What Is Early Teething?

Tooth cavity is closed by using a material (synthetic organic polymer resin that is harmless to the human body and can self-coagulate). It is coated on the surface of the tooth. When it is liquid, it can penetrate into the cavity of the tooth surface and solidify after light . It's like putting a protective coat on your teeth to protect them from food.

Dental sulcus closed

1, in general, deep fossa, especially the probe can be stuck (including suspicious caries);

2, the other teeth of the patient, especially the contralateral teeth of the same name who have caries or have a tendency to have caries should be closed;

3. After the teeth have emerged, the occlusal plane is suitable for sealing the pits and grooves, usually within 4 years of eruption.

4. The best time to close is: the primary molars are 3-4 years old, the first permanent molars are 6-7 years old, the second permanent molars are 11-13 years old, and the bicuspid teeth 9-9 years old. For disabled children with poor oral hygiene, although they are older or have teeth germinating for a long time, consideration may be given to relaxing the age at which the furrows are closed.

1. If the closed tooth is found to have a high bite or pain during eating within a few days after surgery, please consult again in time.

2. After the sealing material is found to fall off or partly fall off, please return to the clinic.

3, review every 6 months or 12 months after surgery in order to find problems and deal with them in a timely manner.

The ideal sulcus closure surgery should be done 4 times, that is, once at the age of three or four, the first permanent molars should be done once at the age of 6 years old, the bicuspids should be done at the ages of 9-13, and the second at 11-13 Permanent molars (bicuspid and second permanent molars can be done at the same time). The pit and fissure closure technique is divided into six steps, which are:

1. Clean tooth surface 2. Acid etching 3. Rinse and dry 4. Apply sealant 5. Cure 6. Check.

Here's how to do it in detail:

1. Clean the tooth surface:

Install a small conical brush or rubber cup on a low-speed mobile phone. Dip an appropriate amount of detergent on the tooth surface and scrub the tooth surface and the furrows back and forth for about 1 minute, while continuously dripping water to keep the brush moist. Dry brushes can also be used without detergent. Rinse mouthwash after brushing the tooth surface, and then use a sharp probe to clear the remaining detergent in the pits. Cleaners must not contain grease or excessively fine abrasives. Pumice powder or fluoride-free toothpaste can be used.

2. Acid etching:

After cleaning the tooth surface, a cotton yarn ball is usually used to easily dampen it. After the tooth surface is blown dry with compressed air, a small cotton ball or a fine-bristled brush is dipped in the acid etching agent and placed on the tooth surface to be closed. The acid etching agent may be a phosphoric acid solution or a gel containing phosphoric acid, and it is generally considered that the gel is better for keeping the acid etching area fixed at a certain position. The area of acid etching should be the range to be closed, which is generally 2/3 of the slope of the tooth tip. The etching time is 20-30 seconds for transverse teeth and 60 seconds for deciduous teeth. During the acid etching process, the acid etching agent should be added at any time, and it should be gently stirred to ensure that the acid etching agent has sufficient effect on the teeth, but it should be noted that the acid etching agent should not be brought into contact with the oral mucosa and soft tissues. During acid etching, do not wipe the tooth surface to avoid reducing the effect of acid etching.

3. Rinse and dry:

After acid etching, the tooth surface is thoroughly washed with water for 10-15 seconds to remove the enamel surface and the reaction sediment. If the gel containing phosphoric acid is etched, the rinsing time is doubled. The saliva should be cleaned at any time by using a saliva suction device while rinsing. Replace the moisture-proof cotton rolls immediately after rinsing. Do not let the sick vomit or gargle. Then use compressed air to dry the tooth surface for about 15 seconds, or use a volatile solvent to assist drying, such as: absolute alcohol, ether, etc.

5. Coating sealant:

Dip an appropriate amount of sealant with a brush to coat the tooth surface after acid etching. Pay attention to gradually coating from the far to the meridian along the furrow, and at the same time, brush the pen slightly and shake slightly, so that the sealant penetrates into the furrow, eliminates the air in the furrow, and prevents gaps under the furrow. The coating range should cover all acid-etched surfaces. Apply as much thickness as possible without affecting the bite. If the coating is too thin, it will lack sufficient compressive strength and be easily crushed.

6, curing:

Self-setting adhesive can be cured by itself within 1-2 minutes. Immediately after the light-curing blocking agent is applied, it is irradiated with a visible light source to initiate curing. The irradiation distance is about 1mm from the tooth tip, and the irradiation time is usually 20-40 seconds. The specific irradiation time depends on the performance of the visible light source and the type of sealing material used. The range of irradiation should be larger than the range of blocking agent coating.

7, check:

After the sealant is cured, perform a comprehensive inspection with a sharp probe, observe the degree of curing, the adhesion to the tooth surface, confirm the presence of air bubbles, look for missing or unclosed pits and reclose, and check whether the occlusion is too high If the problem is found, deal with it in time. If the sealer has no filler, the occlusal height may not be adjusted and can be ground off after 2-3 days; if a sealant containing a filler is used, the occlusion should be adjusted. After the closure, it should be reviewed regularly (3 months, half a year or one year) to observe the retention of the sealant. If it falls off, it should be re-closed.

1. If the closed teeth are found to have a high bite or feel uncomfortable and painful during eating within a few days after the sulcus is closed, you should consult the doctor promptly and let the doctor run in.

2. If some materials fall off or all fall off after the trench is closed, you should also ask your doctor to do it again.

3. Even if there are no adverse reactions after the sulcus is closed, it should be reviewed every 6 months or 12 months in order to find problems and deal with them in a timely manner.
