Dentistry – dentinogeneris imperfecta

It’s bad enough having to look at the ravages of time each morning in the bathroom mirror. When your teeth start breaking, it might be time for you to don your best sealskin coat and boots and head outdoors towards an icy oblivion.

Luckily I am not an old-fashioned Inuit, so I do not feel compelled to remove my self from the family circle. Instead I will be sitting in my dentist’s waiting room hoping they can fit me in today to smooth the jagged stump.

It’s a little embarrassing to find that  myageing is where my dental web surfing took me…

Broken Teeth
Decayed teeth, worn teeth and old fillings do break, often leaving sharp ends that the tongue plays with. This can result in tongue ulceration, which is very sore. Ideally, one should have a dentist smooth off the sharp piece as soon as possible. However, if this is not possible, usually within a couple of days, the tongue loses interest in the sharp object and the ulcer will heal.

Genes are largely responsible for the destruction in my mouth, and the Latin in this blog’s title. For those of a curious nature, here is a definition from  a Lithuanian dental site:

Genetic teeth disorders may be divided into two categories: the ones that cause dental abnormalities in babies (primary development) and the ones that impact adults (secondary development). Also, genetic diseases can affect the physical appearance of teeth.

The most common disorders are amelogenesis imperfecta, dentinogenesis imperfecta, dentin dysplasia, regional odontodysplasia, taurodontism, tricho – dento – osseous syndrome, oculodentodigital dysplasia, Hallermann-Streiff syndrome, Marfan syndrome, Ehlers-Danlos syndrome and cleidocranial dysostosis.

Dentinogenesis imperfecta

It is another teeth development disorder. In this condition teeth are discoloured and transparent. They can be blue-grey or yellow–brown. Both primary and secondary teeth are damaged. They are weaker, easy to damage and prone to falling out. There are 3 types of osteogenesis imperfecta. In type 2 and 3 mutation of DSPP gene occurs (autosomal dominant trait). Type 1 is inherited in autosomal recessive way. This gene contains instructions for making two proteins which are necessary for normal teeth development.

I won’t be jumping on any flights to Lithuania just yet. In the UK we are very fortunate to have highly trained dentists still prepared to work for the NHS, despite the fact that there are much richer pickings in private practice.
