Some Investigations on the Surface Properties of Human Exposed Cementum (Part 3)
This study was designed to investigate multisided scaling of exposed cementum (group S), scaling followed by application of citric acid to exposed cementum (group S+C), root planing of exposed cementum (group R) and root planing followed by application to citric acid of exposed cementum (group R+C)....

Summary: | This study was designed to investigate multisided scaling of exposed cementum (group S), scaling followed by application of citric acid to exposed cementum (group S+C), root planing of exposed cementum (group R) and root planing followed by application to citric acid of exposed cementum (group R+C). The results were as follows: 1. The X-ray microanalyzer values for Ca, P and Ca/P were highest in group S and lowest in group R+S. 2. Scanning electron microscope examination revealed distinct striae with the curette-type scaler in group S, and that the striae tended to be weak in group R+C. 3. The relative concentrations of the target elements Ca, P and O/P were lower in group S+C than in group S and lower in group R+C than in group R, but Ca/P valves were similar in each of the groups based on X-ray photoelectron spectroscopy. Ca, P and F binding energies of the cementum were similar in each group. 4. The contact angles in group S and in group R were similar in intact cementum, but in groups treated with citric acid it was impossible to measure because of the extremely hydrophilic sol. |
