Effect of air-powder abrasive instrument on restorative materials

Dentine caries excavation: a review of current clinical techniques

“…35 However, due to the non-selective, abrasive, detrimental surface attack of restorations and sound enamel and dentine, overzealous use could easily remove a considerable amount of healthy tooth structure especially at the cervical margin. 40,41 It has been suggested that air-polishing could be used for the removal of carious dentine at the end of cavity preparation. 37 …”

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

“…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] . Still, there is epithelial erosion and exposure of underlying connective tissue in the soft tissues around the tooth 3,[15][16][17][18][19] .…”

Effects of an air-powder polishing system on orthodontically bracketed and banded teeth

“…2 Studies of the air-powder polishing method have examined its efficacy in stain removal 2 and its effects on soft tissue, 2,6-12 hard tissue, 5,13,14 and restorative materials. 3,15,16 William et al 15 found that air-powder polishing treatment imparted a nonuniformly roughened surface to enamel. Atkinson et al 5 and Toevs, 14 however, found root surfaces to be smooth after treatment with the airpowder polishing system.…”

“…17 Although air-powder polishing systems have been shown to be effective, it has been demonstrated that these systems have the potential for removing considerable amounts of resinous restorative material. 3,15,16 On the other hand, porcelain, amalgam, and gold alloy restorations generally are not significantly affected. 15,16 However, Barnes and associates did note an erosion of cement from the margin of cast-alloy restorations.…”

“…3,15,16 On the other hand, porcelain, amalgam, and gold alloy restorations generally are not significantly affected. 15,16 However, Barnes and associates did note an erosion of cement from the margin of cast-alloy restorations. 3 The purpose of this two-part study, based on studies to date that have shown deleterious effects on resinous materials and cement, was to examine the efficacy and effects of an air-powder polishing system on orthodontically bracketed and banded teeth.…”
