Антисептические средства в стоматологии

Antiseptic agents used in dentistry. Chlorhexidine VS Betadine

These are 2 drugs that are most often used in dentistry as antiseptics, and we will try to talk about each. And also, find out which drug is preferable.


So, chlorhexidine is an antiseptic that acts on microorganisms in the oral cavity (gram-positive and gram-negative bacteria). It has bacteriostatic, bactericidal, fungicidal, virucidal actions. And the most interesting - the drug is stable when treating the skin (hands, mucous membranes). Active in blood operations, pus and organic matter. Practically does not cause allergic reactions, does not irritate the skin and mucous membranes.

Of the minuses - it can stain teeth in brown, which is very poorly removed by a toothbrush.

Indications for the use of chlorhexidine

Antiseptic treatment and disinfection. 0.05 and 0.2% solutions: disinfection of the mucous membrane and skin.

Purulent wounds, stomatitis, bacterial and fungal diseases of the mucous membranes, gingivitis, aphthae, periodontitis, alveolitis.

  • 0.2% solution: for the treatment and disinfection of removable dentures
  • 0.5% solution: for the treatment of wounds and burns in the oral cavity
  • 1% solution: disinfection of work surfaces and medical equipment, medical devices that are undesirable to be thermally treated (or impossible), treatment of the surgeon's hands before surgery, treatment of postoperative wounds
  • 5% concentrate: for the preparation of various aqueous, glycerin and alcohol solutions with concentrations from 0.01 to 1%.

Contraindications. Sensitivity to the drug, childhood, pregnancy, lactation.

Side effects. Staining of tooth enamel, deposition of tartar, taste disturbance. Concomitant use with iodine is not recommended.


Betadine is interesting in that it has antiseptic properties with a broad antimicrobial effect, as well as of some fungi and viruses. It exhibits antifungal, antiviral, antiprotozoal activity. It acts longer than inorganic iodine preparations. The action continues until the colored field disappears completely from the application surface. The intensity of staining of this field - this is an indicator of the effectiveness of the drug. When it enters the mucosa, it is gradually absorbed and has an antimicrobial effect.

Indications. Basically, a 10% solution is used in surgical dentistry, wound infections, in the preparation of the surgical field; treating the patient’s skin and mucous membranes before surgery, treating wound infections.

Application. The solution is applied in diluted and undiluted form. Dilution of betadine is carried out immediately before use. Apply no more than 2-3 times a day.

Overdose. When swallowing betadine, the symptoms are the same as when swallowing iodine: abdominal pain, itching in the oral cavity.

Side effects. If itching, swelling, stop using the drug.

Contraindications. Allergic to iodine - do not take or use the drug.

How betadine behaves with other drugs. This drug should not be used in combination with drugs that include mercury or benzoic tincture.

Chlorhexidine VS Betadine

From our practice, we can say that these are completely different antiseptics that are used in different branches of dentistry.

Betadine is more often used in surgery and so far there are no analogues to this composition. When using this drug, we forgot about the complications that are possible with surgical interventions. Of the minuses - an allergic reaction to iodine-containing drugs.

Chlorhexidine is often used in therapeutic dentistry, in the treatment of periodontitis, but you should remember about staining your teeth. Although the suppliers of this drug claim that there is a different concentration of chlorhexidine in the solution in order to exclude staining of the teeth, but nevertheless, we have the opposite. Also, chlorhexidine is not used in surgery, especially where APRF is used, since chlorhexedine deactivates the APRF clot.

We use only proven drugs and when receiving dental services from us, you can be calm for your health.
