition, more than 35% of the teeth in the no treatment and non-surgical treatment groups actually worsened in prognosis.
"These findings are important for patients who value oral health and want to keep their teeth a lifetime," explained Stephen
Harrel emphasizes that these findings are significant compared to previous studies that used an overall average "score" for each patient (patient mean) instead of individual teeth to determine the impact of periodontal treatments and non-treatment. "The damage from periodontal disease is often localized, so the individual teeth that have damage should be followed in order to obtain a true picture of treatment results. Results based on patient means can mask positive or negative effects of treatment."
"This research can help save patients' smiles by illustrating tooth loss as a consequence of what happens when periodontal disease is ignored
and not fully treated," said
