If you want to know more about Munro_Hall dentist take a look at the GDC hearing on the GDC website
http://www.gdc-uk.org/General+public/Fitness+to+Practise+hearings/

just an update on that case.If you go onto link,click on "recent hearings" then at the bottom click on page 2,
Graeme Robert Munro Hall, (3rd name from bottom)

Case was on 10th December 2007,
he was found NOT GUILTY
of serious professional conduct.

To cut a long story short he replaced amalgams for a patient
who had motor neuron disease.
The patient had been told he had mercury poisoning(by someone else)and asked Munro hall for the dental treatment.
Doctor contacted him with concerns about procedures,which Munro hall ignored and removed the amalgams of patient regardless of warning because that was what the patient really wanted.

For anyone here interested in more details of case
go to link above find Munro hall,and there are 3 sections:

1.Charge
2.Finding of facts
3.Determination

I thought these were interesting
no.19 "...the committee also considers that because of the
particular nature of your practice ,you may have become isolated from mainstream dentistry as reflected by the lack of general dental subjects in your CPD records."

also no.22 "The committee acknowledgesthe steps you are taking which address its concerns over your failure to heed advice from medical practitioners,provision of misleading info&
permitting a patients wishes to influence your clinical judgement."

In October this dentist came to Ireland and talked about modern dentistry & informed lots of people on the dangers of amalgam,
I was sick that day,so could not go, but a friend of mine did go ,a friend whose opinion I value and trust very much said that Munro hall was a great man.and had talked about the case to him.
He said that the patient wanted the work done,believed it would help him.
