【Instructions】

1. Clean the tooth surface: install a small brush on the low-speed mobile phone, thoroughly clean the pits and grooves on the tooth surface that are to be sealed, and then rinse fully with a water gun. After cleaning the tooth surface, use cotton gauze balls to prevent moisture, dry the tooth surface and keep it dry.
2. Acid etching, rinsing and drying: It is recommended to use phosphoric acid gel with a phosphoric acid content of not less than 35% for acid etching. The etching time of permanent teeth is generally 20-30 seconds, and that of deciduous teeth is 60 seconds. Be careful not to wipe the etched tooth surface during the etching process, because this will damage the etched enamel surface and reduce the bonding force.
3. Apply sealant: Unscrew the sealing cap of the pit and fissure sealant, install a dental flushing needle or a dental delivery head, gently push the push rod of the conveyor, and directly apply the pit and fissure sealant to the pit and fissure. When applying pit and fissure sealant, attention should be paid to the discharge of air bubbles, and the coverage of the sealant should be smaller than that of the acid-etched surface, and it should be as thick as possible without affecting the occlusion. Sometimes it may be high, but it can be worn off after 2-3 days. If the coating is too thin, it will lack sufficient compressive strength and be easily crushed.
4. Curing: After coating, irradiate the pit and fissure sealant with a light curing machine (lamp) for 20-40 s. The wavelength of the light curing machine (lamp) should cover 420-480 nm, and the irradiance (light intensity) should not Less than 1000 mw/cm2, those with large area should be irradiated in stages. This product does not flow after curing, and forms a thin, hard milky white film on the tooth surface, which is easy to observe.
5. Inspection: After the sealant is cured, conduct a comprehensive inspection with a probe. Check for degree of cure, adhesion, presence of air bubbles, look for missing or unsealed fissures and reseal. Observe whether there is too much sealing material and whether it needs to be removed. If any problem is found, it should be dealt with in time; check the occlusal relationship, and adjust the grinding if the sealing agent is too thick.

History:

In the past, several attempts were made to protect pits and fissures from becoming carious; approaches, such as enamel fissure eradication, were used. This involved the widening of the fissures, or so-called fissurotomy, to transform deep fissures into cleansable ones Another method was to treat pits and fissures with ammoniacal silver nitrate [13]. None of these approaches, however, had a great measure of success. A more invasive approach was introduced by Hyatt in 1923 and this involved the preparation of a class I cavity that included all deep pits and fissures and the placement of a prophylactic restoration. In fact, this approach remained the treatment of choice until the 1970s [14]. In 1955, Buonocore published his classic study, documenting the method of bonding of acrylic resin to previously etched dental enamel. He described the technique of acid etching, using 85% phosphoric acid for 30 s, as a tool to increase the adhesion of self-curing methyl methacrylate resin materials to dental enamel. This study was indeed the beginning of a revolution in dental clinical practice [15]. In the mid-1960s, Cueto generated the first sealant material, methyl cyanoacrylate, but it was not marketed. This material, however, was prone to bacterial disintegration in the oral cavity over time [16]. Later on, Bowen invented a viscous resin, called bisphenol-a-glycidyl dimethacrylate, and this has become known as BIS-GMA [17]. This class was found to be resistant to degradation and successfully produced a bond with etched enamel. Buonocore made further advances and published his first paper about pit and fissure sealant, describing his successful use of BIS-GMA resin with the use of ultraviolet light in 1970 [18].
