The first comment I\u2019d like to make is that I am not against e-files for prep. But only in the trained and experienced hands. \u2018Trained\u2019 also includes a thorough knowledge and understanding of the nail unit, and the position and function of the nail seals.<\/p>\n\n\n\n

You may have noticed that, recently, there have been many instances of two quite rare nail conditions. These are different from the 100\u2019s of potential allergy situations.<\/p>\n\n\n\n

One of them is a green\/brown area of discolouration at the very base of the nail, almost tucked under the proximal nail fold. The other is slight to severe damage in the centre, at the base of the nail, over the lunula<\/a>. This can start with a small area of damage but can spread up the nail. It is often mistakenly recognised as a habit tic.<\/p>\n\n\n\n

Following discussions with Vitaly Solomonoff, NailKnowledge dermatologist (and nail geek), these may have two causes and both are connected with the use of e-files for prep (or other services). <\/p>\n\n\n\n

Firstly, the discolouration: the appearance of this suggests it could be a pseudomonas infection (aka \u2018greenie\u2019). It appears quite difficult to have this diagnosed. <\/p>\n\n\n\n

I realise that pseudomonas is often associated with an area of lifting between the nail coating and the nail plate. But it doesn\u2019t have to be this. This bacterium is an \u2018opportunistic\u2019 bacteria and is present, virtually, everywhere. It likes warm, damp conditions. <\/p>\n\n\n\n

So, imagine the important seal at the proximal nail fold where, together with the cuticle and the nail plate, it creates an effective watertight seal to protect the matrix. Then imagine this seal is removed, and there is a void under the fold of skin. This void can trap any amount of pathogens (and allergens) in a warm and damp environment!<\/p>\n\n\n\n
