Sir, we read with interest the opinion of Dr van Steenberghe (BDJ 2005; 198: 187) regarding Mike Grace's leader (BDJ 2004; 197: 111) about a BDA survey question on periodontology in the UK.

As an academic, Dr van Steenberghe will doubtless be aware that the survey response rate of 19% (to which Dr Grace drew attention) would render any scientific study unpublishable. An acceptable rate from which to draw inferences would be around 80% or upwards. Dr Grace was simply using the findings as a literary device to make a point about a subject dear to his heart.

Dr van Steenberghe can rest assured that there is hope for periodontology in the UK, which is one of few countries with a list of nationally recognised specialists. Implant treatment planning and surgery are a routine part of UK periodontal practice, and although we also have recognised specialists in oral medicine, periodontists may diagnose and treat gingival conditions which might come under this heading.

As consultants in the largest UK periodontal department, we find an exceptional level of interest in our undergraduates, particularly in the fourth year when they have their major exposure to the subject. Our postgraduate courses are renowned in many countries, and we also started the first UK full specialist training course in the subject. Foreign governments frequently want their specialists trained here, but regrettably we have to turn away many promising postgraduate applicants each year because of a lack of space. Other UK periodontal departments report similar experiences. In short, the interest in the subject is considerable.

Furthermore, the British Society of Periodontology (BSP) is more active than it has ever been, and many well-attended events are arranged around the UK each year, in addition to the spring and autumn meetings.
