Abstract:
OBJECTIVETo observe root surfaces and analyze the mineral contents in cementum of patients with rapidly progressive periodontitis (RPP).
METHODSTen teeth were selected from RPP patients, adult periodontitis (AP) patients and healthy (H) control subjects respectively, and prepared for scanning electron microscopy (JSM-35C). The energy-dispersive X-ray analysis was used to measure the mineral contents in cementum (Ca, P, Mg).
RESULTSThe root surfaces of RPP teeth were similar to that of AP teeth. Ca: 64.60% +/- 2.29% vs 63.54% +/- 2.97%, P > 0.05; P: 32.54% +/- 1.29% vs 32.97% +/- 2.40%, P > 0.05; Mg: 2.86% +/- 1.29% vs 3.48% +/- 1.02%, P > 0.05; Ca/P: 2.00 +/- 0.17 vs 1.95 +/- 0.25, P > 0.05. There were no differences in Ca, P, Mg contents and Ca/P ratio between RPP teeth and AP teeth.
CONCLUSIONThere may not be cementoplasia in a part of RPP teeth.
