1. What PerioChip is and what it is used for

What is PerioChip

PerioChip is a small chip containing the antimicrobial agent chlorhexidine digluconate.

What is PerioChip for

Most people will at some stage of their lives suffer from gingivitis, which is inflammation of the gums. If gingivitis is left untreated, it may lead to periodontitis which can result in tooth loss. Periodontitis is a disease in which the tissues that support the teeth become inflamed and degenerate. This disease can be prevented by treating gingivitis in the early stages. If, however, gingivitis is not treated, the gums will be attacked by bacterial build-up known as plaque,causing the gum to become separated from the tooth and resulting in the formation of a periodontal pocket. Once a pocket has formed, plaque can build up and the disease can become worse.

PerioChip is inserted by a dentist into the periodontal pocket to eliminate most of the disease-causing bacteria, to reduce the pocket inflammation and to decrease the depth of the pocket.

PerioChip is used in combination with the mechanical removal of plaque in the treatment of chronic inflammatory periodontal disease in adults.

2. What you need to know before you use PerioChip

Do not use PerioChip if you are allergic (hypersensitive) to chlorhexidine gluconate or any of the other ingredients of PerioChip (see section 6).

Special warnings and precautions

PerioChip may in rare cases cause severe allergic reactions, leading to a drop in blood pressure and even to unconsciousness. Early symptoms of a severe allergic reaction may be skin rash or asthma. If you notice these symptoms, contact your dentist or doctor as soon as possible (see under section 4: “Possible side effects”).

Children and adolescents

PerioChip is not recommended for use in children and adolescents.

Other medicines and PerioChip

Tell your dentist if you are taking nystatin (for the treatment of fungal infections) as it may reduce the effectiveness of PerioChip.

Please tell your dentist if you are taking, have recently taken or might take any other medicines including medicines obtained without prescription, although it is unlikely that any problems will arise if you take any other medicines.

Pregnancy and breast-feeding

You should inform your dentist if you are pregnant or breast-feeding. Your dentist will decide whether you should receive this treatment.

3. How to use PerioChip

After cleaning your teeth mechanically to remove as much plaque as possible, your dentist will put PerioChips into all those tooth pockets, which need to be treated. The chips will then dissolve slowly over about 7 days and do not need to be removed.

Your dentist may ask you to return within about three months to check how your treatment is working and perhaps to continue your treatment with more PerioChips.

Your dentist will advise you if any other medication is needed while you are receiving treatment with PerioChip.

You should continue to clean your teeth as normal. No change in your diet is necessary while being treated with PerioChip.

4. Possible side effects

Like all medicines, PerioChip can cause side effects, although not everybody gets them.

If you experience any of the following reactions, get immediate medical help:

swelling e.g. of the face, lips, tongue or throat; skin rash; itch; wheezing or difficulty breathing; feeling faint and dizzy; rapid heart rate; upset stomach or diarrhoea. You may be having an allergic reaction.

During the first few days following PerioChip insertion, you may temporarily experience pain or discomfort of the gum and teeth and swelling and/or redness of the gums, this may be due to the scaling procedure or the physical placement of the chip.
