Periodontics

Applying the new periodontal disease classification (2017) in general dental practice

Hasn’t it always felt like there is a new perio disease classification, or a new one coming soon? Although this is not exactly endodontics, it is still relevant. Apart from anything else, to communicate effectively we all need to talk the same dialect and it looks like this new 2017 classification, produced jointly by the AAP and ESE is here to stay! This is my take on how to make it easy to use in practice.

Do they meet? All about canal confluences

There’s something about confluences, something to beware of. The meeting of two entities often stirs up a sense of foreboding, apprehension, something not quite desired. As in literature, so in endodontics. Confluences look so innocuous and can look so satisfying on the final PA when properly treated, but handled incorrectly they may lead you to “deep water”…

Irrigation – how should I irrigate? Part 2: irrigant agitation, interactions and protocols

Why is irrigant agitation necessary? Passively “squirting” the irrigant into the canal and expecting it to intimately contact the whole canal surface is misguided because: Surface tension prevents irrigant penetrating all the fine tributaries (isthmuses, lateral canals, apical delta, fins) in the canal system. A vapour lock may form in the canal, which is a small gas bubble that either remains trapped, or forms at the apex (Senia et al. 1971). If it does, the bubble prevents irrigant contacting the canal surface and exerting its desirable properties in what is the most critical part of the canal. Even if there is no vapour lock, if you don’t (or can’t) place the needle sufficiently…

Irrigation – how should I irrigate? Part 1: properties and delivery of irrigants

This two part post looks at the irrigation of root canal systems. I’ll start in this post with the ‘why’ and then in the next post move on to the ‘how’ of irrigation, concentrating the practicalities of the clinical implementation of effective irrigation in general dental practice. So, part 1 deals with the why of irrigation, properties of irrigants and delivery of irrigants into the root canal. Part 2 will discuss irrigant activation and recommended irrigant protocols. First, why irrigation? Pulpal and endodontic disease are caused by microbial infection of the canal system (Kakehashi et al 1965). Root canals may be infected by a variety of microrganisms cocci,…

About EndoGen.net

Definition of Endo|Gen Endo|Gen  /’ɛndəʊ’dʒɛn/ n.  A blog providing up-to-date and practical information addressing the wide variety of problems encountered by dentists in their practice of endodontics, whilst respecting the need to integrate it with the evidence-base that underpins high quality root canal treatment.  [alt. of Endodontic|Knowledge] What is the background to Endo|Gen? The chances are you qualified with minimal knowledge of, or experience in, root canal treatment (RCT) and, with this basic understanding, you were expected to just get on with it. Perhaps you sought the advice of other dentists in your practice, but later discovered that the usefulness of their advice was limited by them doing what…
