Pit and fissure tooth surface treatment technology - Health - Dental Care

Pit and fissure caries is the key to improving sealant retention. Sealant retention under closed tooth surface material properties and the impact of processing technology, strong bonding with the enamel pit and fissure sealant is closed for good edge retention and the foundation. Dental sealant surface treatment technology is the key to whether you can keep a long time. Including tooth surface clean technologies and the application of fluoride, fissure enamel before acid etching and air abrasion polishing angioplasty surgery, before the laser etching, bonding technology and the tooth surface etching technology. Fissure tooth surface cleaning can remove plaque and food debris inside, so that etching agents and sealants can effectively and within the fissure enamel surface contact, help sealant retention. Clean tooth surface preparation fluoride sealant did not reduce shear strength, cleaning agents and fluorine can strengthen teeth tooth surface, acid resistance. Fissure en amel etching before the angioplasty will help the flow of sealant and sealant into the fissure, which can effectively improve sealer penetration and close together. Air abrasion polishing etching technique can be overcome in the treatment of anterior surface mechanical preparation arising from the pain, vibration, beep, and it can reduce the unnecessary loss of healthy tooth structure, no pain to complete the groove quickly cleaning preparation and shallow caries removal.

Laser treatment fissure advantages: expanded fissure entrance, changing the fissure forms, is conducive to the removal of residue inside the fissure, and help sealant into the fissure, so that the fissure sealant within the bulky , abrasion resistance is better; Compared with mechanical fissure preparation of tooth damage to normal tissue is small, and the laser treatment does not produce machinery ready for the children the fear; enamel and dentin after laser irradiation exposed surface active groups, composite resin can be produced with chemical bonding. Recently, because of hydrophilic binder in the pit and fissure sealant application, the sealant may be in a dry tooth surface is not completely get retention. Etching the tooth surface is an important part of treatment, etching techniques retention of pit and fissure sealant can be improved, the most commonly used clinical etching agents (37% phosphoric acid preparations) have two kinds of gel and solution dosage form s . The two formulations after etching the tooth surface sealant bond strength and clinical survival rate of very. Currently, acid-free washing agent is recommended, it can not handle the tooth surface with water, do not have to replace the lap, to save time. Tests showed that in terms of bond strength or the edge of the closed, non-flush etching bonding agent with phosphoric acid etching effect of homogeneous effect similar to, but when used in pit and fissure sealant, the result is not the same. That in the pit and fissure sealant use self-etching technology, as effective as traditional acid etch bonding technique, it is proposed should be used cautiously in clinical acid-free washing agent. However, in the same state of self-etching enamel with traditional etching bonding agent on the adhesion of fissure no significant differences.

Application of self-etching adhesives, pit and fissure sealant and enamel bond strength to exceed the traditional etching, resulting in significant, and, through self-etching adhesive for sealant evaluation of clinical efficacy, The results show that self-etching adhesive for sealant application system, can reduce clinical practice time and improve sealant retention rates, lower expulsion rate.
