This blog article is concerned with my list of the top ten orthodontic Cochrane systematic reviews. Many years ago when Iain Chalmers was establishing the Cochrane Collaboration he came to Manchester to meet Bill Shaw about setting up an Oral Health Group. At that point I was a lecturer and I was just beginning to establish my career.  I sat in on a few of the meetings as we discussed setting up the Oral Health Group.  However, at that time I was just starting my PhD and entering the “lost years” of having to devote a large amount of time to the PhD. As a result, I could not spend time on Cochrane and I backed away from this work.

As we all know the Group has been highly successful and is one of the most active of all the Cochrane Groups.  I have taken part in several reviews and they are not easy, as you have to work to very strict protocols. Each review is a surprising amount of work, but is very worthwhile.  It is great to learn such a lot about your selected subject.

Over the past couple of weeks, I have been catching up with the orthodontic reviews and I have decided to make a list of the top ten reviews, in my opinion, and link to them from this Blog.

 “Negative” reviews

Negative-iconWhen people first starting carrying out reviews for orthodontics, they often found that the conclusion was “that there was no reliable evidence, and that more research is needed”.  This brought the quality of orthodontic research into sharp focus.  Several people were also very vocal in their criticism of reviews stating that they always concluded “that more research is required”.  This was often the case and over the years this has been rectified for some areas, for example, the treatment of Class II malocclusion. We should also remember that when a study or a review finds that there is no difference between interventions, this is not a negative result.  It is completely clear to me that this type of result allows me to discuss treatment with my patients and state that of two alternatives, neither is more effective, but we may have good reasons to decide on theirs (or my) preferences for their treatment.  So, do not be put off when you see that some of these reviews do not come to firm conclusions.  They are all equally useful, we just need to remove some of our prejudices!

So here are the top 20 in no particular order. Just click on each one to be taken to the review page in the Cochrane Library.

The list

Extraction of primary (baby) teeth for unerupted palatally displaced permanent canine teeth in children

Initial arch wires for tooth alignment during orthodontic treatment with fixed appliances

Adhesives for bonded molar tubes during fixed brace treatment

Occlusal adjustment for treating and preventing temporomandibular joint disorders

Oral appliances and functional orthopaedic appliances for obstructive sleep apnoea in children

Orthodontics for treating temporomandibular joint (TMJ) disorders

Orthodontic treatment for prominent lower front teeth (Class III malocclusion) in children

Orthodontic treatment for prominent upper front teeth in children
