Tooth loss in periodontitis patients is associated with patient and site factors as well as with treatment provided. Not much is known about long-term tooth loss in periodontitis patients in private practice in the UK. The study plans to follow-up 200 subjects with periodontitis (and currently on maintenance therapy) for 5 years. The effect of treatment provided, site and patient risk factors on tooth loss will be studied.
