1 WHAT IS PERIODONTITIS?
Periodontitis is inflammation of the supporting tissues of the teeth (The Periodontium).
It can be divided into GINGIVITIS; inflammation and bleeding of the gums and PERIODONTITIS; inflammation and bleeding of the gums, together with destruction of the fibres and bone that hold the teeth in position in the jaws.
2 IS IT COMMON?
Information based on the most recent national oral health survey show, only 18% of 16–24 year olds, 8% of 35–44 year olds and 7% of older people aged 65 years and over have healthy gums.
3 WHAT IS THE CAUSE?
Perdiodontal disease is caused by plaque collecting on the teeth. Plaque is an accumulation of food debris, bacteria and other substances that forms on the teeth. This irritates the gums and makes them bleed. In certain people – about 1 person in 10, the plaque also causes the destruction seen in periodontitis. We do not know why people’s gums respond differently to plaque. However we do know that smoking reduces the ability of the gums to protect themselves from plaque.
4 IS PERIODONTAL DISEASE CURABLE?
A cure means to restore things to the state they were before the disease occurred. Gingivitis is curable, but periodontitis is not. However periodontitis can be arrested, and can be maintained, without any further destruction occurring.
5 HOW IS PERIODONTAL DISEASE TREATED?
Gingivitis and mild Periodontitis will resolve with a thorough professional cleaning, and with the patient cleaning their teeth as shown to them by the dentist. Moderate to severe Periodontitis is more complex.
TREATMENT OF PERIODONTITIS INVOLVES
(a) ASSESSMENT: This includes x-rays and measurements around the teeth. This is to determine the severity of the disease and to establish a baseline against which to measure progress.
(b) INITIAL THERAPY: This is divided into 2 phases:
1) WHAT THE DENTIST DOES: The teeth are root planed i.e.: cleaned very thoroughly under local anaesthetic. This is normally done in two or four appointments. – one quarter or one half of the mouth is cleaned at each appointment. Each session lasts up to 1 hour.
2) WHAT THE PATIENT DOES: The patient is instructed in how to clean plaque from the teeth. This involves brushing, flossing and Tepe brushes
THE PART OF THE PATIENT IS AT LEAST AS IMPORTANT AS THE PART OF THE DENTIST IN THE MANAGEMENT OF PERIODONTAL DISEASE.
REASSESSMENT: 6 weeks after initial therapy, the measurements around the teeth are repeated and compared with initial measurements. The patient’s oral hygiene is checked.
FOLLOW UP: For the first year after initial therapy, the patient is reviewed every 3 months to check on progress: by measuring around the gums, and assessment of plaque At the end of the year, the patient is reassessed in the light of the initial response to treatment, and the progress made in the following 12 months.
THERE ARE 3 POSSIBLE OUTCOMES.
- The disease has been controlled by Initial therapy, and the patient is maintaining good plaque control. This is the best outcome, provided the patient maintains good oral hygiene and goes for a regular check-up, the long term outlook is good.
- The disease was controlled initially, but the patient is not maintaining adequate plaque control. This is an unstable result, and will break down.
- The patient is maintaining adequate plaque control, but the disease was too severe to be controlled by root planning.The options here would be:
(a) Extract the teeth around which the disease is uncontrolled.
(b) Do periodontal surgery in the unstable sites. The probability of surgery being necessary is not high; about one patient in every 100 who needs initial therapy.
