Embodiment 1

[0082] Air polishing compositions having the compositions listed in Table 1 below were prepared.

[0083] Table 1

[0084] formula ％ sodium bicarbonate 81.50 Aerosil R972 4.00 sodium saccharin 2.00 sodium fluoride 0.50 potassium nitrate 2.50 Calcium nitrate tetrahydrate 2.00 Sodium hydrogen phosphate dodecahydrate 2.5 Poloxamer 5.00

[0085] The compositions were prepared in the following manner.

[0086] A first premix A was prepared by adding half the amount of sodium bicarbonate and half the amount of Aerosil R972 to a mixture comprising calcium nitrate tetrahydrate and disodium hydrogen phosphate dodecahydrate. The mixture was homogenized using a cube mixer sold under the trademark Frogerais. The mixture was then sieved at 200 μm using a vibrating sieve.

[0087] A second premix B was prepared by mixing the other half of the amount of sodium bicarbonate, the other half of the amount of Aerosil R972, sodium s...

Embodiment 2

[0093] Air polishing compositions were prepared having the formulations listed in Table 2 below.

[0094] Table 2

[0095] formula ％ calcium carbonate 20.00 Silicone R972 1.00 sodium saccharin 1.00 Chlorhexidine hydrochloride 2.50 potassium nitrate 2.50 tricalcium phosphate 17.00 carrageenan 56.00

[0096]The compositions listed in the above Table 2 were obtained by sequentially adding the following substances to calcium carbonate: sodium saccharin, chlorhexidine hydrochloride, potassium nitrate, tricalcium phosphate, carrageenan gelling agent and Aerosil R972.

[0097] The mixture was then homogenized using a mixer of the bin agitator type sold by the supplier Servolift. The resulting composition was then sieved with a vibrating sieve.

[0098] The composition obtained had an average particle size in the range of 40 μm to 60 μm when measured using a laser particle sizer of the type “Mastersizer 2000” sold by the suppl...

Embodiment 3

[0101] Air polishing compositions were prepared having the formulations listed in Table 3 below.

[0102] table 3

[0103] formula ％ Glycine 60.00 Silicone R972 2.00 sodium saccharin 2.00 mint flavoring 0.50 Lidocaine 2.50 Hydroxyapatite 18.00 Methocel E4M 15.00

[0104] The composition was prepared by grinding glycine with a hammer mill sold by the supplier Poitemill Forplex. The following were then added sequentially to the ground glycine: sodium saccharin, peppermint essential oil, lidocaine hydrochloride, hydroxyapatite, Methocel E4M and Aerosil R972. The composition is homogenized using a V-blender sold by the supplier Olsa and then sieved with a vibrating sieve at 300 μm.

[0105] The average particle size of the resulting composition is in the range 15 μm to 35 μm, measured with a laser particle size analyzer of the type “Mastersizer 2000” sold by the supplier Malvern.

[0106] The composition prepared in this ...

Abstract

The present invention particularly relates to a composition for air-polishing the surface of dental hard tissue, said composition comprising at least: - a first powder of an abrasive capable of polishing dental hard tissue; - a second powder of a gelling agent; And - a third powder of dental treatment.

Description

technical field [0001] The invention relates to a novel composition for air polishing the surface of dental hard tissue and its use in the air polishing method. Background technique [0002] Powders for dental air polishing are usually based on glycine, calcium carbonate or sodium bicarbonate. Known powders include notably a glycine-based powder developed by the supplier 3M ESPE and available for subgingival use under the name "Clinpro TM Prophy Powder", and for supragingival use by the supplier Satelec under the name "Air-n-go "Sold sodium bicarbonate-based powder. [0003] However, there is a need to improve existing air polishing processes in order to further functionalize such processes without the resulting significant increase in process time. [0004] In particular there is a need for available air polishing treatments with improvements which also enable an effective therapeutic action on the treated teeth without resulting in a significant prolongation of the tre...
