Interproximal tooth coating applicator
The present invention relates to a tooth coating applicator ( 10 ), typically in the form of a strip ( 11 ), and a method for applying a dental sealant to a surface of a tooth (T), and specifically to the interproximal surface (S) thereof. The applicator ( 10 ) is elongated and is adapted to be typically inserted into an interproximal space (I) defined between a pair of adjacent teeth (T, T′) and to be gradually slid against a dental surface of one of the teeth. The applicator ( 10 ) comprises a series of substrates ( 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 36, 40, 42 ) for generally successively removing debris and deposits from the interproximal dental surface (S), etching ( 20 ) the dental surface (S), washing ( 22 ) the dental surface (S), drying ( 24, 26 ) the dental surface (S), carrying ( 28 ) the sealing agent and applying the sealing agent to the dental surface (S), exerting pressure ( 30 ) on the dental surface (S) during the hardening of the sealing agent, and polishing ( 36, 38 ) the dental surface (S) and its cured sealing agent.
1. A method for applying a sealing agent to an interproximal surface of a tooth, said method comprising:
a) providing an elongated strip comprising a substrate which is configured to substantially conform to a shape of the interproximal surface to be treated;
b) pre-forming said substrate substantially along the shape of the interproximal surface to be treated;
c) applying said sealing agent to the substrate after the substrate has been pre-formed in the previous step;
d) placing said pre-formed substrate and said sealing agent in contact with the interproximal surface; and
e) handling said substrate such that at least a part of said sealing agent is transferred onto the interproximal surface.
2. A method as defined in claim 1 , wherein in step e), said strip is slid along the interpromximal surface such that said sealing agent is applied onto the interproximal surface.
3. A method as defined in claim 1 , wherein during step e), the method comprises applying pressure on said sealing agent during hardening thereof on the interproximal surface.
