What Is Non-Therapeutic Use?

Non-traumatic repair (ART) refers to the use of hand instruments to remove softened and completely demineralized dental caries, then fill the cavity with adhesive oral repair materials, and at the same time close the points that are prone to caries Crevices. Using glass ions as a repair material is a modern treatment method that prevents the progression of caries, with the greatest prevention and minimal trauma.

Non-traumatic repair (ART) refers to the use of hand instruments to remove softened and completely demineralized dental caries, then fill the cavity with adhesive oral repair materials, and at the same time close the points that are prone to caries Crevices. Using glass ions as a repair material is a barrier

This technology was recommended by the World Health Organization in 1994 and has been used in many countries. China is also conducting related research on ART clinical and laboratory. ART is very suitable for community oral health care and can be included in the scope of primary oral health care services. It is a filling method that is particularly worthy of promotion in some underdeveloped remote and rural areas.

1. It is suitable for small caries in permanent and deciduous teeth, and allows the smallest excavator to enter;

2. No pulp exposure, no suspicious pulpitis, etc.

1. Material: glass ion powder, liquid, dentin treatment agent.

2. Apparatus: There are mouth mirrors, tweezers, probes, mixing papers, digging spoons, tooth axe (or shaper), carving knife, etc. The success of treatment depends on the operator to master the role of various instruments And used correctly.

Dig spoon: remove soft caries, clean the cavity; generally divided into three, small diameter of 0.6mm, medium diameter of 1.5mm, large diameter of 2.0mm. Axe shaped device (or prong shaped device): extended cavity medical teaching | Yuwang collects and organizes to further expand the opening and make the excavator easy to enter.

Carving knife: It has two functions. The flat end is used to put the material into the filling hole, and the sharp end is used to remove the excess filling material and repair the shape of the tooth.

Resin strips and T-shaped strips: shaped pieces for restoring the shape of adjacent gaps of teeth, the former for permanent teeth and the latter for deciduous teeth. Wooden wedge: It is used to put resin strips on the adjacent surface to prevent the material from pressing into the gums. It is made of cork.

Hole preparation

Use a cotton roll to keep it dry and dry. Wipe the dental plaque with a wet cotton ball. Dry the surface with a dry cotton ball to determine the size of the caries. If the enamel opening is small, use a tooth to axe to enlarge the entrance. Some non-base enamel may be broken. Use a small wet cotton ball to remove the broken enamel, and then wipe it with a cotton ball when continuing the operation. The hole is large enough to be accessed by a digging spoon to remove soft carious tissue, which can make the carious cavity moist and facilitate the removal of carious tissue. After the initial removal of softened dentin, it may be necessary to expand the cavity entry. Remove soft caries. Special attention should be paid to the use of a digging spoon to rotate vertically around the edge of the hole to remove caries and reach the enamel dentin boundary. Dentin close to the pulp cavity should be retained to avoid pulp exposure. Place the removed caries on the cotton roll and clean the instrument. Use a cotton ball to keep the caries cavity dry and clean. The patient is asked to bite. Observe whether the tooth is in contact with the carious cavity, which will help to trim and adjust the occlusion after filling.

Polyhedral holes are prepared using the same principles as single-sided holes.

2. Clean

The cavity is cleaned with a treatment agent to promote chemical bonding between the glass ionomer material and the tooth surface. The treating agent is generally weak polyacrylic acid (10%). Dip a small cotton ball or small sponge ball into the entire cavity for 10 seconds, and rinse twice immediately. If the cavity is contaminated with blood and saliva, stop bleeding in a timely manner, rinse and dry, and then apply a treatment agent with a dry cotton roll.

3. Mixing and mixing

According to the powder-liquid ratio recommended by the manufacturer, place the powder on the mixing paper or mixing plate first, and divide it into two equal parts. A drop of liquid is dropped into the powder. Use a mixing knife to mix the powder with the liquid without spreading it everywhere. When half of the powder is wet, mix the other half. Mixing should be completed within 20-30 seconds, and then put the mixed material into the hole to be filled as soon as possible. Filling should be done before the material is dull. If the material has lost its luster and dried, it should be remixed. It cannot be filled with the dried material.

Note: Only open the packaging bottle and remove the powder and water solution when mixing. Tighten the cap of the powder bottle after use to prevent moisture, and immediately remove the material on the instrument or put it in water for a little Easy to clean after.

Each type of glass ion material has its own characteristics, please use according to the manufacturer's instructions.

(1) One-sided hole

Pay attention to keep the working environment dry, dry the caries hole with a cotton ball, mix the glass ions, put them into the prepared holes with the blunt end of a carving knife, and squeeze the glass ions with the convex surface of the scoop. Take care to avoid air bubbles. The filling material is slightly higher than the tooth surface, including filling the remaining gaps.

Before the filling material loses its luster. Put a gloved finger on a little vaseline and place it on the caries hole to squeeze the medical education | Yuwang.com collects and arranges so that the glass ions enter the caries hole, and then remove the finger when the material is no longer sticky (about 30 seconds) . Remove excess material with instruments, cover the filling material with vaseline, and keep the filling dry for 30 seconds. After filling, check the occlusion with occlusal paper. If the occlusion is high, remove excess material, adjust to normal occlusion, and then apply a layer of paint. Finally, let the patient rinse his mouth and tell him not to swallow for an hour.

(2) Compound face hole

The filling of the facet hole is basically the same as the facet hole operation. The facet hole is generally divided into anterior teeth and posterior teeth. The facet hole is usually carious and involves multiple teeth. Therefore, special care should be taken to ensure that the shape of the filling is normal.

1) Filling of anterior teeth

Use a cotton roll to keep the working environment dry; dry the caries with a cotton ball; correctly place the shaped sheet on the adjacent surface of the tooth so that the filling conforms to the designed adjacent surface shape; place the cork wedge between the gum edges to maintain the position of the shaped sheet ; Mix the glass ions according to the above method and slightly overfill; use your fingers to press the formed piece from the direction of the parallel tooth surface, and wrap it tightly around the lip surface to make the material enter the cavity, and press it with your thumb for about 30 seconds until the material Curing. The filler will now be close to its normal shape. Remove the formed piece, remove excess material with a carving knife, check for bite and apply a layer of petroleum jelly. Finally, ask the patient to rinse their mouths and tell them not to eat for an hour.

2) Cavity filling of posterior teeth

The posterior facet cavity is also filled with a shaped sheet to maintain its shape, and deciduous teeth do not always require complete restoration of the adjacent face shape. According to the size of the cavity and the teeth

It meets the key points of modern prevention, not only filling the caries, but also closing the gaps and fissures in the high-risk parts of caries. It does not require a power source, and uses simple and cheap hand instruments instead of expensive electric oral equipment. The equipment can be carried around, safe to operate, easy to learn, and cheap. The method for controlling cross-infection is simple, and does not require a high-pressure disinfection mobile phone, and hand instruments are easy to clean and disinfect after each use. It can also reduce the psychological trauma of patients, which is easy for patients to accept.

In short, using ART combines health education with the promotion of dental caries prevention and treatment and the relief of pain.
