A valuable resource on how to diagnose and treat temporomandibular disorders (TMD)

The newly and thoroughly revised 2nd Edition of Temporomandibular Disorders: A Problem-Based Approach delivers a systematic and logical approach to diagnosing and treating temporomandibular disorders.

Using a case-based approach to assist readers with understanding and retention, the book discusses the practical realities of managing patients and promoting effective treatment of temporomandibular disorders. Containing full colour clinical images and diagrams throughout, the chapters include practical guides on how to make splints and samples of patient information sheets which can be used as templates. Readers will get access to topics such as:

• The clinical aspects of anatomy, function, pathology, and classification
• Differential diagnosis of temporomandibular joint problems
• Clicking joint problems and the use of preliminary investigation in disc displacement
• Temporomandibular joint locking diagnosis and treatment, including final treatment plans
• Facial pain examinations, differential diagnosis, and questions to ask patients regarding pain in general
• Headaches, worn teeth, dislocated jaws, and more issues that arise in the treatment of temporomandibular joint problems

Perfect for undergraduate dental students and general dental practitioners, the new edition of Temporomandibular Disorders is also useful to postgraduate dental students, academics, and researchers.

About the Book

About temporomandibular disorders: what is a ‘TMD’?

The term ‘temporomandibular disorders’ (TMD) covers a constellation of conditions. There have been many attempts to categorise these conditions but all have shortfalls. Some classify by anatomy, some by aetiology, and some by frequency of presentation. We should be aware, however, that there is considerable overlap in any classification system because these are often not clinically appropriate. No one system, therefore, satisfies all the criteria.

TMD affect the articulatory system, consisting of the temporomandibular joints, mandibular muscles, and the occlusion.

Any factor that has an effect on one part of the system is likely to influence other parts of the system, so it is important to avoid tunnel vision when considering possible signs and symptoms of a TMD.

As a dentist in practice, you will inevitably encounter patients with symptoms of a TMD, who may present with facial pain, earache, toothache, jaw joint sounds, or limited movement.

It is estimated that between 50% and 70% of the population will at some stage in their life exhibit some sign of a TMD. This may be subclinical and the patient might not relate the signs to a jaw problem.

In about 20%, these signs will develop into symptoms, which implies that the patient will take notice of hitherto ignored signs, and about 5% of the population will seek treatment. This will happen if the symptoms become intrusive in day‐to‐day life. It is important for you, as a dentist, to identify these patients and recognise their particular needs and treatment requirements.

The patient may attend complaining of toothache because their natural assumption would be that a tooth was causing the problem, but your role as a clinician is to diagnose the actual cause of the symptoms.

A patient presenting with a TMD may have symptoms, in any combination, which might include preauricular or facial pain, restriction or alteration of the range of mandibular movement, muscle pain that is worse with function, localised jaw joint pain, jaw joint sounds such as clicking or crepitation, unexplained tooth sensitivity, tooth or restoration fracture, and chronic daily headache. You must be able to diagnose what is and what is not appropriate for you to treat.

All treatment should be evidence‐based. Numerous treatments, either on their own or in combination, have been proposed in accordance with various aetiological theories of TMD. A wide range of pharmacological, occlusal alteration, psychotherapeutic, and physiotherapeutic treatments have also been suggested for the management of TMD, mainly aimed at the reduction of pain and improving the range of movement.

This is possibly the area of most contention in TMD management. Several treatments have been proposed which are not evidence‐ or scientifically based and when the literature is critically evaluated it is obvious they have little rationale. It is not sufficient to argue that if a treatment modality is published in a journal, which may not be subject to peer review, be un‐refereed, or is accessible through the Internet, then it is validated. The dentist has a responsibility only to prescribe treatment for patients that has a proven therapeutic value and ignorance of currently accepted views of what a reasonable body of dentists would do is not an excuse.

All TMD managements and treatments discussed in this second edition of the book are based, as much as possible, on scientific evidence and on sound clinical judgment in cases where only partial evidence or contradictory data were found.

About the book

In modern dental schools, there is a shift from traditional teaching to more interactive methods. In classical didactic textbooks, readers are frequently seen as passive recipients of information, without any engagement in the learning process. Problem‐based learning increases the effectiveness of delivering information and makes learning a more memorable experience for the reader.

A green flag denotes a positive pathway and suggests that the reader should follow this train of thought.

A red flag signals caution and suggests that the reader should think hard about this aspect of diagnosis, investigation, or treatment.

The ‘information’ symbol indicates a passage of text that imparts fact(s) that should be remembered.

Assessment of knowledge is by a link to online self‐assessment multiple‐choice questions, which are marked correct or incorrect, and by short answer questions at the end of the book to which answers are not given because the reader needs to research the topic in the text.
