Introduction Persons with co-morbid mental and oral disorders are part of patients presenting to various dental health facilities. This presents challenges to dental personnel in terms of diagnosis and treatment .
Hence, this presentation seeks to elucidate the relevant nexus between mental and oral health

Dental Anxiety has been defined as a state of unpleasant feelings combined with an associated feeling of impending doom or danger from within rather than from without. On the other hand, dental fear is a response to a real or active threat which is usually brief.B.A. FAMUREWA, B.ChD Tuesday, August 14, 2012

Some clinical features of dental anxiety include: 1. Excessive worry over oral health and its treatment procedure 2.Recurrent unexplained symptoms of oral pathology such as oro-facial pain, headache 3. Excessive sweating most especially on the palm 4. Trembling 5.Shortness of breath 6.Somatic symptoms (such as crawling sensation, internal heat etc) 7. Palpitation.B.A. FAMUREWA, B.ChD Tuesday, August 14, 2012

Types:
1. Mild 2. Morderate 3. Severe( Dental phobia)

Epidemiology In
a recent study in Nigeria by Coker et al (2008), 29% of attendees in a dental Clinic had dental anxiety and this figure is lower than most of those obtained from studies in the western world such as Wake (1999); Moore (2004) and Kloosa et al (2007). The global estimate for dental anxiety has been put at 615% (Eli et al, 2004).
B.A. FAMUREWA, B.ChD

11
Epidemiology Dental anxiety is commoner in younger children
When compared with prevalence figure of 29% for Nigerian adults attending dental clinic, figures in children are comparatively slightly higher.For instance, Sote and Sote (1985) found 29.8% while Folayan (2000) obtained 33.7% for dental anxiety among children attendees of hospital based dental clinics in Nigeria.

MANAGEMENT
Preventive
1. Dental health education 2.Procedures should be honestly explained Definitive 1. Psychological/behavioural 2.Pharmacological
B.A. FAMUREWA, B.ChD

13
Psychological
management Minimize dental anxiety triggers; that is the 4S rule which aims to reduce the triggers of stress, such as: Sight Sound Sensation Smell
B.A. FAMUREWA, B.ChD
Tuesday, August 14, 2012
14
1.The 4S rule: Sights (of Needles, drills): placing instruments where they are blocked from view or covered. Sounds (drilling): reduce the offensive sound to
the barest minimum
Sensations (high frequency vibrations) :should be
minimized as much as possible.
Smells (Clinical odours, such as eugenol and
bonding agents): spray a scented oil fragrance to reduce the clinical aroma of the treatment room.

2.Relaxation therapies -Jacobsens muscular relaxation -Overbreathing exercise 3.Distraction techniques 4.Systematic desensitization 5.Cognitive behavioural therapy
B.A. FAMUREWA, B.ChD

Pharmacological
approach
1.Anxiolytic agents; premedication and/or parenteral .Examples Diazepam, midazolam 2.Anaesthetic agents- Nitrous oxide, Oxygen 3. Antidepressants(in chronic cases)

Substance use is the consumption of low or infrequent doses of alcohol or drugs such that damaging consequences are rare or minor. Substance abuse is a disorder characterized by repetitive drug use that results in social or economic distress with related medical problems.B.A. FAMUREWA, B.ChD Tuesday, August 14, 2012

Epidemiology Globally, 200 million people abuse drugs(2007). Studies from Nigeria showed prevalence rate of 2-9% among secondary school students; and the rates are much higher among university undergraduates.
In a Nigerian university survey, 33% of the male students and 2.2% of females admitted smoking cannabis. It is also the most incriminated substance in a survey of drug-related admissions for in-patient management in 28 psychiatric facilities in Nigeria.

Pain
is the commonest symptom seen in dentistry. Pain in the face and mouth may be of a local pathology, may be referred or may have no organic basis (psychogenic). About 50% of psychogenic pain are based in the head and neck.

Is
an abnormal belief, the patient deals with it as a fact
Examples: Delusional halitosis Phantom bite syndrome Lumps or seeds under the mucosa Management: Organic causes should be eliminated Psychological assessment & referralB.A. FAMUREWA, B.ChD Tuesday, August 14, 2012
72
This is a disorder whereby a patient complains of mouth odour that cannot be clinically substantiated or perceived by others. The patient insists in the presence of this odour despite argument to the contrary from significant others and the dental practitioners. In some of such patients, halitosis could be a manifestation of underlying uncinate fit or bizarre delusion seen in schizophrenic or severly depressed patients.B.A. FAMUREWA, B.ChD Tuesday, August 14, 2012
73
Body
dysmorphic disorder (BDD) is an obsessive preoccupation with a perceived defect in one's physical appearance. The individual persistently seeks medical attention to correct surgically. BDD often goes unrecognized and undiagnosed, due to patients' reluctance to divulge their symptoms because of secrecy and shame.B.A. FAMUREWA, B.ChD Tuesday, August 14, 2012
74
This
preoccupation causes clinically important distress or impairs work, social or personal functioning Encourages gratuitous seeking of help from various physicians thereby causing much time wasting and high expenses. The individual is never satisfied with the outcome of any corrective surgery done.B.A. FAMUREWA, B.ChD Tuesday, August 14, 2012
75
The
obsessions are most frequently focused on the head and face though any body part can be the focus of concern (most often, the skin, hair, and nose), Most patients engage in compulsive behaviors, such as mirror checking, camouflaging, excessive grooming, and skin picking. Psychiatric hospitalization, suicidal ideation, and suicide attempts are relatively common.B.A. FAMUREWA, B.ChD Tuesday, August 14, 2012
76
The patient has a serious preoccupation with an aspect of his / her physical appearance that they feel is defective Any part of the body
Facial features are the most commonly involved
Teeth and facial profile
Patient seek corrective treatment Dental treatment may enhance the patients preoccupation
Do not attempt treatment before exploring the patients expectations

characterised by persistent, stereotyped, repetitive abnormal involuntary movements of the facial muscles and the tongue associated with chronic exposure to antipsychotic drugs (especially phenothiazine) which bind and blocks the dopamine receptor.

In view of the significant interplay between the mental and oral health( illness), it is most appropriate for the dentists to have an open mind and high index of suspicion while managing patients with underlying emotional disturbance or co-morbid psychiatric disorders. This will make for prompt and accurate diagnosis, proper intervention or referral for psychiatric consultation.B.A. FAMUREWA, B.ChD Tuesday, August 14, 2012
