Effect of an air‐powder abrasive system on root surfaces in periodontal surgery

Abstract

The purpose of this study was to compare the effectiveness of an air-powder abrasive technique to conventional root planing during periodontal surgery. 7 patients scheduled for multiple extractions of periodontally-involved teeth were selected. Full thickness mucoperiosteal flaps were reflected, and proximal surfaces of 32 teeth were either ultrasonically scaled and exposed to the air-powder abrasive, or ultrasonically scaled and then manually root planed. Following extraction, teeth were stained for residual plaque and photographed, or prepared for scanning electron microscopy. The air-powder abrasive technique used for surgical root preparation was found to produce a root surface favorably comparable to manual root planing with regard to removal of plaque, calculus, and exposed cementum. A mean of 80 micron of cementum was abraded away after 40 s of exposure to the air-powder spray. The air-powder abrasive spray demonstrated an advantageous ability to remove plaque and cementum from areas of difficult access, such as furcations and root flutings.

A Comperative Evaluation of 3 Different Polishing Methods on Tooth Surface Roughness

“…In our study, while it was observed a smooth appearance on half of the tooth in group applied air-flow and polishing in average, the surface roughness increased in the other half, in line with the other studies showing the harmful effects of air-polishing systems [21,23,[27][28][29]. Although polishing applications were only limited to the enamel surface in our study, this result emerged showed that air-polishing could lead to the opposite results with the philosophy of polishing application, even though it was applied on the enamel surface.…”

“…In many study, it was shown that air-polishing devices became time-saving and effective in the application on normal enamel surface [19][20][21][22][23]. However, it does not generally lead to surface modification and loss of materials to be able to be detected clinically [23,24].…”

Subgingival Plaque Removal at Interdental Sites Using a Low‐Abrasive Air Polishing Powder

“…This damage becomes clinically relevant when APDs are repeatedly used during PMT due to its cumulative effects. [12][13][14][15][16][17][18][19][20][21][22][23][24] To minimize this problem, a novel low-abrasive air polishing powder § which allows efficient plaque removal on root cementum or dentin without root damage in vitro 25 has been developed. Since the low-abrasive powder consists of biocompatible organic salt crystals which slowly dissolve in water, it may be used for subgingival plaque removal in PMT.…”

Comparison of two methods of dental prophylaxis: evaluation of arterial pressure and patient comfort in a clinical randomized controlled trial

“…To Saad et al 29 the Robson rubber cup/brush acts more on the surface, while the bicarbonate jet technique would have more action in depth because it uses jets under controlled pressure, which are better for pit and fissure regions. Accordingly, Horning et al 8 found that the jet of sodium bicarbonate has an advantageous ability to remove plaque from hard to reach areas, such as furcations and deep grooves.…”

“…It has been used successfully in the removal of non-mineral stains caused by smoking, has been implemented indifferent components of dental implants and has been used safely in the cleaning of supragingival orthodontic devices 4,5 . However, it should be used with caution in areas of demineralized enamel because erosion of enamel prisms 6 may occur, resulting in the exposure of root surface dentin or significant substance removal 2,[7][8][9] , which is of particular interest in periodontal maintenance therapy because gingival recession is a common finding in postperiodontal treatment patients 10,11 . Sodium bicarbonate can so lead to substantial erosion or blunting of restorative materials, with the exception of ceramics, which seem to experience a less significant loss of substance 9,[12][13][14] .…”
