Foreword

The everyday clinical practice of dentistry includes aspects of oral medicine. Lesions and abnormalities of the soft tissues of the mouth and orofacial region are common, with many conditions being indicative of systemic disease and disorders. Knowledge, understanding and the effective practice of oral medicine are therefore integral to the provision of holistic oral healthcare.

Oral medicine, in common with all other aspects of dentistry, continues to evolve at an ever increasing rate. This volume of the unique Quintessentials of Dental Practice series captures the essence of modern oral medicine for, in particular, the busy practitioner. From immunological problems through lumps and bumps, infections and white patches to premalignant lesions and oral cancers, together with sections on oral pigmentation, disorders of salivary glands and salivation, facial pain, neurological disorders and complementary therapies, this Quintessentials volume provides essential chairside information and guidance. Aficionados of Quintessence books and, in particular, the Quintessentials series will be pleased to recognise all the qualities they have come to expect: succinct, easy to digest, up-to-date text, well illustrated with high quality graphics and images.

This book is both a valuable, close-to-hand reference text and a pleasure to indulge in over the one or two evenings it takes to complete the cover to cover read. A gem of a book in the world-class Quintessentials series. I hope you enjoy and discover new dimensions to oral medicine from this excellent addition to the ongoing series.

Chapter 1

Introduction and Oral Medicine in Clinical Practice

Aim

The aim of this chapter is to outline the development of oral medicine and to describe the oral medicine consultation.

Outcome

After reading this chapter you should understand the importance and structure of an oral medicine consultation.

Introduction

Oral medicine has been defined as ‘the speciality of dentistry concerned with the health care of patients with acute or chronic, recurrent and medically related disorders of the oral and maxillofacial region, and with their diagnosis and medical management. It is also concerned with the investigation, aetiology and pathogenesis of these disorders leading to understanding that may be translated into clinical practice. Oral medicine is a clinical and academic speciality that is dedicated to the investigation, diagnosis, management and research into medically related oral diseases, and the oral and facial manifestations of systemic diseases. These include diseases of the gastrointestinal, dermatological, rheumatological and haematological systems, autoimmune and immunodeficiency disorders, and the oral manifestations of neurological and psychiatric diseases.’

The practice of oral medicine requires a sound knowledge of medical science in order to provide a rational approach to diagnosis and clinical management. It is also essential for the competent provision of dental care to those with special needs – patients with physical, mental or medical disability.

Oral medicine permeates virtually all branches of dentistry and many areas of medicine. It can be regarded as the interface between medicine and dentistry. This book covers in a practical manner the scope of oral medicine most likely to be encountered in a dental setting. It does not pretend to be all-inclusive, and readers are advised to make reference to more specialist publications where appropriate. Some of these are suggested at the end of each chapter. In addition, some conditions more usually managed by maxillofacial, ear, nose and throat (ENT) or plastic surgery have been deliberately excluded.

The Oral Medicine Consultation

The initial appointment is often the most important time in patient’s management. This meeting sets the tone for all remaining visits. The patient forms opinions about the expertise and competence of the practitioner. The clinician forms views about the patient and his or her problem. As communication, empathy and trust form a large part of treatment, it is important that the process gets off to a good start on both sides.

An effective practitioner will manage to put patients at their ease. This can establish trust, allowing full disclosure of information relevant to the problem to be obtained. Many factors are important in this. The following can all play a part:

One of the most important lessons for the inexperienced clinician to learn is when not to talk and to encourage the patient to keep providing information. It is important to retain control of the consultation, however, and not be afraid to redirect patients when they digress from pertinent information.

The stages of the consultation are as follows:

Each stage is important and will take place at every consultation, but the emphasis on each will vary between initial and review consultations.

Greeting

This is the first contact between the patient and the clinician. It may occur when collecting the patient from the waiting area or as the patient enters the surgery. The clinician should greet the patient in an open and welcoming manner, introducing himself and all other people present at the consultation by giving their name, position and their role. The patient should be seated comfortably, facing the clinician in preparation for the next stage of the consultation. If the patient has brought a supporter, ideally he or she should be seated able to face and communicate with the patient and the clinician. Where possible all individuals in the consultation room should be easily visible to the patient, as this helps relaxation.

Introduction

The clinician should outline the purpose of the appointment – for example, a referral from another practitioner, a review of investigation results or treatment progress. An outline of the process of the consultation is appropriate at the initial visit, informing the patient of the different stages to expect – history, review and the possible need for discussion with other health care workers, special investigations and arrangements for management. Many complaints from patients relate to communication failures rather than to treatment problems. It is important that the patient and the clinician are equally clear about the purpose and scope of the consultation at this visit.

Information-Gathering

The history should follow a standard format to enable reproducibility. A sample history-taking plan is given in Table 1-1. Some aspects of the history process will be identical for all patients and some – in particular, the history of the presenting complaint – will vary according to the problem. Some of the key issues in a patient with recurrent oral ulceration will be of little relevance in someone with chronic facial pain, but a thorough medical and social history will be important for both. In this book, where there is information required for a particular oral complaint, the specific history points to cover will be reviewed in the appropriate chapter. All sources of information including, if appropriate, the opinions of the supporter, can be important and should be canvassed. At the end of the history, it is helpful to read back to the patient the clinician’s understanding of the presenting problem, its course and management to this point. Any misunderstandings or misinterpretations on the part of the clinician can then be set aside at an early stage.

Table 1-1 Information to be obtained from each patient
For each patient the following information must be obtained
  • Name, age and gender

  • Presenting complaint (PC) or reason for referral (RR) if symptom-free

  • History of presenting complaint (HPC)

    • Who noticed the lesion/condition? – when it was noticed

    • Site of problems – intra-oral/extra-oral

    • Symptomatic – what symptoms reported? Duration of symptoms?

    • Periodicity of symptoms – variations during the day/day to day/week to week?

    • Precipitating and relieving factors – foods/eating, analgesia effect? Others?

    • Treatments tried so far – success? the most helpful? unhelpful?

    • For painful lesions – score/10 – At worst? At best? Today? Average? (10/10 – worst pain imaginable, 0/10 – no pain)

    • Associated symptoms – for example, skin, muscle/joint, genital, gastrointestinal system

  • Past medical history

    • Serious illnesses and operations in the past

    • Current attendance at hospital, clinic or GP – why?

    • Current medications – (no dosage needed) NB: Record generic drug name only, not drug ‘trade’ name

    • Allergies to medicines – record the effect the drug produced as well

  • Systems enquiry:

Check particularly:

    • Cardiovascular

Angina, previous myocardial infarction

    • Respiratory

Asthma/chronic obstructive pulmonary disease (use of inhalers?), smoker (what quantity?)

    • Gastrointestinal

Dyspepsia, ulcers, altered bowel habit, bleed PR

    • Urinary

Prostatism (men!)

    • Skin

Rashes, itch, eczema

    • Specific diseases

Rheumatic fever, jaundice, diabetes, epilepsy

    • Family history

illnesses known in blood relatives? (myocardial infarction, cerebrovascular accident, diabetes)

    • Social history

Who is at home? Are they well?
Actual/desired employment? Happy at work?
Alcohol consumption history

Examination, Diagnosis and Treatment
  • Clinical findings on examination

    • Observation of the patient – appearance, demeanour

    • Extra-oral findings – nodes, salivary swellings, tenderness of soft tissues, cranial nerve function, pigmentation changes, scars

    • Intra-oral findings – full mucosal examination, general dental condition, periodontal and dental charting as needed

    • Results of special investigations today for example, salivary flow, Schirmer test, cranial nerve exam

  • Further investigations ordered – imaging, histopathology and biopsy

  • Treatment plan

    • Note if discussed with colleague

    • Bullet point or number items

    • Record those completed today

    • Outline purpose of next visit

  • Sign and date record in case record

  • Ensure appropriate letters are dictated

A full clinical examination of the head and neck should then take place. Depending on the differential diagnosis, the expertise of the clinician, local clinical practice and facilities, a more complete physical examination of the patient may also be appropriate (Figs 1-1 to 1-3).

Review and Discussion

After the examination it is useful to summarise the key points elicited in the examination and relate these to the history. From this the patient can see how the clinician has reached the offered diagnosis, or where there is a need for proposed investigations. In most oral medicine problems, the patient will be the ‘key worker’ in the delivery of treatment. It is therefore essential that the patient accepts the diagnosis and treatment plan suggested. In addition, the patient should understand the likely outcome, effects and timescale of the proposed treatment. The patient and, if appropriate, the supporter should be invited to ask questions about the diagnosis and proposed treatment. Where possible, written information should be given. This may be a full information leaflet, if available, but simply writing the name of the diagnosis and proposed treatment on paper to hand to patients can be helpful. This will aid understanding of their condition and ultimately their involvement in and compliance with treatment.

Conclusion and Future Planning

At the end of the initial consultation the patient should be made aware of investigations planned, the likely duration of the treatment and the planned intervals for review. It is useful to explain why a particular interval is chosen – for example, two-month intervals rather than one month – as this will help the patient understand the treatment process. Similarly it is important to ensure that the patient knows how to contact the clinician should the situation or condition change so that a new review interval or unscheduled appointment can be arranged. If it is decided to refer to a more appropriate specialist, the reason and mechanism for this should be clearly explained. The general medical practitioner can often play a pivotal role in the provision of care for oral medicine conditions, in many cases providing the treatment for the patient according to the treatment plan. If urgent medication is required, it may be necessary to contact the general medical practitioner asking for a particular treatment to be made available quickly or to dispense directly to the patient from the clinic.

At the end of the consultation patients should have a clear understanding of their future care plan. Notes should be completed promptly and letters sent to appropriate people, usually including the general medical practitioner. The general medical practitioner is often the only person aware of the ‘bigger picture’ in the patient’s care and, as a consequence, should routinely be included in all correspondence.

Chapter 2

Immunological Problems of the Oral Mucosa

Aim

The aim of this chapter is to review immunological oral disease, including lichen planus, oro-facial allergic disorders, recurrent aphthous stomatitis, mucocutaneous autoimmune disorders, vasculitis and systemic autoimmune disorders presenting in the head and neck region.

Outcome

After reading this chapter you should be able to understand the features of immunological disease affecting the head and neck, together with the systemic effects of these diseases and factors influencing their presentation or management.

Introduction

Immunological oral disease is a very broad subject. Many mucosal and periodontal problems are caused either directly or indirectly by the host’s immune system. Some oral manifestations represent mouth changes as part of a whole body process, and other conditions produce lesions or symptoms mainly or only in the mouth. In this chapter immunological problems, including the oral effects of allergy, will be reviewed together with the oral mucosal effects of immunological reactions to the oral mucosa.

Orofacial Allergic Disorders

Allergy is usually classified by its four main methods of presentation:

Many patients presenting with allergy-related disease will have a history of atopy, such as eczema or asthma. The presentation of allergy in the oral soft tissues may be very varied. Gingival hyperplasia may be found in patients with allergic nasopharyngeal reaction, resulting in tissue desiccation secondary to mouth-breathing. Gingival erythema may be the result of a toothpaste allergy, often leading to a significant plasma cell infiltrate and the clinical appearance of a desquamative gingivitis. Allergy can be the basis of many other oral mucosal diseases not primarily considered ‘allergic’ disorders. These include recurrent aphthous ulceration and lichen planus. There is also an association with geographic tongue, but there is no good evidence suggesting a causal relationship.

Type 1 Reactions

These are produced by the rapid movement of fluid into the tissues from the circulation and are characterised by rapidly increasing swelling of the tissues and, following removal of the stimulus, gradual resolution over a period of hours. In this condition the transudation of fluid into the tissues from the capillaries is more rapid than the capacity of the lymphatics to drain the fluid away. This can be seen in patients with angio-oedema of the lips or tongue such as may be triggered by ACE-inhibiting drugs or C1 esterase dysfunction.

Angio-oedema

In this condition the patient will report rapid lip swelling over less than an hour with gradual resolution over the remainder of the day. Most patients with these symptoms do not seem to have a recognisable trigger, and empirical management with a long-acting, non-sedating antihistamine is the mainstay of treatment.

The combination of angio-oedema with bronchospasm, vasodilatation and rapid hypotension suggests another type 1 reaction – anaphylaxis. This reaction may follow dental treatment, such as a reaction to latex containing gloves worn by the dental team, or more rarely a local anaesthetic injection. Environmental triggers, such as a bee or wasp sting, are also possibilities, and an anaphylactic reaction should never be discounted only because no drug has been administered to the patient.

Type 2 Reactions

There are no oral conditions commonly associated with a type 2 reaction.

Type 3 Reactions
