IDP Chairman,
Peter Hodgkinson, reports -
We had
a great meeting at St Mellion with John. There were 53 delegates
present.
He gave
us a précis of his week, having first spent two days touring York
before speaking to the BDA section in Hull.
He showed
us before and after radiographs of his recent knee replacement
in zirconium, and explained the similarities between orthopaedic
surgery and restorative dentistry.
He gave
us a complete history of enamel, dentine and 'wet' bonding, and
explained that the 7th generation of bonding agents were not as
effective as the 5th. He was not a great supporter of the all-in-one
bonding systems, and preferred to maintain the etch, conditioner,
bond process.
He spent
a long time explaining why dentine should always be sealed whenever
it has been cut, or even polished, and showed lots of histological
images to support how porous the dentine becomes after it has
been modified.
There were
many questions throughout the day, and although full of content
and evidence-based material, John had a very relaxed style, making
the day very entertaining and enjoyable.
